不発明は、クロスフィンチューブ形の熱交換器において
、沸騰音を防止する伝熱管の構造に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a structure of a heat transfer tube that prevents boiling noise in a cross-fin tube type heat exchanger.
従来の熱交換器は、特開昭60−’l18’1号公報に

ダで固定している。A conventional heat exchanger is described in Japanese Patent Application Laid-open No. 118-1-1988, in which a hollow pipe-shaped insertion member (hereinafter referred to as A heat exchanger tube (called a heat exchanger tube) is installed in contact with the inside of the heat exchange pipe, and both layers are fixed with solder.
上記従来技術は、熱交換パイプと伝熱管の温度差により
上記両部材にか\る熱心力については配慮されておらず
、この熱応力により熱交換パイプが亀裂する問題があっ
た。The above-mentioned conventional technology does not take into account the stress exerted on the two members due to the temperature difference between the heat exchange pipe and the heat transfer tube, and there is a problem that the heat exchange pipe cracks due to this thermal stress.
本発明の目的は、熱交換パイプの亀裂を防止することに
ある。An object of the invention is to prevent cracks in heat exchange pipes.
上記目的を達成するために、本発明は熱交換パイプと伝
熱管を全長にわたってハンダ等で固定し、熱交換パイプ
の肉厚を伝熱管の肉厚より厚くしたものである。In order to achieve the above object, the present invention fixes a heat exchange pipe and a heat exchanger tube over the entire length with solder or the like, and makes the wall thickness of the heat exchange pipe thicker than that of the heat exchanger tube.
熱交換パイプと伝熱管は全長にわたってハンダ等で密着

ものである。Since the heat exchange pipe and the heat transfer tube are closely bonded over the entire length with solder or the like, there is no temperature difference between the two members, and no thermal force is generated due to the temperature difference. Furthermore, even if poor adhesion occurs between the heat exchange pipe and the heat transfer tube, the heat exchange pipe is thicker, so no cracks will occur in the heat exchange pipe.
以下、本発明の一実施例を第1図〜第4図により説明す
る。An embodiment of the present invention will be described below with reference to FIGS. 1 to 4.

プ舎の肉厚を伝熱管6の肉厚よりも厚くしている。As shown in FIG. 8, a combustion storm 2 is located in the upstream part of the combustion gas of the heat exchanger 1, and a burner 3 is located in the OJ flow part. As shown in FIG. 4, the heat exchanger 1rt is made up of a large number of heat-absorbing fins 5 and heat exchange pipes 4 passing through them. As shown in FIGS. 1 and 2, a heat transfer tube 6 is fixed to the upstream portion 8 of the heat exchange pipe 4 with solder or the like 7 over its entire length. . Further, the wall thickness of the heat exchange pipe housing is made thicker than the wall thickness of the heat exchanger tubes 6.

熱交換パイプ4と伝熱管6riハンダ等7により固定さ
れている丸め、熱伝導が良く温度差は発生しない。In such a configuration 2, the combustion gas generated by the burner 8 passes through the combustion chamber 2 and exits through the gaps between the heat exchanger fins 5 of the heat exchanger 1. The water receives heat through the heat absorbing fins 5, the heat exchange pipes 4, and the heat transfer tubes 6, and exits as high-temperature water. In this case, the upstream side 8 of the heat exchange pipe 4 has a higher temperature than the heat exchanger tube 6 because of the high temperature of the combustion gas. however,
The heat exchange pipe 4 and the heat transfer tube 6ri are rounded and fixed by solder etc. 7, so heat conduction is good and no temperature difference occurs.
したがって、熱交換パイプ1と伝熱管6の熱膨張差によ

る。In addition, even if thermal stress occurs due to poor adhesion between the heat exchange pipe 6 and the heat exchange tube 6, the wall thickness of the heat exchange pipe 4 is made thicker than that of the heat exchange tube 0. heat exchange pipe 4
There are no cracks and no water leaks or other accidents.
本発明によれば、熱交換パイプと伝熱管は全長にわ九り
ハンダ等で固定されているため、温度差がなく、熱応力
が発生することはない。According to the present invention, since the heat exchange pipe and the heat transfer tube are fixed together over their entire length with solder or the like, there is no temperature difference and no thermal stress is generated.
また、万一、熱交換パイプと伝熱管の密着不良が発生し
ても、熱交換パイプに亀裂が入ることはない。Furthermore, even if poor adhesion occurs between the heat exchange pipe and the heat transfer tube, the heat exchange pipe will not crack.
