  • Patent number: 5117901
    Abstract: A two-phase capillary pumped loop heat transfer system adapted primarily for use on space vehicles, includes a wickless condenser tube which receives gaseous phase working fluid from the evaporator capillaries, rejects heat from the working fluid to a heat sink (e.g. outer space) and thereby converts the gaseous phase working fluid to its liquid phase, and returns the liquid phase working fluid to the evaporator to complete the thermal cycle. A portion of the condenser tube is supported by a rigid radiator structure external to the spacecraft. At least a portion of the condenser tube is deformable to permit the radiator structure to be deployed from a first predetermined position to a second predetermined position with respect to the spacecraft. The deformable segment of the condenser tube can be formed into a helical coil used as a spring to assist deployment of the radiator panel.

The static pressure caused by the presence of the apparatus in the duct is then substantially reduced when in this second position and results in reduced power consumption of a fan used to generate the air flow. The fan is automatically controlled by a volume controller with a probe which senses changes in static pressure and air flow rate in the duct. The volume controller adjusts the fan motor speed and inlet guide vanes to save more than 25% of the energy used to operate the fan over a whole year.

  • Patent number: 4733720
    Abstract: In a water cooling arrangement for insertable component parts groups in devices of power electronics, the carrier element on which the component parts are arranged is fashioned as a component parts carrier independent of the cooling member. A water-traversed cooling member which is seated essentially apparatus-rigid can be individually brought into thermal interaction with every component parts carrier inserted into the device in the composite of an insert being brought into thermal interaction therewith by the force of resilient elements at heat transmission surfaces precisely mating to one another which are fashioned at component parts carriers and cooling members. With a mechanical device all cooling members can be distanced in common from the apertaining component parts carriers opposite the acting direction of the forces of the resilient elements. A replacement of component parts carriers is thereby enabled without performing manipulations at devices of the cooling water circulation.

  • Patent number: 4709559
    Abstract: A cooling system for relatively movable components, such as a rotor seated for rotation with respect to a stationary component, includes a sealed channel in the stationary component disposed between the stationary component and the movable component, and an evaporator disposed within the sealed channel. The channel is filled with coolant, such as alcohol or oil, which is circulated by a pump in a closed circulation path. Heat is thereby conveyed from the system components to be cooled to the evaporator, and from the evaporator to a location where the heat can be dissipated without disturbing operation of the device. The cooling system is suitable for use, for example, in a computer tomograph for cooling the radiation detector.

  • Patent number: 4640344
    Abstract: A rotary, Perkins tube heat exchanger for processing hot contaminated gas flows emanating from appliances such as laundry driers, grain driers and the like. The case of the heat exchanger is located relative to the rotor so as to lie in the gas flow boundary layer established by the latter. The case is provided with a boundary layer purge port in the hot gas chamber. An airfoil extends inwardly from the case into the gas flow boundary layer. It causes increased local turbulance in the boundary layer gas. It also diverts a predetermined proportion of the boundary layer gas and its burden of contamination products out through the purge port. The boundary layer airflow cleans both the interior of the case and the rotor, even through the rotor is characterized by the presence of a multiplicity of small openings. The device thus is rendered self-cleaning and may be operated for extended periods of time without buildup of contaminants within the heat exchanger case.
