The indirect evaporative cooling equipment adopts the at least two heat exchangers and is provided with at least two heat exchange channels, so that the heat exchange efficiency is improved.

Description

technical field [0001] Embodiments of the present invention relate to but are not limited to the technical field of heating and ventilation equipment, and in particular, relate to an indirect evaporative cooling equipment. Background technique [0002] With the rapid development of my country's Internet and communication industries, the total number of big data centers in my country has increased year by year, exceeding 400,000. In order to save energy and protect the environment, multiple departments have jointly formulated the "National Green Data Center Pilot Work Plan", which requires the establishment of green big data centers in key areas to reduce the overall PUE (Power Usage Effectiveness, total equipment energy consumption of data centers and IT equipment) of big data centers. ratio of energy consumption). The main features of the green big data center are: (1) low PUE; (2) recycling of water resources; (3) multi-directional use of natural cold sources. Evaporativ...

Problems solved by technology

Among them, the middle layout of the vertical core requires a large space and low heat transfer efficiency; the vertical core has a moderate space requirement for the top layout, and the heat transfer efficiency is moderately high, but the flow direction of the core is not easy to control, and the spray loss is relatively large; while the diamond core The heat transfer efficiency of the body layout is low, and the spray loss is relatively large. The above schemes have defects and need to be improved.
