Fins-type heat sink and method for assembling the same

摘要

In a heat sink and a method for assembling the same, the heat sink includes a base (10), a heat pipe (11), fins (12), a presser (13) and caps (14). The presser (13) is provided with through-holes (130). The periphery of the through-hole (130) is provided with an annular neck (131), so that the distal end of the heat pipe (11) can penetrate the through-hole (130). The periphery of each annular neck (131) is provided with notches (132) on the presser (13). Each cap (14) covers on the annular neck (131), and it extends downwards to form protruding flaps (140). The flap (140) penetrates the notch (132) and is folded outwards to abut the bottom surface of the presser (13). According to the assembling method, via the presser (13) and the caps (14), the fins (12) can be assembled with the heat pipe (11) tightly.
