摘要： A heat dissipating device includes a base, a heat pipe disposed on the base, and a plurality of first and second heat dissipating fins. Each first heat dissipating fin includes a fin body having a first through hole for extension of the heat pipe therethrough. The first and second heat dissipating fins are mounted on the heat pipe in a stack and in a spaced-apart alternating arrangement. Each second heat dissipating fin includes a fin body having a second through hole for extension of the heat pipe therethrough, two adjacent lateral edges, and a cut edge interconnecting the lateral edges such that each second heat dissipating fin has a smaller area than each first heat dissipating fin. Thus, the flow field resistance of the heat dissipating device can be reduced to increase the amount of airflow through the heat dissipating device for enhancing the heat dissipating efficiency.

摘要： A heat-dissipating device includes a heat sink, a heat-dissipating fan, and a first air guide hood. The heat sink includes a base, and a plurality of interconnected heat-dissipating fins provided on the base. Each adjacent pair of the heat-dissipating fins defines an air channel therebetween. The heat-dissipating fan is disposed at a rear side of the heat sink to provide a heat-dissipating air current to the heat sink such that the air current flows from the rear side of the heat sink through the air channels and out through a front side of the heat sink. The first air guide hood is disposed at one of left and right sides of the heat sink and is located in front of the heat-dissipating fan to guide a portion of the air current provided by the heat-dissipating fan to the outside through one side of the heat sink.
