Laptop blade

The utility model discloses a notebook computer blade which comprises an installation base, a plurality of heat dissipation blades distributed at equal intervals are arranged on the side walls of the periphery of the installation base respectively, and a plurality of flow guide grooves continuously distributed at equal intervals are formed in the bottoms of the heat dissipation blades respectively. According to the notebook computer blade, the continuous flow guide grooves are formed in the lower edge of the windward side of the heat dissipation blade, the bionic technology of simulating bird wings is utilized, noise caused in the rotating process of the heat dissipation blade is greatly reduced, and therefore the performance of the notebook computer blade is improved, and the noise is reduced. Comprising a lower mold plate, a casting mold plate is arranged above the lower mold plate, when computer blades are produced, computer blade raw materials are injected into a mold cavity above a column mold plate, an
