Description
これにより、充放電によって蓄電体が膨張した場合でも、熱交換部の範囲に固定された伝熱シートの弾性変形によってその変位量を吸収することができる。蓄電体の体積の変位量が大きい場合でも、熱交換部は厚み方向に立設する仕切り部材によって剛性が高くなっているので、蓄電体の押圧力によって流体通路が潰れることもない。また、入口側空隙部及び出口側空隙部に対応する範囲には伝熱シートがない構成となっているので、蓄電体の膨張スペースが確保され、入口側空隙部及び出口側空隙部が伝熱シートを介して蓄電体に押圧されることもない。このように、蓄電体の膨張が生じても平板部の冷却流体が流れる流路が保護される構成となっている。更に、リチウムイオンキャパシタ等の蓄電体においては一般的に、内部の発熱エレメントが外周部にないため、ウォータジャケット(平板部)の全面に伝熱シートを配置するよりも、効率的に冷却することができる。
これにより、内側面から起立する複数の切り込み部によって平板部が内側から支持されるので、押圧力に対する剛性を効果的に向上させることができ、熱交換部を形成する流体通路をより確実に保護できる。
これにより、各平板部への冷却流体の供給及び回収をシンプルな構成で実現することができる。
なお、本実施例では、第1・2延長片421・422より筒状部441を一体的に設けているが、個別の環状部材を設けて、接続管60を固定してもよい。
また、本実施例では、接続管60の開口部68を短径断面に切り込む形状としているが、接続管60の法線方向に複数の穴を設けるようにしてもよい。
蓄電装置1が備える冷却部材35は、蓄電体21と交互に配置され、その内部に冷却流体が流れるウォータジャケット40と、蓄電体21とウォータジャケット40の間に配置され、弾性変形可能な熱伝導シート30と、を備える。ウォータジャケット40の内部には、ウォータジャケット40における冷却流体の入口に連通する流体分配部70と、ウォータジャケット40における冷却流体の出口に連通する流体回収部72と、流体分配部70と流体回収部72の間でウォータジャケット40の厚み方向に立設するフィン80によって仕切られた流体通路71により、流体分配部70と流体回収部72を接続する熱交換部67と、が形成される。熱伝導シート30は、本体部41の表面における熱交換部67に対応する範囲であって流体分配部70及び流体回収部72に重ならない範囲に配置(貼付)される。
更に、リチウムイオンキャパシタ等の蓄電体においては一般的に、内部の発熱エレメントが外周部にないため、ウォータジャケット40の全面に熱伝導シート30を配置するよりも、効率的に冷却することができる。
また、蓄電体21はリチウムイオンキャパシタに限定されず、リチウムイオンバッテリーを含む発熱と膨張をする蓄電体にも適用することができる。
更に、フィン80については、鋳造等一般的な金属成形方法により製造することも可能であり、形状についても本実施例に限定されるものではない。
