Abstract
A multiple-stacked marine heat exchanger for cooling at least one heat source in a marine vessel having an upper marine heat exchanger with a forward beveled end and upper coolant flow tubes connected thereto, a lower marine exchanger having a forward beveled end which converges with the forward beveled end of the upper marine heat exchanger and lower coolant flow tubes connected thereto, and an ambient water passageway extending through each pair of stacked marine heat exchangers in the multi-stacked marine heat exchanger. In one situation, the beveled ends cooperate to form a stagnant pressure region near the entrance to the ambient water passageway to create an increase in pressure at the entrance to create jets of turbulent water flowing through the passageway to break up the laminar boundary layer and increase heat transfer from the coolant flow tubes.
