The main indicators for evaluating a pure aluminum radiator are the thickness of the radiator bottom and the current pin fin ratio. It is one of the main standards to test the advantages and disadvantages of aluminum extrusion technology.
Pin refers to the height of the fin of the heat sink,
Fin refers to the distance between two adjacent fins.
Pin fin ratio is the height of pin (not including base thickness) divided by fin, the greater the pin fin ratio is means the greater the effective heat dissipation area of the radiator is. The higher the value, the more advanced the aluminum extrusion technology. At present, the highest value of this ratio of pure aluminum radiator is 20. Generally, if this ratio reaches 15~17, and the quality of the radiator is very good. If the pin fin ratio is higher than 18, it indicates that the radiator is a high-end product.
