Heatsinks and vehicle headlamps

摘要

heatsink (100, 110, 120, 130,140, 150) for cooling an electronic component of a vehicle headlamp (10),wherein the heat sink (100, 110, 120, 130,140, 150) has a cooling structure having a base (103, 123, 153, 203, 213, 223),on which at least two ribs (101, 111, 121, 131, 141) are arranged, having an outer contour which, when viewed horizontally along an imaginary cutting plane extending to the base (103, 123, 153, 203, 213, 223) follows a contour curve which can be described in at least one section by a contour function (350, 351, 352, 353), wherein the heat sink (100, 110, 120, 130, 140, 150),characterized in that a first superimposition of a basic function (300, 301,302, 303) and a basic function (310, 311, 312, 313) form a basic course, and a second superimposition of the basic course and an superimposition function (330, 331, 332,333) the contour function (350, 351, 352, 353) is formed, wherein the first overlay is made by the functional course of the basic function (300, 301,302, 303) forming an axis of a curvilinear, preferably orthogonal coordinate system of the basic function (310, 311, 312, 313), and the second overlay is made, by the functional course of the basic function (310, 311, 312, 313) forming an axis of a curvilinear, preferably orthogonal coordinate system of the superposition function (330, 331, 332, 333), wherein the basic function (300, 301,302, 303) has a linear course, and the basic function (310, 311, 312, 313) has a linear course,and the overlay function (330, 331, 332, 333) has a triangular gradient.
