Within the scope of the research project, new types of heat exchangers from additive manufacturing are to be developed up to an operating temperature of 900°C. The heat exchangers are to be used in a wide range of applications. An important aspect is the operational safety in the form of a long service life as well as corresponding gas tightness between the channels, so that they can also be considered for the use of flammable and hazardous media. Furthermore, the heat exchangers should have a high power density and a low pressure drop due to geometries adapted to the flow. For this purpose, extensive numerical calculations of the strength as well as the heat transfer are carried out. The developed structures will then be manufactured by selective laser melting and investigated experimentally in a high-temperature test rig prepared for this purpose. On the basis of the experimental investigation, correlations are derived for rapid calculation of the heat transfer coefficients and the pressure loss coefficients. These correlations can then be used to quickly design and directly manufacture heat exchangers to meet specific requirements.
Project Promotion
The project is funded by the ZIM program (Central Innovation Program for SMEs) of the German Federal Ministry of Economics. The project sponsor is AiF GmbH.
