本申请涉及电池技术领域，特别是涉及一种热管理部件、电池及用电装置。
背景技术
节能减排是汽车产业可持续发展的关键，电动车辆由于其节能环保的优势成为汽车产业可持续发展的重要组成部分。对于电动车辆而言，电池技术又是关乎其发展的一项重要因素。
温度对于电池的性能有重要的影响，所以常规技术中的电池会设置热管理部件，用于对电池降温或在低温环境下对电池加热升温，使电池达到正常工作温度区间。然而，现有技术的热管理部件存在换热性能不均的问题，影响电池温度的均匀性。
发明内容
本申请提供一种热管理部件、电池及用电装置，该热管理部件能够有效提高换热均匀性，有利于提升电池的温度均匀性。
第一方面，本申请提供了一种热管理部件，包括：第一集流管，包括依次连通的第一进出液口、第一流道和第二流道，所述第一流道和所述第二流道均从所述第一集流管的第一端延伸至所述第一集流管的第二端，所述第一进出液口设置于所述第一端，所述第一流道的一端与所述第一进出液口连通，另一端与所述第二流道连通；第二集流管，与所述第一集流管相互平行且间隔设置，包括相互连通的第二进出液口和第三流道，所述第二进出液口设置于所述第二集流管的靠近所述第一进出液口的一端；多个换热管，并排设置于所述第一集流管和所述第二集流管之间，每个所述换热管的一端与所述第二流道连通，另一端与所述第三流道连通。
上述技术方案中，热管理部件包括间隔设置的第一集流管和第二集流管，以及多个并排设置于第一集流管和第二集流管之间的多个换热管，多个换热管通过第一集流管和第二集流管并联连通，在第一集流管设置并列的第一流道和第二流道，且第一流道和第二流道均从所述第一集流管的第一端延伸至所述第一集流管的第二端，同 时，第一进出液口设置于第一端与第一流道连通，第二流道与换热管连通，也就是说，第一集流管上的第一进出液口布置在远离换热管的一侧第一流道。第二进出液口与第一进出液口位于同一侧，第一进出液口和第二进出液口一个用于进液，一个用于出液。即，第一集流管可以用于进液集流管也可以用于出液集流管。
在本申请中，当第一集流管用于进液集流管时，流体经第一进出液口进入第一流道并沿第一流道向第二端流动，进入第二通道后再沿第二通道流动然后进入到每个换热管中，最终经第二集流管的第二进出液口排出；同样的，当第一集流管用于出液集流管时，则各换热管内的流体进入到第二流道后沿第一集流管的长度方向向第二端的流通，再从第二流道与第一流道的连通处折回，在第一流道内向第一端流通并经第一进出液口排出。
本申请的热管理部件通过在第一集流管内设置第一流道和第二流道，使得流体能够在进液集流体中或出液集流体中向远离第一进出液口和第二进出液口的一端分配，从而缓解靠近第一端的换热管流量大、靠近第二端的换热管流量小的问题，通过采用均衡流体流经每个换热管的路径长度的手段降低各换热管之间的流量差，提高换热管的流量分配的均匀性，以达到提高热管理部件的换热均匀性的效果。
并且，第一进出液口和第二进出液口均设置于第一端，方便热管理部件的维护，且将热管理部件装配筋电池箱体内后，只需要在箱体的一侧预留一个避让口即可实现进出液管的安装和收纳，避免热管理部件占用电池箱体内过多空间，有利于提高电池的空间利用率。

电池单体包括电极组件和电解液，电极组件由正极极片、负极极片和隔离膜组成。电池单体主要依靠金属离子在正极极片和负极极片之间移动来工作。正极极片包括正极集流体和正极活性物质层，正极活性物质层涂覆于正极集流体的表面，未涂敷正极活性物质层的正极集流体凸出于已涂覆正极活性物质层的正极集流体，未涂敷正极活性物质层的正极集流体作为正极极耳。以锂离子电池为例，正极集流体的材料可以为铝，正极活性物质可以为钴酸锂、磷酸铁锂、三元锂或锰酸锂等。负极极片包括负极集流体和负极活性物质层，负极活性物质层涂覆于负极集流体的表面，未涂敷负极活性物质层的负极集流体凸出于已涂覆负极活性物质层的负极集流体，未涂敷负极活性物质层的负极集流体作为负极极耳。负极集流体的材料可以为铜，负极活性物质可以为碳或硅等。为了保证通过大电流而不发生熔断，正极极耳的数量为多个且层叠在一起，负极极耳的数量为多个且层叠在一起。隔离膜的材质可以为PP(polypropylene，聚丙烯)或PE(polyethylene，聚乙烯)等。此外，电极组件可以是卷绕式结构，也可以是叠片式结构，本申请实施例并不限于此。
