Description

Technical Field

[0001] The present disclosure relates to the technical field of outdoor lithium battery devices, and in particular, to a rain-proof lithium battery cabinet and an outdoor lithium battery device. Background Art

[0002] An outdoor lithium battery device, that is, a lithium-ion battery device for preventing outdoors, generally includes a battery cabinet and a plurality of battery packs connected in series and parallel. Each battery pack is installed in the battery cabinet so that the battery pack can be protected from rain, and thus the battery cabinet is also called a rain-proof battery cabinet.

[0003] In related technologies, for example, CN116682212A - An outdoor energy storage battery cabinet. In order to improve the heat dissipation effect of the battery pack, heat dissipation holes are provided on the cabinet door of the battery cabinet for the battery pack to dissipate heat. To suppress the problem that the battery pack is short-circuited due to being wetted by rain, the size of the heat dissipation holes is usually designed to be small.

[0004] Although in most cases, the cabinet door can block rain from wetting the battery pack, when it is windy and rainy, the rain is more likely to enter the battery cabinet through the heat dissipation holes under the action of the wind, and then wet the battery pack, which may lead to a greater risk of short circuit of the battery pack when it is windy and rainy. Summary of the Utility Model

[0005] The purpose of the present disclosure is to overcome the deficiencies in the prior art, and to provide a rain-proof lithium battery cabinet and an outdoor lithium battery device that can further suppress the problem of the battery pack being wetted by rain, and thus avoid a greater risk of short circuit of the battery pack when it is windy and rainy.

[0006] The purpose of the present disclosure is achieved by the following technical solutions:

[0007] A rain-proof lithium battery cabinet includes a cabinet body and a cabinet door. A window is provided on the side surface of the cabinet body, and the cabinet door is rotatably connected to the window of the cabinet body. The cabinet door includes:

[0008] A panel, on which a plurality of heat dissipation holes are provided, and the plurality of heat dissipation holes are arranged in an array along the vertical direction;

[0009] A rain-blocking assembly, including a fixed frame and at least three rain-blocking plates. The fixed frame is fixedly connected to the inner side surface of the panel.

The at least three rain-blocking plates are located in the installation groove and fixedly connected to the fixed frame. A rain-blocking channel is formed between adjacent two rain-blocking plates, and the plurality of rain-blocking channels respectively communicate with the plurality of heat dissipation holes;

[0010] Wherein, each of the rain shields is arranged obliquely toward the panel, and each of the heat dissipation holes is located within the projection of the corresponding rain shield on the panel along the horizontal direction.

[0011] In some embodiments, the side edge of each rain shield adjacent to the panel is bent downward to form a connecting portion, and the connecting portion of each rain shield is in contact with the panel.

[0012] In some embodiments, the side of each rain shield facing away from the panel is bent upward to form a blocking portion, and a gap exists between the blocking portion of each rain shield and the adjacent rain shield.

[0013] In some embodiments, the rainproof lithium battery cabinet also includes a covering plate, which is fixedly connected to the panel at its periphery, a accommodating cavity is formed between the covering plate and the panel, the fixing frame is located in the accommodating cavity, and a heat conducting hole is formed on the covering plate, which is communicated with the mounting groove.

Moreover, since the rain shield is inclined toward the panel, the blocked rainwater can flow downward along the rain shield and finally be discharged through the heat dissipation holes. In this way, the problem of rainwater entering the cabinet and wetting the battery pack is further suppressed, thereby avoiding a greater risk of short circuit in the battery pack when it is windy and rainy.

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present disclosure belongs. The terms used herein in the specification of the present disclosure are only for the purpose of describing specific embodiments and are not intended to limit the present disclosure. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0038] To better understand the technical solutions and beneficial effects of the present disclosure, the present disclosure will be further described in detail below with specific embodiments:

[0039] As Figure 1 shown, a rain-proof lithium battery cabinet 10 in an embodiment includes a cabinet body 100 and a cabinet door 200. A window 101 is provided on the side surface of the cabinet body 100, and the cabinet door 200 is rotatably connected to the window 101 of the cabinet body 100.

[0040] As Figure 2 and Figure 3 shown, the cabinet door 200 includes a panel 210 and a rain-proof component 220. Among them, the rain-proof component 220 includes a fixed frame 221 and at least three rain-proof plates 222. The fixed frame 221 is fixedly connected to the inner side surface of the panel 210, that is, the fixed frame 221 is fixedly connected to the side surface of the panel 210 facing the inside of the cabinet body 100 when the cabinet door 200 is closed. An installation groove 2201 is formed by the limit between the fixed frame 221 and the panel 210.

[0041] As Figures 4 to 7As shown in the figure, the panel 210 is provided with a plurality of heat dissipation holes 211, and the plurality of heat dissipation holes 211 are arranged in an array in the vertical direction. Each heat dissipation hole 211 communicates with the installation groove 2201. At least three rain shields 222 are arranged in an array in the vertical direction. At least three rain shields 222 are located in the installation groove 2201 and are fixedly connected to the fixed frame 221. A rain shielding channel 2221 is formed between two adjacent rain shields 222, and the plurality of rain shielding channels 2221 communicate with the plurality of heat dissipation holes 211 respectively. Each rain shield 222 is inclined towards the panel 210, and each heat dissipation hole 211 is located within the projection of the corresponding rain shield 222 on the panel 210 in the horizontal direction.

