Description

Wärmetauscher und Konvektoreinheit aus Wärmetauschern Heat exchanger and convector unit from heat exchangers

Die Erfindung betrifft einen Wärmetauscher zum Erwärmen und/oder Kühlen von Luft insbesondere von Raumluft mit mehreren von einem Fluid durchströmbaren Rohren, die zur Vergrößerung der Heiz- und/oder Kühlfläche mit Lamellen verbunden sind. Ferner betrifft die Erfindung eine Konvektoreinheit, die aus Wärmetauschern zusammengesetzt ist.The invention relates to a heat exchanger for heating and / or cooling of air in particular of room air with a plurality of pipes through which a fluid can flow, which are connected to increase the heating and / or cooling surface with fins. Furthermore, the invention relates to a convector unit, which is composed of heat exchangers.

Es sind Wärmetauscher unterschiedlichster Größe und Bauart bekannt. Hierbei ist die Baugröße von der gewünschten Leistung abhängig, so dass je nach erforderlicher Leistung unterschiedlich große Wärmetauscher hergestellt werden. Dies erfordert einen erheblichen Konstruktions- und Herstellungsaufwand, bei dem eine Automatisierung nur bei hohen Stückzahlen wirtschaftlich ist.There are known heat exchangers of different sizes and types. Here, the size depends on the desired performance, so that depending on the required power different sized heat exchangers are manufactured. This requires a considerable design and manufacturing effort, in which automation is only economical in large quantities.

Aufgabe der Erfindung ist es, einen Wärmetauscher zu schaffen, der bei hoher Übertragungsleistung und kleiner Druckdifferenz in Konstruktion und Herstellung einfach ist und hierbei geringe Außenabmessungen aufweist und vielseitig einsetzbar ist. Auch ist es Aufgabe der Erfindung, dass der Wärmetauscher seine Wärmeabgabe sowohl konvektiv als auch zeitgleich als Strahlung abgibt.The object of the invention is to provide a heat exchanger which is simple in construction and production with high transmission power and small pressure difference and this has small outer dimensions and is versatile. It is also an object of the invention that the heat exchanger emits its heat both convective and at the same time as radiation.

Darüber hinaus ist Aufgabe der Erfindung, einen Wärmetauscher der eingangs genannten Art in Konvektoren unterschiedlichster Leistung verwenden zu können, ohne den Wärmetauscher selber verändern zu müssen. Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass eine Mehrzahl von Rohren parallel zueinander angeordnet und aneinander befestigt sind und eine Wärmetauscherwand bilden, die einen Wärmetauscherinnenraum umschließt, der von der zu erwärmenden und/oder zu kühlenden Luft durchströmbar ist, und dass an und/oder zwischen den Rohren die Lamellen befestigt sind.In addition, the object of the invention to use a heat exchanger of the type mentioned in convectors of different performance, without having to change the heat exchanger itself. This object is achieved in that a plurality of tubes are arranged parallel to each other and attached to each other and form a heat exchanger wall, which encloses a heat exchanger interior, which can be flowed through by the air to be heated and / or cooled, and on and / or between the tubes are attached to the tubes.

Ein solcher Wärmetauscher besteht im Wesentlichen nur aus zwei Bauteilen, d. h. aus einem Rohr, aus dem die Wärmetauscherwand zusammensetzbar ist und am oder zwischen den Rohren befestigten Lamellen. Damit hängt die Leistung des Wärmetauschers nur noch von der Anzahl und der Größe der Rohre und Lamellen ab. Dies erleichtert eine maschinelle Fertigung und ermöglicht einen hohen Automatisierungsgrad.Such a heat exchanger consists essentially only of two components, d. H. from a tube from which the heat exchanger wall can be assembled and lamellae mounted on or between the tubes. Thus, the performance of the heat exchanger depends only on the number and size of the tubes and fins. This facilitates machine production and enables a high degree of automation.

Darüber hinaus kann der Wärmetauscher insbesondere durch seine Patronenform als Einzelelement mehrfach nebeneinander in Konvektoreinheiten eingesetzt werden, ohne Änderungen am Wärmetauscher vornehmen zu müssen. Damit bestimmt nicht mehr die individuelle Größe des Wärmetauschers, sondern die Anzahl der Wärmetauscher die Leistung der Konvektoreinheit.In addition, the heat exchanger can be used in particular by its cartridge shape as a single element multiple side by side in convector units, without having to make changes to the heat exchanger. This no longer determines the individual size of the heat exchanger, but the number of heat exchangers the performance of the convector unit.

