下面将结合本申请实施例中的附图，对本申请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申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，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，都属于本申请保护的范围。
下面结合附图，对本申请进行详细说明。在不冲突的情况下，下述的实施例及实施方式中的特征可以相互组合。
请参阅图1至图4，图1是本申请一示例性实施例示出的一种电池的一角度结构示意图；图2是本申请一示例性实施例示出的一种电池的另一角度结构示意图；图3是本申请一示例性实施例示出的一种电池的爆炸图；图4是本申请一示例性实施例示出的一种电池的一角度剖面示意图。本申请实施例的电池10包括壳体1、收容于壳体1内的电芯2、以及盖于壳体1的盖体3。
其中，该电芯2与壳体1之间形成有散热风道11，盖体3上设有与散 热风道11连通的入风口31和出风口32，如此以使气流从入风口31流入电池10内并经过散热风道11流向出风口32，以将电池10内的热量带出，从而实现为电池10散热。此外，由于使用过程中即可以通过散热风道11为电池10散热，可以在电池10停止使用后即可以为电池10进行充电，无需等到电池10降温到充电截止温度。
在一些实施例中，该盖体3内设有第一气流通道33，第一气流通道33弯曲设置并连通入风口31和散热风道11。在另一些实施例中，该盖体3内设有第二气流通道35，第二气流通道35弯曲设置并连通出风口32和散热风道11。在本申请的实施例中，第一气流通道33弯曲设置并连通入风口31和散热风道11，第二气流通道35弯曲设置并连通出风口32和散热风道11，通过将第一气流通道33和第二气流通道35均弯曲设置，如此可以有效避免水进入电池10内。
如图1至图6所示，该盖体3为盒体结构，且安装在壳体1的顶部。本申请的电池10还包括设置于盖体3内的控制电路板363，该控制电路板363用于管理和控制电池10的电芯2进行充放电。在一些实施例中，电芯2预先装配于壳体1内，在盖体3盖于壳体1时，该控制电路板363电性连接于电芯2。在另一些实施例中，该电芯2也可以预先装配于盖体3并电性连接于控制电路板363，而后在装配于壳体1内。
其中，该盖体3朝壳体1的一侧面设置入风口31和出风口32。由于盖体3安装在壳体1的顶部，且该入风口31和出风口32设置在盖体3朝向壳体1的一侧，即盖体3朝壳体1的一侧面为盖体3的下侧面，因此该入风口31和出风口32均朝下，如此以使水不易于流入盖体3内。本申请的实施例中，该入风口31和出风口32设置在盖体3朝向壳体1的一侧，并配合第一气流通道33和第二气流通道35弯曲设置的特征，满足电池10具有散热通道的条件下，可以进一步可以起到防水的作用，避免水进入到电池10的散热通道内。
在一些实施例中，如图3至图8所示，该壳体1具有开口，盖体3朝 向壳体1的一侧包括遮盖面361和非遮盖面362。其中，该遮盖面361遮盖开口，入风口31和出风口32设置在非遮盖面362。该实施例中，非遮盖面362位于遮盖面361的外围，入风口31和出风口32分设于壳体1的相对两侧。其中，该入风口31为壳体1的长度方向的长条形开口。
在一些实施例中，如图3和图4所示，该盖体3包括上盖部37以及与上盖部37相对设置的下盖部36。控制电路板363位于上盖部37与下盖部36构成的容置空间内，该入风口31和出风口32开设在下盖部36。该上盖部37设有用于控制电池10的操作按键，操作按键的功能包括如下至少一种：电源开关、控制显示剩余电量、控制显示当前电池10温度。
进一步地，如图3至图6所示，该盖体3上设有握持部34，该握持部34用以辅助使用者插拔电池10等操作。在一些实施例中，该握持部34为设置在盖体3上的握持把手，该握持把手位于盖体3的非遮盖面362。该握持把手由盖体3长度方向的一侧向外延伸出，握持部34包括握持孔341，该握持孔341贯穿盖体3的上盖部37和下盖部36。
