技术领域
本申请实施例涉及电子元件制造技术领域，特别是涉及一种电池及用电设备。
 背景技术
作为交通工具的汽车，每天要排放大量的碳、氮、硫的氧化物、碳氢化合物、铅化物等多种大气污染物，是重要的大气污染发生源，对人体健康和生态环境带来严重的危害。而目前，以电能为动力的新能源汽车逐步占据汽车市场，从而缓解这些污染物对环境造成的污染。
新能源汽车为了保证其高续航能力，从而使用了能量密度较高的锂电池作为能源，锂电池是一类由锂金属或锂合金为正和/或负极材料、使用非水电解质溶液的电池。
而新能源汽车作为一台载人载具，其续航能力是目前市场亟需解决的关键问题。对于新能源汽车的电池而言，温度是影响电池输出功率的一大因素，在电池使用的过程中，常需要对电池的温度进行控制，如果电池温度不均匀，则电池的功率则会降低。
 技术问题
鉴于上述问题，本申请实施例旨在提供一种电池及用电设备，以改善目前电池温度不均匀，导致电池功率降低的现状。
 技术解决方案
第一方面，本申请提供了一种电池，包括外壳、换热模组以及电芯模组。其中外壳设置有容腔。换热模组包括第一换热组件，第一换热组件设置于容腔内。电芯模组设置于容腔内，电芯模组包括若干电芯，电芯与第一换热组件抵接，第一换热组件垂直于电芯叠置的方向设置。
本申请实施例的技术方案中，若干电芯均收容于容腔内，将第一换热组件垂直于电芯叠置的方向设置，并且电芯与第一换热组件抵接。从而使得每一电芯均能与第一换热组件进行热交换，从而使得电池内的每一电芯的温度相等，防止由于电池内部的温度不均匀导致电池的输出功率下降。
在一些实施例中，若干电芯呈阵列设置，任意相邻两列电芯之间具有间隙。间隙用于供第一换热组件设置，以使任意相邻两列电芯之间温度相等。
在一些实施例中，换热模组包括连接管，连接管设置于容腔。第一换热组件包括若干散热管和换热介质，若干散热管分别与连接管连通，换热介质填充于若干散热管内，并且若干散热管间隔设置，一散热管插接于一间隙，并且散热管分别与间隙两侧的两列电芯抵接。将换热介质通过连接管，传递至各个散热管内，从而使得插接于间隙的散热管可以与电芯进行热交换，从而使得各电芯之间温度相等。
在一些实施例中，散热管包括第一壁、第二壁和第三壁，第二壁和第三壁的一端分别与第一壁连接，一散热管中的第二壁和第三壁分别抵接于对应的间隙两侧的两列电芯。通过上述设计，使得同一散热管内的第二壁和第三壁温度相等，从而使得间隙两侧的两列电芯，所进行热交换的散热管温度相等。
在一些实施例中，第二壁的另一端和第三壁的另一端连接。这种设计方式的散热管容易安装，只需将散热管安装于间隙即可。
在一些实施例中，散热管的横截面的形状为三角形，所述散热管的横截面为垂直于第二壁和第三壁的截面。从而使得散热管可以与电芯的形状匹配，增大换热面积。
在一些实施例中，散热管包括第四壁，第二壁的另一端和第三壁的另一端分别与第四壁连接。这种设计的散热管与电芯的贴合会更加紧密，从而增大散热管与电芯的换热面积，提高换热效率。
在一些实施例中，第二壁和第三壁的形状均与电芯的形状相匹配，一散热管中的第二壁和第三壁分别与对应的间隙两侧的两列电芯贴合。从而使得散热管可以与电芯的形状匹配，增大换热面积。
在一些实施例中，散热管是由塑胶制备得到的。当电芯的温度过高，致使电池热失控时，由塑胶制备得到的散热管会溶解，从而使得散热管内的换热介质流出，并附着于电芯，从而直接进行热交换。
在一些实施例中，换热模组还包括第二换热组件，第二换热组件设置于容腔内，第二换热组件平行与电芯叠置的方向设置，电芯与第二换热组件抵接。通过设置第二换热组件，增加电芯的换热面积，从而提高换热效率。