Ferner kann ein solcher Wärmetauscher sowohl zum Kühlen als auch zum Erwärmen von Luft sowie in senkrechter als auch in waagerechter oder schräger Lage verwendet werden. Darüber hinaus ist ein solcher Wärmetauscher sowohl mit als auch aufgrund der niedrigen Druckdifferenz ohne Ventilator verwendbar.Furthermore, such a heat exchanger can be used both for cooling and for heating air as well as in vertical as well as in horizontal or inclined position. Moreover, such a heat exchanger can be used both with and because of the low pressure difference without a fan.

Eine gerundete Wärmetauscherwand ist dann auf konstruktiv einfache Weise erreichbar, wenn die den benachbarten Rohren zugewandten zwei Seitenflächen jeden Rohres derart zueinander schräg verlaufen, dass ihr Abstand voneinander zum Wärmetauscherinnenraum hin sich verringert. Hierbei können die Rohre einen trapezförmigen Querschnitt aufweisen.A rounded heat exchanger wall can then be achieved in a structurally simple manner if the adjacent tubes facing two side surfaces of each tube obliquely to each other so that their distance from each other to the heat exchanger interior towards decreases. In this case, the tubes may have a trapezoidal cross-section.

Vorzugsweise wird vorgeschlagen, dass die Rohre einen Innenkanal mit rundem oder ovalem Querschnitt aufweisen. Auch ist von Vorteil, wenn die Wärmetauscherwand einen im Querschnitt kreisförmig oder ovalen Wärmetauscherinnenraum bildet. Die Befestigung der Rohre aneinander kann vielseitig gestaltet sein und erfolgt miteinander kraft-, Stoff- oder formschlüssig. Vorzugsweise erfolgt sie stoffschlüssig, da eine beste Wärmeübertragung gegeben ist.It is preferably proposed that the tubes have an inner channel with a round or oval cross-section. It is also advantageous if the heat exchanger wall forms a cross-sectionally circular or oval heat exchanger interior. The attachment of the tubes to each other can be designed versatile and takes place together force, material or form-fitting. Preferably, it takes place cohesively, since a best heat transfer is given.

Besonders vorteilhaft ist es, wenn die Lamellen in den Wärmetauscherinnenraum insbesondere radial hineinragen. Hierbei können die Lamellen sich bis zur Mitte des Wärmetauscherinnenraums erstrecken. Hierbei ist von Vorteil, wenn die Lamellen sich zur Mitte des Wärmetauscherinnenraums in gebogener Form erstrecken und mit ihren inneren gebogenen Rändern einen koaxialen Kanal bilden, wobei die Lamellen mit ihren inneren Rändern aneinander befestigt sind.It is particularly advantageous if the lamellae protrude into the interior of the heat exchanger, in particular radially. In this case, the fins can extend to the middle of the heat exchanger interior. It is advantageous if the lamellae extend to the center of the heat exchanger interior in a curved shape and form a coaxial channel with their inner curved edges, wherein the lamellae are fastened with their inner edges together.

Um ein sicheres Ablaufen von Kondensat zu erreichen, wird vorgeschlagen, dass der untere Rand der Lamellen derart schräg geformt ist, dass der Randbereich nahe der Wärmetauscherwand tiefer liegt als der weiter innen liegende Randbereich. Hierbei kann unterhalb der Lamellen an der Innenseite der Wärmetauscherwand eine Auffangrinne für das Kondensat angeordnet sein. Besonders vorteilhaft ist hierbei, wenn die gebogene Innenwand der Auffangrinne den insbesondere düseπförmigen Lufteiniass des Wärmetauschers bildet.In order to achieve a reliable drainage of condensate, it is proposed that the lower edge of the slats is formed obliquely so that the edge region near the heat exchanger wall is lower than the inner edge region. Here, a collecting channel for the condensate can be arranged below the slats on the inside of the heat exchanger wall. In this case, it is particularly advantageous if the curved inner wall of the collecting channel forms the particular nozzle-shaped air aisle of the heat exchanger.

Vorzugsweise wird vorgeschlagen, dass unterhalb oder oberhalb der Lamellen ein Ventilator insbesondere im Wärmetauscherinnenraum angeordnet ist. Ein einfaches Beeinflussen der Luftströmung, hier besonders die Austrittsgeschwindigkeit für zugfreien Eintrag, wird erreicht, wenn in oder an der Auslassseite ein verstellbares Ventil insbesondere mit lamellenförmigen Verschlussteilen angeordnet ist.It is preferably proposed that below or above the slats a fan is arranged in particular in the heat exchanger interior. A simple influencing of the air flow, here in particular the exit speed for draft-free entry, is achieved if an adjustable valve, in particular with lamellar closure parts, is arranged in or on the outlet side.

