Abstract

The invention relates to a high/low temperature space environment simulating container with a high temperature change rate, comprising a main cabin body, a cabin door, a head sink arranged in the main cabin body, a door sealing structure for connecting the main cabin body and the cabin door, an insulating channel passing through the main cabin body, a sample carrier table, a high/low temperature camera assembly, a high/low temperature fluid stirrer, a temperature measuring system, a pressure measuring system and a vacuumizing structure. A non-high-vacuum environment is formed in the container and is filled with helium; besides radiative heat transfer same as the heat transfer manner of a heat vacuum tank, natural convection heat transfer, even forced convection heat transfer, is added in the cabin, so heat transfer speed is increased greatly, a high/low temperature environment (68K-373K) with a high temperature change rate and even temperature is provided to a sample to be measured. The high/low temperature space environment simulating container is stable, safe and reliable to work.

Description

technical field [0001] The invention relates to a high and low temperature environment simulation system, in particular to a high and low temperature space environment simulation adiabatic container with a non-high vacuum environment in the cabin and features of high temperature change rate and high temperature uniformity. technical background [0002] The space environment simulation system is an important system to test the safety and reliability of aerospace equipment and its components in the space environment or extremely harsh conditions. Taking the moon as an example, because there is almost no atmosphere and atmospheric activities on its surface, the temperature difference between day and night is very large, and the alternation of day and night occurs instantaneously at any position, and the rate of temperature rise and fall is extremely high. Through the space environment simulation system on the ground, before the equipment leaves the earth, it is very necessary t...
