Dana claims industry’s first battery cooling tech for electric vehicles
Maumee, Ohio — Dana Holding Corp. has developed a Long heat exchanger designed to extend battery life in hybrid and electric vehicles. The technology recently debuted on Tesla Motors’ 2010 all-electric Roadster Sport.
Dana said the unique heat-exchange technology cools the Roadster’s battery by transferring heat generated within the lithium-ion battery to the vehicle’s climate-control system, while a temperature sensor mount provides continuous feedback to the climate-control system. This interface helps to maintain the battery’s ideal temperature during operation, thus helping to extend battery life, said the company.
Dana engineers constructed the heat exchanger using a patented aluminum brazing process to ensure the cleanliness of both the climate control and battery coolant fluids. The use of high-strength aluminum alloys provides greater material strength and contributes to weight saving, while the chiller’s compact design provides significant space savings, said the company.
Dana is manufacturing the heat exchanger at its advanced engineering center in Oakville, Ontario, Canada.
Touch user interfaces have made significant advances in the consumer electronics market particularly for mobile phones and notebook computers, opening the door for adoption in other applications including white goods, computer peripherals, medical equipment, and instrumentation. Synaptics made its debut in the home appliance market earlier this year with the launch of the Samsung Hauzen ZERO air conditioner.
Smaller distributors were the only ones to post sales gains in 2009. Interestingly, two of the five distributors that posted growth last year -- Interstate Connecting Components and Sherburn Electronics -- derive 100 percent of their sales from interconnect products. Both of them also target the military/aerospace industry. Here are the top 10 sales leaders by ICs, passives/electromechanical devices, interconnects and computer products as well as sales growth.
