Definitions

  • the invention relates to a heat exchanger for motor vehicles with the features of the preamble of claim 1. Furthermore, the invention relates to a cooling module for motor vehicles.
  • a heat exchanger is out of the DE 30 17 701 known.
  • the collection spaces are formed by means disposed in the plates breakthroughs which are formed at the opposite ends of the plates.
  • Each forming a tube two plates are stacked with their breakthroughs aligned.
  • the heat exchange fins are inserted in the spaces between the tubes. There then the cooling air flows freely through.
  • Another heat exchanger whose tubes are also formed from two plates, is from the DE 44 07 080A1 known.
  • This heat exchanger could probably be used as a charge air cooler.
  • he belongs to a different genus, namely a genus in which the tubes forming plate stack is arranged in a housing. The charge air flows there on one side of the housing, is in heat exchange with a cooling liquid flowing in the tubes and leaves the housing on the opposite side.
  • Another heat exchanger was in the DE 40 12 046A1 shown and described.
  • This heat exchanger belongs to the type in which cooling air can flow freely through the heat exchange fins. There, the ends of flat tubes were bent and placed directly against each other. Collecting boxes can be connected at the ends. The bending area or the connection area of the collecting tanks is also not available there for heat exchange.
  • JP 2003 161589 A and JP 62-084842 A are presented so-called ring cooler.
  • the heat exchanger for aircraft applications is shown and described.
  • the heat exchanger is attached to the wings or the fuselage of the aircraft so that the plenums or the collection boxes are hidden in niches and the flat tubes can be acted upon by the air flow.
  • the flat tubes consist of at least four parts. Heat exchange ribs between the flat tubes are not provided there.
  • the object of the invention is to provide a heat exchanger of the type described in the preamble of claim 1 comparatively larger heat exchanging surfaces.
  • both ends of the tubes open in the long side remote from the inflow side, which is thus facing away from the inflowing cooling air, it is possible to form the entire or at least a larger of the cooling air flowed surface of the heat exchanger as a heat exchanging surface, whereby the heat exchanging surface is therefore comparatively enlarged.
  • the enlargement of the heat exchanging surfaces could be realized.
  • the very last ends of the plates or tubes are slightly enlarged in cross-section and lie with their narrow sides against each other. Therefore, the headers can be installed without the provision of a tube bottom. If the cross-sectional enlargement of the very last ends is dispensed with, tube sheets must be fitted to the ends of the pipes to which the header boxes are to be attached.
  • Two plates each are placed with their edges together to form a tube.
  • the plates can be identical. Both plates then have a raised edge on which the two plates abut each other to form the tube and are connected. However, it is also possible to make a plate about level, so without forming erect edge, and to provide the other plate with a raised edge.
  • the ends of the tubes or of the plates each have an angled contour in order to be able to open in the longitudinal side remote from the inflow side.
  • the angled contour piece can be kept quite short - just long enough to connect collection boxes.
  • heat exchange ribs or other heat exchange promoting elements are inserted. Also in the area with the angled contour such elements are arranged.
  • connection of the plates and the connection of the plates or the tubes with the heat exchange ribs is preferably carried out by means of soldering.
  • the collection boxes can be made of plastic or metal.
  • the heat exchanger shown in the embodiments is used in a motor vehicle. It can be either a cooling liquid cooler exposed to cooling air or else a charge air cooler. Other uses, for example as applied with cooling air oil cooler, are also very well conceivable.
  • the Indian Fig. 1 in a perspective view shown heat exchanger is arranged in front of the vehicle. He has a comparatively large inflow area A, which is acted upon by cooling air.
  • both ends 4a and 4b of the plates 1a, 1b and of the tubes 1 are located on the longitudinal side L2 of the plates 1a, 1b or of the tubes 1 which is remote from the upstream side A. Therefore, it is also possible to use approximately U-shaped plates 1a , 1b are spoken, which are used there.
