Design and Performance Analysis of a Compact Printed Circuit Heat Exchanger (PCHE) Used in the Waste Heat Recovery Systems (WHRS) in Ships

open access: yes, 2018
In order to increase the energy efficiency in ship operations, the waste heat recovery systems (WHRS) that recover heat from ship’s main engine exhaust gases are commonly used. Because conventional shell and tube heat exchangers are heavier and take up larger space, the usage of micro-channel heat exchangers, namely diffusion-bonded printed ...
