[0038] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention.

[0039] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.

[0040] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0041] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0042] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0043] The heat dissipation energy storage container 100 according to the embodiment of the utility model is described in detail below with reference to the accompanying drawings.

[0044] like Figures 1 to 10 As shown, the heat dissipation energy storage container 100 according to the embodiment of the utility model includes: an energy storage cabinet 10, a plurality of battery modules 20, a control device 30 and an air cooling device.

[0045] Specifically, the energy storage cabinet 10 includes a storage compartment group 12 and an electrical compartment 13. The storage compartment group 12 includes a plurality of storage compartments 121 arranged along a first direction. The electrical compartment 13 is located at one end of the storage compartment group 12 in the first direction. The electrical compartment 13 is provided with air inlets 134 on both sides adjacent to the storage compartment group 12, and a first air outlet 135 is provided on the side of the electrical compartment 13 away from the storage compartment group 12. A plurality of battery modules 20 are arranged in the plurality of storage compartments 121. The control device 30 is arranged in the electrical compartment 13 and is electrically connected to the plurality of battery modules 20. An air cooling device is arranged in the electrical compartment 13 to guide the gas entering from the air inlet 134 to the first air outlet 135.

[0046] In other words, the heat dissipation energy storage container 100 according to the embodiment of the utility model is mainly composed of an energy storage cabinet 10, a plurality of battery modules 20, a control device 30 and an air cooling device.

[0047] As a large-scale equipment, the energy storage cabinet 10 is usually placed vertically. For the convenience of explanation, the first direction and the second direction can be defined as mutually perpendicular horizontal directions, and the third direction is a vertical direction. Therefore, the third direction is equivalent to the height direction of the energy storage cabinet 10.

[0048] The storage compartment group 12 can be composed of a plurality of storage compartment groups 12. Figures 1 to 3 As shown, the multiple placement compartments 121 can be arranged in a straight line, and the arrangement direction of the multiple placement compartments 121 is a first direction. Therefore, in the first direction, at least one side surface of each placement compartment 121 will face other placement compartments 121, and in a second direction perpendicular to the first direction, the two side surfaces of each placement compartment 121 will not be blocked by other placement compartments 121.

[0049] In the first direction, the placement compartment group 12 has two ends, and one end of the placement compartment group 12 may be provided with an electrical compartment 13. The electrical compartment 13 may contain a control device 30, which may be used to control the battery module 20 in the placement compartment 121, and may also be used as a control structure of the heat dissipation energy storage container 100 to control the heat dissipation energy storage container 100. The control device 30 releases heat during operation.

[0050] It can be defined that the two side surfaces of the electrical compartment 13 in the second direction can be the front and back surfaces of the electrical compartment 13, and the two side surfaces of the placement compartment group 12 in the second direction can be the front and back surfaces of the placement compartment group 12. The front surface of the electrical compartment 13 can be adjacent to the front surface of the placement compartment group 12, and the back surface of the electrical compartment 13 can be adjacent to the back surface of the placement compartment group 12. The front and back surfaces of the electrical compartment 13 can be provided with air inlets 134, respectively, and a side surface of the electrical compartment 13 away from the placement compartment group 12 can be provided with a first air outlet 135. The air inlet 134 and the first air outlet 135 can be communicated with the interior of the electrical compartment 13, respectively.

[0051] The air cooling device may be disposed in the electrical compartment 13, and is used to guide the airflow to flow into the electrical compartment 13 from the air inlet 134, and guide the airflow in the electrical compartment 13 to be discharged from the first air outlet 135. In other words, the external cold air may flow into the electrical compartment 13 from the side of the electrical compartment 13 adjacent to the storage compartment group 12, and then be discharged outward from the side of the electrical compartment 13 away from the storage compartment group 12, so that the exhaust direction of the electrical compartment 13 is opposite to that of the storage compartment group 12, thereby preventing the hot air exhausted from the electrical compartment 13 from having a thermal effect on the battery module 20 in the storage compartment group 12.

