Compact heat exchangers are important elements as contributors to increased energy efficiency in industry, transport and buildings and augmentation of them in terms of heat transfer has been an important research topic for many years. In spite of manyfrequent efforts for proposingto propose a heat transfer enhancement technique over the past years, there are few researchespieces of research that deal with performance optimization with regards to vortex generators and the efficiency of these winglets is a question and lots. More of efforts is need to improve it. Using winglets causes a higher heat transfer rate with the penalty of pressure lost and balancing between these parameters are nowadays challenging nowadays. In this work, enhancement of CHE by using a multi objective optimization with regards to heat transfer rate and pressure drop is carried out.
