Nano infrared electric heating ring

Abstract

The invention belongs to the technical field of electric heating devices, and specifically relates to a nano-infrared electric heating ring; it includes a main body of the electric heating ring, and the main body of the electric heating ring includes a far-infrared coating, a heat conducting layer, a nano electric heating layer, a heat insulation layer and a shell from the inside to the outside. , the main body of the electric heating coil is cylindrical in shape; the nano-electric heating layer is spliced ​​by several nano-carbon fiber heating plates, and the nano-electric heating layer and the heat insulation layer are coated with high-temperature resistant and flame-retardant glass glue; the heat-conducting layer and the nano-electric heating layer There is a silver layer between them; the outer surface of the shell is covered with a radiation-proof coating; it can effectively save electric energy, avoid heat energy loss and waste, have no harmonic interference to other equipment in the grid, have a long service life, and are highly efficient and environmentally friendly.

Description

technical field [0001] The invention belongs to the technical field of electric heating devices, and in particular relates to a nanometer infrared electric heating coil. Background technique [0002] At present, the commonly used electric heating power is usually a spiral resistance heating coil. The resistance wire is connected to the power supply to generate thermal effect, and the heat is transferred through direct contact conduction. Due to structural limitations, the heating ring cannot be equipped with a tight heat insulation device, so when the heating ring is working, the surface temperature is high, and a large amount of heat energy is dissipated into the environment, resulting in heat loss; there are also heaters using high-frequency electromagnetic heating in the prior art , High-frequency electromagnetic waves will cause harmonic interference to the power grid, affecting the working status of other equipment and shortening the service life.
