20110194246 | POWER CONVERSION APPARATUS - An electric power conversion apparatus is provided which includes electronic components, a cooler, an internal unit, a capacitor, and a case. The internal unit has a frame to which at least one of the electronic components and the cooler are secured and which surrounds all around the one of the electronic components. The frame includes unit fixing sections through which the internal unit is fixed to the case and capacitor fixing sections through which the capacitor is fixed to the internal unit. The capacitor fixing sections are located inward of the frame more than the unit fixing sections. The internal unit is fixed to the case and thus works as a beam to increase the mechanical rigidity of the case. The fixing of the internal unit to the case minimizes external force to be exerted through the case on the electronic component and the cooler. | 08-11-2011 |
