Flow characteristics across a fin-tube heat exchanger, which is installed at an angle to air stream in the flow passage of the air-conditioning equipment, are investigated. Already, velocity measurements and flow visualizations are performed in both the inlet and exit chamber of the heat exchanger. As for the flow characteristics in the equipment are in general agreement with results of flow visualization tests implemented in the test section which was made with particularly manufactured Plexiglas. Also, numerical calculation results on the flow patterns by the finite volume method agree well with flow visualization results. Analytical and experimental attempts help us to understand effects of the flow incidence angle and Reynolds number on the performance of the heat exchanger. Lastly, it compared the flow characteristics of in-line arrangement tubes model which manufactured newly and staggered arrangement tubes model by the visualization methods.
