Space environment simulation system

Thermal oil temperature adjustment platform environment simulation equipment

The temperature guarantee system of the ring mold equipment of the heat transfer oil temperature adjusting table is mainly composed of the temperature adjusting table, the heat sink and the cold plate. The heat transfer oil unit is used to cool the heat sink. By adjusting the heating power of the heater of the heat transfer oil unit and controlling the operation of the compressor, the heat sink and the cold plate can be adjusted and controlled at - 85 ℃ ~ + 150 ℃. The design of heat sink and cold plate realizes the coexistence of radiation and heat conduction in the vacuum environment, and effectively improves the temperature rising and falling rate of the specimen. This refrigeration method is suitable for small and medium-sized ring mold equipment with narrow temperature range and high frequency.

Composite refrigerant cryogenic unit environment simulation equipment

The temperature guarantee system of the ring mold equipment of the cryogenic unit with compound working fluid is mainly composed of cryogenic unit, heat sink and heating cage. The cryogenic unit cools the heat sink in the vacuum chamber to obtain the low temperature background. By adjusting the output power of the heating power supply of the heating cage, the temperature range of - 140 ℃ ~ + 150 ℃ can be obtained in the vacuum chamber. This refrigeration method is suitable for small and medium-sized ring mold equipment with moderate temperature range.

Driving mechanism life test environment simulation equipment

The driving mechanism life test environment simulation equipment mainly provides a simulated on orbit space environment (temperature gradient, vacuum degree), so that the mechanism can work according to the actual working conditions in this environment. It is mainly used for the thermal vacuum test and accelerated life test of the two-dimensional pointing mechanism to the sun orientation device, so as to fully verify the reliability of the driving mechanism. The equipment adopts composite working fluid and heat transfer oil dual refrigeration technology, which can realize independent temperature regulation of heat sink and cold plate, and is conducive to improving the temperature rise and fall rate and temperature control accuracy of large heat capacity test products.

High-energy detector beam calibration environment simulation device

The beam calibration loop model device of high energy detector provides the simulated thermal vacuum environment for the beam target station of the experimental station on the ground, which is the main equipment of the electron beam line device experimental station of accelerator. The device is the first accelerator beam line device in China that can provide pulse mode quasi single electron beam. It can provide electromagnetic shielding environment, high and low temperature cold black background, clean and pollution-free high vacuum environment for sample beam test, and can be used for electronic calibration test of various space particle detectors.

Multi-purpose vacuum test system

The all-in-one machine type ring mold equipment is developed and designed according to the product of ACS, a foreign advanced thermal vacuum equipment manufacturer. The equipment integrates the vacuum chamber, vacuum unit, temperature adjusting table and control system into a structural module. It has the characteristics of compact structure, small space occupation, convenient transportation and beautiful appearance.
