Cabinet cooling system and control method thereof

Abstract

The invention discloses a cabinet cooling system and a control method thereof, relates to the technical field of communication equipment, and aims to improve the utilization rate of cold liquid cooling capacity, reduce the energy loss of cold liquid and improve the energy consumption ratio of the cabinet cooling system. The cabinet cooling system comprises a cabinet, a liquid supply pipe, a liquid return pipe and a heat exchanger, the cabinet comprises a plurality of server box bodies arranged at intervals in the vertical direction, liquid distribution boxes, supports and liquid collection trays are arranged in the server box bodies at intervals from top to bottom in the vertical direction, the bottoms of the liquid distribution boxes are provided with a plurality of pressure spray heads, the supports are used for installing servers, and the liquid collection trays are used for installing the servers. The density distribution of the plurality of pressure nozzles adapts to the load of each component of the server; the heat exchanger, the liquid supply pipe, the liquid distribution box, the liquid collection disc, the liquid return pipe and the heat exchanger are sequentially communicated to form a cold liquid circulation loop. The server cooling device is used for cooling the server.

Description

technical field [0001] The invention relates to the technical field of communication equipment, in particular to a cabinet cooling system and a control method thereof. Background technique [0002] With the innovation and development of distributed computing architectures such as artificial intelligence, cloud computing, and big data, the density of cabinets installed in computer rooms continues to rise. The indoor baseband processing unit (English: Building Base band Unit, referred to as: BBU) installed in the cabinet will generate a lot of heat during operation. In order to ensure the safe and stable operation of the BBU equipment, it is necessary to set up a cooling system to cool the BBU equipment. Common cooling systems include the air-conditioning system in the equipment room and the fans installed in the cabinets. The air-conditioning system cools the air in the equipment room. The fans allow cold air to enter one side of the cabinet and exhaust hot air to cool the BB...

AI Technical Summary

Problems solved by technology

[0004] However, in the submerged liquid cooling system provided by the prior art, the supply of cooling liquid to the cooling system is relatively large, and the loss of cooling liquid during transportation is also relatively large.

Moreover, since each component of the BBU equipment generates different amounts of heat, for example, the main control transmission module, channel processing board, and communication power supply module of the BBU equipment have a large load and generate more heat, and the general-purpose extended transmission processing unit, lightning protection unit, etc. The load is small, the heat generation is less, and the utilization rate of the cooling capacity of the cooling liquid is different for each component. The cooling capacity utilization rate of the cooling liquid of the component with less heat generation is lower, and the energy efficiency of the cooling system is lower.
