Micro-channel structure auxiliary driven loop heat pipe

Abstract

The invention relates to heat control equipment, and provides a micro-channel structure auxiliary driven loop heat pipe. The micro-channel structure auxiliary driven loop heat pipe comprises an evaporator and a condenser. A liquid outlet of the condenser communicates with a liquid inlet of the evaporator through a liquid pipeline, a gas outlet of the evaporator communicates with a gas inlet of thecondenser through a gas pipeline, multiple micro-channels are formed in the inner wall of the liquid pipeline and sequentially distributed in the circumferential direction of the liquid pipeline at intervals, and stretch in the length direction of the liquid pipeline, a liquid absorption core is arranged in the evaporator, one end of each micro-channel stretches into the condenser, and the otherend of each micro-channel is connected with the liquid absorption core. The micro-channels are formed in the inner wall of the liquid pipeline, a liquid-state working medium can be conveyed with the help of the capillary effect of the micro-channels, supply of the liquid-state working medium can be continuously provided for the evaporator without gravity assisting and additional power consumption,and the starting reliability and the anti-gravity working stability of the loop heat pipe are guaranteed.

Description

Technical field [0001] The invention relates to thermal control equipment, in particular to a loop heat pipe driven by a micro-channel structure. Background technique [0002] The heat pipe is an efficient heat transfer device, its heat transfer capacity is one or two orders of magnitude higher than the heat conduction of metal, and is called a thermal superconductor. In traditional heat pipes, the capillary structure is usually composed of a channel or a sintered porous structure, and is distributed along the length of the heat pipe. Although the structure is simple, the flexibility is poor. In addition, the capillary structure is covered in the axial direction of the heat pipe, and the liquid flow resistance is large , Liquid and gas flow in opposite directions in the same space, and there is a problem of carrying, which affects the heat transfer capacity of the heat pipe to further improve. [0003] The loop heat pipe is an improved and optimized high-efficiency heat transfer d...
