摘要： In a power conversion apparatus, electronic components and a cooler are integrated in a frame as an internal unit. The internal unit is fixed within a case through the frame. The frame has such a shape that the electronic components are surrounded by the frame, and includes a first wall section, and second and third wall sections extending from both sides of the first wall section. The cooler includes a coolant introduction tube and a coolant discharge tube. The coolant introduction tube and the coolant discharge tube project outward from to the frame. The first to third wall sections include a support wall section supporting at least one of the coolant introduction tube and the coolant discharge tube, and a frame wall section not supporting the coolant introduction tube and the coolant discharge tube. The thickness of the support wall section is larger than the thickness of the frame wall section.

摘要： The power conversion apparatus includes electronic components constituting a power conversion circuit, a cooler for cooling at least some of the electronic components, and a case housing the electronic components and the cooler. The at least some of the electronic components and the cooler are fixed to and integrated in a frame as an internal unit . The internal unit including therein the semiconductor modules also includes a control circuit board fitted to board fixing sections formed in the frame so as to project from the frame in the height direction perpendicular to the plane of the frame. Each of the board fixing sections has a board abutment surface at a position closer to the frame than the tips of control terminals of the semiconductor modules formed so as to project in the height direction.

摘要： A reactor is provided with a coil, a core, and a case. The coil generates magnetic flux in response to supply of current thereto. The core is made of magnetic powder-containing resin filled in spaces inside and outside of the core. The case accommodates therein the coil and the core. The reactor is also provided with a cooling pipe (cooling member), which is arranged to be in contact with the core. A power converter is provided with semiconductor modules, a cooler, and the reactor. In the power converter, the cooler is arranged partially being in contact with the core of the reactor.
