本文以Fluent分析軟體來模擬求解流體在水冷系統中之溫度對流熱傳情形。運用CFD數值模擬解析方式，模擬水冷系統內之溫度、流場之情況，並改變不同Re數及不同熱源溫度，並將模擬解析所得結果用以評估對水冷系統散熱效益的影響，提出合適之搭配模式及相關資料。
水冷系統為一個由Chiller、Thermal head、Water tube、Thermal control unit、PT sensor等零件組成。此水冷系統(Active Temperature Cooling System)被廣泛使用於半導體後段IC測試使用，例如福雷電、矽品、京元等IC測試廠。
由於此水冷系統使用於IC測試是近年來的新技術，Nvdia和ATI的繪圖晶片IC皆是使用此水冷系統來做電性測試。而本文利用Fluent分析軟體來模擬求解流體在水冷系統的Thermal head(IC測試頭)中之溫度對流熱傳情形。數值模擬顯示出，流速及IC測試所產生的高溫皆會影響溫度對流熱傳情形，本文將水冷系統內所模擬結果的流場繪製並討論之。

This article is to analyze the behavior of laminar flow and heat transfer in a Active Cooling System. The CFD simulating scheme is applied to analyze the flow fields in the ATC system.

ATC system includes Chiller, Thermal head, Water tube, Thermal control unit and PT sensor etc. And ATC system is used extensively for IC testing by semiconductor company (ASET, SPIL, KYEC…).

Due to ATC system is a new technology, Nvdia and ATI company use this technology for graph IC testing. This paper studies the behavior of laminar flow and heat transfer in a thermal head on Active Cooling System.The software, FLUENT (Copyright (C) 2004 Fluent Inc.) is used to simulate the flow fields. Here the SIMPLEC algorithm is chosen in this software.