温度对于电池的性能有重要的影响，所以常规技术中的电池会设置热管理部件，用于对电池降温或在低温环境下对电池加热升温，使电池达到正常工作温度区间。然而，现有技术的热管理部件存在换热性能不均的问题，从而影响电池温度的均 匀性。
现有的应用成熟的一种热管理部件包括进液集流体、出液集流体以及并排设置在进液集流体和出液集流体之间的并联连通的多个换热管，申请人研究发现，在实际使用中，流体进入集流体后分路向多个换热管流动，而沿集流体的长度方向，越远离进液口的换热管，其流量越小，从而导致热管理部件的沿集流体延伸方向上排布的各换热管内流量分配不均匀，从而导致热管理部件换热性能不均的问题，造成电池内温差大的问题。
基于以上考虑，为了解决热管理部件换热性能不均的问题，申请人经过研究，设计了一种热管理部件，在第一集流管设置并列的第一流道和第二流道，且第一流道和第二流道均从所述第一集流管的第一端延伸至所述第一集流管的第二端，同时，第一进出液口设置于第一端与第一流道连通，第二流道与换热管连通，也就是说，第一集流管上的第一进出液口布置在远离换热管的一侧第一流道。第二进出液口与第一进出液口位于同一侧，第一进出液口和第二进出液口一个用于进液，一个用于出液。即，第一集流管可以用于进液集流管也可以用于出液集流管。
在本申请中，当第一集流管用于进液集流管时，流体经第一进出液口进入第一流道并沿第一流道向第二端流动，进入第二通道后再沿第二通道流动然后进入到每个换热管中，最终经第二集流管的第二进出液口排出；同样的，当第一集流管用于出液集流管时，则各换热管内的流体进入到第二流道后沿第一集流管的长度方向向第二端的流通，再从第二流道与第一流道的连通处折回，在第一流道内向第一端流通并经第一进出液口排出。
本申请的热管理部件通过在第一集流管内设置第一流道和第二流道，使得流体能够在进液集流体中或出液集流体中向远离第一进出液口和第二进出液口的一端分配，从而缓解靠近第一端的换热管流量大、靠近第二端的换热管流量小的问题，通过均衡流体流经每个换热管的路径长度的手段降低各换热管之间的流量差，提高并联设置的换热管的流量分配的均匀性，以达到提高热管理部件的换热均匀性的效果。
本申请实施例公开的热管理部件可以用于电池单体的冷却或加热，本申请实施例公开的具有热管理部件的电池可以但不限用于车辆、船舶或飞行器等用电设备中，可以使用具备本申请公开的热管理部件的电池组成该用电设备的电源系统，这样，热管理部件可以为电池降温，也可以为在低温环境下工作的电池加热升温，使电池单体达到工作区间温度，以正常供电。

请参照图3，并进一步参照图4，图3为本申请一些实施例提供的热管理部件的轴测图，图4为本申请一些实施例提供的热管理部件的俯视图。本申请一些实施例提供的热管理部件30包括第一集流管31、第二集流管32和多个换热管33，第一集流管31包括依次连通的第一进出液口316、第一流道313和第二流道314，第一流道313和第二流道314均从第一集流管31的第一端延伸至第一集流管31的第二端，第一进出液口316设置于第一端，第一流道313的一端与第一进出液口316连通，另一端与第二流道314连通。第二集流管32与第一集流管31相互平行且间隔设置，包括相互连通的第二进出液口322和第三流道321，第二进出液口322设置于第二集流管32的 靠近第一进出液口316的一端。多个换热管33并排设置于第一集流管31和第二集流管32之间，每个换热管33的一端与第二流道314连通，另一端与第三流道321连通。
