| Summary: | The invention relates to heat sinks made of finned aluminum extrudates and useful for electronic devices and information devices having an electronic device incorporated therein. The heat sink of the invention made of a finned aluminum extrudate comprises a base plate, and fins arranged in parallel and provided on one surface thereof. The base plate is 25 to 400 mm in width, 25 to 400 mm in length and 2 to 5 mm in thickness, and the fins are 1 to 30 mm in height, 1 to 1.9 mm in interval and 0.1 to 0.8 mm in thickness. The thickness of the fins is reduced within a predetermined range according to the invention to thereby ensure diminished resistance to the flow of air and improved radiation performance. This also renders the heat sink lightweight, serving to reduce the size and weight of electronic devices and information devices. |
