1. A closed circulating water cooling apparatus, comprising:
an internal cooling apparatus, a plate heat exchanger and an ice thermal-storage auxiliary cooling apparatus, wherein the internal cooling apparatus comprises an internal cooling circulation pump and an air cooler; the ice thermal-storage auxiliary cooling apparatus comprises an external cooling circulation pump and an ice thermal-storage apparatus, wherein heat is exchanged between internal cooling water in the internal cooling apparatus flowing through the plate heat exchanger and external cooling water in the ice thermal-storage auxiliary cooling apparatus flowing through the plate heat exchanger), wherein the internal cooling apparatus further comprises a first loop valve and second loop valves; in the state that the first loop valve is opened and the second loop valves are closed, the air cooler and a device to be cooled form a first loop in which the internal cooling water circulates; in a state that the first loop valve is closed and the second loop valves are opened, the device to be cooled, the air cooler and the plate heat exchanger form a second loop in which the internal cooling water circulates; a circulation loop of the external cooling water is formed by the plate heat exchanger and the ice thermal-storage apparatus.
