摘要： A heat sink includes a base plate and a plurality of cylindrical pins extending upwardly from the base plate. The cylindrical pins each include an upper dissipating portion, a lower mounting portion, and an engaging portion between the dissipating portion and the mounting portion. The mounting portion is interferentially fitted in a lower part of a corresponding aperture of the base plate. The engaging portion has a diameter smaller than that of the mounting portion. The engaging portion is cramped by an interior wall of the base plate defining an upper part of the corresponding aperture of the base plate by punching an upper surface of the base plate downwardly at a rim of the corresponding aperture.

摘要： A heat dissipation device includes a heat sink (10) for contacting a heat-generating component and a fan (20) mounted to the heat sink. The fan includes a frame (22) and a motor (24) received in the frame. The fan has an intake. The frame has a top level and a bottom level. An airflow is generated by the fan and flows through the heat sink. An anti-backflow plate (30) is mounted between the top level and the bottom level of the fan. The anti-backflow plate extends outwardly and beyond an extremity of the heat sink to prevent the airflow flowing through the heat sink from entering the intake of the fan.
