[0037] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0038] It should be noted that the terms used here are only for describing the specific implementation manners and are not intended to limit the exemplary implementation manners according to the present application. As used here, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form.

[0039] Unless otherwise specifically stated, the relative arrangement of components and steps, numerical expressions, and numerical values set forth in these embodiments do not limit the scope of the present application. At the same time, it should be understood that for the sake of convenience of description, the dimensions of the various parts shown in the drawings are not drawn in actual proportional relationship.

In all the examples shown and discussed here, any specific value should be construed as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0040] The air inlet and outlet structures of the ventilation mechanism 20 provided in the current energy storage cabinet are integrally arranged, so that the air inlet and outlet of the ventilation mechanism 20 are located at the same position, and the air cannot effectively circulate inside the cabinet, resulting in the air circulation and heat dissipation effect in the power energy storage cabinet still needing to be improved. In view of the above problems, the first embodiment of the present utility model provides an energy storage cabinet. Please refer to Figures 1 to 9 , the energy storage cabinet includes a cabinet body 10 and a ventilation mechanism 20. An installation cavity is provided inside the cabinet body 10, and devices such as an energy storage power supply and a power control module can be placed in the installation cavity. The ventilation mechanism 20 includes an air inlet component 21 and an air outlet component 22. The air inlet component 21 and the air outlet component 22 are both installed in the installation cavity and are at least spaced apart from each other along a first direction, where the first direction is the height direction of the cabinet body 10, that is Figure 1 the direction indicated by the arrow X in

[0041] It can be seen that the energy storage cabinet provided in this embodiment includes a cabinet body 10 and a ventilation mechanism 20. The ventilation mechanism 20 includes an air inlet component 21 and an air outlet component 22. Both the air inlet component 21 and the air outlet component 22 are installed in the installation cavity of the cabinet body 10 and are at least spaced apart from each other along a first direction, and the air outlet component 22 is located above the air inlet component 21 along the first direction. Since the air outlet component 22 is spaced apart from the air inlet component 21, after the air enters the installation cavity from the air inlet component 21, it will flow through a relatively long distance in the installation cavity and then flow out from the air outlet component 22. The air circulation range in the cabinet body 10 is wider, enabling the air to effectively circulate in the cabinet body 10, thereby effectively improving the heat dissipation effect of the ventilation mechanism 20 on the cabinet body 10. Moreover, when the temperature in the installation cavity of the energy storage cabinet is relatively high, due to the intensified thermal movement of the air molecules in the installation cavity, the air expands and the air density decreases. The air with reduced density rises and can be discharged in time through the air outlet component 22 located above the air inlet component 21, thereby effectively discharging the hot air inside the cabinet body 10 to the outside of the cabinet body 10, enabling the energy storage cabinet to have good ventilation and exhaust functions as well as heat dissipation performance. At the same time, it can also effectively balance the air pressure difference between the inside and outside of the energy storage cabinet, ventilate and exchange the air in the installation cavity of the energy storage cabinet, prevent dangerous situations such as explosion of the machine due to excessive air pressure inside the installation cavity, and avoid unnecessary safety accidents, thereby improving the safety of the energy storage cabinet product.

[0042] Secondly, to save the design space of the cabinet body 10, as Figures 1 to 2 well as Figure 6 shown, the cabinet body 10 in this embodiment includes a first mounting plate 11. Along the first direction, the first mounting plate 11 includes a first side 111 and a second side 112. The air inlet component 21 is installed on the first side 111, and the air outlet component 22 is installed on the second side 112. The second side 112 is located above the first side 111 along the first direction. That is to say, while setting the ventilation mechanism 20 into two independent air inlet components 21 and air outlet components 22 in this embodiment, the air inlet component 21 and the air outlet component 22 are spaced apart and installed on the first mounting plate 11 along the first direction, which can save the design space of the cabinet body 10, improve the space utilization rate of the cabinet body 10, and also make the energy storage cabinet product more in line with the modular design principle, facilitating the separate maintenance of the air inlet component 21 and the air outlet component 22. In addition, since the air inlet component 21 and the air outlet component 22 can be independently installed on the first mounting plate 11 at the same time, the assembly efficiency of the energy storage cabinet can also be improved. The first mounting plate 11 can be used as the rear door plate of the cabinet body 10, saving the design space of the cabinet body 10 and facilitating the opening of the first mounting plate 11 for the maintenance of the ventilation mechanism 20.

