Abstract
A cooling device is provided with an evaporator, a condenser, a vapor pipe, and a liquid pipe. The evaporator includes a housing having a reservoir configured to retain a working fluid in a liquid phase flowing inside, a wick disposed in the housing, and transporting the working fluid in the liquid phase, and a groove member having a plurality of flow channels through which the working fluid changed in phase from the liquid phase to the gas phase flows, the groove member being coupled to the wick. The wick has a plurality of through holes which penetrate the wick along a first direction from the reservoir toward the groove member, the through holes being configured to transport the working fluid in the liquid phase retained in the reservoir in the first direction.
