Patent abstract

A heat exchanger has a shell and tube stack disposed within a shell inner chamber. A coolant chamber extends from a shell end, accommodates a portion of the tube stack, and has a sidewall that extends outwardly from the tube stack. A divider is disposed within the coolant chamber between the sidewall and tube stack, and extends axially along the chamber to the end of the shell splitting the coolant chamber into inlet and outlet coolant passages. For example, a pair of dividers are disposed within the coolant chamber and are attached to a respective sidewall surfaces. A coolant inlet and outlet is in fluid flow communication with respective inlet and outlet coolant passages. A cooling medium within the heat exchanger flows longitudinally within the inlet coolant passage along the tube stack in a direction opposite from the coolant flow path within the outlet coolant passage.
