Definitions

  • the present invention relates to a heat exchanger, particularly a liquid-gas, liquid-liquid or gas-gas heat exchanger for motor-vehicle air-conditioning or engine-cooling systems, of the type including at least one header with a tube plate of polymeric material.
  • the hydraulic seal between the tube matrix of the exchanger and the tube plates is normally achieved by the expansion of the tubes in the corresponding holes in the plate or by the interposition of a gasket of elastomeric material having a plurality of holes with raised edges complementary to the holes in the tube plate.
  • the object of the present invention is to provide a heat exchanger which overcomes the said problems.
  • each hole in the tube plate has a sealing ring of elastomeric material which is integral with the tube plate and is adapted to ensure the hydraulic sealing of the header.
  • the sealing rings which are formed by co-moulding with the tube plate, achieve a saving in the final cost of the product (less elastomeric material is used, the implementation cost is lower, and the heat exchanger is easier to assemble).
  • each header has a cover of polymeric material which is welded to the tube plate, for example by ultrasonic mirror welding, or is fixed thereto either mechanically or by chemical welding.
  • a header for a water-air heat exchanger for installation in the air-conditioning system of a motor vehicle is generally indicated 10.
  • the header 10 has a tube plate 12 of polymeric material, to the periphery whereof a- convex cover 14, also of polymeric material, is welded by ultrasonic or hot-blade welding.
  • the tube plate 12 has a plurality of holes 16 (which may be of various shapes, circular, eliptical, etc.) for the passage of tubes T of the exchanger.
  • a sheet 17 of elastomeric material is co-moulded on the face of the tube plate which faces the cover 14 and defines a plurality of sealing rings 18 in correspondence with the holes 16.
  • rings 19 of elastomeric material are co-moulded with the tube plate in correspondence with the through-holes 16.
  • Each sealing ring 18 or 19 has a respective annular portion 18a or 19a with an outside diameter substantially corresponding to the diameter of the corresponding hole 13 in the tube plate and an inside diameter approximately equal to the outside diameter of a metal tube T to be inserted sealingly in the hole 16.
  • the material used for the manufacture of the cover 14 of the tube plate 12 is a thermoplastics technopolymer (for example polyamide, polypropylene, etc.), or an injectable thermosetting polymer, whilst a thermoplastics elastomer may, to advantage, be used for the sealing rings 18 and 19.
  • a thermoplastics technopolymer for example polyamide, polypropylene, etc.
  • an injectable thermosetting polymer whilst a thermoplastics elastomer may, to advantage, be used for the sealing rings 18 and 19.
