Claim 0:
1. An immersion dual-cycle multi-mode liquid cooling regulation system for a data center, comprising a data center cabinet array, a microchannel condensation heat exchanger, a plate heat exchanger, a first waste heat recovery device, a second waste heat recovery device, a fluorinated liquid storage tank, a second cooling water drive pump, a cooling water storage tank, a fluorinated liquid drive pump, a first cooling water drive pump, an external back-clip fan, a single-phase loop cooling water valve and a two-phase loop cooling water valve, wherein the data center cabinet array consists of a plurality of data center cabinets, the data center cabinets are connected with the plate heat exchanger through a fluorinated liquid outlet pipeline, an outlet end of the plate heat exchanger is connected with the fluorinated liquid storage tank through the fluorinated liquid drive pump and a fluorinated liquid outlet pipeline valve, an upper part of the data center cabinet is connected with the microchannel condensation heat exchanger through a fluorinated liquid vapor outlet pipeline, a middle part of the data center cabinet communicates with the fluorinated liquid storage tank, and an upper part of the fluorinated liquid storage tank communicates with the microchannel condensation heat exchanger, thereby forming a working loop of a fluorinated liquid;
an upper part of the cooling water storage tank returns to a lower part of the cooling water storage tank through the two-phase loop cooling water valve, the first cooling water drive pump, the microchannel condensation heat exchanger and the first waste heat recovery device in sequence, thereby forming a working loop of cooling water; in addition, a middle part of the cooling water storage tank returns to the cooling water storage tank through the second waste heat recovery device, the second cooling water drive pump, the plate heat exchanger and the single-phase loop cooling water valve, thereby forming a second working loop of the cooling water; and the circulation of the cooling water and the circulation of the cooling fluorinated liquid are independent of each other, solely serving the purpose of heat exchange therebetween.
