Radiator suitable for space optical remote sensor in sun-synchronous orbit

Abstract

The invention relates to a radiator suitable for a space optical remote sensor in a sun-synchronous orbit and aims to solve the problem that the radiator cannot be arranged on a non-irradiation surface of the remote sensor during actual work. The working efficiency of the radiator can be improved through effectively shielding external heat flow of the sun-synchronous orbit. The radiator is composed of a radiant panel, an earth screen, a solar screen and a side screen, wherein the solar screen shields the solar radiation heat flow and shields the earth infrared heat flow on the side concurrently; the earth screen shields the earth infrared and solar reflection heat flow; and the triangular side screen is used for shielding the earth heat flow from the direction. During actual application, the shielding screens are arranged according to specific gestures and illuminated angle of the remote sensor, the whole or most part of the external heat flow from the sun and the earth directions can be shielded, the structure comprises no driving parts, and the radiator is simple and reliable.

Description

technical field [0001] The invention relates to the technical field of space heat dissipation instruments, in particular to a radiation radiator suitable for space optical remote sensors in sun-synchronous orbits. Background technique [0002] With the development of space-to-Earth observation technology, the imaging electronics system on the space optical remote sensor is becoming more and more complex, and the corresponding work heat consumption is also getting higher and higher, which requires the heat dissipation design to have a higher heat dissipation efficiency. For space optical remote sensors working in outer space, the heat sink is often space cool and black. Therefore, the space radiation radiator is often used as the final way of heat dissipation design, and its heat dissipation efficiency is one of the important factors that determine the heat dissipation design. [0003] At present, the main structure of the radiation radiator is the exposed radiation cooling p...
