HEAT DISSIPATION DEVICE HAVING FAN HOLDER FOR ATTACHMENT OF A FAN

摘要

A heat dissipation device includes a heat sink, a fan and a holding frame securing the fan onto the heat sink. The holding frame is mounted on a top of the heat sink and has four beams located around the top of the heat sink and defines an opening in a central part thereof corresponding to the heat sink. The holding frame has two air-guiding plates extending inwardly and downwardly from two inner edges of two opposite beams to two opposite lateral sides of the heat sink. The fan is mounted on the holding frame and covers the opening and the two air-guiding plates of the holding frame.
