Abstract

An electronic equipment includes a refrigerant tank that contains a refrigerant, a plurality of electronic components immersed in the refrigerant of the refrigerant tank, and a refrigerant injection member including a plurality of injection holes to inject the refrigerant supplied from a refrigerant inlet so as to cause the refrigerant to flow between the plurality of electronic components, wherein opening areas of the injection holes of the refrigerant injection member are set to be larger as the injection holes are far from the refrigerant inlet.

Claims

1. An electronic equipment comprising:

a refrigerant tank that contains a refrigerant;

a plurality of electronic components immersed in the refrigerant of the refrigerant tank; and

a refrigerant injection member including a plurality of injection holes to inject the refrigerant supplied from a refrigerant inlet so as to cause the refrigerant to flow between the plurality of electronic components,

wherein opening areas of the injection holes of the refrigerant injection member are set to be larger as the injection holes are far from the refrigerant inlet.

2. The electronic equipment according to claim 1, further comprising:

a circuit board disposed inside the refrigerant tank to be electrically connected to the electronic components,

wherein the refrigerant injection member is disposed between the circuit board and the electronic components.

3. The electronic equipment according to claim 1, wherein at least one of the electronic components is a storage device.

4. The electronic equipment according to claim 1, wherein the refrigerant is an insulating inert liquid.

5. The electronic equipment according to claim 1, further comprising:

a dummy disposed in the refrigerant together with the electronic components, and including a closing unit configured to close the injection holes.
