 本发明的实施方式
为使本申请解决的技术问题、采用的技术方案和达到的技术效果更加清楚，下面将结合附图对本申请实施例的技术方案作进一步的详细描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部实施例。基于本申请中的实施例，本领域技术人员在没有做出创造性劳动的前提下所获得的所有其他实施例，都属于本申请保护的范围。
需要说明的是，当组件被称为“固定于”另一组件，它可以直接在另一组件上或者也可以存在居中的组件。当一个组件被认为是“连接”另一个组件，它可以是直接连接到另一组件或者可能同时存在居中组件。当一个组件被认为是“设置于”另一个组件，它可以是直接设置在另一个组件上或者可能同时存在居中组件。本文所使用的术语“垂直的”、“水平的”、“左”、“右”以及类似的表述只为了说明目的。
另需要说明，若本申请实施例中涉及“第一”、“第二”等的描述，则该“第一”、“第二”等的描述仅用于描述目的，而不能理解为指示或者暗示其相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括至少一个该特征。另外，各个实施例之间的技术方案可以相互结合，但必须是以本领域普通技术人员能够实现为基础，当技术方案的结合出现相互矛盾或无法实现时应当认为这种技术方案的结合不存在，也不在本申请要求的保护范围之内。
本申请提出一种电池模组，请参阅图1所示，电池模组包括外壳，多个方形电池10和水流通道。多个方形电池10安装于所述外壳内，避免电池10受到外部环境的碰撞和干扰。
所述外壳包括前端板81、第一侧板82、第二侧板83、后端板84和顶盖86，所述前端板81与后端板84平行，所述第一侧板82和第二侧板83平行，所述前端板81、第一侧板82、第二侧板83、后端板84相互紧固连接构成中空的腔体，盖上顶盖86之后罩在方形电池10外面，对方形电池10起保护作用。
方形电池10的结构如图2所示，所述方形电池10包括电池壳体、电解液（未示出）和电芯4，所述电芯4安装于所述电池壳体内，所述电池壳体包括盖板1、均热散热空腔2和底板3，所述均热散热空腔2上设置有第一腔室21、第二腔室22、第三腔室23和第四腔室24；所述底板3上设置有进水口和出水口，所述第一腔室21下部对应底板3上的第一进水口31和第一出水口32，所述第二腔室22下部对应底板3上的第二进水口33和第二出水口34，所述第三腔室和第四腔室内密封有传热工质。
在本实施例中，第一腔室21中包括第一隔断条211，第二腔室22中包括第二隔断条221，所述第一隔断条211和第二隔断条221与电池壳体的内外两层板紧密连接，起支撑电池壳体的作用，第一隔断条211和第二隔断条221靠近盖板1的一端有空缺，便于腔室内流体流动。当然在其他实施例中，第一腔室21和第二腔室22中也可以没有隔断条。
所述水流通道内里中空，呈长条状，一端封闭，另一端具有外接口。在本实施例中，所述水流通道包括第一水流通道5和第二水流通道6，第一水流通道5和第二水流通道6呈长条形，第一水流通道5上设置有第一外接口51、第一插口52和第二插口53，第二水流通道6上设置有第二外接口61、第三插口62和第四插口63，所述第一进水口31、第一出水口32分别对应第一插口52、第二插口53，所述第二进水口33、第二出水口34分别对应第三插口62、第四插口63，所述插口上具有密封圈，所述插头***所述进水口/出水口时，所述密封圈起密封防水作用。
在本实施例中，所述第一水流通道5和第二水流通道6设置在一块平板上，即承重板85，所述第一外接口51和第二外接口61分布在平板的同一侧，所述第一水流通道5和第二水流通道6设置在一块平板上，增加了模组的稳定性。
需要说明的是，所述第三腔室23和第四腔室24中填充的传热工质可以为气体或液体或者气体和液体的混合物，例如水、油、酒精等。填充有传热工质的电池外壳具有吸热、传热速率快和均温性好的特点。方形电池10的适宜工作温度在20-50℃之间，当方形电池10温度高于50℃，需要对方形电池10进行冷却，因此，冷媒从第一外接口51进入第一水流通道5，在压力作用下再通过第一插口52进入第一腔室21，流经第一隔断条211上的空缺处，最后从第二插口53中流出，同时，冷媒从第二外接口61进入第二水流通道6，在压力作用下再通过第三插口62进入第二腔室22，流经第二隔断条221上的空缺处，最后从第四插口63中流出，第三腔室23和第四腔室24吸收电芯4的热量均摊开来传导到第一腔室21和第二腔室22中，冷媒吸收第一腔室21和第二腔室22的热量后从流出，从而达到降温目的；当方形电池10温度低于20℃，就需要对电池进行加热，因此向第一腔室21和第二腔室22中通入热水，将热量传递给第三腔室23和第四腔室24，从而加热电池内部，达到升温的目的。
所述第三腔室23和第四腔室24内还设置有隔断条，所述隔断条与电池壳体10的内外板材紧密连接，起支撑电池壳体和保证腔室传热均匀性的作用，所述隔断条呈条状、丝带状或锯齿状中的一种或几种混合，在本实施例中，第三腔室23的第三隔断条231和第四腔室24的第四隔断条241均为条状。当然在其他实施例中，第三隔断条231和第四隔断条241也可以为其他形状，本申请不限于此。
请继续参阅图1，方形电池10呈一列插接在水流通道上，所述多个方形电池10之间设置有柔性绝缘导热层7，柔性绝缘导热层7夹设于相邻方形电池10之间，利于方形电池10之间进行传热，将热量分摊出去，同时柔性绝缘导热层7的柔性和绝缘性能够保护方形电池10免受碰撞和导电干扰。由于导热硅胶具有良好的导电性能和绝缘性能，因此通常采用导热硅胶作为柔性绝缘层的主要材料。柔性绝缘层5也可以采用其他柔性绝缘材料或具有绝缘性的柔性相变材料。
本申请还提出一种电池包，包括至少两个呈层叠或并排设置的所述电池模组。
本申请还提出一种储能***。该储能***包括上述电池包。由于该储能***采用了上述所有实施例的全部技术方案，因此至少具有上述实施例的技术方案所带来的所有有益效果，在此不再一一赘述。可以理解的是，该储能***可以为风电储能***、太阳能储能***或电网储能***等。
上述实施例仅例示性说明本申请的原理及其功效，而非用于限制本申请。任何熟悉此技术的人士皆可在不违背本申请的精神及范畴下，对上述实施例进行修改或改变。因此，举凡所述技术领域中具有通常知识者在未脱离本申请揭示的精神与技术思想下所完成的一切等效修饰或改变，仍应由本申请的权益要求所涵盖。
