摘要： A heat-dissipating device and its manufacturing process are provided for significantly increasing the number and size of blades so as to enhance the heat-dissipating performance. The heat-dissipating device has a plurality of blades arranged around the hub of the heat-dissipating device and there is an overlapped region formed between every two adjacent blades. A single mold is used to manufacture such a heat-dissipating device so that not only can the manufacturing cost be reduced but it can significantly increase the number and size of blades so as to increase the heat-dissipating efficiency.
