A heat exchange structure for a battery in which a heat exchange panel (42) and a battery cell (41) are arranged in parallel in close contact with each other so that a heat exchange wall (421) of the heat exchange panel (42) through which a heat exchange fluid circulates is formed along a side surface (4411) of the battery cell (41), the heat exchange wall (421) along the side surface (411) of the battery cell (41) being formed from a flexible thin plate, and preferably, the heat exchange panel (42) is formed from a flexible thin plate. In the heat exchange panel (42), a flow path wall (425), which defines a flow path through which a heat exchange fluid circulates along the heat exchange wall (421), is provided so as to be capable of expanding and contracting in the vertical direction. Heat exchange between a heat exchange panel and a battery cell can be efficiently performed, and high heat exchange efficiency can be stably maintained even when expansion of the battery cell occurs.
一种蓄电池热交换构造,以使供热交换用流体在内部环流的热交换面板(42)的热交换壁(421)沿着电池单元(41)的侧面(4411)的方式将热交换面板(42)和电池单元(41)紧贴地并排配置,沿着电池单元(41)的侧面(411)的热交换壁(421)由可挠性薄板形成,优选的是,在热交换面板(42)内对使热交换用流体沿着热交换壁(421)环流的流路进行划定的流路壁(425)设置成能够沿竖立设置方向进行伸缩。能够高效率地进行热交换面板与电池单元之间的热交换,并且在电池单元的膨胀产生时也能够稳定维持高的热交换效率。
