<P>PROBLEM TO BE SOLVED: To provide a method of manufacturing a heat exchanger which can improve heat exchange efficiency by suitably transferring heat generated at a heat generation end part of a refrigeration device to a refrigerant. <P>SOLUTION: In the method of manufacturing the heat exchangers (21, 31) which are applied to the refrigeration device (10) generating heat at the heat generation end parts (11, 12), and exchange heat by transferring the generated heat to the refrigerant, a plurality of annular plate shaped heat transferring fin forming members (211, 311) are arranged on an outer circumferential surface of the heat generation end part so that the heat generation end part is relatively pressed in or brazed on insides of the respective heat transferring fin forming members while intervals between the heat transferring fin forming members are maintained to a predetermined interval. An outer circumferential region of the heat generation end part including the heat transferring fin forming members is covered with the cover member (212, 312) to form a flow channel R, which passes the refrigerant through the outer circumferential surface of the heat generation end part, in an outer circumference direction of the heat generation end part. <P>COPYRIGHT: (C)2012,JPO&INPIT |
