Infrared Space Environment Ground Simulation Device

   The Xuchang Infrared Technology Research Institute Co., Ltd. is located on Yongxing East Road, New Technology Development Zone (Zhongyuan Electrical Valley) in Xuchang, Henan. Its predecessor was the Xuchang Infrared Technology Research Institute, and it is one of the influential infrared heating research institutions in China. The Xuchang Infrared Space Environment Ground Simulation Facility, when conducting thermal simulation tests for spacecraft and extravehicular suits, focuses primarily on the impact of the environment on the thermal properties of the test specimens. Radiative heat transfer has become the dominant mode of heat transfer, with the effects of convection and conductive heat transfer becoming negligible.

    During space vehicle and extravehicular space suit space environment thermal simulation tests, the primary concerns are the effects of the environment on the thermal properties of the test specimens. Radiative heat transfer has become the dominant form of heat transfer, with convective and conductive heat transfer effects negligible. Therefore, infrared space simulation equipment can now realistically simulate the heat exchange effects of the space vehicle's flight trajectory. Only for some special tests, such as dry friction and cold welding tests, do higher test equipment requirements arise. Solar radiation simulation tests can mimic the solar spectrum thermal and photochemical effects on space vehicles and extravehicular space suits. If only the thermal effects are simulated, it is referred to as space external heat flow simulation. There are two methods to simulate space external heat flow: one is the incident flow simulation method...,Also known as the solar simulation method; another type is the heat flux absorption simulation method, also referred to as the infrared simulation method. For specimens with complex shapes and surface materials, the solar simulation method is generally preferred; for specimens with regular shapes and single surface material shapes, the infrared simulation method can be used. To simulate the photochemical effects of ultraviolet radiation environments, an ultraviolet radiation simulator can be utilized. To mimic the space cold black environment, components made of aluminum, copper, or stainless steel are typically used, with their inner surfaces coated in a high-absorption rate special black paint, and liquid is introduced into the interior of the components. This device is called a heat sink. Currently, all space-faring nations around the world use this type of heat sink with liquid as the cooling source to simulate the space cold black environment, as thermal analysis theoretical calculations and experimental data analysis indicate that using77KLiquid temperature and absorption rate0.9The above heat sinks simulate a space cold black environment, with a simulation error of only1%Left and right, it fully meets the requirements for the cold black environment simulation test. Additionally, pursuing lower temperatures is not   Necessary, and it will significantly increase the technical complexity and investment in simulation equipment.
