HEATSINK MANUFACTURING METHOD FOR ELECTRONIC AND MECHANIC PARTS USING THERMAL CONDUCTIVITY OF PLASTIC

摘要

A method for manufacturing a heat sink for electronic and mechanical parts using a thermal conductive plastic and a manufactured article are provided to improve heat radiating efficiency and reduce weight of the heat sink. A heat sink includes a body plate(10), and a plurality of ribs formed on the body plate. The ribs include corner ribs(11 to 14) which are protruded from four corners of the body plate and have bolt mounting holes; a block type rib(15) which is protruded eccentrically from a center of the body plate, and has an upper center which is recessed, and bolt mounting holes formed at upper and lower portions of the recessed part; and a stepped rib(16) formed between left and right corner ribs(13,14).
