本研究目的為自行設計高功率CPU之水冷頭,並藉由田口方法改變水冷流道結構,解決熱源表面因溫度分布不均,使其效能降低的問題。
首先透過降溫實驗與能量守恆定律計算環境的熱對流係數(h),作為模擬邊界條件。
以市售水冷頭搭建溫測模組,實際量測散熱溫度,並以COMSOL Multiphysics軟體進行熱流場數值分析,代入前段熱對流係數,比較實驗與模擬之熱阻曲線,以實驗驗證軟體可靠性。
接著重新設計適用高功率熱源水冷頭,改變流道內板式鰭片厚度與間距關係,以數值方法求得熱源表面中心最低溫搭配。
最後利用田口方法提出針對流道結構的數個控制因子,進行模擬分析與統計,歸納使熱源具最佳均溫性之設計。
結果證實可改善傳統結構水冷頭均溫性7.6%,並且整體溫度下降0.35℃。
The purpose of this study is to design a water cooling block for high power CPU and change the water cooling flow channel structure by Taguchi method to solve the problem of non-uniformity temperature distribution on the surface of the heat source, which reduces its efficiency.
First, the heat convection coefficient (h) of the environment is calculated by the cooling experiment and the law of energy conservation as the boundary condition for the simulation. The temperature measurement module is built with commercially available water cooling block to measure the actual heat dissipation temperature, and the COMSOL Multiphysics software is used to analyze the heat flow field value and substitute the heat convection coefficient in the previous section to compare the experimental and simulated thermal resistance curves for experimental verification of software reliability. Then, I redesigned the water cooling block for high power heat source and changed the thickness and spacing of the fins in the runner to obtain the minimum temperature match at the center of the heat source surface by numerical method. Finally, the Taguchi method was used to propose several control factors for the flow channel structure, and simulations and statistics were conducted to summarize the design of the heat source with the best temperature uniformity.
The results proved to improve the temperature uniformity of conventional structured water cooling block by 7.6% and reduce the overall temperature by 0.35℃.
