PTC Ceramic Corrugated Heating Element
This corrugated PTC ceramic heating element is designed for stable, fast, and safe electric heating applications. It uses high-performance PTC ceramic chips as the heat-generating core, combined with corrugated aluminum alloy fins to expand the heat dissipation area and improve heat transfer efficiency.
Compared with traditional resistance heating wires, this PTC heating module features automatic constant temperature, lower surface oxidation risk, and built-in overheating protection. It can be widely used in space heaters, air conditioners, dehumidifiers, clothes dryers, industrial hot air systems, and other heating equipment.
We support custom voltage, power, size, lead wire, mounting bracket, and insulation requirements according to customer drawings or application conditions.

Working Principle
The PTC ceramic heating element works based on the positive temperature coefficient effect. When power is supplied, the ceramic chip generates heat and quickly reaches the set temperature range. Once the temperature approaches the Curie point, the resistance increases sharply, which automatically reduces the heating power.
This self-regulating function helps prevent overheating even in abnormal working conditions. The heat is then transferred to the corrugated aluminum fins and dissipated into the air through convection, forming a stable heating system.
Advantages
- High Safety: Built-in overheat protection reduces fire risk caused by continuous high temperature. The flameless heating structure is more suitable for enclosed equipment.
- Stable Heating Performance: PTC ceramic chips show low resistance attenuation, which helps maintain stable heating output even after thousands of hours of operation.
- Fast Heat Transfer: The corrugated aluminum fin structure provides a larger contact area with air, improving heat transfer efficiency and reducing warm-up time.
- Customizable Solution: We can adjust voltage, power, dimension, lead wire position, insulation structure and mounting method according to different equipment designs.
- Lower Maintenance Cost: Reliable ceramic heating structure reduces frequent replacement and after-sales problems, especially suitable for mass production and long-term equipment operation.
