The air in the assembly space is extracted by controlling the operation of the plurality of exhaust fans 219, thereby ensuring the ventilation and heat dissipation effect of the assembly space.

[0051] like Figure 1 to Figure 2As shown, the ends of the plurality of ventilation assembly pipes 218 outside the energy storage box 1 are all fixedly equipped with dust filter screens 220. The dust filter screens 220 are used to protect the exhaust fan 219 from dust.

[0052] like Figures 4 to 8 As shown, the air cooling and heat dissipation mechanism 3 is fixedly mounted below the energy storage box 1, and the air cooling and heat dissipation mechanism 3 includes a flow guiding base 301, which is fixedly mounted below the energy storage box 1. The flow guiding base 301 guides and transports the gas generated during the operation of the cooling fan 304.

[0053] like Figures 7 and 8 As shown, ventilation pipes 302 are fixedly connected to both sides of the flow guide base 301. The ventilation pipes 302 play the role of connecting the flow expansion pipe 303 and the flow guide base 301.

[0054] like Figures 7 and 8 As shown, one end of the ventilation pipe 302 outside the flow guide base 301 is fixedly connected to a flow expansion pipe 303. The flow expansion pipe 303 plays the role of assembling and fixing the heat dissipation fan 304 and guiding the airflow.

[0055] like Figures 7 and 8 As shown, one end of the diffuser 303 away from the ventilation pipe 302 is fixedly equipped with multiple groups of evenly distributed cooling fans 304. By controlling the operation of the multiple groups of cooling fans 304, the outside air can be transported into the guide base 301 under the action of the cooling fans 304.

[0056] Specifically, a plurality of evenly distributed ventilation bottom holes 208 are provided above the flow guide base 301, and the ventilation bottom holes 208 are arranged corresponding to the porous supporting bottom plate 203. The porous supporting bottom plate 203 and the flow guide base 301 are conveniently connected and conducted through the plurality of ventilation bottom holes 208, so that the air in the flow guide base 301 can be transported to the assembly space along the ventilation bottom holes 208, the porous supporting bottom plate 203, and the supporting filter plate 204, so as to facilitate heat dissipation and cooling of the energy storage batteries placed in the assembly space.

[0059] During specific use, the temperature in the energy storage box 1 can be detected in real time by setting a temperature sensor in the energy storage box 1. When the energy storage battery in the energy storage box 1 needs to be cooled, the operation of the cooling fan 304 can be controlled so that the outside air is transported to the guide base 301 along the diffuser pipe 303 and the ventilation pipe 302. The air in the guide base 301 can be transported to the liquid cooling partition 201 under the action of the air inlet hole 206, and transported to the assembly space along the exhaust holes on both sides of the liquid cooling partition 201, so as to dissipate heat and cool the side surfaces of the energy storage battery in the assembly space.

[0060] At the same time, the air in the guide base 301 can be transported from bottom to top into the assembly space along the ventilation bottom hole 208, the porous supporting bottom plate 203, and the supporting filter plate 204, and the energy storage batteries placed in the assembly space are cooled by air by transporting air from bottom to top.

[0061] When the temperature in the energy storage box 1 continues to rise, the low-temperature heat exchange liquid in the liquid storage tank 209 can be extracted by controlling the operation of the bottom circulation liquid pump 210, and the low-temperature heat exchange liquid is transported to the liquid-cooled heat exchange tube 202 along the lower liquid inlet pipe 212. The low-temperature heat exchange liquid circulates in the liquid-cooled heat exchange tube 202, which not only cools the liquid-cooled partition 201, but also assists in cooling the air transported in the liquid-cooled partition 201.

[0062] In addition, the low-temperature heat exchange liquid in the liquid storage tank 209 can be extracted by controlling the operation of the side circulating liquid pump 214, so that the low-temperature heat exchange liquid circulates along the side extraction pipe 215, the bottom heat exchange pipe 205 and the side inlet pipe 216 at the bottom of the assembly space. The low-temperature heat exchange liquid circulates in the bottom heat exchange pipe 205, which can not only liquid-cool the supporting filter plate 204, but also assist in cooling the air transported at the bottom of the assembly space. By using multiple ways of heat dissipation and temperature reduction, the energy storage battery placed in the energy storage box 1 can be intelligently temperature-controlled, which improves the stability of the energy storage battery.
