Abstract

The invention provides a vacuum environment tester which comprises a vacuum sealing chamber, an experimental device, an experimental platform, a heating assembly and a cooling assembly. The vacuum sealing chamber internally includes an experimental space, the experimental device and the experimental platform are arranged in the vacuum sealing chamber, and the heating assembly and the cooling assembly are arranged on the experimental platform. The cooling assembly comprises a liquid nitrogen cold box, a liquid nitrogen input pipe and a nitrogen output pipe, and a liquid nitrogen volatilizationspace is formed in the liquid nitrogen cold box. The liquid nitrogen input pipe and the nitrogen output pipe are connected with the liquid nitrogen cold box, liquid nitrogen is input to the liquid nitrogen volatilization space via the liquid nitrogen input pipe, volatilized nitrogen is led out of the liquid nitrogen volatilization space via the nitrogen output pipe, and the liquid nitrogen cold box is used to cool a test element. Via technical schemes of the invention, extremely severe temperature change conditions of outer space can be simulated more effectively, and the tested element can betested more comprehensively.

Description

technical field [0001] The invention relates to the technical field of experimental equipment, in particular to a vacuum environment testing instrument. Background technique [0002] In the 20th century, mankind has made brilliant achievements in the field of aerospace. In the 21st century, the aerospace industry is booming, and more high-level aerospace activities will be carried out. At present, human beings are developing various space probes to explore other planets in the solar system and even outer space. Aerospace technology is a comprehensive manifestation of a country's comprehensive strength, and its role will go far beyond the field of science and technology itself, and will have a wider and far-reaching impact on politics, economy, military, and even human social life. Aerospace technology is inseparable from the development and breakthrough of aerospace material technology, and one of the key materials is insulating material. [0003] Aerospace equipment works...
