A heat dissipater structure has a heat sink base with peripheral sides thereof folded upwards from the bottom plate and cut into a plurality of lateral plates at proper angles to form wind channels for current conduction and to define a receiving slot at the center for holding a fan. A convex block is disposed on two opposite lateral plates for easily hooking and assembling a cover body so as to allow the air current inducted by the fan to rapidly dissipate the heat absorbed by the bottom plate outwardly through the wind channels formed by the interference of the lateral plates.

1. An improved heat dissipater structure comprising: a heat sink base comprising a flat base plate; a periphery of the base plate forming a plurality of fins extending upward, each fin is a flat vertical plate angled corresponding to a rotational direction of a fan as to provide airflow channels with adjacent fins; the flat base plate and the fins define a receiving cavity, the fan is disposed inside of the receiving cavity; a pair of hook-like blocks extending upward on opposite sides of the periphery of the flat base plate; a cover body having a central opening for air inlet, the cover body disposed on top of the base plate and the fan; a pair of upper retaining hooks extending downward in correspondence with the pair of the hook-like blocks and engaging with the hook-like blocks to retain the base plate, the fan and the cover body together; and a pair of stop blocks located on opposite sides of the cover body, extending downward from the cover body and pressed against the base plate.
