[0043] In one embodiment, Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, a wind guide structure is provided, which is applied to an energy storage container 10.

[0044] Among them, the energy storage container 10 can be an AC / DC integrated energy storage container 10. The energy storage container 10 is provided with a battery compartment 110, each battery cluster 114 is arranged inside the battery compartment 110, and the air conditioning device 112 can be arranged on the inner wall of the battery compartment 110, for example, the air conditioning device 112 can be suspended on the inner wall of the battery compartment 110. The air conditioning device 112 is provided with a cold air output terminal, and the air conditioning device 112 is used to output cold air to cool each battery cluster 114. In another example, the air conditioning device 112 can also be used to output hot air to keep each battery cluster warm when the external environment is low.

[0045] The energy storage container 10 is also provided with an electrical compartment 120, which is isolated from the battery compartment 110.

The junction box can be used for current convergence and power distribution, and can converge the current of the battery cluster 114 and the current of other power sources and then output them to the power grid to meet the power contribution of the mains power grid. The energy storage converter can control the charging and discharging process of the battery cluster 114, perform AC-DC conversion, and directly supply power to the AC load without the need for the power grid. The power distribution cabinet refers to the control cabinet of the container, and the fire fighting equipment is used to output fire fighting agents to the electrical compartment 120 to extinguish fires in the electrical compartment 120. Exemplarily, the fire fighting equipment can also be used to output fire fighting agents to the battery compartment 110 to extinguish fires in the battery compartment 110. The electrical compartment 120 can also be provided with an EMS control cabinet, which can collect the real-time power status of the system and monitor the changes in load power in real time.

[0046] It should be noted that at least one air guide structure 20 may be provided in the energy storage container 10. For example, the air guide structure 20 may be provided in the battery compartment 110. The air guide structure 20 is used to distribute the cold air output by the air-conditioning equipment 112 to each battery cluster 114, so as to evenly distribute the cold air to each battery cluster 114, thereby cooling each battery cluster 114.

[0047] The air guide structure 20 can be divided into an input channel 210 and an output channel group 220, and the input channel 210 and the output channel group 220 can be an integrally formed structure. In another example, the input channel 210 and the output channel group 220 can also be spliced ​​by welding, riveting, bonding or screwing. A shunt component 214 is provided in the input channel 210, and the shunt component 214 divides the input channel 210 into a plurality of input sub-channels 212, and the input port of each input sub-channel 212 is respectively connected to the cold air output end of the air conditioning device 112, and the output port of each input sub-channel 212 is respectively connected to the input port of the corresponding output channel 222, and the output port of each output channel 222 is connected to the corresponding battery cluster 114, so that the cold air output by the air conditioning device 112 can be transmitted to the corresponding battery cluster 114 after passing through the input sub-channel 212 and the output channel 222, and each battery cluster 114 is cooled and cooled, so that each battery cluster 114 is evenly distributed with a corresponding amount of cold air. Exemplarily, the flow dividing component 214 and the input channel 210 may be an integrally formed structure. In another example, the flow dividing component 214 may be disposed in the input channel 210 by bonding, welding, clamping, or screwing.

[0048] The number of output channels 222 of the same air guide structure 20 is the same as the number of input sub-channels 212. A guide assembly 224 is provided in the output channel 222, and the guide assembly 224 can divide the space in the output channel 222, guide the cold air in the output channel 222 to be transmitted to the corresponding battery cluster 114, and the guide assembly 224 can also distribute the cold air in the output channel 222, so that the cold air in the output channel 222 is evenly distributed and output to the corresponding battery cluster 114, so as to avoid uneven cold air output at the output port of the output channel 222, which causes the temperature rise and temperature difference of the battery cluster 114 to exceed reasonable values.

[0049] Exemplarily, the guide component 224 can be disposed near the middle position of the output channel 222 to divide the output channel 222 into two output channels, thereby distributing the cold air to the two output channels for transmission, thereby achieving uniform cold air output from the two output channels and improving uniform cooling of the battery cluster 114 .

