Stacked fin heat sink are a fin set composed of a series of copper and aluminum flakes (0.2mm~0.6mm) that are stamped into specific shapes and connected together. Usually, the stacked fin heat sink are connected to the heat pipe and copper (aluminum) base plate by welding. The heat is transferred from the heat source to the stacked fin heat sink through the heat pipe or bottom plate, and then dissipated into the air through the stacked fin heat sink.
The characteristics of Stacked fin heat sink are high heat sink efficiency, light weight, small size and low cost. The heat sink efficiency of Buckle fin heat sink is high because its large surface area can fully contact the air, which is beneficial to heat sink. Buckle fin heat sink are lightweight because they are stamped from thin sheets of aluminum or thin copper. The small size of the snap-on fin is due to its thin thickness and small size. The low cost of Buckle fin heat sink is due to its simple manufacturing process and low cost.
Stacked fin heat sink are widely used in electronic equipment, electrical equipment, automobiles and other fields. In electronic equipment, Buckle fin heat sink are mainly used for heat sink, such as computers, mobile phones, TVs, etc. In electrical equipment, stacked fin heat sink are mainly used for heat sink, such as refrigerators, air conditioners, washing machines, etc. In automobiles, Buckle fin heat sink are mainly used for heat sink, such as engines, gearboxes, etc.
