The new type of heat exchanger uses the micro heat pipe as the main heat transfer material. Compared with the traditional heat exchanger of the same kind, the performance of the new type of heat exchanger has significantly improved. By studying the evaluation method of strengthening the performance of the heat exchanger, the performance of the heat exchanger can be further optimized. Most of the current literature study the heat transfer coefficient of the heat exchanger, but there are many influencing factors. Therefore, the evaluation lacks accuracy, and there is no clear research description of fin strengthening performance of the heat exchanger. In this paper, the PEC and jf methods were used in evaluating the enhanced performance of a new type of heat exchanger. Multiple performance indexes were used as evaluation factors and the characteristics of flow and heat transfer were analyzed by studying the working medium, heat transfer coefficient and pressure drop in the heat exchanger. The study, therefore, proposed an optimization direction and the results proved that PEC and jf methods can be used to evaluate the performance of the new heat exchanger efficiently, and the two conclusions were similar. The fins were more capable to improve the performance of heat exchanger when >31000.
