Abstract: An immersion dual-cycle multi-mode liquid cooling regulation system and method for a data center comprises data center cabinets, a microchannel condensation heat exchanger, a plate heat exchanger, waste heat recovery devices, a cooling water storage tank, a fluorinated liquid storage tank, a liquid pump, a fluorinated liquid, pipelines, and pipeline valves. The system switches between single-phase and two-phase circulation loops according to the working power consumption of a server and the thermophysical property of a cooling working medium, and realizes flexible adjustment and control according to the cooling demand of the cabinet, the load magnitude and the working environment, thus avoiding the waste of resources caused by different loads in the data center; and cooling water flows through the waste heat recovery devices to recover heat, to reduce the electricity consumption of the system and greatly improve the utilization efficiency of cooling capacity.
