Abstract

The invention provides an on-off controllable heat conducting mechanism, which comprises a graphite heat conducting strip, a movable heat conducting sheet, a fixed heat conducting sheet, a heat insulation pad and a phase change heat storage sheet. One end of the graphite heat conducting strip is fixed to a high-heating device or equipment, and the other end of the graphite heat conducting strip isfixed to the movable heat conducting sheet capable of moving. The fixed heat conducting sheet, the heat insulation pad and the phase change heat storage sheet arranged closely are fixed to another equipment or cabin board. The movable heat conducting sheet can move back and forth among the fixed heat conducting sheet, the heat insulation pad and the phase change heat storage sheet. The on-off controllable heat conducting mechanism of the invention not only can play a temperature equalization role, but also can switch off / on the heat transfer path of controlled equipment by using an executingcomponent and control the temperature level of the controlled equipment under different thermal conditions.

Description

technical field [0001] The invention relates to the technical field of spacecraft thermal control, in particular to a controllable on-off heat conduction mechanism. Background technique [0002] The spacecraft thermal control technology is mainly used to ensure that the structural components and instruments of the spacecraft are in a suitable temperature range in the space environment, so that they can work normally. At present, the thermal control methods widely used in spacecraft can be roughly divided into two categories: passive and active. [0003] When the satellite is in orbit, the temperature of a certain device is too low and needs to be heated. Other times, the device is at a normal temperature and does not require heating. If the device is designed for active heating, the energy requirements of the satellite increase. If other devices with higher temperature can be used for heat transfer, so that the temperature of the device with lower temperature can be raise...
