Abstract: An apparatus for cooling an electrical heat source is disclosed. A heat exchanger has two principal sub-assemblies. A closed-loop fluid flow is provided through a second sub-assembly, disposed next to a heat source. An open-loop fluid flow is provided though a first sub-assembly in communication with a second sub-assembly. Each of the first and second sub-assemblies has a rotational element. The fluid flow entering the first sub-assembly rotates the first rotational element, and magnetic communication between the rotational elements causes movement of the second rotational element, thereby achieving fluid movement within the second sub-assembly. Operationally, the closed-loop sub-assembly removes heat from the heat source and transfers it to the open-loop sub-assembly for subsequent heat transfer in a downstream fluid flow.

Abstract: A header for a heat exchanger orients the position of an inlet port at an angle offset from the position of the outlet port on the header body in order to simplify the plumbing of the header within a system. In one implementation of a header for a heat exchanger, the header forms a header cavity defined by an external wall and which is separated into an inlet chamber and an outlet chamber by a dividing wall. An inlet port is defined within the external wall and is in fluid communication with the inlet chamber. Similarly, an outlet port is defined within the external wall and is in fluid communication with the outlet chamber. The inlet port is oriented on the external wall at an offset angle with respect to a position of the outlet port.

Abstract: A vehicle air circulating system comprises a controller, an interior condition sensor attached to the controller, an instrument panel, and a deployable register assembly attached to the controller and pivotably attached to the instrument panel. The register assembly includes a first register and a second register and is movable between a closed position in which the first register is recessed within the instrument panel and is thus obstructed and an open position in which the first register is deployed. The second register remains unobstructed whether the register assembly is in its closed or open position. The deployable registers provide directional control for pull down conditions. Once the desired conditions are achieved, the deployable registers lower into the instrument panel and the other registers provide a larger opening to direct the air overhead at lower velocities keeping the vehicle cabin cool while not blowing in the direction of the occupants.

Abstract: A vehicle climate control system. An air conditioner and heater are operatively connected to a controller and control the temperature of the cabin area of a vehicle. A processor, operatively connected to the controller, determines the amount of time for an operator of the vehicle to travel between their location and the location of the vehicle. The processor determines an amount of time required to adjust the temperature of the cabin area of the vehicle to a selected temperature by using one of the air conditioner and the heater. The processor automatically operates one of the air conditioner and the heater to begin adjusting the temperature of the cabin area to the selected temperature when the amount of time required for the operator to travel between their location and the location of the vehicle is less than or equal to the amount of time required to adjust the temperature of the cabin area vehicle to the selected temperature.

Abstract: The dehumidifier uses an all-plastic air-to-air heat exchanger together with an integral chiller to cool the incoming air to remove water vapor, and then exchange heat with incoming air to cool the incoming air and re-heat the outgoing air.
