Aluminum Casting Heat Sink

Although the price of aluminum extruded heat sink is low, the manufacturing cost is also low, but it is limited by the soft texture of the aluminum itself. The ratio of the thickness of the fin to the height of the fin generally does not exceed 1:18, so each PC manufacturers continue to increase the heat dissipation area, while the heat dissipation space remains unchanged, the manufacturers proposed a more suitable solution, encrypting the fins, thereby increasing the number of fins; bending the fins, thereby increasing the heat dissipation Area; heating the aluminum ingot from solid to liquid through the mold, and then cooling it becomes the heat sink we want.
