Nissan Tests Paint That Can Cool Cars
Published: August 9, 2024, 7:38 AM
Nissan is currently conducting experiments on a revolutionary paint that boasts the ability to cool vehicles. In November 2023, the company initiated a 12-month trial at Tokyo‘s Haneda International Airport, applying the paint to their electric NV100 model.
Early findings are highly promising, with the painted NV100 registering a 12-degree cooler body temperature and a 5-degree cooler interior temperature compared to vehicles with conventional paint.
A cooler interior not only enhances passenger comfort but also offers practical advantages. By reducing the reliance on air conditioning, fuel consumption in gasoline vehicles is minimized, while electric cars benefit from preserved battery charge and increased autonomy.
Developed in collaboration with Radi-Cool, a specialist in radiant cooling technologies, this paint incorporates synthetic metamaterials with unique properties not found in nature.
The cooling mechanism of this innovative paint is attributed to two microscopic particles. One particle reflects the near-infrared rays responsible for heating traditional paint, while the other generates electromagnetic waves that dissipate heat. This combined action effectively reduces the temperature of the car’s exterior surfaces, including the roof, hood, doors, and panels.
