Abstract

The invention discloses an active thermal control method for a satellite solar panel, belongs to the technical field of control of satellites with large accessories, and aims to solve the problem thatthe efficiency of the solar panel is reduced due to the fact that the solar panel has no effective active thermal control method and the temperature of the panel is high in the prior art. The methodcomprises the following steps: covering the upper surface of a solar cell with a glass layer, a reflecting film and an antireflection film in sequence; selecting the installation mode of the solar cells and the solar sailboard according to the heat dissipation requirements of the solar sailboard and equipment in the satellite body: when the heat dissipation requirements of the solar sailboard aresmaller than the heat dissipation requirements of the equipment in the satellite body, installing the coated solar cells and the uncoated solar cells on the solar sailboard at intervals; when the heatdissipation requirement of the solar panel is greater than the heat dissipation requirement of equipment in the satellite body, mounting the coated solar cell piece on the solar panel; then installing the solar sailboard and the satellite body in a heat insulation mode, and conducting heat conduction installation at the connecting position of the satellite body heating equipment and the solar sailboard. The method is used for the satellite solar panel.

Description

technical field [0001] The invention relates to an active thermal control method for satellite solar panels, and belongs to the technical field of control of satellites with large accessories. Background technique [0002] With the increase in the integration of satellite functions and the increase in its volume and weight requirements, the requirements for the power generated by solar panels and the requirements for the volume and size of the panels are becoming more and more stringent. It is necessary to maximize the size of the panels within a limited size. Output Power. The output power of solar panels decreases with the increase of temperature, so in order to increase the output power of solar panels, it is necessary to reduce the temperature of the panels as much as possible. At the same time, since the sail board absorbs solar radiation, the temperature is relatively high, and reducing the temperature of the sail board is of great benefit to the internal thermal cont...
