Abstract
An exemplary heat sink assembly includes a base plate, a number of fins, a heat spreader and a heat pipe. The fins are mounted on and thermally connect with the base plate for dissipating heat of the base plate. A bottom one of the fins has a body parallel to the base plate and a number of supporting tabs extending downwardly from the body.The supporting tabs engage with a top surface of the base plate to support the fins onto the base plate and reinforce a whole strength of the heat sink assembly. The heat spreader is mounted below the base plate. The heat pipe includes a horizontal evaporating portion sandwiched between the heat spreader and the base plate and a vertical condensing portion extending from a free end of the evaporation portion and passing through the fins.
