Abstract

The invention discloses a closed evaporative cooling cold water system for a data center. The system comprises a casing body. A wet channel, a dry channel, and a water tank are sequentially arranged from top to bottom in the casing body. The system further comprises a cabinet closed cold channel. A heat exchanger and an air return opening are arranged in order from bottom to top at the top of thecabinet closed cold channel. The wet channel is connected with the heat exchanger through a water pipe G1 and a water pipe G2 to form a closed pipeline. According to the closed evaporative cooling cold water system provided by the invention, the heat exchanger is placed on the cabinet closed cold channel; cold water flows in the coil of the heat exchanger; water cooling is used instead of traditional air cooling to achieve a better cooling effect; to a certain extent, the indoor occupied space is saved; two-stage cooling of return water is realized; finally cold water with lower temperature isacquired to cool down the cabinet of the data center; and compared with direct heat exchange and other indirect heat exchange, indirect evaporative cooling has a better cooling effect.

Description

technical field [0001] The invention belongs to the technical field of air conditioning equipment, and in particular relates to a closed evaporative cooling cold water system for a data center. Background technique [0002] With the rapid development of the Internet and the information industry, the world has entered the era of big data. According to the cooling characteristics and energy consumption characteristics of the data center, the use of natural cooling sources to cool down the computer room has become an important issue of energy saving and emission reduction. [0003] The energy consumption of the compressor in the traditional mechanical refrigeration system accounts for the largest proportion of the total energy consumption. When the system adopts natural cooling technology, it can achieve the purpose of saving energy and reducing consumption, so it has great potential in the application of data centers. [0004] Cooling tower cooling technology is an energy-sa...
