Performance Test System of Heat Transfer and Flow Resistance of Heat Exchangers Merged with Virtual Instrument Technology
A recently-built heat transfer performance testing system for a heat exchanger manufactory is presented with its hardware structure, operation principle, and software control and measurement system. Working fluids of the subsystem include thermal conducting oil, compressed air, glycol water solution and water as the heating fluids, and air and water as cooling fluids. The heat transfer performance test of heat exchangers can be conducted not only for conventional one heating fluid to one cooling fluid, but also for compound air cooling heat exchanger with two or three heating fluids in parallel or in series. Control and measurement system is implemented based on LabView software platform, consisting of data acquisition and process system, and automotive operation and control system. By using advanced measuring instrument combined with sound computer software control, the test system has characteristics of compact in structure, high accuracy, wide range of testing scope and friendly in operation interface. The uncertainty of the total heat transfer coefficient K is less than 5％. The testing system provides a reliable performance test platform for designing and developing new heat exchangers.