[0043] An air vent 12 is provided on the side wall of the cabinet body 10, and the air vent 12 is located at at least one of the air inlet assembly 21 and the air outlet assembly 22. Specifically, when both the air inlet assembly 21 and the air outlet assembly 22 are installed on the first mounting plate 11, the air vent 12 is specifically provided at the position of the first mounting plate 11 close to the air inlet assembly 21 and the air outlet assembly 22, so that the air inlet assembly 21 diverts the air entering through the air vent 12 into the installation cavity, and the air outlet assembly 22 discharges the air in the installation cavity out of the cabinet body 10 along the air vent 12.

[0044] Please refer to Figures 3 to 8 , in this embodiment, to improve the waterproof performance of the cabinet body 10, at least one of the air inlet assembly 21 and the air outlet assembly 22 includes a first mounting member 121. A first avoidance groove 211 and a communication part are provided on the first mounting member 121. The communication part is provided on one side of the first mounting member 121 away from the bottom of the installation cavity along the first direction and is communicated with the first avoidance groove 211. The first mounting member 121 is connected to the side wall of the cabinet body 10 so that the air vent 12 is located in the first avoidance groove 211. For the air inlet assembly 21, before the air enters the installation cavity of the cabinet body 10, the air first enters the first avoidance groove 211 along the air vent 12, and then enters the installation cavity from the communication part communicated with the first avoidance groove 211. For the air outlet assembly 22, before the air in the installation cavity is discharged out of the cabinet body 10, the air enters the first avoidance groove 211 along the communication part, and then is discharged out of the cabinet body 10 through the air vent 12 located in the avoidance groove.

[0045] In this embodiment, whether it is the air inlet assembly 21 or the air outlet assembly 22, since the communication part is located on one side of the first avoidance groove 211 away from the bottom of the installation cavity along the first direction, if rainwater enters the first avoidance groove 211 along the air vent 12, the rainwater will drip on the bottom of the first avoidance groove 211 away from the communication part along the first direction under the action of gravity, and it is difficult for the rainwater to enter the installation cavity from the communication part, so as to achieve the purpose of blocking the rainwater outside the installation cavity. Therefore, when the cabinet body 10 is under outdoor conditions, the first avoidance groove 211 provided in the first mounting member 121 can prevent rainwater from flowing into the installation cavity inside the cabinet body 10 and avoid damaging the devices in the installation cavity. That is to say, in this embodiment, through the ingenious design of the positional relationship between the communication part on the first mounting member and the first avoidance groove 211, the ventilation mechanism 20 can achieve the purpose of waterproofing without introducing relatively complex waterproof devices, reducing the design difficulty of the ventilation mechanism 20 and reducing the production cost of the ventilation mechanism 20. When both the air inlet assembly 21 and the air outlet assembly 22 achieve waterproofing through the first avoidance groove 211 in the first mounting member 121, the waterproof effect of the cabinet body 10 is better.

[0046] After foreign objects such as dust and impurity particles in the air enter the cabinet 10 along the air inlet component 21 or the air outlet component 22, these foreign objects enter the installation cavity, which will affect the heat dissipation effect of the ventilation mechanism 20 on the cabinet 10, and may even cause damage to the devices in the installation cavity. In this regard, in order to prevent external foreign objects from entering the installation cavity, the ventilation mechanism 20 in this embodiment also includes a filtering component. The filtering component is covered on the connecting portion, and the filtering component is used to prevent foreign objects outside the cabinet 10 from entering the installation cavity along the connecting portion. The filtering component can effectively prevent dust outside the cabinet 10 from entering the installation cavity inside the energy storage cabinet, avoid the installation cavity due to excessive dust causing the heat dissipation effect of the ventilation mechanism 20 to decrease, and avoid safety accidents such as fire caused by excessive temperature of the cabinet 10.

[0047] Specifically, the filter component in this embodiment includes a breathable cotton block 23 and a mounting block. The breathable cotton block 23 is laid on the first mounting member 121 and covers the connecting portion. The breathable cotton block 23 can not only block dust outside the installation cavity, but also ensure that air can penetrate the breathable cotton block 23 into the installation cavity to dissipate heat for the cabinet 10. The mounting block presses the breathable cotton block 23 onto the first mounting member 121, thereby preventing the breathable cotton block 23 from being offset relative to the connecting portion. In this embodiment, the breathable cotton block 23 can be specifically covered on the side of the connecting portion away from the first avoidance groove 211, and the installation is simple and convenient.

