Abstract
A high-efficiency light type high-temperature black-body furnace comprises a controller. The controller controls a vacuum-pumping device to vacuumize a laminated type blackbody chamber. A temperature detecting device is arranged inside the laminated type blackbody chamber. The temperature detecting device is connected with a temperature control device. The temperature control device is connected with the controller. The controller controls a frequency conversion induction power supply to supply power to the laminated type blackbody chamber. The controller further controls a protecting device outside the laminated type blackbody chamber. Salt bath furnace transformer transformation heating methods of a conventional high-temperature black-body furnace are replaced by frequency conversion induction heating and intelligentized frequency conversion induction heating methods. The frequency conversion induction power supply and the laminated type blackbody chamber are further effectively combined to reduce the power consumption of the high-temperature black-body furnace. Meanwhile, a vacuum-pumping means is adopted to replace conventional inert gas to protect the chamber. Therefore, the power consumption and the volume of the high-temperature black-body furnace are only one eighth to one fifth those of the conventional black-body furnace of the same class. The high-temperature black-body furnace has the advantages of accelerated temperature rise, low power consumption, small volume, lightness and high identifying and measuring efficiency.
