Abstract

The invention relates to a high-efficiency heat dissipation device used for moving parts of a space camera, and belongs to the technical field of heat dissipation devices. It solves the technical problems of high absorption rate, large heat absorption, and difficulty in heat dissipation in continuous high-frequency motion in the prior art of space camera moving parts. The heat dissipation device of the present invention comprises thermally conductive glue, graphite film, thermally conductive ring, thermally conductive filler, annular support, piezoelectric drive and radiator; It is composed of a fixed seat; the graphite film is fixedly connected to the back of the movable part and the outer wall of the fixed sleeve through thermal conductive glue. The heat dissipation device has strong heat dissipation capacity, fast heat dissipation speed, high heat dissipation efficiency, and improved reliability, and will not affect the high-frequency motion function of the movable parts, so that the movable parts can work stably for a long time continuously and can be used for real-time directional detection.

Description

technical field [0001] The invention belongs to the technical field of heat dissipation devices, and in particular relates to an efficient heat dissipation device for moving parts of a space camera. Background technique [0002] With the gradual exploration and in-depth research of deep space by space cameras, the requirements for large heat dissipation of cameras have also increased accordingly. In particular, some important moving parts in the space camera will be affected by solar radiation, earth infrared radiation and the external heat flow of the earth's reflection. Sometimes the internal heat source will also cause the temperature of the moving parts of the camera to rise rapidly, and the heat dissipation demand will increase. Therefore, it is necessary to use Necessary cooling measures to dissipate heat from the moving parts of the space camera. [0003] Coating high-emissivity coatings on the surface of moving parts and using radiation to dissipate heat to a cool b...