[0050] In the above-mentioned embodiment, a diverter component 214 is provided in the input channel 210 of the air guide structure 20 to divide the input channel 210 into a plurality of input sub-channels 212; each input sub-channel 212 is connected to the cold air output end of the air-conditioning device 112; the output channel group 220 includes a plurality of output channels 222; each output channel 222 is connected to each input sub-channel 212 in a one-to-one correspondence, and each output channel 222 is connected to each battery cluster 114 in a one-to-one correspondence; a diverter component 224 is provided in the output channel 222 to distribute and guide the cold air in the output channel 222 to the corresponding battery cluster 114, so as to evenly distribute the cold air output by the air conditioner, and timely and evenly cool down each battery cluster 114 in the battery compartment 110. The present application optimizes and improves the air guide structure 20, and sets a diversion component 214 in the input channel 210 to divide the input channel 210 into a plurality of input sub-channels 212, so that the cold air output by the air-conditioning equipment 112 can be transmitted to the corresponding output channel 222 through the input sub-channel 212; a diversion component 224 is set in the output channel 222 to guide the cold air in the output channel 222 and redistribute it to the corresponding battery cluster 114, so that the cold air output by the output channel 222 can be evenly blown to the corresponding battery cluster 114, so that the cold air of the output channel 222 is evenly distributed, ensuring that the temperature rise and temperature difference of the system battery are within a reasonable range, thereby improving the system life.

[0051] In one embodiment, Figure 1 As shown, the output port size of the output channel 222 is larger than the input port size of the output channel 222 .

[0052] The size of the output port of the output channel 222 can be determined according to the size of the battery cluster 114, and the output port of the output channel 222 faces the corresponding battery cluster 114. For example, the air guide structure 20 can be arranged above the battery cluster 114, and the air conditioning device 112 can be arranged on the side wall of the energy storage container 10. The air conditioning device 112 is arranged adjacent to the air guide structure 20, and the air outlet direction of the output port of the output channel 222 is arranged at a certain angle to the air inlet direction of the input port of the output channel 222.

[0053] By setting the size of the output port of the output channel 222 to be larger than the size of the input port of the output channel 222 , it is helpful to reduce the overall volume of the air guide structure 20 , while at the same time being able to satisfy the requirement of transmitting the cold air output by the output channel 222 to the corresponding battery cluster 114 , thereby achieving cooling of the battery cluster 114 .

[0054] In one embodiment, Figure 1 and Figure 3As shown, the guide assembly 224 includes a first guide plate 2242 ; a first end of the first guide plate 2242 is disposed adjacent to an input port of the output channel 222 , and a second end of the first guide plate 2242 is disposed adjacent to an output port of the output channel 222 .

[0055] The first guide plate 2242 may be in a plate-like structure. The first guide plate 2242 may be arranged in the output channel 222 by bonding, welding, clamping or screwing. Exemplarily, the output channel 222 may be divided into an output air trough and a cover body, and the output air trough and the cover body enclose the output channel 222.

[0056] The battery cluster 114 may be composed of a plurality of stacked battery packs. For example, each layer of battery packs may be arranged in a plurality of rows and two columns. By arranging the first guide plate 2242 in the output channel 222, one side of the first guide plate 2242 fits the bottom of the output air slot, and the other side of the first guide plate 2242 fits the cover body, and by arranging the first end of the first guide plate 2242 adjacent to the input port of the output channel 222 and the second end of the first guide plate 2242 adjacent to the output port of the output channel 222, the space in the output channel 222 can be divided into two output flow channels, and the cold air in the output channel 222 is guided to be dispersedly transmitted to the corresponding battery cluster 114 through the two output flow channels respectively, so that each column of battery packs in the battery cluster 114 can receive the cold air, and the cold air in the output channel 222 is distributed and output, so that the cold air of the output channel 222 is evenly output to the corresponding battery cluster 114, so as to avoid uneven cold air output at the output port of the output channel 222, which causes the temperature rise and temperature difference of the battery cluster 114 to exceed reasonable values, thereby achieving uniform cold air output from the output channel 222 and improving uniform cooling of the battery cluster 114.

