The technical solution of this utility model improves the evaporation effect of the evaporator;

[0004] The above application document achieves a uniform evaporation effect by setting the specifications of both ends of the tube body and its specifications. However, in order to ensure the heat conduction effect, a traditional thin copper tube is used as a transmission component. However, firstly, the specifications of the traditional copper tube and the flow rate inside it limit the air cooling effect.

[0005] Therefore, we proposed an air-cooled modular machine with shell and tube evaporator. Utility Model Content

[0009] The branch pipe is a copper pipe, and the radius of the branch pipe is twice the radius of the main copper pipe;

[0010] The sleeve part is composed of an outer sleeve and an inner sleeve which are assembled inside and outside.

[0011] Preferably, the branch pipe part is a thickened copper pipe, and the thickness of the branch pipe part is twice the thickness of the main copper pipe;

[0013] Preferably, an external thread groove is provided in the inner side wall of the outer sleeve, and an internal thread groove matching the specification of the external thread groove is provided on the outer wall of the inner sleeve;

[0014] Among them, the arrangement of the two sets of inner and outer thread grooves makes it easy to fit the sleeve part while increasing the contact area therebetween, thereby ensuring the heat conduction effect and the subsequent air cooling effect.

[0015] Preferably, the thickness of the outer sleeve and the inner sleeve in the sleeve portion is the same as the thickness of the main copper tube;

[0016] The overall thickness of the sleeve is twice that of the main copper tube, which further increases the service life.

[0017] Preferably, the air cooling pipe group is formed by connecting a branch pipe portion bent into a U shape and a corrugated sleeve portion;

[0018] The shape of the air-cooling tube group is arranged to facilitate the flow path of the fluid inside it, thereby ensuring the cooling effect.
