Abstract
Description
バッテリーモジュールのPCMを適用したヒート・シンクの冷却効果を分析するために、PCMの適用によるバッテリーモジュールのヒート・シンク温度変化を比較した。比較例と実施例は、両方同一の容量及びサイズのバッテリーモジュールを対象としたが、バッテリーモジュールのヒート・シンクにPCMを適用した部分のみ異なる。ヒート・シンクの流入口へ流入される冷却流体の温度は20±5℃に設定し、PCMの適用によるヒート・シンク流出口の温度とバッテリーモジュールの全体の温度勾配を比較した。
図1は、例示的なバッテリーモジュールのヒート・シンク熱流動の解釈模式図である。
図3は、例示的なバッテリーモジュールの冷却流路を細分化した冷却流体による温度勾配を示す結果である。
図4は、本発明の一実施例によるPCMカプセルをバッテリーモジュールのヒート・シンクに反映した模式図である。
