Problems solved by technology

[0003] Because there is no heat convection in the space environment, and thermal radiation requires a large radiation surface, it cannot meet the small-size, high-power heat dissipation requirements of the external load. Usually, the external load (external exposure test load) is placed in the experimental process by heat conduction. The heat generated is transferred to the cold end of the bulkhead

Abstract

The invention relates to an auxiliary heat transfer mechanism, an external load and a space station, which is used for conducting the heat of the heat dissipation surface of the external load to the cold plate of the bulkhead of the space station, including a heat conduction component and an electric driving mechanism, and the hot end of the heat conduction component is used to communicate with the space station The heat dissipation surface of the external load is connected. The cold end of the heat conduction component is located on the free side of the electric propulsion mechanism, and is driven by the electric propulsion mechanism to move towards the cold plate of the bulkhead of the space station. After the electric propulsion mechanism is powered on, the cold end of the heat conduction component is pushed towards the space station. When the cold plate of the bulkhead moves, when the cold end of the heat conduction component touches the cold plate, since the hot end of the heat conduction component is connected to the heat dissipation surface of the external load, the heat of the heat dissipation surface of the external load can be conducted to the heat conduction surface through the hot end of the heat conduction component. The cold end of the component is then transmitted to the cold plate of the bulkhead of the space station to realize the heat dissipation of the external load. The electric propulsion mechanism is used to realize unmanned external operation, and the heat dissipation of the external load is realized only by electrical signals.

Description

technical field [0001] The invention relates to the technical field of structural design of a heat transfer system for an external load of a space station, in particular to an auxiliary heat transfer mechanism, an external load and a space station. Background technique [0002] With the development of manned spaceflight technology, establishing a long-term habitable and working environment in outer space has become the focus of human spaceflight. With the establishment of the manned space laboratory and the planning of the manned space station, there will be a significant increase in space extravehicular exposure experiments. A large number of scientific experiments have been carried out in the space exposure environment abroad, from some simple material exposure experiments on the space laboratory (Skylab) in the United States in the 1970s to the Soviet Union (later Russia) in the Mir Systematic multidisciplinary exposure science experiments have been carried out on the sp...
