Dana develops new heat exchanger for electric vehicles

Dana Holding, a US-based supplier of axle, driveshaft and thermal products for vehicle manufacturers, has developed Long heat exchanger designed to extend battery life in hybrid and electric vehicles.

The company said the heat exchanger has recently debuted on Tesla Motors's 2010 all-electric Roadster Sport car. The heat-exchange technology cools the Roadster's battery by transferring heat generated within the battery to the vehicle's climate-control system.
In addition, a temperature sensor mount provides continuous feedback to the climate-control system. The interface reportedly helps to maintain the battery's ideal temperature during operation, thus helping to extend battery life.
Dana engineers have constructed the heat exchanger using a patented aluminum brazing process, ensuring cleanliness of both the climate control and battery coolant fluids. Dana is manufacturing the heat exchanger at its advanced engineering center at Oakville in Ontario, Canada.
Jim Sweetnam, president and CEO of Dana, said: "Dana is committed to providing our best-in-class engineering and manufacturing expertise to electric-vehicle manufacturers such as Tesla Motors. Our advanced battery technology solutions will help drive our growth in this exciting market segment."
