Low-flow-resistance energy storage type efficient radiator

Abstract

The invention discloses a low-flow-resistance energy storage type efficient radiator. The low-flow-resistance energy storage type efficient radiator comprises a working medium pipeline, a phase change heat pipe and a honeycomb plate type radiation base plate embedded with the working medium pipeline, wherein the working medium pipeline comprises a planar contact surface which is in surface contact with a non-phase-change side plane of the phase change heat pipe; the phase change heat pipe is connected with the inner surface of the skin on one side of the honeycomb plate type radiation base plate. With application of the low-flow-resistance energy storage type efficient radiator provided by the invention, on the premise of ensuring isothermy inside the radiator, the length of the working medium pipeline can be shortened, the flow resistance of the working medium in the radiator pipe can be reduced, meanwhile the isothermy inside the radiator can be further improved by virtue of the energy storage advantage of the phase change heat pipe, the development demands on the radiator technology can be met, the technology implementation difficulty is low, and the engineering application value can be achieved.

Description

technical field [0001] The invention belongs to the field of thermal control of spacecraft and relates to a radiator, in particular to a low flow resistance energy storage type high-efficiency radiator. Background technique [0002] With the development of aerospace technology, there are more and more high-orbit and inclined-orbit satellites. The cooling surfaces of satellites operating in high or inclined orbits are often illuminated in turn. In order to save precious energy on the planet and improve the heat dissipation efficiency of the heat dissipation surface, the heat dissipation surface that is illuminated in turn is often subjected to isothermal treatment. Nowadays, the usual method is to heat-dissipate the heat dissipation surface by attaching heat pipes, but the heat pipes attached outside cannot satisfy the long-distance transmission of large heat. With the development of spacecraft towards high-power and high-load heat flux, the isothermal treatment method of e...

Problems solved by technology

For existing radiators, especially large radiators, when the working medium pipeline is relatively long, the flow resistance of the internal pipeline of the system will be too large

If the external drive is an LHP system, too much flow resistance may cause the failure of LHP operation; if it is a fluid circuit system driven by a mechanical pump, too much flow resistance of the radiator will increase the power consumption of the mechanical pump; and in order to solve the above problems, the When the design of the working fluid pipeline is relatively short to reduce the internal flow resistance, it will lead to poor isothermal performance of the radiator and reduce the heat dissipation efficiency of the radiator