在一些实施例中，第二换热组件的形状为波浪状，第二换热组件背离第一换热组件的一表面形成有若干第一收容槽，第二换热组件面向第一换热组件的另一表面形成有若干第二收容槽，一列电芯收容于一第一收容槽，另一列电芯收容于一第二收容槽内。通过设置波浪状第二换热组件，从而使得第二换热组件与电芯的形状相适配，增加电芯的换热面积，从而提高换热效率。
在一些实施例中，第一收容槽和第二收容槽的槽底均与电芯贴合。增大第二换热组件与电芯的换热面积，以提高换热效率。
第二方面，本申请实施例还提供一种用电设备，其包括上述电池。

目前，从市场形势的发展来看，动力电池的应用越加广泛。动力电池不仅被应用于水力、火力、风力和太阳能电站等储能电源系统，而且还被广泛应用于电动自行车、电动摩托车、电动汽车等电动交通工具，以及军事装备和航空航天等多个领域。随着动力电池应用领域的不断扩大，其市场的需求量也在不断地扩增。
对于动力电池而言，本发明人注意到，目前大多数动力电池内，都是通过化学反应进行电能的输入和输出。对于动力电池而言，动力电池在工作的过程中，动力电池内部的温度容易产生变化，而动力电池内一般包括多组电芯。当动力电池内部的电芯温度不相等时，动力电池的最大输入功率和最大输出功率会根据温度最低的电芯而设定。其原因是，温度最低的电芯内部的化学反应速度低于相对温度较高的电芯内部的化学反应速度，从而使得温度最低的电芯的输入功率和输出功率相对较低，为了防止动力电池由于无法共计足够的电能导致设备损坏，故动力电池的最大输入功率和最大输出功率会根据温度最低的电芯而设定。
本申请实施例公开的电池可以但不限用于车辆、船舶或飞行器等用电装置中。可以使用具备本申请公开的电池、电池等组成该用电装置的电源系统，这样，有利于缓解电池内部电芯温度不均匀，导致限制电池的最大输入功率和最大输出功率的现状。
本申请实施例提供一种使用电池作为电源的用电装置，用电装置可以为但不限于手机、平板、笔记本电脑、电动玩具、电动工具、电瓶车、电动汽车、轮船、航天器等等。其中，电动玩具可以包括固定式或移动式的电动玩具，例如，游戏机、电动汽车玩具、电动轮船玩具和电动飞机玩具等等，航天器可以包括飞机、火箭、航天飞机和宇宙飞船等等。
以下实施例为了方便说明，以本申请一实施例的一种用电装置为车辆1000为例进行说明。
请参阅图1，图1为本申请一些实施例提供的车辆1000的结构示意图。车辆1000可以为燃油汽车、燃气汽车或新能源汽车，新能源汽车可以是纯电动汽车、混合动力汽车或增程式汽车等。车辆1000的内部设置有电池100，电池100可以设置在车辆1000的底部或头部或尾部。电池100可以用于车辆1000的供电，例如，电池100可以作为车辆1000的操作电源。车辆1000还可以包括控制器200和马达300，控制器200用来控制电池100为马达300供电，例如，用于车辆1000的启动、导航和行驶时的工作用电需求。
在本申请一些实施例中，电池100不仅可以作为车辆1000的操作电源，还可以作为车辆1000的驱动电源，代替或部分地代替燃油或天然气为车辆1000提供驱动动力。
请参阅图2和图3，其分别示出了本申请其中一实施例提供的电池100的立体图和本申请其中一实施例提供的电池100的分解图。电池100包括外壳10、换热模组20和电芯模组30。外壳10设有容腔11，换热模组20包括第一换热组件21，第一换热组件21和电芯模组30均设置于容腔11内。电芯模组30包括若干电芯31，电芯31与第一换热组件21抵接，第一换热组件21垂直于电芯31叠置的方向X设置。可以理解的是，请参阅图3，本申请实施例中的垂直于电芯31叠置的方向X为Z方向，而Y方向为电芯31延伸的方向。
通过这种设计，当若干电芯31叠置收容于容腔11内时，为了使得相邻的两电芯31的温度相同，将第一换热组件21垂直于电芯31叠置的方向X设置，并且第一换热组件21与电芯31抵接，从而使得两相邻的电芯31与同一第一换热组件21抵接，以使每一电芯31的温度相等。以缓解电池100内部电芯31温度不均匀，导致限制电池100的最大输入功率和最大输出功率的现状。
