An adaptive phase change cold plate

Abstract

The invention relates to an adaptive phase change cold plate, which comprises a cold plate main body, an air outlet pipe and a liquid inlet pipe are arranged on the top of the cold plate main body, and a heat exchange cavity is arranged inside the cold plate main body. The heat exchange cavity is provided with multiple sets of inclined heat exchange ribs, multiple gas collection grooves located at the edge of the heat exchange cavity, and multiple sets of horizontal grooves near the ends of the heat exchange ribs; The liquid inlet pipe communicates with the bottom corner of the heat exchange chamber through the liquid inlet channel, and the heat exchange ribs are all set towards the connection between the liquid inlet channel and the heat exchange chamber. This solution solves the problem that the existing technology can only be placed vertically Defects, not only can be placed vertically, but also can be placed obliquely. At the same time, it can further reduce the difficulty of air bubbles escaping, facilitate the accumulation of air bubbles in the uppermost gas collection tank, reduce the probability of air bubbles covering the heat exchange surface and affect heat dissipation, significantly Improved heat transfer capacity.

Description

technical field [0001] The invention relates to the technical field of phase change radiators, in particular to an adaptive phase change cold plate. Background technique [0002] The existing phase-change liquid-cooled radiator has a single internal flow channel structure, usually using parallel straight channels. After the refrigerant in the flow channel absorbs heat and gasifies, the saturated gas floats up along the flow channel, accumulates in the top air cavity, and passes through the outer pipeline. After circulation, it returns to the liquid cavity at the bottom of the phase change radiator, thereby realizing a refrigeration cycle. [0003] However, due to the fixed gas flow direction of the current phase-change liquid-cooled radiator of this structure, the phase-change cold plate is designed with a vertical cooling flow channel, and the outlet of the gaseous cooling medium is designed above the flow channel. When the cold plate is vertically When the cooling table c...

Problems solved by technology

[0003] However, due to the fixed gas flow direction of the current phase-change liquid-cooled radiator of this structure, the phase-change cold plate is designed with a vertical cooling flow channel, and the outlet of the gaseous cooling medium is designed above the flow channel. When the cold plate is vertically When the cooling table cover is rotated 90° clockwise, it will not work properly because the gas cannot be discharged, and some users cannot install it vertically upward due to space constraints, so the phase change fluid with this structure cannot be used cold radiator

[0004] The phase-change liquid-cooled radiator with the above-mentioned structure still has the problem that the fluid flow in the parallel flow channel is relatively stable, and the convective heat transfer coefficient of the liquid is relatively poor.
