Abstract

The invention relates to the technical field of heat pipes, in particular to a bisconical microchannel radiator with a thermosyphon loop. The bisconical microchannel radiator comprises a condensationend, an evaporation end and a refrigerant delivery pipe; the refrigerant delivery pipe is used for communicating the condensation end with the evaporation end; the condensation end is provided with acooling water tank; a microchannel condenser is arranged in a cavity of the cooling water tank; a heat-absorbing box is arranged at the evaporation end; the heat-absorbing box is of a cavity structure; a cavity is formed in the cavity structure; the microchannel radiator is arranged in the cavity of the heat-absorbing box; and a refrigerant outlet and a refrigerant inlet which penetrate through the top end of the heat-absorbing box are formed in the microchannel radiator. With negative pressure generated after refrigerant gas is condensed and gravity on condensed refrigerant liquid as circulating power, energy can be saved when the designed radiator obtains high heat exchange performance.

Description

Technical field

[0001] The invention relates to the technical field of heat pipes, in particular to a double-taper microchannel radiator with a thermosiphon circuit. Background technique

[0002] Microfluidic heat dissipation technology is an emerging embedded chip-level enhanced cooling technology. It directly cools the chip through a micro-scale continuous fluid, which minimizes the influence of the thermal resistance between the heat sinks in the remote heat dissipation mode on the heat dissipation efficiency, thereby greatly improving the cooling efficiency of the heat sink. The micro-channel heat sink uses micro-channels to divide the cooling fluid into tiny fluids, and each fluid combination cools the components required to dissipate heat.

[0003] The thermal resistance between the microchannel heat exchanger and the heat exchange environment is extremely low, and it has a very high heat exchange efficiency. The separated fluids exchange heat on different microchannel flow ...