在此需要说明的是，电芯31叠置的方向X为X方向。
在本申请实施例中，如图3至图5所示，若干电芯31呈阵列设置，任意相邻两列电芯31之间具有间隙40。通过设置间隙40，给第一换热组件21提供安装的空间，在两相邻电芯31温度差较大的情况下，一方面可以防止两相邻电芯31直接接触而发生危险，另一方面防止两相邻电芯31之间，相互影响化学反应速率。
在此需要说明的是，若干电芯31阵列设置，以形成多列电芯31，多列电芯31包括沿X方向（电芯31叠置的方向X）依次分布的至少两列电芯31。相邻两列电芯31之间具有间隙40，是指沿电芯31叠置的方向X相邻的两列电芯31之间具有间隙40。
对于上述第一换热组件21，请参阅图2至图4，其分别示出了本申请其中一实施例提供的电池100的立体图、本申请其中一实施例提供的电池100的分解图以及本申请提供的图2的A面的截面图。换热模组20还包括连接管23，连接管23设置于容腔11，并且连接管23沿电芯31叠置的方向X延伸，第一换热组件21包括若干散热管211和换热介质（图中未示出），若干散热管211分别与连接管23连通，换热介质填充于若干散热管211内，并且若干散热管211间隔设置，一散热管211插接于一间隙40，并且散热管211分别与间隙40两侧的两列电芯31抵接。
通过将若干散热管211与同一连接管23连接，以使每一散热管211内的温度均与连接管23内的温度相等，从而使得每一散热管211的温度相等，进一步使得与散热管211抵接的电芯31，在与散热管211完成热交换后，电芯31处于稳定状态下的温度相等，以达到电池100内部电芯31温度相等，提高最大输入功率和最大输出功率的目的。并且，通过在散热管211内设置换热介质，以提高第一换热组件21的换热效率。在一些实施例中，换热介质包括但不限于水、乙二醇等介质。在一些实施例中，上述连接管23还可以与车辆1000的空调系统的换热剂循环回路（图未示）相连通，换热剂循环回路由两个并联支路（图未示）构成，一个用于车内空间的热交换，另一个用于电池100的热交换，从而提高电池100内的热交换效率。
在此需要说明的是，如图3至图5所示，间隙40两侧的两列电芯31沿X方向依次分布，也即是沿电芯31叠置的方向X依次分布，以使散热管211与间隙40两侧的电芯31沿X方向依次分布，进而使得散热管211垂直于电芯31叠置的方向设置。
对于上述散热管211，请参阅图5，其示出了本申请提供的图4的B部放大图，并结合其他附图。散热管211包括第一壁2111、第二壁2112和第三壁2113，第二壁2112和第三壁2113的一端分别与第一壁2111连接，一散热管211中的第二壁2112和第三壁2113分别抵接于对应的间隙40两侧的两列电芯31。抵接于第二壁2112和第三壁2113的两列电芯31均与同一散热管211内的换热介质进行热交换，从而使得两列电芯31温度相等。
在一些实施例中，请参阅图6和图7，其分别示出了本申请提供的图2的另一种实施例的截面图和本申请提供的图6的C部放大图。第二壁2112的另一端和第三壁2113的另一端连接。这种设计方式的散热管211容易安装，只需将散热管211安装于间隙40即可。
在一些实现方式中，请参阅图6和图7，其分别示出了本申请提供的图2的另一种实施例的截面图和本申请提供的图6的C部放大图。第二壁2112的另一端和第三壁2113的另一端连接。散热管211的横截面的形状为三角形，其中，散热管211的横截面为垂直于第二壁2112和第三壁2113的截面。这种设计方式的散热管211容易安装，只需将散热管211安装于间隙40即可。
