[0018] In order to make the purpose, technical scheme and advantages of the utility model clearer, the utility model is described below by the specific embodiments shown in the accompanying drawings. However, it should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. The structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions that can be implemented in the utility model, so they have no technical substantive significance. Any structural modification, change in proportional relationship or adjustment of size, without affecting the effects that can be produced by the utility model and the purposes that can be achieved, should still fall within the scope of the technical content disclosed by the utility model. In addition, in the following description, the description of known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0019] It should also be noted that, in order to avoid obscuring the present invention due to unnecessary details, only structures and / or processing steps closely related to the scheme according to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

The left and right ends of the box body are respectively installed with end plate 1 and end plate 2, and two longitudinal groups of long U-shaped tubes 9 are arranged inside the box body. The two groups of long U-shaped tubes 9 are staggered, and the other ends of the two groups of U-shaped tubes 9 are connected to form a circulation tube through the semicircular tube 4. A connecting pipe 1 5 is installed at one end of the circulation pipe, a needle valve 7 is installed at the end of the connecting pipe 1 5, a connecting pipe 2 6 is installed at the other end of the circulation pipe, a cap 8 is installed at the end of the connecting pipe 2 6, and the cap 8 can achieve the sealing of the connecting pipe 2 6; the long U-shaped tube 9 is a long U-tube expansion tube with a diameter of 7mm, the spacing between the fins 3 is 1.6mm, the needle valve 7 is an expanded needle valve with a valve core, and the end plates 1 1 and 2 have the same structure, both of which are formed by bending the two ends of a plate body outward at a right angle.
