Extruded Heat Sinks
The aluminium extrusion process allows to make innumerable shapes profiles. By modifying the shape of the profile, the surface in contact with air changes and consequently the dissipation capability does. The extruded heat sinks are generally used in medium electric power systems both in natural and forced convection.
The extruded heat sinks are presented divided by shape (E, L, H, T, U, P flat back and PC flat back with cover), width and height, and shown in increasing order of size. For example, P400 40 indicates an extruded heat sink having a flat back shape (P), 400 mm wide and 40 mm high.
