ABSTRACT:
A cooling arrangement is provided for capacitor chips (10) or a capacitor assembly (40). A metal foil (18,18',18",18'") is affixed to a chip (10) with electrical insulation therebetween. The foil (18,18',18",18'") has a free end extending beyond the capacitor periphery and transversely of the capacitor stack (13) and can be provided with an L-shaped end (21) or a tube heat exchanger (23) or a fin plate heat exchanger (24). An assembly (40) of capacitors (30 to 38) can be arranged between legs of U-shaped metal heat exchange members (25,26,27) which conduct heat from the capacitors (30 to 38) through the legs and to a coolplate (28) having a tube (29) for passage of coolant.
