具体实施方式Detailed ways

为使本领域技术人员更好地理解本发明的技术方案，下面结合具体实施方式对本发明作进一步详细描述。In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with specific embodiments.

本发明实施例提供了圆柱形动力电池模组，如图1和图2所示，包括换气装置1、通气管2、电池组顶部固定盘3、电池模组4、电池底部固定盘5。The embodiment of the present invention provides a cylindrical power battery module, as shown in FIG. 1 and FIG. 2 , including a ventilation device 1 , an air pipe 2 , a top fixing plate 3 of the battery pack, a battery module 4 , and a bottom fixing plate 5 of the battery.

电池模组4的底面固定在电池底部固定盘5上，电池模组4的顶端固定在电池组顶部固定盘3上，电池模组4由行列整齐排列的圆柱形电池组成，所述圆柱形电池之间的空隙处安装通气管2，如图3和图5所示。The bottom surface of the battery module 4 is fixed on the battery bottom fixing plate 5, the top of the battery module 4 is fixed on the battery top fixing plate 3, the battery module 4 is composed of cylindrical batteries arranged in rows and rows, and the cylindrical batteries Air pipe 2 is installed in the gap between, as shown in Figure 3 and Figure 5.

通气管2的管身上设置通孔，如图4所示，通孔也包括椭圆形、菱形、长方形，如图10所示，通气管2一端密闭，一端密闭连接换气装置1，换气装置1鼓入气体，气流通过通气管2上的通孔流入电池的间隙中，与电池进行热量交换，然后从电池模组4四侧流出，如图4所示，出口设有排风扇，以此来保持动力电池模组各个电池的温度和温差一致性。The pipe body of vent pipe 2 is provided with through hole, as shown in Figure 4, through hole also comprises ellipse, rhombus, rectangle, as shown in Figure 10, vent pipe 2 one ends are airtight, and one end is airtightly connected ventilator 1, ventilator 1. Gas is blown in, and the airflow flows into the gap of the battery through the through hole on the ventilation pipe 2, exchanges heat with the battery, and then flows out from the four sides of the battery module 4, as shown in Figure 4, and the outlet is provided with an exhaust fan, so as to Keep the temperature and temperature difference consistency of each battery in the power battery module.

换气装置1安装在电池组顶部固定盘3的顶部，电池模组4内部设置温度传感器，当电池模组4内部的温度高于设定值，换气装置1鼓入低温气体，当电池模组4内部的温度低于设定值，换气装置1鼓入高温气体，如图11所示。The ventilator 1 is installed on the top of the fixed plate 3 on the top of the battery pack, and a temperature sensor is installed inside the battery module 4. When the temperature inside the battery module 4 is higher than the set value, the ventilator 1 blows in low-temperature gas. The temperature inside the group 4 is lower than the set value, and the ventilation device 1 blows high-temperature gas, as shown in FIG. 11 .

通气管2上的通孔方向如图7所示，不同的通孔方向可以使得气流散发的方式改变。鼓入高温气体时采用图7(a)的方式，温度能直接传递到电池上去；鼓入低温气体的时候使用图7（b）的方式，能把内部的热量尽量的带出去，有利于系统的效率提高和能量节约。The directions of the through holes on the vent pipe 2 are shown in FIG. 7 , and different directions of the through holes can change the way the airflow is distributed. When blowing high-temperature gas, use the method shown in Figure 7(a), and the temperature can be directly transferred to the battery; when blowing low-temperature gas, use the method shown in Figure 7(b), which can take out the internal heat as much as possible, which is beneficial to the system. Efficiency improvements and energy savings.

由于单体圆柱电池放电时电池顶部的温度过高，而电池中间温度最低，因此可以在通气管2顶部设置较多的通孔，中间位置设置较少的通孔；或者顶部的通孔直径增大，中间的通孔直径减小，如图8所示。Because the temperature at the top of the battery is too high when the single cylindrical battery is discharged, and the temperature in the middle of the battery is the lowest, so more through holes can be arranged at the top of the vent pipe 2, and fewer through holes can be arranged at the middle position; or the diameter of the through holes at the top can be increased. Larger, the diameter of the through hole in the middle decreases, as shown in Figure 8.

通气管2进口出口交错设置，如图9所示，能增加对流换热面积，提高换热效率，电池模组4温度过高时，冷空气能更有效的温度，当电池模组4温度高低时，通热空气能更有效的提高温度，以使电池模组4保持在最优的温度范围内工作。The inlet and outlet of the ventilation pipe 2 are arranged staggeredly, as shown in Figure 9, which can increase the convective heat transfer area and improve the heat transfer efficiency. When the temperature of the battery module 4 is too high, the cold air can cool the temperature more effectively. When , the heated air can increase the temperature more effectively, so that the battery module 4 can keep working within the optimal temperature range.

本发明的有益效果是：The beneficial effects of the present invention are:
