摘要

隨著個人電腦的普及其效能之提升，帶動了散熱技術之演進，進而提升熱管散熱模組的需求量和性能要求。在大量散熱模組之生產需求下，品質管理檢測的議題也越來越受到重視，而現下檢測時間過長之問題，將導致生產效率降低、成本增加。
本研究主題為規劃一套熱管散熱模組之完整實驗方法與流程，藉此分析熱管散熱模組各部元件之溫度反應，在不同實驗參數下之的變化；實驗參數主要包含加熱方式、加熱量、風扇開啟時間等。另一方面，運用塊狀系統之理論為基礎，建立一套數值模擬方法來預估熱管散熱模組之動態溫度反應，幫助實驗參數之制定，減少以試誤法求得之檢測參數與判斷準則之時間及成本。
本研究藉由模擬結果求得適當之檢測參數範圍，證實建立散熱模組的模擬方法之可行性，並配合實驗結果得出在不同加熱方式下，各種適當的檢測參數與判斷方法。最終透過動態檢測的方法制定，將測試時間縮短為30秒，提高效率。

The higher penetration rate and better performance efficiency of personal computer (PC) nowadays has led to the improvement of cooling technology, increasing demand, and higher quality requirement of heat pipe cooling module. Following this trend, the topic of Quality Management becomes more and more important. Therefore, the existing problem of long examination process, which causes worse manufacturing efficiency and higher cost, turns to be one issue to be further improved in cooling field.
Our research focus on designing the experiment methodology and process for heat pipe cooling module, and try to analyze the temperature response change of each component in heat pipe cooling module under different situations. The main experimental parameters include the heating methods, heating temperature, and time to turn on the fan. In addition, based on Lumped System theory, we build up a simulation model to find out the dynamic temperature response of heat pipe cooling module, and then set up experimental parameters. Under this simulation, we could reduce the time and cost on testing parameters and analysis principles with try and error method.
The study proves to be the successful simulation model to find out suitable parameters range and analysis principles under different heating methods. Finally, our research results successfully shorten the examination time to 30 seconds through transient examination method.
