摘要： A cooling device for a semiconductor element module and a magnetic part, includes: a water-cooled type heat sink having a cooling water passage; a semiconductor element module including a plurality of chips arranged side by side in a circulation direction in the cooling water passage, the semiconductor element module being mounted on the heat sink; and a magnetic part including a core and a winding portion mounted on the core, the magnetic part being mounted on the heat sink or another heat sink. In the cooling device, a plurality of cooling fins is disposed to extend along the circulation direction in the cooling water passage in a manner that the plurality of cooling fins are separated into groups for the respective chips arranged side by side in the circulation direction, and that the groups of the cooling fins are offset from each other in a direction perpendicular to the circulation direction. Accordingly, it is possible to have improved cooling efficiency of a heat sink with cooling fins.

摘要： In a power conversion device including: a converter which steps up or down a voltage of a direct current power supply; and an inverter which converts the direct current voltage obtained by the converter into an alternating voltage to drive an electric motor, a plurality of magnetic parts are arranged above a switching element assembly unit with a water-cooled type second heat sink interposed between the switching element assembly unit and the plurality of magnetic parts, the switching element assembly unit configured by mounting all the switching element modules on upper and lower surfaces of a water-cooled type first heat sink. Accordingly, it is possible to provide a power conversion device capable of housing many switching element modules in a compact space and cooling them effectively, while preventing the influence of a noise due to the magnetic parts from acting on the switching element modules as much as possible.

摘要： A brake structure for a wheel rotating device includes a motor provided in a wheel and is driven for rotating the wheel, and a braking mechanism for actuating brake to brake the wheel. The motor includes: a motor housing; a stator positioned in and fixed to the motor housing; and a rotor positioned in the motor housing and facing to the stator. The braking mechanism includes: a brake rotor to rotate with the wheel; frictional members to be in contact with the brake rotor for generation of braking force; a pressing force generating unit for generating pressing force of the frictional members so that the frictional members are urged to and pressed against the brake rotor by supplying brake fluid through a brake fluid passage to transmit fluid pressure; and a housing for the pressing force generating unit. The brake fluid passage is formed inside a wall of the motor housing, and is connected to a brake fluid supply port provided in the housing for the pressing force generating unit.
