There is a gap between the sleeve bodies 3 and the gas pipes 2. The multiple sleeve bodies 3 and the gas pipes 2 form sealed heat exchange channels 4, and the multiple heat exchange channels 4 are interconnected. The sleeve assembly is provided with a water inlet end and a water outlet end. The water inlet end is located below the water outlet end. With the water inlet end located at the bottom, the heat exchange liquid is transported from bottom to top, which can remove most of the air in the heat exchange channels 4 and improve the heat exchange efficiency.

The air pipe 2 has multiple straight pipes, which are evenly distributed in the multiple mounting areas. Adjacent straight pipes are connected by bends. The middle part of the straight pipe is placed in the mounting area, and both ends of the straight pipe extend out of the mounting area. The straight pipe and the bends are fixedly connected by welding. The multiple sleeve bodies 3 are respectively sleeved on the corresponding straight pipes.

[0024] Please see Figure 5 Specifically, in one optional embodiment of this application, sealing rings 5 ​​for sealing are provided inside both ends of the sleeve body 3. The sealing rings 5 ​​are interference-fitted with the straight pipe to achieve sealing of the heat exchange channel 4.
