Referring to Fig. 1, Fig. 2 and Fig. 3, the utility model provides an outdoor energy storage cabinet, including a cabinet 1, a shell 2, a dustproof structure 3 and a waterproof structure 4. The cabinet 1 is provided with a receiving cavity 11, and an air inlet 12 (see Fig. 5) is provided at the bottom of the cabinet 1, and the energy storage device is arranged in the receiving cavity 11. The shell 2 is arranged on the side of the cabinet 1 and is located at the upper end of the cabinet 1; the shell 2 is provided with a heat dissipation channel 21 connected with the receiving cavity 11, and the heat dissipation channel 21 is used to dissipate heat for the energy storage device. The dustproof structure 3 is arranged on the side of the shell 2 away from the receiving cavity 11, and the dustproof structure 3 is provided with an air outlet 31. The waterproof structure 4 is arranged on the shell 2 and is located in the receiving cavity 11; the waterproof structure 4 is provided with a unidirectional guide groove 41, which is connected with the heat dissipation channel 21 and the receiving cavity 11, and the unidirectional guide groove 41 is used to guide the flow direction of water entering from the heat dissipation channel 21.

Among them, the direction in which the dustproof structure 3, the shell 2 and the waterproof structure 4 are arranged in sequence is taken as the first direction X, and the plane perpendicular to the first direction X is taken as the reference plane. The orthographic projection of the dustproof structure 3 on the reference plane and the orthographic projection of the waterproof structure 4 on the reference plane can respectively cover the orthographic projection of the heat dissipation channel 21 on the reference plane.

In this way, by setting the air inlet 12 at the bottom of the cabinet 1 and setting the air outlet 31 on the dustproof structure 3, since the shell 2 is set at the upper end of the cabinet 1, and the dustproof structure 3 is set on the shell 2, that is, the air outlet 31 is located at the upper end of the cabinet 1, the cold air outside the cabinet 1 enters the accommodating cavity 11 from the air inlet 12, and performs heat exchange with the heat generated by the energy storage device to reduce the temperature of the energy storage device. According to the principle that hot air rises, the hot air formed after the heat exchange rises and is discharged from the accommodating cavity 11 from the heat dissipation channel 21 and the air outlet 31. Since the heat is not dissipated through the air conditioning system or the liquid cooling device, the energy consumption for heat dissipation can be saved; By connecting the one-way guide groove 41 with the heat dissipation channel 21 and the accommodating chamber 11, the energy storage device can be cooled; by setting a dustproof structure 3 at the heat dissipation channel 21, dust and the like can be prevented from entering the accommodating chamber 11; by setting a waterproof structure 4 at the heat dissipation channel 21, the waterproof structure 4 is provided with a one-way guide groove 41. In rainy and snowy weather, if water enters the heat dissipation channel 21, the waterproof structure 4 can block water and prevent water from flowing into the accommodating chamber 11. The blocked water is discharged from the cabinet 1 along the one-way guide groove 41, so that the outdoor energy storage cabinet can be used normally in severe weather conditions such as sandstorms, typhoons, heavy rain and snow. Moreover, the protection level of the outdoor energy storage cabinet of the utility model reaches IP55 and NEMA3.

Referring to FIG. 1 and in combination with FIG. 3 , in some embodiments, the waterproof structure 4 includes a main frame 42, a guide plate 43, two first side plates 44 and a second side plate 45. Specifically, the main frame 42 is disposed on the side of the shell 2 facing the accommodating chamber 11. The guide plate 43 is disposed at the bottom end of the main frame 42 along the second direction Y; the angle between the guide plate 43 and the bottom end of the main frame 42 is an acute angle. The two first side plates 44 are respectively disposed at the opposite ends of the main frame 42 along the third direction Z. The second side plate 45 is connected between the two first side plates 44. Among them, the guide plate 43, the two first side plates 44 and the second side plate 45 enclose a one-way guide groove 41; the first direction X, the second direction Y and the third direction Z are perpendicular to each other.

It can be understood that the main frame 42, the guide plate 43, the two first side plates 44 and the second side plate 45 can be fixedly connected to each other by welding, fasteners 35, etc., or the entire waterproof structure 4 can be directly set as an integrally formed structure. The waterproof structure 4 can meet the actual use requirements and no excessive restrictions are made here.

It should be noted that the angle between the guide plate 43 and the bottom end of the main support 42 is an acute angle, that is, the guide plate 43 is tilted to guide the water so that the water entering through the heat dissipation channel 21 can be discharged along the guide plate 43. The size of the acute angle can be set as needed and is not limited here. In order for the guide plate 43 to guide the water to flow out through the heat dissipation channel 21, the lower end of the guide plate 43 cannot be lower than the bottom of the heat dissipation channel 21 along the flow direction of the water, otherwise, the water will accumulate in the one-way guide groove 41, which is not conducive to drainage.

