Infrared heating cage hanging device

Abstract

The invention provides an infrared heating cage hanging device which comprises four in-tank stand columns, a plurality of sleeve supporting frames and a plurality of infrared heating cage clamps. The four in-tank stand columns are all fixed to a platform at the bottom of a space environment simulation room through bolts to form a framework structure, the sleeve support frames comprise sleeves and supporting frames, the sleeves and the supporting frames are connected mutually, the sleeves are connected with the in-tank stand columns in a sleeved mode, and the infrared heating cage clamps are connected with the supporting frames. The infrared heating cage hanging device has the advantages of being simple in structure, high in universality, flexible in mounting and adjustment and convenient to apply, lowering the cost of aircraft product vacuum hot tests, and being beneficial for environmental protection.

Description

technical field [0001] The invention relates to the field of vacuum heat test, in particular to an infrared heating cage suspension device for vacuum heat test. Background technique [0002] In the vacuum heat test of spacecraft products, in addition to simulating vacuum and cold black background, it is also necessary to simulate solar radiation, earth reflection and earth infrared radiation heat flow. The accuracy of external heat flow simulation will directly affect the temperature level and test error of spacecraft product vacuum thermal test. [0003] At present, the infrared heating cage, as a means of simulating heat flow outside space, is widely used in the vacuum thermal test of domestic spacecraft products. It has the characteristics of non-contact and good uniformity of heat flow density. The layout of the infrared heating cage for vacuum heat test is designed according to the test requirements. The test requirements include the requirements of the heat flux reach...

AI Technical Summary

Problems solved by technology

The layout of the infrared heating cage for vacuum heat test is designed according to the test requirements. The test requirements include the requirements of the heat flux reaching the product surface, the distance between the product surface and the uniformity of heat flow, etc. The existing infrared heating cages are all Designed, produced, installed and used according to the specific needs of a certain spacecraft product, the installation and use conditions are complex and diverse, there are many auxiliary tools, and the one-to-one design makes the existing infrared heating cages less versatile
