摘要： A liquid cooling jacket includes a refrigerant flow path which is a flow path having a width in a second direction and in which a heat dissipation assembly is located on a first side in a third direction, where a direction in which a refrigerant flows is defined as a first direction. The refrigerant flow path includes a narrow flow path portion. A width in the third direction of the narrow flow path portion is smaller than a width in the third direction of a flow path on a first side in the first direction with respect to the narrow flow path portion and a width in the third direction of a flow path on a second side in the first direction with respect to the narrow flow path portion.

摘要： The heat exchanger includes a first heat-exchange portion and a second heat-exchange portion. The first heat-exchange portion includes a first header tank having an inflow portion through which the heat medium flows into the first heat-exchange portion. The second heat-exchange portion includes a second header tank having an outflow portion through which the heat medium flows out of the second heat-exchange portion. The first header tank and the second header tank are connected to each other via a connecting portion. The connecting portion has a slit passing through the connecting portion.
