Data center tail end precise cold supply system and method based on field synergy principle

Abstract

The invention provides a data center tail end precise cold supply system and method based on the field synergy principle. The system comprises an airflow adjusting device and a control device. The air flow adjusting device is installed below the data center cabinet, serves as an inlet of a cold channel of the data center cabinet, is connected with the control device and is used for adjusting cold supply air flow sent to the data center cabinet based on a control signal of the control device. The control device is connected with the airflow adjusting device and used for obtaining the load capacity of the data center cabinet, calculating the cooling capacity according to the field synergy principle and sending a control signal to the airflow adjusting device based on the cooling capacity. The air flow adjusting device and the control device are convenient to install and can be installed on the premise that the structure of a cooling system of the data center is not changed; coupling analysis of a flow field and a temperature field is carried out through a control device according to the field cooperation theory, the wind direction and the wind quantity are calculated according to the optimal cooperation angle, cooling is supplied as needed, the local hot spot problem is solved, and the cooling capacity utilization rate is increased.

Description

technical field [0001] The invention belongs to the field of heating, ventilating and air conditioning, and in particular relates to a precise cooling system and method at the end of a data center based on the principle of field coordination. Background technique [0002] With the rapid development of 5G technology, cloud computing, and the Internet of Things, the construction and development of data centers are also getting faster and faster. The increase of servers with high heat flux density puts greater pressure on the heat dissipation of the computer room. How to optimize the airflow organization of air-cooled data centers and improve energy utilization efficiency is a widely concerned issue. The closed cold aisle with underfloor air supply is currently the most widely used form of air supply in computer rooms. However, this method has uneven air supply, which may easily lead to hot spots in some areas of the computer room and affect the efficient operation of the coo...

Problems solved by technology

However, this method has uneven air supply, which can easily lead to hot spots in some areas of the computer room and affect the efficient operation of the cooling system in the computer room.

Aiming at the problem of uneven air supply and poor coordination in data centers, many studies have focused on the optimization of airflow organization in data centers. It adopts variable opening ratio floor air supply and uses trapezoidal static pressure box, etc.

[0003] However, the above method can only solve the problem of uneven air volume at the outlet of the air-cooled data center floor static plenum, and cannot realize on-demand adjustment, nor can it improve the air volume difference at the server inlet in the vertical direction in the cold aisle above the floor, and there are still The coordination between the temperature field and the velocity field is poor, and local hot spots cannot be dealt with, etc.
