Heat collector and diffuser

Claim 2

A heat collector and diffuser apparatus for installation over an existing room heating system employing elongated fin tube radiators for controlling the distribution of heat therefrom and for providing a more uniform environmental heating of the room or space, said apparatus comprising: housing means adapted to be placed over said elongated radiator in nested relationship thereto, said housing means having an outlet means for exhausting air to the room at the upper end of said housing means, said housing means enclosing the upper portion of said radiator and excluding outside air, blower means associated with said housing means for inducing air flow across said fin tube radiator and through said housing for exhausting said air flow through said outlet means, thermostat means for controlling said blower means in accordance with a desired room temperature, and elongated collector ducts on said housing means for nesting superimposition over and for resting on an elongated fin tube heat exchanger for collecting air flowing across said fin tube radiator and an inlet means associated with said collector ducts for disposition substantially across the fin tube radiator to collect hot air thereacross as induced by said blower means to flow into and through said collector ducts to said blower means.

Claim 3

The apparatus of claim 1 in which said blower means is located within said housing means and comprises fan means and electric motor means for driving said fan means, said fan means adapted to discharge said air flow through said outlet means and to induce said air flow across said fin tube radiator and through said inlet means.

Claim 4

The apparatus of claim 1 in which said thermostat means includes a room air temperature switch having a selective presetting for energizing said blower means if the room air temperature falls below said presetting on said room air temperature switch.

Claim 5

The apparatus of claim 3 in which said thermostat means includes a control means for controlling the speed of said fan means so as to vary the quantity of said air flow proportionately with the difference between the room air temperature and said presetting on said room air temperature switch.

Claim 6

A heat collector and diffuser apparatus for use with room heating systems employing elongated fin tube radiators for controlling the distribution of heat therefrom and providing a more uniform heating of the room or space, said apparatus comprising: housing means having lower inlet means and upper outlet means, said housing means including a central upright blower section with a top and a bottom, said upper outlet means provided in said top and a bottom opening provided in said bottom. a tapered outrigger collector duct depending from said bottom of said upright section and extending beyond each side thereof for overlying substantially the length of said fin tube radiator, electric blower means disposed within said upright section, said blower means directed to discharge air through said outlet means and adapted to suction air into said bottom opening, thermostat means co-operative with said electric blower means for selective energization thereof, said outrigger collector ducts co-operative with said bottom opening of said upright blower section for channeling air therethrough, and walls on said outrigger ducts defining an elongated opening in the bottom thereof to receive in nesting relationship substantially the entire length of said fin tube radiator for drawing air across said radiator and for channeling said air into said central upright blower section for forced exhaust by said electric blower means through said outlet means and into the room or space.

Claim 7

A heat collector and diffuser apparatus for use with room heating systems employing elongated fin tube radiators for controlling the distribution of heat therefrom and providing a more uniform heating of the room or space, said apparatus comprising: housing means having lower inlet means and upper outlet means, said housing means including a central upright blower section with a top and a bottom, said upper outlet means provided in said top and a bottom opening provided in said bottom. a tapered outrigger collector duct depending from said bottom of said upright section and extending beyond each side thereof for overlying substantially the length of said fin tube radiator, electric blower means disposed within said upright section, said blower means directed to discharge air through said outlet means and adapted to suction air into said bottom opening, thermostat means co-operative with said electric blower means for selective energization thereof, said outrigger collector ducts co-operative with said bottom opening of said upright blower section for channeling air therethrough, and walls on said outrigger ducts defining an elongated opening in the bottom thereof to receive in nesting relationship substantially the entire length of said fin tube radiator for drawing air across said radiator and for channeling said air into said central upright blower section for forced exhaust by said electric blower means through said outlet means and into the room or space.

Claim 8

The apparatus of claim 5 in which said collector duct includes portions thereon adapted for seated engagement upon said fin tube radiator.

Claim 9

The apparatus of claim 5 in which said collector duct has a front lip portion which overhands said radiator.
