A cooling liquid distribution device and liquid cooling cabinet

Abstract

The invention relates to the technical field of heat dissipation of electronic equipment, and discloses a cooling liquid distribution device and a liquid-cooled cabinet. The cooling liquid distribution device includes a liquid-distributing part, and the liquid-distributing part is arranged at the bottom of the cabinet of the liquid-cooled cabinet, wherein: The surface of the liquid part is provided with a plurality of liquid distribution holes along the arrangement direction of the electronic equipment in the cabinet; there is a liquid inlet in the liquid distribution part, and the liquid inlet is used to communicate with the liquid inlet pipe of the liquid cooling cabinet; the inner edge of the liquid distribution part is far away from the The direction of the liquid inlet is layered with multi-level flow channels, each level of flow channel includes at least one branch, and the number of branches contained in the multi-level flow channel increases step by step, after the cooling liquid passes through each level of flow channel in turn Flow out from multiple liquid separation holes. In the above-mentioned embodiment, the cooling liquid forms multiple streams of fluids with close flow rates after passing through multi-stage splitting, and enters the electronic equipment through the liquid separation hole, thereby effectively reducing the difference in the flow rate that finally enters each electronic equipment, so that each electronic equipment The heat dissipation effect of the equipment is close, thereby reducing the design margin of the cooling liquid.

Description

technical field [0001] The invention relates to the technical field of heat dissipation of electronic equipment, in particular to a cooling liquid distribution device and a liquid cooling cabinet. Background technique [0002] With the development of technology, the power consumption of electronic equipment is increasing, and simple air cooling can no longer meet the heat dissipation requirements in many cases. Liquid cooling technology has emerged and continues to develop. In the future, the liquid cooling market will continue to expand. Among them, immersion liquid cooling has become a new favorite in liquid cooling due to its advantages of high efficiency, energy saving, and low construction cost. [0003] In a liquid-cooled cabinet with multiple electronic devices, the electronic devices are arranged side by side in the cabinet, and the external low-temperature cooling liquid enters the cabinet through the liquid inlet. In the cabinet, the cooling liquid flows into each ...

AI Technical Summary

Problems solved by technology

The cooling liquid is usually a liquid with good insulating properties such as fluorinated liquid, silicone oil, and synthetic oil. It has high viscosity and density, and it will generate greater resistance when flowing in the cabinet. The less coolant for electronic equipment, the greater the difference in coolant flow among electronic equipment located in different positions of the same cabinet, which in turn leads to greater differences in the heat dissipation of each electronic equipment; at the same time, in order to ensure good Heat dissipation effect, the electronic equipment with the minimum flow rate also needs sufficient heat dissipation, so the total volume of coolant entering the system is often estimated according to the maximum flow demand, so it is forced to design a large design margin, which also causes a waste of some resources

[0004] At present, the research on the uniformity of submerged liquid cooling fluid mainly focuses on the improvement and control of the cabinet structure. Improving the flow uniformity through structural improvement on the cabinet is not only cumbersome but also effective. Starting from the control aspect, it is also difficult to control Very large and costly issues
