Abstract

The invention provides a star sensor lightweight thermal control device based on a structure mounting plate. The star sensor lightweight thermal control device based on the structure mounting plate ischaracterized in that the star sensor lightweight thermal control device based on the structure mounting plate comprises a lightweight external-bonded heat pipe, a lightweight pre-embedded heat pipe,a lightweight OSR, a lightweight adhesive, the structure mounting plate and a star sensor bracket. The lightweight pre-embedded heat pipe is pre-embedded in the structure mounting plate, part of thesurface of the lightweight pre-embedded heat pipe is correspondingly mounted with the external-bonded heat pipe, and the other end of the external-bonded heat pipe is mounted on the star sensor bracket. The light OSR is pasted to the surface of the structure mounting plate by using the lightweight adhesive. According to the star sensor lightweight thermal control device based on the structure mounting plate, (1) a star sensor thermal control device of a traditional heating tube of a heat expansion plate is replaced, and the weight of the device is reduced; (2) the heat dissipation efficiency is high, and the star sensor lightweight thermal control device based on the structure mounting plate can meet the strict requirements from the star sensor on temperature; and (3) disassembly and assembly of the star sensor are convenient.

Description

technical field [0001] The invention relates to a heat dissipation device for a satellite star sensor, in particular to the heat control of the star sensor on high-orbit and deep-space exploration satellites with strict requirements on weight resources. Background technique [0002] With the complexity of satellite functions, the integration of stand-alone is getting higher and higher, the star sensor has evolved from the split structure of the head and the line box to the integrated structure of the head and the line box, and the heat consumption has changed from the original 1~ 2W, increased to 12 ~ 20W. And because the star sensor is installed outside the cabin, it is affected by the violently changing external heat flow, and the traditional thermal control method of the heat expansion plate heating tube needs to consume 5-10Kg of weight resources. On the other hand, as the exploration radius increases, the orbital altitude of satellites is getting higher and higher. Fro...
