HEAT SINK AND ITS PRODUCTION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a heat sink improved in fin structure for responding to the demand for high radiation characteristics. SOLUTION: The heat sink 1 is characterized by that a plate fin parallel body 2 constituted by penetrating an aluminum pipe 22 into a multitude of aluminum made plate fins 21 is soldered to one surface 101 of a steel-made base plate 10 at one edge 211 of each plate fin 21 and constituted.
