High-Performing Vehicle Thermal Management & Automotive HVAC
Today’s vehicles face many temperature challenges due to lighter weight engine cooling systems. DuPont offers a wide range of vehicle thermal management and automotive HVAC solutions.
Controlling temperature is an issue in vehicle thermal management and automotive HVAC. Downsizing engines to improve fuel economy tests traditional thermoplastics to withstand heat, pressures, and chemical exposure. DuPont leading refrigerants offer low global warming potential, which can also be considered for hybrid and electric vehicle battery systems, where the need to control the temperature range is critical.
Lightweighting: DuPont high-performance thermoplastics can withstand the heat, reduce cost, and lower weight in charge air coolers, water inlets, outlets, water pumps, and more.
Sustainability: The new DuPont™ Opteon™ yf, with a GWP of 4 and zero Ozone Depletion Potential, is the leading alternative refrigerant to help automakers meet CO2 standards while creating a comfortable cabin temperature.
Alternative Drive: Hybrid and electric vehicle batteries create heat dissipation challenges. DuPont refrigerants and ducting materials help cool the batteries and regulate the temperature to increase safety and extend the battery life.
