Aluminum profile heatsink is currently the most common type of profile heatsink. In order to increase the heat dissipation area of its fins, the most common processing method for pure aluminum profile heatsinks is aluminum extrusion technology. The main indicator is the thickness of the heat sink base and the pin-fin ratio. Pin refers to the height of the fins of the heat sink, and fin refers to the distance between two adjacent fins. The pin-fin ratio is the height of the pin (excluding the thickness of the base) divided by fin. The larger the pin-fin ratio means the larger the effective heat dissipation area of the heat sink, which means that the aluminum extrusion technology is more advanced.
