Product Description
Self-Limiting Temperature Corrugated Aluminum PTC Heating Element
Our corrugated fin PTC ceramic heating assembly is engineered for embedded integration inside electric heating appliances. We optimize the matching between ceramic heating chip and corrugated aluminum radiator, solving common issues of traditional heaters including slow heat dissipation, overheating, and short service life.
Strict batch testing is implemented for insulation, power stability, and temperature consistency before delivery. The heating assembly supports flexible customization of wiring terminals, mounting ear positions, and insulation structure, perfectly matching the inner installation space of customers' finished equipment.
Key Characteristics
- Built-in passive temperature limiting function, no extra thermal protector required for regular ventilation scenarios
- Corrugated fin structure expands air contact area, accelerating heat dissipation to avoid local high temperature accumulation
- Multi-layer composite insulation structure improves dielectric strength, adapts to humid, dusty working environments
- Optimized crimping process for lead terminals, excellent vibration resistance for transportation and equipment operation
- Narrow tolerance of power output among bulk products, convenient for customers' standardized assembly production
Production Technology
The manufacturing process includes raw material inspection, ceramic high temperature sintering, electrode printing, fin hydraulic pressing, multilayer insulation coating, lead terminal crimping, 4-hour power aging test, and withstand voltage detection. Every batch undergoes rigorous screening to eliminate unqualified units, ensuring thermal conduction efficiency and reducing after-sales risks for bulk orders.

Applications
Apart from conventional household heating equipment like space heaters, clothes dryers, and dehumidifiers, this heating assembly also fits electronic cabinet constant temperature heating, refrigeration equipment defrosting, greenhouse micro heating, vending machine internal dehumidification, and laboratory small constant temperature devices. It covers household, commercial, industrial, and horticultural heating demands.
Key Advantages
- Strong environmental adaptability: multilayer insulation structure enables stable operation under high humidity and slight dust conditions
- Convenient for mass assembly: diversified terminal and mounting schemes reduce customers' fixture transformation costs
- Low batch deviation: strict aging & electrical testing keep consistent performance across large quantity goods
- Built-in over-temperature protection: decreases customer requirement for peripheral safety components, lowering overall solution cost
Frequently Asked Questions
