Claim 7:
8. The heat dissipation method for the two-phase flow active and passive multi-level data center cabinet cooling device according to claim 7, wherein when the condensate temperature monitored by the condensing unit temperature sensor (22) is lower than a high temperature threshold of the condensate, a condensate inlet temperature control valve (23) and a condensate outlet temperature control valve (24) are both closed, and the liquid pump (5) of the condensate system is closed;
when the condensate temperature monitored by the condensing unit temperature sensor (22) is higher than the high temperature threshold of the condensate, the condensing unit temperature sensor (22) sends a signal to open the condensate inlet temperature control valve (23) and the condensate outlet temperature control valve (24) and start the liquid pump (5) of the condensate system to continuously inject condensate into the cabinet condensing unit (3);
when the condensate temperature monitored by the condensing unit temperature sensor (22) is lower than a low temperature threshold of the condensate, and the condensate inlet temperature control valve (23), the condensate outlet temperature control valve (24) and the liquid pump (5) of the condensate system are all in an open state, the condensing unit temperature sensor (22) sends a signal, the liquid pump (5) of the condensate system is closed, and then the condensate inlet temperature control valve (23) and the condensate outlet temperature control valve (24) are also closed one after another.
