Description

Technical field

The invention relates to a radiator for space heating with extruded Profiles made of aluminum and its alloys according to the preamble of claim 1.

State of the art

In the radiator known from DE - C - 24 12 735 there are at the top and at the bottom Front of the lined up vertical links, with through holes are provided, each containing a cross channel Horizontal links fastened with a screw sleeve, with a connecting piece is formed.

Each upper connection piece is screwed in on both sides upper screw sleeve with left-right thread formed by the lower horizontal member facing end of the associated vertical member is rotatable here. The lower connection piece of each vertical link is in contrast from a screw sleeve screwed into this with a unidirectional Thread formed, the projecting head of the lower horizontal link clamped against the vertical link.

To brace the vertical links with the lower horizontal link are in this provided the through holes opposite the sealed after inserting and tightening the associated screw sleeve will.

The radiators according to this prior art have the particular disadvantage on that at each junction of the connecting piece between the Vertical links and the upper and lower horizontal link threads both can be cut into the vertical links as well as the horizontal links must, which are essential for bracing the individual parts.

Another disadvantage is that on the lower horizontal link existing additional openings Possibilities for leaks from heating media form.

In addition, there are two for each of the vertical links used Screw sleeves or sealants required, creating a high overall Manufacturing and assembly costs per radiator is required.

From DE-C-36 03 230, DE-A-23 06 256 or DE-U-73 39 310 are further solutions of several vertical elements Radiators known with water pipes for supply or discharge of the heating medium can be plugged together and their connection of vertical and Horizontal link, for example, via glued-in connecting pieces is achieved.

FR A-2298076, which forms the closest prior art, describes the modular construction of a radiator using annular seals to seal the connection between the finned tubes and the cross-pieces as well as the use of tie rods to ensure the cohesion of those to be connected Elements.

Such annular sealing elements are not suitable for sealing elongated profile cross-sections of vertical and horizontal profiles with different flow cross-sections.

From FR-A-2504667 is a solution of a rectangular cross section Heating channel with increasing opening cross-section of the through openings known from sealing elements.

The disadvantage of this solution is that it is only for heat exchangers with dimensions of over 5 m and a width of up to 2 m and one in a ratio of 25 small thickness can be used, primarily from the Plastic material exist. The proposed sealing elements are also only suitable for constructive training for the purpose of joining, Welding or gluing between the double-walled plate and the To bring about the main body transverse channel.

The disadvantage of these solutions is that the front of these radiators essentially from secondary heating surfaces, i.e. Heating surfaces over webs with the pipe cross section leading the heating medium are formed becomes. This results in different surface temperatures in the Front, which have a very negative influence on the energy output through thermal radiation.

Overall, other disadvantages of these solutions are those that are technologically necessary and complex welding, adhesive and screw connections between the Vertical and horizontal links.

Presentation of the invention

The present invention is therefore based on the object of a radiator to create the type of radiant heat improved, i.e. high surface temperatures equal to the heating medium on the entire radiation surface, its manufacture and Assembly is very simple and its outer surfaces before assembly are surface treated.

This object is achieved by the features of claim 1.

An advantageous embodiment of the invention is characterized by the features of claim 2 reached.

Best way to carry out the invention

Using an exemplary embodiment of the invention, an optimal design the invention according to the drawings listed above.

In the drawing (Fig.1) is a section of a single-row radiator shown, which consists of a number of vertical members 1. The Vertical members 1 are essentially of the same width and each have a radiator exactly the same length. As can be seen from FIGS. 1 and 2 is, the vertical members 1 consist of an extruded profile Made of aluminum or a light metal alloy with over their entire Length of constant dimensions.

The vertical member 1 has at least one in its interior Wall of the vertical member formed heating channel 2, which is preferably is separated by a web 3 (Fig. 3) into two equal channel parts.

The channel parts form an elongated cross section and are semicircular Rounding on both sides.

On the respective outer narrow end faces of the essentially one Rectangular cross-section vertical member 1 is on one side a recess 4 is provided, which is of the same shape on the other end face Projection 5 is arranged opposite.

If several vertical links 1 are lined up in the same direction, it can thus a stable and smooth radiation surface similar to a tongue and groove connection 6 of a radiator are formed.