[0057] In one embodiment, Figure 1 and Figure 3 As shown, the guide assembly 224 also includes a second guide plate 2244; the first end of the second guide plate 2244 is arranged adjacent to the input port of the output channel 222, and the second end of the second guide plate 2244 is arranged adjacent to the output port of the output channel 222; the first end of the second guide plate 2244 is connected to the first end of the first guide plate 2242, and a first preset angle is formed between the second guide plate 2244 and the first guide plate 2242.

[0058] The second guide plate 2244 is a plate-shaped structure and can be arranged in the output channel 222 by bonding, welding, clamping or screwing.

[0059] The second guide plate 2244 is disposed in the output channel 222, one side of the second guide plate 2244 is in contact with the bottom of the output air slot, and the other side of the second guide plate 2244 is in contact with the cover body. For example, the second guide plate 2244 and the first guide plate 2242 are integrally formed, and the second guide plate 2244 and the first guide plate 2242 can be formed by bending, so that a first preset angle is formed between the second guide plate 2244 and the first guide plate 2242. Exemplarily, the first preset angle is any value between 8 degrees and 10 degrees. For example, the first preset angle can be set to 9 degrees. Since the battery cluster 114 includes a plurality of battery packs, each battery pack is arranged in a preset regular pattern, and there is usually a certain gap between two adjacent battery packs. By providing a first guide plate 2242 and a second guide plate 2244, and a preset angle between the first guide plate 2242 and the second guide plate 2244, the first guide plate 2242 can guide part of the cold air to blow more concentratedly toward the battery pack on one side of the same battery cluster 114, and the second guide plate 2244 can guide part of the cold air to blow more concentratedly toward the battery pack on the other side of the same battery cluster 114. Compared with using only the first guide plate 2242, the first guide plate 2242 and the second guide plate 2244 are combined in this embodiment, which can further improve the uniformity of the cold air distribution output by the output channel 222, so that the cold air output by the output channel 222 can be evenly and concentratedly blown to the corresponding battery cluster 114, ensuring that the temperature rise and temperature difference of the system battery are within a reasonable range.

[0060] By connecting the first end of the second guide plate 2244 to the first end of the first guide plate 2242, and the first end of the second guide plate 2244 is arranged adjacent to the input port of the output channel 222, and the second end of the second guide plate 2244 is arranged adjacent to the output port of the output channel 222, the space in the output channel 222 can be divided into two output flow channels, so that the first guide plate 2242 can guide part of the cold air to be transmitted in one output flow channel, and blow the cold air to one side of the corresponding battery cluster 114, and the second guide plate 2244 can guide part of the cold air to be transmitted in the other output flow channel, and blow the cold air to the other side of the corresponding battery cluster 114, so that each column of battery packs included in the battery cluster 114 can be allocated with cold air, and the cold air in the output channel 222 can be distributed and output, so that the cold air of the output channel 222 is evenly output to the corresponding battery cluster 114, so that the cold air output from the output channel 222 is uniform, thereby improving the uniform cooling of the battery cluster 114.

[0061] In one embodiment, Figure 3 As shown, the flow dividing assembly 214 includes a plurality of flow dividing plates 216 , each of which is arranged at intervals in the input channel 210 ; a first end of each flow dividing plate 216 is arranged adjacent to the input port of the input channel 210 , and a second end of each flow dividing plate 216 is arranged away from the input port of the input channel 210 .

[0062] For example, the number of the splitter plates 216 may be determined according to the number of the output channels 222. For example, if the number of the output channels 222 is 2, the number of the splitter plates 216 is 1. For another example, if the number of the output channels 222 is 3, the number of the splitter plates 216 is 2.

