Abstract:
A gas-to-gas heat exchanger for exchanging heat between an exhaust gas and a charge gas comprising:a plurality of exhaust gas plates, each exhaust gas plate having a plurality of raised contoured ridges forming a substantially sinusoidal path along each exhaust gas plate and defining multiple substantially sinusoidal exhaust gas channels for directing the exhaust gas therealong; a plurality of charge gas plates stacked alternately with and parallel to the exhaust gas plates, each charge gas plate having a plurality of raised contoured ridges adjacent to the exhaust gas plates and forming a substantially sinusoidal path along each charge gas plate and defining multiple substantially sinusoidal charge gas channels for directing the charge gas therealong; wherein the exhaust gas plates and the charge gas plates are connected together to permit exhaust gas entering the exhaust gas contoured channels to flow parallel to and in a substantially opposite direction to the charge gas flowing in the charge gas contoured channels to facilitate heat transfer from the exhaust gas to the charge gas.
