Description

Technical Field

[0001] The utility model relates to the technical field of heat pipes, in particular to a thin loop heat pipe. Background Art

[0002] Generally, a heat pipe is composed of a tube shell, a liquid wick and an end cap. The inside of the heat pipe is pumped into a negative pressure state and filled with a suitable liquid. This liquid has a low boiling point and is easy to volatilize. The tube wall has a liquid wick, which is made of capillary porous material. One end of the heat pipe is the evaporation end, and the other end is the condensation end. When one end of the heat pipe is heated, the liquid in the capillary tube vaporizes rapidly, and the vapor flows to the other end under the power of heat diffusion, and condenses at the cold end to release heat. The liquid then flows back to the evaporation end along the porous material by capillary action, and the cycle continues until the temperatures at both ends of the heat pipe are equal (at this time, the thermal diffusion of the steam stops). This cycle is carried out quickly, and heat can be conducted continuously.

[0003] In the prior art, application number 202122769809.9 is a component for reducing the heat transfer temperature difference of a loop heat pipe and a loop heat pipe including the component. The component includes an evaporator and a compensator. The evaporator includes a shell and a capillary structure. By adding a second steam chamber and an auxiliary pipeline, the heat leakage from the evaporator to the compensator causes part of the working fluid to vaporize in the second steam chamber. The vaporized working fluid enters the auxiliary pipeline and finally returns to the compensator through the liquid pipeline to complete the cycle. The vaporization absorbs most of the heat leakage, which can significantly reduce the heat leaking into the compensator and reduce the heat transfer temperature difference of the loop heat pipe. However, it is not convenient to adjust the distance between the evaporator and the condenser, which makes it difficult to meet the use of loop heat pipes of different sizes and volumes, affecting the flexibility of the use of the loop heat pipe.
