Moreover, the heat exchange piece 50 is arranged as the spiral heat exchange tube 58, the spiral heat exchange tube 58 has a simple structure, the structure of the spiral heat exchange tube 58 is reasonably utilized, and the spiral heat exchange tube 58 is sleeved outside the tube penetrating channel 37; during processing, the pipe penetrating channel 37 can be arranged in the middle of the water tank 3, so that the spiral heat exchange pipe 58 is also arranged in the middle of the water tank 3, and when water flows in the water tank 3, the water in the water tank 3 can be in contact with the spiral heat exchange pipe 58 through the spiral heat exchange pipe 58, and heat exchange is performed.
The above examples are also not an exhaustive list based on the utility model, and there may be a number of other embodiments not listed. Any substitutions and modifications made without departing from the spirit of the utility model are within the scope of the utility model.
