。Therefore, as a heat exchanger that solves the above problem, it has an aluminum cylindrical combustion shell and a plurality of refrigerant passages inside.
It has also been proposed that the refrigerant passage member is provided with an arcuate tubular refrigerant passage member made of aluminum and brazed to the combustion cylinder in close contact with the outer peripheral surface of the combustion cylinder so that the refrigerant passage extends in the circumferential direction or in the axial direction of the combustion cylinder. (Utility Model Application Publication No. 63-97066). Although this heat exchanger can solve the problems of the conventional heat exchanger described above, it is thought that the following problems will occur. In other words, since the combustion shell is cylindrical and the tubular refrigerant passage member is arcuate, manufacturing such a heat exchanger requires many jigs with complex structures, and There is a problem in that the work of fixing the combustion shell and the refrigerant passage member is troublesome. In addition, it is not possible to completely bring the combustion shell and refrigerant passage member into close contact when fixing with a jig, and as a result, a gap may be formed between the outer peripheral surface of the combustion shell and the refrigerant passage member in the manufactured heat exchanger. It is unavoidable. The existence of the gap reduces the efficiency of heat transfer from the combustion shell to the refrigerant passage member.

ガスの流出が防止される。Function: According to the heat exchanger of the present invention, since the flat tubular refrigerant passage member is brazed to the outer surface of the heat transfer partition wall that closes the opening at the other end of the combustion barrel, the brazing of both members is reliably performed. High-temperature combustion exhaust gas from the burner enters the upper high-temperature gas flow regulating member between the upper and lower high-temperature gas flow regulating members, and flows upward therein. Further, the gas enters the lower hot gas flow regulating member from between the upper and lower high temperature gas flow regulating members and flows downward therein. The heat of the exhaust gas is transmitted to the refrigerant flowing in the refrigerant passage of the refrigerant passage member through the heat transfer partition wall and the peripheral wall of the refrigerant passage member, and this refrigerant is heated and vaporized by the combustion heat of the burner. At this time, the gas leak prevention portion of the fixing member and the wing portion integrally provided on the gas leak prevention portion prevent gas from flowing out from between the upper and lower high temperature gas flow regulating members to both left and right sides.
