具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
需要说明的是，当组件被称为“固定于”另一个组件，它可以直接在另一个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个组件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”以及类似的表述只是为了说明的目的。
除非另有定义，本文所使用的所有的技术和科学术语与属于本发明的技术领域的技术人员通常理解的含义相同。本文中在本发明的说明书中所使用的术语只是为了描述具体的实施例的目的，不是旨在于限制本发明。本文所使用的术语“及／或”包括一个或多个相关的所列项目的任意的和所有的组合。
下面结合附图，对本发明的一些实施方式作详细说明。在不冲突的情况下，下述的实施例及实施例中的特征可以相互组合。
请参阅图1，本发明较佳实施方式提供一种电池100，包括壳体11及多个电芯13。所述壳体11设置有容纳腔111，用以收容所述多个电芯13。
在本实施例中，所述壳体11为两端开口的筒体结构，其包括第一壳体113及第二壳体115。所述第一壳体113为U型结构，包括底板116以及分别从所述底板116的相对两端朝向底板116的同一侧垂直延伸的两个侧板117。所述第二壳体115扣合在所述第一壳体113上，以与所述第一壳体113共同围成所述容纳腔111。具体的，所述第二壳体115为U型结构，包括底部118以及分别从所述底部118的相对两端朝向底部118的同一侧垂直延伸的两个侧部119。其中所述侧部119分别扣合于相应的侧板117上，所述底部118与所述底板116相对设置，进而构成所述容纳腔111。
请一并参阅图2，所述多个电芯13收容于所述容纳腔111内，且层叠排布设置。所述多个电芯13之间均间隔设置，进而形成多个空气通道131。可以理解，所述多个电芯13中的每个电芯13的两端均设置有至少一间隔部133，进而使得所述多个电芯13间隔设置，以形成所述多个空气通道131。在本实施例中，所述间隔部133可以为绝缘体，例如泡棉。当然，在其他实施例中，所述间隔部133还可以为导热垫片等其他导热体。
所述壳体11上还设置有导风孔112。在本实施例中，所述导风孔112的数量为多个。具体的，其中一部分所述导风孔112分别布设于所述侧板117，且呈与所述底板116相互平行设置的长槽状，作为出风孔。所述壳体11靠近所述电芯13的底部的开口形成一导风孔，并且作为进风孔。所述出风孔及进风孔均与所述空气通道131相连通，用以使得所述壳体11外的气流能够通过进风孔进入所述容纳腔111，以形成空气对流而吹向所述多个电芯13，并流经所述空气通道131，最后从出风孔流出，从而带走所述多个电芯13之间的热空气。
在其他实施中，所述多个导风孔112中的至少两个分别为进风孔及出风孔，例如，设置于图1中所述底板116右侧的侧板117上的导风孔112为进风孔，设置于图1中所述底板116左侧的侧板117上的导风孔112为出风孔。如此，所述壳体11外的气流可从所述底板116右侧的侧板117上的导风孔112（即进风孔）进入到所述壳体11内，经过所述空气通道131后，从所述底板116左侧的侧板117上的导风孔112（即出风孔）流出。
可以理解，在其他实施例中，所述壳体11的至少一个内壁与所述多个电芯13直接或间接面接触，以传导所述多个电芯13产生的热量。因此，当所述壳体11外的气流从所述进风孔进入到所述壳体11内，并经过所述空气通道131后，从所述出风孔流出时，所述壳体11外的气流还可带走所述多个电芯13通过热传导至所述壳体11上的热量。
可以理解，所述导风孔112的形状不局限于上述所述的长槽状，其还可以为密布的圆孔状或其他形状，仅需确保所述导风孔112与所述多个空气通道131相连通，并使得所述壳体11外的气流可通过一部分导风孔112进入壳体11内部，再从另外一部分导风孔112流出，即产生空气对流。
可以理解，所述壳体11的材料可以采用导热性较好的材料制成。例如，壳体11的材料可以为铝，铝合金，铜，铜合金，银，银合金，石墨烯，碳纳米管。
所述壳体11的板体的厚度可以根据实际需求来设计，优选地，所述壳体11的板体的厚度可以为0.05-5毫米，例如，0.05毫米，0.15毫米，0.25毫米，0.35毫米，0.45毫米，0.55毫米，0.65毫米，0.70毫米，0.75毫米，0.85毫米，0.95毫米，1.05毫米，1.55毫米，2.05毫米，2.55毫米，3.05毫米，3.55毫米，4.05毫米，4.55毫米，5.0毫米。
可以理解，在其他实施例中，所述壳体11的形状不局限于上述所述的两端开口的筒体结构，其具体结构还可以根据不同需求来设计。例如，所述壳体11为一端开口的盒体结构或者封闭的盒体结构等等。如此，所述进风孔及所述出风孔不局限于设置于所述壳体11的相对两侧，其还可设置于所述壳体11的相邻两侧。
请一并参阅图3，可以理解，在其他实施例中，所述电池100还可包括至少一个导热架15，所述至少一个导热架15安装在所述容纳腔111内。其中，所述导热架15与壳体11的容纳腔111的内壁导热连接，并且导热架15能够与电芯13接触，以使得所述电芯13的热量可更快地通过所述导热架15传导至壳体11上，进而更好的降低温升。
在本实施例中，所述导热架15包括用于与电芯13面接触的主板体151及分别从所述主板体151的相对两端朝向主板体151的同一侧垂直延伸的两个抵接板153。进一步的，所述主板体151的尺寸与电芯13对应的尺寸相当，以使得所述主板体151与电芯13面接触。由于主板体151与所述电芯13面接触，如此可有效增大所述电芯13与导热架15的接触面积，从而进一步提高该电池100的散热效率。
