Abstract
The heat sink includes a base (3) supporting a structure of parallel fins made of aluminium. The base is attached to the component to be cooled. The base is made up of copper elongated profiles which are assembled using square shaped protrusions (6) and recesses (7). Similar protrusions and recesses are provided on the aluminium fins. The fins are assembled using the same method and then fixed on the base.
