Foot-warming heating sheet with nano carbon electric heating films

Abstract

The invention provides a foot-warming heating sheet with nano carbon electric heating films. Nano carbon electric heating long-strip-shaped film sheets are clamped in a heating block manufactured by an upper insulating material layer, a lower insulating material layer and film sealing material layers at equal intervals; electrodes at the two ends of each nano carbon electric heating long-strip-shaped film sheet are respectively connected with a copper foil; one end of each copper foil at the electrodes is connected with a leading-out wire; the upper and the lower film sealing material layers are coated with binding agents, so as to flatly seal and fix the nano carbon electric heating long-strip-shaped film sheets and the copper foil already connected therewith in the heating film block; and a leading-out wire reinforcing block is arranged on the heating film block which is bound and fixedly sealed. Compared with a traditional heating sheet element, the foot-warming sheet element on an electric warming oven, which is provided by the invention, saves more energy by above 50 percent and achieves just the same heating effect, the heating speed is greatly increased and the far infrared effect is very remarkable; and the foot-warming sheet is already used in electric warming ovens on a large scale and economic and social benefits are created.

Description

technical field [0001] The invention relates to the technical field of electric heating elements, in particular to a nano-carbon electrothermal film foot warmer. Background technique [0002] At present, there are many electric heating materials used in electric heating furnaces, from the earliest metal resistance wire heating element to the later non-metallic resistance heating materials, such as graphite carbon cloth, graphite carbon rod, etc. In recent years, electric heating film has been successfully developed material, which greatly improves the electrothermal conversion rate of electric heating materials. At present, one kind of electric heating film in China is made of metal pressing film, which is wrapped with insulating material to make rigid electric heating film and electric heating plate.

Problems solved by technology

[0002] At present, there are many electric heating materials used in electric heating furnaces, from the earliest metal resistance wire heating element to the later non-metallic resistance heating materials, such as graphite carbon cloth, graphite carbon rod, etc. In recent years, electric heating film has been successfully developed material, which greatly improves the electrothermal conversion rate of electric heating materials. At present, one kind of electric heating film in China is made of metal pressing film, which is wrapped with insulating material to make rigid electric heating film and electric heating plate. Secondly, powder electric heating materials such as Conductive silver powder, conductive nickel powder, graphite powder, conductive glass microspheres, etc. are used to make soft electric heating films. However, the current rigid electric heating films, electric heating plates, and electric heating soft conversion rates are relatively low. Manufacturers of electric heating furnaces urgently need to find an energy-saving The effect is good, and the electric heating material with health care function for the human body has been widely concerned with the special and excellent performance of the birth of nanomaterials.

The research of nano-carbon material electrothermal film is successful and has the international advanced level. However, due to the absence of its application products, this technology cannot bring economic benefits to enterprises, and it is in an increasingly difficult and embarrassing situation. The study found that nano-carbon material electrothermal film has Excellent electrical properties, thermal properties, physical and chemical properties, especially with extremely high electrothermal conversion rate, can produce far infrared rays and other characteristics, specially developed nano-carbon electrothermal film foot warmer of the present invention, used for electric heating stoves The warming part of the foot has achieved very good results
