Description
Technical Field
The utility model belongs to the technical field of warm logical equipment technique and specifically relates to a heat transfer box.
Background
The existing refrigerator uses copper pipe to wind the evaporator matching with the inner container of the low temperature refrigerator, and fixes the evaporator on the outer surface of the inner container of the refrigerator. The liquid refrigerant absorbs the heat in the box body and evaporates into gas through heat conduction in the copper pipe, thereby achieving the purpose of reducing the temperature in the box body.
The existing evaporators have the following disadvantages: (1) due to the reasons that the copper pipe is soft, the evaporator is large in size, the copper pipe needs to be carried for multiple times before the inner container is assembled and the like, the copper pipe is easy to deform during processing, and the scrapping cost is high; (2) because the contact place of the cylindrical copper pipe and the liner is only a tangent line, the contact area is small, and the heat exchange efficiency is seriously influenced; (3) in order to improve the heat exchange efficiency, heat-conducting glue has to be smeared between the copper pipe and the surface of the box body, and the process is complicated and difficult to control.
Therefore, the prior art is in need of improvement.