[0048] The connecting portion may include a larger avoidance opening provided on the mounting member. Since the breathable cotton block 23 is relatively soft, the breathable cotton block 23 is prone to collapse when covered on the larger avoidance opening. In order to better lay the breathable cotton block 23 on the connecting portion, the connecting portion in this embodiment includes a plurality of first through holes 212, and the first mounting member 121 includes a first side plate 213, and the first side plate 213 is located on a side of the first mounting member 121 close to the filter component. A plurality of first through holes 212 are provided through the first side plate 213 and are connected to the first avoidance groove 211. The breathable cotton block 23 is laid on the first side plate 213 and covers the plurality of first through holes 212. A plurality of first through holes 212 form a honeycomb hole group structure on the first side plate 213, which can not only ensure that the air can flow into the installation cavity through the first through holes 212, but also the area between adjacent first through holes 212 on the first side plate 213 can provide a balanced and stable supporting force to the breathable cotton block 23, ensuring that the breathable cotton block 23 will not collapse significantly and affect the dustproof effect.

[0049] The air inlet assembly 21 in this embodiment includes a first mounting member 121 and a filter member, wherein Figure 3 and Figure 5As shown in the figure, the mounting block includes a first mounting block 24 located in the air inlet assembly 21. A plurality of second through holes 241 communicating with the communication part are provided on the first mounting block 24. The first mounting block 24 covers the breathable cotton block 23 and makes the second through holes 241 disposed opposite to the breathable cotton block 23. And the first mounting block 24 is misaligned with at least one side of the breathable cotton block 23 and connected to the side wall of the cabinet 10, and at least the other side is connected to the first mounting member 121. Thus, in the air inlet assembly 21 provided in this embodiment, the first mounting block 24 provided with a plurality of second through holes 241 covers the breathable cotton block 23 to improve the firm reliability of the installation of the breathable cotton block 23 on the first mounting member 121. Moreover, the first mounting block 24 is respectively connected to the side wall of the cabinet 10 (specifically the first mounting plate 11) and the first mounting member 121, which not only realizes the connection of the air inlet assembly 21 and the cabinet 10, but also enables the first mounting block 24 to press the breathable cotton block 23 more stably.

[0050] In this embodiment, the air inlet assembly 21 composed of the first mounting member 121 and the filtering component has a simple and compact structure, is convenient and fast to install, and can ensure that the air outside the cabinet 10 can enter the installation cavity along the air inlet assembly 21, and at the same time, the breathable cotton block 23 of the filtering component can prevent dust, impurity particles, etc. outside the cabinet 10 from entering the installation cavity. Meanwhile, the first avoidance groove 211 of the first mounting member 121 can also prevent water from entering the installation cavity, improving the waterproof performance of the air inlet assembly 21, and further improving the waterproof performance of the cabinet 10.

[0051] The air outlet assembly 22 in this embodiment includes a first mounting member 121 and a filtering component, such as Figure 7 and Figure 9 As shown in the figure, the mounting block further includes a second mounting block 25 located in the air outlet assembly 22. A plurality of third through holes 251 communicating with the communication part are provided on the second mounting block 25. The second mounting block 25 covers the breathable cotton block 23 and makes the third through holes 251 disposed opposite to the breathable cotton block 23. Thus, in the air outlet assembly 22 provided in this embodiment, the second mounting block 25 provided with a plurality of third through holes 251 covers the breathable cotton block 23 to improve the firm reliability of the installation of the breathable cotton block 23 on the first mounting member 121. The air outlet assembly 22 further includes an exhaust component 221. The exhaust component 221 is installed on one side of the first mounting member 121 close to the communication part, and the exhaust component 221 and the second mounting block 25 are misaligned and connected to at least one side of the breathable cotton block 23, so that the second mounting block 25 can stably and reliably press the breathable cotton block 23 on the first mounting member 121. The exhaust component 221 in this embodiment is used to discharge the air in the installation cavity to the outside of the cabinet 10 along the third through holes 251, the communication part and the ventilation port 12 in sequence, so that the ventilation mechanism 20 can discharge the hot air in the installation cavity in time and effectively through the exhaust component 221, improving the heat dissipation efficiency of the ventilation mechanism 20.

[0052] Please refer to Figure 1 and Figure 7 , the exhaust component 221 includes a second mounting member 2211 and an exhaust fan 2212. The second mounting member 2211 is connected to the first mounting member 121 and the side wall of the cabinet body 10. The second mounting member 2211 is provided with a second avoidance groove 2111 and a mounting hole 2112. The second avoidance groove 2111 is located on one side of the second mounting member 2211 close to the side wall of the cabinet body 10 and encloses an exhaust cavity with the side wall of the cabinet body 10. The exhaust cavity is communicated with the third through hole 251. The mounting hole 2112 is located on the side of the second mounting member 2211 away from the side wall of the cabinet body 10 and is communicated with the exhaust cavity. The exhaust fan 2212 is installed at the mounting hole 2112. Thus, the air in the installation cavity can be sucked into the exhaust cavity by the exhaust fan 2212, and then discharged to the outside of the cabinet body 10 through the third through hole 251 communicated with the exhaust cavity, the connecting part, and the ventilation port 12 on the first mounting plate 11. The exhaust component 221, the first mounting member 121, and the air outlet assembly 22 formed by the filter component have a simple and compact structure, are convenient and fast to install, can timely discharge the air in the installation cavity to the outside of the cabinet body 10, and can also prevent dust, impurity particles, etc. outside the cabinet body 10 from entering the installation cavity through the breathable cotton block 23 of the filter component. At the same time, the first avoidance groove 211 of the first mounting member 121 can also prevent water from entering the installation cavity, improving the waterproof performance of the air outlet assembly 22, and further improving the waterproof performance of the cabinet body 10.

