Abstract

The invention relates to an integrated liquid cooling machine box based on two-phase heat transfer and a two-phase heat transfer method thereof. The integrated liquid cooling machine box comprises a machine box shell, a two-phase liquid cooling source and a plug-in cold guide plate, wherein flow channels which are communicated with each other are arranged in the top wall and the bottom wall of themachine box shell; the upper end and the lower end of the plug-in cold guide plate are fixedly connected with the top wall and the bottom wall of the machine box shell respectively, and are used forfixing electronic plug-in components; the two-phase liquid cooling source is fixedly connected with the machine box shell; and each flow channel has a flow channel inlet and a flow channel outlet which are communicated with the two-phase liquid cooling source through pipelines. The two-phase liquid cooling source is fixedly connected with the machine box shell and does not need to depend on an external liquid cooling source. The two-phase liquid cooling source is adopted, and a working medium is subjected to liquid state and gaseous state conversion in a pipeline system; the cooling working medium absorbs the heat of electronic equipment in the flow channels and is changed from the liquid state into the gaseous state, so that heat exchange efficiency is far higher than that of single-phasefluid heat exchange; and the cooling working medium phase change is performed in an isothermal process, so that the isothermal performance of the top wall and the bottom wall of the machine box shellis superior to that of the single-phase fluid heat exchange.

Description

technical field [0001] The invention relates to a liquid-cooled cabinet, in particular to an integrated liquid-cooled cabinet based on two-phase heat transfer and a two-phase heat transfer method thereof. Background technique [0002] The existing liquid-cooled chassis includes: a chassis shell, a liquid-cooled cold plate and an electronic plug-in. The electronic plug-in is installed in the chassis shell, and the liquid-cooled cold plate is arranged in the chassis shell and contacts the electronic plug-in. When the chassis is working, the external liquid cooling source provides the cooling medium, and the cooling medium flows through the liquid-cooled cold plate of the chassis to take away heat to ensure the normal operation of the electronic equipment inside the chassis. Existing liquid-cooled chassis completely rely on external liquid cooling sources, and cannot be used in unmanned aerial vehicles and other occasions that do not have liquid cooling sources. The cooling me...
