BATTERY MODULE

To provide a technique effective for securing adhesiveness between a battery and a cooling tube while suppressing a restriction load restricting a plurality of batteries and the cooling tube in a battery module where the plurality of batteries is cooled by the cooling tube in a meandering shape.SOLUTION: A battery module 101 comprises: a plurality of batteries 10 disposed while being separated by spacing S in a first direction X; a cooling tube 20 for cooling the plurality of batteries 10; and a restriction part 30 restricting the plurality of batteries 10 and the cooling tube 20 in the first direction X. The cooling tube 20 is formed in a meandering shape by combining a plurality of heat exchange parts 21 and a plurality of bending parts 24, and the bending part 24 is deformable to be bent in the first direction X in response to a restriction load F received from the restriction part 30 and is configured in such a manner that bending rigidity in the first direction X is lower than that of a comparative bending part. The comparative bending part is defined to be obtained when the bending part 24 temporarily consists of a same material as the heat exchange part 21 so as to have a same cross-sectional shape.SELECTED DRAWING: Figure 2 【課題】複数の電池を蛇行形状の冷却管で冷却する電池モジュールにおいて、複数の電池と冷却管を拘束する拘束荷重を低く抑えつつ電池と冷却管の密着性を確保するのに有効な技術を提供する。【解決手段】電池モジュール１０１は、第１方向Ｘに隙間Ｓを隔てて配置される複数の電池１０と、複数の電池１０を冷却する冷却管２０と、複数の電池１０と冷却管２０を第１方向Ｘに拘束する拘束部３０と、を備え、冷却管２０は、複数の熱交換部２１と複数の湾曲部２４とを組み合わせて蛇行形状をなすように構成されており、湾曲部２４は、拘束部３０から受ける拘束荷重Ｆに応じて第１方向Ｘに曲がり変形可能であり、第１方向Ｘの曲げ剛性について比較湾曲部を下回るように構成されており、比較湾曲部は、湾曲部２４を、仮に、熱交換部２１と同一の材料で同一の断面形状を有するように構成したとしたときに得られるものと定義される。【選択図】図２
