  • the fluid flows into the first conduit 1211 through the communication cavity 138 of the connecting member 13, the bottom opening 1115, the throttle opening 1114 and the peripheral opening 1113 after it flows in from the communication passage 103 so as to exchange heat with the fluid in the adjacent inter-sheets passage 1212.
  • a manufacturing method for the heat exchange apparatus shown in FIG. 12 is provided according to the embodiment of the present application, which includes:
  • the manufacturing method further includes: provide a bottom pressing block 123, protrude part of the connecting member 13 into the first conduit 1211, arrange the flange portion 137 of the connecting member 13 between the bottom pressing block 123 and the sheet portion 121, and sealingly connect the connecting member 13 with the sheet portion 121 by the sealing member;
  • the manufacturing method does not need to weld the connecting member 13 to the core body member 12, and the assembly process of the connecting member 13 and the valve core member 12 is arranged after the welding of the core body member 12, which reduces the influence of various uncertain factors during the welding of the core body member 12 on the sealing between the connecting member 13 and the core body member 12, the process is simple and the manufacturing method is simple.
  • FIG. 14 it is a schematic partial cross-sectional view of another heat exchange apparatus. In order to show the structure more clearly, some reference numerals of the following structures may not be shown in FIG. 14 , which can make reference to FIG. 12 .
  • the matching mode between the connecting member 13 and the bottom section 1111 can refer to FIG. 12 .
  • the core body member 12 includes the bottom pressing block 123, and the bottom pressing block 123 is fixed to the sheet portion 121 by welding.
  • the connecting member 13 includes the first end portion 134 and the second end portion 135, the first end portion 134 of the connecting member 13 is arranged sealed to the bottom section 1111 (referring to FIG. 12 ), the second end portion 135 of the connecting member 13 protrudes into the bottom pressing block 123, the second end portion 135 of the connecting member 13 includes the second groove 1117, the heat exchange apparatus includes the second sealing member 15, and the second sealing member 15 is arranged in the second groove 1117 so as to seal the outer wall of the connecting member 13 to the inner wall of the bottom pressing block 123.
