Ceramic infrared heaters

Ceramic infrared heaters consist of resistive heat conductors fully embedded in a suitable ceramic material. Being completely embedded in the ceramic, the energy generated by the thermal conductor can be transferred to the material around it, which not only prevents the thermal conductor from overheating, but also prolongs its service life. The material used to embed the thermal conductor must be insulating and have good absorption and radioactivity in the set infrared radiation range. To meet this requirement, ceramic infrared heaters are available in different geometries.

 

The main body of the ceramic infrared heater is ceramic, which uses a part of the surface as a radiating surface and integrates a heating coil. For ceramic infrared heaters, a thermocouple can also be fixed adjacent to the heat conductor.

 

Infrared is an electromagnetic wave with a wavelength between microwaves and visible light, with a wavelength between 770nm and 1mm, and is an invisible light with a wavelength longer than that of red light. Covers the band of thermal radiation emitted by objects at room temperature. The ability to penetrate clouds and fog is stronger than that of visible light. It has a wide range of uses in communication, detection, medical treatment, military and so on. Commonly known as infrared light.

 

Since infrared has a typical thermal effect, infrared can be used for heating. According to the classification of infrared rays, infrared heaters can be divided into the following three types, short-wave heaters, medium-wave heaters and long-wave heaters. Short-wave heaters are represented by halogen heating tubes, medium-wave heaters are represented by carbon heating tubes, and long-wave heaters are represented by ceramic heaters.

 

  1. Surface average power density

The higher the surface average power density can be, the better the performance of the heater.

 

  1. Extreme temperature

The higher the extreme temperature, the better the temperature resistance, so the longer the service life is better at the same temperature, the higher the extreme temperature, the better the heater performance.

 

  1. Weight

Generally speaking, the lighter the weight of the same type of ceramic heater, the higher the heating efficiency.

 

  1. Heating and cooling performance

The faster the heating and cooling, the better the heater performance.

 

  1. Service life

Service life is an important indicator of heater performance parameters. The longer the service life, the better its performance.

 

  1. energy saving effect

Obviously, the better the energy saving, the better the heater performance.

 

  1. Consistency

The higher the consistency of the parameters (heating and cooling performance, weight, etc.) of the same type of heater, the better the performance of the heater.

 

Factors unrelated to heater performance

The primary condition of the ceramic infrared heater is heating. Therefore, the higher the ceramic emissivity, the better its performance. The brightness of the glaze has nothing to do with the emissivity. Moreover, the glaze is easy to melt at high temperatures, so it is not the brighter heating. better.
