| dc.description.abstract | 本研究設計了用於光轉換模組連接器冷卻的平板?片，並對這些
熱交換器進行了性能測試。製造四種不同?片長度（L = 15、30、45、
60 mm），並進行風洞測試，以比較其熱傳性能和壓降。
實驗結果顯示，在不同風速下，當加熱功率從 5 W 增加到 20 W
時，各?片長度的加熱中心溫度均低於所需的 80℃。最佳的?片長度
取決於風速，介於 30 mm 和 45 mm 之間。當加熱功率增加到 30 W
時，在風速高於 2 m/s 的情況下，45 mm 長度的?片提供了最低的加
熱中心溫度。隨著空氣流速和?片長度的增加，空氣流過?片陣列的阻
力也增加。較長的?片提供了更大的熱傳遞面積，但也造成更高的流動
阻力。這導致對於固定風扇功率的?片-風扇組合而言，氣流速度較低，
從而降低整體熱傳遞性能。綜合這兩種效應，30 mm 至 45 mm 長的
?片在熱傳性能上優於較短或較長的?片。 | zh_TW |
| dc.description.abstract | This study designed plane fin arrays for the cooling of optical module
connectors and provided a performance test of those heat exchangers. Four
fin lengths (L = 15, 30, 45, 60 mm) were fabricated for wind tunnel testing
and their heat transfer and pressure drop performance was compared.
The test results show that the heating center temperature of each fin
length is lower than the required 80 oC under different air velocities for
heating rate from 5 W to 20 W. The optimal fin length varies depending on
the wind speed, which is between 30 mm and 45 mm. While the heating rate
is increased to 30 W, the 45 mm length fins provided the lowest heating
center temperature at air velocities higher than 2 m/s. The resistance for air
flows through a fin array increased with increasing air velocity and length of
fins. Longer fins provide larger heat transfer area but also caused a higher
flow resistance. This resulted in a lower air flow velocity for a fixed fan
power fin array-fan assembly and degraded the overall heat transfer
performance. The combination of these two effects caused the 30 mm to 45
mm long fins provided better heat transfer performance than shorter or
longer fins. | en_US |
