STRUCTURAL DESIGN AND PROCESS TO IMPROVE THE TEMPERATURE MODULATION AND POWER CONSUMPTION OF AN IR EMITTER

摘要

An infrared emitter is formed having a reduced thermal mass and increased thermal conductivity to effectively deliver and dissipate heat from a heating element that emits electromagnetic radiation. The improved thermal dynamic process may enhance one or both of power consumption and/or longevity.

主权项

1. An infrared emitter, the emitter comprising:
a substrate having a first surface and a second surface opposite the first surface, the substrate being substantially planar; a heating element disposed on a portion of the first surface of the substrate, the heating element being configured to emit infrared electromagnetic radiation in response to an electrical current being introduced thereto; and a dispersive layer disposed on the first surface of substrate, the dispersive layer of thickness less than about 40 μm, covering at least about 70% of the first surface, and being formed from a material having a thermal conductivity of at least 110 W/m ° C., characterized in that a backing layer is disposed on the second surface of the substrate, the backing layer being formed from a material having a thermal conductivity of at least about 145 W/m °C.
