An electronic device with a cooling function includes a cap nut, a case, a semiconductor unit, a second bus bar for external output, and a connecting bolt. The case includes a side wall and a bottom surface. The bottom surface of the case has a coolant passage and a recessed portion to receive the cap nut. The coolant passage is open to above and is generally U-shaped. The recessed portion is positioned in a position surrounded by the coolant passage and the side wall of the case, and the cap nut is received in the recessed portion. The semiconductor unit includes a first bus bar that extends from the semiconductor unit. The semiconductor unit is fixed to the case in a posture and position that closes off the coolant passage from above. The second bus bar passes through the side wall of the case. Inside the case, the connecting bolt passes through the first bus bar and the second bus bar and screws into the cap nut, and the cap nut and a head portion of the connecting bolt bring the first bus bar and the second bus bar into close contact.

Electronic device with cooling function

A drive device for a vehicle includes a motor generator generating drive force, and a power control unit provided integrally with the motor generator for controlling the motor generator. The includes a low-voltage circuit section to which a relatively low voltage is applied, a high-voltage circuit section which is located at a rear side of the vehicle relative to the low-voltage circuit section and to which a relatively high voltage is applied, and a cooling plate located between the low-voltage circuit section and the high-voltage circuit section in a longitudinal direction of the vehicle for cooling the high-voltage circuit section. With such configuration, the drive device for a vehicle allows the power control unit to be protected appropriately against an externally imposed shock.
