Compact and Efficient Cooling Coils for Naval Systems

More compact, lightweight and efficient cooling coils are needed to address increased heat management needs on Navy ships. Under a Phase I effort, Altex has tested and shown the feasibility of an advanced cooling coil concept that can achieve the required cooling at half the typical cooling water flow, and at face velocities above 1000fpm without condensate carryover. Importantly, this good performance is achieved at 70% less volume and 72% less weight than current Navy cooling coils, as well as at a lower cost. Given the good results to date, a Phase II effort is proposed to develop and manufacture prototype versions of the concept and test them at two scales over a range of design and operating conditions to prove the performance under simulated field conditions. In addition, analysis and test data will be used to demonstrate the scalability of the design. Following success with these efforts, the design will be refined to a preproduction level and the cooling coil tested in the field on a ship under operational conditions. These activities will ready the concept for commercialization and deployment under subsequent efforts.
