Abstract

The invention discloses an evaporator and a liquid reservoir used for a loop heat pipe and belongs to the technical field of evaporators. A capillary core structure is adopted for spacing inner spaces of the evaporator and the liquid reservoir, liquid in the liquid reservoir can enter the evaporator through the capillary core, meanwhile the liquid is heated and evaporated to generate steam in the evaporator, and the steam flows out of a steam outlet in an end cover of the evaporator. Due to the fact that the capillary core can generate capillary pressure, the steam in the center of the evaporator can be effectively prevented from entering the liquid reservoir, distribution and flowing of the gas liquid are controlled, and then heat leakage from the evaporator to the liquid reservoir is effectively reduced. The distribution and a flowing route of the gas liquid in the evaporator are adjusted initiatively, therefore the radial heat leakage from the evaporator to the liquid reservoir can be completely eliminated, and the purpose that the heat leakage from the evaporator to the liquid reservoir is effectively reduced is achieved so that starting performance and running stability and reliability of the loop heat pipe can be improved.

Description

technical field

[0001] The invention relates to the technical field of evaporators, in particular to an evaporator and a liquid storage device for a loop heat pipe and applications thereof. Background technique

[0002] The loop heat pipe is a high-efficiency two-phase heat transfer device, which uses the evaporation and condensation of the working fluid to transfer heat, and the circulation of the working fluid is driven by the capillary pressure generated by the capillary core of the evaporator without external power. Compared with other heat transfer equipment, the loop heat pipe has outstanding advantages such as large heat transfer, long transfer distance, high temperature control accuracy, strong anti-gravity capability, compact structure, convenient installation, and autonomous operation. And the cooling of electronic components and other fields have broad application prospects.
