技术领域technical field
本发明涉及功率电池的冷却技术领域，具体涉及一种功率电池的工质接触式冷却系统及其工作方法。The invention relates to the technical field of cooling of power batteries, in particular to a working medium contact cooling system of a power battery and a working method thereof.
背景技术Background technique
随着新能源战略实施，电动汽车正在大规模普及，锂离子动力电池因其优异的功率输出特性和寿命长等优点得到良好应用。但大容量、高功率锂离子电池性能对温度变化较敏感。且在有限空间内，电池使用数目较大。当车辆在不同行驶状况下运行时，电池会以不同倍率放电，以不同生热速率产生大量热量，加上时间累积以及空间影响会产生不均匀热量聚集，从而导致电池组运行环境温度复杂多变。0℃以下的低温环境容易在电部件启动过程中造成电池损毁；而长期高温环境会缩减电池容量，如果长时间积累，会造成部分电池过充电和过放电，进而影响电池的寿命与性能，极易产生爆炸、燃烧等安全隐患。With the implementation of the new energy strategy, electric vehicles are being popularized on a large scale, and lithium-ion power batteries are well used because of their excellent power output characteristics and long life. However, the performance of large-capacity and high-power lithium-ion batteries is sensitive to temperature changes. And in a limited space, the number of batteries used is relatively large. When the vehicle is running under different driving conditions, the battery will be discharged at different rates, and a large amount of heat will be generated at different heat generation rates. In addition to the accumulation of time and the influence of space, uneven heat accumulation will result, resulting in complex and changeable operating environment temperature of the battery pack. . A low temperature environment below 0°C will easily cause battery damage during the start-up process of electrical components; and a long-term high temperature environment will reduce the battery capacity. If it accumulates for a long time, it will cause some batteries to be overcharged and overdischarged, which will affect the life and performance of the battery. It is easy to cause safety hazards such as explosion and combustion.
因此，高功率动力电池在工作时产生的热量必须经过冷却装置散热，确保电池温度在其安全工作要求温度范围内，避免超温造成安全隐患。Therefore, the heat generated by the high-power power battery must be dissipated by the cooling device to ensure that the battery temperature is within the temperature range required for safe operation, and avoid potential safety hazards caused by over-temperature.
现有的功率电池冷却装置，存在如下技术缺陷：The existing power battery cooling device has the following technical defects:
(1)利用空气作为介质，进行间接传热：①冷却装置采用强制对流空气冷却，利用风扇/风机强制环境空气对流进行散热，而空气的热传导性能低于液体工质热传导性能，散热效率低。②对空气的洁净度提出更高要求。(1) Use air as a medium for indirect heat transfer: ①The cooling device adopts forced convection air cooling, and uses fans/fans to force ambient air convection to dissipate heat. However, the thermal conductivity of air is lower than that of liquid working fluid, and the heat dissipation efficiency is low. ② Put forward higher requirements on the cleanliness of the air.
(2)在电池系统内设置导热管，进行间接传热：①依靠导热管内循环的液体工质与发热的电池进行热交换，此方法虽然采用液态工质进行传热，但工质与电池仍然为间接接触，存在热阻、流阻及流动不均匀问题，散热效率低。②需要依据电池排布情况设计导热管回路，导热管回路排布困难，占用空间大。(2) Install heat pipes in the battery system for indirect heat transfer: ①Rely on the liquid working medium circulating in the heat pipe to exchange heat with the heating battery. Although this method uses liquid working medium for heat transfer, the working medium and the battery are still For indirect contact, there are problems of thermal resistance, flow resistance and uneven flow, and the heat dissipation efficiency is low. ② It is necessary to design the heat pipe circuit according to the arrangement of the batteries. The heat pipe circuit is difficult to arrange and takes up a lot of space.

3、工质箱设有水循环冷却装置：水循环冷却装置的蒸发工作端浸入工质箱中，水循环冷却装置的管路设有水泵，水循环冷却装置的散热端通过风扇进行鼓风。3. The working medium box is equipped with a water circulation cooling device: the evaporation working end of the water circulation cooling device is immersed in the working medium box, the pipeline of the water circulation cooling device is equipped with a water pump, and the cooling end of the water circulation cooling device is blown by a fan.
4、工质箱设有压缩式制冷循环冷却装置：压缩式制冷循环冷却装置的蒸发器浸于工质箱中，外侧的冷凝器散热。4. The working medium box is equipped with a compression refrigeration cycle cooling device: the evaporator of the compression refrigeration circulation cooling device is immersed in the working medium box, and the outer condenser dissipates heat.
