摘要

本研究探討各式引擎冷卻系統的設計及各設計參數的敏感度並開發引擎冷卻系統模擬及分析的技術，從系統設計的觀點來幫助業者設計及選配合適的引擎冷卻系統零組件。數學模型以Fortran語言編寫，可容納無限多個各式熱交換器，對其大小、位置及組合也沒有任何限制；風扇的形式不論是送風扇(pusher fan)或吸風扇(puller fan)程式皆會自動修正其性能曲線並含有黏滯驅動器(viscous drive)的功能。人機介面以Visual Basic撰寫，具有友善且易於使用的人性設計。資料庫則是以Access 2000編寫。各零組件擁有自己的模組(module)及性能曲線資料庫。本軟體的設計符合台灣中小企業的特性及負擔能力，它的研發成功相信對台灣車輛零組件設計開發能力的提升有很大的幫助。

In this work, after studying various engine cooling systems and their components, a computer aided engineering (CAE) software has been developed to assist engine cooling system engineers in the design of the system and the selection of components. The mathematical model of the software is written in Fortran language and has no limitations on number, size and combination of various heat exchangers. The fan model, which includes the viscous drive function can handle both puller and pusher fans. The database function is implemented in the Access 2000. Every component has its own module and performance database. The graphical user interface of the mathematical model and the database is written in Visual Basic language and designed very user-friendly. Since this CAE program is specifically good for Taiwan's medium-small business environment, the success of the project will promote the design and development capability of vehicle components in Taiwan.
