Abstract

Abstract: Space environment simulation test is mainly used to simulate the cold-black environment, vacuum environment and solar radiation environment in space, which can verify the rationality of thermal and structural design of spacecraft. The effective space of the vacuum thermal environment test system for deep space detector is 3.35 meters in diameter and 5 meters in length. The equipment mainly includes vacuum vessel, heat sink, nitrogen system, vacuum-pumping system, external heat flux system, environmental monitoring system, measurement and control system. The ultimate vacuum of the equipment is 3.2×10^-5 Pa, the average temperature of the heat sink is less than 80K, and the temperature homogeneity of the heat sink is 3.5K. The equipment has been used for several whole-spacecraft tests, the various technical indexes of the whole system are all superior to the design targets.

Key words: vacuum pumping, heat sink, external heat flux, thermal vacuum test, centralized monitoring
