Cooling of electrolytic capacitors in electrical climate compressors

A method for producing a connection between at least one cylindrical electrolytic capacitor and a heat sink, wherein the heat sink has at least one bore for at least partially receiving the at least one cylindrical electrolytic capacitor and the at least one bore partially or fully encompasses the at least one cylindrical electrolytic capacitor, and wherein a first section having a constant or variable diameter extends from an outer edge of the at least one bore and terminating inside the at least one bore at a workpiece edge, wherein the first section merges inside the at least one bore into a second section having a constant diameter smaller than the diameter of the first section, the method comprising the steps of:

• a) applying a thermally conductive adhesive in the first section, wherein the applied adhesive protrudes over the workpiece edge into an interior of the at least one bore, and
• b) inserting the at least one electrolytic capacitor at least partially into the second section of the at least one bore before the adhesive is cured, so a portion of the uncured adhesive is pushed into the at least one bore and a lateral surface of the at least one electrolytic capacitor is wetted by the uncured adhesive.
