Abstract
A high-efficiency heat sink includes a base and a plurality of heat sink fins A folded portion of each heat sink fin is formed by folding after being pressed and thinned, so that the thickness of the folded portion is less than the thickness of an insertion end of each heat sink fin. The thickness of the portion where the heat sink fin is inserted into a groove of the base is less than twice the thickness of the heat sink fin. It is beneficial to reduce the distance between two adjacent heat sink fins on the base, so that the heat sink fins can be arranged more densely, thereby improving the heat dissipation effect of the entire heat sink effectively.
Claims8
A high-efficiency heat sink, comprising a base and a plurality of heat sink fins, a surface of the base being formed with a plurality of spaced grooves for attachment of the heat sink fins, each of the heat sink fins having an insertion end, the insertion end being reversely folded and extending to form a folded portion, the folded portion being formed by folding after being pressed and thinned, the folded portion having a thickness less than that of the insertion end, the folded portion and the insertion end being fitted and embedded into a corresponding one of the grooves of the base;
- wherein after the folded portion of each heat sink fin is inserted into the corresponding groove of the base, a press head is aligned with the folded portion for pressing, the press head covers the folded portion, after pressing, the folded portion is pressed down in the corresponding groove to be deformed, expanded and coupled into the corresponding groove so that the heat sink fins are combined with the base.
