Aiming at the flow performance of gas-water multiple-tube side heat exchanger, a numerical simulation based on FLUENT software was carried out for airflow distribution uniformity of the split range channels, with the influence analysis on the ununiformity and energy loss under different conditions of the heat exchanger tube arrangement number, vertical section guide angle. The simulation results show that heat exchanger tube arrangement number have important impact on the ununiformity and energy loss, the left guide angle have significant impact on ununiformity, but the right guide angle have little influence when single side angle change, and with the increase of them, the energy loss increase slightly. When both side angle change, ununiformity and energy loss become fluctuate, and overall evenly distributed effect is lower than single side angle. Within the scope of this study, the structure of split range channels is recommended that left angle is 78.7°, and right angle is 90°. The numerical simulation can provide the basis for similar compact multiple tube side heat exchanger diversion technology development.
