Description
The Corrugated PTC Air Heater is an advanced heating module based on a positive temperature coefficient (PTC) ceramic heating element. Its most notable feature is the corrugated aluminum alloy fin housing surrounding the heating core. This design is not merely aesthetically pleasing; it significantly increases the surface area in contact with the air, greatly improving heat exchange efficiency. Through forced convection (driven by a fan), it rapidly heats cold air into a powerful, stable hot air output, making it an efficient and safe choice for modern electric heating applications.
Specification
Product Name: Electric PTC Air Heater
Rated voltage: 12-600VDC
Power: 300-500W
Application: Suitable for heating of automobile air conditioners and other similar equipment.
Features
1. High Efficiency and Energy Saving, High Heat Conversion Rate:
Corrugated fin design: The key to its high efficiency. The corrugated structure acts like the "ribs" of a radiator, creating a large effective heat dissipation area. This allows heat to be quickly and efficiently carried away by the air, resulting in extremely high heat conversion efficiency, rapid temperature rise, and relatively low air resistance.
Self-Controlled Temperature Energy Saving: Utilizing the inherent characteristic of PTC technology—automatic constant temperature control—it achieves maximum power during cold start-up, resulting in rapid heating. Upon reaching the predetermined temperature, the resistance increases, and the power automatically decreases, consuming only the energy required to maintain heat, thus avoiding energy waste.
2. Intrinsically Safe, Reliable and Durable:
Overheat Protection: Thanks to its self-limiting temperature control, the heater will not overheat or burn even in the event of abnormalities such as fan failure or air duct blockage, fundamentally eliminating fire hazards and offering a safety level far exceeding that of traditional metal resistance wire.
No Open Flame, Long Life: PTC ceramic elements operate without open flames or red heat, are resistant to oxidation and corrosion, and possess stable physical and chemical properties for an extremely long service life.
3. Compact Structure and High Integration:
The entire module typically integrates the PTC chip, corrugated fins, insulation material, and metal frame into a single, sturdy unit. This compact structure and high power density make it ideal for installation in ventilation ducts or HVAC systems of various equipment.
4. Stable Operation and Strong Adaptability:
The heat output automatically matches the wind speed and inlet temperature to maintain a stable outlet temperature. It also exhibits good adaptability to power supply voltage fluctuations and operates normally over a wide voltage range.
Application
This type of PTC heater is widely used in applications requiring efficient and safe forced hot air:
New Energy Vehicles:
Passenger Compartment Heating: As the core heating component of electric vehicle air conditioning systems, it replaces the engine waste heat of traditional fuel vehicles to provide comfortable warm air inside the vehicle.
Battery Preheating: In low-temperature environments, it preheats the power battery pack, ensuring the battery is within the optimal operating temperature range, improving charging and discharging performance, and extending battery life.
Industrial Equipment:
Industrial Ovens/Drying Equipment: Used for drying painted workpieces, building materials, agricultural products (such as tea and mushrooms), and textiles, providing uniform, controllable hot air.
Air Heaters and Hot Air Curtains: Used to heat air or create insulating air curtains in spaces such as factory workshops, warehouses, and shopping mall entrances.
Home and Commercial Appliances:
Home Dryers: Used to heat the air inside the dryer, with safety features that prevent clothing from overheating and fire.
Bathroom Heaters: Provide rapid bathroom heating, and their safety features are particularly suitable for humid environments.
Fresh Air Systems and Air Conditioning: These heaters serve as a supplemental heat source for fresh air systems or central air conditioning units with heating functions.
