摘要

本研究目的為使用CFD之方法，來探討機油冷卻器之熱傳以及了解機油冷卻器之構造，並加以設計出最佳外型。機油冷卻器最主要裝置於機車上。騎乘時利用空氣將機油冷卻器散熱，而在內部管路則利用由油通過機油冷卻器模型散熱，藉由模擬來探討散熱的趨勢。此種機油冷卻器排數為15排，因格點過多造成模擬上有困難需要簡化，使用多孔介質比較速度與壓力差證明簡化可行。接著利用簡化模型，模擬結果。接著藉由田口法設計管路；例如高度、寬度、角度、溫度，利用兩種評價各自乘上權重比例，得到最佳水準，將會落在高度於2.1mm、寬度為3mm或是4mm、角度為13度、溫度為350K。

This study aims to use CFD methods to explore the oil cooler heat transfer. Understanding oil cooler construction, and design the best heat transfer. Oil cooler most device on motor. The use of air makes oil cooler heat dissipation by riding and in internal pipeline is uses by oil through oil cooler, to discussion the heat dissipation of trend. This oil cooler have 15 row, using porous media and full module simulation results of speed and pressure to simplified model. Then uses simplified model, Then through Taguchi method design pipeline, such as height, and width, and angle, and temperature , uses two species evaluation to find the best value. The best value is at height 2.1mm, width 3mm, angle 13o, temperature 350K.
