TITANIUM COOLING COILS FOR SURFACE SHIP APPLICATIONS

High machinery space temperatures and generally inadequate ventilation air cooling in many Navy ship machinery compartments influenced a David Taylor Research Center (DTRC) decision to reevaluate seawater cooling coils as a principal means of compartment cooling. Earlier Navy-designed and fabricated copper- nickel seawater coils had suffered numerous reliability problems due to fouling, corrosion, and erosion and were therefore removed from ship use. Advanced plate-fin and integral fin cooling coil designs were evaluated as a means of improving reliability and thermal performance of the previous Navy seawater cooling coils. Math models were developed to analyze the effects on thermal performance of (1) seawater and air temperature, (2) seawater and air flow rates, and (3) coil material. Unique fabrication techniques were assessed for both coils to allow fabrication using titanium in place of copper- nickel for all seawater-wetted components. Finally, various cooling coil waterbox designs were evaluated to improve the seawater flow patterns and thus reduce fouling and increase component reliability.
