Résumé

The focus of this paper is on the recuperative heat exchanger, which uses chemically etched copper plates interleaved with stainless steel axial conduction barriers. A model of the recuperative heat exchanger is described; the model is used to optimize the geometry subject to constraints associated with fabrication and mass. A sub-scale module has been fabricated in order to verify the model and develop the fabrication techniques. The experimentally measured ineffectiveness of the sub-scale module agrees with the model predictions. Based on the success of the sub-scale module and using the verified heat exchanger model, two full-scale modules have been fabricated, assembled and tested at the component level. The performance of the full-scale modules is compared with the model prediction.
