Patent ID: 8493731

Claim:
A forced-air-cooled type vehicle control device having an air blower that sends cooling air to an exothermic part and is installed under a vehicular floor of an electric vehicle, wherein the forced-air-cooled type vehicle control device comprising: a control circuit component including a contactor; a snubber circuit component that is a voltage-absorbing circuit component; a capacitor that is electrically connected to a converter and an inverter and smoothes an output of the converter; a semiconductor device provided in the converter and the inverter; a cooler that cools heat generated by the semiconductor device and the snubber circuit component utilizing cooling air from the air blower; a conductor bar that electrically connects the semiconductor device to the capacitor; and a bus bar that electrically connects the conductor bar and the capacitor, the forced-air-cooled type vehicle control device further comprising: a first accommodating chamber that accommodates a first support body that supports a cooling unit of the cooler such that the first support body can move in a side surface direction of an electric vehicle; and a second accommodating chamber that is arranged below the first accommodating chamber and accommodates a second support body supporting the capacitor such that the second support body can move in the side surface direction of the electric vehicle, the cooling unit including the semiconductor device, the snubber circuit component, the cooler, and the conductor bar, wherein the bus bar is formed into a flat-plate shape, and the conductor bar and the capacitor are connected to a same surface of the bus bar through screws inserted through screw holes formed in the bus bar, and the conductor bar and the capacitor can be separated from each other by detaching one of a connecting portion between the bus bar and the conductor bar and a connecting portion between the bus bar and the capacitor.