[0042] As Figure 7 shown, in this embodiment, after the cabinet door 200 is closed, each rain shielding channel 2221 communicates with the interior of the cabinet body 100, and the heat generated by the battery pack 20 is dissipated through the rain shielding channel 2221 and the heat dissipation hole 211 in sequence. When it is windy and rainy, the wind blows the rain towards the heat dissipation hole 211, causing the rain to enter the rain shielding channel 2221 through the heat dissipation hole 211.

[0043] For the above rain-proof lithium battery cabinet 10, since each heat dissipation hole 211 is located within the projection of the corresponding rain shield 222 on the panel 210 in the horizontal direction, the rain shield 222 can block rainwater from entering the cabinet body 100, thereby preventing the rain shield 222 from wetting the battery pack 20. Also, because the rain shield 222 is inclined towards the panel 210, the blocked rainwater can flow downward along the rain shield 222 and finally be discharged through the heat dissipation hole 211. In this way, the problem of rainwater entering the cabinet body 100 and wetting the battery pack 20 is further suppressed, and the risk of a large short circuit of the battery pack 20 during windy and rainy weather is avoided.

[0044] As Figure 7 shown, in some embodiments, there are drainage holes (not shown in the figure) between each rain shield 222 and the panel 210, and each drainage hole communicates with the adjacent rain shielding channel 2221. In this embodiment, the rainwater blocked by the rain shield 222 can also flow through the drainage hole to the lower rain shielding channel 2221, improving the drainage efficiency.

[0045] As Figure 7 shown, in some embodiments, the side of each rain shield 222 adjacent to the panel 210 is bent downward to form a connecting portion 222a, and the connecting portion 222a of each rain shield 222 is attached to the panel 210, improving the position stability of each rain shield 222.

[0046] As Figure 7As shown, in some of these embodiments, a blocking portion 222b is formed by bending the side of each rain shield 222 away from the panel 210 upward. There is a gap between the blocking portion 222b of each rain shield 222 and the adjacent rain shield 222. The blocking portion 222b of each rain shield 222 is used to block rainwater, thus increasing the rain-blocking area of the rain shield 222 and improving the rain-blocking effect.

[0047] As Figure 7 shown, in some of these embodiments, the rain-proof lithium battery cabinet 10 further includes a cover plate 300. The periphery of the cover plate 300 is fixedly connected to the panel 210. An accommodation cavity 301 is formed between the cover plate 300 and the panel 210. The fixing frame 221 is located in the accommodation cavity 301. The cover plate 300 is formed with heat conduction holes 302, and the heat conduction holes 302 are communicated with the installation groove 2201, so that the heat conduction holes 302 are communicated with each rain-blocking channel 2221. In this embodiment, after the cover plate 300 is installed, the rain-blocking assembly 220 is arranged in the accommodation cavity 301 of the cover plate 300, so that the cover plate 300 plays a role in protecting the rain-blocking assembly 220.

[0048] As Figure 7 shown, in some of these embodiments, the number of the heat conduction holes 302 is multiple, and the multiple heat conduction holes 302 are arranged in an array.

[0049] As Figure 7 shown, in some of these embodiments, the heat conduction holes 302 are polygonal.

[0050] As Figure 7 shown, in some of these embodiments, the heat dissipation holes 211 are strip-shaped, improving the heat dissipation effect.

[0051] As Figure 7 shown, in some of these embodiments, the extending direction of the heat dissipation holes 211 is parallel to the horizontal direction.

[0052] As Figure 7 shown, in some of these embodiments, each rain shield 222 is welded to the fixing frame 221.

[0053] As Figure 1 shown, the present disclosure also provides an outdoor lithium battery device, including the rain-proof lithium battery cabinet 10 described in any of the above embodiments. The outdoor lithium battery device further includes a battery pack 20, and the battery pack 20 is arranged in the cabinet 100.

[0054] Compared with the prior art, the present disclosure has at least the following advantages:

[0055] For the above-mentioned rain-proof lithium battery cabinet 10, since each heat dissipation hole 211 is located within the projection of the corresponding rain shield 222 on the panel 210 in the horizontal direction, the rain shield 222 can block rainwater from entering the cabinet body 100, and thus the rain shield 222 can prevent the battery pack 20 from being wetted by rainwater. Also, because the rain shield 222 is inclined towards the panel 210, the blocked rainwater can flow downward along the rain shield 222 and finally be discharged through the heat dissipation hole 211. In this way, the problem of rainwater entering the interior of the cabinet body 100 and wetting the battery pack 20 is further suppressed, and a large short-circuit risk of the battery pack 20 in windy and rainy weather is avoided.

[0056] The above-described embodiments merely represent several implementation manners of the present disclosure. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the disclosed patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present disclosure, several modifications and improvements can still be made, and these all belong to the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure patent shall be subject to the appended claims.
