Note:
An overview is given of recent high temperature heat exchangers technology developments, both in the thermo-fluid dynamic innovative solutions and in the materials. Gas turbine recuperative cycles, microturbine systems and indirectly fired cycles are the investigated fields where this kind of heat exchangers in used. Some common technological features join all of them, namely: new surface geometry design and burdensome material requirements. The most important difficulties arising from the specific conditions of each heat exchange system are pointed out, together with their possible solutions. A comparison among them is presented and some suggestions are proposed about expanding the boundaries of the individual research fields, to get a wider understanding of common critical issues. Finally, the paper focuses on the main current challenges to be faced in the near future in order to get a competitive development of such systems.
