Lancaster, PA May 2, 2018 – Advanced Cooling Technologies, Inc. (ACT) announced today the launch of its new patented Isothermal Card Edge, ICE-Lok™ wedgelocks. ICE-Lok™ is designed to enhance the card-to-chassis, through-the-wedgelock heat conduction by adding more contact surfaces between the card and the chassis. The new wedgelock design offers a 30% reduction in thermal resistance compared to similarly sized COTS wedgelocks. This has enabled reduction of component temperatures of up to 10°C in some 100W card applications. ICE-Lok™ wedgelocks have been thoroughly tested for thermal and mechanical stability with repeated insertion/removal testing. They are designed to meet the dimensional requirements of the VITA specification; and the new friction lock feature ensures that card deformation is avoided.
According to Mr. Jens Weyant, ACT’s Defense/Aerospace Products Group Manager, “For years we have been supplying our military customers with excellent thermal management solutions for both the conduction cooled cards and the chassis frame. With the new ICE-Lok™ wedgelocks we can now offer solutions to all the thermal bottlenecks in ruggedized chassis, ensuring the electronic devices can operate with maximum performance. We’re excited to begin working with customers to deliver the improved thermal performance they’ve been asking us for.”
ACT’s R&D and Product Development engineers have been developing the ICE-Lok™ for several years, working with the military and their suppliers to address the critical thermal and mechanical requirements. The ICE-Lok™ is a wedge-type card retainer, but with the wedge faces cut at compound angles. When actuated, this allows the wedges to move with two degrees of freedom, expanding the card retainer in two, rather than one, directions. The ICE-Lok™ also uses “L” shaped wedges to make a direct thermal connection between the card and chassis, significantly increasing the contact area between the card, clamp, and chassis. This approach bypasses the significant wedge-to-wedge thermal resistance in a conventional wedgelock and contacts four faces rather than two as with a conventional wedgelock. ICE-Lok™ can be seamlessly integrated into standard VITA systems, creating longer life and higher reliability for a system’s critical components without costly board or chassis redesign.
