Abstract: A convector includes a rotor having a shaft extending along an axis of rotation, and a plurality of discs offset from one another along the axis of rotation and mechanically coupled to and rotatable with the shaft. The convector also includes a stator having a plurality of plates offset from one another along the axis of the shaft. Each plate of the plurality of plates defines a through-hole configured to receive the shaft and an opening configured to receive a corresponding disc of the plurality of discs. Rotation of the shaft causes each disc to rotate at least partially within the opening defined by the corresponding plate, and relative to the corresponding plate.

Abstract: A convector for cooling a microprocessor includes a volute-shaped housing, a stator, and a rotor, and can be mounted to a CPU board of a computing device for thermal coupling with the microprocessor. The volute-shaped housing of the convector encapsulates the stator and the rotor, and has a radially outer casing which defines a single exit port for guiding a fluid out of the housing. The stator has a plurality of plates configured to conduct heat. The rotor has a plurality of disks and a shaft extending longitudinally along the housing. Together, the housing, the stator, and the rotor define a spiral flow path through the volute-shaped housing, in both radially outward and longitudinal directions, to the single exit port. A motor may be provided to impart rotational motion to the rotor.

Abstract: A convector includes a stator made up of an array of fixed, parallel, equally spaced, equally thick, thermally conductive plates attached to a relatively thick thermally conductive plate. Convectors are provided with a rotor that is made up of an array of flat, rotatable, parallel, equally spaced, equally thick discs. The discs of the rotor are placed between the plates of the stator at relatively close proximity from the walls of the stator plates. Furthermore, the discs are keyed or held in place with the help of spacers and compression nuts to a hollow or a solid shaft. A clearance aperture, circular in shape, is provided on the stator plates. The shaft is held in place at both ends by roller bearings that provide the means for the shaft to rotate. To impart rotational motion to the rotor, the shaft is attached to an external device such as a motor.
