Novel heating film

Abstract

The invention discloses a novel heating film, which comprises a heating film body, a heating layer, conductive carbon fibers and conductive metal wires, wherein the heating layer is arranged inside the heating film body, conductive coatings and longitudinal tensile fibers are arranged inside the heating layer in an alternating manner, the conductive carbon fibers are fixed inside the conductive coatings, both sides of each of the conductive coatings, the conductive carbon fibers and the longitudinal tensile fibers are fixedly connected with the conductive metal wires, the right end of each conductive metal wire passes through an insulated sealing plug to be connected with a conductive wire in series, the insulated sealing plugs are fixedly connected with the heating film body, the outer wall of the heating layer is coated with a heat resistant layer, the outer wall of the heat resistant layer is adhered with a thermal insulation layer, and a PET insulating film is arranged between the thermal insulation layer and a waterproof protective film. The novel heating film has the advantages of ultrathin thickness, uniform heat radiation, high durability, energy conservation and environmental protection; and the heating film body is fast in temperature rising speed and high in heating temperature through the cooperative use of the conductive coatings and the conductive carbon fibers.

Description

technical field [0001] The invention relates to the technical field of heating film equipment, in particular to a new type of heating film. Background technique [0002] The heating film is a planar heating element composed of an electrical insulating material and a heating resistance material packaged in it. It is a new electric heating element in recent years. It absorbs the characteristics of two electric heating elements, PTC and conductive paint. It is mainly used for indoor heating and environmental temperature maintenance. It converts electrical energy into thermal energy during work, and transmits the thermal energy outward mainly in the form of radiation. However, the existing heating film has a slow heating rate and the heating temperature cannot reach a high value for the time being. And the shortcoming of fast heat dissipating speed after power failure, not durable enough and energy-saving environmental protection, can't satisfy people's demand. Contents of the...
