MACRO-CHANNEL WATER-COOLED HEAT-SINK FOR DIODE-LASER BARS

摘要

A water-cooled heat-sink (20) for a diode-laser bar includes a copper- cooling-unit (22) having an integral mount (24) thereon for the diode- laser bar (). The copper-cooling-unit is attached to a steel base-unit (28). The base-unit and the cooling-unit are cooperatively configured such that at least one cooling-channel is formed in the cooling-unit by the attachment of the base-unit to the cooling-unit. The cooling- channel is positioned to cool the mount (24) when cooling-water flows through the cooling-channel. Fins (34) are provided to guide the cooling water in the slots (42).
