HYBRID TYPE CONSTRUCTION MACHINE
PROBLEM TO BE SOLVED: To provide a hybrid type construction machine comprising a battery temperature controller that can maintain the heat transfer efficiency between a power storage device and a heat exchange member with stability, independently of change in environmental temperature.SOLUTION: A power storage device 8 is configured to have a plurality of battery cells 30 laminated via an insulation separators 31. Each of the plurality of battery cells 30 has one surface thermally coupled with a water jacket 24 that is a heat exchange member via a heat conduction sheet 36, and is fixed to the heat exchange member 24 by using a fixing member so that a compressive force acts on the heat conduction sheet 36. The fixing member is configured to include an upper stay 34 pressing the battery cell from above.
【課題】環境温度の変化によらず、蓄電装置と熱交換部材との間の伝熱効率を安定に維持可能なバッテリ温調装置を備えたハイブリッド式建設機械を提供する。【解決手段】蓄電装置８を、絶縁性のセパレータ３１を介して積層した複数の電池セル３０を持って構成する。複数の電池セル３０は、その一面が熱伝導シート３６を介して熱交換部材であるウォータジャケット２４と熱的に結合し、かつ熱伝導シート３６に圧縮力が作用するように、固定部材を用いて熱交換部材２４に固定する。固定部材は、電池セルを上方から押圧する上部ステイ３４を含んで構成する。【選択図】図４
