Space heat pipe radiator based on loop heat pipe

Abstract

The invention provides a space heat pipe radiator based on a loop heat pipe, which belongs to the technical field of spacecraft thermal control. A problem that the imaging quality of an optical instrument in a spacecraft is affected due to large vibration of a space radiator based on fluid loop in the prior art is solved. According to the invention, the space heat pipe radiator based on the loop heat pipe mainly comprises a radiant cooling panel, a crisscross heat pipe network and a loop heat pipe, wherein a plurality of longitudinal grooves are stamped in the internal surface of the radiant cooling panel; the crisscross heat pipe network comprises a plurality of longitudinal heat pipes and a plurality of transverse heat pipes; the longitudinal heat pipes correspond to the longitudinal grooves one to one; the longitudinal heat pipes are fixed in the longitudinal grooves and in close contact with the inner walls of the longitudinal grooves; the transverse heat pipes are vertical to the longitudinal heat pipes and fixed on the internal surface of the radiant cooling panel; and a condenser of the loop heat pipe is fixed in an exposed area of the internal surface of the radiant cooling panel. The space heat pipe radiator based on the loop heat pipe, provided by the invention, has the advantages of high heat transmission capacity, high temperature control accuracy, high reliability and small vibration and substantially has no influence on the imaging quality of the optical instrument in the spacecraft.

Description

technical field [0001] The invention belongs to the technical field of aerospace thermal control, and in particular relates to a space heat pipe radiator based on a loop heat pipe. Background technique [0002] In the space environment, the aircraft cannot use conduction and convection to dissipate its waste heat into space, and radiation heat dissipation is almost the only way for space vehicles to dissipate heat. A space radiator is a cooling system on a space vehicle, which radiates waste heat from a heat source to space through its surface. [0003] With the development of manned spaceflight and deep space exploration, the power consumption of space vehicles has also increased rapidly, from several kilowatts to hundreds of megawatts, which has brought great challenges to the heat dissipation performance of radiators; secondly, radiators encounter space The probability of debris and micro-meteoroid impacts is greatly increased, which puts forward higher requirements for ...