可以理解的是，第一集流管31的第一端是指第一集流管31的沿自身长度方向的一端，第一集流管31的第二端是指第一集流管31的沿自身长度方向的另一端，第一集流管31用于通入流体，第一集流管31的第一端的端口和第二端的端口可以封闭。
具体而言，请参照图3，第一集流管31和第二集流管32沿第一方向X间隔设置，第一集流管31和第二集流管32的长度方向沿第二方向Y延伸，多个换热管33沿第二方向Y间隔设置。
“第一集流管31包括依次连通的第一进出液口316、第一流道313和第二流道314，第一流道313和第二流道314均从第一集流管31的第一端延伸至第一集流管31的第二端”，是指第一流道313和第二流道314均从第一集流管31的第一端向第一集流管31的第二端延伸，并最终在靠近第二端处相互连通。
第一集流管31和第二集流管32可以为常规形状的管体311结构，比如圆形管、矩形管、椭圆形管等。同样的，换热管33也可以为常规形状的管体311结构，比如圆形管、矩形管、椭圆形管、口琴管等。
换热管33的材质可以采用导热性能优良的金属材质，比如铝、铜等，示例性的，换热管33可以为铝管。
换热管33和第一集流管31以及第二集流管32可以通过焊接、螺接等连接方式固定连接。
第一集流管31、第二集流管32和多个换热管33连通形成热管理器，热管理器内通入流体，通过控制流体的温度使得热管理部件30具有热交换功能。流体可以为冷却液，通过控制冷却液的热量以调整热管理器的热交换功能，以使热管理器具备冷却功能或加热功能。
其中，第一集流管31和第二集流管32中的一者用于向多个并排设置的换热管33内通入流体，第一集流管31和第二集流管32中的另一者用于收集从多个并排设置的换热管33内流出的流体，也就是说，第一进出液口316可以作为进液口也可以作为出液口，同样的，第二进出液口322可以作为进液口也可以作为出液口。当然，当第一进出液口316作为进液口时，第二进出液口322作为出液口。而当第一进出液口316作为出液口时，第二进出液口322作为进液口。当然，热管理部件30还可以包括进液接头和出液接头，进液管接头34安装在进液口，出液管接头35安装在出液口。
在一些实施例中，请参照图4，第一进出液口316安装进液管接头34，第二进出液口322安装出液管接头35，流体经第一进出液口316进入第一流道313，沿第一集流管31的长度方向(即Y方向)向第二端流通，在靠近第二端处进入第二流道314，并在第二流道314内流通并进入多个换热管33，分流至多个换热管33的流体汇入第二集流管32的第三流道321，并最终经第二进出液口322排出，使得流体在热管理部件30内流经每个换热管33的路径长度更加均衡。
在又一些实施例中，请参照图5，图5为本申请又一些实施例提供的热管理部件的俯视图，第一进出液口316安装出液管接头35，第二进出液口322安装进液管接头34，流体经第二进出液口322进入第三流道321，在第三流道321内流通并进入多个换热管33，分流至多个换热管33的流体汇入第一集流管31的第二流道314，沿第一集流管31的长度方向(即Y方向)向第二端流通，并在靠近第二端处进入第一流道313，最终经第一进出液口316排出，使得流体在热管理部件30内流经每个换热管33的路径长度更加均衡。
热管理部件30通过在第一集流管31内设置第一流道313和第二流道314，使得流体能够在进液集流体中或出液集流体中向远离第一进出液口316和第二进出液口322的一端分配，从而缓解靠近第一端的换热管33流量大、靠近第二端的换热管33流量小的问题，通过采用均衡流体流经每个换热管33的路径长度的手段降低各换热管33之间的流量差，提高并联设置的换热管33的流量分配的均匀性，以达到提高热管理部件30的换热均匀性的效果。
