Claim 7:
8. An immersion dual-cycle multi-mode liquid cooling regulation method of the regulation system according to claim 1, wherein when the dual-cycle multi-mode liquid cooling regulation system only works in a single-phase circulation loop, a fluorinated liquid vapor pressure relief valve, the two-phase loop cooling water valve and the first cooling water drive pump are closed, the fluorinated liquid outlet pipeline valve is opened, and the fluorinated liquid outlet pipeline is opened; when a cold source of the whole cycle is air where the data center cabinet is located, the single-phase loop cooling water valve is closed, the system works in an environmental cooling mode, and the fluorinated liquid flows into the plate heat exchanger under gravity, and transfers heat to external air in the flowing process; when the cold source of the whole cycle is cooling water, the single-phase loop cooling water valve is opened, the system works in a single-phase cooling mode, the cooling water in the cooling water storage tank automatically flows into the plate heat exchanger under gravity, the cooling water and the fluorinated liquid exchange heat in the plate heat exchanger, and the cooling water receiving heat through the plate heat exchanger flows through the second waste heat recovery device to recover heat and then is pumped into the cooling water storage tank to complete a cooling water single-phase cooling cycle; and the fluorinated liquid outlet pipeline of the plate heat exchanger is connected with the fluorinated liquid storage tank, and the cooled fluorinated liquid is propelled by the fluorinated liquid drive pump and flows back into the fluorinated liquid storage tank to replenish the supply of fluorinated liquid in the data center cabinet.
