The PTC heating element is also called a PTC heater, and is composed of a PTC ceramic heating element and an aluminum tube. This type of PTC heating element has the advantages of small thermal resistance and high heat exchange efficiency, and is an automatic constant temperature and power saving electric heater. The outstanding feature is the safety performance. Under any application, the surface of the electric heating tube heater will not be reddened, so that it will not cause burns, fires and other safety hazards.

Introduction
The PTC heating element product uses a u-shaped corrugated heat sink to improve its heat dissipation rate. It combines the advantages of adhesive and mechanical, and fully considers the various thermal and electrical phenomena of ptc heating elements during operation. It has strong bonding force, excellent heat conduction and heat dissipation performance, high efficiency, safety and reliability. This type of PTC heater has the advantages of small thermal resistance and high heat exchange efficiency, and is an automatic constant temperature and power saving electric heater. Its outstanding feature is its safety performance: When the fan fails to stop, 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 Curie temperature (generally around 250 degrees Celsius), thus avoiding the phenomenon of "reddening" on the surface of heaters such as electric heat pipes.



Composition structure
The PTC heater consists of galvanized external pressure plate, stainless steel corrugated spring plate, galvanized internal pressure plate, single-layer aluminium radiator, PTC heating plate, double-layer aluminium radiator, nickel-plated copper electrode terminal and PPS high temperature plastic electrode sheath.

Advantage
1. Aluminum sheet with fast heating is more compact and more efficient.
2. Healthy, environmentally friendly, glue-free bonding is healthier.
3. Ultra-long durability without oxidation, service life up to 6000 hours.
4. The thermal efficiency of PTC heater is as high as 99%.