上述的功率电池的工质接触式冷却系统的工作方法，所述工质泵启动，绝缘液体导热工质通过过滤器进入工质泵，工质泵把绝缘液体导热工质输送到喷淋总管，喷淋总管把绝缘液体导热工质分配到各个喷淋支管，喷嘴喷出的绝缘液体导热工质直接喷淋到高功率电池组的四周及上方，高功率电池组的热量通过绝缘液体导热工质带走，绝缘液体导热工质在重力作用下回流到工质箱并被冷却，如此循环，绝缘液体导热工质不断将高功率电池组的热量带走。In the working method of the working medium contact cooling system of the power battery, the working medium pump is started, the insulating liquid and heat-conducting working medium enters the working medium pump through the filter, and the working medium pump transports the insulating liquid and heat-conducting working medium to the spray main pipe, The spray main pipe distributes the insulating liquid heat-conducting working medium to each spray branch pipe, and the insulating liquid heat-conducting working medium ejected from the nozzle is directly sprayed around and above the high-power battery pack, and the heat of the high-power battery pack passes through the insulating liquid heat-conducting working medium Take away, the insulating liquid heat-conducting working medium returns to the working medium box under the action of gravity and is cooled, and in this cycle, the insulating liquid heat-conducting working medium continuously takes away the heat of the high-power battery pack.
本发明相对于现有技术具有如下的优点：Compared with the prior art, the present invention has the following advantages:
1、喷淋支管和喷淋总管形成一个笼状框架，高功率电池组放置在笼状框架内，其侧面和上方分布喷淋支管，形成相对开放式的喷淋结构，绝缘液体导热工质直接与需要散热的高功率电池组发热表面接触传导热量，降低接触热阻，没有任何中间介质和传热转换环节，提高热传导效率。1. The spray branch pipe and the spray main pipe form a cage-like frame. The high-power battery pack is placed in the cage-like frame, and the spray branch pipes are distributed on the side and above to form a relatively open spray structure. The insulating liquid and heat-conducting working medium are directly It conducts heat in contact with the heating surface of the high-power battery pack that needs to dissipate heat, reducing contact thermal resistance, without any intermediate medium and heat transfer conversion link, and improving heat transfer efficiency.
2、绝缘液体导热工质为非极性物质，喷淋过程中绝缘液体导热工质无相变，喷淋的绝缘液体导热工质在高功率电池组表面形成雾化液膜，雾化液膜热传导具有小流量、大温差、高传热系数、高热流密度等优良传热及流动的综合特性。2. The heat-conducting working medium of the insulating liquid is a non-polar substance, and there is no phase change in the heat-conducting working medium of the insulating liquid during the spraying process. The sprayed heat-conducting working medium of the insulating liquid forms an atomized liquid film on the surface of the high-power battery pack, and the atomized liquid film Heat conduction has comprehensive characteristics of excellent heat transfer and flow such as small flow rate, large temperature difference, high heat transfer coefficient, and high heat flux density.

4、采用喷淋式散热，绝缘液体导热工质与高功率电池组发热面有效接触面积(换热面积)会增加，从而理论热传导效率会提高(换热量与面积成正比关系)，绝缘液体导热工质有效利用率更高。4. With spray heat dissipation, the effective contact area (heat exchange area) between the insulating liquid heat-conducting working medium and the heating surface of the high-power battery pack will increase, so that the theoretical heat conduction efficiency will increase (the heat exchange amount is proportional to the area), and the insulating liquid The effective utilization rate of heat-conducting working medium is higher.
5、喷淋过程中绝缘液体导热工质无相变，因此系统循环不需要气相工质回收设备，只需设置常见过滤器用于过滤工质在相对开放式循环过程中产生的杂质，系统自适应性及可靠性更高。5. There is no phase change of the insulating liquid and heat-conducting working medium during the spraying process, so the system circulation does not require gas-phase working medium recovery equipment, and only needs to set up a common filter to filter the impurities generated by the working medium in a relatively open cycle process, and the system is self-adaptive Higher performance and reliability.
6、绝缘液体导热工质为非极性物质，不会对电子、电器设备及回路产生影响，对硬件不会有损坏。6. The heat-conducting working medium of the insulating liquid is a non-polar substance, which will not affect the electronic and electrical equipment and circuits, and will not damage the hardware.
7、喷淋管路结构简单、动力消耗小；喷嘴部件制造技术成熟、可靠性高，传热过程和结构越简单其可靠性和可控性越高。7. The structure of the spray pipeline is simple and the power consumption is small; the manufacturing technology of the nozzle parts is mature and the reliability is high. The simpler the heat transfer process and structure, the higher the reliability and controllability.
8、绝缘液体导热工质作为液体换热方式，其热传导性能普遍优于使用空气强制对流，并且相对于传统强制对流风冷系统需要新风单元以及一些复杂的架构设计，液体冷却技术架构的设计要求本身比较少，直接接触喷淋的结构可以更加简单，从而节约成本和延长器件使用寿命。8. Insulating liquid heat conduction working medium is used as a liquid heat exchange method, and its heat conduction performance is generally better than that of air forced convection, and compared with traditional forced convection air cooling systems, fresh air units and some complex architecture designs are required, and the design requirements of liquid cooling technology architecture The structure itself is relatively small, and the structure of direct contact with the spray can be simpler, thereby saving costs and prolonging the service life of the device.
