Capacitor module
First Claim
1. A capacitor module comprising:
- a plurality of capacitors each including a capacitor case which houses a capacitor element, the capacitor case having an outer bottom wall part thicker than other walls and a screw hole formed in the outer bottom wall part; and
a heat dissipater to which each of the capacitors is fixated with a fixation screw screwed into the screw hole, whereinthe heat dissipater is made of metallic material, anda sheet member, which is made of electrically insulating and thermally conductive material, is interposed between an outer wall surface of the capacitor and the heat dissipater,an interposed member made of electrically insulating material is interposed between the fixation screw and the heat dissipater.

Abstract
The capacitor module includes a capacitor, in which a screw hole is arranged on an outer bottom wall surface of a capacitor case housing a capacitor element, and a heat dissipater, on which a plurality of capacitor cases are fixated by screwing fixation screws in the screw holes of the capacitors. As a result, for example, the capacitor can be fixated with reliability and durability secured even under a condition where very strong vibration is continuously applied, for example, when the capacitor module is mounted on construction machinery. Further, because, an adherence of the outer bottom wall surface of the capacitor case on a fixation surface of the heat dissipater is strengthened by screwing the fixation screw in the screw hole, the capacitor can be cooled down by transferring heat produced by the capacitor to the heat dissipater as needed.
