[0019] In addition, since the temperature range required by electrical devices such as uninterruptible power supplies during operation is above 0°C, the water temperature of the coolant provided by the liquid cooling unit is usually above 18°C±0.5°C.

[0042] One or more embodiments of the present application disclose an energy storage container. Figure 1 and Figure 2 The energy storage container includes a box body 1, an electrical device 2, a dehumidification device 3 and a liquid cooling unit 4. The box body 1 includes a confluence bin 11, and the electrical device 2 and the dehumidification device 3 are arranged in the confluence bin 11; the dehumidification device 3 includes a shell 31, a gas flow device 32 and a dehumidifier 33, the shell 31 has an air inlet 311 and an air outlet 312, the air inlet 311 is connected with the air outlet 312 to form an air duct, the dehumidifier 33 is arranged in the shell 31, the liquid cooling unit 4 is connected with the dehumidifier 33, the liquid cooling unit 4 is used to output the coolant to circulate in the dehumidifier 33, and the gas flow device 32 is arranged in the air duct so that the airflow flows through the dehumidifier 33.

[0043] The confluence chamber 11 of the housing 1 provides installation space for the dehumidification device 3 and the electrical device 2; for example, Figure 1 and Figure 2 In the embodiment, the dehumidification device 3 and the electrical device 2 can be installed in the confluence chamber 11 in an alternate arrangement. In other words, a certain heat dissipation interval is maintained between the two, thereby facilitating the normal heat dissipation operation of the electrical device 2.

[0044] The gas flow device 32 can be installed at any position of the air duct, for example, it can be installed at a certain position inside the housing 31, or it can be installed at the position of the air outlet 312 of the housing 31 (see Figure 3 The gas flow device 32 may be an exhaust fan, a blower or an air negative pressure device. As long as the gas flow device 32 can draw the air in the confluence bin into the housing and flow the air back from the housing to the confluence bin, it is applicable to the present technical solution and is not specifically limited here.

[0045] Since the water temperature of the coolant provided by the liquid cooling unit 4 is usually within the range of 18°C ​​± 0.5, when the coolant provided by the liquid cooling unit 4 circulates inside the dehumidifier 33, the dehumidifier 33 itself can generate a certain amount of heat. When the humidity in the confluence bin 11 is relatively high, the gas flow device 32 arranged in the air duct of the outer shell 31 works to generate a negative pressure inside the outer shell 31 of the dehumidifier 3, thereby sucking the air with relatively high humidity in the confluence bin 11 and entering the inner part of the outer shell 31 through the air inlet 311 of the outer shell 31, and then the air with relatively high humidity is heated by the dehumidifier 33. At this time, the heat on the surface of the dehumidifier 33 heats, dries and dehumidifies the air with relatively high humidity entering the outer shell 31, and the dried air returns to the confluence bin 11 from the air outlet 312 of the outer shell 31, thereby effectively reducing the humidity in the confluence bin 11 through the cooperation of the dehumidifier 3 and the liquid cooling unit 4, thereby providing a dry working environment for the electrical device 2 to avoid the high humidity in the confluence bin 11 reducing the electrical safety clearance of the various components of the electrical device 2.

[0046] In addition, since the temperature range required by the electrical device 2, such as the uninterruptible power supply 22, during operation is above 0°C, and the water temperature of the coolant provided by the liquid cooling unit 4 is usually above 18°C±0.5°C, the heat on the surface of the dehumidifier 33 heats the air entering the outer shell 31 to form warm air with a certain temperature, such as about 18°C. The warm air returns to the confluence bin 11 from the air outlet of the outer shell 31 to keep the temperature in the confluence bin 11 within the range of 0°C to 18°C, thereby ensuring the safe and normal operation of the entire electrical device within the temperature range of 0°C to 18°C ​​through the cooperation of the dehumidification device 3 and the liquid cooling unit 4.

[0047] Fig. 9 This is a schematic diagram of the piping structure of the liquid cooling unit 4 in some embodiments of the present application.

[0048] In some embodiments, the dehumidifier 33 includes a dehumidification pipeline 331, the liquid cooling unit 4 includes a liquid-cooled air conditioner 40, a first liquid outlet pipe 41 and a first liquid return pipe 42, the dehumidification pipeline 331 has a liquid inlet pipe 3311 and a liquid outlet pipe 3312, the liquid outlet end of the liquid-cooled air conditioner 40 is connected to the liquid inlet pipe 3311 through the first liquid outlet pipe 41, and the liquid outlet pipe 3312 is connected to the liquid return end of the liquid-cooled air conditioner 40 through the first liquid return pipe 42.