  • the collecting boxes 30 are either made of plastic and are mechanically attached to the ends 4a and 4b or they are, like the tubes 1 and arranged between the tubes 1 heat exchange ribs 2 made of a metal. Here, aluminum or a suitable aluminum alloy is the preferred choice.
  • the plates 1a, 1b have a raised edge 10 and are each assembled into a tube 1 to be soldered (later) at their erect edges.
  • the Fig. 2 shows a piece of the tube with one end 4 and the Fig. 3 shows a piece of a plate 1a.
  • the plates 1a and 1b are identical.
  • the tubes 1 are in a conventional manner with the Heat exchange ribs 2 assembled.
  • heat exchange ribs 2 are also used or arranged in the plate areas 5 , which are angled and lead to the collecting boxes 30 .
  • the resulting heat exchanger block is subjected to a brazing process and thereby combined into a compact block.
  • the Fig. 4 indicates that in this embodiment, 1 inserts 20 are also within the tubes.
  • the inner inserts 20 do not have to go over the entire tube length. You can also have a distance to the narrow sides S.
  • the aforementioned longitudinal sides L1, L2 preferably extend in the transverse direction of the motor vehicle, not shown. However, they could also run in the vertical direction of the motor vehicle.
  • FIGS. 9, 10 and 11 show views of the heat exchanger from above or below, which also have enlarged heat exchanging surfaces. These are schematic representations.
  • the representation according to the Fig. 9 has approximately Z-shaped plates 1a and 1b, each forming a pipe. 1
  • the left-hand end 4a of the plates 1a, 1b or the tubes 1 opens into the longitudinal side L2 remote from the inflow side A.
  • the other in the image right end 4b opens in the inflow side A and in the longitudinal side L1.
  • the Fig. 10 could be considered as a representation having somewhat larger heat exchanging areas than that according to US Pat Fig. 9 ,
  • There are L-shaped plates 1a, 1b and tubes 1 are used.
  • the image in the left end 4a is located as in the Fig. 9 in the long side L2 remote from the upstream side A.
  • the other end 4b is located in the narrow side S remote from the left end 4a .
  • the collecting box 30 arranged there is designed to be particularly flat in order not to have to significantly limit the size of the inflow side A.
  • a further illustration, not shown, has a collection box 30 not arranged on the remote narrow side S but on the narrow side S lying near.
  • the pipes 1 have a flow separation in the longitudinal direction, so that the charge air flowing in, for example, to the narrow side S and can flow back from there.
  • the representation according to Fig. 11 is similar to the one after the Fig. 1 - 6 , However, it shows in contrast to a convex contour of the long sides L1 and L2. Again, the entire surface of the plates 1a, 1b can be formed as a heat exchanging surface. Compared to known ring coolers in which the Flat tubes are bent over their narrow sides S, which is still difficult to manufacture, especially when there are inserts in the flat tubes, the producibility was improved or facilitated by the proposal.
  • the longitudinal sides L1, L2 towards the ends 4a, 4b slightly apart and seemingly increase the cross section thereof. This is not preferred but due to the representation by "autoforming".
  • the longitudinal sides L1 and L2 provided with the convex contour run parallel to one another, ie also at the ends 4a, 4b.
  • the headers 30 at the ends 4a, 4b were merely indicated.
  • the Fig. 7 now shows a view of the inflow side of a cooling module in which the heat exchanger from the Fig. 1 - 6 located.
  • the heat exchanger is a charge air cooler LLK.
  • the inflow side of the cooling module is also the upstream side of the heat exchanger.
  • the heat exchanger was placed in the lower part of the cooling module. Above this there is, for example, a cooling liquid cooler and other components belonging to the cooling module.
  • the Figure 7 makes the enlarged heat exchanging surface of the intercooler LLK compared to the above arrangeddeckenkeitkühler particularly clear.
  • the Fig. 8 shows the cooling module from the back.
  • the intake and exhaust ports of the intercooler LLK can be seen on the left and right, below.
  • the total area is bordered by a fan hood V , on which a fan is arranged to suck cooling air through the cooling module.
