本研究建立一循環式鋰離子電池溫控模組之模型。透過商用軟體COMSOL Multiphysics，根據理論計算出鋰離子電池放電時所產生之熱源，並取其平均值應用於電池模組中進行模擬分析。文中分析模組不同的環境溫度、前導流設計、發泡材參數、內風扇速度以及使用鋁發泡材取代導流版與加熱器鰭片時，模組所需之加熱時間、電池溫度及流場均勻性。
結果顯示，當進入電池前之流場均勻性越好，模組需要的加溫時間越短；前導流區域有四片導流板時，進入電池之流場均勻性較好，電池所需之加溫時間較短；鋁發泡材之孔隙率和滲透率分別在0.8和1×10-7 m2時，有較好的熱傳能力；內風扇速度在2 m/s時，雖然所需之加熱時間短，但會增加表面熱通量之損失，使得加熱器需不斷的啟動以維持溫度，且風扇也需較大的功率來驅動流體；使用鋁發泡材取代導流板與加熱器鰭片時，以圓弧形導流之斜角式凸出發泡材模組在進入電池前之流場均勻性最好，電池所需之加溫時間最短。此模組亦可在高溫或低溫等極端環境下使用，且皆符合電池安全之工作溫度範圍內。

Several designs of thermal control module for circulating lithium-ion battery are proposed and analyzed in this study. Commercial software COMSOL Multiphysics is used. In this research, the heating time, ambience temperature, different diversion design in front of the module, different parameter of metal foam, internal fan velocity and use the metal foam to substitute the deflector and the fin of heater is investigated.
Results show that, due to the flow field into the battery is more uniform, the module which is consist of four deflectors have the less heating time. When the porosity and permeability of metal foam is 0.8 and 1E-7 m2 have the better heat transfer effect, respectively. Although the velocity of internal fan is 2 m/s which have less heating time, more heat loss from surface heat flux and make the heater have to work to maintain the module temperature. The best design is arc shape combine bevel angle metal foam module which have the best uniform flow field and least heating when we use the metal foam to substitute the deflector and the fin of heater. This module also can work at high and low temperature in safe operating limit.
