Shell and tube heat exchanger for ships LHE

Spiral type thermal exchanger forms two flow paths, winding around two metal plates in spiral. Multi-tube thermal exchanger forms multiple flow paths by many heat transfer pipes, but spiral type thermal exchanger is a single round flow path so that most of pollutant generated by failure of thermal exchange are not attached but flown in complete countercurrent regardless of its temperature. It has the best efficiency in use of temperature difference of exchanged heat and other excellent features.
