The present invention for solving the problems of the technologies described above taked technical scheme is: a kind of cross-ventilation-type electric hot plate based on carbon fiber heating, is characterized in that: it comprise connect successively heat-insulation layer, troposphere, zone of heating and decorative layer; Wherein zone of heating is formed alternately by carbon fiber and wire; Troposphere comprises a cavity, and cavity side, to being provided with air inlet and air outlet, is provided with undulatory baffler in cavity.
By such scheme, described decorative layer comprises PET film.
By such scheme, the profile of electric hot plate is rectangle, and four corners are smooth fillets.
By such scheme, described heat-insulation layer is polyurethane foam material.
By such scheme, described heat-insulation layer is white, and described zone of heating is black.
Beneficial effect of the present invention is:
1, electric hot plate of the present invention is by electrically heated mode environmentally safe, environmental protection, can be used as decoration painting and hangs on the wall, not affect the appearance and easy to maintenance, according to the number of careat determination electric hot plate; Troposphere is set cleverly, undulatory baffler is utilized to increase the area of air and heating plate, when air flows through baffler, the passive disturbance of air, make to be that the air of laminar condition becomes turbulence state originally, thus the heat exchange of strengthening air, the hot exchange power of unit are is increased, improves the efficiency of heating surface; By increasing heat-insulation layer, preventing heat from passing to metope, reducing thermal loss; Material of the present invention is simply common, and cost is low.
2, PET film is selected to be used for decorating, its surface can be that landscape painting, Brush calligraphy etc. are as art appreciation product, its impact strength is 3-5 times of other films, folding resistance is good, can oil resistant, resistance to fat, resistance to diluted acid, diluted alkaline, resistance to most of solvent, has good high-and low-temperature resistance performance and excellent choke, water, oil and peculiar smell performance simultaneously.
3, select common decoration painting shape as the shape of electric hot plate, air attractive in appearance, four corners are smooth fillets, thus increase the speed of gas in flowing, reduce the unnecessary resistance that gas flow produces.
4, the color of heat-insulation layer is white, again reduces the loss that heat transmits to metope; Zone of heating color is black, thus strengthens the heat absorption capacity on surface, improves heat transfer efficiency.