该实施例中，入风口31包括两个，两个入风口31分设于握持部34在壳体1长度方向上的两侧，即两个入风口31位于握持孔341的两侧。在盖体3上设置两个入风口31，可以提高入风量，从而提高散热效率。此外，将入风口31设置在握持部34在壳体1长度方向上的两侧，以使该入风口31的设置可以有效利用盖体3上的空间，不需要额外占用空间。当然，在其他实施例中，也可以将出风口32设置在握持部34的旁侧。
如图1至图8所示，该第一气流通道33包括第一通道331、以及至少一个第二通道332。其中，第二通道332连通在入风口31与第一通道331之间，第一通道331与散热风道11连通。该第二通道332用以将气流从入风口31引导向第一通道331并由第一通道331流向散热风道11。其中，该第一通道331的延伸方向平行于壳体1的长度方向。该实施例中，入风口31和出风口32分设于壳体1宽度方向的相对两侧，如此以使散热风道11可以覆盖电芯2在壳体1的长度方向的区域，增加了散热风道11的整 体尺寸，可以提高电池10的散热效率。
在一些实施例中，第二通道332包括至少两个，至少两个第二通道332分散延伸向第一通道331。其中，该第二通道332包括喇叭状的导向腔，导向腔连通第一通道331，以将从入风口31流入的气流导入第一通道331。在本申请的图示中，该第二通道332为两个，两个第二通道332呈喇叭状延伸向第一通道331，如此设置以使气流可以分散地流入第一通道331内，从而使第一通道331内流入的气流可以相对均匀地分布，进而使气流相对均匀地流入散热风道11内，有利于为电芯2进行整体散热。在其他实施例中，该第二通道332可以为多个，多个第二通道332可以均匀地分散延伸向第一通道331。
其中，该第一气流通道33在气流方向上的截面呈n型，该种结构设置可以有效避免水进入。在第一气流通道33包括至少两个第二通道332时，每个第二通道332与第一通道331配合在气流方向上的截面均呈n型。
再次参照图1至图8，本申请的壳体1包括底壁12以及与底壁12配合围合成腔体的侧壁13，该腔体用以收容电芯2。其中，该侧壁13和/或底壁12设有第一配合部14，电芯2上设有与第一配合部14适配的第二配合部21，通过第一配合部14与第二配合部21的装配，以使电芯2安装于壳体1内。在一些实施例中，该第一配合部14为设置于壳体1上的筋条，第二配合部21为设置于电芯2上的凹槽。在另一些实施例中，第一配合部14为设置于壳体1上的凹槽，第二配合部21为设置于电芯2上的筋条。本申请的图示中，以该第一配合部14为设置于壳体1上的筋条，第二配合部21为设置于电芯2上的凹槽为例进行展示。其中，该筋条的凸起高度范围为4mm-5mm。
在一些实施例中，至少一对相对的侧壁13和底壁12分别设有第一配合部14，位于底壁12上的第一配合部14与位于至少一对相对的侧壁13上的第一配合部14衔接。该电芯2安装在壳体1内时，与设置有第一配合部14的侧壁13、底壁12之间具有间隙，间隙形成至少两个间隔的散热子 风道110。该实施例中，位于相对侧壁13和底壁12的第一配合部14与电芯2的第二配合部21配合装配后，将散热风道11分隔为两个间隔的散热子风道110。
在另一些实施例中，至少一对相对的侧壁13、底壁12上分别设有多个间隔的第一配合部14，电芯2上设有与第一配合部14一一对应的第二配合部21。相对的侧壁13、底壁12上分别设有多个间隔的第一配合部14，该多个第一配合部14与电芯2上的第二配合部21分别配合装配，将壳体1内的散热风道11分隔为多个尺寸较小的散热子风道110。通过设置多个散热子风道110，可以有效引导气流沿散热子风道110快速流动，避免因散热风道11过大而导致气流串扰，从而影响气流的流出速度。
在该些实施例中，该散热子风道110呈“U”型，即分隔为多个尺寸较小的散热子风道110呈“U”型。其中，每一个散热子风道110分别与第一气流通道33、第二气流通道35连通，如此以使每一个散热风道11可以进行独立散热。
进一步地，为了加快电芯2的散热效率，该电芯2上设有散热翅片，散热翅片位于散热风道11内。此外，为了进一步保证电池10的安全性，该电芯2的表面设有防水层，从而进一步地提高电池10的防水性。
