Thermal Energy Converters

Thermal energy converters based on functional materials

Functional materials with special physical properties are a focus of the research performed by the Thermal Energy Converters business unit. We use caloric and thermoelectric materials to build innovative systems for cooling, temperature control and converting heat into electricity. Using these materials in heat pumps, cooling systems and generators makes the systems we develop especially environmentally friendly, cost-efficient and durable. Our work draws on more than 20 years of experience in material synthesis and far-reaching expertise in special measurement techniques, simulation, module construction and system integration.

Our primary goal is the development of efficient and environmentally friendly cooling systems, heat pumps and thermoelectric generators on the basis of innovative functional materials. This work is guided by questions of environmental compatibility, industrial manufacturing, integration into systems and not least availability of raw materials. When it comes to materials development, the focus is always on the specific application in a system – from thermoelectric high-temperature generators to the use of Peltier modules to exploit waste heat for temperature management to environmentally friendly cooling systems that are based on magnetocaloric, electrocaloric and elastocaloric materials and do not require harmful refrigerants.

Electrocaloric heat pumps

In the lighthouse project »ElKaWe«, six Fraunhofer Institutes are working on the development of efficient electrocaloric heat pumps as an alternative to compressor technology.

Surface and Coatings Technology

Editor's Choice

A scientific paper on »Thermophysical properties of coatings in the Ti(B,N) system grown by chemical vapor deposition«, written under the auspices of the Austrian Montanuniversität Leoben and co-authored by Fraunhofer IPM, was selected as Editor’s Choice by the »Surface and Coatings Technology« magazine. For the paper, the Fraunhofer IPM team conducted thermal conductivity measurements using the Time Domain Thermal Reflectance (TDTR) method.
