Stacked fin heat sink is made by using a high pressure to pressing special structure single profile, multiple profiles together into a complete heat sink. Stacked fin (also know as bonded fin or folded fin)  heat sinks are manufactured by stamping sheets of rolled aluminum or copper into a tightly formed array of fins. The character is neat on a metal plate with multiple parallel intervals are arranged on the convex groove and the groove, and the groove under each convex slot on the top and bottom of each one vertical bending forming one cant, cant make the groove under a heat sink in a heat sink on convex slot cant agree with each other, so that the multiple heat sink stacked together to form a heat dissipation module. With large heat dissipation area and simple assembly, convenient and fast. Stacked fin solutions offer better performance when compared to typical extrusion heat sink, due to thinner fin profiles leading to higher surface area and lower pressure drop. The stacked fin heat sink is often used in machines that need heat dissipation from both sides. From the appearance, both sides are cooling base plate, the heat sink fins in the middle, heat from both sides through cooling base plate to the central fins for heat dissipation.
