dc.description.abstract本文研究熱電致冷器之基本特性,並探討散熱器對熱電致冷器之性能影響與熱電致冷器應用於LED散熱之實用性。首先以數值模擬分析散熱鰭片於自然對流下之散熱能力,並以實驗驗證數值模擬之結果。由此數值模擬結合熱電致冷器之運作原理進一步計算熱電致冷器配合散熱鰭片與一發熱源在自然對流下之散熱效果。本研究再以熱電致冷器做為LED之散熱元件,以實驗方法量測在自然對流下,不同規格熱電致冷器應用於不同封裝型式LED之散熱效果。研究結果發現熱電致冷器應用於LED散熱上能有效提高LED之照度。此外不同封裝型式與對溫度的敏感度不同之LED對於熱電致冷器的效果也不相同,研究發現對溫度較敏感之LED在以熱電致冷器降溫時照度提升百分比也會較高。zh_TW
dc.description.abstractThis article discusses the effect of heat sink on the performance of thermal electric cooler and takes advantage of the thermal electric cooler on the thermal management of LED. This study uses the numerical methods to calculate the temperature of heat sink under the nature convection which is validated by an experimental work procedure simultaneously. Combine the numerical methods with the basic theorem of thermal electric cooler to calculate the cooling efficiency of the cooling system which contains a heat source and a heat sink with thermal electric cooler under the natural convection. Furthermore, a cooling device with thermal electric cooler on LED is setup to measure the cooling efficiency between different types of thermal electric cooler and LED. The results show that the use of thermal electric cooler as a cooling device on LED is efficient to increase the illuminance of LED. The effects of thermal electric cooler on different packaging types of LED and temperature of LED are different. The results show that usages of the thermal electric cooler to decrease the temperature of LED and to increase the illuminance are efficient.en_US
