摘要(中)

本研究探討壓電風扇在無線接取器（AP Router）系統狹小空間內，降低熱點溫度的效能，並分析風扇與散熱表面間隙的影響。隨著無線接取器運算能力的提高，熱管理成為一大挑戰，尤其在狹窄空間中，傳統風扇因體積大、能耗高而難以有效散熱。相比之下，壓電風扇具備體積小、能耗低等優勢，非常適合應用於高密度電子設備。
本研究通過實驗測試了單個及雙個壓電風扇在不同間隙配置下的散熱效果，並詳細分析了風扇配置與散熱性能之間的關聯性。結果顯示，在經過優化的最佳間隙條件下，單個壓電風扇能夠有效降低熱點溫度，溫度降幅達到約12.7°C，展示出顯著的降溫效果。而在雙風扇的配置下，風扇之間的協同作用進一步提升了散熱效率，最大溫差達到21.9°C，表明雙風扇的使用能顯著改善設備的熱管理性能。
本研究證實，壓電風扇相較傳統風扇具備明顯優勢，特別是在狹小空間內進行散熱時。它不僅有效降低設備熱點溫度，還具備小型化和節能特性，使其成為替代傳統風扇的潛力解決方案。這些結果為壓電風扇在無線接取器及其他高密度電子設備中的應用提供了實驗支持，未來可進一步優化其設計以提升散熱效能。

摘要(英)

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.
