[0025] like Figure 1-4 As shown, the limiting tube 205 is in contact with the surface of the connector 201 , and the limiting tube 205 and the sleeve 203 are an integrated structure.

[0026] like Figure 1-4 As shown, there are multiple groups of U-shaped tubes 207, and the U-shaped tubes 207 are symmetrically arranged with each other. The U-shaped tubes 207 are welded with the sleeve 203 to form a fixed structure.

[0027] like Figure 1-4 As shown, a limiting groove 209 is provided on the surface of the sleeve 206 , and a spring 210 is provided inside the sleeve 206 . A boss 211 is movably connected inside the sleeve 206 , and a limiting post 212 is fixedly installed on the surface of the boss 211 .

[0029] During implementation, when heat exchange is required, the gas inside the tube body 1 enters the interior of the sleeve 203 and the U-shaped tube 207. At the same time, the surface of the U-shaped tube 207 is provided with heat exchange fins 208, which can further exchange heat for the gas and improve the actual use effect. Due to the setting of the round block 204, the sleeve 203 is divided into two chambers, which is convenient for cooperating with the U-shaped tube 207 for heat exchange.

When gas flows inside the tube body 1, with the cooperation of the spiral tube 304 and the connecting tank 303, heat exchange can be further performed to improve the heat exchange efficiency. At the same time, the threaded cover 306 can be twisted to separate the threaded cover 306 from the connecting tank 303, so that the heat exchange liquid can be injected into the connecting tank 303.
