1. A cold plate comprising:
a main body in contact with a heat source, wherein
the main body:
has:
an inflow hole through which a refrigerant flows in;
an outflow hole through which the refrigerant flows out; and
an internal space communicating with the inflow hole and the outflow hole and through which the refrigerant flows; and
comprises:
a first heat exchange layer in the internal space; and
a second heat exchange layer in the internal space,
the first heat exchange layer and the second heat exchange layer are laminated in a thickness direction of the first heat exchange layer and of the second heat exchange layer,
the first heat exchange layer has:
a first flow path through which the refrigerant flows in a first direction; and
a second flow path through which the refrigerant flows in the first direction and disposed at a position different from the first flow path in a second direction intersecting the first direction, and
the second heat exchange layer has:
a cross flow path in the internal space that communicates with the first flow path and the second flow path such that the refrigerant flows therethrough in the second direction.
