Provided is a cold plate that can improve cooling efficiency and simultaneously suppress an increase in size in the thickness direction. A heat-transfer-medium flow spaceis formed between a heat dissipation surface of a base plate and a cover plate, the base plate has a plurality of heat transfer portionsthat are provided so as protrude from the heat dissipation surface toward the cover plateand that transfer, to a heat-transfer medium flowing through the heat-transfer-medium flow space, heat released from the heat dissipation surface, and concave portions, into which at least a portion of tips of the plurality of heat transfer portionsare inserted, are formed in a surface of the cover plate facing the heat-transfer-medium flow space.

Cold plate and method of manufacturing cold plate

Provided is a heat pipe which is installed in a cold region in a bottom heat posture in which a longitudinal direction of a container is substantially in parallel with a gravitational direction, is capable of preventing the container from deforming even when a working fluid has become frozen, and has excellent heat transport properties.

Heat pipe

Heatsink

Heat sink

The present disclosure provides a heat pipe capable of preventing deformation of even a thin container and having excellent heat transfer characteristics by preventing freezing of a working fluid even if the longitudinal direction of the container is set substantially parallel to the direction of gravity in cold regions. A heat pipe includes a container having a tubular shape with both ends sealed, a wick structure stored in the container, and a working fluid sealed in the container, wherein, in at least one of cross sections perpendicular to the longitudinal direction of the container, the wick structure is in contact with the inner surface of the container at two points but both side surfaces of the wick structure are not in contact with any inner surface of the container, and a sintered metal layer is formed on the container inner surface being not in contact with the wick structure.
