Plate type heat pipe with separation channels

Abstract

The invention relates to a plate type heat pipe with separation channels. According to the plate type heat pipe, one or more sets of separation channels are arranged in a plate type base body, one set of separation channels is composed of at least one evaporation channel and at least one condensation channel, the evaporation channels and the condensation channels are separated by reinforcing ribs, and capillary narrow clearances are formed in the reinforcing ribs. Working media with the phase-change heat transfer function are poured into the channels, and efficient heat transfer of the heat pipe is achieved. According to the plate type heat pipe, interface friction shear force of a vapor phase and a liquid phase in the work process of the heat pipe can be greatly reduced, and the novel plate type heat pipe has the obvious advantages of being low in heat resistance, high in heat exchange capacity, high in heat exchange efficiency, large in inclination range and the like, and is light, simple in structure, high in loading capacity, simple in manufacturing process, efficient, practical and low in cost.

Description

technical field [0001] The invention relates to the technical field of phase change heat transfer and heat exchange, in particular to a plate heat pipe with separation channels. Background technique [0002] In recent years, plate heat pipes have attracted more and more attention in the fields of microelectronic heat dissipation, solar heat collection, heat recovery, etc. due to their high heat transfer performance, which is convenient for uniform heat transfer in a large area, and researchers have conducted a lot of research . During the working process of the plate heat pipe, the gas-liquid two-phase reversely moves at a high speed in the same tiny channel, which generates a large friction and shear force at the gas-liquid interface, which greatly increases the heat transfer resistance and restricts the heat transfer capacity of the heat pipe. In addition, the manufacturing process of the existing plate heat pipe is relatively complicated, and the manufacturing cost is hi...
