In this article, we use BR0.3 type plate heat exchanger for experiment,and the heat transfer coefficient of the mixed plate heat exchanger is explored. Through the test platform of plate heat exchanger, a large number of experiments have been done in different mixed mode but the same passageway,and lots experimental data are obtained. By the linear fitting method and the analysis of the data, the main factors which influence the heat transfer coefficient of mixed plate heat exchanger were carried out,and the formula of heat transfer coefficient which fits at any mixed mode plate heat exchanger is obtained, to solve the problem of engineering calculation.The fact, there is no denying that the result which we get has great engineering significance. © (2014) Trans Tech Publications, Switzerland.

BR0.3 type plate heat exchanger was selected as a test object. Experiment test on flow resistance and heat transfer coefficient of a conventional plate heat exchanger with same flow channel and different conventional way under a cold and hot dual-cycle test platform was carried out to obtain corresponding experimental data. A concept of handling resistance was developed by combing the flow resistance on tension side and the flow resistance on pressure side of a conventional plate heat exchanger, proven by theoretical derivation and applied to analyzing the experimental data and formula fitting, thus establishing a general calculation formula for determining heat transfer coefficient and flow resistance. The formula can calculate the heat transfer coefficient and flow resistance of a conventional plate heat exchanger that could not be done before, which is of great help to engineering calculation.
