Description

[0002] In the related technology, the space of 7MWh container is limited, the number of cells is large, and the heat generation is large. According to calculations, a liquid cooling unit with a cooling capacity of more than 120kW is required to meet the heat dissipation demand. At present, the cooling capacity of a single refrigeration unit is about 60kW. If the heat dissipation demand of more than 120kW required by the 7MWh container is to be met, two refrigeration units are required, and the space in the container cannot meet the requirements.

Since the current liquid cooling unit is in the form of an integrated cabinet, the axial flow fan 221 is arranged on the top of the cabinet 211 (such as Figure 1 As shown), if the heat dissipation efficiency of the condenser needs to be increased, the number of axial flow fans 221 needs to be increased, which will cause the space occupied by the cabinet 211 to become larger, and the compartment where the cabinet 211 is located will no longer be able to accommodate the cabinet 211 with the axial flow fans 221 added.

[0048] In the related art, under the background of long-term energy storage, the power demand of energy storage containers is getting higher and higher, which brings with it the problem of battery heat dissipation and limited container space. The embodiment of the utility model can arrange a liquid cooling unit with a cooling capacity of more than 120kW in a 20-foot container through the split arrangement of the liquid cooling unit, meeting the heat dissipation demand of 7MWh container batteries.

[0049] Please also read Figure 2 , Figure 3 and Figure 5 Now, the energy storage container 100 provided by the embodiment of the utility model is described. The box body 10 is roughly in a rectangular shape, the first direction X is the length direction of the box body 10; the second direction Y is the height direction of the box body 10; and the third direction Z is the width direction of the box body 10.

[0050] The energy storage container 100 includes a box body 10, a liquid cooling unit and a battery assembly 30. The battery assembly 30 is accommodated in the box body 10, and the liquid cooling unit is at least partially accommodated in the box body 10. The liquid cooling unit is used to dissipate heat for the battery assembly 30 to ensure the normal operation of the battery assembly 30.

[0051] A battery compartment 120 and a liquid cooling compartment 110 are disposed in the box body 10 . The battery compartment 120 and the liquid cooling compartment 110 are arranged side by side in the box body 10 , such as the battery compartment 120 is located on one side, and the liquid cooling compartment 110 is located on the other side.

[0052] The liquid cooling unit includes a liquid cooling host assembly 21 and an air cooling assembly 22. The liquid cooling host assembly 21 is accommodated in the liquid cooling compartment 110 and is located on one side of the box body 10 along the first direction X; the air cooling assembly 22 is arranged on the top of the battery compartment 120, and the air cooling assembly 22 is connected to the liquid cooling host assembly 21 to realize a closed loop of the liquid cooling unit. In one embodiment, the air cooling assembly 22 is located directly above the battery assembly 30.

[0053] The energy storage container 100 provided in the embodiment of the utility model is compared with the related art. The energy storage container 100 in the embodiment of the utility model is configured by separately arranging the air cooling component 22 and the liquid cooling main unit component 21 of the liquid cooling unit, that is, the liquid cooling main unit component 21 is arranged in the liquid cooling bin 110, and the air cooling component 22 is arranged on the top of the battery bin 120 and is connected to the liquid cooling main unit component 21. Thus, the space in the energy storage container 100 can be fully utilized to meet the heat dissipation demand of the 7MWh energy storage container 100. At the same time, by separately arranging the air cooling component 22 and the liquid cooling main unit component 21, more fans can be arranged and the air circulation inside the energy storage container 100 is more conducive to the heat dissipation.

[0054] In one embodiment of the present invention, please refer to Figure 2 and Figure 3 , the air cooling component 22 includes an axial flow fan 221 and a condenser 222. Among them, the axial flow fan 221 is set to be multiple, and the multiple axial flow fans 221 are arranged side by side along the first direction X; the condenser 222 is set to be multiple, and the multiple condensers 222 are arranged corresponding to the multiple axial flow fans 221. In this embodiment, an air inlet end is opened on the side wall of the box body 10, and the gas enters through the air inlet end and is discharged by the axial flow fan 221 after flowing through the condenser 222. For example, the cold air becomes hot air after flowing through the condenser 222 and is discharged by the axial flow fan 221. The number of axial flow fans 221 and the number of condensers 222 can be selected according to actual needs, and the number of axial flow fans 221 can be equal to the number of condensers 222, and the number of axial flow fans 221 can also be an integer multiple of the number of condensers 222. In addition, the arrangement of the axial flow fans 221 can also be other ways, mainly to maximize the space utilization of the energy storage container 100.