Besonders vorteilhaft ist es, wenn eine erste Gruppe mehrerer nebeneinander liegender Rohre zum Erwärmen von Luft und eine zweite Gruppe mehrerer nebeneinander liegender Rohre zum Kühlen von Luft mit den entsprechenden Heiz- und Kühlaggregaten verbunden ist. Hierbei kann die erste Gruppe von Rohren die Vorderseite des Wärmetauschers bilden. Auf konstruktiv einfache Weise wird eine Konvektoreinheit mit solchen Wärmetauschern dann geschaffen, wenn zwei oder mehr rohrförmige Wärmetauscher zu einer Konvektoreinheit aneinander befestigt sind. Hierbei ist von Vorteil, wenn die Achsen der Wärmetauscher zueinander parallel liegen. Eine besonders vorteilhafte Ausführungsform ist gegeben, wenn die Wärmetauscher miteinander eine gerade Reihe bilden. Die Wärmetauscher sind zu einer Konvektoreinheit baukastenförmig leicht aneinander befestigbar, wenn die Wärmetauscher formschlüssig insbesondere durch Steckverbindungen aneinander befestigt sind.It is particularly advantageous if a first group of several adjacent tubes for heating air and a second group of several adjacent tubes for cooling air are connected to the corresponding heating and cooling units. Here, the first group of tubes form the front of the heat exchanger. In a structurally simple manner, a convector unit with such heat exchangers is created when two or more tubular heat exchangers are attached to a convector unit to each other. It is advantageous if the axes of the heat exchanger are parallel to each other. A particularly advantageous embodiment is given when the heat exchangers together form a straight row. The heat exchangers can be fastened to one another in a modular manner in a modular manner when the heat exchangers are fastened to each other in a form-fitting manner, in particular by means of plug-in connections.

Ein einfaches Verstellen aller Wärmetauscher einer Konvektoreinheit ist gegeben, wenn die Ventilverschlussteile und/oder Auswürfe durch ein Gestänge verbunden und verstellbar sind. Vorzugsweise wird vorgeschlagen, dass neben oder zwischen den rohrförmigen Wärmetauschern ein rohrförmiges Gehäuse gleicher Form und Größe wie die Wärmetauscher angeordnet ist, das technische Mittel wie Stellantrieb, Elektrik und/oder Elektronik enthält.A simple adjustment of all heat exchanger of a convector unit is given if the valve closure parts and / or ejections are connected by a linkage and adjustable. Preferably, it is proposed that, in addition to or between the tubular heat exchangers, a tubular housing of the same shape and size as the heat exchanger is arranged, which contains technical means such as actuator, electrical and / or electronics.

Hierbei besitzen die Rohre einen koaxialen Innenkanal 4 und zwei Seitenflächen 3a, 3b, die zueinander leicht schräg verlaufen, um miteinander einen spitzen Winkel zu bilden, dessen Scheitelpunkt auf der Längsachse des Wärmetauschers liegt. Die Seitenflächen 3a, 3b liegen damit jeweils auf einem Radius der im Querschnitt kreisförmigen Wand 2, wobei der Querschnitt jeden Rohres 3 außenseitig ein gleichschenkliges Trapez bilden. Hierbei können aber die Außenfläche 3c und die Innenfläche 3d von einem Trapez dadurch abweichen, dass die Außenfläche 3c konvex und die Innenfläche 3d des Rohres 3 konkav in einer Weise gewölbt sind, dass die Außenflächen 3c aller Rohre die zylindrische Außenseite des Wärmetauschers und die Innenflächen 3d aller Rohre die zylindrische Innenfläche des Wärmetauschers bzw. der Wand 2 bilden. Hierbei weist der Innenkanal 4 der Rohre 3 vorzugsweise einen kreisförmigen oder ovalen Querschnitt auf. Alternativ kann der Wärmetauscher aber auch eine nichtzylindrische Form besitzen und z.B. quaderförmig sein.The heat exchanger 1 according to the invention has an outer wall 2, which is composed of a plurality of tubes 3. Here, the tubes have a coaxial inner channel 4 and two side surfaces 3a, 3b, which extend slightly obliquely to each other to form an acute angle with each other, whose apex lies on the longitudinal axis of the heat exchanger. The side surfaces 3a, 3b are thus each on a radius of the circular cross-section wall 2, wherein the cross section of each tube 3 on the outside form an isosceles trapezoid. Here, however, the outer surface 3c and the inner surface 3d may deviate from a trapezoid in that the outer surface 3c convex and the inner surface 3d of the tube 3 are concavely curved in such a manner that the outer surfaces 3c of all tubes are the cylindrical outer surface of the heat exchanger and the inner surfaces 3d all tubes form the cylindrical inner surface of the heat exchanger or the wall 2. In this case, the inner channel 4 of the tubes 3 preferably has a circular or oval cross-section. Alternatively, however, the heat exchanger may also have a non-cylindrical shape and e.g. be cuboid.

