Dana Puts Aluminum To Use For Hybrid And EV Cooling

Cooling of the battery, components and powertrain is a major issue for hybrid and electric vehicles and part of the range limitations lie with this critical aspect.

Dana Holding Corporation announced this week the introduction of a new aluminum cooling technology aimed at these electric and hybrid vehicles cooling issues.

Specifically, the company said it is utilizing the efficiency of aluminum in its Long brand of integrated cooling plates that enhance heat transfer of insulated gate bipolar transistor (IGBT) switches.

Dana added this technology provides customers with optimized, compact cooling components to address the high-heat, high-power demands of electric and hybrid vehicles.

This technology has been developed to limit the maximum temperature of the IGBT junction in a compact design, providing customers with a clean, lightweight, recyclable, and cost-effective solution that offers superior heat transfer and cooling abilities, stated Dana.

By utilizing the company’s fluxless brazing process, Dana explained it is able to produce cooling solutions that are exceptionally clean and flux-free, minimizing coolant contamination to maintain low conductivity in the power electronics cooling circuit.

In short, Dana’s IGBT cooling solutions are said to improve the ability of automotive electronics engineers to transfer high power between batteries and motors.

“Both OEMs and suppliers are constantly looking at different materials and technologies in order to meet the ever changing needs of the automotive industry,” said Dwayne Matthews, president of Dana’s Power Technologies Group. “By utilizing aluminum cooling solutions we are able to better reach the efficiencies our customers desire, while addressing issues associated with space and weight.”

The IGBT cooling plates will be manufactured at Dana’s facility in Cambridge, Ontario, Canada with production expected to begin in early 2015.

Dana did not mention which manufacturer will use this technology, but it is well known Toyota has a vehicle manufacturing plant in Cambridge, Ontario, building the Rav4 and Corolla.
