Abstract: 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 (120) 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 abridge (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).

Abstract: A novel heat transfer system is herein proposed involving a coupler which, when attached to a heat sink, defines at least a part of a vapor chamber inside the heat transfer system. The coupler attaches component heat source to the header to a thermally transferring connection with the heat sink.

Abstract: In the method according to the invention, the discrete electric component to be cooled is connected to the cooling element without a circuit board or substrate. In the method, a layer of insulating material is thermally sprayed on one surface of the cooling element. The connection points and conductors required by the discrete electric component are formed on top of this insulating layer. The discrete electric component is glued onto the insulating layer. Subsequently, the electrical connections for the discrete component are made. After the discrete component has been electrically connected, it can still be protected using a layer of thermally sprayed insulating material.