[0052] Therefore, according to the heat dissipation energy storage container 100 of the embodiment of the utility model, the electrical compartment 13 of the energy storage cabinet 10 is arranged at one end of the placement compartment group 12 in the first direction, so that the battery module 20 can be separated from the control device 30 in the electrical compartment 13 to avoid mutual influence between the two. An air inlet 134 is arranged on the side adjacent to the placement compartment group 12 of the electrical compartment 13, and a first air outlet 135 is arranged on the side of the electrical compartment 13 away from the placement compartment group 12. The air cooling device can guide the cold air to flow in from the air inlet 134, and the hot air can be discharged outward from the side of the electrical compartment 13 away from the placement compartment group 12. The electrical compartment 13 is cooled by air cooling, which can not only reduce the cost of the heat dissipation energy storage container 100, but also avoid the heat generated by the electrical compartment 13 from causing thermal effects on the battery module 20 in the placement compartment 121, thereby preventing the battery module 20 from thermal runaway. The provision of multiple air inlets 134 can improve the heat dissipation efficiency, make the heat dissipation more uniform, and avoid the accumulation of high temperature in the electrical compartment 13.

[0053] In some specific embodiments, the energy storage cabinet 10 may include a cabinet body, a first partition 15, and a second partition 16. The first partition 15 may separate the interior of the cabinet body into a plurality of storage compartments 121. The storage compartments 121 may be provided with a receiving cavity 122, which may be used to receive the battery module 20.

[0054] In some optional embodiments, the volume of the electrical compartment 13 is smaller than the volume of the storage compartment 121 , and the electrical compartment 13 can be cooled by natural air cooling.

[0055] Optionally, the front and back sides of the electrical compartment 13 may be provided with grilles to form air inlets 134 .

[0056] According to one embodiment of the utility model, the air cooling device includes an air guide plate 41, which extends along an arc. In the arc extension direction of the air guide plate 41, the first end of the air guide plate 41 extends toward the air inlet 134, and the second end of the air guide plate 41 extends toward the first air outlet 135.

[0057] Specifically, the electrical compartment 13 may be provided with an air deflector 41, which may be an arc-shaped plate, and the cross section obtained by cutting the arc-shaped plate with a horizontal plane may be arc-shaped. In the direction of the arc line of the air deflector 41, the air deflector 41 may have two ends, namely a first end and a second end of the air deflector 41, the first end of the air deflector 41 may extend toward the air inlet 134, and the second end of the air deflector 41 may extend toward the first air outlet 135.

[0058] There may be an angle between the extension direction of the first end of the air guide plate 41 and the extension direction of the second end. Since the air guide plate 41 extends along an arc, an arc surface may be formed between the first end and the second end of the air guide plate 41, and the arc surface may guide the airflow entering from the air inlet 134 to flow toward the first air outlet 135.

[0059] In this embodiment, the wind guide plate 41 is a purely mechanical structure, which can guide natural wind to dissipate heat to the electrical compartment 13 without power drive, and can also cooperate with an additional blowing structure to dissipate heat to the electrical compartment 13. It has the advantages of simple structure, low cost and small space occupation.

[0060] According to some other embodiments of the utility model, an air guide channel 131 is provided in the electrical compartment 13, and the air guide channel 131 includes a first channel 132 and a second channel 133, the first channel 132 extends along the second direction, the second channel 133 extends along the first direction, and the first direction is perpendicular to the second direction. The two ends of the first channel 132 are respectively connected to the two air inlets 134, one end of the second channel 133 is connected to the first channel 132, and the other end of the second channel 133 is connected to the first air outlet 135, and the air guide plate 41 and the control device 30 are respectively arranged in the first channel 132.

[0061] Specifically, the wind guide channel 131 can be mainly connected by a first channel 132 and a second channel 133. The first channel 132 can extend substantially along the second direction and connect the two air inlets 134, and the second channel 133 can extend substantially along the first direction and connect the first channel 132 and the first air outlet 135.

[0062] A control device 30 and an air guide plate 41 may be provided in the first channel 132. The cold air entering from the air inlet 134 may first pass through the control device 30 to absorb the heat emitted by the control device 30. Then the heat conduction plate may guide the hot air to the second channel 133, so that the hot air flows to the first air outlet 135 through the second channel 133.

[0063] Therefore, the air guide channel 131 of this embodiment utilizes the first channel 132 to connect the two air inlets 134, so that cold air can flow in from both ends of the first channel 132 and be discharged through the shared second channel 133. The structural arrangement of the air guide channel 131 is reasonable, which is conducive to saving space and improving exhaust efficiency.

