To easily adjust temperatures of all batteries to a predetermined set temperature.SOLUTION: An inlet 30a of a bypass passage 30 is connected to an upper side in the vertical direction relative to mainstream piping 22. Drawing of a gas refrigerant toward the bypass passage 30 enables a liquid refrigerant flowing in the mainstream piping 22 to easily flow toward the downstream side in the refrigerant flowing direction in the mainstream piping 22. This can suppress reduction of a flow rate of the liquid refrigerant distributed to branch piping 23 connected to the downstream side in the refrigerant flowing direction relative to the mainstream piping 22. Since a bypass restrictor is provided in the bypass passage 30, this structure inhibits the liquid refrigerant flowing in the mainstream piping 22 from preferentially flowing into the bypass passage 30. Since the entire bypass passage 30 is located on the upper side in the vertical direction of the mainstream piping 22, this arrangement inhibits the liquid refrigerant flowing into the bypass passage 30 from being discharged to collective piping via the bypass passage 30.SELECTED DRAWING: Figure 3

    【課題】全ての電池を予め定められた設定温度に調節し易くすること。【解決手段】バイパス通路30の入口30aが主流配管22に対して鉛直方向の上方に接続されている。主流配管22内を流れる液冷媒は、ガス冷媒がバイパス通路30に向けて引き込まれることに追従して、主流配管22内を冷媒の流れ方向の下流側に向けて流れ易くなる。よって、主流配管22に対して冷媒の流れ方向の下流側に接続されている分岐配管23に分配される液冷媒の流量が少なくなってしまうことが抑制される。バイパス通路30には、バイパス用絞りが設けられているため、主流配管22内を流れる液冷媒がバイパス通路30へ優先的に流れ込んでしまうことが抑制されている。さらに、バイパス通路30の全体が主流配管22よりも鉛直方向の上方に位置しているため、バイパス通路30へ流れ込んだ液冷媒が、バイパス通路30を介して集合配管へ排出されることが抑制されている。【選択図】図3
