| dc.description.abstract | This study investigates the effectiveness of piezoelectric fans in reducing hotspot temperatures within the confined space of an AP (Access Point) router system and analyzes the impact of fan-to-surface clearance. As the computational power of AP routers increases, thermal management has become a major challenge, particularly in confined spaces where traditional fans struggle to provide efficient cooling due to their large size and high energy consumption. In contrast, piezoelectric fans offer advantages such as compact size and low power consumption, making them highly suitable for high-density electronic devices.
In this study, the cooling performance of single and dual piezoelectric fans was tested under different clearance configurations, and the correlation between fan configurations and cooling performance was analyzed in detail. Results showed that, under optimized clearance conditions, a single piezoelectric fan effectively reduced hotspot temperatures with a temperature reduction of approximately 12.7°C, demonstrating a significant cooling effect. In a dual-fan configuration, the synergistic effect between fans further enhanced cooling efficiency, achieving a maximum temperature difference of up to 21.9°C, indicating that dual fans can significantly improve thermal management.
This study confirms that piezoelectric fans have clear advantages over traditional fans, especially for cooling in confined spaces. Not only do they effectively reduce device hotspot temperatures, but they also feature miniaturization and energy-saving benefits, making them a potential alternative to traditional fans. These findings provide experimental support for the application of piezoelectric fans in AP routers and other high-density electronic devices, and future design optimizations could further enhance their cooling performance. | en_US |