[0064] According to some optional embodiments of the present invention, there are two air guide plates 41, and the two air guide plates 41 are respectively a first air guide plate and a second air guide plate. In the arc extension direction of the air guide plate 41, one of the first end of the first air guide plate and the first end of the second air guide plate extends in the positive direction of the second direction, and the other extends in the reverse direction of the second direction, and the second end of the first air guide plate and the second end of the second air guide plate extend toward the first channel 132 respectively along the second direction.

[0065] Specifically, two air guide plates 41 may be provided in the first channel 132. For the sake of convenience, the two air guide plates 41 may be defined as a first air guide plate and a second air guide plate, respectively. The direction from the back of the electrical compartment 13 toward the front is the positive direction of the second direction, and the direction from the back of the electrical compartment 13 toward the front is the reverse direction of the second direction.

[0066] like Fig. 9 and Fig.10 As shown, in the arc extension direction of the first air guide plate, the first end of the first air guide plate can extend in the positive direction of the second direction, and the second end of the first air guide plate can extend in the first direction toward a side away from the placement compartment group 12. Thus, the first air guide plate can guide the airflow entering from the front of the electrical compartment 13 into the second channel 133.

[0067] In the arc extension direction of the second air guide plate, the first end of the second air guide plate can extend in the opposite direction of the second direction, and the second end of the second air guide plate can extend along the first direction toward a side away from the placement compartment group 12. Thus, the first air guide plate can guide the airflow entering from the back of the electrical compartment 13 into the second channel 133.

[0068] Therefore, the two air guide plates 41 of the present embodiment cooperate to guide the airflow entering through the two air inlets 134 of the electrical compartment 13 to flow out of the electrical compartment 13 through a common second channel 133 , which is beneficial to improving heat dissipation efficiency.

[0069] According to some other embodiments of the present invention, the first end of the first air guide plate and the first end of the second air guide plate are connected to the inner wall surface of the first channel 132 away from the second channel 133, and the second end of the first air guide plate is connected to the second end of the second air guide plate.

[0070] Thus, the two air guide plates 41 can be respectively connected to the inner wall surface of the first channel 132 and away from the second channel 133, so that the two air guide plates 41 can be separated from the second channel 133 to form a guide space, which is more conducive to guiding the airflow into the second channel 133.

[0071] In addition, the second ends of the two guide plates are connected, so that the two guide plates can be close to each other, reducing the space occupied by the two guide plates and making the structure of the air cooling device compact.

[0072] Optionally, the curvature of the air guide plate 41 may be 90°.

[0073] According to some optional embodiments of the present invention, the control device 30 includes two DC / DC components 31 (DC-DC converter is referred to as DC / DC for short), the two DC / DC components 31 are spaced apart along the second direction, and the air guide plate 41 is located between the two DC / DC components 31.

[0074] Specifically, in the second direction, the two DC / DC components 31 can be spaced apart, one of the two DC / DC components 31 is close to the air inlet 134 on the front side of the electrical compartment 13, and the other of the two DC / DC components 31 is close to the air inlet 134 on the back side of the electrical compartment 13, and the cold air entering from the two air inlets 134 can cool the two DC / DC components 31 respectively.

[0075] The air guide plate 41 is arranged between the two DC / DC components 31. The air guide plate 41 can be used to guide the heat-absorbed gas into the second channel 133 to avoid the accumulation of high-temperature gas in the first channel 132. The arrangement of the air guide plate 41 is more reasonable, which is conducive to improving the heat dissipation efficiency.

[0076] The DC / DC component 31 may be electrically connected to the battery module 20 in the storage compartment 121 , and a DC conversion circuit may be provided in the DC / DC component 31 .

[0077] According to some other embodiments of the present invention, the air cooling device further includes a first fan 42 , and the first fan 42 is disposed at the first air outlet 135 and / or the air inlet 134 .

[0078] Specifically, the first fan 42 may be disposed at the first air outlet 135 , or a fan may be disposed at the air inlet 134 , or fans may be disposed at the first air outlet 135 and the air inlet 134 respectively, which is not limited here.

