As a result, the low-temperature side heat exchanger tube 2 locally becomes high in temperature, causing thermal decomposition of the refrigerant. On the other hand, if the low-temperature side heat exchanger tube 2 is damaged, there is a risk that the refrigerant gas will leak out and come into contact with the high-temperature side heat exchanger tube 1, resulting in thermal decomposition of the refrigerant and the generation of toxic gas.

、連続気孔を有する多孔質金属。３で接合されている。In Fig. 1, reference numeral 1 denotes a high-temperature side heat exchanger tube 1 through which high-temperature gas such as combustion gas flows, and a low-temperature side heat exchanger tube 2 having a predetermined distance on the outer periphery of this high-temperature side heat exchanger tube 1 and through which a refrigerant flows. The low-temperature side heat exchanger tube 2 and the high-temperature side heat exchanger tube 1 are made of porous metal having continuous pores. It is joined by 3.
上記構成において、高温側伝熱管１内を流れる燃焼ガス
の熱は、多孔質金属３を伝わシ低温側伝熱管２を通して
、内部を流れる冷媒を加熱する。In the above configuration, the heat of the combustion gas flowing inside the high temperature side heat exchanger tube 1 is transmitted through the porous metal 3 and passes through the low temperature side heat exchanger tube 2, and heats the refrigerant flowing inside.
この時、高温側伝熱管１が破損した場合、内部の高温の

続気孔を通って熱交換器外部へと排出される。At this time, if the high temperature side heat exchanger tube 1 is damaged, the high temperature combustion gas inside will be discharged to the outside of the high temperature side heat exchanger tube 1, but since the pores of the porous metal 3 are continuous, they will pass through the pores. The heat exchanger is then cooled and discharged to the outside of the heat exchanger. On the other hand, even if the low-temperature side heat exchanger tube 2 is damaged and the internal refrigerant is discharged to the outside of the low-temperature side heat exchanger tube 2, this refrigerant passes through the continuous pores of the porous metal 3 and is discharged to the outside of the heat exchanger. be done.

ある。In addition, at this time, the surface of the high-temperature side heat exchanger tube 1 can be kept in a state where it does not reach the temperature at which the refrigerant decomposes due to the fin effect of the porous metal 3, which prevents abnormal conditions such as damage to the heat exchanger tube. Also, there is an effect that decomposition of the refrigerant can be prevented.

In FIG. 3, a plurality of high-temperature side heat exchanger tubes 1 and a plurality of low-temperature side heat exchanger tubes 3 are arranged in parallel, which is different from the previous embodiment. By blowing air, it can also be used as a heat exchanger between air and refrigerant.

器としても使用可能になる。That is, during heating, heat exchange occurs between the high-temperature combustion gas inside the high-temperature side heat exchanger tube 1 and the refrigerant inside the low-temperature side heat exchanger tube 2, while during cooling, the combustion gas is exchanged with the high-temperature side heat exchanger tube 1. By using the refrigerant inside the low-temperature side heat transfer tube 2 as a high heat source and the air outside the heat exchanger as a low heat source, heat exchange between the refrigerant and the air is performed without passing through the heat exchanger, so it can be used as a heat exchanger for both air conditioning and heating. will also be available.
