Hyundai Motor has introduced the world’s first Nano Cooling Film for vehicle windows which significantly improves interior cooling. The film utilizes a nanostructure for enhanced heat dissipation, particularly suitable for hot, dry climates. In a real-world test, the film was applied to 70 cars in Lahore, Pakistan. This transparent film is more efficient than traditional tint films, blocking heat while remaining clear and not impeding night vision. Its three-layer composition selectively blocks or emits different solar heat wavelengths, keeping the interior cooler by reflecting incoming heat and radiating internal heat outside. The film can also be used with regular tint films in regions with fewer tint regulations, boosting its cooling capabilities.
Hyundai Motor unveiled its Nano Cooling Film during the ‘Nano Tech Day’ media event in July 2023, emphasizing its commitment to integrating advanced material technologies into future mobility products. The effectiveness of the Nano Cooling Film was highlighted by its capacity to significantly reduce interior vehicle temperatures. In tests, this innovative film decreased the temperature by nearly 51.8°F around the driver’s head compared to traditional tint film and over 53.6°F versus vehicles without tint. Notably, the temperature of the vehicle’s crash pad was over 59°F cooler with Nano Cooling Film than with conventional tinting, and 71.6°F cooler compared to vehicles without any window tinting.
The product is tailored to local regulations that disallow tinted windows for security purposes, by reducing vehicle interior temperatures by over 50°F without darkening the glass. Hyundai’s initiative, which provides the film application free of charge, is designed to enhance comfort for drivers in Lahore’s extreme summer heat, potentially exceeding 122°F, while also reducing the reliance on air conditioning, to lower energy consumption. The campaign will also collect data to ensure the quality of the product before considering mass production.
