电动汽车在不同行驶状况下运行时，电池会产生大量热量，电池温度过高会导致电池寿命和性能降低，所以需要对电池进行冷却。目前通常采用冷却板对电池进行冷却，为了确保冷却效果，每一个电芯的底部和侧部均需要设置单独的冷却板，并且，冷却板还需要专门的固定支架进行安装固定。如此，每一个电芯对应的冷却板的数量和固定支架的数量过多，导致电池包整体的重量和体积均大幅增加，从而降低了电池包的能量密度并增大了电池包的安装空间。
请参阅图1-图12，为了解决每一个电芯对应的冷却板的数量和固定支架的数量过多，导致电池包整体的重量和体积均大幅增加，从而降低了电池包的能量密度并增大了电池包的安装空间的问题，本申请提供一种电池换热集成结构10。该电池换热集成结构10包括中间换热板300、第一换热板100和第二换热板200。第一换热板100一端连接中间换热板300，另一端朝向远离中间换热板300的方向延伸，多个第一换热板100间隔设置于中间换热板300的一侧，相邻第一换热板100和中间换热板300围设形成第一固定槽110，第一固定槽110用于固定一个或多个第一电池模块，且第一电池模块的底部贴设于中间换热板300，第一电池模块相对的两侧分别贴设于相邻的第一换热板100。第二换热板200一端连接中间换热板300，另一端朝向远离中间换热板300的方向延伸，多个第二换热板200间隔设置于中间换热板300背离第一换热板100的一侧，且相邻第二换热板200和中间换热板300围设形成第二固定槽210，第二固定槽210用于固定一个或多个第二电池模块，且第二电池模块的底部贴设于中间换热板300，第二电池模块相对的两侧分别贴设于相邻的第二换热板200。
需要说明的是，第一电池模块或者第二电池模块包括但不限于电池模组和电芯。并且，第一电池模块固定于第一固定槽110的方式包括但不限于通过相邻第一换热板100的夹持作用卡住第一电池模块，同样地，第二电池模块固定于第二固定槽210的方式包括但不限于通过相邻第二换热板200的夹持作用卡住第二电池模块。
进一步地，需要说明的是，中间换热板300、第一换热板100和第二换热板200均为导热率较高的材质，例如铝合金、铁合金或者铜合金。
由于相邻的第一电池模块共用一块第一换热板100，且相邻的第二电池模块共用一块第二换热板200，进一步地，第一电池模块和第二电池模块共用一块中间换热板300。因此，如此设置，大大减少了第一电池模块和第二电池模块所需的总的换热板(包括设于侧边的换热板和设于底部的换热板)的数量，从而在保证电池模块(包括第一电池模块和第二电池模块)的换热效率的基础上，减小了整个电池包的重量和体积，进而提高了电池包的能量密度并减小了电池包的安装空间。
更进一步地，由于第一固定槽110能够固定一个或多个第一电池模块，且第二固定槽210能够固定一个或多个第二电池模块。因此，第一换热板100、第二换热板200和中间换热板300围设形成的结构还能够用于安装固定第一电池模块和第二电池模块，也即，本申请提供的电池换热集成结构10无需另外设置安装支架用于安装第一电池模块和第二电池模块。
综上可知，本申请提供的电池换热集成结构10，有效解决了每一个电芯对应的冷却板的数量和固定支架的数量过多，导致电池包整体的重量和体积均大幅增加，从而降低了电池包的能量密度并增大了电池包的安装空间的问题。
在一实施例中，如图1和图2所示，第一换热板100和第二换热板200均呈波浪形弯曲设置。
如此，有利于第一换热板100和第二换热板200夹持圆柱形的电芯。
但不限于此，在其他实施例中，第一换热板100和第二换热板200还可以均呈阶梯型弯折设置。
如此，有利于第一换热板100和第二换热板200夹持方块形的电芯。
在其他实施例中，如图5所示，第一换热板100和第二换热板200还可以均呈平面型设置。
在一实施例中，第一换热板100和第二换热板200分别焊接于中间换热板300的两侧。
如此，有效提高了电池换热集成结构10的连接强度，且降低了电池换热集成结构10的装配难度。
但不限于此，在其他实施例中，第一换热板100和第二换热板200还可与中间换热板300卡接。或者，第一换热板100和第二换热板200还可与中间换热板300通过紧固件可拆卸连接，在此不一一列举。
