摘要：
This work investigated experimentally the heat transfer and pressure drop in electronic module using a curved deflector to direct the flow towards the recirculation zone enclosed between the two heat sources. The experiments were carried out to investigate the effect of deflector dimensionless radius (Rr) and both horizontal and vertical distances (Rx, Ry) within a range of Reynolds number from 5223 to 11,380. The results show that larger deflector at small vertical distance enhances the heat transfer for upstream and downstream heat sources while the horizontal distance has a contrast effect. Correlations are obtained for the average Nusselt number of both upstream and downstream heat sources utilizing the present measurements within 5223 ≤ ReL ≤ 11,380, 0.02 ≤ Rx ≤ 0.4, 0.3 ≤ Ry ≤ 0.5 and 0.15 ≤ Rr ≤ 0.35.