在一些实施例中，散热风道11包括相对的两个侧壁13与电芯2之间分别构成的第一风道111和第二风道112、以及底壁12与电芯2之间构成的第三风道113。第一风道111和第二风道112分别与第三风道113连通，第一气流通道33与第一风道111连通，第二气流通道35与第二风道112连通。该散热风道整体呈“U”型，该三个风道的设置可以为电池10的三个侧面进行散热。其中，该第一风道111和第二风道112位于电芯2在壳体1的长度方向的两侧，第三风道113位于电芯2在壳体1长度方向的底面，如此以使散热风道11的总体面积达到最大，有利于为电芯2散热，提高电池10的散热效率。
结合上述实施例，在多个第一配合部14与电芯2上的第二配合部21 分别配合装配，将壳体1内的散热风道11分隔为多个尺寸较小的散热子风道110时，相对的两个侧壁13与电芯2之间分别构成多个第一风道111和第二风道112，底壁12与电芯2之间构成多个第三风道113，如此以将“U”型的散热风道11分割为多个并排设置的散热子风道110。
其中，在侧壁13与电芯2的相对方向上，第一风道111的间距为30mm-40mm。在底壁12与电芯2的相对方向上，第二风道112的间距为30mm-40mm。
本申请实施例电池10的电芯2与壳体1之间形成散热风道11，盖体3内设有第一气流通道33和第二气流通道35，第一气流通道33弯曲设置并连通入风口31和散热风道11，第二气流通道35弯曲设置并连通出风口32和散热风道11，如此以使电池10内形成与外界连通的散热风道11，通过气流流经电芯2以将电池10内的热量带走，从而降低电池10的工作温度，提高电池10的工作效率，提高电池10的性能及寿命。此外，通过第一气流通道33和第二气流通道35弯曲设置还可以为电池10起到防水的作用。
如图9和图10，结合图1至图8，在本申请的实施例的又一方面，还提供了一种无人机100，该无人机100包括机架20、多个旋翼装置30以及电池10。该无人机100可以为农业植保机。该电池10的具体结构如上述各个实施例所示，在此不再赘述。当然，在其他实施例中，该电池10还可以应用到新能源汽车、机器人等可移动设备中。
其中，机架20包括中心体201以及与中心体201连接的多个机臂202。多个旋翼装置30分别安装在多个机臂202上。每个旋翼装置30包括电机301以及安装在电机301上的螺旋桨302。电池10安装于中心体201上。
现在农业植保机一般具有较大的载重量，所以在工作的时候，工作电流很大，由于电池本身具有一定的内阻，因此在大电流工况下工作时会产生很高的热量。当电池温度较高时，电池本身性能会下降，而且长时间在温度较高状态下工作会影响电池寿命。且在实际工作时，如果电池温度较高，则充电器无法给电池充电。
基于以上背景，本申请电池10内设有散热风道11，并将电池10的入风口31和出风口32朝下设置，多个旋翼装置30产生的气流能够从电池10的入风口31进入，从电池10的出风口32流出，从而为电池10散热。同时该电池10的入风口31和出风口32朝下设置有利于对电池10进行防水设置。进一步地，盖体3内设有第一气流通道33和第二气流通道35，第一气流通道33弯曲设置并连通入风口31和散热风道11，第二气流通道35弯曲设置并连通出风口32和散热风道11，通过第一气流通道33和第二气流通道35弯曲设置还可以为电池10起到防水的作用。
需要说明的是，在本文中，诸如第一和第二等之类的关系术语仅仅用来将一个实体或者操作与另一个实体或操作区分开来，而不一定要求或者暗示这些实体或操作之间存在任何这种实际的关系或者顺序。术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者设备不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物品或者设备所固有的要素。在没有更多限制的情况下，由语句“包括一个……”限定的要素，并不排除在包括所述要素的过程、方法、物品或者设备中还存在另外的相同要素。
