The invention relates to an auxiliary heat transfer mechanism, an outboard load and a space station. The auxiliary heat transfer mechanism is used for conducting heat of an outboard load radiating surface to a space station bulkhead cold plate, and comprises a heat conduction assembly and an electric pushing mechanism. The hot end of the heat conduction assembly is connected with an outboard loadradiating surface. The cold end of the heat conduction assembly is located on the free side of the electric pushing mechanism. Under the pushing of the electric pushing mechanism, the heat conductionassembly moves towards the space station bulkhead cold plate. After the electric pushing mechanism is powered on, the cold end of the heat conduction assembly is pushed to move towards the space station bulkhead cold plate; when the cold end of the heat conduction assembly abuts against the cold plate, the hot end of the heat conduction assembly is connected with the outboard load radiating surface such that the heat of the outboard load radiating surface can be conducted to the cold end of the heat conduction assembly through the hot end of the heat conduction assembly and then conducted to the space station bulkhead cold plate, therefore heat dissipation of the outboard load is achieved, unmanned outboard operation is achieved through the electric pushing mechanism, and heat dissipationof the outboard load is achieved only through electric signals.
本发明涉及一种辅助传热机构、舱外载荷和空间站,用于将舱外载荷散热面的热量传导至空间站舱壁冷板,包括导热组件和电动推动机构,导热组件的热端用于与舱外载荷散热面连接,导热组件的冷端位于电动推动机构的自由侧,且在电动推动机构的推动下朝向空间站舱壁冷板移动,电动推动机构通电后,推动导热组件的冷端朝向空间站舱壁冷板移动,当导热组件的冷端与冷板抵接时,由于导热组件的热端与舱外载荷散热面连接,舱外载荷散热面的热量可通过导热组件的热端传导至导热组件的冷端,再传导至空间站舱壁冷板,实现舱外载荷的散热,通过电动推动机构实现无人舱外操作,仅仅靠电信号实现舱外载荷的散热。
