Abstract: A system and method for improving cooling of a heat-generating component in a closed-loop cooling system is shown. The system comprises a venturi having a throat which is coupled to an expansion tank that may be exposed to atmospheric pressure in the embodiment being described. A closed expansion tank may be provided in the system to force or continue to cause fluid flow to cool the heat-generating component after a pump stops.

Abstract: A system and method for cooling an X-ray tube in a computer tomography (CT) cooling system is shown having a heat exchanger that has at least one cooling passageway for receiving a coolant for cooling the X-ray tube and that is formed to define a tubular passageway having or defining a heat exchanger axis. The tubular passageway has a first open area and a second open area, and, in one embodiment a first axial fan and a second axial fan, respectively, are situated adjacent to the first and second open areas. The heat exchanger is mounted on a gantry of the computerized tomography system such that the axis of the axial fans and the heat exchanger axis are generally parallel to the gantry axis so as to reduce or minimize the effects of gyroscopic forces.

Abstract: A system and method for improving cooling of a heat-generating component in a closed-loop cooling system is shown. The system comprises a venturi having a throat which is coupled to an expansion tank that is exposed to atmospheric pressure in the embodiment being described. The venturi, when used with a pressure switch, can operate to determine a flow rate which can be used to generate a signal which in turn is used to activate or deactivate one or more of the components, such as the heat-generating component, in the system. Also shown is another embodiment wherein a circular venturi is provided to permit a venturi passageway to be defined about an axis of the pump in order to shorten the overall length of the pump and venturi combination.

Advantageously, the design of the embodiment described has a convenient system which utilizes a pressure switch, thereby eliminating the need for a differential pressure switch of the type used in the past.