[0063] For example, the input channel 210 can be divided into an input air slot and a cover body, and the input air slot and the cover body enclose the input channel 210. The flow divider assembly 214 includes a flow divider plate 216, one side of the flow divider plate 216 is attached to the bottom of the input air slot, and the other side of the flow divider plate 216 is attached to the cover body. By setting the first end of the flow divider plate 216 adjacent to the input port of the input channel 210 and the second end of the flow divider plate 216 away from the input port of the input channel 210, the input channel 210 is divided into two input sub-channels 212, and the input ports of the two input sub-channels 212 are respectively connected to the cold air output ends of the air conditioning device 112, the output port of one input sub-channel 212 is connected to the input port of one output channel 222, and the output port of the other input sub-channel 212 is connected to the input port of another output channel 222, so that the air guide structure 20 is divided into two cold air transmission channels, and then the cold air is distributed to the two cold air transmission channels for transmission, so as to achieve air cooling of the two battery clusters 114. It should be noted that the cold air distribution process when two or more diverter plates 216 are set in the input channel 210 is similar to the cold air distribution process when one diverter plate 216 is set in the above-mentioned input channel 210, and will not be repeated here.

[0064] In one embodiment, Figure 2 As shown, the diverter plate 216 includes a diverter plate 2162, a third guide plate 2164 and a fourth guide plate 2166; the first end of the diverter plate 2162 is arranged adjacent to the input port of the input channel 210, the second end of the diverter plate 2162 is respectively connected to the first end of the third guide plate 2164 and the first end of the fourth guide plate 2166, the first end of the third guide plate 2164 and the first end of the fourth guide plate 2166 are respectively arranged away from the input port of the input channel 210; the third guide plate 2164 and the fourth guide plate 2166 form a second preset angle between them.

[0065] The flow divider 2162, the third flow guide 2164 and the fourth flow guide 2166 are all plate-shaped structures. The flow divider 2162, the third flow guide 2164 and the fourth flow guide 2166 can be an integrally formed structure.

[0066] By setting the first end of the diverter 2162 adjacent to the input port of the input channel 210, the third guide plate 2164 and the fourth guide plate 2166 are set at a second preset angle, so that the diverter 2162 divides the input channel 210 into two input sub-channels 212, part of the cold air enters from one of the input sub-channels 212, and is guided by the third guide plate 2164 to be transmitted in the corresponding input sub-channel 212, and the cold air is transmitted to the corresponding output channel 222, part of the cold air enters from the other input sub-channel 212, and is guided by the fourth guide plate 2166 to be transmitted in the corresponding input sub-channel 212, and the cold air is transmitted to the corresponding output channel 222.

[0067] Since the input port and output port of the input subchannel are not in the same axial direction, for example, Figure 1 As shown, the axial direction of the input port of the input sub-channel is perpendicular to the axial direction of the output port. By setting the third guide vane 2164 and the fourth guide vane 2166, and the third guide vane 2164 and the fourth guide vane 2166 form a second preset angle, the third guide vane 2164 can reduce the resistance of the cold air flow, and guide the cold air to blow more smoothly to the output port of the corresponding input sub-channel. The second guide vane 2244 can reduce the resistance of the cold air flow, and guide the cold air to blow more smoothly to the output port of the corresponding output sub-channel, thereby improving the transmission efficiency of the cold air diversion of the input channel.

[0068] In one embodiment, Figure 3 As shown, the output port of the output channel 222 is provided with a first baffle 228 ; the first baffle 228 is used to guide the cold air to be transmitted to the corresponding battery cluster 114 .

[0069] The first baffle 228 and the output channel 222 may be an integrally formed structure. In another example, the first baffle 228 may be disposed at the output port of the output channel 222 by screwing, clamping or welding.