在一些实施例中，请参照图5并进一步参照图6，图6为本申请一些实施例提供的热管理部件的主视图。第一集流管31包括管体311和分隔件312,分隔件312设置在管体311内且沿管体311的长度方向延伸，分隔件312将管体311的内部空间分隔成第一流道313和第二流道314。
可以理解的是，管体311的两端分别对应第一集流管31的第一端和第二端，分隔件312设置在管体311内前沿管体311的长度方向自管体311的与第一端对应的一端向与第二端对应的一端延伸。
分隔件312的实施方式可以采用多种结构，比如板状、管状，板状的分隔件312可以为平面状、曲面状等。
分隔件312和管体311可以一体成型，也可以通过焊接等方式固定连接，可以理解的是，为了保证第一流道313和第二流道314的相互独立性，分隔件312与管体311的内周壁的连接处可以为密封连接。
第一集流管31包括管体311和分隔件312，由分隔件312将管体311的内部空间分隔成第一流道313和第二流道314，其结构简单易于加工，且加工成本低，实用性强。
在一些实施例中，如图5所示，在管体311的长度方向上，分隔件312靠近第二端的一端与管体311之间具有间隙315，间隙315用于连通第一流道313和第二流道314。
其中，分隔件312沿管体311的长度方向自管体311的与第一端对应的一端向管体311的与第二端对应的一端延伸，以在管体311的内腔分隔出沿管体311的长度方向延伸的并列的第一流道313和第二流道314，分隔件312靠近第二端的一端与管体311的与第二端对应的一端之间具间隙315，使得第一流道313和第二流道314通过间隙315连通。
通过设定分隔件312长度即可控制间隙315的大小，也就是控制第一流道313和第二流道314连通处流量的大小，实施结构简单易加工成型。
在其他一些实施例中，在管体311的长度方向上，分隔件312可以自管体311的与第一端对应的一端一直延伸至管体311的与第二端对应的一端，以将管体311分隔成并列的互不连通的第一流道313和第二流道314，然后在在分隔件312上靠近第二端的一端设置一个或多个开口，通过开口连通第一流道313和第二流道314。
在一些实施例中，请参照图6并进一步参照图7，图7为图6所示的第一集流管的主视图。管体311呈矩形管状，并且包括沿管体311的厚度方向彼此相对的顶壁3111和底壁3112以及沿管体311的宽度方向彼此相对的第一侧壁3113和第二侧壁3114，分隔件312连接在顶壁3111和底壁3112之间。
具体而言，请参照图6，图6为本申请一些实施例提供的固定带的轴测图；管体311的宽度方向沿第一方向X延伸，管体311的厚度方向沿第三方向Z延伸。
管体311呈矩形管状，一方面矩形管可在其管壁形成足够的安装面积，便于换热管33的安装，另一方面矩形管可有效增加管体311的外壁与周围部件的接触面积，这样，在将热管理部件30组装至电池100箱体20时方便限位，且避免管体311占用过多电池100箱体20的内部空间，结构稳定性和成组适配性好。
在一些实施例中，如图7所示，分隔件312包括主体部3121、第一连接部3122和第二连接部3124，第一连接部3122和第二连接部3124分别从主体部3121的两侧朝相反的方向延伸，第一连接部3122连接于顶壁3111，第二连接部3124连接于底壁3112。
其中，第一连接部3122和第二连接部3124可以和主体一体成型，也可以和主体分体设置并通过焊接、胶粘等方式连接为整体。
第一连接部3122可以和顶壁3111平行或和顶壁3111呈一定夹角，同样的，第二连接部3124也可以和底壁3112相互平行或呈一定夹角。示例性的，第一连接部3122与顶壁3111平行，第一连接部3122包括朝向顶壁3111的第一表面3123，第一表面3123与顶壁3111贴合，第二连接部3124包括朝向底壁3112的第二表面3125，第二表面3125与底壁3112贴合。
