An improved heat sink including a plurality of radiating fins constructed therefrom. Two opposite edges of the radiating fins are respectively folded upwards at right angles to the face of the radiating fins. Air vents are defined at applicable distances on the folded edges thereof. On another face of the radiating fins, and distanced relative to the aforementioned air vents on the folded edges, are attached a plurality of protruding pieces affixed at right angles to the face of the radiating fins. A convex protrusion is additionally configured on each of the protruding edges. The convex protrusions reciprocally engage with the air vents of the folded edges, and a string of radiating fins reciprocally engage to form a heat sink in its entirety thereof.
