Far-infrared planar heat generator and production method thereof

Abstract

The invention discloses a far-infrared planar heat generator and a production method thereof. The far-infrared planar heat generator comprises a heat generating substrate, an upper insulating heat conducting layer disposed at the upper end of the heat generating substrate, and a lower insulating heat conducting layer disposed at the lower end of the heat generating substrate, wherein the electrodes are disposed on both ends of the heat generating substrate; the heat generating substrate, the upper insulating heat conducting layer and the lower insulating heat conducting layer are each a sheet-like structure; the heat generating substrate is formed by mixing graphene powders, nano-scale carbon powders and nano-scale PI powders at high temperature and high speed and then tape casting the same; the upper insulating heat conducting layer and the lower insulating heat conducting layer are both composed of pure PI films; the heat generating substrate and the upper insulating heat conductinglayer are laminated into one body, and the lower insulating heat conducting layer and the heat generating substrate are laminated into one body. The far-infrared planar heat generator and the production method thereof according to the invention have the advantages of low production cost, high heat generation efficiency, reduced power waste, and reduced influence on a object to be dried.

Description

technical field [0001] The invention relates to the technical field of far-infrared heating, in particular to a far-infrared planar heating element and a production method thereof. Background technique [0002] Drying devices are used in agricultural production, Chinese herbal medicine production, civil heating and medical physiotherapy and other fields. After the grain and Chinese medicinal materials are harvested, they need to be dried for storage and rolling. In order to complete the drying process as soon as possible, people use drying equipment for processing. The drying equipment in the prior art adopts an upright baking oven, which uses coal, diesel oil or resistance wire to generate heat as a heat source. Its disadvantages are: a baking oven using coal, diesel or electricity as a heat source will consume a lot of fuel, and the production cost is high; the heating efficiency of the resistance is low, wasting electric energy; and the conventional baking device will c...
