Abstract

A heat exchanger for preheating the combustion air of a micro-turbine in a cogeneration system is disclosed. The structure of this heat exchanger includes an assembly of flat distribution frames and spacer metal sheets. Each distribution frame is defined by an outline framing a fluid zone and is equipped with inlet orifices and outlet orifices for the passage of this fluid. The metal sheets are supported by support projections at the distribution frames, which simplifies the manufacture of the heat exchanger.
