Provided is an electrical component housing for housing an electrical component. The electrical component housing includes a resin base portion allowing the electrical component to be mounted, a metal cover portion attached to the base portion and configured to cover the electrical component, a metal plate in contact with a bottom surface of the base portion in a manner of covering the bottom surface of the base portion. The electrical component housing also includes a conductive member provided in a through hole that penetrates the base portion in a thickness direction of the base portion, wherein the conductive member electrically connects a ground terminal of the electrical component and the metal plate.

Electrical component housing

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

A power converter () includes a power converter circuit (), a cooler (), and a cover member (). The power converter circuit is configured to convert input electric power into DC power or AC power. The power converter circuit is placed on the cooler. The cooler is configured to cool the power converter. The power converter circuit is housed between the cooler and the cover member. The cooler () includes a main body (), a coolant flow passage (), and a coolant input/output portion (). The coolant flow passage is formed inside the main body. A coolant is circulatable through the coolant flow passage. The coolant input/output portion is coupled to the coolant flow passage. The coolant input/output portion includes a coolant introduction pipe () and a coolant discharge pipe (). The coolant introduction pipe introduces the coolant from outside the cooler. The coolant discharge pipe discharges the coolant to outside the cooler. The coolant input/output portion () is joined to the main body. The joined part () has a joining strength lower than a strength of the main body.
