Title:
COOLING DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/209138
Kind Code:
A1
Abstract:
The present invention provides a cooling device which makes it possible, even when reduced in size, to prevent attachment of droplets of primary refrigerant sealed in a container onto a condensation pipe in the container, and to prevent dry-out of a liquid-phase primary refrigerant. The cooling device is provided with: a container to which at least one heating body is thermally connected; a primary refrigerant sealed in the container; and a condensation pipe which penetrates through a gaseous-phase portion in the container and in which a secondary refrigerant circulates. The heating body is thermally connected to a portion, or to a vicinity thereof, of an outer surface of the container in which the liquid-phase of the primary refrigerant is present. A container inner surface area-increasing portion for increasing the area of contact with the liquid-phase of the primary refrigerant is formed on an inner surface of the container to which the heating body is thermally connected. At least a portion of the container inner surface area-increasing portion is immersed in the liquid-phase of the primary refrigerant. A plate-like member is provided which includes a shielding portion positioned over the container inner surface area-increasing portion in the direction of gravity and under the condensation pipe in the direction of gravity, at least a part of the shielding portion not being immersed in the liquid-phase of the primary refrigerant. The plate-like member is provided with a support portion extending from the shield portion in a part of a periphery of the container inner surface area-increasing portion along an orthogonal direction to the direction of gravity.
