A method of heat dissipation and cooling for high heat density cabinets in data centers

Abstract

The present invention discloses a heat dissipation and cooling method for high-heat density cabinets in a data center. According to the method, a large-temperature difference air conditioner end device used for cabinet cooling and cooled cabinets are encapsulated in a constructed object isolated from a machine room environment, so that heat transfer between the inner space of the building and the external machine room environment can be prevented; the large-temperature difference air conditioner end device used for cabinet cooling is arranged at one side of the cooled cabinets, or the large-temperature difference air conditioner end device is arranged between the two cooled cabinets; the large-temperature difference air conditioner end device for cabinet cooling and the cooled cabinets are connected with a control system; and the large-temperature difference air conditioner end device for cabinet cooling can realize automatic adjustment according to the control system. According to the heat dissipation and cooling method for the high-heat density cabinets in the data center of the invention, the inner surface area of a circulating liquid flowing pipeline is increased, so that the heat exchange area of single heat exchangers can be increased; and the heat exchangers are connected in series with one another, so that the length of the flowing path of a circulating liquid can be obviously increased, and a small-flow rate and inlet / outlet large-temperature difference operation mode of the circulating liquid can be realized.

Description

technical field [0001] The invention relates to the technical field of air-conditioning and energy-saving systems in data centers, in particular to a heat dissipation and cooling method for high heat density cabinets in data centers. Background technique [0002] A data center is a place where a large number of servers, storage devices, and network devices are gathered. It is a service platform for centralized processing, storage, transmission, exchange, and management of data information. The power consumption of the data center is mainly composed of three parts: information equipment, air-conditioning system and power supply and distribution system, among which the power consumption of the air-conditioning system accounts for about 40% of the total. With the rapid development of my country's information industry, data centers will show explosive growth, and their power consumption will increase exponentially, resulting in huge energy consumption. [0003] With the further...

Problems solved by technology

The chilled water supply temperature of the precision air conditioner in the existing machine room is low and the temperature difference between the supply and return water is small. The temperature difference between the supply and return water is usually 5°C. The energy efficiency of the main engine is low and it is not conducive to the full utilization of free natural cooling sources
