COOLING DEVICE AND PROJECTOR
First Claim
1. A cooling device comprising:
- an evaporator configured to evaporate working fluid in a liquid phase with a heat transferred from a cooling target to change to the working fluid in a vapor phase;
a condenser configured to condense the working fluid in the vapor phase to change to the working fluid in the liquid phase;
a vapor pipe configured to flow the working fluid changed to the vapor phase in the evaporator into the condenser; and
a liquid pipe configured to flow the working fluid changed to the liquid phase in the condenser into the evaporator, wherein;
the evaporator includesa housing coupled to the liquid pipe, the housing into which the working fluid in the liquid phase inflows, the housing having a reservoir configured to retain the working fluid in the liquid phase flowed into the housing,a wick disposed in the housing, the wick soaked with the working fluid in the liquid phase, the wick configured to transport the working fluid in the liquid phase,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 coupled to the wick,the groove member is constituted by alternately stacking, along a second direction perpendicular to a first direction from the groove member toward the reservoir,two or more first metal plates coupled to the wick andtwo or more second metal plates disposed at a larger distance from the wick than that of the first metal plate,one vapor flow channel is formed between one of the first metal plates and another of the first metal plates adjacent to the one of the first metal plates at the wick side of the groove member, anda dimension along the first direction is larger than a dimension along the second direction in a cross-sectional surface of each of the vapor flow channels when viewing the groove member along a direction perpendicular to both the first direction and the second direction.

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.