[0053] In addition, the breathable cotton block 23 in this embodiment includes a polyester fiber cotton block. The polyester fiber cotton block is a synthetic fiber cotton made by chemically polycondensing organic dibasic acids and dibasic alcohols. It has a high melting point, good light resistance and heat resistance. When in use, it has a high elastic modulus, a stable shape, is not easy to wear and deform, and has a long service life. And the polyester fiber cotton block has a certain waterproof property, which can avoid the ventilation mechanism 20 from malfunctioning due to moisture during use, improving the comprehensive safety performance of the energy storage cabinet product.

[0054] As can be seen from the above, the energy storage cabinet provided in this embodiment has the following advantages:

[0055] 1) Ingenious structural design: The ventilation mechanism 20 of this energy storage cabinet is ingeniously designed. The air inlet component 21 and the air outlet component 22 are respectively designed as independent modules and are each installed on the first mounting plate 11 which serves as the rear door panel, saving the design space of the cabinet body 10 and making the energy storage cabinet product more in line with the modular design principle. Since the internal temperature of the energy storage cabinet is relatively high during operation and the gas will rise, the air inlet component 21 is designed on the first side 111 below the rear door panel, and the air outlet component 22 is designed on the second side 112 above the rear door panel, which can effectively discharge the hot air inside the cabinet body 10 and has good ventilation and exhaust functions and heat dissipation. Moreover, when the energy storage cabinet is under outdoor conditions, the first avoidance groove 211 provided on the first mounting member 121 of the air inlet component 21 and the air outlet component 22 of the ventilation mechanism 20 can prevent rainwater from flowing into the installation cavity of the cabinet body 10 and avoid damaging the devices inside the installation cavity.

[0056] 2) Convenient installation: Since the air inlet component 21 and the air outlet component 22 of the ventilation mechanism 20 are two independent module units, the air inlet component 21 and the air outlet component 22 can be independently installed simultaneously during installation, saving installation time and improving the assembly efficiency and production efficiency of the energy storage cabinet.

[0057] 3) High applicability: The ventilation mechanism 20 of this energy storage cabinet can be applied to energy storage cabinets of different models, improving the scope of use of the product and having strong applicability.

[0058] 4) High safety: The ventilation mechanism 20 of this energy storage cabinet can effectively balance the air pressure difference between the inside and outside of the energy storage cabinet, ventilate and exchange the air in the installation cavity of the energy storage cabinet, and prevent dangerous situations such as explosion of the cabinet body 10 due to excessive air pressure inside, causing unnecessary safety accidents, thereby improving the safety of the energy storage cabinet product and making the product more in line with safety standards. Moreover, the ventilation mechanism 20 of this energy storage cabinet is equipped with a breathable cotton block 23 for dust prevention at each of the air inlet component 21 and the air outlet component 22. The breathable cotton block 23 can effectively prevent dust outside the energy storage cabinet from entering the installation cavity, avoid affecting the heat dissipation effect of the ventilation mechanism 20 on the cabinet body 10 due to excessive dust, and avoid safety accidents such as fire caused by the cabinet body 10 due to too high temperature.

[0059] 5) Good product durability: The dust-proof cotton in the ventilation mechanism 20 of this energy storage cabinet uses a polyester fiber cotton block. The polyester fiber cotton block is a synthetic fiber made by chemical polycondensation of organic dibasic acids and dibasic alcohols, with a high melting point, good light resistance and heat resistance, high elastic modulus, stable shape, not easy to wear and deform during use, and a long service life. Moreover, the polyester fiber cotton block has certain waterproofness, which can avoid failures of the ventilation mechanism 20 due to moisture during use, improving the comprehensive safety and reliability of the energy storage cabinet product.

[0060] For ease of description, spatial relative terms, such as "above", "over", "on the upper surface", "upper", etc., may be used herein to describe the spatial positional relationship of one device or feature to other devices or features as shown in the figures. It should be understood that the spatial relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the figures.
