The invention belongs to the technical field of spaceflight, and provides a satellite-borne temperature control and installation integrated plate based on a thermoelectric effect. Comprising a high-thermal-conductivity graphite film, an inner aluminum skin, an aluminum honeycomb core, an outer aluminum skin and a thermal control layer which are arranged in sequence and are combined into a composite board in a gluing mode, the periphery of the composite board is sealed through an aluminum adhesive tape to form an integrated board, and a solid-state thermoelectric device is embedded in the aluminum honeycomb core. During use, after one side, corresponding to the high-thermal-conductivity graphite film, of the integrated plate is connected with a to-be-mounted device, the pair of electrodes correspondingly penetrate through the inner aluminum skin and mounting holes reserved in the high-thermal-conductivity graphite film to be connected with a power supply cable, and the direction of current introduced into the solid-state thermoelectric device is changed; therefore, the solid-state thermoelectric device is switched between a refrigeration mode and a heating mode to work, and the normal working temperature of the installed device is maintained. Therefore, the integrated plate is simpler in structure, is not influenced by the gravitation environment during working, does not need to consider the air tightness of the product, is long in service life, and is maintenance-free for life.
本发明属于航天的技术领域,提供了一种基于热电效应的星载控温安装一体化板。包括依次布置的高导热石墨膜、内铝蒙皮、铝蜂窝芯、外铝蒙皮和热控层,并采用胶粘方式结合成为合成板,且合成板的四周通过铝胶带密封封边形成一体化板,铝蜂窝芯内嵌装有固态热电器件。使用时,上述一体化板对应高导热石墨膜的一侧与待安装器件连接完成后,一对电极对应穿过内铝蒙皮和高导热石墨膜上预留的安装孔与电源供电线缆相连,改变通入固态热电器件的电流方向,使得固态热电器件在制冷模式和加热模式之间切换工作,维持安装器件的正常工作温度。因此本发明的一体化板结构更加简单,且工作是不受引力环境影响、无需考虑产品气密性,使用寿命长,终身免维护。