On the rear side opposite the radiation surface 6 are the same moderate distance to each other and parallel to the axis and perpendicular to the wall of the vertical member 1 arranged ribs 7. The ribs 7 serve on the one hand the vertical stability of the vertical members 1 and on the other hand as a secondary heating surface.

At the top end of the vertical links 1 according to the drawing is a Horizontal member 8 arranged, which is provided with a horizontal channel 9 is. In the area of the vertical heating channels 2 of the respective lined up Vertical links 1 are 8 vertical channels 10 in the horizontal link introduced that a connection between the horizontal channel 9 and the Form heating channels 2. At the respective contact surfaces of the horizontal link 8 and the vertical members 1 are seals 11 with through openings 12 arranged partially in the vertical channel 10 and partially plug in heating channel 2 and adapted to the shape of channels 2 and 10 are.

Approximately in the middle of each seal 11 is a collar 13 as an assembly aid and additional sealing surface between each profile tube member 1 and the Profile body 8 provided.

It is to complete a radiator of a certain size required that the upper horizontal member 8, for example the Flow of the heating medium ensures a return for the heating medium assigned. This return is identical to the horizontal member 8 and a mirror image on the opposite lower side of the vertical links 1 arranged.

Because of the same, only reversed arrangement, this is not described in detail.

The horizontal member 8 has on its vertical members 1 facing Side with a recess 14 extending in the axial direction a front wall 15 and a rear wall 16. The recess 14 is designed to match the thickness of the body of the vertical links 1 and overlaps it in such a way that sufficient clamping bracket of the horizontal member 8 is ensured.

Furthermore, the recess 14 is arranged so that the drawing lower openings of the vertical channels 10 in the middle of their groove bottom come to lie. The horizontal link is made by means of a pin connection 18 8 with the aid of the seals 11 with the number of vertical links 1 attached to the respective end faces.

A free cut 19 of the ribs 7 ensures that the rear wall 16 the recess 14 is exposed along the horizontal member 8 (see FIG. 3).

3 are in the region of the webs of each vertical member 1 in Connection to the walls 14 and 15, the pin connections 18 as Taper pin connections carried out. Ensure these pin connections a stable safeguard against lifting off with relatively little effort the horizontal links 8 from the vertical links 1.

As can also be seen from FIGS. 2 and 3, the seals have 11 has a number of through holes 12, from seal to seal have different diameters.

It is intended to choose the diameter of the through opening 12 in this way and arrange that in the heating channels 2 of all vertical members 1 approximately same volume flows occur. The diameters increase in the direction of Flow of the heating medium and can finally at the end of the radiator correspond almost to the clear width of channels 2 and 10. Through this Measure is achieved that a homogeneous heat distribution over the heating ducts 2 belonging to the radiator take place, with which a uniform Heating of the entire radiation surface 6 is achieved.

Standard fittings and sealing plugs are used to complete the radiators to the provided as flow or return for the heating medium Connections on the horizontal member 8 provided by appropriate Threaded connections are attached.

In addition to the single-row radiator variant shown, there are also two or Multi-row radiators put together by the individual Radiators by appropriate elements that convey the heating medium be connected to each other.

Industrial applicability

Starting from the arrangement according to the invention, which includes an elongated cross section of the heating duct, the outer surface of which simultaneously forms the radiation surface, a direct heat transfer from the heating medium into the heating duct can take place on the radiation surface.
This leads to a faster release of radiation energy over the entire surface of the plate, since the radiation surface of the radiator corresponds to the temperature of the heating medium.

However, this solution not only has advantages in terms of heat transfer, but also advantages in terms of simplicity of the concerned Building for space heating. The manufacture of such Radiators are possible through simple and inexpensive joining processes. Due to the technological elimination of welding, the use Already surface-treated, extruded light metal profiles enables a very complex surface treatment of the avoid complete radiator.

Such constructed radiators offer in terms of their application several positive effects, such as the high proportion of radiant heat in the total amount of heat given off by the radiator, the high thermodynamic Efficiency through the uniform surface temperature, as well as a high flexibility of the radiators in terms of architecture favorable design and execution. Among other things, because of the high Heat radiation share very cheap solutions, for example for find targeted heating of workplaces, bathrooms, stairwells.
