Abstract
This electronic apparatus 100 comprises a heating element 20, and a case 30. The case 30 has an opening hole 31. In order that a refrigerant COO will be sealed between the case 30 and the heating element 20, the outer periphery part of a first heating element external surface 21, which is the external surface of the heating element 20, is attached to the outer periphery part of the opening hole 31. Also, the refrigerant COO is a refrigerant that is capable of phase change from a liquid refrigerant LP-COO to a gas phase refrigerant GP-COO. As a result, it is possible to more efficiently cool the heat of the heating element 20.
Claims14
An electronic apparatus comprising:
- a heat-generating body;
- and
- an enclosure including an opening, an outer circumferential part of a first heat-generating body outer surface being an outer surface of the heat-generating body being mounted on an outer circumferential part or an inner circumferential part of the opening in such a way that a coolant that can undergo a phase change to a liquid-phase coolant and a gas-phase coolant is hermetically sealed between the enclosure and the heat-generating body.