Zwischen den Rohren 3 und damit zwischen den Seitenflächen 3a und 3b sind Lamellen 5 befestigt insbesondere eingelötet. Hierzu können die Lamellen außenseitig mit einem Lot beschichtet sein. In einer nicht dargestellten Ausführung sind die Rohre 3 nicht aneinander gelötet, sondern durch einen Außenmantel oder durch Außenringe aneinander gehalten.Between the tubes 3 and thus between the side surfaces 3a and 3b slats 5 are fixed in particular soldered. For this purpose, the lamellae can be coated on the outside with a solder. In an embodiment, not shown, the tubes 3 are not soldered to each other, but held together by an outer sheath or by outer rings.

Stattdessen können die Lamellen 5 aber auch nur an der Innenseite der Wand 2 und damit an der Innenfläche 3d der Rohre befestigt sein insbesondere durch Anlöten. Die Lamellen erstrecken sich von der Wand 2 nach innen zur inneren Mitte des von der Wand 2 umgebenden Innenraums 6. Hierbei sind die Lamellen 5 in der in den Fig. 2 und Fig. 4 dargestellten Ausführung in der Weise gebogen hergestellt, dass sie einen inneren koaxialen Kanal 7 bilden, wobei die inneren Enden der Lamellen 5 durch tangentiale Lage die Wand des Kanals 7 bilden. Die sich zur Mitte des Innenraums 6 erstreckenden Lamellen 5 haben die wesentliche Funktion, durch den Innenraum 6 geführte Luft zu erwärmen oder abzukühlen, so dass der Wärmetauscher sowohl als Heizelement als auch als Kühlelement verwendbar ist. Hierbei können die Anschlüsse an die Innenkanäle 4 der Rohre 3 derart vorgesehen sein, dass nur eine bestimmte Anzahl von Rohren 3 der Erwärmung dienen, im folgenden als erste Gruppe 8 bezeichnet, s. Fig. 2. Die übrigen Rohre der zweiten Gruppe 9 dienen hierbei der Kühlung, wobei eine Gruppe 8 von nebeneinander liegender Rohre kleiner sein kann als die in der zweiten Gruppe 9. Vorzugsweise bildet hierbei die erste Gruppe 8, die der Erwärmung dient, mit ihrer Außenseite die Außenwand des Wärmetauschers, die dem Raum bzw. den Benutzern zugekehrt ist, um damit Wärmestrahlung nach außen abzugeben.Instead, however, the slats 5 can also be fastened only on the inside of the wall 2 and thus on the inner surface 3d of the tubes, in particular by soldering. The lamellae extend inwardly from the wall 2 to the inner center of the inner space 6 surrounding the wall 2. Here, the lamellae 5 in the embodiment illustrated in FIGS. 2 and 4 are bent in such a way that they have an inner form coaxial channel 7, wherein the inner ends of the slats 5 form the wall of the channel 7 by tangential position. The lamellae 5 extending to the center of the interior 6 have the essential function of heating or cooling air conducted through the interior space 6, so that the heat exchanger can be used both as a heating element and as a cooling element. Here, the connections to the inner channels 4 of the tubes 3 may be provided such that only a certain number of tubes 3 are used for heating, hereinafter referred to as the first group 8, s. FIG. 2. The remaining tubes of the second group 9 serve for cooling, whereby a group 8 of adjacent tubes may be smaller than those in the second group 9. Preferably, the first group 8, which serves for the heating, forms with it Outside the outer wall of the heat exchanger, which faces the room or the user, so as to give heat radiation to the outside.

Zu beiden Enden der Wand 2 und damit der Rohre 3 ist jeweils ein Endteil 10, 11 befestigt, das Ringkanalsegment12 zur Versorgung der Kanäle aufweist. In einem der beiden ringförmigen Endteile 10 ist ein Ventilator 24 angeordnet, der dafür sorgt, dass Luft durch den Innenraum 6 strömt.To each end of the wall 2 and thus of the tubes 3 is in each case an end portion 10, 11 fixed, the Ringkanalsegment12 has to supply the channels. In one of the two annular end portions 10, a fan 24 is arranged, which ensures that air flows through the interior space 6.

