A microchannel exhaust gas recirculation (EGR) cooler is a compact engine component designed to cool exhaust gases before they are recirculated back into the engine's intake system. It contributes to reducing nitrogen oxide (NOx) emissions and improving engine efficiency by lowering the temperature of the recirculated exhaust gas. The microchannel design incorporates numerous small, parallel channels to maximize heat transfer while minimizing overall size and weight.
