Immersion type liquid cooling and circulating air cooling combined server cabinet heat dissipation system

Abstract

The invention relates to an immersion type liquid cooling and circulating air cooling combined server cabinet heat dissipation system, which comprises a cabinet body, a server module, a heat exchangermodule, a static pressure box module, a liquid pipeline system and a temperature control system. Liquid circulating working medium is adopted to cool a server processor, and gas circulating working medium (air ) is adopted to cool other heating elements. The heat exchanger module is arranged at the bottom of the cabinet, and comprises a first-stage heat exchanger and a second-stage heat exchangerand cools the liquid circulating working medium and the air respectively with low-temperature refrigerant water serving as a cold source. A static pressure box and a windshield form a closed air flowchannel, so that the thermal pollution to the external environment of the cabinet is reduced. According to the invention, independent cooling is carried out on different heating density areas of theserver. Sealing immersion type liquid cooling is adopted for high heating areas, and circulating air is adopted for cooling low heating areas. The heat dissipation efficiency of the system is effectively improved, the generation of local hot spots is inhibited, and the energy consumption of a refrigeration system is reduced.

Description

technical field [0001] The invention relates to a heat dissipation and cooling system for information technology (IT) equipment, in particular to a server cabinet heat dissipation system combining submerged liquid cooling and circulating air cooling. Background technique [0002] The Internet Data Center (IDC) computer room has become an important part of the national economic development, and is the infrastructure for promoting the informatization and digitization of the national science and technology industry. With the increase in the scale of data centers and the popularity of blade servers with high heating power, the heat density of cabinets has increased sharply. On the one hand, the heat dissipation of high heat density servers has become an urgent problem to be solved. Downtime will cause huge losses; on the other hand, the power of cooling equipment required for heat dissipation will increase exponentially, further increasing the energy consumption of the data cent...

AI Technical Summary

Problems solved by technology

The cooling efficiency of the traditional heat dissipation method is low, and there are problems such as local hot spots and uneven heating and cooling in the cabinet

The processor, the main heating element in the server, releases a huge amount of heat. In order to take this part of the heat away, it is usually required to reduce the air supply temperature of the air conditioner and increase the air supply volume, which will cause the components with low heat generation on the server to be over-cooled state, resulting in waste of energy