[0079] The first fan 42 can be used to drive the gas in the electrical compartment 13 to flow more quickly, thereby improving the heat dissipation efficiency.

[0080] Optionally, there may be multiple first fans 42 to further improve heat dissipation efficiency.

[0081] For example, the first fan 42 includes an intake fan and an exhaust fan. The two air inlets 134 may be provided with an intake fan respectively, and the first air outlet 135 may be provided with an exhaust fan. Figure 4 As shown, two first air outlets 135 may be provided at a side of the electrical compartment 13 away from the compartment group 12 , and an exhaust fan may be provided at each first air outlet 135 .

[0082] According to some optional embodiments of the utility model, a heat insulating member is provided between the placement compartment group 12 and the electrical compartment 13, so that the heat insulating member can isolate the placement compartment group 12 and the electrical compartment 13, so that the placement compartment group 12 and the electrical compartment 13 do not interfere with each other, avoiding the heat generated by the two from affecting each other, which is beneficial to reducing the generation of condensed water and ensuring that the control device 30 in the electrical compartment 13 and the battery module 20 in the placement compartment group 12 respectively operate safely and stably.

[0083] Optionally, the second partition 16 may be formed as a heat insulating member, that is, the second partition 16 may be a heat insulating plate to prevent the placement compartment group 12 and the electrical compartment 13 from conducting heat.

[0084] In some specific implementations of the present invention, a first installation cavity 138 , a second installation cavity 139 and a third installation cavity 140 are further provided in the electrical compartment 13 .

[0085] In the first direction, the first installation cavity 138 , the second installation cavity 139 and the third installation cavity 140 are located on a side of the first passage 132 away from the placement compartment group 12 .

[0086] In the second direction, the first mounting cavity 138 , the second mounting cavity 139 and the third mounting cavity 140 are arranged in sequence, and the second channel 133 is located between the first mounting cavity 138 and the third mounting cavity 140 .

[0087] In the height direction of the energy storage cabinet 10 , the second installation cavity 139 is located at the lower side of the second channel 133 , and the height direction of the energy storage cabinet 10 is perpendicular to the first direction and the second direction respectively.

[0088] The first installation cavity 138 , the second installation cavity 139 , the third installation cavity 140 and the air guide passage 131 are isolated from each other.

[0089] like Figure 4 and Fig.10 As shown, at least four relatively independent spaces can be partitioned in the electrical compartment 13 , namely, an air guide channel 131 , a first installation cavity 138 , a second installation cavity 139 and a third installation cavity 140 .

[0090] The first channel 132 , the first installation cavity 138 , and the third installation cavity 140 in the air guide channel 131 may connect the top surface and the bottom surface of the energy storage cabinet 10 in the height direction.

[0091] The first channel 132 may be close to the placement compartment group 12, and the second channel 133, the first installation cavity 138, the second installation cavity 139, and the third installation cavity 140 may be arranged on a side of the first channel 132 away from the placement compartment group 12. The first installation cavity 138, the second installation cavity 139, and the third installation cavity 140 may be arranged in sequence along the second direction. The first installation cavity 138 may be close to the front of the electrical compartment 13, and the third installation cavity 140 may be close to the back of the electrical compartment 13.

[0092] In the height direction of the energy storage cabinet 10 , the second channel 133 may be located above the second installation cavity 139 .

[0093] In this embodiment, on the basis of the air guide channel 131 provided in the electrical compartment 13, the electrical compartment 13 is divided into a plurality of installation cavities, and other electrical structures or mechanical mechanisms can be arranged in each installation cavity, so as to make full use of the space of the electrical compartment 13, which is beneficial to improving the space utilization rate of the heat dissipation energy storage container 100.

[0094] In addition, the first installation cavity 138, the second installation cavity 139, the third installation cavity 140 and the air guide channel 131 can be isolated from each other, that is, there is no direct gas exchange between the four, which can prevent the heat generated by the electrical structure or mechanical structure contained in each space from affecting each other.

[0095] According to some optional embodiments of the utility model, a second air outlet 136 and a third air outlet 137 are provided on the side of the electrical compartment 13 away from the placement compartment group 12, the second air outlet 136 is connected to the first installation cavity 138, and the third air outlet 137 is connected to the third installation cavity 140. The heat dissipation and energy storage container 100 also includes: a liquid cooling device 50, a fire-fighting device 70 and an electrical device 80.

