Abstract
The restraint systems presently used with existing heat exchangers or recuperators have a thermal growth rate different than the thermal growth rate of the core of the recuperator. The present thermally balanced restraint system overcomes the problem of a different growth rates by utilizing tie rods which are individually made of a plurality of small diameter rods has a thermal growth rate very near that of the core of the heat exchanger. As the plates of the core thermally expand and contract in response to the heat from the engine exhaust, the plurality of small diameter rods also expand and contract at a rate very near that of the core.
