[0036] The power distribution cabinet and energy storage vehicle provided by the embodiments of the present invention are described in detail below with reference to the accompanying drawings through specific embodiments and their application scenarios.

[0037] Reference Figure 1 and Figure 3 An embodiment of the present utility model provides a heat dissipation device for an energy storage cabin, comprising a cabin body 1, a first fan 21, and a second fan 22; the cabin body 1 is divided into an air inlet cabin 11 and a heat dissipation cabin 12, the air inlet cabin 11 has an air inlet communicating with the outside, the air outlet of the air inlet cabin 11 is communicated with the air inlet of the heat dissipation cabin 12, and the heat dissipation cabin 12 provides an installation space for the energy storage device 3; the first fan 21 is arranged in the installation space, and is used to guide the gas from the air inlet cabin 11 to the heat dissipation cabin 12 to dissipate heat for the energy storage device 3, and the second fan 22 is arranged at the air outlet of the heat dissipation cabin 12, and is used to discharge the gas in the heat dissipation cabin 12.

[0038] Specifically, if Figure 1 and Figure 3As shown, the cabin 1 is the main body for installing the energy storage device inside the mobile energy storage vehicle. It has a fixed support installation function and is a frame structure formed by overlapping multiple crossbeams and longitudinal beams. The cabin 1 is separated into an air inlet cabin 11 and a heat dissipation cabin 12 by a partition or beam structure. The air inlet of the air inlet cabin 11 is connected to the outside world, and the air outlet of the air inlet cabin 11 is connected to the air inlet of the heat dissipation cabin 12. When this heat dissipation device is applied to the energy storage vehicle, the relatively cold air from the outside enters the air inlet cabin 11 from the bottom of the energy storage vehicle through the air inlet of the air inlet cabin 11. The heat dissipation cabin 12 has an installation space for the energy storage device 3. The energy storage device 3 includes but is not limited to a battery pack, PCS or capacitor. During its operation, it will generate heat and heat up. To ensure safe operation, heat dissipation and cooling are required. Except for the connection point of the air outlet, other positions between the air inlet cabin 11 and the heat dissipation cabin 12 are equipped with barriers to prevent the incoming cold air from being discharged directly from the outlet of the heat dissipation cabin 12 without passing through the energy storage device. The first fan 21 and the second fan 22 are installed in the heat dissipation chamber 12. The first fan 21 is located in the installation space and is connected to the energy storage device. The second fan 22 is located at the air outlet of the heat dissipation chamber 12. It should be noted that the fans can be replaced with fans with the same function. Both the first fan 21 and the second fan 22 are axial flow fans, and the power of the second fan 22 is greater than that of the first fan 21. A small cooling fan can be used for the first fan 21.

[0039] In some embodiments, as Figure 1 and Figure 2 As shown, the airflow process within the cabin is as follows: cooler air from the outside is drawn in through the vents at the bottom of the energy storage vehicle and enters the air inlet compartment 11 through the air inlet of the air inlet compartment 11. Guided by the first fan 21, the air flows from the air outlet of the air inlet compartment 11 to the air inlet of the heat dissipation compartment 12, and then enters the heat dissipation compartment 12. The air entering the heat dissipation compartment 12 exchanges heat with the energy storage device 3, cooling the energy storage device 3 and increasing the air temperature. Guided by the second fan 22, the air is then discharged from the air outlet of the heat dissipation compartment 12.

[0040] The energy storage cabin heat dissipation device provided in the embodiment of the present invention adopts a natural air cooling heat dissipation method. By designing an air inlet cabin and a heat dissipation cabin that are isolated from each other, air flow is achieved under the action of a fan, heat exchange occurs with the energy storage device, and the temperature of the energy storage device is effectively reduced. Compared with the related technology of setting air conditioner cooling, there is no need to design an additional air conditioner, which reduces the occupied space and reduces the system energy consumption.

[0041] Optionally, refer to Figure 3 The cabin body 1 is further separated into an exhaust cabin 13; the air inlet of the exhaust cabin 13 is connected to the air outlet of the heat dissipation cabin 12, and the air outlet of the exhaust cabin 13 is connected to the outside world.

