Problems solved by technology

[0003] The steam that the loop heat pipe needs to generate during the start-up process pushes the liquid to flow to the condenser. However, when the heat load is small, the loop heat pipe starts very slowly. In addition, due to the problem of back heat conduction in the flat-plate loop heat pipe, it is difficult to May fail to start under load conditions

Abstract

The invention discloses a loop heat pipe capable of being rapidly started. The loop heat pipe capable of being rapidly started comprises an evaporator, a condenser, a steam pipeline and a liquid pipeline, wherein the evaporator and the condenser are connected through the steam pipeline and the liquid pipeline. A PTFE film is arranged at an inlet, where the steam pipeline enters the condenser, in the tail end of the steam pipeline, and thus, liquid working media are prevented from entering the steam pipeline. According to the loop heat pipe capable of being rapidly started, the start time of the loop heat pipe is shortened, and meanwhile, it is ensured that the loop heat pipe can be smoothly started under a small heat load condition.

Description

technical field [0001] The invention relates to the technical field of loop heat pipe structure, in particular to a loop heat pipe capable of quick start. Background technique [0002] The loop heat pipe is a loop system that relies on capillary suction to drive the circulation of the working fluid and utilizes the phase change of the working fluid to transfer heat. It is a split heat pipe developed from the heat pipe. Compared with the heat pipe, the difference is that the capillary structure only exists in the evaporator, and the evaporator and the condenser are separated, and the steam pipeline and the liquid pipeline can be arranged arbitrarily, so the loop heat pipe has a wider scope of application. In addition, the loop heat pipe has the advantages of strong heat transfer capacity, good isothermal performance, long transmission distance and high safety factor, and is an ideal heat transfer device. [0003] The steam that the loop heat pipe needs to generate during th...
