HEAT SINK AND HEAT DISSIPATION SYSTEM FOR LIGHTING MODULE

摘要

A heat sink (10) comprising a body (12) having a plurality of parallel fins (16) for dissipation of heat. A central chamber (30) is provided extending through the body (12) and a plurality of channels (36) are provided in the body portion (12). Each channel (36) extends from the central chamber (30) to a space between a pair of adjacent fins (16) such that compressed air delivered to the central chamber (30) flows outwardly through the channels (36) between adjacent fins (16) to draw heat away from the fins (16).
