摘要： A cooling device that can reduce heat resistance by improving a heat exchange action of a condensation tube, and can exhibit excellent cooling characteristics, and a cooling system using the cooling device are provided. The cooling device includes a container to which at least one heating element is thermally connected, a primary refrigerant sealed inside the container, a condensation tube through which a secondary refrigerant flows and which penetrates through a gaseous phase portion inside the container, and a porous member provided at an outer surface of the condensation tube.

摘要： There is provided a flat heat pipe that is not easily deformed in spite of a reduction in thickness and can maintain high heat transport capacity.
A flat heat pipe 100 includes a container 130 in which a cavity 130S is formed by plates 110 (110a, 110b) made of metal and disposed substantially in parallel with each other, working fluid that is enclosed in the cavity 130S, and a wick structure 150 that is inserted into the container. The wick structure 150 includes a first sheet-like member 140, and hollow protruding portions 170 protruding in a height direction of the container 130 are formed on the first sheet-like member 140.
