Abstract
The present disclosure relates to techniques of active cooling of an electronic device. Particularly, it is provided a cooling device comprising a base plate comprising a first main surface extending in a longitudinal direction and comprising a plurality of fins extending from the first main surface in a fin height direction. Each fin has a cross section perpendicular to the fin height direction with a contour defined by two halves of the contour that are symmetric to each other with respect to a symmetry axis perpendicular to the fin height direction, wherein the first half of the two halves of the contour consists of a first round arc region between and extending into a first and a second extension region and the second half of the two halves of the contour consists of a second round arc region between and extending into a third and a fourth extension region.
