The classification of the heat exchangers and theory research

Abstract

The Heat Exchangers which could transfer the heat from hot fluid to cold fluid is used widely in industry. Article describe the classification of the Heat Exchangers, according to the working principle, can be divided into the hybrid Heat Exchangers, surface Heat Exchangers and regenerative Heat Exchangers three categories. The hybrid Heat Exchangers is through direct mixed the hot and cold fluid to exchange heat. The surface Heat Exchangers uses a wall to separate the cold and hot fluid to exchange heat. The regenerative Heat Exchangers make the cold and hot fluid flow through the same heat transfer surface in turn to exchange heat. At same time, the factors which put effect in turn to performance of Heat Exchanger are illustrated in this paper as well as the evaluating criterion, a new approach for the analysis of the Heat Exchanger performance. Finally the article reviews the domestic research on Heat Exchanger of deficiencies in the process of development, the domestic researches on the Heat Exchanger to put forward some further development prospect.
