A power converter comprising: a power conversion circuit to convert an input power into a direct current power or an alternating current power; a base member made of resin on which the power conversion circuit is mounted; a cover member, wherein the power conversion circuit is housed between the cover member and the base member; a coolant flow path provided in an interior of the base member, through which a coolant for cooling the power conversion circuit is circulated; and a temperature sensor provided on the base member, to sense the temperature of the coolant circulating through the coolant flow path, wherein the temperature sensor has a conductive member including at least a thermistor, and at least a part of the conductive member is surrounded by a resin wall formed of an insulating material.

Power converter

Provided is an electric power converter that includes an inverter which includes plural electric parts, a smoothing capacitor configured to smooth electric power, a housing configured to house the inverter and the smoothing capacitor and a first conductor portion configured to connect the smoothing capacitor and the inverter. The housing includes a base portion made of a resin material and a cover portion attached to the base portion to cover the inverter and the smoothing capacitor. The inverter and the smoothing capacitor are mounted on the base portion. The first conductor portion is placed in the vicinity of or in contact with the base portion of the housing in the middle of connection between the smoothing capacitor and the inverter.

Electric power converter

An electronic component housing that internally houses an electronic component includes a portion formed of a resin material and a portion formed of a metallic material. The portion formed of the resin material is a connection side portion opposed to a member as a connection partner of the electronic component housing, or an opposite portion opposed to the connection side portion. The electronic component housing further includes an electromagnetic shield member that covers an outer surface of the portion formed of the resin material.

Electronic component housing

An elastic seal member is formed at the surface of a metal plate included in a gasket, which faces toward a lid, and another elastic seal member is formed at the surface of the metal plate facing toward a side wall. At the metal plate, the seal member is disposed further inward relative to the other seal member fitted in a seal groove. As bolts are tightened, the seal members become compressed and deformed, causing the seal member to press the metal plate against an exposed portion of an inner wall portion and the other seal member to press the metal plate against the lid.
