Test performing device for deep low-temperature substance

Abstract

The invention discloses a test performing device for a deep low-temperature substance, comprising a closed type A main box body and at least one assistant box body, wherein the assistant box body is connected with the A main box body; a deep low-temperature cold box is arranged at one side in the A main box body, the deep low-temperature cold box is provided with an airtight door at the position facing to the A main box body, the inner wall of the deep low-temperature cold box is provided with a cold box body shield, and the inner side of the airtight door is provided with a cold door shield; a solar battery array and a simulating wall are arranged in the deep low-temperature cold box together through a support frame carriage in a furling way, the solar battery array is suspended on two long sliding rails which are suspended on a suspension system positioned on the top of the A main box body, one end of each long sliding rail is arranged in the deep low-temperature cold box, and the other end of each long sliding rail is suspended in the A main box body. The deep low-temperature cold box is arranged in the A main box body with the temperature from -90 DEG C to -100 DEG C, thereby reducing the temperature difference of the A main box body and the external world; in addition, the heat sink type cold box body shield and the cold door shield are adopted, thereby achieving obvious energy-saving effect, saving the test time and obtaining outstanding social and economic benefits.

Description

technical field [0001] The invention relates to a deep-low temperature object deployment test device, which is used for the simulation deployment test of a solar cell array of a space vehicle. Background technique [0002] With the rapid development of space technology, as the main component of aerospace vehicles—the solar cell array is responsible for the important task of providing energy for the aircraft. During the orbital operation in the vacuum environment outside the atmosphere, the aircraft will alternately pass through the high-temperature areas exposed to direct sunlight and The low-temperature area of ​​the shadow, so the solar cell array actually works in an environment of alternating high and low temperature cycles. In order to make it unfold smoothly in the orbit and provide energy for the aircraft, performance tests on the ground that simulate high and low temperature environmental conditions are to ensure its performance. Reliable guarantee of normal work in ...

Problems solved by technology

[0003] However, with the rapid development of aerospace science and technology, in order to meet the needs of space vehicles flying to distant planets for scientific exploration, the low-temperature performance of solar cell arrays in this field requires that the low-temperature performance of solar cell arrays should be in the environment of -185 ° C ~ -195 ° C, and after 24 hours The requirement for smooth deployment after constant temperature, and the minimum allowable temperature of "high and low temperature simulation method and object deployment test device" is -110°C, which cannot meet the conditions for ××-1 solar cell array deep and low temperature deployment test
