Abstract (en)
[origin: WO2019018867A1] Heat sink (140) for cooling an electronic component of a vehicle headlight, which heat sink (140) has a cooling structure with an external contour which, when considered along an imaginary sectional line, follows a contour curve which can be described by a contour function in at least one section, wherein a basic profile is formed from a first superimposition of a basic function and a fundamental function, and the contour function is formed from a second superimposition of the basic profile and a superimposition function, wherein the first superimposition is carried out in that the function profile of the basic function forms an axis of a curvilinear coordinate system of the superimposition function, and the second superimposition is carried out in that the function profile of the basic function forms an axis of a curvilinear coordinate system of the superimposition function, wherein the basic function has a linear, circular or circular-arc-like profile, and the basic function has a linear or undulating profile, and the superimposition function has an undulating profile.