[0042] Specifically, if Figure 3As shown, the cabin body 1 has an exhaust cabin 13, which is adjacent to the heat dissipation cabin 12. Unlike the heat dissipation cabin 12, the exhaust cabin does not have the energy storage device 3 or other electrical components installed. The air inlet of the exhaust cabin 13 is connected to the air outlet of the heat dissipation cabin 12, and the air outlet of the exhaust cabin 13 is connected to the outside world. The gas entering the heat dissipation cabin 12 is discharged from the air outlet of the heat dissipation cabin 12 into the exhaust cabin 13 under the guidance of the second fan 22, and is finally discharged to the outside world through the air outlet of the exhaust cabin 13. The exhaust cabin 13 provides ample exhaust space, effectively improving the heat dissipation efficiency and reducing the temperature of the energy storage device.

[0043] Optionally, refer to Figure 3 , further comprising a third fan 23 ; the third fan 23 is disposed at the air outlet of the exhaust compartment 13 for discharging the gas in the exhaust compartment 13 .

[0044] Specifically, if Figure 3 As shown, the third fan 23 is arranged at the air outlet of the exhaust cabin 13, and is used to discharge the gas in the exhaust cabin 13. Therefore, the colder gas from the outside is collected from the vent at the bottom of the energy storage vehicle, and enters the air inlet cabin 11 through the air inlet of the air inlet cabin 11. Under the guidance of the first fan 21, the gas enters the heat dissipation cabin 12 to dissipate heat and cool the energy storage device 3. Subsequently, under the guidance of the second fan 22, the gas is discharged from the air outlet of the heat dissipation cabin 12 to the exhaust cabin 13. Finally, under the guidance of the third fan 23, the gas in the exhaust cabin 13 is discharged to the atmosphere. In this embodiment, the third fan 23 is an axial flow strong exhaust fan. In order to facilitate exhaust and improve heat dissipation efficiency, the air outlet of the exhaust cabin 13 is set at the top. And the power of the third fan 23 is greater than that of the second fan 22. Optionally, refer to Figure 1 and Figure 2 , a barrier component 14 is provided in the cabin body 1; the barrier component 14 is located between the air inlet cabin 11 and the heat dissipation cabin 12 to isolate the area outside the air outlet of the air inlet cabin 11 and the air inlet of the heat dissipation cabin 12.

[0045] Specifically, if Figure 1 and Figure 2As shown, a barrier assembly 14 is provided in the cabin 1. To achieve sufficient heat dissipation and cooling of the energy storage device 3, the gas needs to flow from the air outlet of the air inlet cabin 11 to the air inlet of the heat dissipation cabin 12, and fully exchange heat through the energy storage device 3. Therefore, to avoid heat dissipation failure caused by a short circuit in the air duct, a barrier measure is added to the cabin 1. After the colder air from the outside is introduced through the vent at the bottom of the energy storage vehicle, a barrier assembly 14 is provided to prevent the gas from being directly drawn away by the second fan 22 without passing through the energy storage device 3. This separates the air inlet cabin 11 from the heat dissipation cabin 12, so that all structures except the connection point between the air outlet of the air inlet cabin 11 and the air inlet of the heat dissipation cabin 12 are isolated. The gas entering the air inlet cabin 11 can only flow along the designed route from the air outlet of the air inlet cabin 11 to the air inlet of the heat dissipation cabin 12, and then flow through the energy storage device 3, effectively dissipating heat and cooling it, thereby improving the heat dissipation efficiency. The baffle assembly 14 may be an integral structure, or an assembled structure formed by splicing a plurality of baffles.

[0046] Optionally, refer to Figure 2 The barrier assembly 14 includes a first partition 141 and a second partition 142 that are connected to each other; there is an angle between the first partition 141 and the second partition 142, the first partition 141 is located on one side adjacent to the air outlet of the air inlet compartment 11, and the second partition 142 is located on the other side adjacent to the air outlet of the air inlet compartment 11.

[0047] Specifically, if Figure 2 As shown, the barrier assembly 14 of this embodiment is formed by connecting a first partition 141 and a second partition 142. Figure 2 As shown in the figure, the gas flow in the air inlet compartment 11 is along the X direction. For the convenience of explanation, the X direction is defined here as the front-to-back direction, the Y direction is the left-to-right direction, and the Z direction is the up-down direction. The air outlet of the air inlet compartment 11 is located at the front side of the air inlet compartment 11. To isolate the air inlet compartment 11 from the heat dissipation compartment 12, partitions are provided on the left and right sides and the upper and lower sides of the air inlet compartment 11. The first partition 141 is located on the left and / or right side of the air inlet compartment 11, and the second partition 142 is located on the upper and / or lower side of the air inlet compartment 11. There is a certain angle between the first partition 141 and the second partition 142, which can be 60°, 80°, 80°, or 90°. In this embodiment, this angle is set to 90°, that is, the first partition 141 and the second partition 142 are perpendicular to each other. The first partition 141 and the second partition 142 are used to prevent the gas entering the air inlet compartment 11 from being directly drawn away by the second fan 22 without passing through the energy storage device 3.