分隔件312通过第一连接部3122和第二连接部3124与管体311的顶壁3111和底壁3112连接，并且第一连接部3122与顶壁3111面接触以及第二连接部3124与底壁3112面接触，有利于保证连接的稳固性，同时，分隔件312倾斜设置，可有效避免将管体311的顶壁3111、底壁3112、第一侧壁3113或第二侧壁3114分属第一流道313或第二流道314，避免减小管体311的进出液管和换热管33的安装面积。
在一些实施例中，请参照图7，第一进出液口316设置于顶壁3111，方便进出液管的拆装维护。
在又一些实施例中，请再次参照图5并进一步参照图8，图8为本申请又一些实施例提供的热管理部件的主视图。分隔件312可以呈管状，分隔件312的内腔形成第一流道313，分隔件312的外周壁与管体311的内周壁之间形成第二流道314。
也就是说，在管体311内穿设固定一个管状结构，即可在管体311内分隔出第一流道313和第二流道314，一方面，加工难度低便于实施，另一方面管状的分隔件312本身结构强度高，有利于进一步提高整体第一集流管31的结构稳定性，从而保证 第一集流管31的功能稳定性。
在一些实施例中，换热管33为口琴管。
口琴管是热交换系统中常用的流体承载件，其技术成熟，实用性强。
常规的口琴管呈扁管状，包括主体和间隔设置在主体的内腔的多个分隔壁，多个分隔壁将主体的内腔分成多个子内腔，多个子内腔用于供流体流通。
可以理解的是，在本实施例的热管理部件30中，多个口琴管沿第二方向Y间隔设置，其中，口琴管的面积较大的表面可以垂直于第二方向Y设置，使得相邻两个口琴管之间形成一个电池100容纳腔。当然，如图2所示，口琴管的面积较大的表面也可以平行于第二方向Y设置，使得多个口琴管共同形成一个热管理表面，热管理表面可以与电池100接触。
换热管33使用口琴管，口琴管的结构有利于进一步提高换热管33在其宽度方向上的热均衡性，且口琴管结构具有较大的外表面，便于提高换热管33与电池100的接触面积，从而提高换热管33对电池100的热交换效果。
请参照图3至图8，本申请一些实施例提供的热管理部件30包括第一集流管31、第二集流管32和多个换热管33，第一集流管31包括依次连通的第一进出液口316、第一流道313和第二流道314，第一流道313和第二流道314均从第一集流管31的第一端延伸至第一集流管31的第二端，第一进出液口316设置于第一端，第一流道313的一端与第一进出液口316连通，另一端与第二流道314连通。第二集流管32与第一集流管31相互平行且间隔设置，包括相互连通的第二进出液口322和第三流道321，第二进出液口322设置于第二集流管32的靠近第一进出液口316的一端。多个换热管33并排设置于第一集流管31和第二集流管32之间，每个换热管33的一端与第二流道314连通，另一端与第三流道321连通。
第一集流管31包括管体311和分隔件312,管体311呈矩形管状，并且包括沿管体311的厚度方向彼此相对的顶壁3111和底壁3112以及沿管体311的宽度方向彼此相对的第一侧壁3113和第二侧壁3114，分隔件312连接在顶壁3111和底壁3112之间且沿管体311的长度方向延伸，分隔件312将管体311的内部空间分隔成第一流道313和第二流道314。在管体311的长度方向上，分隔件312靠近第二端的一端与管体311之间具有间隙315，间隙315用于连通第一流道313和第二流道314。
分隔件312包括主体部3121、第一连接部3122和第二连接部3124，第一连接部3122和第二连接部3124分别从主体部3121的两侧朝相反的方向延伸，第一连接部3122连接于顶壁3111，第二连接部3124连接于底壁3112。
第二方面，本申请提供了一种电池100，包括：箱体20、电池单体10和以上任一方案所述的热管理部件30，热管理部件30设置于箱体20内，热管理部件30用于容纳流体以调节电池单体10的温度。
