NF PTC Air Heater for Electric Vehicles

Short Description:

The PTC air heater in electric vehicles serves two main functions: defrosting critical components and protecting the battery in cold conditions. It directs warm air to areas like the windshield and sensors, ensuring clear visibility and proper ADAS performance. It also maintains the battery’s optimal temperature, improving efficiency and charging speed. The self-regulating PTC technology reduces power use and prevents overheating without complex controls. Its compact and reliable design makes it essential for vehicle safety, comfort, and system stability in different climates.

Power: 3.5kw

Rated Voltage: 333V

Product Description

With increasing global emphasis on environmental protection, the development of electric vehicles has attracted significant international attention and is rapidly entering the mainstream automotive market. Unlike vehicles with internal combustion engines, which utilize waste engine heat for cabin heating and therefore do not require additional heating equipment, electric vehicles necessitate dedicated heating systems. High-voltage positive temperature coefficient (PTC) heaters are capable of delivering the required heating power, efficiency, and reliability, making them the preferred solution for this application.

The heating element of the PTC heater assembly is positioned in the lower section of the unit and operates based on the inherent heating characteristics of the PTC sheet. When energized at high voltage, the PTC sheet generates thermal energy, which is conducted to the aluminum radiator fins. The heat is then dissipated across the heater surface by an air box fan, which draws in ambient air, absorbs the heat, and expels warm air.

ThePTC air heater assembly features a one-piece design that integrates the controller and heating unit into a single compact module. This design results in a product that is compact, lightweight, and easy to install. The PTC heater itself has a streamlined structure with an optimized layout, enabling efficient use of internal space. Safety, waterproofing, and ease of assembly have been carefully considered in the design to ensure reliable and stable operation under normal working conditions.
