Loop type heat pipe structure

Abstract

The invention relates to a loop heat pipe structure, comprising evaporator and closed pipe. The evaporator comprises the evaporator body made of heat conducting material. At least two accommodating holes are set on the evaporator body and at least one channel hole through all accommodating holes are set on it. In addition, the closed pipe comprises a first pipe and at least a second pipe. Ends of the first and the second pipes are heating ends and are fixed in two accommodating holes of evaporator respectively. The other end is connecting end and ends are connected continuously to constitute the cycling loop. At the same time, liquid sealing zone with flat pipe inner diameter is formed between heating and connecting ends in the first pipe.

Description

technical field [0001] The invention relates to a loop heat pipe structure, in particular to a connection structure between an evaporator of a loop heat pipe (Loop Heat Pipe) and its pipe body loop. Background technique [0002] The loop heat pipe (Loop Heat Pipe) is a heat exchange cycle system in which the flow directions of the gas and liquid phase working fluids are all in the same direction. It is similar to the heat exchange principle in the known heat pipe (Heat Pipe), but it does not There will be no problem that the working fluid of the known heat pipe flows into each other when the liquid and gas phases change, so the heat transfer efficiency is superior to that of the known heat pipe. [0003] In the known evaporator of the capillary pump suction loop (loop heat pipe), between the evaporator and the pipeline of the loop type heat pipe, an arrangement structure of one side inlet and the other side outlet is adopted. When the evaporator and the pipeline are connect...

AI Technical Summary

Problems solved by technology

When the evaporator and the pipeline are connected in series, it is difficult to clean, vacuum or degas the inside of the pipeline, and the cleanliness and vacuum degree of the inside cannot be controlled, which will easily affect the heat transfer efficiency of the finished product

At the same time, the evaporator must be combined with two outer casings. After the combination, the two outer casings must be glued or welded tightly. However, the adhesion or welding is the periphery of the two outer casings, so the welding torch or adhesive gun must also be bypassed. The peripheral edge of the two outer sleeves travels, and
