本发明解决了背景技术中存在的缺陷，本发明具备以下有益效果：The present invention solves the defects existing in the background technology and has the following beneficial effects:

（1）本发明通过在储能柜的内部设置电池舱，电池舱与储能柜外壳体侧壁之间设置有输风通道，储能柜底部设置有空调机，空调机上设置第一排风板与第二排风板并扣合而成冷风通道，电池舱内的多个电池模组皆设置有风冷箱，风冷箱冷风入口与冷风通道连通，风冷箱热风出口与输风通道连通，同时储能柜顶部设置有循环风机。在运行时，空调制冷将冷气通过冷风通道传输至电池舱内，并且通过各个电池模组内的风冷箱将冷风输送进电蓄电池表面，并对蓄电池进行降温，一个空调机工作即可实现同时对多组电池模组进行制冷，形成一对多的风冷系统，利用单个空调机结合多个排风道的设计，节省了空调机数量的使用，减轻制造成本，多个排风道的贴合电池模组的设计，不占用蓄电池的安装空间，相较于现有技术中一对一的制冷方式，节省能量损耗的同时还减少内部零件，从而减少占地面积，减轻储能柜整体体积。(1) The present invention provides a battery compartment inside the energy storage cabinet, an air supply channel is provided between the battery compartment and the side wall of the outer shell of the energy storage cabinet, an air conditioner is provided at the bottom of the energy storage cabinet, a first exhaust plate and a second exhaust plate are provided on the air conditioner and are buckled to form a cold air channel, multiple battery modules in the battery compartment are all provided with an air cooling box, the cold air inlet of the air cooling box is connected to the cold air channel, the hot air outlet of the air cooling box is connected to the air supply channel, and a circulating fan is provided on the top of the energy storage cabinet. During operation, the air conditioning refrigeration transmits cold air to the battery compartment through the cold air channel, and transmits cold air to the surface of the battery through the air cooling box in each battery module to cool the battery. One air conditioner can cool multiple groups of battery modules at the same time, forming a one-to-many air cooling system. The design of a single air conditioner combined with multiple exhaust ducts saves the number of air conditioners and reduces manufacturing costs. The design of multiple exhaust ducts that fit the battery module does not occupy the installation space of the battery. Compared with the one-to-one cooling method in the prior art, it saves energy loss and reduces internal parts, thereby reducing the footprint and the overall volume of the energy storage cabinet.

（2）制冷过程中打开循环风机，由于冷空气经过蓄电池被进行换热，从而使经过风冷箱后的空气得到升温，升温后的空气从风冷箱内流出至热风通道后受循环风机影响由输出通道排出，向下输送回蒸发器中再次进行降温，降温后的冷空气重新又回到冷风通道，再次通过内循环风道对电池模组进行降温。通过内循环风道输送冷风，外循环风道回风的设计方式，使储能柜内部整体结构紧密，且空气在经过电池模组升温后立即得到蒸发器的降温，并重新返回电池模组内部的风冷箱内部进行换热，可以有效的提高对电池模组的散热效果。(2) During the refrigeration process, the circulating fan is turned on. As the cold air passes through the battery for heat exchange, the air passing through the air cooling box is heated. The heated air flows out of the air cooling box to the hot air channel and is discharged from the output channel under the influence of the circulating fan. It is then transported back to the evaporator for cooling again. The cooled cold air returns to the cold air channel and cools the battery module again through the internal circulation duct. The design of conveying cold air through the internal circulation duct and returning air through the external circulation duct makes the overall structure of the energy storage cabinet tight, and the air is immediately cooled by the evaporator after being heated by the battery module, and returns to the air cooling box inside the battery module for heat exchange, which can effectively improve the heat dissipation effect on the battery module.

（3）本发明通过设置在电池模组内设置风冷箱，并将储能电池设置在风冷箱内，通过风冷箱上设置的冷风入口和热风出口形成散热风道，散热风道由箱体底部向箱体上部延伸，从而在散热过程中冷空气对储能电池采用将蓄电池包裹的散热方式，极大的提高了散热效率，同时采用风冷直接包裹蓄电池的散热方式，可直接通过导热垫、散热板对每个电芯进行散热，从而提高了电芯温度的一致性，避免了电芯温度过高，延长了电芯的使用寿命。(3) The present invention arranges an air cooling box in the battery module, and arranges the energy storage battery in the air cooling box, and forms a heat dissipation duct through the cold air inlet and hot air outlet arranged on the air cooling box. The heat dissipation duct extends from the bottom of the box to the upper part of the box. Therefore, during the heat dissipation process, the cold air wraps the energy storage battery in a heat dissipation manner, which greatly improves the heat dissipation efficiency. At the same time, the heat dissipation manner of directly wrapping the battery in air cooling can directly dissipate heat for each battery cell through the thermal pad and the heat dissipation plate, thereby improving the consistency of the battery cell temperature, avoiding excessively high battery cell temperature, and extending the service life of the battery cell.

During operation, the air conditioning refrigeration transmits cold air to the battery compartment 12 through the cold air channel 43, and transmits cold air to the surface of the battery through the air cooling box 121 in each battery module 120 to cool the battery. One air conditioner 41 can cool multiple groups of battery modules 120 at the same time, forming a one-to-many air cooling system. The design of a single air conditioner 41 combined with multiple exhaust ducts saves the number of air conditioners 41 and reduces manufacturing costs.

The circulation fan 53 is connected to the hot air channel and transports the hot air in the hot air channel to the air conditioner 41.

制冷过程中打开循环风机53，由于冷空气经过蓄电池被进行换热，从而使经过风冷箱121后的空气得到升温，升温后的空气从风冷箱121内流出至热风通道后受循环风机53影响由输出通道排出，向下输送回蒸发器4100中再次进行降温，降温后的冷空气重新又回到冷风通道43，再次通过内循环风道4对电池模组120进行降温。通过内循环风道4输送冷风，外循环风道5回风的设计方式，使储能柜1内部整体结构紧密，且空气在经过电池模组120升温后立即得到蒸发器4100的降温，并重新返回电池模组120内部的风冷箱121内部进行换热，可以有效的提高对电池模组120的散热效果。During the refrigeration process, the circulating fan 53 is turned on.

Therefore, during the heat dissipation process, the cold air wraps the energy storage battery in a heat dissipation manner, which greatly improves the heat dissipation efficiency. At the same time, the heat dissipation manner of directly wrapping the battery with air cooling can directly dissipate heat for each battery cell through the thermal pad and the heat dissipation plate, thereby improving the consistency of the battery cell temperature, avoiding excessive temperature of the battery cell, and extending the service life of the battery cell.