在一实施例中，如图4所示，第一换热板100设有第一换热通道120，第二换热板200设有第二换热通道220，中间换热板300设有中间换热通道310，第一换热通道120的进液端和第二换热通道220的进液端分别连通中间换热通道310的进液端，且第一换热通道120的出液端和第二换热通道220的出液端分别连通中间换热通道310的出液端。
如此，换热介质(包括但不限于冷却液)能够从中间换热通道310的进液端进入中间换热通道310，再从中间换热通道310的出液端离开中间换热通道310。并且，换热介质还能从中间换热通道310的进液端进入第一换热通道120和第二换热通道220。也即，如此设置，实现了第一换热通道120、第二换热通道220和中间换热通道310的相互连通，大大降低了电池换热集成结构10内换热介质的循环难度。
进一步地，在一实施例中，如图4所示，第一换热板100设于中间换热板300的上方，第二换热板200设于中间换热板300的下方。第一换热板100设有扩口部130，中间换热通道310通过扩口部130连通第一换热通道120，且扩口部130的横截面从连通第一换热通道120的一端至连通中间换热通道310的一端呈扩张状，第二换热板200设有缩口部230，中间换热通道310通过缩口部230连通第二换热通道220，且缩口部230的横截面从连通第二换热通道220的一端至连通中间换热通道310的一端呈收缩状，并且，扩口部130的最大横截面积大于缩口部230的最小横截面积。
由于扩口部130的横截面从连通第一换热通道120的一端至连通中间换热通道310的一端呈扩张状，因此，扩口部130靠近中间换热通道310处的横截面积最大。同样地，由于缩口部230的横截面从连通第二换热通道220的一端至连通中间换热通道310的一端呈收缩状，因此，缩口部230靠近中间换热通道310处的横截面积最小。通过设置扩口部130的最大横截面积大于缩口部230的最小横截面积，有利于增大通过扩口部130进入第一换热通道120的换热介质的流量，并且，也减小了通过缩口部230进入第二换热通道220的
换热介质的流量。又因为第一换热板100设于中间换热板300的上方，第二换热板200设于中间换热板300的下方。因此，通过设置缩口部230和扩口部130，能够有效平衡由于重力导致的进入第一换热通道120的换热介质的量明显少于进入第二换热通道220的换热介质的量的问题。
进一步地，由于扩口部130的横截面从连通第一换热通道120的一端至连通中间换热通道310的一端呈扩张状，因此，中间换热板300内的换热介质从扩口部130进入第一换热通道120时，由于流通面积的缩小，换热介质的流通速度会显著增大，如此，有利于换热介质克服重力作用上升至第一换热通道120内的更高处。
更进一步地，在一实施例中，如图4所示，扩口部130的最大内径a、扩口部130的最小内径b、缩口部230的最大内径c和缩口部230的最小内径d，满足以下关系式：d<b<c<a。
如此设置，能够进一步有效平衡第一换热通道120和第二换热通道220内不同高度处的换热介质的流通量。
在一实施例中，如图2和图3所示，中间换热板300包括第一盖板320、第二盖板330和中心主板340，中心主板340设有沿着厚度方向贯穿自身的连通槽341，第一盖板320和第二盖板330沿着中心主板340的厚度方向分别盖设于中心主板340的两侧并与连通槽341围设形成中间换热通道310。
如此设置，有利于换热介质通过中间换热通道310的进液端快速分配至第一换热通道120、第二换热通道220和中间换热通道310。并且，由于连通槽341沿着厚度方向贯穿中心主板340，因此，在中心主板340上加工出连通槽341的难度大大降低，也即，降低了电池换热集成结构10的加工难度。
具体地，第一盖板320和第二盖板330上分别设有多个连通孔，第一换热通道120和第二换热通道220分别通过不同的连通孔连通中间换热通道310。
但不限于此，在其他实施例中，中间换热板300还可以是双层板结构，也即，可以是直接通过两层盖板围设形成中间换热通道310。
