dc.description.abstract摘要 本研究首先以相同製程參數製作外徑6mm,長度187mmm與300mm的燒結式導熱管。並藉由理論與實驗兩種方式,探討不同管長與圓直管經過機械加工(壓扁、彎管、彎管再壓扁)之後,於標準測試下的最大熱傳量。研究結果顯示最大熱傳量會隨著有效長度的減小、截面積的增加與機械加工的製程的減少而增加。有鑒於此,本文利用置中加熱、雙邊冷卻的量測方式,探討導熱管在不同安裝方式的最大熱傳量。研究結果顯示:導熱管於中段加熱,最大熱傳量會提升2.75~3倍。提高熱傳性能有兩項重要因素:其一為加熱位置居中,導致有效長度均分為左右兩端,所以工作流體可以迅速地回流蒸發端;其二為中段加熱導熱管,可以視為在一個發熱源上,安裝兩支有效長度較短的導熱管輸出熱源功率。因此,導熱管採取置中加熱,兩端冷卻的散熱性能優於標準(Qmax)的散熱性能。zh_TW
dc.description.abstractAbstract In the beginning of this study, I used the same production process parameters to produce two kinds of sintered heat pipes: one is of 6mm in diameter and 187mm in length and the other is of 6mm in diameter and 300mm in length. Then, through theoretical and experimental methods, I examined these two sintered heat pipes'maximum amount of heat transfer under standard testes after they were mechanically processed in three ways: flattened, bent, and bent with flattened. The results showed that the maximum amount of heat transfer would increase with the reduction of effective length and increase of cross section area as well as the reduction of mechanical processing. In view of the results, I examined how the maximum amount of heat transfer would be affected by different installation by means of heating the middle part and cooling the two ends of pipes. The results showed that the maximum heat transfer capacity will increase by 2.75~3 times when the middle part of the pipes was heated. There are two explanations for such a phenomenon. Firstly, when the middle part of the pipe is heated, the effective length is equally divided into two and therefore fluid can quickly go back to the evaporation points. Secondly, heating the middle part of heat pipe can be regarded as heating source which is installed with two shorter heat pipe to output heat. Therefore, the heat pipes' thermal evaporation is superior to standardized thermal evaporation when they are heated in the middle part and cooled at the two ends.en_US
