A heat dissipating apparatus for dissipating heat generated by heat producing device, includes a base, a fin set and an axial fan. The base is secured on the heat producing device. The fin set comprises a plurality of fins arranged on the base; the fins are spaced apart from and oriented parallel to each other, and form a plurality of air passages therebetween. The axial fan is installed at a lateral side of the fin set and directs airflow into the fin set through the air passages. The fin set has an inclined area at an end thereof, and the fan is installed on the inclined area of the fin set and oblique to the base.
