Definitions

  • the invention relates to a radiator according to the preamble of claim 1.
  • a radiator is known from EP-A-0 350 528.
  • the first spars of the holding frame each consist of an inner band in contact with the slats, a parallel, spaced-apart, rigid outer rail and a wave spring arranged in between, which is supported on the outer rail and against the inner band presses the reversal points of the adjacent slats.
  • the invention has for its object to provide a radiator of the type mentioned, which ensures a sufficient and large area pressure of the fins on the heat-emitting elements and which is easy to set up and install.
  • the invention differs from the above-mentioned prior art mainly by the novel design of the first spars. Instead of a three-part arrangement, the invention realizes a one-part arrangement for each respective spar, which eliminates two manufacturing processes and facilitates assembly. In addition, good surface contact and thus good heat extraction are achieved even with dimensional tolerances in the PTC elements.
  • the rigidity of the bars can be increased by a suitable profile design, which provides that the outer legs of the bars are each bent inwards.
  • a rail of substantially M-shaped cross section can be arranged in the open cross section of each of the first spars, which rail is riveted or welded to the outer legs of the spar on its outer legs. This rail gives the spar a particularly high degree of rigidity that resists deflection.
  • the drawing shows a radiator from the side, where to see where electrical heating elements are, these are shown in section.
  • the radiator consists of a holding frame 1 made of first, longitudinal bars 2 and second, transverse bars 3.
  • the first and second bars 2 and 3 are connected to one another at their ends and thus span a plane.
  • the electrical heating elements 4, which are preferably PTC elements, and the heat-conducting elements 5 form a multilayer structure, which is clamped between the two opposing first bars 2 of the frame 1.
  • the pressure that presses the aforementioned elements together is applied by resilient bulges 6, which are formed on the first spars 2.
  • the force caused by these bulges is absorbed by the second frame bars 3.
  • the PTC elements 4 are each held in a plastic frame 7, which has a slightly smaller thickness than the PTC elements 4, and has windows or openings 8 in which the PTC elements 4 are held. At its longitudinal edges, the plastic frame 7 has raised edges 9, which prevent the heating elements 5 and the plastic frame 7 from sliding against one another.
  • the first, longitudinal spars 2 of the frame 1 consist of an essentially U-shaped rail made of a resilient material, the legs of which are flat, the outer legs 11 being bent inwards.
  • the inwardly bent sections 12 of the outer legs 11 end tightly above a flat central leg 13.
  • the inwardly bent sections 12 give the spar 2 great rigidity.
  • the center leg 13 is extended at both ends (only one end is shown in FIG. 4) by a flag 10, from which a resilient tongue 14 is released, the free end of which points towards the spar 2.
  • a cross-sectionally M-shaped rail 15 is inserted into the free interior of the cross-section U-shaped spar 2, the outer legs of which several points 16 are riveted or welded to the outer legs 11 of the spar 2. This construction also ensures a desired rigidity for the spar 2.
  • FIG. 5 also shows two metal strips 31 which are welded to the outer leg 11 in the end region of the U-shaped spar 2. They extend to the corresponding outer legs of the other spar 2, which is not shown in FIG. 5, and they are welded to it under mechanical prestressing of the overall arrangement in order to absorb the spring forces produced by the bulges 6. The second spars 3 can then be pushed onto the arrangement held together by the sheet metal strips largely without tension.
  • the flag 10 is inserted into a cavity in the adjacent second spar 3, and the free end of its tongue 14 is locked behind a shoulder 17 which is formed on a section of the second spar 3 is that overlaps the flag 10.
  • a nose 18 extends into the free space between the side legs of the first spar 2, which presses on the middle leg 13 and thus presses the bulges 6 onto the adjacent heat-conducting element 5.
  • the nose 18 has on its underside a guide channel for the tongue 14 which merges into a ramp 20 which leads to the shoulder 17.
  • FIG. 7 shows the arrangement of FIGS. 1 and 6 from above in the assembled state. You can see the nose 18 on the second spar 3, which engages between the side legs 11 of the first spar 2 and thereby pushes the inner portions 12 away from it somewhat laterally and which presses on the center leg 13.
  • the detail in Fig. 8 shows that the apexes on the reversal areas 21 of the slat band are as flat as possible. For this purpose, it can be advantageous if the apex area is designed to be slightly curved in order to ensure that the lamellar strip abuts against an adjacent sheet metal strip 23 under pressure.
  • FIG. 9 shows a preferred embodiment of a heat-conducting element.
