A cooling cabinet and cooling system combining liquid cooling and air cooling

Abstract

The invention discloses a cooling cabinet combined with liquid cooling and air cooling and heat dissipation, which comprises the following components: a cabinet body with a cabinet door; a liquid cooling server, which is arranged inside the cabinet body, and the liquid cooling server is respectively connected to a main liquid inlet pipe and the main liquid outlet pipe; the first plate heat exchanger is arranged on the side of the liquid-cooled server, and the first plate heat exchanger is respectively connected to the first liquid inlet pipe and the first liquid outlet pipe; the second plate heat exchanger is arranged on the On the side of the liquid-cooled server opposite to the first plate heat exchanger, the second plate heat exchanger is respectively connected to the second liquid inlet pipe and the second liquid outlet pipe; and multiple cross-flow fans, multiple cross-flow fans are set On opposite sides of the liquid-cooled server, the heat generated by the liquid-cooled server is respectively transferred to the first plate heat exchanger and the second plate heat exchanger for cooling. The invention also discloses a cooling system. The cooling cabinet and the cooling system proposed by the present invention can realize the combination of liquid cooling and air cooling and heat dissipation, and improve the efficiency of heat dissipation.

Description

technical field [0001] The invention relates to the field of heat dissipation, more specifically, to a cooling cabinet and a cooling system combining liquid cooling and air cooling for heat dissipation. Background technique [0002] Taking a certain type of domestic complete cabinet server (high temperature index is 35°C) as an example, its peak power consumption is 24kW, it adopts an open, air-cooled cooling scheme, and its maximum noise is 85dB. Limited by the noise level, 25kW is considered to be the heat dissipation limit of the open air-cooled architecture. With the improvement of system integration and system power consumption, the power consumption level of cabinets in typical scenarios such as high-performance computing and high-density deployment has increased to more than 30kW. [0003] As for the noise level, it is generally considered quiet and suitable below 40dB, 50-55dB is recommended for living and office conditions, and below 60dB is considered not to affec...

AI Technical Summary

Problems solved by technology

The immersion cooling system can reduce the noise to 40dB, but it is limited by sealing, load-bearing and node / server maintenance requirements, etc. High-density, cabinet-level immersion systems need to adopt a horizontal solution. Compared with traditional vertical cabinets, this solution It has the greatest impact on the layout of the computer room and the worst compatibility with traditional equipment
