In applications where the level of heat generated by the equipment is greater than what can be dissipated using traditional air cooling techniques, the equipment developers are increasingly utilizing cold plates. Cold plates are constructed of copper or other materials that have a high thermal conductivity. Channels are created within the plate by gun-drilling or press fitting copper channels into the plate. Fittings are brazed, bonded or welded onto the plate so that coolant can be run through the channels. The assembly is usually plated with tin for a low-maintenance finish. The entire assembly is often machined prior to plating to ensure a flat surface.
