Abstract

The invention discloses a heat sink temperature control system for a thermal vacuum test, comprising a refrigerating system, a secondary refrigerant cooler, a secondary refrigerant heating and temperature controlling system, a circulating pump, a secondary refrigerant buffer container and a heat sink system, wherein the secondary refrigerant heating and temperature controlling system comprises a secondary refrigerant heater for heating a main heat sink, a temperature controller for controlling temperature, a secondary refrigerant heater for heating an auxiliary heat sink and a temperature controller for controlling temperature, so that the temperature of a secondary refrigerant entering a heat sink is controlled by the secondary refrigerant heaters and the temperature controllers. The invention also discloses a temperature control method. Compared with the prior art, the heat sink temperature control system can be used for regulating the temperature of the heat sink in a fixed point, and the temperature of a test piece can be regulated and controlled without infrared electric heating equipment, so that the system is simplified, and the temperature control accuracy is improved.

Description

technical field [0001] The invention belongs to the thermal test technical field in space environment simulation, and in particular relates to a temperature control system and a temperature control method of a heat sink used in a thermal vacuum test. Background technique [0002] Thermal vacuum test is a test unique to spacecraft. It verifies the ability of spacecraft components, subsystems and the entire spacecraft to meet the specified requirements under specified vacuum and thermal cycle conditions, thereby exposing the spacecraft in terms of materials, processes and manufacturing. Potential defects in quality, evaluation of operational performance, tests to verify flight performance. In the thermal vacuum test, it is necessary to control the temperature of the components of the spacecraft within the specified range to verify its working performance. Therefore, in addition to providing a vacuum and cool black environment, thermal vacuum test equipment also requires tempe...