[0049] In at least one embodiment, the liquid-cooled air conditioner 40 can be connected to the dehumidification pipeline 331 through the first liquid outlet pipe 41 and the first liquid return pipe 42. Specifically, the two ends of the first liquid outlet pipe 41 are respectively connected to the liquid outlet end of the liquid-cooled air conditioner 40 and the liquid inlet pipe 3311 of the dehumidification pipeline 331, and the two ends of the first liquid return pipe 42 are respectively connected to the liquid outlet pipe 3312 of the dehumidification pipeline 331 and the liquid return end of the liquid-cooled air conditioner 40; when the dehumidification device 3 is working, the liquid outlet end of the liquid-cooled air conditioner 40 outputs the coolant, which enters the dehumidification pipeline 331 from the liquid inlet pipe 3311 through the first liquid outlet pipe 41. 31, and circulates, and then flows back to the inside of the liquid-cooled air conditioner 40 through the liquid outlet pipe 3312 and the first return liquid pipe 42. Since there is flowing coolant inside the dehumidification pipeline 331, when the fan 32 is working, the air in the confluence bin 11 can be sucked into the outer shell 31, and pass through the surface of the dehumidification pipeline 331 to heat, dry and dehumidify the air with high humidity in the outer shell 31 through the dehumidification pipeline 331, and then discharged from the air outlet 312 of the outer shell 31 to the confluence bin 11, thereby realizing the drying and dehumidification operation of the air in the confluence bin 11.

[0050] Specifically, the liquid inlet 3311 and the liquid outlet 3312 of the dehumidification pipeline 331 can be connected to the first liquid outlet pipe 41 and the first liquid return pipe 42 through a pipe joint.

[0051] In addition, the bending shape of the dehumidification pipeline 331 can be serpentine, rectangular, ring-shaped, U-shaped, spiral, etc., which is not specifically limited here.

[0052] In some embodiments, in combination Figure 5 As shown, the dehumidifier 33 also includes a receiving box 332, which is a shell structure with two openings and a hollow interior, and the dehumidification pipeline 331 is installed in the receiving box 332; the receiving box 332 is arranged in the outer shell 31, and the two openings of the receiving box 332 are respectively connected to the air inlet 311 and the air outlet 312 of the outer shell 31.

[0053] In at least one embodiment, since the storage box 332 is a shell structure, the dehumidification pipeline 331 is installed inside the storage box 332; and the two openings of the storage box 332 are respectively connected to the air inlet 311 and the air outlet 312 of the shell 31, so that when the fan 32 is working, a negative pressure is generated inside the shell 31, so that the air in the confluence bin 11 enters the inside of the shell 31 through the air inlet 311 of the shell 31, and then enters the storage box 332 from an opening of the storage box 332. At this time, the storage box 332 The coolant circulating inside the dehumidification pipeline 331 can not only heat and dehumidify the air inside the receiving box 332, but also because the volume of the receiving box 332 is smaller than the volume of the outer shell 31, it can reduce the circulation channel area of ​​the heated and dehumidified air, thereby increasing the flow rate of the heated and dehumidified air in the receiving box 332. Subsequently, the accelerated dry air flows out from another opening of the receiving box 332, and is discharged into the confluence bin 11 through the fan 32 and the air outlet 312 of the outer shell 31, so as to improve the dehumidification efficiency of the entire confluence bin 11.

[0054] In some embodiments, in combination Figure 3 and Figure 4 As shown, the dehumidification device 3 further includes a drain pipe 34 , and the drain pipe 34 is arranged at the bottom of the shell 31 .

[0055] In at least one embodiment, one end of the drain pipe 34 is connected to the outer shell 31, and the other end can extend to the outside of the confluence bin 11; when the fan 32 of the dehumidification device 3 is working, the air with higher humidity in the confluence bin 11 can be sucked into the interior of the outer shell 31, some air can be heated and dehumidified by the dehumidifier 33, and a small amount of humid air will form condensed water on the inner wall of the outer shell 31. At this time, the condensed water can be discharged to the outside of the confluence bin 11 through the drain pipe 34, thereby preventing the condensed water from accumulating in the outer shell 31 of the dehumidification device 3.

[0056] In some embodiments, in combination Figure 1 and Figure 2 As shown, the box body 1 also includes an air-conditioning compartment, which is arranged above the confluence compartment 11, and the liquid-cooled air conditioner 40 is installed in the confluence compartment 11; the air outlet 312 of the dehumidification device 3 is arranged opposite to the electrical device 2.

