Blackbody Furnace with Responsive Temperature Controls    

Uses forced convection to improve the efficiency of heat dissipation lowers the temperature of the blackbody furnace quicker.


To lower the temperature quickly the invention dissipates heat using heat convection. An air channel at the underside of the radiation cavity conducts the interior of the radiation cavity with the exterior. This is connected to a high-pressure air source via an airflow controller. To lower the temperature of the blackbody furnace high-pressure air will enter the radiation cavity through the air chamber. The hot air is vented from the opening. The technology improves the efficiency of the heat dissipation by forced convection thereby quickly lowering the temperature of the blackbody furnace. An additional benefit of the invention is it saves power, the blackbody furnace loses less heat in the heating process and the temperature increases faster.

Primary Application of the Technology

Calibration of infrared thermometer and thermal image device.

Patent Summary

U.S. Patent Classes & Classifications Covered in this listing:

Class 219: Electric Heating

This class includes all those devices commonly known as electric heaters, electric-heating metal working apparatus, electrically-heated tools and instruments. This is the generic class for electric heating devices, per se. Devices and systems equipped with electric heating means in which the electric heating means is combined with or includes specific other art structure whereby the heated material is withdrawn, stored or otherwise utilized will also be classified in the appropriate other art class to which it pertains.

Subclass 400: By convection
Subclass 407: Embedded within or between walls of container

Class 373: Industrial Electric Heating Furnaces

Apparatus of this class is characterized by the following: (1) Specialized to the use of electricity as the heat source; (2) heating within a chamber, enclosure, or other holding means; (3) melting of a charge (e.g., materials such as crushed ore or scrap), or preserving a melted charge in a molten state; and (4) manipulated, or operated in an industrial environment.

Subclass 111: Having tubular charge containing or supporting element
Subclass 113: For cooling
