Loop type heat pipe structure

Abstract

The invention relates to a loop heat pipe structure, comprising evaporator and loop 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 at least two closed ends and two closed ends are fixed in two accommodating holes of evaporator. At the same time, at least one of said two accommodating holes is the penetrating hole through two sides of evaporating body and at least one end of said closed ends extrudes from the accommodating hole, which is via hole, out of the evaporator.

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 evaporator of the known capillary pump suction loop (loop heat pipe), between the evaporator and the pipeline of the loop type heat pipe, the configuration structure of one side inlet and the other side outlet is adopted. When the evaporator and pipeline After being ...

Problems solved by technology

[0003] In the evaporator of the known capillary pump suction loop (loop heat pipe), between the evaporator and the pipeline of the loop type heat pipe, the configuration structure of one side inlet and the other side outlet is adopted. When the evaporator and pipeline After being strung together in a loop, it is difficult to clean, vacuum or degas the inside of the pipeline. The cleanliness and vacuum inside the pipeline cannot be controlled, which will easily affect the heat transfer performance of the finished product.

Simultaneously, the evaporator of this invention application must be combined with two outer sleeves, and after the combination, the two outer sleeves must be sealed by adhesion or welding. The gun must also be carried out around the periphery of the two outer sleeves. At this time, it is easy to be interfered by the surrounding return pipes, which is not convenient for welding or adhesion.

[0004] In addition, when performing brazing (welding), the welding tool (torch) has to rotate 360 ​​degrees around the heat pipe, which will interfere with the heat pipe, and if a disassembled welding torch is used, the assembly and disassembly will take time, which will slow down the production speed. slower

In addition, if soldering is used, the solder will flow into the tube uncontrollably after melting, so that it will be sucked into the capillary tissue and cause blockage in the capillary tissue.
