The principle of nano far-infrared energy-saving electric heating coil

Infrared nano energy saving heating coil. The direct effect of converting radiated heat energy into far-infrared heat energy through electric heating coating is to increase the temperature of the heated object, reduce the temperature of moisture loss, and enhance the heat absorption rate of the heated object; Reduced thermal energy loss and achieved energy-saving goals. Nano infrared electric heating coil is a self-developed plastic mechanical auxiliary heating equipment. Adopting a new type of nano infrared heating element, the electric heat exchange efficiency reaches up to 99.8%. The use of infrared unidirectional radiation greatly improves the heat transfer efficiency between the heating element and the cylinder. The space adopts special gas condensation felt adhesive, with a low thermal conductivity of 0.013 w/m. K, Ensure that the surface temperature of the electric heating coil is not higher than 70 ℃, the third generation of thermal radiation, and the surface coating can ensure that the surface temperature is as low as 50 ℃, thereby improving the traditional heating coil's electric heating conversion efficiency. The low pass, high thermal efficiency, and high surface temperature are fatal drawbacks, which can not only achieve energy savings of more than 30%, but also improve the working environment of the workshop.

The nano infrared heating coil itself becomes a far-infrared radiation heat source. With the increase of its surface temperature, the temperature gradient increases, which enhances the thermal conductivity of the heated object and greatly improves its heat absorption ability. The direct effect of converting radiated heat energy into far-infrared heat energy through an electric heating layer is to increase the temperature of the heated object, reduce the temperature of water loss, and increase the heat absorption speed of the heated object; Reduced heat loss and achieved energy-saving goals. The principle of nano electric heating coil is as follows:

1. Objects with different characteristics have different infrared characteristics (i.e. wavelength), and infrared with different characteristics is easily received by objects with the same characteristics, that is, the infrared emitted by solid substances is easily absorbed by solids and not easily absorbed by gases.

2. Heat transfer forms: radiation, conduction, and convection.

3. Thermal energy is mainly transmitted in the form of radiation at high temperatures (90%), and its radiation intensity is proportional to the fourth power of temperature.

The absorption capacity of radiant heat energy is directly proportional to the surface blackness of the heated object.

The thermal conductivity of the heated object is directly proportional to the temperature gradient on the surface and inside of the object, and inversely proportional to the thermal resistance.

6. Heating performance: Using infrared nanomaterials for radiative thermal conductivity;

7. Thermal insulation performance: Keep the external temperature between 45-70 ℃, and prevent workers from being affected by high temperatures; Can cause whisker damage (can be personally tested), resulting in a significant decrease in indoor temperature;

8. Heating speed: The material is heated for 45 seconds (1/3 faster than traditional heating speed);

9. Service life: Ensure continuous use for more than 5 years. Due to the long heating time of nanoscale materials at a high temperature of 1000 ℃, the service life can reach 20000 hours. The heating temperature can generally not exceed 350 ℃ by injection molding plants, so this is a long-term light load state. So it can guarantee two years!
