摘要

This study investigates the effect of aspect ratio on the thermal performance of a crossflow heat exchanger with longitudinal wall conduction. This study uses a numerical method to calculate the exit mean temperatures and effectiveness for various aspect ratios. The results indicate that there exists a maximum effectiveness along with an increase of aspect ratio. The maximum occurs when the aspect ratio is equal to one when the flows are balanced, and it moves to where the aspect ratio is larger than one when the flows are unbalanced. For industrial applications, this study suggests that the square shape is the best choice for the design of a crossflow heat exchanger.
