Definitions

  • the present invention relates to a heat exchanger and, more particularly, to a heat exchanger for a supercharger in an internal combustion engine.
  • a heat exchanger for a supercharger in an internal combustion engine used for cooling thermally-expanded intake air in order to increase charging efficiency of the intake air has been known, for example from Japanese Patent Publication No. 2002-286394, which discloses a heat exchanger having a pair of tanks, a plurality of tubes through which super-charged air passes, and fins for increasing heat discharge, brazed together in one unit.
  • the tank comprises a tank body and a core plate, and the tubes are inserted through insertion holes formed in the core plate.
  • inner fins are provided inside the tubes.
  • the inner fins are slid and inserted into the tubes, so that mutual contact may peel off brazing material and cause a defect in a brazed portion, leading to leakage of cooling water. Therefore, in a known structure, as shown in FIG. 14 , a tube 201 is formed by fitting one tube plate 201 a having inner fins 201 c placed thereon onto the other tube plate 201 b, and this tube 201 is inserted through a tube insertion hole 202 of the core plate.
  • the tube plates 201 a, 201 b fitted together may be opened in the bent portion, called “tati” in Japanese, bent in the U-shaped cross section, which has squared corners at the bottom side thereof, due to a draft angle at the time of press shaping or spring-back of the material.
  • tati in Japanese
  • a gap may be formed at the fitting section 201 f and may cause a brazing failure in the brazed portion.
  • a step 201 g is produced as a result of forming the fitting section 201 f, and this step increases the clearance between the tube 201 and the opening edge of the tube insertion hole 202 through which the tube 201 is inserted, leading to brazing failure.
  • a heat exchanger comprising: a plurality of tubes ( 104 ) inside of which a fluid passes; fins ( 105 ) which are joined to the outer surfaces of the tubes ( 104 ) and promote heat exchange between a fluid passing around the tubes ( 104 ) and the fluid passing through inside the tube ( 104 ); and tank sections ( 101 , 102 ) comprising core plates ( 101 b, 102 b ) having insertion holes ( 101 c, 102 c ) formed for the tubes ( 104 ) to be inserted therein and tank bodies ( 101 a, 102 a ) having the core plates joined thereto for distributing or collecting the fluid to be passed through the tubes;
  • the tube ( 104 ) comprises a first and a second tube plates ( 104 a, 104 b ) joined in opposition to each other and inner fins ( 109 ) disposed between the first and second tube plates ( 104 a, 104 b
  • the portion of a tube to be inserted into an insertion hole of the core plate may be formed to have generally the same shape as the periphery of the insertion hole so that brazing performance of the core plate and the tube can be improved.
  • the portions of the first and the second tube plates to be inserted into the insertion hole of the core plate have overlapping sections that overlap each other in the tube laminating direction. Therefore, by using a jig or the like to compress the overlapping sections in the tube laminating direction, the overlapping sections can be securely abutted to each other and brazing performance can be thereby improved.
  • the overlapping sections ( 104 c, 104 d ) are formed by attaching inner surfaces of the first tube plate ( 104 a ) and the second tube plate ( 104 b ) to each other. Therefore, in accordance with the second aspect, the tube plates can be formed in a shape that permits easy molding.
  • the overlapping sections ( 104 c, 104 d ) are fixed in calking by bending one of the first tube plate ( 104 a ) and the second tube plate ( 104 b ).
  • the overlapping sections can be more securely fixed and brazing performance can be further improved.
  • said overlapping sections are formed outside of said tube, with the end section of the tube in the longitudinal direction of said overlapping section abutted to said core plate.
  • positioning in the longitudinal direction of the tube relative to the core plate can be accomplished without requiring any jig.

  • Brazing paste specifically, brazing paste consisting of 75% copper, 15% tin, 5% nickel and 5% phosphor
  • brazing paste is applied to inner surfaces of the tube plates 104 a, 104 b for brazing the inner fins.
  • end edges bent in horizontal direction extend over the distance between the core plate 101 b and the core plate 102 b in the direction of the longitudinal axis.
  • the side edge is not bent in the horizontal direction, and the cross-section of these ends has generally the same shape as the periphery of the tube insertion holes 101 c, 102 c.
  • the tube is provisionally assembled with the first and the second tube plates disposed in opposition to each other such that the inner fins are sandwiched therebetween and respective overlapping sections overlap each other.
  • the provisionally assembled tubes and fins are laminated alternately, and each end of the tube is inserted into the tube insertion hole of the core plate, and the heat exchanging core section is provisionally assembled.
  • the provisionally assembled heat exchanging core section is compressed in the tube laminating direction by winding wire around it, and is heated in a furnace to be integrally brazed in one unit.

  • first tube plate 104 a and the second tube plate 104 b Since surfaces of the first tube plate 104 a and the second tube plate 104 b are abutted to each other in this manner, the first tube plate 104 a and the second tube plate 104 b can be stably positioned relative to each other so that good brazing performance can be achieved.
