Description

[Brief explanation of drawings]

Figure 1 is a diagram showing one embodiment of this invention, Figure 2
The figure shows a conventional example, and FIG. 3 is a detailed view showing the operating state of the cooling device for electronic equipment. In the figure, 1 is a flat cold plate, 2 is a solenoid valve, 3 is an electronics module, 4 is a refrigerant flow path, 5 is a pump, 6 is a tank, and 7 is an opening solenoid valve. Note that the same reference numerals in each figure indicate the same or equivalent parts.

Claims (1)

[Scope of utility model registration request] In order to cool a plurality of electronics modules containing electronic components that require cooling, the electronics module is installed so that a flat plate surface is close to the surface of the electronics module, and has a refrigerant flow path inside, and the flat plate surface is A cooling device for electronic equipment comprising a flat cold plate having a thin wall structure that can expand due to an increase in pressure in a refrigerant flow path, and a pump and a reservoir tank for forcibly circulating a cooling medium such as water through the cold plate, a solenoid valve that is provided on the inlet and outlet piping through which the cooling medium of the flat cold plate flows, and that closes to separate the refrigerant flow path from the pump and tank when the pump is stopped; and the cooling medium of the flat cold plate. 1. A cooling device for electronic equipment, characterized in that a solenoid valve is provided on an outlet side through which the refrigerant flows, and opens the internal pressure of the refrigerant flow path to be equal to the atmospheric pressure when the pump is stopped.