在另一些实现方式中，在散热管211的横截面中，第一壁2111呈弧线形，而非图7中示意的直线形，如此使得散热管211的横截面的形状为扇形。当然，在又一些实现方式中，在散热管211的横截面中，第一壁2111还可以为波浪状等。
在一些实施例中，请参阅图5，并结合其他附图。散热管211包括第四壁2114，第二壁2112的另一端和第三壁2113的另一端分别与第四壁2114连接。这种设计的散热管211与电芯31的贴合会更加紧密，从而增大散热管211与电芯31的换热面积，提高换热效率。
在一些实施例中，请参阅图5，并结合其他附图。散热管211包括第四壁2114，第二壁2112的另一端和第三壁2113的另一端分别与第四壁2114连接。并且，第二壁2112和第三壁2113的形状均与电芯31的形状相匹配，一散热管211中的第二壁2112和第三壁2113分别与对应的间隙40两侧的两列电芯31贴合。这种设计的散热管211与电芯31的贴合会更加紧密，从而增大散热管211与电芯31的换热面积，提高换热效率。
在本申请实施例中，散热管211是由塑胶制备得到的，从而使得当电芯31的温度过高时，电芯31将散热管211融化，从而使得散热管211内的换热介质泄露，并且换热介质直接附着于电芯31表面，进一步进行热交换。并且由于电池100包括外壳10，所以换热介质不会因为外泄至电池100之外污染环境。在一些实施例中，散热管211还可以由金属制备得到，利用金属本身的物理属性，从而提升换热效率。
在本申请实施例中，请参阅图5，并结合其他附图。换热模组20还包括第二换热组件22。第二换热组件22设置于容腔11内，第二换热组件22平行于电芯31叠置的方向X设置，电芯31与第二换热组件22抵接。即，电芯31沿垂直于电芯31叠置的方向X上设有第二换热组件22，电芯31沿平行于电芯31叠置的方向X上设有第一换热组件21，从而使得每一电芯31均与第一换热组件21和第二换热组件22抵接，便于电芯31与第一换热组件21和第二换热组件22的热交换。
可以理解的是，第一换热组件21垂直于电芯31叠置的方向X设置，是指电芯31沿平行于电芯31叠置的方向X上设有第一换热组件21，以使该电芯31和第一换热组件21沿电芯31叠置的方向X依次分布。第二换热组件22平行于电芯31叠置的方向X设置，是指电芯31沿垂直于电芯31叠置的方向X上设有第二换热组件22，以使该电芯31和第二换热组件22沿垂直于电芯31的叠置方向X依次分布，也即是沿Z方向依次分布。
在本申请实施例中，请参阅图5，并结合其他附图。第二换热组件22的形状为波浪状，第二换热组件22背离第一换热组件21的一表面形成有若干第一收容槽221，第二换热组件22面向第一换热组件21的一表面形成有若干第二收容槽222，一列电芯31收容于一第一收容槽221，另一列电芯31收容于一第二收容槽222内。在一些实施例中，第一收容槽221和第二收容槽222的槽底与电芯31贴合，例如当电芯31为圆柱形的电芯31时，第一收容槽221和第二收容槽222的槽体的截面呈弧状，第一收容槽221和第二收容槽222的槽体的截面为垂直于电芯31轴向的截面。这种设计，一方面增大第二换热组件22与电芯31的换热面积，以提高换热效率；另一方面，波浪状的第二换热组件22由于设置了第一收容槽221和第二收容槽222，则有利于安装电芯31，还增加了电池100内部的结构强度，减少了震动对电芯31的影响，提升了电池100的稳定性。可以理解的是，在本申请的一些实施例中，收容于第一收容槽221和第二收容槽222的两列电芯31之间均设有，垂直于电芯31叠置的方向X的第一换热组件21，从而提高换热效率。具体地，收容于第一收容槽221的两列电芯31之间设有第一换热组件21，收容于第二收容槽222的两列电芯31之间也设有第一换热组件21。
