| description abstract | The thermal characteristics of exit flow issued from an axial fan widely used for impingement cooling of power electronics are experimentally studied. A new fan configuration is proposed to improve the impingement cooling performance at the center of a uniformly heated flat plate. Results demonstrate that the addition of fin attachments to the fan hub housing the driving motor intensifies reverse flow from the plate, leading to enhanced local heat transfer (up to 12%) relative to that of a reference fan. The effectiveness of hub fin attachments is limited to relatively short impinging distances (H/D<0.6). | |