In this way, by providing the waterproof structure 4, water can be blocked from entering the accommodating cavity 11; by providing the guide plate 43, water falls onto the guide plate 43 under the action of gravity, and since the guide plate 43 is inclined, the water can be guided to smoothly discharge from the accommodating cavity 11, thereby protecting the energy storage equipment located in the accommodating cavity 11, improving the waterproof level of the outdoor energy storage cabinet, and being able to be used normally even in rainy and snowy weather.

Referring to FIG. 1 and FIG. 4 , in some embodiments, a baffle 5 is provided on the housing 2, and along the second direction Y, the connection between the baffle 5 and the housing 2 is located above the heat dissipation channel 21; the angle between the baffle 5 and the bottom end of the main support 42 is an acute angle, and the baffle 5 is located in the accommodating cavity 11. Further, in some embodiments, the baffle 5 and the second side plate 45 are parallel to each other.

In this way, by providing the baffle 5, the baffle 5 can block a portion of water from entering the waterproof structure 4, which is beneficial to further improve the waterproof capability of the outdoor energy storage cabinet.

Referring to FIG. 1 and FIG. 4 , in some embodiments, the dustproof structure 3 includes a first fixing plate 32, a second fixing plate 33 and a dustproof member 34. The dustproof member 34 is sandwiched between the first fixing plate 32 and the second fixing plate 33, and the first fixing plate 32 and the second fixing plate 33 are both arranged on the housing 2. The air outlet 31 is arranged on the first fixing plate 32 and the second fixing plate 33; the dustproof member 34 is made of a dustproof and breathable material.

Optionally, the dustproof member 34 is a dustproof sponge. It is understandable that the dustproof member 34 can meet the requirements of dustproof and breathable, and is not limited to dustproof sponge, and can also be made of other materials that meet the use requirements. Of course, in order to improve the dustproof effect, the dustproof structure 3 can also be provided with a filter screen, and can also be provided with multiple layers of dustproof members 34.

Thus, in this embodiment, by setting up a dustproof sponge, the dustproof sponge can achieve ventilation while blocking the passage of dust, thereby realizing heat dissipation of the energy storage equipment; when the rapids directly impact the dustproof structure 3, the dustproof sponge can also block water, reduce the flow rate of water, and guide water to the surroundings.

1 and 4 , in some embodiments, the dustproof structure 3 further includes a fastener 35, and the fastener 35 is disposed through the first fixing plate 32, the second fixing plate 33 and the housing 2. Optionally, the fastener 35 is a screw and/or a riveting stud.

It is understandable that the fastener 35 can be a single screw or a single riveting stud, or a screw and a riveting stud connected together. Of course, the fastener 35 can also select other connection structures, not limited to screws and riveting studs. In addition, in order to fix the dustproof member 34 and prevent the dustproof member 34 from shifting when the torrent impacts, in this embodiment, a plurality of fasteners 35 are arranged around the circumference of the dustproof structure 3 to clamp the dustproof member 34, and at the same time enable the first fixing plate 32 and the second fixing plate 33 to be firmly connected to the housing 2.

1 , in some embodiments, the first fixing plate 32 , the dustproof member 34 , and the second fixing plate 33 are sequentially arranged along the first direction X. The first fixing plate 32 includes a body portion 321 and four bending portions 322 arranged on the body portion 321 , the four bending portions 322 are arranged around the outer peripheral edge of the body portion 321 toward the second fixing plate 33 ; the bending portions 322 abut against the second fixing plate 33 .

It should be noted that in the present embodiment, the overall size of the dustproof member 34 is smaller than the overall size of the first fixing plate 32 and the second fixing plate 33. This allows the dustproof member 34 to be clamped between the first fixing plate 32 and the second fixing plate 33. Referring to Figures 6 and 7, a gap 6 is left on the outer periphery between the first fixing plate 32 and the second fixing plate 33 (within the dotted box in Figures 6 and 7), and the guide plate 43 guides water to flow out of the heat dissipation channel 21 and be discharged through the gap 6.

In this way, by providing the bending portion 322 and abutting the bending portion 322 against the second fixing plate 33, it is prevented that the main body 321 and the second fixing plate 33 clamp the dustproof member 34 too tightly, causing the dustproof member 34 to be airtight and affecting the heat dissipation effect of the energy storage device.

In some embodiments, the waterproof structure 4 is fully welded to the housing 2. The main frame 42 can be fully welded to the housing 2. Of course, the waterproof structure 4 and the housing 2 can also be connected in other ways, not limited to welding.

It should be noted that multiple air inlets 12 (see Figure 5) and air outlets 31 can be set as needed. The shapes of the air inlets 12 and the air outlets 31 can be set to circular, rectangular, elliptical, long waist or other shapes. The shapes can be regular or irregular. Multiple air inlets 12 and multiple air outlets 31 can be arranged in a matrix or in other ways as long as they can meet the actual use requirements. No excessive restrictions are made here.

Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the claims of the present invention.
