Abstract
The invention relates to a heat sink () for cooling a heat source, the heat sink comprising a heat distributor () comprising a 3-dimensional body with a side wall () arranged around a main axis (), and a plurality of plates () coupled to and extending from the side wall, each of the plurality of plates being curved in a cross section perpendicular to the main axis, wherein the plates are twisted along the main axis () of the heat distributor. The present invention solves the excessive fin length issue that is needed for higher values of the external diameter vs. the internal diameter of the fins section. The fins have curvature in all directions, which is referred to as double curvature. This double curvature is the result of two curving of each fin in a radial direction and twisting of the fins along the axial direction.
