Title:
MOUNTING STRUCTURE FOR ELECTROLYTIC CAPACITOR
Document Type and Number:
Japanese Patent JP2023137683
Kind Code:
A
Abstract:
To provide a mounting structure for an electrolytic capacitor capable of improving a heat dissipation property of the electrolytic capacitor while suppressing contact between an explosion-proof valve and a metal housing.SOLUTION: A mounting structure 100 for an electrolytic capacitor 53 comprises the electrolytic capacitor 53, a substrate 51, a metal housing 20, and a heat transfer member 70. The heat transfer member 70 is formed from a silicon-based soft material having a predetermined hardness. A main body part 54 of the electrolytic capacitor 53 is fitted into a recess 22 while keeping gaps G1 and G2 in such a manner that a location exists where an interval L1 with another side face 54b of the main body part 54 with respect to the recess 22 of the metal housing 20 is larger than an interval with a circumferential surface 54c of the main body part 54. The heat transfer member 70 fills the gals G1 and G2 so as to cover the main body part 54 inside of the recess 22. The heat transfer member 70 is allowed to be deformed to limit outflow of an electrolyte 53b from the recess 22 when actuating an explosion-proof valve 56.SELECTED DRAWING: Figure 5
