The computer cooling device 2 includes a pump unit 3, a refrigeration unit 4, and a backup refrigeration unit 5. A pump 6 and a backup pump 7 are arranged in the pump unit 3 to supply cold water to the CPU 1. The refrigeration unit 4 includes a compressor 8a, a condenser 9a, a blower 10a, and an expansion valve 1
A refrigeration cycle composed of 1a and an evaporator 12a is arranged, and the evaporator 12a produces cold water to be sent to the CPU 1. The backup refrigeration unit 5 also has the same refrigeration cycle as the refrigeration unit 4.

Cold water is supplied to U1 to remove the heat generated by the CPU 1, and the warmed cold water returns to the computer cooling device 2 again. Here, the backup pump 7 is on standby in preparation for an abnormal stop of the pump 6. The return water from CPU1 is the evaporator 1
2a and 12b are entered, the return water is cooled by the refrigeration cycle in the refrigeration unit 4, and the flow returns to the pump 6 again to supply the cold water to the CPU 1. Further, the backup refrigeration unit 5, like the backup pump 7, stands by in preparation for an abnormal stop of the refrigeration unit 4.

First, when the cold water temperature at startup is lower than the CPU operable water temperature, the pump 6 and the backup pump 7 are simultaneously operated to raise the water temperature to the CPU operable water temperature by heat generation of the pump. As a result, as shown in FIG. 2A, in the present invention, it becomes t 2 as compared with the time t 1 to reach the CPU operable water temperature by the operation of one conventional pump,
It is possible to shorten the CPU startup time. If the cold water temperature at startup is higher than the CPU operable water temperature, the refrigerating unit 4 and the backup refrigerating unit 5 are used.
To cool the cold water rapidly. As a result, as shown in FIG. 2B, in the present invention, as compared with the time t 3 required to reach the CPU operable water temperature due to the operation of one conventional refrigeration unit, the time is reduced to t 4 , and the CPU startup time is reduced. It can be shortened.
