NOVELTY - The invention claims a graphite heating box, comprising a box body and a box cover, the inner wall of the box body and the box cover is provided with a wave barrier, the wave separating layer and box body, inner wall of the box cover is provided with the gap is provided with a refrigerating, insulating layer away from the wave inner wall is provided with a graphite heating film. heating film of graphite because the relatively high conversion of far infrared, it can effectively realize the electric energy to the far infrared ray transformation, under the condition of the two ends of the graphite heating film electrifying electrode, carbon molecular heating film of graphite in the resistance generating phonons. ion and electron molecular group by carbon generated between friction and collision with each other to generate heat energy, heat energy and by controlling the wavelength far infrared ray of 5-14 microns uniformly radiated out in a planar manner, effectively heating energy total conversion rate is more than 99%. simultaneously adding the superconducting property of the graphene material special and ensure stable heating performance. it can be widely suitable for the insulating and heating of article storage.
