An exhaust gas recirculation (EGR) cooling system includes a valve (14) and a cooler (12). A motor (28) opens the valve allowing hot fluid exhaust gas to flow into the valve. Cooling fluid continuously flows in and circulated around the valve (14), reducing the amount of heat transfer from the hot fluid to the valve components. The hot fluid travels through a plurality of tubes (20) in the cooler, continuing to transfer heat to the cooling fluid. As the hot fluid is cooled, the unburned gas in the hot fluid is recycled to be burned by the engine.
L'invention concerne un système intégré de refroidissement RGE comprenant une soupape (14) et un refroidisseur (12). Un moteur (28) ouvre la soupape, permettant ainsi l'écoulement des gaz d'échappement chauds dans la soupape. Le liquide de refroidissement s'écoule en continu dans la soupape (14) et autour d'elle, réduisant la quantité de transfert de chaleur depuis le fluide chaud vers les éléments de soupape. Le fluide chaud traverse une pluralité de tubes (20) dans le refroidisseur, entretenant le processus de transfert de chaleur vers le liquide de refroidissement. A mesure que le fluide chaud est refroidi, les gaz non brûlés dans le fluide chaud sont recyclés afin d'être brûlés par le moteur.
