摘要: A cooling structure for an inverter (31) controls a motor (6) to drive an automobile. This inverter device (22) includes a power circuit section (28) having an inverter (31) to convert a DC power of a battery (19) to an AC power for the motor (6), and a casing (39) enclosing the power circuit section (28). A fin (41) is provided in an outer surface of the casing (39), a coolant path (42) for the flow of a cooling medium is provided within the casing (39) or in the outer surface thereof, and a pump (43) circulating the cooling medium in the coolant path (42) is disposed on or in the casing (39). With this structure, the flow resistance for cooling the inverter (31) is reduced to allow the pump (43) to be downsized and a proper cooling can be accomplished to the amount of heat by the inverter (31).
