Pictures of Metal Shell Type PTC Heater PTC Heating Element
PTC heating element is composed of PTC ceramic heating element and aluminum tube: galvanized outer pressure plate, stainless steel corrugated spring sheet, galvanized inner pressure plate, single-layer aluminum heat sink, PTC heating sheet, double-layer aluminum heat sink, nickel-plated copper electrode terminal And PPS high temperature plastic electrode sheath
The PTC heating element has the advantages of low thermal resistance and high heat exchange efficiency. It is an electric heater with automatic constant temperature and power saving. The outstanding feature lies in the safety performance. Under any application, the phenomenon of "redness" on the surface of electric heating tube heaters will not occur, When the PTC heating element stops in case of fan failure, the power of the PTC heater will automatically drop sharply due to insufficient heat dissipation. At this time, the surface temperature of the heater is maintained at about the Curie temperature (usually around 250 ℃), so as not to Produce the phenomenon of "redness" on the surface of heaters like the normal electric tubular heating elements.

Use Attention
1) The heating power increases from large to small after power-on, and finally stabilizes. The stable power is related to the use conditions. For the same PTC heater, the power may be several times different if the use conditions are different. The faster the heat dissipation, the greater the stable power; the higher the surface temperature of the PTC, the higher the power.
2) The surface temperature of the PTC heating element is controlled by the PTC itself, or it can be controlled by disconnecting the circuit, but the surface temperature cannot be controlled by adjusting the voltage.
3) PTC itself is highly reliable and has a long life span. However, if the product is improperly assembled, the power and temperature of the product will be unstable.
4) When multiple PTCs are used together, they should be connected in parallel, not in series.
Material: PTC heaters are typically made of ceramic materials that exhibit positive temperature coefficient characteristics. Common materials include barium titanate or other ceramic compositions.
Resistance: As the PTC material heats up when an electrical current passes through it, its resistance increases. This self-regulating property is crucial for preventing overheating.
Temperature Stability: The resistance increase is not linear but follows a sharp upward curve at a certain temperature, providing a self-limiting effect. This means that as the temperature rises, the rate of resistance increase becomes very high, effectively limiting the current flowing through the heater.
Applications: PTC heaters are used in various applications such as space heaters, car seat heaters, industrial equipment, and more. They are popular for their safety features, as the self-regulating nature helps prevent overheating and potential hazards.
Efficiency: PTC heaters are known for their energy efficiency. As the heater reaches the desired temperature, its resistance increases, reducing the power consumption and ensuring that energy is not wasted.
Fast Heating: PTC heaters can heat up quickly due to their ability to draw higher current at lower temperatures and automatically limit it as the temperature increases.
Compact Design: PTC heaters can be designed in compact forms, making them suitable for various applications where space is a consideration.
