ABSTRACT:
A cooling arrangement which is primarily intended for incorporation in a high power variable capacitor consists of an elongate deflector mounted within an expandable tubular bellows. The movable end of the bellows carries one of two sets of capacitor vanes, and a fluid coolant is introduced into the other end of the bellows. The fluid is deflected by the deflector into the convolutions of the bellows wall to purge them of air which might otherwise be trapped. In this way the generation of localized hot spots is avoided.
