  • Cooler for exhaust gas recirculation
    Patent number: 10934978
    Abstract: A cooler for exhaust gas recirculation is arranged to absorb thermal deformation of a tube by having a modified header structure without additional parts. The cooler for exhaust gas recirculation is applied to an exhaust gas recirculation device. The cooler includes: a body disposed between a pair of flanges connected to an exhaust gas recirculation line; a tube accommodated in the body and having both ends respectively coupled to the flanges through headers such that exhaust gas flows therethrough; and cooling fins accommodated in the body to exchange heat with exhaust gas flowing through the tube, in which the headers are deformed in correspondence to deformation of the tube by expansion and contraction thereof.
