Aluminum extrusion heatsink is a common radiator in life. Extrusion aluminum heatsink is superior to die-cast aluminum heatsink. The extruded profile is extruded and its inter-molecular gap (lattice gap) has been compressed, resulting in a substantial increase in density. However, the die-casting profile is not extruded, the molecules are relatively loose, and the density is of course less than that of the extruded profile, so the heat dissipation is not as good as that of the extruded profile. The denser the texture of the material, the better its thermal conductivity. The extruded profile is also stronger.
