Cabinet and air flow control method thereof

Abstract

The invention discloses a cabinet comprising a cabinet body. An air-conditioner used for cooling is arranged outside the cabinet body. An air blowing channel and an air returning channel connected with an air blowing port and an air returning port respectively are arranged on the cabinet body. A first air flow control device is arranged at the connection position of the air blowing channel and the cabinet body, and a second air flow control device is arranged at the connection position of the air returning channel and the cabinet body. The cabinet further comprises a temperature detecting device and a control module which is connected with the temperature detecting device, the first air flow control device and the second air flow control device. By the design, a sealed cooling air circulation loop can be formed between the cabinet body and the air-conditioner, load area of the air-conditioner is reduced, and cooling time of the air-conditioner is reduced; and air flow control devices are arranged at connection positions of the cabinet body with the air blowing channel and the air returning channel, air blowing and air returning are realized accurately, the air flow can be adjusted in real time according to temperature changes inside the cabinet body, and good protection affection to working environment of inter parts of the cabinet body is realized.

Description

technical field [0001] The invention relates to the technical field of machine room refrigeration, in particular to a cabinet and a method for precisely controlling the air volume of the cabinet. Background technique [0002] According to statistics, in the huge energy consumption composition of the computer room, air conditioning energy consumption accounts for more than 40%. In order to ensure the long-term reliable operation of the server, the server room is usually equipped with 24-hour air conditioning to reduce the temperature of the room. At present, most of the computer room cooling strategies are to reduce the temperature of each cabinet and the equipment installed in the cabinet by reducing the overall temperature of the computer room and installing fans in the cabinets. [0003] The temperature of the cabinet is lowered by reducing the overall temperature of the computer room. The cold energy in the room needs to pass through the cabinet to transfer to the cabine...

Problems solved by technology

However, since this cabinet cooling system only controls the air volume through the sliding cover at the bottom of the cabinet, it cannot achieve precise control of the air volume, nor can it realize the real-time coordination between the temperature and the air volume, resulting in a great waste of cold air resources and reducing Cooling efficiency and resource utilization of the cabinet
