Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of heat pipes, in particular to a batch detection system for isothermal performance of pre-buried heat pipes, in particular to a batch detection system for isothermal performance of honeycomb plate pre-buried heat pipes for spacecraft. Background Art
[0002] With the rapid development of space science and technology, various stand-alone devices carried in spacecraft are constantly optimized and integrated in limited space. In the complex space environment, the heat emitted by the operation of stand-alone devices and the huge temperature difference caused by the spacecraft facing the sun and facing away from the sun during orbital operation are likely to cause damage to stand-alone devices and other products, thus affecting the performance of the spacecraft.
[0003] Heat pipes can reduce the temperature difference between the various parts of the spacecraft's external structure and achieve partial isothermalization, thereby improving the working temperature conditions of solar cells and increasing output power to achieve temperature uniformity of the instrument cabin structure and internal instruments and improve working temperature conditions. They can also solve the heat dissipation problem of electronic equipment and components carried by spacecraft: the heat can still be distributed to a larger heat dissipation surface (radiation plate) and converted into low heat flux density heat to be dissipated outward. Therefore, the qualification of the heat pipe's isothermal performance is crucial.
[0004] Heat pipes in spacecraft can be divided into external heat pipes and pre-buried heat pipes. External heat pipes are fixed to the surface of the instrument panel by screws, while pre-buried heat pipes are manufactured heat pipes that are buried in the instrument panel during the development of the instrument panel and finally solidified together.
[0005] At present, for honeycomb panels with embedded heat pipes for spacecraft, before conducting isothermal performance tests, the honeycomb panels need to be placed on a leveled marble platform to ensure that the embedded heat pipes are placed horizontally. Because the embedded heat pipes in the honeycomb panels have different specifications and shapes, it is difficult to ensure safety in batch testing. Traditional isothermal performance tests use heating plates to stick on the honeycomb panels. After the test, there will be a lot of residual glue on the honeycomb panels, which is extremely troublesome to clean. Utility Model Content
