Heat performance test device and method for heat pipe under vacuum

Abstract

The invention provides a heat performance test device and a heat performance test method for a heat pipe under vacuum. The device comprises a vacuum tank, a cold plate, a vacuum air extracting system, a refrigeration system and a heating system, wherein the vacuum tank is connected with the vacuum air extract system, the refrigeration system and the heating system respectively through flange connection openings in the surface of the vacuum tank; the cold plate is arranged in the vacuum tank; the vacuum air extracting system is used for extracting air from the vacuum tank, so that the vacuum tank reaches a vacuum degree required by a space environment experiment; the refrigeration system provides refrigeration liquid for the cold plate, thus realizing temperature control on the cold plate and ensuring that the surface temperature of the cold plate is uniform; a heating sheet of the heating system is arranged in the vacuum tank. According to the heat performance test device, a novel refrigeration mode replaces a conventional cooling water cooling mode, so that the test temperature region for the heat pipe is greatly expanded, the requirement of the heat performance test of the heat pipe for the temperature of the space environment is met, the heat performance test temperature range of the heat pipe is expanded, and the heat performance test precision of the heat pipe is improved.

Description

technical field [0001] The invention relates to a thermal performance testing device, in particular to a thermal performance testing device and method for a heat pipe under vacuum, in particular to a testing device and a method for testing the thermal performance of a spacecraft heat pipe in a simulated space vacuum environment. Background technique [0002] Due to the significant difference between the ground environment and space temperature, humidity and other conditions, the performance of the heat pipe will have a certain deviation under different conditions of use. The heat pipe performance test mainly includes the heat transfer performance test and the life test of the heat pipe. The heat pipes used in the spacecraft also need to be tested in a vacuum and low temperature environment to be close to the actual space environment, test the performance of the heat pipes, and ensure the safety of the heat pipes. At present, the temperature range of conventional heat pipe t...