[0057] In at least one embodiment, the air conditioning compartment is arranged above the confluence compartment 11 to fully utilize the vertical space of the box body 1; the liquid-cooled air conditioner 40 is installed in the confluence compartment 11, and the electrical device 2 is installed in the confluence compartment 11, so that the liquid-cooled air conditioner 40 is above the electrical device 2. Since the air outlet 312 of the dehumidification device 3 is arranged relative to the electrical device 2, the dry air coming out of the air outlet 312 of the dehumidification device 3 is blown toward the electrical device 2, which can not only dry and dehumidify the confluence compartment 11 where the electrical device 2 is located, but also accelerate the diffusion of heat on the surface of the electrical device 2, and also play a role in dissipating heat from the electrical device 2. Among them, the confluence compartment 11 is arranged above the confluence compartment 11. Figure 2 The positive direction of the Z-axis of the coordinate system is above the confluence bin 11 .

[0058] Figure 6 This is a schematic diagram of the structure of an energy storage container in some embodiments of the present application. Figure 7 for Figure 6 Schematic diagram of the enlarged structure at point C in the middle.

[0059] In at least one embodiment, the electrical device 2 includes a distribution box 21, an uninterruptible power supply 22, a transformer 23 and a combiner cabinet 24, wherein the combiner cabinet 24 can be arranged below the air outlet 312 of the dehumidification device 3, and the distribution box 21 can be arranged on one side of the combiner cabinet 24, such as the rear side (see Figure 2 As shown), the transformer 23 can be installed on one side of the distribution box 21, such as the rear side, and the uninterruptible power supply 22 can be installed below the transformer 23 (see Figure 7 As shown), the space of the confluence bin is fully utilized.

[0063] If the energy storage battery includes a battery cluster 5 , the liquid outlet and liquid return end of the liquid cooling air conditioner 40 are connected to the second liquid outlet pipe 43 and the second liquid return pipe 44 respectively.

[0064] The liquid inlet and liquid outlet of each liquid cooling plate 6 are connected to the third liquid outlet pipe 451 and the third liquid return pipe 452 respectively, wherein the liquid inlet of each liquid cooling plate 6 is connected to the second liquid outlet pipe 43 through the third liquid outlet pipe 451 respectively, and the liquid outlet of each liquid cooling plate 6 is connected to the second liquid return pipe 44 through the third liquid return pipe 452 respectively, so that the liquid cooling air conditioner 40 transports the cooling liquid to the liquid cooling plate 6 through the second liquid outlet pipe 43 and the corresponding third liquid outlet pipe 451, and circulates inside the liquid cooling plate 6. Since the liquid cooling plate 6 is in contact with and connected to the battery pack 51, it can absorb the heat generated during the operation of the battery pack 51, and then the cooling liquid flows back to the liquid cooling air conditioner 40 from the liquid outlet of the liquid cooling plate 6 through the third liquid return pipe 452 and the second liquid return pipe 44, so as to complete the cooling operation of each battery pack 51 in the entire battery cluster 5.

[0066] In some embodiments, in combination Figure 6 and Fig. 9 As shown, the number of the battery clusters 5 is multiple, and the multiple battery clusters 5 are arranged at intervals, the liquid cooling unit 4 also includes a fourth liquid outlet pipe 46 and a fourth liquid return pipe 47, the liquid outlet end of the liquid-cooled air conditioner 40 is connected to at least part of the second liquid outlet pipe 43 through the fourth liquid outlet pipe 46; at least part of the second liquid return pipe 44 is respectively connected to the fourth liquid return pipe 47, and the fourth liquid return pipe 47 is connected to the liquid return end of the liquid-cooled air conditioner 40.

[0067] In at least one embodiment, the energy storage battery may include a plurality of battery clusters 5, and the plurality of battery clusters 5 may be arranged along the length direction of the entire box body 1. Figure 6 As shown, multiple battery clusters 5 (six) can be connected along Figure 6 The X-axis arrangement setting of the coordinate system.

