Exemplary embodiments of the present disclosure are directed to an apparatus including pipes having internal longitudinal walls dividing the pipes into channels, a first and a second connecting part for providing a flow path between the channels of the pipes, a first heat transfer element having a first base plate with a first surface for receiving a heat load from one or more electric components and for transferring the heat load to a fluid, and a second heat transfer element. In order to obtain an efficient apparatus at least one first pipe that is at a location of an electric component is at least partly embedded in the first base plate via a second surface of the first base plate, while the pipes which are not at the location of an electric component are not embedded in the first base plate.
