Abstract

A cooling system for an electrical wound electrolyte capacitor wherein the capacitor winding 4 is mounted in a metallic cylindrical-shape housing 5 and the winding 4 has electric foils 7 and 9 which project from both ends with one of the foils being in thermic contact with the floor of the housing 6 and the other foil 9 being in thermal contact with a metallic plate 16. The heat bridges thus formed by faster and greater heat removal for high alternating currents because the temperature within the capacitor is reduced by the two separate bridges.
