Description

Technical Field

[0002] Thermal vacuum testing refers to the testing of spacecraft, satellites, carriers and their various components in a vacuum environment and certain temperature conditions to verify various performance and functions. Thermal vacuum testing is a necessary experiment for aerospace engineering products and materials. Thermal vacuum testing can assess the thermal design of aerospace products and materials.

[0003] However, the existing test environment is in a vacuum state, and the thermal conductivity of the gas is very small. Due to the special nature of the thermal vacuum test, the thermal vacuum box cannot be too large in design, so it is not easy to dissipate heat for the products placed in it. When the product is powered on and is in the high-temperature stage, the temperature inside the product rises due to the heat emitted by the product itself and the accumulation of thermal radiation during the high-temperature process. It is impossible to simulate the system-level heat dissipation method of the product in space, which can easily cause the product to burn out during the thermal vacuum test. Utility Model Content

[0004] To this end, the utility model provides a cold plate transfer heat dissipation device for thermal vacuum testing to solve the above-mentioned problems in the prior art.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] Furthermore, universal wheels are arranged around the bottom of the water cooler, and grooves are arranged on both sides of the outer surface of the water cooler.

[0008] Furthermore, an adjustment key is fixedly installed on the left end of the top of the water cooler, and an operation screen is fixedly installed on the right end of the top of the water cooler.

[0009] Furthermore, a door is movably mounted on the front surface of the water cooler, and a handle is fixedly mounted on the left end of the front surface of the door.

[0010] Furthermore, a water inlet is arranged at the left end of the bellows, and a water outlet is arranged at the right end of the bellows.

[0011] The utility model has the following advantages: through the setting of the water cooler, the internal liquid can be refrigerated, through the setting of the delivery pipe, the effect of conveying the water-cooled liquid to the bellows is achieved, through the setting of the bellows and the cold plate, the effect of cooling and cooling the thermal vacuum box and the thermal vacuum tank is achieved, and through the setting of the one-way valve and the mounting flange, the effect of opening and closing the liquid switch is achieved, which solves the problem that due to the heat emitted by the product itself and the accumulation of thermal radiation during high temperature, the temperature inside the product rises, and the system-level heat dissipation method of the product in space cannot be simulated, which easily leads to the problem of product burning in the thermal vacuum test.
