Abstract: A power converter according to the present disclosure includes a cooling plate and a plurality of circuit elements. The cooling plate includes a first cooling surface and a second cooling surface on an opposite side from the first cooling surface. The cooling plate is provided with a through hole passing through between the first and second cooling surfaces. The circuit elements convert AC power supplied from an external power source into DC power of a certain voltage and output the DC power. The circuit elements at least include first and second circuit elements. The first circuit element includes a first terminal and is thermally connected to the first cooling surface. The second circuit element includes a second terminal electrically connected to the first terminal and inserted into the through hole, and is thermally connected to the second cooling surface.

Abstract: An air-conditioning device for a vehicle includes a heat exchanger, a first air flow path, and a second air flow path. The heat exchanger is disposed in an inside space of an intake duct that is provided outside a vehicle interior and that has an opening. The heat exchanger includes a first heat-exchange flow path and a second heat-exchange flow path, and exchanges heat between air flowing in the first heat-exchange flow path and air flowing in the second heat-exchange flow path. The first air flow path introduces, to the first heat-exchange flow path through an opening of the intake duct, air heated by heat generated in an engine, and discharges the air to the outside of the vehicle from the first heat-exchange flow path. The second air flow path introduces, into the vehicle interior through an outside air inlet of the intake duct, outside air introduced into the second heat-exchange flow path.
