Structural layout and performance characteristics of ceramic heaters
Because the ceramic heater adopts the ceramic wire threading method, the imported round wire ceramic is used as the heating element, and it is bent into a spring to penetrate into the ceramic coil; the outer cover is made of stainless steel, and high temperature insulation cotton is used in the middle to prevent temperature leakage , This structure makes the power of the product much higher than that of ordinary electric heaters.
Ceramic heater manufacturers
For ceramic heaters, its ceramic strip is a kind of high-frequency ceramic, so it has the characteristics of fast heat transfer, hard and not fragile, high temperature, non-deformation and not easy to aging, and the electric heater naturally inherits these advantages. In addition, a heat preservation device should be added to the heat dissipation surface of the electric heater, and the inner heat dissipation surface is sintered with infrared rays, so that the purpose of energy saving can be achieved.
The electric heater is generally controlled by the contact of the temperature control instrument to control its internal AC power on and off. When the temperature of the electric heater is lower than the set temperature, the contact of its temperature control instrument is turned on, and the temperature Rise; when the temperature of the electric heater is higher than the set temperature, the contact of the temperature control instrument is disconnected and the temperature drops to ensure that the electric heater works within a certain temperature range.
If the electric heater has a burn-out failure, the operator cannot determine whether the electric heater is normally cut off due to an increase in temperature or the electric heater is cut off due to the heater's open circuit failure. Due to the thermal inertia of the heater, the internal temperature of the electric heater needs to be delayed for a period of time before cooling down. In this way, when the operator of the electric heater discovers that the product is unqualified, it has caused waste and affected the quality of the product.
