Definitions

  • the invention relates to a device for connecting two heat exchangers for motor vehicles, consisting of from lower supports on the header of the first heat exchanger, into the lower one Struts of the second heat exchanger engage and upper spring clips, one leg of which upper struts of the second heat exchanger after pressing the second heat exchanger reaches around the first heat exchanger in order to hold both heat exchangers elastically to one another.
  • the device is known from DE 198 57 508 A1, from which the following invention is based.
  • the Advantage of the known device is the fact that the assembly and disassembly of the heat exchanger can be done easily and quickly, namely by inserting the lower struts of the second Heat exchanger in the lower supports of the first heat exchanger and pressing the upper struts the second heat exchanger until they snap into the upper spring clip.
  • the in the known The spring clip used in the document is a part that is specially made for the purpose a leg in a molded on the header of a heat exchanger sleeve is and with the other leg a vertical force on the upper and lower struts of the other heat exchanger, or on the cooling network of this heat exchanger itself.
  • the cooling network the heat exchanger consisting of relatively thin-walled flat tubes and corrugated fins, is therefore there under a certain tension, which is disadvantageous.
  • the object of the invention is to design the device so that vertical clamping forces on the cooling network can be avoided without the simple assembly and disassembly essential is affected.
  • the lower supports the lower struts in her Hold in the longitudinal direction under a torsional tension in the elastic area and the upper struts attached to the header of the second heat exchanger and to the header of the first heat exchanger attached holder of the legs of the spring clips includes such and are held together to maintain the torsional stress in the lower struts.
  • Vertical bracing forces on the cooling network of the heat exchangers are avoided because of the bracing forces be absorbed by the struts under torsional stress and by the Spring clips, the spring force of which maintains the torsional tension in the struts.
  • the second heat exchanger To both heat exchangers To connect, the second heat exchanger with its lower struts in the lower U - shaped support, the second heat exchanger being slightly inclined to the first heat exchanger. Then the second heat exchanger connects to the first heat exchanger pressed up, whereby both heat exchangers are approximately parallel to each other and the upper struts rest on the brackets in order to then be embraced by the spring clips.
  • both heat exchangers are approximately parallel to each other and the upper struts rest on the brackets in order to then be embraced by the spring clips.
  • the lower ones experience the pressing of the second heat exchanger onto the first heat exchanger Struts have a torsional tension created by connecting the top struts and brackets using the Spring clips is maintained.
  • the struts are practically clamped in the U-shaped supports, however, the mobility for material expansion caused by temperature change preserved.
  • Claim 2 describes an advantageous embodiment of the holder, the upper struts and the spring clips. Thereafter it is provided that the upper struts have a slot into which one on the holder arranged pin engages. Furthermore, the spring clips have a straight and an approximately wave-shaped deformed leg to grasp the holder and strut. Because both legs of the one to be used Spring clips lie in one plane and encompass the strut and the holder together, the spring clips can be made simpler. The use of commercially available, standard This has made spring clips possible.
  • the holder has an approximately semicircular contour on its side facing away from the pin, so that the spring clip can encompass the holder with its wavy leg. At the end of wavy leg of the spring clip has the same an expansion, whereby the spring clip can be pushed over the semicircular contour of the holder without any tools can.
  • the header boxes of both heat exchangers are preferably made of aluminum. Furthermore, the Collection boxes of the first heat exchanger made of cast aluminum, the holder and the Supports are formed on the collection boxes.
  • the header boxes of the second heat exchanger are preferably made from a semi-finished aluminum product, for example from a tube, the struts be attached to these collecting boxes by soldering. The complete manufacture of the Aluminum heat exchangers ensure complete recycling and therefore complies with Demands for waste reduction.
  • Heat exchanger 1 is a heat exchanger 1, which is a charge air cooler of a motor vehicle, with a Heat exchanger 2, which is a condenser of the air conditioning system of the motor vehicle, connected.
  • the cooling air flows through the cooling network 3, 4 of both heat exchangers 1 and 2.
  • the header boxes 5 of the heat exchanger 1 are made of cast aluminum, so that the lower support 6 and the upper holder 7 are formed directly on a longitudinal wall 8 of the collecting boxes 5.
  • the collection boxes 9 des Heat exchanger 2 consist in principle of an aluminum tube, which is closed at the top and bottom is and on one long side has slots in which the ends of the heat exchanger tubes open. This has not been shown because such designs are typical for capacitors.
  • the lower supports 6 are U-shaped, the two legs 6a, 6b of the U in Extend the longitudinal direction of the collecting boxes 5.
  • the inner leg 6a has a thickening 6c or a nose that allows the struts 10u of the heat exchanger 2 to be used, however first so that its cooling network 4 is still at an angle to the cooling network 3 of the heat exchanger 1 located.
  • struts 10u against the mentioned lugs 6c pressed and thereby subjected to a torsional stress or by clamping in the U - shaped Support 6 held.
  • the torsional stress in the strut 10u is relatively low, but it is sufficient to effect the clamping of the struts 10u between the legs 6a and 6b of the supports 6, so that both heat exchangers 1 and 2 are held together reliably in the lower area and still allow thermal expansion.
  • Fig. 2 shows clearly that one against the Arrow 15 protruding nose 6c to larger torsional stresses and thus clamping forces in the struts 10u would lead.
  • the spring clip 14 has a straight leg 14a and a wave-shaped Leg 14b.
  • the holder 7 has an L-shaped shape.
  • the holder 7 is on one leg Collection box 5 molded.
  • the pin 13 is arranged, on the rear
  • An approximately semicircular contour 7a is present at the end.
  • the semicircular contour 7a fits approximately with the Rounding in the wavy leg 14b together so that the holder 7 and strut 100th pushed spring clip 14 a secure connection between the under all operating conditions two heat exchangers 1.2, which can be quickly assembled and disassembled.
  • a bend 16 has been formed around the spring clip To be able to push 14 from above over holder 7 and strut 10o.