进一步地，在一实施例中，中心主板340通过冲压加工形成连通槽341，或者，中心主板340通过浇铸成型形成连通槽341。
进一步地，在一实施例中，第一盖板320、第二盖板330和中心主板340之间通过紧固件可拆卸连接，或者，第一盖板320和第二盖板330分别焊接于中心主板340的两侧。
在一实施例中，如图3所示，连通槽341包括进液集流槽342和出液集流槽343，且连通槽341还包括多个并列设置的分液槽344，多个分液槽344分别连通进液集流槽342和出液集流槽343。
如此设置，有利于提高中间换热通道310不同位置处的换热均匀性。
更进一步地，在一实施例中，分液槽344呈S型。
如此设置，有利于增大连通槽341的总路径长度，也即，有利于增大换热介质在中间换热通道310内的流通路径的长度，进而提高电池换热集成结构10的换热均匀性。
但不限于此，分液槽344还可以呈一字型或者比S型弯曲次数更多的蛇形。
在一实施例中，如图1和图2所示，电池换热集成结构10还包括进液总管400和出液总管500，进液总管400连通于中间换热板300的进液端，出液总管500连通于中间换
热板300的出液端。
如此，有利于电池换热集成结构10内换热介质的分散和集中。
具体地，进液总管400和出液总管500分别连接于第一盖板320的两端。
通常，第一电池模块和第二电池模块均为竖直设置，因此，设置于第一电池模块侧部的第一换热板100对应第一电池模块竖直设置，并且，设置于第二电池模块侧部的第二换热板200对应第二电池模块竖直设置。
但是，第一换热板100和第二换热板200竖直设置，会导致第一换热板100和第二换热板200内的换热介质分布不均，也即，第一换热板100和第二换热板200内的换热介质容易在重力作用下集中分布于第一换热板100和第二换热板200的下端，如此，不利于第一换热板100和第二换热板200内换热介质在竖直方向上的均匀分布。
请参阅图6-图12，为了解决第一换热板100和第二换热板200内的换热介质在竖直方向上无法均匀分布的问题。在一实施例中，第一换热板100设有进液集流通道141、出液集流通道151和分液通道161，进液集流通道141和出液集流通道151均为竖直设置，多个分液通道161沿着水平方向平行分布，且多个分液通道161分别连通进液集流通道141和出液集流通道151。将多个分液通道161从上至下按顺序划分成奇数位通道162和偶数位通道163，进液集流通道141内设有多个第一阻隔板142，且第一阻隔板142均设于上方的奇数位通道162和下方的偶数位通道163之间，以使上方的奇数位通道162和下方的偶数位通道163在进液集流通道141内不连通。出液集流通道151内设有多个第二阻隔板152，且第二阻隔板152均设于上方的偶数位通道163和下方的奇数位通道162之间，以使上方的偶数位通道163和下方的奇数位通道162在出液集流通道151内不连通。第二换热板200和第一换热板100在竖直方向上呈镜像对称设置。
需要说明的是，奇数位通道162指的是从上往下数，第1、3、5和7等奇数顺序的分液通道161，偶数位通道163指的是从上往下数，第2、4、6和8等偶数顺序的分液通道161。
由于上方的奇数位通道162和下方的偶数位通道163在进液集流通道141内不连通，且上方的偶数位通道163和下方的奇数位通道162在出液集流通道151内不连通。因此，可知，换热介质能够在第一换热板100内形成蛇形的迂回通道，并且，换热介质在分液通道161内迂回的次数越多，则分液通道161被划分得越细，换热介质在第一换热板100内的分布越均匀。因此可知，如此设置，可避免换热介质全部集中在第一换热板100的底部，大大提高了换热介质在第一换热板100内沿着竖直方向的分布均匀性。
进一步地，需要说明的是，针对“第二换热板200和第一换热板100在竖直方向上呈镜像对称设置”，其与第一换热板100和第二换热板200在水平面上的分布情况无关，也即，第一换热板100和第二换热板200在水平面上可以是错位分布的，也可以是平行分布的，还可以是交叉分布的。