[0055] In one embodiment, air inlet ends are opened on the side walls of the box body 10 on both sides along the first direction X. At this time, the air inlet on both sides makes the airflow in the energy storage container 100 more uniform, and also improves the heat dissipation efficiency of the condenser 222.

[0056] In another embodiment, the axial flow fans 221 and the condensers 222 are arranged in a one-to-one correspondence, that is, the number of the axial flow fans 221 is the same as the number of the condensers 222, and one axial flow fan 221 is arranged corresponding to one condenser 222. In this embodiment, the condenser 222 is arranged below the axial flow fan 221, so that air enters from both sides and is arranged from the top, which can improve the heat dissipation efficiency of the condenser 222.

[0057] In one embodiment of the present invention, please refer to Figure 3 , the axial flow fan 221 includes a shell, a fan blade and a motor. Among them, the fan blade is arranged in the shell; the motor is arranged in the shell, and the motor is used to drive the fan blade to rotate. The shell has an air inlet arranged near the condenser 222 and an air outlet arranged away from the condenser 222. The shell is sealed with the condenser 222 at the air inlet, and the shell is sealed with the box 10 at the air outlet, so that the air duct in the shell is sealed. It can be understood that if the shell and the condenser 222 or the box 10 are not sealed, then a part of the gas will directly flow into the gap between the shell and the condenser 222 or the gap between the shell and the box 10 and flow out from the air outlet, at this time, the heat dissipation efficiency of the axial flow fan 221 will be reduced. Therefore, in this embodiment, the shell and the condenser 222 are sealed, and the shell and the box 10 are sealed, which can improve the heat dissipation efficiency of the axial flow fan 221, and then improve the heat dissipation efficiency of the condenser 222, thereby improving the circulation conversion efficiency of the refrigerant.

[0059] In one embodiment of the present invention, please refer to Figures 2 to 4 The box body 10 includes a side plate 11, a bottom plate 12 and a top plate 13.

The plurality of side plates 11, the bottom plate 12 and the top plate 13 enclose a receiving space 101, and the receiving space 101 has a battery compartment 120 and a liquid cooling compartment 110.

[0060] In this embodiment, a plurality of through holes are provided on the top plate 13, and the air outlet of the housing of the axial flow fan 221 is connected to the through holes, thereby forming an air outlet end of the air passage, which is arranged upward. One end of the housing having the air outlet is sealed and connected to the top plate 13. In this embodiment, the space of the energy storage container 100 is fully utilized, and the airflow in the cabin of the energy storage container 100 is made more uniform.

[0061] In one embodiment of the present invention, please refer to Figure 4 , the air inlet end of the air cooling component 22 is set as a hollow structure 102 at one end of the side plate 11 close to the top plate 13 along the second direction Y. At this time, air is sucked from the hollow structure 102 and discharged upward from the top plate 13. In one embodiment, the hollow structure 102 is a grid structure set along the thickness direction of the side plate 11. It can be understood that in other embodiments, the hollow structure 102 can also be other forms of structures in the relevant technology.

[0062] In one embodiment of the present invention, please refer to Figure 2 and Figure 5 , the projection of the effective heat dissipation area of ​​the condenser 222 along the second direction Y is located in the opening area of ​​the air inlet of the axial flow fan 221. Among them, the effective heat dissipation area of ​​the condenser 222 is the area where the condenser 222 is provided with heat dissipation fins, and this area can effectively dissipate heat for the target medium.

[0063] In one embodiment of the present invention, please refer to Figure 3 The liquid cooling unit also includes a pipeline assembly 23, which is used to connect the liquid cooling host assembly 21 and the air cooling assembly 22, and the pipeline assembly 23 is accommodated in the accommodation space 101. Specifically, the liquid cooling host assembly 21 is provided with connection ports 210 at both ends along the third direction Z, and the pipeline assembly 23 includes an air inlet pipeline 231 and a liquid outlet pipeline 232. Among them, one end of the air inlet pipeline 231 is connected to one of the connection ports 210 of the liquid cooling host assembly 21, and the other end of the air inlet pipeline 231 is connected to the condenser 222; one end of the liquid outlet pipeline 232 is connected to another connection port 210 of the liquid cooling host assembly 21, and the other end of the liquid outlet pipeline 232 is connected to the condenser 222.

