Grooved baffle for a heat exchanger

摘要

The present invention relates to a grooved baffle for heat exchangers, primarily heat exchangers intended for cooling hot gas, for example, gas recirculated in an internal combustion engine or EGR (Exhaust Gas Recirculation) gas, by means of a coolant. In addition to supporting the bundle of heat exchanger tubes, the baffle according to the invention allows modifying coolant flow direction by preventing or significantly limiting the occurrence of recirculation areas or stagnation points in the coolant flow.