[0070] For example, the air guide structure can be arranged above the battery cluster 114, the output port of the output channel 222 is arranged adjacent to the first side wall of the battery compartment 110, and the first baffle 228 is parallel to the first side wall of the battery compartment 110. By setting the first baffle 228 at the output port of the output channel 222, the first baffle 228 can guide the cold air of the output channel 222 to be transmitted downward to the corresponding battery cluster 114, thereby cooling the corresponding battery cluster 114, and at the same time avoiding the cold air in the output channel 222 from blowing toward the first side wall of the battery compartment 110 and causing cold air loss, thereby improving the cooling efficiency of the battery cluster 114.

[0071] In one embodiment, Figure 3 and Figure 4As shown, the output port of the output channel 222 is also provided with a second baffle 232; the battery cluster 114 is provided with a cooling air inlet; the second baffle 232 and the first baffle 228 are enclosed to form a drainage channel 234; the drainage channel 234 is respectively connected to the output port of the output channel 222 and the cooling air inlet of the corresponding battery cluster 114.

[0072] The second baffle 232 and the output channel 222 may be an integrally formed structure. In another example, the second baffle 232 may be disposed at the output port of the output channel 222 by screwing, clamping or welding.

[0073] For example, the air guide structure can be arranged above the battery cluster 114, the output port of the output channel 222 is arranged adjacent to the first side wall of the battery compartment 110, the first baffle 228 is parallel to the first side wall of the battery compartment 110, the second baffle 232 is parallel to the first baffle 228, and the first baffle 228 and the second baffle 232 are arranged at intervals, and the first baffle 228 and the second baffle 232 are arranged at the output port of the output channel, so that the first baffle 228 and the second baffle 232 enclose a drainage channel 234, and the first end of the drainage channel 234 is connected and communicated with the output channel 222. The output port, the second end of the drainage channel 234 is connected to and communicated with the cooling air inlet of the corresponding battery cluster 114, so that the cold air of the output channel 222 can be transmitted to the drainage channel 234 through the output port, and then transmitted to the cooling air inlet of the corresponding battery cluster 114 after flowing through the drainage channel 234, so that the cold air is blown to the inside of the corresponding battery cluster through the cooling air inlet of the battery cluster 114, thereby cooling the corresponding battery cluster 114, and at the same time avoiding the loss of the cold air in the output channel 222 during the transmission to the battery cluster 114, further improving the cooling efficiency of the battery cluster 114.

[0074] In one embodiment, Figure 1 and Figure 3 As shown, the air guide structure 20 further includes a plurality of noise reduction plates 226 ; at least one noise reduction plate 226 is disposed on the inner side wall of each output channel 222 .

[0075] The noise reduction plate 226 and the output channel 222 may be an integrally formed structure, and the noise reduction plate 226 may also be arranged on the inner wall of the output channel 222 by welding, bonding, or screwing.

[0076] In one example, a plurality of noise reduction plates 226 are arranged at intervals on the inner wall of the output channel 222, and a preset angle is formed between the noise reduction plates 226 and the inner wall of the output channel 222. Therefore, when the output air duct transmits cold air, the noise generated by the transmission of cold air can be reduced based on the noise reduction effect of the noise reduction plates 226.

[0082] In the above embodiment, by optimizing and improving the air guide structure 20, a diversion component 214 is set in the input channel 210 to divide the input channel 210 into a plurality of input sub-channels 212, so that the cold air output by the air-conditioning equipment 112 can be transmitted to the corresponding output channel 222 through the input sub-channel 212; a diversion component 224 is set in the output channel 222 to guide the cold air in the output channel 222 and redistribute the output to the corresponding battery cluster 114, so that the cold air output by the output channel 222 can be evenly blown to the corresponding battery cluster 114, so that the cold air of the output channel 222 is evenly distributed, ensuring that the temperature rise and temperature difference of the system battery are within a reasonable range, thereby improving the system life.
