Abstract

An x-radiator has heat-producing components therein which are enclosed in a housing filled with an insulating fluid surrounding the components. A circulating pump is in fluid communication with the interior of the housing and has respective ports through which the fluid is circulated through the pump between the ports for aiding in dissipating heat from the components. The pump may be integrated within the housing, or attached to an exterior of the housing, with only its ports being in communication with the housing interior. The pump may be a squirrel-cage induction motor with a fluid conveying element, such as a ship's propellor forming a unit with the rotor and being arranged in a protective housing together with the stator.
