Abstract
An apparatus for transferring heat from a heat source to air, comprising a heat sink with a plurality of fins. A fin of the plurality of fins is configured as follows: the fin comprises a conduit arrangement for a heat-carrying fluid; in a boiling region of the fin, the conduit arrangement comprises a vapour guiding path; and in the boiling region, the conduit arrangement comprises one or more boiling chambers. Each of the one or more boiling chambers has an outer boundary. The respective boiling chamber is located within a chamber region defined by an imaginary quadrilateral having four sides and four vertices. By means of the arrangement and configuration of the boiling chambers and/or of the vapour guiding path, the heat transfer efficiency of the fin is improved.
