Abstract
Abstract An aftercooler in a turbo-charged engine including a removable core having supporting plates at intervals along the length of the core. The periphery of the supporting plates and cooling fins between the plates generally conform to the cross section of the opening of the core supporting housing of the intake manifold. The end walls are sealed to form coolant fluid chambers for fluid flow through fluid passages extending longitudinally through the core while the cooling fins and supporting plates spaced along the length of the intercooler core define cross passages for the flow of the intake air.
