Abstract
A heat sink for semiconductor components has a fin base and a plurality of spaced fins that all have the same height. A side of the base facing the fins is configured convexly with respect to the side of the fin base facing the semiconductor component, so that when the heat sink is used as intended, the roots of its fins are arranged on a surface of constant temperature. This yields a finned heat sink that attains a heat flux density hitherto achievable only with evaporative or fluid coolers.
