What's the Ceramic Heater 1？
The core definition of the Ceramic Heater
The ceramic heateris an electric heater that uses a PTC ceramic Heating Element as its heat source. Here, "ceramic" does not refer to the common insulating ceramic, but rather a specially made functional ceramic with a positive temperature coefficient effect.
The Working Principle of Ceramic Heater
1. Startup stage (cold state): When the power is turned on, the resistance of the PTC element is very low and the current passing through it is high, resulting in a large power and a rapid increase in temperature.
2. Self-regulation stage (constant temperature): When the temperature rises to the Curie temperature point of the PTC material, its resistance increases sharply, causing the current passing through it to automatically decrease, and the power also drops.
3. Dynamic equilibrium: If the external temperature drops (such as being blown by the wind), the temperature of the PTC element slightly decreases, and its resistance will automatically decrease, the current and power will increase again to compensate for the loss of heat. Conversely, if the environmental temperature rises, the resistance will increase and the power will decrease.
4. Final state: Through this self-regulation, the PTC heater can stabilize its own temperature within a specific range and will not continue to heat indefinitely.
The main features of Ceramic Heater
Due to its unique working principle, ceramic heaters possess several distinct advantages:
1. Self-regulating temperature, extremely safe: This is its most crucial advantage. Even without an additional temperature controller, it will not overheat and catch fire, thus avoiding the risk of fire. If the Fan malfunctions and prevents heat from dissipating, it will only reduce power instead of burning out.
2. Energy-efficient and highly effective: Once the set temperature is reached, it can automatically reduce power to maintain the temperature, avoiding continuous full-power heating like traditional resistance wire heaters, thereby saving electricity.
3. No open flame, long lifespan: The heating process is "thermal radiation", not the resistance wire getting red-hot. Therefore, the components themselves do not oxidize and have an extremely long lifespan.
4. Rapid temperature rise: The initial power is high, enabling it to quickly reach the working temperature.
5. Compact structure, flexible design: The PTC heating element can be made into various shapes (such as honeycomb, strip, or sheet), facilitating integration into different products.