可以理解的是，若干电芯31阵列设置，以形成多列电芯31，多列电芯31还包括沿Z方向（垂直于电芯31叠置的方向X）依次分布的至少两列电芯31。沿Z方向相邻的两列电芯31中，其中一列收容于第二换热组件22的第一收容槽221，另一列收容于第二收容槽222。
根据本申请的一些实施例，本申请还提供了一种用电设备，包括以上任一方案所述的电池100，并且电池100用于为用电设备提供电能。
用电设备可以是前述任意应用电池100的装置或系统。
根据本申请的一些实施例，参见图2至图5，本申请提供了一种电池100，包括外壳10、换热模组20以及电芯模组30，其中外壳10设置有容腔11。换热模组20包括第一换热组件21，第一换热组件21设置于容腔11内。电芯模组30设置于容腔11内，电芯模组30包括若干电芯31，电芯31与第一换热组件21抵接，第一换热组件21垂直于电芯31叠置的方向X设置。第一换热组件21包括连接管23、与连接管23连接的若干散热管211以及填充于散热管211的换热介质。在本申请实施例中，第一换热组件21包括两个连接管23，每一散热管211的两端均与两连接管23连接。其中散热管211包括第一壁2111、第二壁2112、第三壁2113和第四壁2114，第二壁2112的一端和第三壁2113的一端分别与第一壁2111连接，第二壁2112的另一端和第三壁2113的另一端分别与第四壁2114连接。第二壁2112和第三壁2113的形状均与电芯31的形状相匹配，一散热管211中的第二壁2112和第三壁2113分别与对应的间隙40两侧的两列电芯31贴合。并且换热模组20还包括呈波浪状的第二换热组件22，以使电芯31沿垂直于电芯31叠置的方向X上设有第二换热组件22，电芯31沿平行于电芯31叠置的方向X上设有第一换热组件21，从而使得每一电芯31均与第一换热组件21和第二换热组件22抵接，便于电芯31与第一换热组件21和第二换热组件22的热交换。同时，在第二换热组件22背离所述第一换热组件21的一侧还设有另一列电芯31。从而使得位于第二换热组件22两侧的电芯31均与第二换热组件22进行热交换，从而使得两列电芯31的温度相等，从而减少温度对电池100的最大输入功率和最大输出功率的限制。
根据本申请的另一些实施例，参见图4，并结合其他附图。在上述实施例的情况下，可以在第二换热组件22的两侧均设有第一换热组件21，从而使得位于第二换热组件22的两侧的电芯31均可以与至少一个第一换热组件21和至少一个第二换热组件22抵接，从而使得每一电芯31的温度相等，从而减少温度对电池100的最大输入功率和最大输出功率的限制。
根据本申请的又一些实施例，参见图6至7，并结合其他附图。上述散热管211的横截面的形状为三角形，散热管211的横截面为垂直于第二壁2112和第三壁2113的截面，这种设计方式的散热管211便于安装，且同样可以使得每一电芯31的温度相等，从而减少温度对电池100的最大输入功率和最大输入功率的影响。
最后应说明的是：以上各实施例仅用以说明本申请的技术方案，而非对其限制；尽管参照前述各实施例对本申请进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分或者全部技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本申请各实施例技术方案的范围，其均应涵盖在本申请的权利要求和说明书的范围当中。尤其是，只要不存在结构冲突，各个实施例中所提到的各项技术特征均可以任意方式组合起来。本申请并不局限于文中公开的特定实施例，而是包括落入权利要求的范围内的所有技术方案。最大输出功率的限制。
