Problems solved by technology
Therefore, when designing the heat dissipation surface area, the maximum heat dissipation demand under high temperature conditions must be included; and under low temperature conditions, the excess heat dissipation capacity of the heat dissipation surface can only be compensated by on-board heating, which is a waste of on-board energy.
[0004] Some existing space heat radiators mainly use the active pump to drive the heat transfer mode of the loop heat pipe, so as to transfer the heat in the star to the extended heat dissipation surface, and the heat dissipation angle of the extended heat dissipation surface cannot be intelligently adjusted, so that the heat dissipation in low temperature conditions Sometimes it will face the problem of freezing and thawing of the working medium at the cold end, the overall structure is also more complicated, and the reliability is low, so it is not suitable for small-sized satellites

Embodiment Construction
[0021] The technical solutions of the present application will be clearly and completely described below in conjunction with the accompanying drawings and the embodiments of the present application.
[0022] In order to increase the heat dissipation capacity of the satellite, this application uses hinges to install and fix the extended heat dissipation surface, and the heat consumption in the satellite is transferred to the extended heat dissipation surface through flexible heat pipes. The two-way shape memory alloy is used to automatically sense temperature changes, and intelligently adjust the opening and closing angle of the extended heat dissipation surface, so as to meet the heat dissipation requirements of satellites under different working conditions.
[0023] like figure 1 As shown, the intelligent adjustment heat radiator of the present application at least includes: heat pipe evaporation section (1), heat pipe flexible section (2), heat pipe condensation section (3),...

Description
technical field [0001] The present application relates to a heat radiator in the aerospace application field, in particular to an intelligently adjustable heat radiator. Background technique [0002] When the satellite is in orbit, it is necessary to dissipate the heat generated in the satellite to the space, so as to control the temperature of the satellite within the allowable range and ensure the normal operation of the single unit in the satellite. When the satellite is in orbit, the change of external heat flow and internal heat consumption exists under high temperature and low temperature conditions. Under each working condition, satellites have different requirements for cooling capacity. At the same time, the power consumption density level of the payload devices on the satellite is also getting higher and higher. To seek greater cooling capacity based on the limited satellite surface area, it is necessary to expand the cooling area by expanding the radiator. [0...
