Classification code: H05K7/20.

Patent Abstract: The present invention provides a liquid cooling heat dissipation system and data center, relating to the field of cooling technology. The liquid cooling system includes an immersed liquid cooling blade box, a heat exchanger, and a liquid storage buffer tank, connected in a loop via pipelines. The immersed liquid cooling blade box is used to hold the motherboard to be cooled, which is immersed in the first refrigerant. The heat exchanger, buffer tank, and immersed blade box are arranged at different heights, allowing the first refrigerant to circulate in the loop by gravity. In this system, the first refrigerant relies on gravity to circulate, meaning no pumps or other power devices are needed. The pressure difference generated by the height difference of the refrigerant level drives the circulation, effectively reducing electrical power consumption and achieving energy savings.
