第二分隔件131、第一分隔件111分别与隔板120相对的两侧连接。The second partition member 131 and the first partition member 111 are respectively connected to opposite sides of the partition plate 120 .
相邻两个第二分隔件131之间围设而成第二腔体132。相邻两个第二分隔件131、隔板120与外边板130共同围设而成第二腔体132，第二腔体132用于容纳隔热材料。A second cavity 132 is formed between two adjacent second partitions 131 . A second cavity 132 is formed by two adjacent second partitions 131 , the partition 120 and the outer plate 130 , and the second cavity 132 is used for accommodating the heat insulating material.
相应地，隔板120、外边板130与多个第二分隔件131围设而成多个第二腔体132，多个第二腔体132可以相互连通，也可以不相互连通；或者，部分第二腔体132相互连通，部分第二腔体132不相互连通。Correspondingly, the partition plate 120 , the outer side plate 130 and the plurality of second partitions 131 are surrounded to form a plurality of second cavities 132 , and the plurality of second cavities 132 may or may not communicate with each other; The second cavities 132 are communicated with each other, and some of the second cavities 132 are not communicated with each other.
在本申请的实施例中，多个第二分隔件131呈阵列的方式布置于隔板120的一侧且与隔板120连接。In the embodiment of the present application, the plurality of second partitions 131 are arranged on one side of the partition plate 120 in an array manner and are connected to the partition plate 120 .
相应地，第二分隔件131除了具有围设成第二腔体132的作用外，第二分隔件131还兼顾有增加隔板120的强度的作用，第二分隔件131呈阵列的方式布置，有利于均分分布于隔板120的载荷，避免隔板120因为应力不均衡而弯曲或者变形。Correspondingly, in addition to the function of enclosing the second cavity 132, the second partition 131 also has the function of increasing the strength of the partition 120. The second partitions 131 are arranged in an array. It is beneficial to evenly distribute the load on the separator 120 and prevent the separator 120 from being bent or deformed due to unbalanced stress.
需要说明的是，在本申请的其他实施例中，第二分隔件131也可以不采用阵列的方式布置于隔板120，例如任意相邻两个第二分隔件131之间的距离可以不完全相同。It should be noted that, in other embodiments of the present application, the second partitions 131 may not be arranged on the partition 120 in an array manner, for example, the distance between any two adjacent second partitions 131 may not be completely same.
在本申请中，沿电池箱底板100的厚度方向，第一分隔件111的投影与第二分隔件131的投影不重合。换言之，第一分隔件111沿电池箱底板100的厚度方向具有投影，第二分隔件131沿电池箱底板100的厚度方向也具有投影，上述两个投影并不重合、相互独立。In the present application, along the thickness direction of the battery box bottom plate 100 , the projection of the first partition member 111 does not coincide with the projection of the second partition member 131 . In other words, the first partition member 111 has a projection along the thickness direction of the battery box bottom plate 100 , and the second partition member 131 also has a projection along the thickness direction of the battery box bottom plate 100 .
在隔板120相对的两侧，第一分隔件111对应设置于第二分隔件131之间的空隙处。On opposite sides of the partition plate 120 , the first partitions 111 are correspondingly disposed in the gaps between the second partitions 131 .
承上所述，相邻两个第一分隔件111围设成第一腔体112，相邻两个第二分隔件131围设成第二腔体132。在第二腔体132的作用下，第一腔体112内的冷却液的冷量不易传递至 外边板130。Based on the above, two adjacent first partitions 111 enclose a first cavity 112 , and two adjacent second partitions 131 enclose a second cavity 132 . Under the action of the second cavity 132, the cold energy of the cooling liquid in the first cavity 112 is not easily transferred to the outer side plate 130.