[0096] The liquid cooling device 50 is disposed in the first installation cavity 138, and includes a second fan 51. The second fan 51 is opposite to the second air outlet 136, and the liquid cooling device 50 is used to dissipate heat from the storage compartment group 12. The fire fighting device 70 is disposed in the second installation cavity 139. The electrical device 80 is disposed in the second installation cavity 139.

[0097] Specifically, the second air outlet 136 and the third air outlet 137 can be arranged on a side surface of the electrical compartment 13 away from the placement compartment group 12. The liquid cooling device 50 arranged in the first installation cavity 138 can dissipate heat through the second air outlet 136, and the electrical device 80 arranged in the third installation cavity 140 can dissipate heat through the third air outlet 137.

[0098] A second fan 51 may be provided at the second air outlet 136. A compressor may be provided in the liquid cooling device 50. Since the compressor generates a large amount of heat when it is working, the second fan 51 may help the liquid cooling device 50 to dissipate heat quickly.

[0099] Optionally, the number of the second air outlet 136 and the number of the third air outlet 137 can be plural.

[0100] For example, Figure 4 As shown, the electrical compartment 13 may be provided with a plurality of second air outlets 136 , which may be arranged in a rectangular array. A grille may be provided on one side of the electrical compartment 13 away from the placement compartment group 12 , and the grille may be arranged corresponding to the third installation cavity 140 to form a third air outlet 137 .

[0101] The heat emitted by the fire-fighting device 70 during operation is relatively small, and no additional air outlet is required.

[0102] The liquid cooling device 50 can be used to dissipate heat from the battery module 20 placed in the compartment group 12 .

[0103] In this embodiment, the liquid cooling device 50 is arranged in the first installation cavity 138, the fire-fighting device 70 is arranged in the second installation cavity 139, and the electrical device 80 is arranged in the third installation cavity 140. This can isolate the control device 30, the liquid cooling device 50, the fire-fighting device 70 and the electrical device 80 from each other to prevent the heat emitted by each from affecting each other.

[0104] In addition, a liquid cooling device 50 is provided in the heat dissipation energy storage container 100, so that the placement compartment group 12 adopts liquid cooling to dissipate heat, and the electrical compartment 13 adopts air cooling to dissipate heat, and the two do not interfere with each other. Liquid cooling of the placement compartment 121 is conducive to improving the heat dissipation efficiency and ensuring the smooth operation of the battery module 20, and air cooling of the electrical compartment 13 is conducive to reducing costs. Therefore, the combination of air cooling and liquid cooling can reduce costs and increase efficiency.

[0105] In some specific embodiments of the present invention, each storage compartment 121 is provided with an inlet valve 123 and an exhaust valve 124, and the inlet valve 123 and the exhaust valve 124 are respectively connected to the corresponding accommodation chamber 122. In the height direction of the energy storage cabinet 10, the inlet valve 123 is lower than the exhaust valve 124.

[0106] In case of emergency, independent exhaust can be achieved for a single compartment, so that the combustible gas can be quickly discharged from the nearest exhaust valve 124, thereby improving the safety of the energy storage cabinet 10 and preventing the combustible gas from affecting other storage compartments 121 and causing a chain reaction.

[0107] In addition, the air intake valve 123 is arranged to be lower than the exhaust valve 124, so that air can be taken in from the lower end of the storage compartment 121 and exhausted from the upper end, thereby quickly reducing the concentration of the combustible gas in the storage compartment 121. The multiple air intake valves 123 and exhaust valves 124 are arranged to replace the existing large exhaust structure, thereby improving the space utilization of the cabinet body and reducing the floor space occupied by the energy storage cabinet 10 and the energy storage cabinet 10.

[0108] According to some optional embodiments of the utility model, each storage compartment 121 is provided with doors 125 at both ends in the second direction, one of the two doors 125 of each storage compartment 121 is provided with an air intake valve 123, and the other of the two doors 125 of each storage compartment 121 is provided with an exhaust valve 124.

