ABSTRACT:
The invention relates to a method for cooling an electrolytic capacitor comprising a casing (1) that surrounds a capacitive element (2), and to an electrolytic capacitor. The casing (1) is provided with a hollow (3), and a cooling element (4) made of an electrically insulating material is placed in the hollow (3), the cooling element comprising at least one duct (5), which can be arranged to receive a cooling medium. Since the cooling element placed in the hollow is made of an electrically insulating material, the cooling medium can be liquid, such as water.