作为示例性地，第一腔体112可供冷却液例如冷却水流过，第二腔体132可填充隔热材料。可以理解的是，第二腔体132可被设置为供冷却液例如冷却水流过，第一腔体112填充隔热材料。在本实施例中，以第一腔体112可供冷却液例如冷却水流过，第二腔体132填充隔热材料作为示例进行描述。As an example, the first cavity 112 may flow a cooling liquid, such as cooling water, and the second cavity 132 may be filled with a thermal insulating material. It can be understood that, the second cavity 132 may be configured for cooling liquid such as cooling water to flow therethrough, and the first cavity 112 is filled with insulating material. In this embodiment, the first cavity 112 can be used for cooling liquid, such as cooling water, to flow through, and the second cavity 132 is filled with heat insulating material as an example for description.
第一腔体112内的冷却液的冷量先传递至隔板120，然后经过第二腔体132内的隔热材料然后再传递至外边板130，第二腔体132内的隔热材料具有较佳的隔热效果。此外，第一腔体112内的冷却液的冷量先传递至隔板120，然后经过与隔板120连接的第二分隔件131传递至外边板130。沿电池箱底板100的厚度方向，第一分隔件111的投影与第二分隔件131的投影不重合；延长第一腔体112内的冷量经过隔板120、第二分隔件131至外边板130的路径长度，以降低传热效率，提高冷却液对电池模组的冷却效果。The cold energy of the cooling liquid in the first cavity 112 is first transferred to the partition plate 120, then passes through the heat insulating material in the second cavity 132, and then is transferred to the outer side plate 130. The heat insulating material in the second cavity 132 has Better thermal insulation. In addition, the cold energy of the cooling liquid in the first cavity 112 is first transferred to the partition plate 120 , and then transferred to the outer side plate 130 through the second partition member 131 connected to the partition plate 120 . Along the thickness direction of the bottom plate 100 of the battery box, the projection of the first partition 111 and the projection of the second partition 131 do not overlap; the cooling capacity in the extended first cavity 112 passes through the partition 120 and the second partition 131 to the outer plate The path length of 130 can reduce the heat transfer efficiency and improve the cooling effect of the coolant on the battery module.
此外，第一分隔件111、第二分隔件131间隔布置，有利于增加电池箱底板100的强度。In addition, the first partition member 111 and the second partition member 131 are arranged at intervals, which is beneficial to increase the strength of the battery box bottom plate 100 .
在本申请的实施例中，第一分隔件111与第二分隔件131可以具有多种布置方式，例如图2中所示的方式，沿电池箱底板100的厚度方向，相邻两个第一分隔件111之间设置有一个第二分隔件131。换言之，沿电池箱底板100的厚度方向，一个第一分隔件111的投影位于相邻两个第二分隔件131的投影之间。In the embodiment of the present application, the first separator 111 and the second separator 131 may have various arrangements. For example, as shown in FIG. 2 , along the thickness direction of the battery box bottom plate 100 , two adjacent first separators A second partition 131 is disposed between the partitions 111 . In other words, along the thickness direction of the battery box bottom plate 100 , the projection of one first partition 111 is located between the projections of two adjacent second partitions 131 .
采用相互交错的布置方式，有利于均衡隔板120相对两侧的载荷。The staggered arrangement is beneficial to equalize the loads on opposite sides of the baffle 120 .
需要说明的是，在本申请的其他实施例中，第一分隔件111和第二分隔件131的相对位置关系可以为其他。It should be noted that, in other embodiments of the present application, the relative positional relationship between the first partition member 111 and the second partition member 131 may be other.
例如，图4示出了本申请实施例提供的第一分隔件111和第二分隔件131另一种布置方式。For example, FIG. 4 shows another arrangement of the first spacer 111 and the second spacer 131 provided by the embodiment of the present application.
