PTC material is a special type of semiconductor material that has a significant increase in resistance as the temperature rises, meaning it has a positive temperature coefficient (PTC) property.
The working process：
1. Electric Heating:
- When the PTC heater is powered on, current flows through the PTC material.
- Due to the relatively low initial resistance of the PTC material, current can flow smoothly and generate heat, causing the PTC material and its surrounding environment to begin to heat up.
2. Resistance Change and Self-Limiting Temperature:
- As the temperature rises, the resistance value of the PTC material gradually increases.
- When the temperature reaches a certain level, the resistance value of the PTC material suddenly increases,
Advantages of PTC Heater Application:
Fast Response: PTC heaters can quickly respond to temperature changes and achieve rapid heating.
Uniform Heating: Due to its self-regulating properties, PTC heaters can maintain a uniform heating temperature.
Safe and Reliable: Even under non-normal operating conditions, the input power can be reduced significantly due to the self-regulating action of the PTC element, avoiding overheating and unexpected situations.
Wide Application: PTC heaters are widely used in various fields such as household appliances, automobiles, medical care, military industry, and have good application prospects in temperature control.
