Method and device for cooling machine cabinet

Abstract

The invention provides a method for cooling a machine cabinet, which comprises the following steps: injecting cold air into a machine cabinet from the lower part of the machine cabinet; delivering the cold air bottom-up in the machine cabinet to cool heating components in the machine cabinet; discharging hot air with high temperature after heat exchange from the upper part of the machine cabinet; cooling the discharged hot air; and injecting the cold air generated through cooling the hot air into the machine cabinet from the lower part of the machine cabinet, and cyclically cooling the machine cabinet. The invention also provides a device for cooling the machine cabinet, which comprises a machine cabinet which is provided with a hot air outlet on the upper part and a cold air inlet on the lower part, a blowing unit which is used for delivering the cold air injected from the cold air inlet bottom-up from the lower part of the machine cabinet, and a liquid cooling unit which is used for cooling the hot air discharged from the hot air outlet and injecting the cold air into the machine cabinet from the cold air inlet. The invention adopts the features that cold air subsidises and hot air rises based on the water cooling mode, and organically combines vertical cooling and water cooling, thereby effectively improving the cooling effect.

Description

technical field [0001] The invention relates to a cooling method and device for a cabinet. Background technique [0002] At present, for the wide application of blade servers, the problem of high thermal density heat dissipation is an urgent problem to be solved. When the heat generated inside the cabinet exceeds 20KW, the traditional air cooling method can no longer meet the heat dissipation requirements of the system. [0003] At present, for the problem of high heat density in the computer room, many manufacturers have proposed corresponding solutions, using water cooling methods to dissipate heat from high-density cluster systems, and these methods have achieved relatively ideal results in the actual application process. [0004] However, most of the current water-cooling methods use horizontal air supply. In this cooling method, the wind direction cannot guarantee a strict horizontal state when supplying air to the server, because the cold air enters in front of the ser...

Problems solved by technology

[0004] However, most of the current water-cooling methods use horizontal air supply. In this cooling method, the wind direction cannot guarantee a strict horizontal state when supplying air to the server, because the cold air enters in front of the server, and with the airflow Flowing into the back end of the server, the airflow extends upward as the temperature continues to rise, resulting in a circulation that cannot guarantee a strictly horizontal state, reducing the cooling effect
