摘要： A cooling device includes (i) a heat receiving block that is a plate-like member to which an exothermic element is attached, and (ii) a cooling member that radiates, to surrounding cooling air, heat transmitted from the exothermic element via the heat receiving block. The cooling device includes (i) at least one header that extends in a Y-axis direction that is a direction in which the cooling air flows, the header being attached to a second main surface, and (ii) branch pipes that are attached to each of the at least one header, the branch pipes extending in a direction away from the second main surface. The branch pipes communicate with the header. A shape of each of the branch pipes in a Y-Z plane is a flat shape, and a longitudinal direction of the flat shape is parallel to the Y-axis direction.

摘要： A cooler configured to cool an electronic device includes: a refrigerant inlet portion configured to guide refrigerant from an outside of a casing to an inside of the casing; a refrigerant outlet portion configured to guide the refrigerant from the inside of the casing to the outside of the casing; and a metal member configured to define a flow path region in which the refrigerant is caused to flow from the refrigerant inlet portion to the refrigerant outlet portion in the inside of the casing. The metal member includes: a plurality of opening portions configured to cause the refrigerant to pass therethrough; and a capture and reduction portion having such a shape as to capture air bubbles, which are generated through a connection surface between the casing and the electronic device, so as to reduce the air bubbles through cooling by the refrigerant when the electronic device is cooled.

摘要： A plate heat exchanger causes heat exchange to be performed using a plurality of heat transfer plates stacked. Each of the heat transfer plates includes a plate body, a first-medium inlet, a first-medium outlet, a second-medium inlet, a second-medium outlet, and a projection that provides a passage. At least one of the first-medium inlet and the first-medium outlet is located at one of two corners at one end of the plate body which the projection contacts. At least one of the second-medium inlet and the second-medium outlet is located at one of two corners at the other end of the plate body from which the projection is separated.

摘要： A heat pump apparatus includes a use-side heat exchanger that cause heat exchange to be performed between a heat medium flowing from a heat-storage heat exchanger and a heat usage medium, and a flow-passage switching device that switches a flow passage for the heat medium to a first flow passage that circulates through a heat-reception-side heat exchanger and the heat-storage heat exchanger without extends through the use-side heat exchanger or a second flow passage that circulates through the heat-reception-side heat exchanger and the heat-storage heat exchanger via the use-side heat exchanger. Even when the temperature of the heat storage medium rises, heat received from a heat source can be stored in the heat storage medium by a heat pump, while a decrease of the efficiency of the heat pump can be reduced.