[0109] According to some other embodiments of the present invention, the air intake valve 123 is lower than the center of the storage cabin 121, and the exhaust valve 124 is higher than the center of the storage cabin 121. Therefore, the height difference between the air intake valve 123 and the exhaust valve 124 can be increased, which is beneficial for the complete discharge of the combustible gas in the storage cabin 121 and reduces the risk of cabin explosion.

[0110] In some specific embodiments of the present invention, in the height direction of the energy storage cabinet 10 , the top of the first partition 15 is spaced apart from the top of the cabinet body to form an air passage to communicate with the accommodating cavity 122 .

[0111] Specifically, the cabinet can be roughly in the shape of a cuboid, the length direction of the cuboid can be the first direction, the width direction of the cuboid can be the second direction, and the height direction of the cuboid can be the third direction. A top plate 111 can be provided on the top of the cabinet, and the first plate body and the lower surface of the top plate 111 can be spaced apart to form an air passage to connect two adjacent accommodating chambers 122.

[0112] Therefore, part of the combustible gas can flow into other storage compartments 121 through the gas passage, and exhaust is performed by using the intake valve 123 and the exhaust valve 124 in other storage compartments 121, which is conducive to quickly reducing the concentration of combustible gas in the energy storage cabinet 10.

[0113] According to some optional embodiments of the present utility model, in the first direction, an electrical compartment 13 is provided at one end of the compartment group 12 , and an explosion-proof valve 14 is provided at the other end of the compartment group 12 .

[0114] When the concentration of the combustible gas in the storage chamber group 12 exceeds the second threshold, the explosion-proof valve 14 can be opened to prevent explosion. The second threshold is greater than the first threshold. Optionally, the first threshold and the second threshold can be range values, respectively, and the maximum value within the first threshold range is less than the minimum value within the second threshold range.

[0115] In this embodiment, the explosion-proof valve 14 is arranged on the side of the storage compartment group 12 away from the electrical compartment 13. When the combustible gas is exhausted through the explosion-proof valve 14, the exhaust direction is away from the electrical compartment 13, which can prevent the explosion discharge of the storage compartment group 12 from affecting the electrical compartment 13. At the same time, when an abnormality occurs in the electrical compartment 13, it can also avoid affecting the storage compartment group 12, which is beneficial to improve the safety of the energy storage cabinet 10.

[0116] According to some other embodiments of the utility model, a detector may be provided in the storage compartment 121, and a controller may be provided in the fire fighting device 70. The detector is provided in each storage compartment 121, and is used to detect the concentration of the combustible gas in the accommodating cavity 122. The controller is electrically connected to the exhaust valve 124, the intake valve 123 and the detector, respectively, to control the on and off of the exhaust valve 124 and the intake valve 123 according to the detection results of the detector.

[0117] Specifically, a detector may be provided in each storage compartment 121, and the detector may be used as a part of the fire fighting device 70, and the detector may detect the concentration of the combustible gas in the corresponding storage compartment 121. The detector may be connected to the controller and send the detection result to the controller.

[0118] The controller can be connected to each air intake valve 123 and exhaust valve 124 on the cabinet respectively, and control the corresponding air intake valve 123 and exhaust valve 124 to open or close according to the detection result of each detector, so as to realize separate exhaust of each electrical compartment 13 to avoid affecting the battery modules 20 in other placement compartments 121 and causing a chain reaction.

[0119] In this embodiment, since the detector detects each placement compartment 121 individually, the detection space is smaller, so the detection accuracy is more precise and the possibility of misjudgment can be reduced.

[0120] In summary, the heat dissipation energy storage container 100 of the embodiment of the utility model can separate the battery module 20 from the control device 30 in the electrical compartment 13 to avoid mutual influence between the two. At the same time, the air cooling device can guide the cold air to flow in from the air inlet 134, and the hot air is discharged outward from the side of the electrical compartment 13 away from the placement compartment group 12. The use of air cooling to dissipate the heat of the electrical compartment 13 can not only reduce the cost of the heat dissipation energy storage container 100, but also avoid the heat generated by the electrical compartment 13 from having a thermal impact on the battery module 20 in the placement compartment 121, thereby preventing the battery module 20 from thermal runaway. Providing multiple air inlets 134 can improve the heat dissipation efficiency, make the heat dissipation more uniform, and avoid high temperature accumulation in the electrical compartment 13.

It should be understood by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present invention.
