本申请属于电池模组冷却技术领域，尤其涉及一种冷却板组件。The present application belongs to the technical field of battery module cooling, and in particular, relates to a cooling plate assembly.
背景技术Background technique
冷却板通常和电池模组接触，用于和电池模组进行热交换，冷却电池模组的电芯，防止电池模组过热，导致电池模组工况不佳。The cooling plate is usually in contact with the battery module and is used to perform heat exchange with the battery module, cool the battery cells of the battery module, and prevent the battery module from overheating, which would cause the battery module to operate in poor condition.
参见图7所示，现有的冷却板通常仅有一路水道，水道呈多次往复弯折延伸。水道在延伸过程中可以并列分割出多条子流道，各子流道相邻设置，水道总体路径呈M形，水道结构设计单一，流场不均衡。一般电池模组中间温度最高，外圈温度较低。若电池模组采用上述的冷却板冷却则容易出现因为冷却板内流场不均衡导致冷却板对电池模组的电芯温度调节不均衡的问题。As shown in Figure 7, the existing cooling plate usually has only one water channel, and the water channel extends in multiple reciprocating bends. During the extension process, the water channel can be divided into multiple sub-channels in parallel, and each sub-channel is arranged adjacent to each other. The overall path of the water channel is M-shaped, the water channel structure design is single, and the flow field is unbalanced. Generally, the temperature in the middle of the battery module is the highest, and the temperature of the outer circle is lower. If the battery module is cooled by the above-mentioned cooling plate, it is easy to have the problem of uneven adjustment of the battery cell temperature of the battery module by the cooling plate due to the unbalanced flow field in the cooling plate.
有鉴于此，特提出本发明。In view of this, the present invention is proposed.

实施例一Embodiment 1
参见图1至图6所示，本申请实施例提供一种冷却板组件，包括：中部水道11和外侧水道。中部水道11位于冷却板组件中部位置，所述中部水道11沿第一方向往复弯折延伸，在冷却板上中部水道11总体沿第二方向分布。换句话说，中部水道11也可以被认为是沿第二方向延伸，且在沿第二方向上，中部水道11还沿第一方向往复弯折。在不同的观察角度可对该中部水道11做不同的描述，但是所要表达的中部水道11的结构是统一的。外侧水道位于所述冷却板组件的边沿位置，所述外侧水道沿所述中部水道11的周侧延伸。中部水道11和外侧水道是相并联的两个水道。进入冷却板组件的冷却水分两路分别进入外侧水道和中部水 道11，经过外侧水道的冷却水不会再进入中部水道11，进入中部水道11的冷却水也不会再进入外侧水道。As shown in Figures 1 to 6, an embodiment of the present application provides a cooling plate assembly, including: a middle water channel 11 and an outer water channel. The middle water channel 11 is located in the middle of the cooling plate assembly, and the middle water channel 11 extends and bends back and forth along a first direction, and the middle water channel 11 is generally distributed along a second direction on the cooling plate. In other words, the middle water channel 11 can also be considered to extend along the second direction, and along the second direction, the middle water channel 11 also bends back and forth along the first direction. The middle water channel 11 can be described differently at different observation angles, but the structure of the middle water channel 11 to be expressed is unified. The outer water channel is located at the edge of the cooling plate assembly, and the outer water channel extends along the circumference of the middle water channel 11. The middle water channel 11 and the outer water channel are two water channels connected in parallel. The cooling water entering the cooling plate assembly enters the outer water channel and the middle water channel in two ways, respectively. Channel 11, the cooling water passing through the outer water channel will not enter the middle water channel 11 again, and the cooling water entering the middle water channel 11 will not enter the outer water channel again.
一般电池模组中间温度最高，外圈温度较低，本冷却板具有中部水道11和外侧水道，外侧水道沿冷却板组件的边沿延伸，用于对电池模组的外圈进行冷却，中部水道11分布于冷却板的中部位置，用于对电池模组的中部进行冷却。对比图6和图7可知，本申请冷却板组件内水道的结构设置相对于传动水道结构，更加利于流场均衡，利于达到电池模组温度均衡。Generally, the temperature in the middle of the battery module is the highest, and the temperature in the outer ring is lower. The cooling plate has a middle water channel 11 and an outer water channel. The outer water channel extends along the edge of the cooling plate assembly and is used to cool the outer ring of the battery module. The middle water channel 11 is distributed in the middle position of the cooling plate and is used to cool the middle of the battery module. Comparing Figures 6 and 7, it can be seen that the structural setting of the water channel in the cooling plate assembly of the present application is more conducive to flow field balance than the transmission water channel structure, and is conducive to achieving temperature balance of the battery module.
本申请的冷却板组件可根据模组发热情况进行设计通过改变水道宽度，调节中部水道11和外侧水道的换热面积调整流场，可对不同电池模组的电芯进行均衡降温。The cooling plate assembly of the present application can be designed according to the heating conditions of the module.

第一方向和第二方向相垂直，两者可以分别为冷却板组件的长度方向和宽度方向。本申请实施例中，在中部水道11的两侧分别设置两个侧部水道，两个侧部水道相连通，进入侧部水道的冷却液直接和电池模组外圈进行换热，冷却液不是经过电池模组的内圈换热后再和电池模组的外圈进行换热，冷却效率更高，利于电池模组的温度均衡。The first direction and the second direction are perpendicular, and the two can be the length direction and the width direction of the cooling plate assembly, respectively. In the embodiment of the present application, two side water channels are respectively arranged on both sides of the middle water channel 11, and the two side water channels are connected. The coolant entering the side water channels directly exchanges heat with the outer ring of the battery module, and the coolant does not exchange heat with the inner ring of the battery module before exchanging heat with the outer ring of the battery module. The cooling efficiency is higher, which is conducive to the temperature balance of the battery module.