  • This consists of two metal strips 23 and 24, each of which is angled twice at one end and which are arranged symmetrically with respect to one another, so that they enclose an approximately rectangular space in a plane-parallel area of the metal strips 23 and 24, in which there is a slat strip 26, which is carried out, for example, in the manner of FIG. 8.
  • the two metal strips 23 and 24 are connected at their abutting sections with rivets or the like, which are symbolically represented here by 27. At one end, a terminal lug 28 is riveted at the same time.
  • FIG. 10a and 10b show details of the riveting of the sheet metal strips 23 and 24 of the heat-conducting element according to FIG. 9. It can be seen in FIG. 10a that on one sheet metal strip 23 a rivet sleeve 29 is integrally formed by deep drawing, which has a suitable bore in the penetrates another sheet metal strip 24 and is jammed by widening its free end in the bore on the sheet metal strip 24. A comparable connection of the metal strips 23 and 24 is also provided on the other side, as shown in FIG.
  • the contact terminal lug 28 being provided in a comparable manner with an integrally formed rivet sleeve 30 which is inserted through the rivet sleeve 29 and flanged at its end , in order thus the connecting lug 28 on the Determine heat conducting element and at the same time establish electrical contact.
  • the sheet metal strips 23 and 24 can be slightly flanged up at their edges, as is shown by way of example in the sectional illustration in FIG. 11, in order to prevent the slat strip 26 from slipping sideways.
  • the heat-conducting elements 5 are in direct contact with the electrical heating elements 4.
  • the heat therefore runs from the electrical heating elements 4 through one of the metal strips 23 and 24 to the adjacent lamella strip, which thus absorbs the heat and can release it into the surrounding air.
  • two such heat-conducting elements 5 can be arranged between two adjacent levels of heating elements. Since the heat-conducting elements 5 contact the PTC elements 4 directly, they can be used for their power supply, for which purpose the connection lug 28 is provided. It can be seen in FIG. 1 that with the aid of two such heat-conducting elements 5 a group of heating elements 4 can be supplied with current.
  • the connecting lugs 28 extend through openings 29a in the second spars 30, which are made of an electrically insulating material, in particular plastic material.
  • the heating elements 5 can, as FIG. 9 clearly shows, be assembled into prefabricated units, and these units then only need to be stacked with the heating elements 4 held by the plastic frames 7 and each other and with the first bars 1, as shown in FIG. 1 shows, and then the lateral second bars 3 are pushed on from the side, their lugs 18 engaging in the spaces between the side legs 11 of the bars 2. It is understood that for this purpose the stack of spars, Heating elements and heat-conducting elements must be compressed so that the lugs 18 can be easily brought into position. When pushed together, the tongues 14 lock behind the shoulders 17 in the spars 3 and secure the arrangement in their position. None needs to be soldered, riveted or screwed for assembly.
  • FIGS. 12 and 13 Alternative embodiments for the first spars 2 are shown in FIGS. 12 and 13.
  • Fig. 12 shows the formation of the side legs of the spars with an upper bead-shaped edge
  • Fig. 13 shows an embodiment in which the inner portions 12 of the side legs 11 run approximately parallel to the outer portions of the side legs 11.
  • Fig. 14 shows an M-shaped rail for use between the outer legs of the cross-sectionally U-shaped spars 2 according to the type of Fig. 5, wherein the connecting leg 32 between the two outer legs 33 of the rail 15 is largely flat and a longitudinal one in the middle Has bead 34.
  • This rail 15 is also, as shown in FIG. 5, to be fixed to the associated spar 2 by means of welding spots 16.
  • the lamellar strip 26 is insulated from the adjacent metal strips 23 (or 24) by an insulating film 35, for example made of Kapton.
  • the plastic frame 7 holding the electric heating elements 4 has very strongly raised edges which at least largely cover the edges of the metal strips 23 so that they form a protection against accidental contact, so that the radiator equipped in this way is touched with the hands can without touching live parts.
  • 16 shows an embodiment of the invention in which the space between two adjacent metal strips 23 and 24 is filled on the outside by a casting compound 36, with which the electrical heating elements 4 are protected against environmental influences, in particular against splash water.
  • Another modification possibility is to dispense with the metal strips 23 and 24 for holding the lamella strips 26. These then abut the bulges 6 and, if necessary, each other.
  • the electrical heating elements can be contacted by means of separate sheet metal strips which are arranged between the lamella strips and the heating elements and are provided with connecting lugs which lead to the outside, comparable to the connecting lugs 28.
