1. A device for thermally conditioning and moving a fluid to a climate controlled seat assembly, comprising:

  • a thermoelectric device to convert electrical energy into thermal energy producing a temperature change in response to an electrical current being applied thereto;

    a fluid transfer device to produce a fluid flow that is in thermal communication with the thermoelectric device so that the thermal energy generated by the thermoelectric device is transferred to or from the fluid flow;

    a protective casing configured to be positioned within or adjacent the climate controlled seat assembly, the protective casing defining an interior space and having an outlet and an inlet through which the fluid flow is directed, the thermoelectric device and the fluid transfer device being positioned within the interior space of the protective casing;

    a sensor configured to provide a temperature signal that is indicative of a temperature of the fluid flow;

    a control unit positioned within the protective casing and operatively connected to the sensor, the control unit configured to receive a set point signal that is indicative of a desired temperature of the fluid flow, and based upon the set point signal and the temperature signal, to control the thermoelectric device and the fluid transfer device; and

    electrical wires connected to the control unit and extending through an opening in the protective casing.
