Abstract:	本研究主要分為兩個部分。第一部分探討太陽能模組在不同風速條件下，對模組峰值溫度的影響及其降溫效率；第二部分則分析熱傳結果對有無鋁框模組所造成的熱應力差異。在太陽能模組的熱傳分析中，研究結果顯示水冷卻對模組降溫具有顯著效果，而風的存在也能有效減緩模組溫度的上升，且隨著風速增加，降溫效果愈加明顯。當水冷卻系統結合不同風速條件時，可進一步提升模組的整體降溫效率。在熱應力分析部分，研究著重於比較有無鋁框模組在相同熱載重下的熱應力峰值及其分布情形。結果顯示，有鋁框模組的拉伸應力顯著低於無鋁框模組，且在施加冷卻條件下，拉伸應力可維持在電池不易損壞的安全範圍內。此外，有鋁框模組的應力峰值分布區域亦較無鋁框模組小。由此可見，在冷卻過程中，鋁框能有效約束模組變形，進而提升模組的穩定性及使用壽命。 ;This study is mainly divided into two parts. The first part investigates the effects of different wind speeds on the peak temperature of solar modules and their cooling efficiency. The second part analyzes the thermal stress differences caused by the presence or absence of an aluminum frame based on the thermal analysis results. In the thermal analysis of solar modules, the results indicate that water cooling has a significant effect on reducing the module temperature. Additionally, airflow effectively slows down the temperature rise of the module, and the cooling effect becomes more pronounced as wind speed increases. When the water cooling system is combined with varying wind speeds, the overall cooling efficiency of the module is further enhanced. Regarding the thermal stress analysis, the focus is on comparing the peak thermal stresses and their distribution in modules with and without an aluminum frame under the same thermal load. The results show that the tensile stress in modules with an aluminum frame is significantly lower than that in frameless modules. Moreover, under cooling conditions, the tensile stress can be maintained within a safe range that prevents damage to the solar cells. Furthermore, the stress peak distribution area in framed modules is considerably smaller than in frameless ones. These findings indicate that during the cooling process, the aluminum frame effectively constrains module deformation, thereby improving the stability and service life of the solar module.
