This application claims priority to Chinese Patent Application No. 202211741906.X filed on Dec. 30, 2022, in China National Intellectual Property Administration, the contents of which are incorporated by reference herein.
The subject matter herein generally relates to power management technologies, and specially relates to a power detecting circuit board and, a power detecting system, and an immersed liquid cooling tank.
With the development of the data center, the power density of a single cabinet in the data center is getting higher and higher, a traditional air cooling system can no longer meet the heat dissipation requirements of the data center, so it is gradually being replaced by a liquid cooling system. An immersion liquid cooling system is a type of liquid cooling system, and it is to directly immerse the load such as the server or heating element in the cooling liquid and package it in a liquid cooler tank, so that the flow circulation of the cooling liquid can take away the heat generated by the load. In addition, the immersion liquid cooling is a typical direct contact liquid cooling, which has higher heat dissipation efficiency and lower noise than other liquid cooling systems such as cold plate and spray liquid cooling and air cooling systems.
