A housing;
A support member disposed within the housing and defining a passage therewith;
It has two opposite end portions and two opposite side portions, and is folded itself so that the side portions are close to each other, the side portions are fixed to the support member, and the end portions are sealed. A plurality of heat conducting cells each including a sheet of corrugated material adapted to form a chamber and secured to the support member;
An inlet header;
A plurality of inlets formed in the support member, each in fluid communication with the inlet header and the chamber;
An exit header;
A plurality of outlets formed in the support member, each in fluid communication with the outlet header and the chamber;
A recuperator for a turbine comprising a combination of The turbine recuperator of claim 1, wherein the chamber forms a cold cell through which preheated air passes. The recuperator for a turbine according to claim 1, wherein the housing has a cylindrical cross section. The turbine recuperator according to claim 3, wherein the support member has a cylindrical cross section and extends coaxially with respect to the housing. A cylindrical housing;
A cylindrical support member disposed coaxially within the housing and forming an annular passage between the housing and the passage of hot exhaust air;
It has two opposite end portions and two opposite side portions, and is folded itself so that the side portions are close to each other, the side portions are fixed to the support member, and the end portions are sealed. A plurality of heat conducting cells each including a sheet of corrugated material adapted to form a chamber and secured to the support member;
An inlet header;
