Abstract

The invention provides a liquid-air dual-supply cold source module combining natural cooling and mechanical refrigerating and a control method thereof. The cold source module comprises a closed cooling tower and a cold water machine. The cold source module can be used for simultaneously providing high-temperature freezing water and low-temperature freezing water, and three running modes of single-supply liquid cooling, single-supply air cooling and liquid-air dual supply are switched according to actual demand. Through adjusting running states of an electrically-operated valve and equipment bya temperature sensor, a natural cold source is utilized to the greatest extent, so that the energy consumption of the system is reduced; with the design of an integrated module, installation and capacity expansion are facilitated, and subsequent maintenance is also facilitated; the modules are backup to each other, the running reliability of the system is improved; and two different types of coldwater (such as 35 DEG C natural cooling water and 7 DEG C mechanical refrigerating water) can be provided by the cold source module, a single form of cold water can be independently supplied, two forms of cold water also can be simultaneously supplied, and different application working conditions are met.

Description

technical field [0001] The invention relates to the technical field of heat dissipation for servers, in particular to a cold source module combining natural cooling with a dual supply of liquid and gas and mechanical refrigeration and a control method thereof. Background technique [0002] Under normal operating conditions, the temperature of the CPU chip itself, which is the main component to be cooled in the server, only needs to be kept between 60 and 80°C. The only way to ensure sufficient heat dissipation is to reduce the temperature of the air. According to the recommendation of the national standard, the temperature of the cold air in the computer room should be 24°C, and to maintain the indoor temperature of 24°C throughout the year must be achieved through mechanical refrigeration. The mechanical cooling method throughout the year results in huge energy consumption of the cooling system, which can account for about 45% of the total energy consumption of the data cen...