In dem in Fig. 1 dargestellten Ausführungsbeispiel liegt der Wärmetauscher waagerecht oder leicht schräg angeordnet, so dass das Kondensat 17 von den Lamellen nach unten fließt und von dort gesammelt nach außen zum Endteil 11 und dort in eine Auffangrinne 14, die von einer ringförmigen Endfläche 15 gebildet wird. Hierbei ist die ringförmige Auffangrinne 14 derart abgerundet gestaltet, dass die Innenöffnung 16 einen abgerundeten Rand für die Öffnung 16 bildet.In the embodiment shown in FIG. 1, the heat exchanger is arranged horizontally or slightly obliquely, so that the condensate 17 flows from the fins down and collected from there outwards to the end portion 11 and there into a gutter 14, of an annular end surface 15th is formed. Here, the annular collecting channel 14 is designed rounded so that the inner opening 16 forms a rounded edge for the opening 16.

In Fig. 5 ist der Wärmetauscher in senkrechter Stellung im Kühlbetrieb dargestellt. Wird hierbei ohne Ventilator gearbeitet, so strömt die zu kühlende Luft in Richtung der Pfeile 18 nach unten. Mit Unterstützung des Ventilators 24 wird die Luft vorzugsweise nach oben in Richtung der Pfeile 19 bewegt. Mit den Pfeilen 17 ist die Strömungsrichtung des Kondensats dargestellt, das nach unten strömt, wobei die Unterseiten der Lamellen 5 derart schräg geformt sind, dass der Randbereich der Lamelle nahe der Wärmetauscherwand tiefer liegt als der weiter innen liegende Randbereich, so dass entlang dieser unteren Kante 20 der Lamelle das Kondensat nach außen fließt, um in die Auffangrinne 14 zu gelangen.In Fig. 5, the heat exchanger is shown in the vertical position in the cooling mode. If this is done without a fan, the air to be cooled flows in the direction of arrows 18 down. With the assistance of the fan 24, the air is preferably moved upwards in the direction of the arrows 19. The arrows 17 show the direction of flow of the condensate, which flows downwards, wherein the undersides of the lamellae 5 are obliquely shaped such that the edge region of the lamella near the heat exchanger wall is lower than the further inner edge region, so that along this lower edge 20 of the Slat the condensate flows outward to get into the gutter 14.

In Fig. 6 ist eine Konvektoreinheit 21 dargestellt, die aus drei zylindrischen bzw. patronenförmigen Wärmetauschern 1 zusammengesetzt ist. Hierbei sind die einzelnen Wärmetauscher durch Steckverbindungen 22 aneinander insbesondere lösbar befestigt. Die Anzahl der einzelnen gleich großen und damit dieselbe Leistung erbringenden Wärmetauscher 1 innerhalb einer Konvektoreinheit ist direkt abhängig von der gewünschten Gesamtleistung der Konvektoreinheit. Dabei liegen die einzelnen Wärmetauscher mit ihren Längsachsen stets parallel zueinander.In Fig. 6, a convector unit 21 is shown, which is composed of three cylindrical or cartridge-shaped heat exchangers 1. Here, the individual heat exchangers are fastened to each other in particular releasably by connectors 22. The number of individual heat exchangers 1, which have the same size and therefore the same output, within a convector unit is directly dependent on the desired overall output of the convector unit. The individual heat exchangers are always parallel to one another with their longitudinal axes.

Auf einer Seite der Reihe von Wärmetauschern 1 oder zwischen diesen ist vorzugsweise ein rohrförmiges Gehäuse 23 mit der gleichen Form und den gleichen Außenabmessungen und der gleichen Steckverbindung wie die Wärmetauscher befestigt, in dem technische Mittel insbesondere die elektrischen und/oder Heiz- und/oder Kühlkreislauf-Anschlüsse, die Elektrik, die Elektronik und vorzugsweise ein Stellantrieb für die Lamellen der Ventile angeordnet sind.On one side of the series of heat exchangers 1 or between them is preferably a tubular housing 23 with the same shape and the same outer dimensions and the same connector as the heat exchangers attached, in the technical means in particular the electrical and / or heating and / or cooling circuit -Connections, the electrical system, the electronics and preferably an actuator for the fins of the valves are arranged.

Statt einer Anordnung nebeneinander können die einzelnen Wärmetauscher 1 einer Konvektoreinheit auch in anderer Weise gruppiert werden. Ferner muss die Wand 2 jedes Wärmetauschers nicht unbedingt kreisförmig sein, sondern es ist auch ein ovaler Querschnitt möglich. Instead of a side-by-side arrangement, the individual heat exchangers 1 of a convector unit can also be grouped in a different way. Furthermore, the wall 2 of each heat exchanger does not necessarily have to be circular, but an oval cross-section is also possible.
