Abstract

The invention relates to a nano-fiber heating plate. The nano-fiber heating plate comprises a heating plate body, and metal electrode sheets, which are fixedly connected with the two opposite side edges of the heating plate body, and are connected with an external power supply. The heating plate body is formed by an upper insulation wear-resistant layer, a lower insulation wear-resistant layer, and a nano-fiber heating film layer disposed between the above mentioned two layers. The two side edges of the nano-fiber heating film layer are contacted with the metal electrode sheets The nano-fiber heating plate is advantageous in that the inner interlayer of the heating plate body is the thin nano-fiber heating film layer, and the heating plate body is a surface-shaped heating body, and has a high-quality far-infrared radiation capability and a high electric energy-heat energy conversion rate, and the corresponding cost is reduced by 60-70% by comparing with the conventional heating body; the upper layer and the lower layer of the heating plate body are the insulation wear-resistant layers made of PET, has good heat permeability, and is capable of insulating water vapor and air, and has a good protection function for the interlayer, namely the nano-fiber heating film, and at the same time, the heat-resistant performance and the mechanical performance of the PET are good, and the PET is used as the surface layer, and then the heating plate has insulation, wear-resistant, and impact-resistant characteristics.

Description

technical field [0001] The invention belongs to the field of electric heating plates, and in particular relates to a nanofiber heating plate. Background technique [0002] Most of the existing heating materials are linear or massive heating elements, which have low electrothermal conversion rate, low heat transfer efficiency, and uneven heating, so they have disadvantages such as high energy consumption, high cost, and uneven surface temperature. When the heating plate is used as the heating element in the oven to dry the agricultural products, it is also necessary for the heating plate to have good insulation, wear resistance and impact resistance, so as to prevent leakage or Friction damage or impact damage due to contact of the heating plate itself with produce. Contents of the invention [0003] The invention provides a nanofiber heating plate, which aims to overcome the shortcomings of the linear or block hair body in the prior art, and meanwhile has the characterist...
