複数本のヒートバイブが配置されているものである。In the heat exchanger according to the present invention, a high-temperature gas flow path and a low-temperature gas flow path are formed in the casing by a partition wall, and both ends of the high-temperature gas flow path are opened to form a high-temperature gas inlet and a high-temperature gas outlet. The end of the high-temperature gas outlet side is opened to serve as a low-temperature gas inlet, and the end of the high-temperature gas inlet side is closed, and the high-temperature gas inlet side of the high-temperature gas flow path is closed. A plurality of iron pipes are arranged in the section, with one end penetrating the partition wall and opening into the low temperature gas flow path, and the other end opening outside the casing. A plurality of heat vibrators are arranged to penetrate the wall and straddle both flow paths.

The hot gas enters the casing from the inlet, passes through the hot gas flow path, and exits from the hot gas outlet. On the other hand, the supply air enters the casing from the low-temperature gas inlet, passes through the low-temperature gas flow path, passes through the iron pipe, and exits the casing. The heat of the exhaust gas that enters the casing from the high-temperature gas inlet [1] is first transferred to the supply air passing through the iron pipe. Then, the 1) 1 air, which has been deprived of heat from the supply air in the iron pipe and has a reduced level of variola, further travels through the high-temperature gas flow path and reaches the location where the pipes are located. The working fluid in the part of the heat vibrator located in the high-temperature gas flow path is heated and vaporized, and this gaseous working fluid moves to the part of the heat pipe located in the low-temperature flow path. .Here's the supply.
It cools down and condenses. The heat released during condensation is transferred to the supply air, heating it.
こうして、排気からＩＪＩ熱が回収される。In this way, IJI heat is recovered from the exhaust gas.

でき安全性が高い。According to the heat exchanger of the present invention, the heat of the supply air that has entered the high-temperature gas flow path is first taken away by the supply air that passes through the iron vibrator, so that the heat does not reach the location where the heat vibrator is located. By this time, the exhaust temperature has dropped. Therefore, there is no need to use highly toxic sulfur, mercury, sodium, etc. as the working fluid of the heat vibrator, and water, Freon, etc. can be used, resulting in high safety.
