According to an example aspect of the present invention, there is provided a heat sink (100) with an elongated inner core (110) and an elongated outer profile (120). The profile forms a cross-sectional periphery and is provided around and at a distance from the core (110) such that an intermediate volume (160) is formed between the core (110) and the profile (120). The heat sink (100) also has a bridge (130) connecting the profile (120) to the core (110). The profile (120) has at least one opening (140) exposing the intermediate volume (160) to the ambient. The at least one opening (140) extends in a direction which is non-parallel to the dimension of elongation of the inner core (110).
