A heat sink () for cooling an electronic component of a vehicle headlamp, which has a cooling structure with an outer contour, which, as viewed along an imagined sectional plane, follows a contour curve, which can be described in at least one section by means of a contour function, wherein a fundamental course is formed from a first superposition of a base function and a fundamental function, and the contour function is formed from a second superposition of the fundamental course and a superposition function, wherein the first superposition takes place in that the functional course of the base function forms an axis of a curved coordinate system of the fundamental function, and the second superposition takes place in that the functional course of the fundamental function forms an axis of a curved coordinate system of the superposition function, wherein the base function has a straight, circular or arc-like course, and the fundamental function has a straight or wave-like course, and the superposition function has a wave-like course.
