Single-phase immersed liquid cooling cabinet

Abstract

The invention discloses a single-phase immersed liquid-cooled cabinet. A cabinet shell of the liquid-cooled cabinet is provided with a bottom plate and an containing space formed on the bottom plate; the first partition plate divides the containing space into a backflow groove and a bearing groove, the second partition plate further divides the bearing groove into an equipment area and a liquid supply area, the equipment area is close to the backflow groove, the liquid supply area is far away from the backflow groove, then the liquid supply pipeline is used for allowing cooling liquid to flow into the liquid supply area, and the liquid return pipeline is used for allowing the cooling liquid to flow out of the backflow groove; a cooling liquid channel is arranged between one end of the second partition plate and the bottom plate, and the other end is higher than the first partition plate; therefore, the cooling liquid firstly flows into the liquid supply area from the liquid supply pipeline, the liquid supply area is communicated with the equipment area for bearing the electronic equipment, the cooling liquid overflows to the reflux tank through the first partition plate after heat exchange with the electronic equipment in the equipment area and then flows out of the liquid cooling cabinet through the liquid return pipeline, and liquid cooling heat dissipation of the electronic equipment is realized through such circulation. Therefore, the technical problem of high energy consumption of the circulating pump is solved.

Description

technical field [0001] The invention relates to the technical field of liquid cooling and heat dissipation, in particular to a single-phase submerged liquid cooling cabinet. Background technique [0002] In some fields, electronic equipment has gradually applied liquid cooling heat dissipation technology for heat dissipation. A common liquid cooling heat dissipation method is single-phase immersion liquid cooling heat dissipation. In this liquid cooling heat dissipation method, there are coolant inlets and outlets. Liquid-cooled cabinets are usually used to carry several electronic devices. In this way, the cooling liquid flows into the liquid-cooled cabinet from the inlet and passes through the electronic devices, and flows out from the outlet after exchanging heat with the electronic devices. [0003] In the prior art, the above-mentioned liquid-cooled cabinet is usually provided with a coolant inlet at the bottom and a coolant outlet at the top, so that the low-temperatur...