[0048] Optionally, refer to Figure 2 , further comprising an air duct 41, wherein there are at least two cabins 1; the air duct 41 is connected between the heat dissipation cabins 12 of the two cabins 1, connecting the heat dissipation cabins 12 of the two cabins 1.

[0049] Specifically, if Figure 2 As shown, there are at least two pods 1, each used to house a distributed PCS. An air duct 41 is provided between two adjacent pods 1. One end of the duct 41 communicates with the heat dissipation pod 12 of one pod 1, and the other end of the duct 41 communicates with the heat dissipation pod 12 of the other pod 1. This allows the heat dissipation pods 12 of each pod 1 to form a single heat dissipation chamber, facilitating exhaust from the outlet of a single exhaust pod 13, thus avoiding the need to design a separate exhaust pod 13 for each heat dissipation pod 12.

[0050] Optionally, refer to Figure 2 , also includes a third partition 42; the third partition 42 is connected to the cabin body 1, and the third partition 42 is arranged around the opening on the side of the heat dissipation cabin 12, and the third partition 42 is used to be connected to the wall of the energy storage cabin so that the third partition 42 and the wall of the energy storage cabin block the opening on the side of the heat dissipation cabin 12.

[0051] Specifically, if Figure 2 As shown, the heat dissipation chamber 12 has an opening on its side. A third partition 42 is disposed between the side opening of the heat dissipation chamber 12 near the wall and the wall. The third partition 42 surrounds the opening along the circumference of the side opening of the heat dissipation chamber 12. The third partition 42 and the wall shield the side opening of the heat dissipation chamber 12, forming an air duct within the heat dissipation chamber. The second fan 22 is located within this air duct to exhaust the gas within the heat dissipation chamber 12. Therefore, the installation of the third partition 42 allows the air duct within the heat dissipation chamber 12 to be formed by utilizing the wall of the energy storage chamber, eliminating the need to install a whole partition on the side of the heat dissipation chamber 12, thereby reducing material costs.

[0052] The embodiment of the present utility model further provides an energy storage cabin, comprising an energy storage device 3 and the energy storage cabin heat dissipation device in the above embodiment, wherein the energy storage device 3 is fixed in the heat dissipation cabin 12 .

[0053] Specifically, in an energy storage compartment equipped with the energy storage compartment heat dissipation device described in the above embodiment, cooler air from the outside enters through the air inlet of the air inlet compartment. Under the guidance of the first fan, the air enters the heat dissipation compartment, dissipating heat and cooling the energy storage device. Under the guidance of the second fan, the heated air is discharged from the heat dissipation compartment's air outlet. This utility model utilizes natural air cooling to dissipate heat. By designing mutually isolated air inlet and heat dissipation compartments, the fans create airflow, effectively reducing the temperature of the energy storage device. Compared to related technologies that use external air conditioners for cooling, this eliminates the need for an additional air conditioner, thus reducing space usage and system energy consumption.

[0054] Optionally, refer to Figure 1 One end of the energy storage device 3 is provided with an air inlet 31 , one end of the energy storage device 3 is located at the air inlet of the heat dissipation compartment 12 , and the other end of the energy storage device 3 is connected to the first fan 21 .

[0055] Specifically, if Figure 1 As shown, one end of the energy storage device 3 is located at the air inlet of the heat dissipation chamber 12. This end of the energy storage device 3 is provided with a polygonal air inlet 31, with multiple air inlet 31 arranged in an array. The other end of the energy storage device 3 is connected to a first fan 21. Under the guidance of the first fan 21, cooler air from the outside enters through the air inlet 31 of the energy storage device 3 and is discharged into the heat dissipation chamber 12 by the first fan 21. A fourth partition 5 is also provided within the chamber 1 to separate the energy storage device 3 from the battery pack above.

[0056] An embodiment of the present utility model further provides an energy storage vehicle, comprising the energy storage cabin described in any one of the above embodiments.

[0057] In the energy storage vehicle provided in this embodiment, the energy storage converter is located at the bottom of each battery cluster. Typically, eight battery clusters are provided. This is because eight compartments 1 are provided, each housing a corresponding battery cluster and an energy storage converter. Natural air cooling is used to reduce vehicle interior space and lower system energy consumption.
