Abstract
A heat dissipating device includes a base and a plurality of heat dissipating fins. Each of the heat dissipating fins includes a heat dissipating portion, a fixing portion and an overflow-proof structure. The fixing portion is fixed in the base. The overflow-proof structure is connected between the heat dissipating portion and the fixing portion. A width of the overflow-proof structure is larger than a width of the heat dissipating portion and larger than a width of the fixing portion.
Claims23

A method of manufacturing a heat dissipating device comprising:
- forming a plurality of heat dissipating fins by a forming process, wherein each of the heat dissipating fins comprises a heat dissipating portion, a fixing portion and an overflow-proof structure, the overflow-proof structure is connected between the heat dissipating portion and the fixing portion, a width of the overflow-proof structure is larger than a width of the heat dissipating portion;
- putting the fixing portion of each of the heat dissipating fins into a mold;
- pouring a melt metal material into the mold;
- and
- processing the melt metal material by a die casting process so as to form a base, wherein the base covers the fixing portion of each of the heat dissipating fins and the overflow-proof structure of each of the heat dissipating fins prevents the melt metal material from overflowing.
