Background

As the global demand for data exchange has increased, so has the demand for servers. To do so, the servers consume more power exponentially, and therefore generate more heat. The heat generated by the server is more, and the development of the communication data communication equipment center is always restricted by the conventional precision air conditioner due to the problem of power consumption, and the effective cooling of the electronic components in the data center has been the focus of attention.

Existing equipment utilizes controlled fluid cooling circuits to cool components within a data center to remove waste heat generated by electronic components to maintain the components within allowable operating temperature limits. The conventional CDU is limited in installation and use due to factors such as volume, floor space, and spatial layout. In addition, when the CDU is applied to a plurality of server cabinets, a part of lines are in fault, and the reliability of use is further influenced.
