Système de contrôle de la température de réfrigération et de chauffage pour les essais de dissipateurs thermiques sous vide dans l'aérospatiale

The following are the specific applications and characteristics of refrigeration and heating temperature control system in aerospace vacuum environment heat sink testing:

Wide Temperature Range: The refrigeration and heating temperature control system can provide a wide temperature range from extremely low temperature (such as -180°C) to high temperature (such as 200°C), simulating extreme temperature changes in space environment.

Accurate Temperature Control: The equipment has high-precision temperature control capability, which can accurately adjust the temperature in the test chamber to ensure temperature stability and accuracy during the test.

Vacuum Environment Simulation: The test chamber can operate under vacuum conditions to simulate the low pressure conditions in the space environment to evaluate the thermal performance of aerospace equipment in a vacuum environment.

Heat Sink Test: The cooling and heating temperature control system can simulate the conditions of the heat sink, that is, simulate the process of heat exchange between the spacecraft and the cosmic background radiation in space through thermal radiation, which is used to evaluate the design performance of the spacecraft thermal control system.

Rapid Temperature Change: It can quickly switch between high and low temperatures, simulate the temperature changes of the spacecraft in the earth’s orbit and under the sun, and evaluate the thermal cycle performance of the equipment.

Data Recording and Analysis: It can automatically record the temperature data and other key parameters during the test, which is convenient for subsequent data analysis and evaluation of test results.

Safety and Protection: It has a variety of safety protection measures, such as over-temperature protection, over-current protection, etc., to ensure safety during the test.

Automated Testing: It is usually equipped with an automated control system, such as PLC or a more advanced automated system, to realize the programming, execution and monitoring of the test program, and improve the test efficiency and accuracy.

Scalability and Compatibility: The design takes scalability and compatibility into consideration, and can be integrated with a variety of test equipment, supporting a variety of test standards and protocols.

Durability and Maintenance: Durable materials and design are used, easy to maintain and maintain, ensuring long-term stable operation.
