Abstract
Description
フィルム外装電気デバイスを冷却する外部より供給される冷却風が流れる冷却路を有し、冷却路の流出口となる部分の開口面積が冷却路の流入口となる部分の開口面積よりも大きいことを特徴とする。
枠体の互いに対向する対向面に、フィルムの周縁の熱融着部にて熱融着された熱融着部を挟持する内面が形成されており、内面と反対側の面となる外面に凹凸が設けられ、
他のフィルム外装電気デバイス用ケースと重ね合わされた際に、枠体の外面と他のフィルム外装電気デバイス用ケースの枠体との間に、フィルム外装電気デバイスを冷却する外部より供給される冷却風が流れる冷却路の流入口および流出口が形成され、
冷却路の壁面が、排ガス通路部の側壁、枠体、フィルム外装電気デバイス用ケース内のフィルム外装電気デバイスの表面および他のフィルム外装電気デバイス用ケース内の他のフィルム外装電気デバイスの表面とを含み、
流出口の開口面積が流入口の開口面積よりも大きく、かつ冷却路の流路断面が流入口から流出口に向かうにつれ大きくなる領域を有するものである。
図1に本実施形態のフィルム外装電池の外観斜視図を示す。
本実施形態では並列に配置された2つのフィルム外装電池をまとめて冷却する構成を例示する。
図9に本実施形態のセルケースの外観斜視図を示す。本実施形態のセルケース210も、第2の実施形態のセルケース110と同様に、並列に配置された収納部210aと収納部210bとを有する。収納部210a内にはフィルム外装電池1aが収納され、収納部210b内にはフィルム外装電池1bが収納されている。このように、本実施形態のセルケース210は電池を収納する構成においては、第2の実施形態のセルケース110と同様である。しかしながら、セルケース110は冷却路113Aが排ガス通路111cの両側に2つ形成されているのに対し、本実施形態のセルケース210は1つの冷却路213Aのみを有する構成となっている。
図10に本実施形態のセルケースの外観斜視図を示す。本実施形態のセルケース310も、第2の実施形態のセルケース110と同様に、並列に配置された収納部310aと収納部310bとを有する。収納部310a内にはフィルム外装電池1aが収納され、収納部310b内にはフィルム外装電池1bが収納されている。しかしながら、本実施形態のセルケース310の排ガス通路311cには、冷却風供給路320が形成されている点で第2の実施形態のセルケース110と異なる。
第1の実施形態で示したセルケース10内に冷却風を導入させた場合のフィルム外装電池1の表面上の各部の温度を測定した測定結果を図11のグラフに示す。