请参阅图4，在图4所示的实施方式中，内边板110、隔板120以及外边板130均为板状，内边板110、隔板120以及外边板130通过焊接的方式连接。沿电池箱底板100的厚度方向，相邻两个第二分隔件131的投影之间具有两个第一分隔件111的投影。Referring to FIG. 4 , in the embodiment shown in FIG. 4 , the inner side plate 110 , the partition plate 120 and the outer side plate 130 are all plate-shaped, and the inner side plate 110 , the partition plate 120 and the outer side plate 130 are connected by welding. Along the thickness direction of the battery box bottom plate 100 , there are projections of two first partitions 111 between projections of two adjacent second partitions 131 .
换言之，沿电池箱底板100的厚度方向，两个第二分隔件131之间设置有两个间隔布置的第一分隔件111。In other words, along the thickness direction of the battery box bottom plate 100 , two first partitions 111 arranged at intervals are disposed between the two second partitions 131 .
减小第二分隔件131的密度，增加相邻两个第二分隔件131之间的距离，有利于避免第二分隔件131对冷却液低温的传递，使尽可能少的热量经过第二分隔件131传递至外边板130。Decreasing the density of the second partitions 131 and increasing the distance between two adjacent second partitions 131 is beneficial to avoid the transfer of low temperature of the cooling liquid by the second partitions 131, so that as little heat as possible passes through the second partitions The pieces 131 are transferred to the outer side panel 130 .
需要说明的是，在本申请的其他实施例中，沿电池箱底板100的厚度方向，相邻两个第二分隔件131的投影之间可以具有三个、四个或者更多个第一分隔件111的投影。It should be noted that, in other embodiments of the present application, along the thickness direction of the battery box bottom plate 100 , there may be three, four or more first partitions between the projections of two adjacent second partitions 131 . Projection of Piece 111.
或者，在本申请的其他实施例中，沿电池箱底板100的厚度方向，相邻两个第一分隔件111的投影之间具有两个第二分隔件131的投影。换言之，相邻两个第一分隔件111之间设置有两个第二分隔件131。在本申请的其他实施例中，相邻两个第一分隔件111之间可以设置三个、四个或者更多个第二分隔件131。Alternatively, in other embodiments of the present application, along the thickness direction of the battery box bottom plate 100 , there are projections of two second partitions 131 between the projections of two adjacent first partitions 111 . In other words, two second partitions 131 are disposed between two adjacent first partitions 111 . In other embodiments of the present application, three, four or more second partitions 131 may be disposed between two adjacent first partitions 111 .
在本实施例中，第一分隔件111、第二分隔件131的厚度相同，即第一分隔件111与第二分隔件131沿与隔板120平行的方向具有相同的尺寸。可以理解的是，在本申请的其他实施例中，第一分隔件111、第二分隔件131沿与隔板120平行的方向的尺寸可以不相同。In this embodiment, the thicknesses of the first spacer 111 and the second spacer 131 are the same, that is, the first spacer 111 and the second spacer 131 have the same size along a direction parallel to the spacer 120 . It can be understood that, in other embodiments of the present application, the dimensions of the first partition member 111 and the second partition member 131 along a direction parallel to the partition plate 120 may be different.
在本实施例中，隔板120与外边板130之间的距离小于隔板120与内边板110之间的距离。换言之，第一分隔件111的高度大于第二分隔件131的高度，从而使第一腔体112的高度大于第二腔体132的高度，使第一腔体112内可以容纳较多的冷却液。In this embodiment, the distance between the partition plate 120 and the outer side plate 130 is smaller than the distance between the partition plate 120 and the inner side plate 110 . In other words, the height of the first partition 111 is greater than the height of the second partition 131 , so that the height of the first cavity 112 is greater than that of the second cavity 132 , so that the first cavity 112 can accommodate more cooling liquid .
在本申请的其他实施例中，隔板120与外边板130之间的距离也可以大于或者等于隔板120与内边板110之间的距离。In other embodiments of the present application, the distance between the partition plate 120 and the outer side plate 130 may also be greater than or equal to the distance between the partition plate 120 and the inner side plate 110 .
