Abstract
A cooling device includes an evaporator. The evaporator includes a housing having a reserver, a wick and a groove member having a plurality of vapor flow channels through which the working fluid changed in phase from the liquid phase to the vapor phase flows. The groove member is constituted by alternately stacking two or more first metal plates coupled to the wick and two or more second metal plates disposed at a larger distance from the wick than that of the first metal plate. One vapor flow channels is formed between the first metal plates adjacent to each other at the wick side of the groove member. A dimension along the first direction is larger than a dimension along the second direction in a cross-sectional surface of the vapor flow channel when viewing the groove member along a direction perpendicular to both the first direction and the second direction.
