  • TWO-STAGE HYDRODYNAMIC PUMP AND METHOD
    Publication number: 20080273990
    Abstract: A two-stage pump having an internal fluid pathway or cycle for providing cooling to various parts in the pump, such as, an electric motor in the pump, and also for lubricating at least one or a plurality of bearings in the pump. The pump utilized hydrodynamic bearings that are adapted or configured to provide various passageways, channels and the like for using the fluid that is being pumped by the pump as lubrication for at least one or a plurality of bearings in the pump.

  • Method and system for cooling heat-generating component in a closed-loop system
    Patent number: 7093977
    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.

  • System and method for cooling an x-ray tube in a tomography computer system
    Patent number: 6997609
    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.
