Abstract

A heat sink for an arc lamp comprises a thin-wall copper strip that is brazed in pleated folds between inner and outer cylindrical rings to create cooling fins. The thickness of the material used for the cooling fins can therefore be exceedingly thin, e.g., 0.012 inches. The cylindrical rings act as fin supports and provide mechanical sturdiness. The thinness of the fin material allows a large number of fins to be included and the efficiency is increased thereby.
