A combination heat sink form of a stack of radiation fins is disclosed. Each radiation fin has retaining flanges at two opposite lateral sides for securing another radiation fin. Each retaining flange has a bottom neck perpendicularly extending from the respective radiation fin, two pairs of vertically spaced retaining fingers respectively extending from two opposite lateral sides of the bottom neck in a parallel manner relative to the respective radiation fin for securing another radiation fin, a top retaining notch defined between the two pairs of vertically spaced retaining fingers above the bottom neck for accommodating the bottom neck of another radiation fin, and a retaining gap defined between each two vertically spaced retaining fingers for receiving another radiation fin.