[0068] The fourth liquid outlet pipe 46 and the fourth liquid return pipe 47 can be used as a circulation channel for providing cooling liquid to the liquid cooling structure corresponding to all battery clusters 5, and the second liquid outlet pipe 43 and the second liquid return pipe 44 can be used as a circulation channel for providing cooling liquid to the liquid cooling structure corresponding to each battery cluster 5, and the third liquid outlet pipe 451 and the third liquid return pipe 452 can be used as a circulation channel for providing cooling liquid to the liquid cooling plate 6 corresponding to a single battery pack 51 in the battery cluster 5, so the number of the second liquid outlet pipe 43 and the second liquid return pipe 44 matches the number of battery clusters 5, and the number of the third liquid outlet pipe 451 and the third liquid return pipe 452 can match the number of battery packs 51 and liquid cooling plates 6. Among them, if the energy storage battery includes more than two battery clusters 5, the liquid outlet end and the liquid return end of the liquid cooling air conditioner 40 are connected to the fourth liquid outlet pipe 46 and the fourth liquid return pipe 47 respectively. Among them, at least part of it means that it can be part of the number of second liquid outlet pipes, or it can be all of the second liquid outlet pipes, which can be flexibly arranged according to the scene.

[0069] To Figure 6 Taking the cooling of a battery cluster 5 in the battery cluster as an example, the liquid outlet end of the liquid-cooled air conditioner 40 outputs coolant, which enters the interior of the liquid cooling plate 6 from the liquid inlet of the liquid cooling plate 6 through the fourth liquid outlet pipe 46, the second liquid outlet pipe 43 and the third liquid outlet pipe 451 in sequence, and circulates inside the liquid cooling plate 6. Since the liquid cooling plate 6 is in contact and connected with the battery pack 51, it can absorb the heat generated during the operation of the battery pack 51, and then flows back to the liquid cooling air conditioner 40 from the liquid outlet of the liquid cooling plate 6 through the third liquid return pipe 452, the second liquid return pipe 44 and the fourth liquid return pipe 47 to complete the cooling operation of each battery pack 51 in the battery cluster 5.

[0072] In at least one embodiment, since the liquid inlet and liquid outlet of the liquid cooling plate 6 are respectively connected to the third liquid outlet pipe 451 and the third liquid return pipe 452, when the faulty battery pack 51 needs to be disassembled and repaired, the two-way stop valve 48 installed between the third liquid outlet pipe 451 and the liquid inlet of the liquid cooling plate 6, and the two-way stop valve 48 installed between the liquid outlet of the liquid cooling plate 6 and the third liquid return pipe 452 can be disconnected, so that the pipeline from the second liquid outlet pipe 43 to the liquid inlet of the liquid cooling plate 6 through the third liquid outlet pipe 451 is disconnected, and the pipeline from the liquid return port of the liquid cooling plate 6 to the second return pipe 44 through the third liquid return pipe 452 is disconnected, which can effectively prevent the liquid in the third liquid outlet pipe 451 and the third liquid return pipe 452 from leaking, so as to improve the safety and convenience of repairing the battery pack 51.

[0073] Specifically, the two-way stop valve 48 is used to prevent leakage of the installed pipeline, and a two-way stop valve in the prior art can be used, so its specific structure is not limited.

[0075] In at least one embodiment, when the portion of the fourth liquid outlet pipe 46 close to the liquid outlet end of the liquid-cooled air conditioner 40 and the portion of the fourth liquid return pipe 47 close to the liquid return end of the liquid-cooled air conditioner 40 are respectively assembled and connected with the liquid-cooled air conditioner 40, the length, inclination, etc. of the bellows 49 can be adjusted to facilitate the connection between the liquid outlet end and the liquid return end of the liquid-cooled air conditioner 40 and the fourth liquid outlet pipe 46 and the fourth liquid return pipe 47 respectively, so as to avoid the fourth liquid outlet pipe 46 and the fourth liquid return pipe 47 being unable to be smoothly connected to the liquid-cooled air conditioner 40 due to early processing errors.

[0076] Specifically, the bellows 49 refers to a tubular elastic sensitive element formed by connecting foldable corrugated sheets along the folding and stretching direction. The bellows of the prior art can be used and will not be described in detail here.

[0077] In some embodiments, the battery compartment 12 includes a bottom plate and a drainage groove, the drainage groove is disposed on the bottom plate, and the drainage groove is disposed at an angle to the bottom plate.

[0078] In at least one embodiment, a drainage groove is provided on the bottom plate of the battery compartment 12, and the drainage groove has a certain inclination angle relative to the bottom plate of the confluence compartment 11, so that when there is condensed water inside the battery compartment 12, or coolant leaks from the pipes of the liquid cooling unit 4, the accumulated water on the bottom plate of the battery compartment 12 can be discharged through the drainage groove.

[0079] Specifically, one end of the drainage groove may be connected to the drainage ditch of the energy storage container installation area, or one end of the drainage groove may extend to the outside of the box body 1 to drain the accumulated water in the battery compartment 12.