The two connecting ports 210 are respectively arranged at the two ends of the liquid-cooled host assembly 21 along the third direction Z, which can save the pipeline length of the pipeline assembly 23 and facilitate the arrangement of the pipeline assembly 23 in the energy storage container 100.

[0064] In one embodiment, see Figure 3The air inlet pipeline 231 includes a main air inlet pipeline 2311 and a plurality of branch air inlet pipelines 2312, and the liquid outlet pipeline 232 includes a main liquid outlet pipeline 2321 and a plurality of branch liquid outlet pipelines 2322; wherein the plurality of branch air inlet pipelines 2312 are used to connect the plurality of condensers 222 with the main air inlet pipeline 2311, and the plurality of branch liquid outlet pipelines 2322 are used to connect the plurality of condensers 222 with the main liquid outlet pipeline 2321. In this embodiment, such a configuration can save the total length of the pipeline and make the structure in the energy storage container 100 more compact.

[0065] In one embodiment of the present invention, please refer to Figure 5 The battery assembly 30 includes a battery module and a liquid cooling plate, and the liquid cooling plate is used to perform heat exchange for the battery module. The liquid cooling host assembly 21 includes a cabinet 211, and a heat exchanger 212, a power component 213, a compressor 214 and a throttle 215 arranged in the cabinet 211. The above-mentioned connection port 210 is arranged at both ends of the cabinet 211 along the third direction Z. Among them, the heat exchanger 212, the liquid cooling plate and the power component 213 are connected in sequence through pipelines to form a primary closed loop, and the primary closed loop is used to dissipate heat from the battery module; the heat exchanger 212, the compressor 214, the condenser 222 and the throttle 215 are connected in sequence through pipelines to form a secondary closed loop, and the secondary closed loop is used to improve the circulation conversion efficiency of the refrigerant, thereby improving the heat dissipation efficiency of the heat exchanger 212 to the battery module.

[0066] In a specific implementation, the heat exchanger 212 is used for heat exchange, and it can be a plate heat exchanger; the power part 213 is used to transport the coolant, and it can be a water pump; the compression part 214 is used to compress the low-temperature and low-pressure gaseous refrigerant into a high-temperature and high-pressure gaseous state, and it can be an electric compressor; the throttling part 215 is used to throttle the refrigerant, and it can be an expansion valve. It can be understood that the plate heat exchanger, the water pump, the electric compressor and the expansion valve can adopt the corresponding structures in the relevant technology, and will not be described in detail here.

[0067] The working principle of the liquid cooling unit of this embodiment is: the temperature of the high-temperature coolant is reduced by evaporating the refrigerant in the heat exchange element 212 and absorbing heat, and then the low-temperature coolant is transported to each liquid cooling plate through the power element 213, and the high-temperature coolant flowing out of the liquid cooling plate flows back to the heat exchange element 212 through the power element 213, and circulates in this way to realize a primary closed loop; the compression element 214 first compresses the low-temperature and low-pressure gaseous refrigerant into a high-temperature and high-pressure gaseous state, and transports it to the condenser 222 (dissipating heat through the axial flow fan 221), the refrigerant is cooled to a liquid state, and then throttled by a throttling element 215. At this time, most of the refrigerant is still in a liquid state, which is a medium-temperature and high-pressure liquid refrigerant, and then flows to the heat exchange element 212, where the liquid refrigerant is evaporated and absorbs heat, reducing the temperature of the coolant, and then the refrigerant becomes a gas and returns to the compression element 214, thus forming a refrigeration cycle, that is, realizing a secondary closed loop.

[0068] In one embodiment of the present invention, please refer to Figure 5 , a liquid inlet temperature sensor 216 is provided on the pipeline between the heat exchanger 212 and the liquid cooling plate; and a liquid outlet temperature sensor 217 is provided on the pipeline between the liquid cooling plate and the power component 213. In this embodiment, the operating parameters of the power component 213 can be controlled by the temperature difference of the two temperature parameters, the liquid inlet temperature sensor 216 and the liquid outlet temperature sensor 217, which are fed back in real time. In other embodiments, the liquid inlet temperature sensor 216 can be provided only on the pipeline between the heat exchanger 212 and the liquid cooling plate, or the liquid outlet temperature sensor 217 can be provided only on the pipeline between the liquid cooling plate and the power component 213.
