A keen market sense coupled with tightly aligned processes, manufacturing excellence and fast implementation makes BorgWarner a market and product leader. Our thermal management systems are designed to meet the needs of our global customers while also improving fuel economy and reducing emissions.
Heaters play a key role in any vehicle, allowing liquids and air to be heated for optimal engine operation and passenger comfort – even more so in hybrid and electric vehicles than in internal combustion cars. BorgWarner offers efficient and powerful air and liquid heating solutions for a variety of applications.
BorgWarner’s high voltage air heater delivers a comfortable interior and safety through quick window defrosting for applications with limited waste heat such as electric vehicles. Thanks to its very compact and modular design, it can easily be integrated into existing structures within the vehicle.
Batteries have a narrow optimal temperature range. BorgWarner’s specially developed high voltage coolant heaters have been developed to keep the core components of hybrid and pure electric vehicles at temperatures that facilitate maximum charging efficiency, durability and driving range. It delivers heat to the interior quickly and clears the ice from windows in short order.
Secondary air systems are important for gas cold-engine starts when the majority of hydrocarbon emissions are created. The complete system (including pump, valve, bracket, relay and hoses) provides additional advantages such as low noise and vibration. Air pump flows can be tailored to meet specific customer requirements. BorgWarner has a diverse list of global electric air pump (EAP) customers.
For optimal management and control of heat flows within and around the engine, BorgWarner offers a wide range of products of fixed- and variable-temperature wax thermostats.
Characterized by a broader working range than conventional wax thermostats featuring a fixed opening temperature, BorgWarner’s electrically heated thermostats adjust the internal engine temperature as needed in response to signals from the engine control unit, thereby reducing fuel consumption.
Wax thermostats are proven million times and still in use to control and regulate the coolant temperature. Conventional wax thermostats are regulating just with the wax liquefying when the coolant temperature is rising or falling. Electrically heated wax thermostats offer a wider operating range and can be triggered when the engine is exposed to specific load conditions.
Airflow management plays a key role in cooling the engine. Our polymer cooling fans range from optimized axial flow fans and ring-fans for specific installations, to new hybrid designs to cover future cooling demands. New features include improved aerodynamics and durability in the same light-weight package. Using technology-focused design methods such as FEA, CFD and MoldFlow™, performance and reliability are optimized. BorgWarner’s Guide Vane design provides optimized air-flow potential through its world-class efficiency improvements and unique diffuser design. This unique design requires lower torque than fans operating in a traditional shroud, translating into more power to the wheels.
Making full use of the additional power available from a 48V power supply, BorgWarner’s 48V eFan family is based on a scalable BLDC motor design with integrated and actively cooled electronics. Primarily designed for the Off-Highway and SUV/LCV segments, our electric fans provide trouble-free operation as well as optimal airflow and cooling performance even under severe conditions.
Combining the advantages of an electrical fan and mechanical fan drive regarding fuel efficiency, performance, noise and system integration, BorgWarner’s Dual Mode Visctronic® fan drive achieves best-in-class efficiency in all operating modes by driving the fan either electrically or mechanically.
