Open-pore metal foams offer greater heat transfer
A liquid or gas circulates within many heating technology components to provide a heat transfer medium. In contrast to the meandering tube bundles or fins previously usually deployed in the components, open-pore metal foams have the advantage that they have a greater surface. This facilitates the transfer of large amounts of heat.
The metal foams can be made with cell widths between 0.3 and 5 mm. The production begins with open-cell polyurethane foams. These are cast in a liquid ceramic suspension. The plastic inside is then burnt by heating. The resulting mould can be filled with various metal alloys using precision casting or powder metallurgical processes.
Open-pore metal foams can be used, for example, in car radiators, high-performance evaporators and latent heat storage systems. The Fraunhofer Institute for Manufacturing Technology and Advanced Materials in Dresden is carrying out the research in collaboration with industrial partners.
