Description

一种电池冷却装置A battery cooling device

技术领域technical field

本发明涉及电动汽车、油电混合动力汽车、或者燃料电池汽车动力蓄电池换热设备领域，尤其涉及一种电池冷却装置。The invention relates to the field of heat exchange equipment for power storage batteries of electric vehicles, gasoline-electric hybrid vehicles, or fuel cell vehicles, and in particular to a battery cooling device.

背景技术Background technique

动力电池作为电动汽车的动力来源，是提高整车性能和降低成本的关键一环，其温度特性直接影响汽车的性能、寿命和耐久性，锂离子电池因比能大、循环寿命长、自放电率低、允许工作温度范围宽、低温效应好等优点作为目前首选的动力蓄电池，因此保证电池内各个单电池工作在合理温度范围内的同时需维持各个电池之间的温度均匀性。目前采用的电池冷却方式主要由液体冷却和风冷却，风冷却是通过运动产生的风将电池的热量经过排风风扇带走，但是该冷却方式不适合用于高放电倍率和高温的运行环境中。As the power source of electric vehicles, power batteries are a key part of improving vehicle performance and reducing costs. Their temperature characteristics directly affect the performance, life and durability of vehicles. Lithium-ion batteries have large specific energy, long cycle life, and Low efficiency, wide allowable operating temperature range, good low temperature effect and other advantages are currently the preferred power battery. Therefore, it is necessary to maintain the temperature uniformity among each battery while ensuring that each single battery in the battery works within a reasonable temperature range. The currently used battery cooling methods are mainly liquid cooling and wind cooling. Wind cooling is to take the heat of the battery away through the exhaust fan through the wind generated by movement. However, this cooling method is not suitable for high discharge rate and high temperature operating environments.

液冷却系统如图1所示，在水泵D的驱动下冷却液体流经换热器C和电池包A底部的电池导热板B，将电池内部的热量导出，但电池内部的热量需要通过电池内的电极和电解质将热量沿竖直方向传递到电池底部的电池导热板B上，热传导路径长，导致传热热阻大、换热效率低、竖直方向的温差较大、对外部冷却系统性能要求较苛刻；且电池导热板B内部的冷却液体是依次流过每个电池包A底部，流经每个电池导热板B的冷却液体温度不一致，从而导致电池包A与电池包A之间的温差较大，无法保证电池与电池之间的温度的均匀性。The liquid cooling system is shown in Figure 1. Driven by the water pump D, the cooling liquid flows through the heat exchanger C and the battery heat conducting plate B at the bottom of the battery pack A to dissipate the heat inside the battery. The electrodes and electrolyte in the battery transfer heat to the battery heat conducting plate B at the bottom of the battery in the vertical direction. The heat conduction path is long, resulting in large heat transfer resistance, low heat transfer efficiency, large temperature difference in the vertical direction, and negative impact on the performance of the external cooling system. The requirements are more stringent; and the cooling liquid inside the battery heat conduction plate B flows through the bottom of each battery pack A in turn, and the temperature of the cooling liquid flowing through each battery heat conduction plate B is inconsistent, resulting in a gap between the battery pack A and the battery pack A. The temperature difference is large, and the uniformity of temperature between batteries cannot be guaranteed.
