臺灣博碩士論文加值系統

目前市面上資料中心伺服器散熱大多使用冷卻液分配單元(Coolant Distribution Unit)方式冷卻，冷卻方式主要有氣冷及液冷，現在主要的冷卻技術大多是氣冷式，然而隨著資訊設備的能源使用量逐漸升高以及各國普遍對電力使用效率(Power Usage Effectiveness)的要求，氣冷式的散熱方式已漸漸不敷需求，取而代之的是液冷技術的運用，而液冷技術中的浸沒式冷卻(Immersion cooling)更是在噪音、能源效率、可靠度方面的改善與氣冷式比皆有提升，根據測試結果顯示，相較於直接使用氣冷，浸沒式液體冷卻系統約可減少10 %能源用量。
本研究將進行浸沒式冷卻系統的設計及相關測試，並將測試數據進行分析，由於該冷卻系統在國內外尚屬剛起步階段，相關測試報告及數據仍待求證，因此未來在商業化的應用及尋求參數的最佳化是大家努力的目標。

Most data center servers on the market use CDU(Coolant Distribution Unit)for cooling at the present time. Now the main cooling technology is mostly air-cooled. However, with the energy consumption of information equipment has elevated, and the requirements for PUE(Power Usage Effectiveness) in various counties. The immersion cooling among liquid cooling technology has improvements in noise, energy efficiency, and reliability compared with air cooling. According to test results, immersion liquid systems can reduce energy consumption by about 10 %.
The study will carry out the design and related tests of the immersion cooling system, and analyze the test data. Since the cooling system has enlightened interior and oversea, relevant test reports and data are still to be verified. Our goal of efforts is to be applied in commercialization in the future and seek the optimization of parameters.
