Abstract
The present invention relates a method of manufacturing a high fin density heat sink comprising the steps of: aligning a plurality of length sections side by side in a mutual parallel arrangement, said length sections having a cross-section comprising a first end portion, a second end portion and a web portion connecting said first and second end portions, said first and second end portions having a width wider then the width of the web portion; clamping the parallelly arranged length sections together, such that said first and second end portions of adjacent parallel length sections are abutting against each other; and bonding the length sections together by applying at least one friction stir welding (FSW) seam across the end portions of the parallelly arranged length sections.