又因为第二换热板200和第一换热板100在竖直方向上呈镜像对称设置，因此，换热介质在第二换热板200内也呈蛇形迂回流动，同样增大了第二换热板200内换热介质的分布均匀性。并且，第二换热板200和第一换热板100在竖直方向上呈镜像对称设置，可使第二换热板200和第一换热板100共用一个进液口和出液口，大大降低了电池换热集成结构10的结构复杂程度。
但不限于此，第二换热板200和第一换热板100在竖直方向也可以是重复排列设置。
在一实施例中，如图6所示，奇数位通道162的数量大于偶数位通道163的数量。
如此，可使第一换热板100内换热介质最终从出液集流通道151流出。
进一步地，在一实施例中，如图6-图10所示，进液集流通道141的底端和中间换热板300隔断，且进液集流通道141内设有直通管143，直通管143一端连通中间换热板300，另一端依次穿过多个第一阻隔板142并延伸至进液集流通道141的最上端，以使中间换热板300能够通过直通管143直接连通最上方的分液通道161。
如此，可使中间换热板300内的换热介质直接进入最上方的分液通道161，并使换热介质从最上方分液通道161迂回流动至最下方的分液通道161。
但不限于此，在其他实施例中，如图13所示，进液集流通道141还可以分隔成竖直并列设置的第一通道147和第二通道148，第一通道147直接连通中间换热板300和进液集流通道141的最上端，第一阻隔板142设于第二通道148内。
更进一步地，在一实施例中，直通管143的内径从靠近中间换热板300的方向至远离中间换热板300的方向逐渐减小。
如此设置，有利于提高直通管143内换热介质的流速，进而有利于换热介质进入最上方的分液通道161内。
在一实施例中，如图8-图10所示，分液通道161包括多个沿着水平方向平行分布的分支通道164，多个分支通道164分别连通进液集流通道141和出液集流通道151。
如此，对每一个分液通道161在竖直方向上进行再次分隔，提高了换热介质在每一个分液通道161竖直方向上的分布均匀性，也即，进一步提高了换热介质在整个第一换热板100内的分布均匀性。
在一实施例中，如图6-图10所示，第一换热板100包括进液集流管140、出液集流管150和分液管160，进液集流管140设有进液集流通道141，出液集流管150设有出液集流通道151，分液管160设有分液通道161。
如此，降低了第一换热板100的装配难度。
进一步地，在一实施例中，如图11所示，进液集流管140的侧部设有多个第一安装槽144，第一安装槽144沿着进液集流管140的截面方向贯穿进液集流管140的一侧侧壁并形成第一装配口145，且第一阻隔板142通过第一装配口145安装于第一安装槽144。
如此，大大降低了第一阻隔板142的安装难度。
同样地，在一实施例中，如图12所示，出液集流管150的侧部设有多个第二安装槽153，第二安装槽153沿着出液集流管150的截面方向贯穿出液集流管150的一侧侧壁并形成第二装配口154，且第二阻隔板152通过第二装配口154安装于第二安装槽153。
如此，大大降低了第二阻隔板152的安装难度。
进一步地，在一实施例中，如图11所示，进液集流管140设有沿着竖直方向延伸的进液连槽146，多个分液通道161分别通过进液连槽146连通进液集流通道141。
同样地，在一实施例中，如图12所示，出液集流管150设有沿着竖直方向延伸的出液连槽155，多个分液通道161分别通过出液连槽155连通出液集流通道151。
如图14所示，本申请还提供一种热管理系统20，该热管理系统20包括以上任意一个实施例所述的电池换热集成结构10。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本申请的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对申请专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干变形和改进，这些都属于本申请的保护范围。因此，本申请的专利保护范围应以所附权利要求为准。
