ABSTRACT:
A heat generating device includes a sealed metal drum with spaced peripheral fins and houses a cage-like agitator mounted on a rotatable shaft axially disposed therein and extending through one end for connection to a source of power. The agitator includes a plurality of elongated flat bar-like vanes arranged in close concentric relationship to the drum and supported by spaced apertured hubs on the shaft. The periphery of each hub has serrated type notches so that the vanes are tangential to the hubs and in off-set alignment with each other. Relative to the direction of rotation of the agitator, the leading edge of each vane is spaced inwardly from the trailing edge of the adjacent vane a predetermined distance to provide a restricted passageway. A supply of oil within the drum is forcibly driven by rotation of the agitator through the restricted passageways to the inner wall of the drum and upwardly thereon to return to the interior of the agitator through the hubs for repeated circulation through the passageways. The oil is heated by the shearing force of movement between the vanes to heat the drum and fins and means are provided to distribute heat radiating from the drum and fins to any desired point of use. An expansion and accumulator chamber communicating with the interior of the drum is provided for heated air.
