Definitions

  • a method for manufacturing a stacking-type, multi-flow, heat exchanger comprising a plurality of heat transfer tubes and a plurality of outer fins, which are stacked alternatively, also is provided.
  • Each heat transfer tube is formed by connecting a pair of tube plates to form a fluid passage in each heat transfer tube.
  • the method comprises the steps of forming a hole through each of the pair of tube plates, positioning the pair of tube plates, so that the holes of the pair of tube plates are aligned, and elongating or raising a portion of the pair of tube plates substantially simultaneously at a position at which the holes are aligned for fixing the pair of tube plates to each other.
  • diameters of tip portions of raised portions, formed by the step of elongating are enlarged.
  • the number of types of tube plates may be reduced.
  • the efficiency of assembling a heat transfer tube when fixing a pair of tube plates to each other may be significantly increased.
  • Inlet pipe 9 for introducing a heat exchanging fluid (e.g. , a refrigerant) into heat exchanger 1 is connected to tank portion 7a of tank 7.
  • Outlet pipe 10 for discharging fluid from heat exchanger 1 is connected to tank portion 7b of tank 7.
  • the fluid flows in a predetermined fluid passage formed in heat exchanger 1, and the heat is exchanged between the flowing fluid and outside air passing through heat exchanger 1.
  • a stacking-type, multi-flow, heat exchanger, according to the present invention, is suitable as an evaporator for use in an air conditioning system for vehicles.
  • tube plates are depicted for a heat transfer tube used in a stacking-type, multi-flow, heat exchanger, according to an embodiment of the present invention.
  • a brazing material may be clad beforehand on front and back surfaces of tube plates depicted in Figs. 9-11 , and a flux for brazing may be applied uniformly on the front and back surfaces of the tube plates. Therefore, by assembling respective members of stacking-type, multi-flow, heat exchanger 1 and brazing them together in a furnace, a pair of tube plates and other members may be brazed to each other substantially at the same time.
  • a tube plate 30 (e.g. , a communication plate) depicted in Fig. 9
  • cup portions 31, 32, 33, and 34 protrude outward from plate 30 and are formed on the end portions in the longitudinal direction of the tube plate.
  • Communication holes 35, 36, 37, and 38 are provided through portions 31, 32, 33, and 34.
  • a communication path 55 is formed between cup portions 31 and 33, and cup portions 31 and 33 communicate with each other through communication path 55.
  • Protruded portions 39 and 40 extend in the longitudinal direction of tube plate 30 and are formed on the tube plate 30 to form fluid passages in heat transfer tube 2.
  • Heat transfer tube 2 may be formed by fixing a pair of such tube plates 30 to each other and fixing ( e.g. , brazing) them to each other.
  • the diameters of the tip portions of raised portions 45 and 46 may be enlarged or expanded in order to secure a pair of tube plates 30 more strongly.
  • a punch 47 for enlarging the diameter of or extending the tip portion of a raised portion is inserted into raised portions 45 and 46, and the diameters of the tip portions of raised portions 45 and 46 are enlarged by punch 47.
  • tube plates 30 may be secured to each other more strongly.
  • the condition of the end portions of the pair of tube plates 30, with the diameter-enlarged or extended, tip portions of raised portions 45 and 46, is depicted in Fig. 15.
  • tube plate 50 e.g. , a partition plate
  • tube plate 52 e.g. , a cup portion, independent-type plate
  • a pair of respective tube plates also may be fixed to each other in a similar manner to that described above.
  • the characteristics of stacking-type, multi-flow, heat exchangers, and the methods for manufacturing such heat exchangers, according to the present invention may be applied to any type of stacking-type, multi-flow, heat exchangers, wherein heat transfer tubes comprising a pair of tube plates and outer fins are stacked alternatively.
  • the present invention may be applied to stacking-type, multi-flow, heat exchangers used as evaporators in air conditioning systems for vehicles.
