IMPROVED HEAT EXCHANGER

摘要

A keel cooler (200) having a beveled bottom wall (216)) with orifices (220) on the inner wall of the exterior tubes (208) extending into the header (204), the orifices (220) being in the natural flow path of coolant flow. The orifices (220) are sufficiently large so as not to restrict the flow of coolant. The anode assemblies (222) and drain plugs (224) are mounted on the beveled bottom wall (216).
