Abstract: The waste heat recovery by heat pipes is an excellent way to save energy. A study was performed on the applications of heat pipe heat exchangers for the heat recovery with energy saving and the effectiveness of the Conventional Heat Pipe (CHP) and Two-Phase Closed Thermosyphon (TPCT) heat exchangers. The relevant papers were analysed to support future works and the experimental studies were summarised. This study also provides the analysis of performance of heat pipe heat exchangers in the heat recovery system.
Key words: Heat pipe, Recovery, Effectiveness
