What is a ptc heating element?
It consists of galvanized outer pressure plate, stainless steel corrugated spring piece, galvanized inner pressure plate, single layer aluminum heat sink, ptc heating piece, double layer aluminum heat sink, nickel plated copper electrode terminal and pps high temperature plastic electrode sheath. This product has improved heat dissipation due to the use of u-shaped corrugated fins. It combines the advantages of adhesive and mechanical, and fully considers the various thermal and electrical phenomena of the ptc heating element 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. One of its outstanding features is the safety performance, that is, 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 the Curie temperature (generally around 250 ° C), so that the surface of the heater such as the electric heating tube is not "reddened".
Rapid temperature rise, self-control temperature and long service life when the fan fails
Wide voltage range, can be designed between 12V-380V according to needs
Easy to design, can be designed from low power to high power, the shape can also be designed according to requirements
Not burning, safe and reliable

PTC heating element advantages
1. The rapid heating of the aluminum sheet is more compact and the heat effect is higher.
2. Health and environmental protection without glue bonding is healthier.
3. Long and durable, no oxidation, and the service life is up to 6000 hours.
4. PTC heating element thermal efficiency up to 99%
What material is the PTC heater?
The PTC heating element refers to an automatic temperature-controlled PTC ceramic heating element, which is a special ceramic material. The principle of PTC heating element constant temperature heating is:
When the PTC heater is electrified, because the resistance at room temperature is small, the starting current is large, which can make the PTC heater heat up quickly and lead to its resistance value increasing rapidly into the jump zone. At this time, the current through the PTC heating element is very small, so that the surface temperature of the PTC heating element is always kept constant, and the temperature is only related to the Curie temperature and the applied voltage of the PTC heating element, and has nothing to do with the ambient temperature.
Its production process is as follows:
PTC component application
Air conditioners, hot air curtains, dehumidifiers, dryers, dryers, heaters, Yuba, cars, etc. need to provide warm air on the equipment.
