物理機制裡有一種「相變冷卻技術」，利用物質狀態改變時吸收潛熱的散熱方式，這種不需要能源驅動的被動冷卻方式，具備環保、高效率的優點，應可適用於高性能資料處理中心的機櫃伺服器的冷卻上。如何將冷卻分配系統 (Cooling Distribution System, CDS) 發揮節能效益，乃為研究的課題。
本研究以機櫃伺服器發熱須冷卻的環境發想，選用丙酮與水混合液作為熱傳媒介。熱源是使用加熱平板，其實驗溫度設定為50 ℃、60 ℃、70 ℃及80 ℃，每個溫度階段的加熱時間為4分鐘。實驗混合液的體積合計為100ml或200ml。以100ml為例，若丙酮5ml則水溶液95ml，以不同濃度相同體積與不同溫度作為實驗參數。冷卻則使用TEC1-12710致冷晶片作降溫元件。觀察燒杯內丙酮與水混合液混合後，同時加熱冷卻的相變化 (Phase transition) 的熱傳現象。
在實驗比例裡，以丙酮30ml+水溶液70ml為最佳曲線比例。以氣相溫度來看，加熱到達沸點溫度56 ℃前，溫度曲線平穩，在加熱60 ℃~70 ℃區間進入氣體轉變成液體的凝結放熱過程，開始升溫。以液體的相變溫度來看，在加熱50 ℃~60 ℃區間是氣化潛熱冷卻相變平台較為平穩，在加熱60 ℃~70 ℃區間進入相變潛熱現象溫度則緩慢爬升，以上是本次研究的最佳比例。

The cooling technique by phase change utilizes the absorption of latent heat during the change in the state of matter. This passive cooling method is environmentally friendly and highly efficient, making it suitable for cooling servers in high-performance data centers. Therefore, maximizing the energy efficiency of the Cooling Distribution System (CDS) is essential for further development of AI related data centers.
This study focuses on using an acetone-water mixture for liquid cooling applications. A heated plate was adopted as the heat source with the heating conditions set to constant temperatures of 50 °C, 60 °C, 70 °C, and 80 °C, respectively. The total volume of the experimental mixture was either 100ml or 200ml. For example, 100ml would consist of 5ml of acetone and 95ml of aqueous solution. Different concentrations at the same volume and different temperatures were used as experimental parameters. A TEC1-12710 cooling chip was used as the cooling element. The heat transfer phenomena were observed for their cooling analysis.
Among the experimental ratios tested, the combination of 30 ml of acetone and 70 ml of water tends to give a better cooling performance. Regarding the gas-phase temperature above the liquid mixture, the temperatures remain stable until the boiling point of 56 °C of acetone is reached; as heating progressed to the 60°C–70°C range, the system enters into the exothermic condensation process of acetone, thus accompanying a rise in temperature. Regarding the liquid-phase transition temperature, a relatively stable plateau associated with the latent heat of vaporization cooling is observed between 50°C and 60°C, followed by a gradual temperature rise in the 60°C–70°C range as the sensible heat comes into play.
