ABSTRACT:
A heat circulation device is provided which is portable to be usable placed upon conventional space heaters and particularly upon kerosene fueled heaters which includes a plenum housing adapted to be placed upon the heater which defines a plenum chamber therein for gathering heated air. The upper surface of the plenum chamber defines a generally convex heated surface and the sidewalls of the plenum chamber include apertures therein. A main housing is located immediately above the plenum housing which is adapted to provide a flow of cool air via a blower assembly wherein this cool air is guided to travel across the convection surface to be warmed thereby and then to travel past the hot air apertures to create a suction thereagainst similar to the Venturi principle and hence draw warm air outward therefrom. In this manner the heated air being supplied into the plenum chamber from the kerosene or other heater will be re-circulated in an outwardly directed manner 360.degree. with respect to the heat circulation device itself. The convection surface is convexed and inclined slightly downwardly in all directions to thereby urge this warm air into the lower areas of the surrounding room to facilitate circulation thereof.
