Description

Technical field

The present invention relates to the field of communications, and in particular to a container data center system and a cooling method. Background technique

In recent years, with the vigorous development of the communication and information industry, especially the emergence of cloud computing, the data center has shown a large-scale development trend. The emergence of containerized data centers is adapting to the market's demand for data centers, and has been used more and more in recent years. Different from the traditional data center, the data center of the container is equipped with pre-installed basic equipment such as refrigeration and power supply. It can be debugged on site and powered on. It can be deployed quickly where needed, the construction cost is significantly reduced, and the deployment and construction period is greatly shortened.

Current container data centers use repellent liquid cooling technology. The equipment and communication technology (ICT) equipment in the equipment machine generates a large amount of heat. After the cold air absorbs the heat generated by the ICT equipment, the temperature rises to become hot air, and the hot air enters the hot channel. Subsequently, the hot air in the hot aisle enters the side-mounted liquid to be cooled. In the liquid cooling, the hot air exchanges heat with the cold water (or other liquid cold source), and the temperature of the hot air is reduced to cold air, and the cold air then enters. Cold aisle. There are also some types of modular data centers that use different types of refrigerating liquid cooling, but in principle they are the same. ICT equipment such as servers use air cooling. The cold air absorbs the heat generated by the ICT equipment and becomes hot air. The hot air is air- After the liquid heat exchanger is cooled, the temperature is lowered to become cold air.

The liquid in the air-to-liquid heat exchanger is usually supplied by a cold water system, which is usually composed of a chiller, a pump, necessary heat exchangers, piping and control systems. The cold water system can be a traditional large chilled water system or a separate container, even in the same container as the ICT equipment.

In existing container data centers, the heat density of air cooling is low; and in order to drive Gas usually requires a fan to be installed, and the fan consumes a lot of energy and causes a series of problems such as noise. In addition, existing container data centers require a cold water system or an air conditioning system to provide a cold source, and a chiller or air conditioner in a cold source system consumes a large amount of electrical energy.
