Description

TECHNICAL FIELD

[0002] The cabinet is widely used in the fields of data center, 5G communication base station and power distribution facility, and the environmental parameters such as temperature, humidity and cleanliness in the cabinet directly affect the safe and reliable operation and service life of the equipment in the cabinet. With the increasing heat generated by the equipment in the modern data center, 5G base station and high-power power distribution cabinet, the heat dissipation problem of the cabinet becomes more and more important. The traditional air ventilation cooling system and the environmental temperature control air conditioning system have been difficult to meet the high-power heat dissipation demand, resulting in problems such as overheating of the equipment in the cabinet, reduced performance and shortened service life. In order to solve these problems, more and more data center cabinets and 5G cabinets have begun to use water cooling systems.
