Definitions

  • the invention relates to a heat exchanger for a motor vehicle with one composed of flat tubes and corrugated fins Ribs / tube block, with all tube ends of the flat tubes expanded for a flat and flush abutment are, with two collection boxes, each to the opposite End faces of the fins / tube block on the tube ends are placed, the collecting boxes flush the pipe ends finally overlap, as well as with two side parts that extend at least over the length of the fins / tube block and on opposite sides on the fins / tube block connect.
  • Such a heat exchanger is in the unpublished DE 195 43 986.4.
  • the heat exchanger has a fin / tube block made up of a variety of Flat tubes and corrugated fins arranged between them is.
  • the tube ends of the flat tubes are on both End faces of the fins / tube block on a rectangular free cross section expanded so that the respectively formed Long sides of the tube ends of adjacent flat tubes and lie flush with each other, so that both End faces of the fins / tube block each have a tube end package results.
  • This tube end package is on both faces of each overlapped a collection box that is dimensioned in this way is that it is flush with the narrow sides the pipe ends can be put on.
  • On the sides of the fins / tube block are arranged side panels that either outside or inside the closed side areas of the collection boxes are attachable.
  • the object of the invention is to provide a heat exchanger at the beginning mentioned type to create a simplified structure and consequently has a simplified production.
  • each collection box too its - in relation to the longitudinal axis - side areas open is designed, and that the side parts on their opposite End faces to the header boxes which have the open side areas of the collection boxes close.
  • the invention Solution creates the conditions for a machine Assembling the heat exchanger, creating a significant cost-effective production is achieved. Also through the simple construction of the collection boxes with open forehead areas the manufacturing effort for the heat exchanger is reduced. By attaching the side parts to the ribs / tube block becomes the functional one in a simple way Closing the side areas of the collection boxes achieved.
  • This configuration is special advantageous if the collection boxes like the fins / pipe block and the side parts are also made of metal and in a joint soldering process with the fins / tube block and the side parts are soldered.
  • the collection boxes, the side parts and the ribs / tube block at least solder-plated in their areas to be joined together.
  • the collection boxes, the side parts and the ribs / pipe block are put together before the actual soldering process, the side parts using straps or other clamping devices on the sides of the fins / tube block are held. In this merged, however not yet soldered assembly close the end sections of the side parts already the side areas of the collection boxes.
  • the fact that the inner contour of the collection boxes over a certain axial length is identical the side parts and thus also the end sections of the side parts by a certain amount during the soldering process Axial amount towards the center of the fins / tube block move without the flush closure in the area of the collection boxes get lost.
  • the side areas each collecting box securing elements for axial support - related to the longitudinal axis of each collection box - des inserted end section assigned to each side part.
  • These securing elements are particularly advantageous to hold the individual components of the heat exchanger assembly together before a fixed connection by a corresponding one Soldering process.
  • the securing elements thus serve a cohesion of the structural unit from the collecting boxes, the fins / tube block and the side parts in a pre-assembly stage and especially before the actual soldering process to achieve.
  • each collection box molded support tabs provided by a deformation force from one with the inner contour of the side area aligned release position in a respective End section axially engaging securing position are transferable. This is a particularly simple and reliable Design by the molding of the Support tabs on the collection box does not require any additional components.
  • the end sections of the side parts at the level of the safety elements interlock.
  • the securing elements and the guide parts are coordinated so that in addition to an axial securing of the side parts on the collecting boxes the collection boxes themselves against loosening in the longitudinal direction of the Ribs / tube block and thus in the longitudinal direction of the flat tubes are secured, which ensures a correct positioning all components of the heat exchanger to each other.

Between The two water boxes 1, 2 extend a fins / tube block 3, made up of a variety of parallel to each other extending flat tubes 5 and arranged between them Corrugated ribs 4 is composed. Both the water boxes 1, 2 and the fins / tube block are made of solder-plated Made of aluminum sheet.
  • the two water boxes 1, 2 are each as simple, U-like Profiles designed (Fig. 7), being both to the Tube ends 6 of the fins / tube block 3 towards them axial end faces - on a longitudinal axis L of each water tank 1, 2 related - are open.
  • the open ones End faces of each water box 1, 2 form side areas 10, the end profiles serving as end sections 9 are closed by side parts 7.
  • the side parts 7 as well their insertion into the side areas 10 of the water boxes 1 and 2 are described in more detail below.
  • the upper water tank 1 has an inlet connection 11 and one - in relation to the longitudinal axis L - axially offset Outlet port 12 provided laterally to corresponding Openings of the water box 1 are tightly attached.
  • a separation area 19 Partition unspecified inside the water tank 1 provided.
  • the Separation area 19 by arch-like, rib-shaped impressions formed on which there is a partition inside the water tank 1 can support.
  • the lower water tank 2 is also provided with a separation area 20, the analog rib-shaped Has impressions, but in the illustrated embodiment for the water box 2 no further function exhibit.
  • the side regions have 10 of each water box 1, 2 starting from its front edge to the middle of each water box 1 - in axial Seen in the direction of the longitudinal axis L - a constant inner contour on, with one leg of the U-like profile each side area 10 with a greater curvature to one Head side of the profile connects as the other leg.
  • the two end sections 9 of each side part 7 have a serving as the final contour on the outer contour that exactly to the Inner contour of the associated side area 10 of each water box 1, 2 is adapted.
  • Each end section 9 is as tongue-like sheet metal part made of aluminum, the symmetrical is angled to widen the pipe ends (Fig. 1).
  • each end section 9 At the outer edge of each end section 9 is a circumferential Provided flange 17 which is perpendicular to the End section 9 protrudes and the to the inner contour of the Side area 10 of each water box 1, 2 adapted final contour 12 of each end section 9 defined. Of the Contact flange 17 also serves to stiffen the end section 9. As can be seen from Fig. 1, the end sections 9 positioned on the two water boxes 1, 2 in such a way that they have the outer corrugated fin 4 on each side limit the fins / tube block 3 and at the respective Tube end 6 of the corresponding outer flat tube 5 abut.
