To study the heat transfer performance of plate heat exchanger, according to the basic test principle and method in engineering thermodynamies, heat transfer theory, and thermal testing technology, cumbined with the current national standard, an experimental platform is developed to test the performance of plate heat exchanger. The platfl^rm applies sensors with high accuracy and a data acquisition board based on the STM32 chip. Also based on visual studio 2008 development environment, and using the techuolugy of dynamic Flash, SQL Server database aml virtual instrument, the software is programmed in c# language. Finally the overall argumentation, design, installation amt debugging of the experiment platform are finished. Performance parameters and heat transfer correlations of the exchanger are acquired based on testing data. Experimental results show that the experiment platform has the following characteristics such as high degree of automation, high control accuracy, high maneuverability, and it provides reliable basis and data support for theoretical study.
