Zigzag flow channel is a typical flow channel adopted in printed circuit heat exchanger due to high heat transfer performance. The roundness of edge for the zigzag flow channel affects to the thermal-hydraulic performance of the zigzag flow channel. In this study, the numerical analyses were conducted for the zigzag flow channels with rounded edge, and the effects of the Reynolds number, inclination angle, and the edge shape were examined. As a result, the correlations were derived to predict the thermal-hydraulic performance of the zigzag flow channels with the rounded edge.
