Fraunhofer Institute for Solar Energy Systems ISE
Wire-based heat exchanger for use as either an evaporator or a condenser.
Fraunhofer ISE investigates the entire range from basic thermodynamic processes of heat transfer to metrological investigations in laboratory and field.
At the fundamental level, we optimize heat exchangers to achieve higher energy efficiency, reduced installation space and mass. Innovative approaches to the use of metallic wire structures as surface enlargement in air-fluid heat exchangers have shown experimentally a significantly increased compactness of up to 50% with the same transmission performance.
A further focus is the targeted identification of structure/material and coating combinations to avoid condensate blocking, the reduction of ice formation and corrosion behavior when used as evaporators.
Our R&D services include:
- Fluid and thermodynamic calculations
- Optimization of the energetic efficiency
- Measurement of the transmission power
- Qualification of coated heat exchangers regarding blocking and ice formation
