Abstract

A heat sink comprises a base 20, e.g. of copper, with inclined sides on which are mounted a heat-dissipating section 10, e.g. of aluminium, with fins 11 formed by skiving. The heat sink may be used in conjunction with a fan 30. In an alternative embodiment (Fig 7A) the base may be omitted.
