Abstract

A thermal screen for use with an exhaust gas recirculation system. The thermal screen is configured to direct the flow of exhaust gases that pass through an exhaust gas recirculation valve toward the tubes of an exhaust gas recirculation cooler. Moreover, the thermal screen is configured to direct the flow of exhaust gases through openings in a header of the exhaust gas recirculation cooler so as to reduce and/or prevent a front surface of the header from being directly exposed to the passing exhaust gases and the heat entrained in those gases. By minimizing and/or preventing the front surface from direct exposure to the exhaust gases, the thermal screen may reduce the thermal strain on the header that is typically associated with differences in temperatures between the front and back surfaces of the header.
