<p>A capacitor module having increased strength as a whole and having increased freedom in design of a cooling medium flow passage to be formed in the module. The capacitor module is provided with capacitor cells each having a capacitor and a capacitor case which is equipped with first closed-bottomed screw holes having respective openings in the bottom surface of the capacitor case and which houses the capacitor, a metallic cell-fixing body having through-holes communicating with the first screw holes and to which the capacitor cells are fixed by engaging cell screws into the through-holes and the first screw holes, an insulator consisting of a thermally conductive insulating material, installed between the cell-fixing body and the capacitor cells and, and insulating between the cell-fixing body and the capacitor cells, and a metallic heat-dissipating body having second closed-bottomed screw holes into which screws for the cell-fixing body are engaged and also having a flow passage for causing the cooling medium to flow to the rear side of that surface of the heat-dissipating body in which the second screw holes are formed.</p> |
