Abstract: An air-to-air aftercooler may include a tube configured to direct a flow of charged air. The tube may include at least one first protrusion located on a first interior surface of the tube, and a first longitudinal plane may extend through the at least one first protrusion. The tube may also include at least one second protrusion located on a second interior surface of the tube, and a second longitudinal plane may extend through the at least one second protrusion. Furthermore, the first longitudinal plane and the second longitudinal plane may intersect.

Abstract: A pump includes an impeller with impeller blades that extend radially outward. The pump may further include a pump housing that may surround a radial perimeter of the impeller. Furthermore, the pump housing may include an inlet opening in fluid communication with the impeller and a discharge channel. The pump may further include a heat exchanger supported within the pump housing between the inlet opening and at least one connection port. of the pump housing. The heat exchanger may include one or more tubing coils that extend around an axis.
