Abstract
A blackbody furnace, mainly comprising a radiation cavity, a thermally insulating layer, a heater, a housing, a temperature controller, an airflow controller and a high-pressure air source. Besides, a gas channel is provided at the bottom of the radiation cavity to conduct the interior of the furnace chamber with the exterior. In the process of lowering the temperature of the blackbody furnace, the airflow controller could be actuated by the temperature controller or by an operator. Therefore, the room-temperature high-pressure air will enter the radiation cavity through the gas channel to fast cool down the radiation cavity. Finally, heat air will be vented from an opening at the front end of the radiation cavity. The present invention utilizes forced convection to enhance the efficiency of heat dissipation to fast lower the temperature of the blackbody furnace.
