Confined space phase transition heat dissipation device and confined space phase transition heat dissipation method

Abstract

The invention relates to a confined space phase transition heat dissipation device and a confined space phase transition heat dissipation method, and belongs to the field of confined space heat dissipation to solve the low heat dissipation efficiency and the poor performance of a confined space. The confined space phase transition heat dissipation device comprises: an upper case, a lower case, anda partition, wherein the upper case and the partition constitute an upper heat dissipation cabin; the lower case and the partition constitute a lower heat dissipation cabin; a first heat pipe radiator is arranged in the upper heat dissipation cabin; a second heat pipe radiator is arranged in the lower heat dissipation cabin; the upper portions of the first and second heat pipe radiators communicate with each other through a first refrigerant pipe; the lower portions of the first and second heat pipe radiators communicate with each other through a second refrigerant pipe; a refrigerant is disposed in the heat pipe radiators, and is heated to vaporize and come up to the first heat pipe radiator; after dissipating the heat to the external environment, the refrigerant is liquefied and flows back to the second heat pipe radiator to achieve cyclic heat dissipation; and draught fans are arranged in both the upper and lower heat dissipation cabins to accelerate the air flow. The confined space phase transition heat dissipation device realizes the high-efficiency heat dissipation and the waterproof, dustproof, and electromagnetic shielding functions in a highly confined space.

Description

technical field [0001] The invention relates to the technical field of space heat dissipation, in particular to a phase change heat dissipation device for a closed space and a phase change heat dissipation method for a closed space. Background technique [0002] At present, the heat dissipation methods for macro-heating equipment such as chassis and cabinets in confined spaces mainly include: active ventilation and heat dissipation and passive heat dissipation with heat sinks arranged. [0003] The heat dissipation method of active ventilation introduces fresh air outside the space to be cooled, and through convective heat exchange, the heat generated by the heating equipment is taken out of the space through the air. This method has high heat dissipation efficiency and reliability. There are important applications in the field of heat dissipation, but this method is not suitable for heat dissipation in subordinate confined spaces: 1) Confined spaces with high requirements f...
