  • Patent number: 11493002
    Abstract: An exhaust gas recirculation (EGR) cooler for mounting to a coolant collector bracket may include a cooler body having a top, a bottom, a length extending in a longitudinal direction, and a width extending in a lateral direction perpendicular to the longitudinal direction, and at least one mount coupled to the bottom of the cooler body. An interior of the mount may be in fluid communication with an interior of the cooler body. A width of the at least one mount in the lateral direction of the cooler body may be equal to or less than the width of the cooler body. The at least one mount may be positioned such that the mount does not extend beyond the width of the cooler body.
