NOVELTY - The utility model claims a honeycomb type module type heating piece and heating device, comprising a heating film and two sides of the heating plate, the heating film is graphene heating film, the heating film is densely provided with a through film hole and is honeycomb-shaped, the heating film opposite to the two end face edge is provided with two conductive copper foil; two of the conductive copper foil respectively provided with a power supply anode end and a power supply cathode end; the heating plate is pressed on the two sides of the heating film. The utility model is provided with a unique design of the film hole, realizing the air emitted from the film hole and the surface of the air, the air of the cold place will flow to supplement to the film hole, so as to improve the speed of the cold and heat exchange, the honeycomb cold and hot alternating effect, the same voltage, the same current; under the same power and the same room temperature condition, the heat exchange speed of the air is improved by 10 %-20 %; the service life of the product can reach more than twenty times; the surface insulating performance can reach to 5-8 KV.