可以理解，所述导热架15与所述壳体11的接触方式可以采用不同方式，例如，多点接触，线接触，面接触。在本实施例中，导热架15与壳体11的容纳腔111的内壁的连接处分别设有抵接面，以使导热架15与收纳腔111的内壁的连接处形成面接触。具体地，所述导热架15的抵接面设于导热架15的抵接板153上，所述壳体11的抵接面设于所述壳体11的侧板117上。
可以理解，当所述电池100设置所述导热架15时，所述抵接板153的高度与所述电芯13的高度相当或低于所述电芯13的高度。所述间隔部133设置于所述主体板151与相邻的电芯13之间。如此，以确保所述多个电芯13中相邻的电芯13之间可形成所述空气通道131。
可以理解，请再次参阅图1，在其他实施例中，所述电池100还包括外壳17。所述外壳17包括第一外壳171及第二外壳173。所述第一外壳171与第二外壳173相互扣合在一起，并共同套设在所述壳体11外，以保护所述壳体11。另外，所述外壳17还开设有外露所述壳体11的至少局部的散热窗口175。
可以理解，在其他实施例中，所述电池100还包括连接板18。所述多个电芯13的一端可固定于所述连接板18上,且与所述连接板18电连接，以通过所述连接板18固定于所述壳体11的容纳腔111内。所述连接板18可以为极耳板或控制电路板。所述连接板18可设置于所述壳体11的顶部。对应的，所述进风孔可设置于所述壳体111的底部，且所述出风孔的数量为至少两个，其分别位于所述壳体11的两个相对侧面。所述两个侧面位于所述壳体11的顶部与所述底部之间。如此，当壳体11外的气流通过所述壳体11的底部处的进风孔进入所述壳体11内时，可吹向所述多个电芯13以及位于所述壳体11顶部的连接板18，再通过位于所述壳体11两侧的出风孔流出，以形成空气对流，进而对所述连接板18进行良好散热。
请一并参阅图4，使用该电池100时，每一个电芯13产生的热量将通过热辐射作用辐射至周围的空气中，其中所述多个电芯13之间的空气通道131聚集大量的热量。同时，所述多个电芯13与壳体11接触的部分通过热传导作用将热量传导至壳体11上。如此，壳体11外部的气流可通过壳体11上的部分导风孔112穿过所述空气通道131，并从另外的导风孔112导出，从而带走热量。同时，所述壳体11外部的气流也可通过电池100的壳体11表面带走热量，从而加速电池100的降温，并实现不同电芯13的温度一致。
请参阅图5，本发明的实施方式还提供一种无人飞行器200，该无人飞行器200至少包括机身201、螺旋桨202以及所述电池100。所述机身201上设有电池仓203。所述电池100设于电池仓203内。外界的风源可产生空气对流，以通过其中一部分导风孔112吹向电池仓203内的所述多个电芯13，并穿过所述多个电芯13之间的空气通道131，并从另外一部分导风孔112流出，从而带走热量，同时所述风源产生的气流还通过所述壳体11的表面带走热量。
具体地，所述机身201包括机体2011以及中空的机臂2013。所述机臂2013与所述机体2011固定连接，且用以承载所述螺旋桨202。所述电池仓203设于所述机身201的机体2011内。所述机臂2013的内腔与电池仓203的内腔相连通。进一步地，所述无人飞行器200的机身201上还开设有进风口205及出风口207。所述进风口205设于所述机体2011上，所述出风口207设置于所述机臂2013上。所述进风口205与所述出风口207均与所述电池仓203的内腔相连通，其用于使电池仓203内外的空气能够形成对流，其中所述进风口205用于吸入外界的风源产生的气流，并且所述气流能够经所述电池仓203后从所述出风口207流出。
可以理解，在其中一个实施例中，所述空气对流的风源可直接来自于所述螺旋桨202，所述螺旋桨202产生的气流通过风道导入至所述电池100表面。具体的，所述螺旋桨202产生的气流通过所述进风口205导入所述电池100内部，并通过所述出风口207流出。
可以理解，在另外的实施例中，所述空气对流的风源可来自于独立安装的风扇（图未示），所述独立的风扇安装于所述无人飞行器200的机体2011内或电池100上。请一并参阅图6，当所述空气对流的风源来自于独立安装的风扇时，该风扇可用于专门对电池100提供对流电源，进而提高散热效果。
上述电池100及具有该电池100的无人飞行器200设置有壳体11，该壳体11上设置有相应的导风孔112。该导风孔112与所述多个电芯13之间的空气通道131相连通，进而形成空气对流，以使得外界的气流可通过部分导风孔112进入所述壳体11内，并吹向所述多个电芯13，再流经所述多个空气通道131，进而从另外一部分导风孔112流出，以带走所述多个电芯13之间的热空气。另外，所述多个电芯13还与所述壳体11进行导热接触，进而将所述电芯13产生的热量传导至所述壳体11，从而有效降低电池100温升，其散热效果较佳，且可有效提高该电池100的使用寿命。上述电池100无需配备动力系统，从而避免增加额外的功耗，并且使得上述电池100及具有该电池100的无人飞行器200体积较小，重量较轻，成本较低。
以上实施方式仅用以说明本发明的技术方案而非限制，尽管参照以上较佳实施方式对本发明进行了详细说明，本领域的普通技术人员应当理解，可以对本发明的技术方案进行修改或等同替换都不应脱离本发明技术方案的精神和范围。本领域技术人员还可在本发明精神内做其它变化等用在本发明的设计，只要其不偏离本发明的技术效果均可。这些依据本发明精神所做的变化，都应包含在本发明所要求保护的范围之内。
