Abstract
A cooling device includes: a container in which a refrigerant is sealed; an evaporating part that evaporates the refrigerant in a liquid phase by heat reception inside the container; a condensing part that condenses the refrigerant in a gas phase by heat dissipation inside the container; and a plate-shaped or block-shaped flow path member in which a plurality of flow paths configured to transport the refrigerant in a liquid phase from the condensing part to the evaporating part by surface tension inside the container is formed in parallel.
Claims5
A cooling device comprising:
- a container in which a refrigerant is sealed;
- an evaporating part that evaporates the refrigerant in a liquid phase by heat reception inside the container to generate the refrigerant in a gas phase;
- a moving region provided along an upper surface of the container and in which the refrigerant in the liquid phase moves;
- a condensing part provided in the moving region and that condenses the refrigerant in the gas phase by heat dissipation inside the container to generate the refrigerant in the liquid phase;
- and
- a plate-shaped or block-shaped flow path member provided between a lower surface of the container and the moving region and in which a plurality of flow paths configured to transport the refrigerant in a liquid phase from the condensing part to the evaporating part by surface tension inside the container is formed in parallel,
- the evaporating part evaporates the refrigerant in the liquid phase, which is transported from the plate-shaped or block-shaped flow path, in column members which extend from the lower surface of the container to the upper surface of the container.
