Description

Technical Field

[0002] With the rapid development of network technology and informatization, the demand for large server clusters such as data centers and server centers is increasing. Studies have shown that only 15% to 20% of the electricity consumed by data centers is used for computing, and 80% to 85% of the electricity is converted into heat energy. The heat emitted each year accounts for 2% of the country's energy consumption. The optimal operating temperature of a data center is 23°C. When the room temperature is higher than 30°C, the battery life of the server cluster will decrease, the failure rate of electrical components will increase, and the performance and operation of network equipment will be affected. The long-term operation of large server clusters in data centers generates a lot of heat. The temperature of the hot channel in a high-performance computer room can even reach 40°C.
