aluminumskived fin

Folded-fin assemblies from Aavid Thermalloy offer maximum cooling surface in minimum volume. Developed for aerospace and military markets, folded-fin heat sinks have found a strong commercial niche. Available in a wide variety of styles, materials and fin densities, folded fins can be used in forced convention and natural convention cooled systems. Virtually all parts are customized, with very few standard parts available. Features Lightweight cooling fins Reduced material cost Reduced assembled part weight Minimal material thickness Reduced center-to-center fin spacing, allowing more fins per inch of width Fin heights up to 51 mm (2.0") Minimized mounting base thickness Folded-fin stock can be attached to a mechanical heat spreader with thermally conductive epoxy, brazing, welding, or similar metallurgical bonds
