SINOPSIS

Enhanced heat transfer and process intensification often involves non-trivial devices to be manufactured with complex geometries. Pinned surfaces and micro heat exchangers are two such configurations that come to mind and which are the subject of this paper. The designs of the devices have to conform to the restrictions imposed by the manufacturing technique. Pinned surfaces, for example, can be machined or cast, while microchannel heat exchangers might be manufactured by micro machining or chemical etching. The purpose of this paper is to introduce a relatively new manufacturing technique, Selective Laser Melting (SLM), and to illustrate its potential for developing new designs of heat transfer devices by considering a complex finned surface and a micro heat exchanger. Complex fin-like structures have been built directly onto the surface of a heat sink and micro cross-flow heat exchangers have been manufactured with core dimensions of 10× 10×10 mm. Although the manufacturing technique is still in the development stage and the heat transfer devices that have so far been manufactured are non-optimal, the potential for creative new designs and applications is clear.
