[0042] The present application provides an energy storage cabinet, such as Figures 1 to 8 As shown, the energy storage cabinet includes a cabinet body, a battery assembly and an air guide assembly 3. The cabinet body is provided with an air inlet 611 and an air outlet 612. The air inlet 611, the air outlet 612 and the air guide assembly 3 are arranged on the same side of the cabinet body in the first direction L1; the air guide assembly 3 encloses a plurality of air guide channels 71, and the plurality of air guide channels 71 are all connected to the air inlet 611, and the angle between two of the plurality of air guide channels 71 is an obtuse angle. The battery assembly is arranged inside the cabinet, and the battery assembly includes multiple battery boxes 2. The multiple battery boxes 2 are arranged at intervals along the second direction L2. Any two adjacent battery boxes 2 among the multiple battery boxes 2 are surrounded by a heat dissipation channel 72, and the heat dissipation channel 72 is connected to at least one of the multiple air guide channels 71. The side of the battery assembly facing away from the air guide assembly 3 in the first direction L1 is surrounded by a first connecting channel 73 with the inner wall of the cabinet, and the top of the battery assembly is surrounded by a second connecting channel 74 with the inner wall of the cabinet. The heat dissipation channel 72 is connected to the second connecting channel 74 through the first connecting channel 73, and the second connecting channel 74 is connected to the air outlet 612. The first direction L1 is perpendicular to the second direction L2.

[0043] In the energy storage cabinet of the present application, the angle between two of the multiple air guide channels 71 is an obtuse angle, which enables at least one air guide channel 71 to guide air toward the upper side of the cabinet, and at least one air guide channel 71 to guide air toward the lower side, so that the cold air flows to the heat dissipation channel 72 located on the upper side and the heat dissipation channel 72 located on the lower side. When the cold air flows through the heat dissipation channel 72, it can exchange heat with the battery box 2, thereby achieving heat dissipation of the battery box 2. After that, the wind converges to the first connecting channel 73. Due to the principle of rising heat flow, the hot air flows to the second connecting channel 74 located at the top and then flows out through the air outlet 612. In this way, the cold air can flow through the battery box 2 located on the upper side and the battery box 2 located on the lower side, and the battery box 2 can fully contact with the cold air to achieve the improvement of the heat dissipation effect of the battery box 2, thereby improving the heat dissipation effect of the energy storage cabinet and ensuring that the battery can work in the optimal temperature range.

[0044] Optionally, a control box for controlling the charging and discharging of the battery box 2 may also be provided inside the cabinet. The control box may be provided with structures such as a circuit board for controlling the charging and discharging of the battery box 2. The control box is a prior art in the field and will not be described in detail here. A heat dissipation channel 72 is also formed between the control box and the battery box 2. When the cold air flows through the heat dissipation channel 72 between the control box and the battery box 2, it can exchange heat with the control box, thereby achieving heat dissipation of the control box.

[0045] In the embodiments of the present application, Figure 1 , Figure 2 and Figure 7 As shown, the cabinet includes a frame 11, a cover 12 and a cabinet door 13. The cover 12 is fixed on the frame 11. The cover 12 has an opening, and the cabinet door 13 can be opened and closed to cover the opening. A connecting channel 76 can be arranged between the battery assembly and the cabinet door 13, so that the cold air can flow to the heat dissipation channel 72 through the air guide channel 71 and the connecting channel 76. A first connecting channel 73 is arranged on the side of the battery assembly and the cover 12 facing away from the cabinet door 13. The cold air is converted into hot air after heat exchange with the battery in the heat dissipation channel 72, and converges to the first connecting channel 73. Due to the principle of rising heat flow, the hot air flows to the second connecting channel 74 located at the top, thereby realizing the rapid discharge of heat flow and improving the heat dissipation efficiency.

[0046] Furthermore, the energy storage cabinet also includes multiple support assemblies, which correspond one-to-one to multiple battery boxes 2; the support assembly includes two support plates, which extend from both sides of the cabinet in the third direction L3 to the inside of the cabinet, and the battery box 2 is supported on the two support plates included in the support assembly corresponding to the battery box 2, thereby fixing the battery box 2.

[0047] like Figure 1 and Figure 7As shown, a mounting assembly 6 is provided on the side of the cabinet door 13 facing away from the inside of the housing 12, and the mounting assembly 6 includes a shell 61 and a connection mechanism 62. The shell 61 is in a rectangular shape, and the connection mechanism 62 is arranged inside the shell 61. The shell 61 is provided with the above-mentioned air inlet 611 and air outlet 612. The energy storage cabinet includes a first fan and a second fan, and the first fan and the second fan are both fixed on the connection mechanism 62. The first fan is located between the air guide assembly 3 and the air inlet 611 to guide the cold air into the air guide channel 71 through the air inlet 611. The second fan is located between the air outlet assembly 4 and the air outlet 612 to guide the hot air inside the cabinet through the air outlet 612.

[0048] Alternatively, if Figure 8 As shown, the connection mechanism 62 includes a first plate member 621 and a second plate member 622. The upper end of the first plate member 621 is connected to the top of the housing 61, and the lower end of the second plate member 622 is connected to the cabinet door 13. The position of the first plate member 621 can cover the air guide channel 71 and the outflow channel 75. The bottom of the first plate member 621 is provided with a first guide hole 6221. One end of the second plate member 622 is connected to the side of the first plate member 621 that is opposite to the air guide channel 71, and the other end of the second plate member 622 is connected to the bottom of the housing 61. The bottom of the housing 61 is provided with a second guide hole 623. In this way, when water accumulates inside the air guide cover 31, the water can enter the space between the first plate member 621 and the second plate member 622 through the first guide hole 6221, and then flow out through the second guide hole 623. At the same time, when the air outlet 612 sucks in rainwater, the rainwater can flow to the first guide hole 6221 through the first air outlet plate 41 and the second air outlet plate 42 in the air outlet assembly 4 described below, and then flow out through the second guide hole 623 .

[0049] In the embodiments of the present application, Figure 5 As shown, the wind guide assembly 3 includes a wind guide cover 31 and a plurality of wind guide plates 32. The wind guide cover 31 is in a rectangular parallelepiped shape. The wind guide plates 32 are arranged inside the wind guide cover 31, and the wind guide plates 32 can be riveted to the wind guide cover 31 by rivets 33. An air guide channel 71 is enclosed between two adjacent wind guide plates 32. The plurality of wind guide covers 31 can be divided into a plurality of groups. The wind guide plates 32 in each group are parallel. The two adjacent wind guide plates 32 in each group enclose an air guide channel 71. In two groups of wind guide plates 32 in the plurality of groups of wind guide plates 32, the angle between the wind guide plates 32 in one group and the wind guide plates 32 in the other group is an obtuse angle, that is, at least one group of guide plates is tilted upward, and the other group of guide plates 32 is tilted downward, thereby forming at least one wind guide channel 71 for guiding wind upward and at least one wind guide channel 71 for guiding wind downward.

[0050] Preferably, the air guide plates 32 can be divided into two groups, one group of air guide plates 32 is tilted upward, and the other group of air guide plates 32 is tilted downward, so as to form a group of air guide channels 71 tilted upward and a group of air guide channels 71 tilted downward, and a horizontal air guide channel 71 is formed between the two groups of air guide plates 32, and each of the air guide plates 32 tilted downward is correspondingly provided with a connecting plate 34, and the connecting plate 34 is perpendicular to the second direction L2, and two adjacent connecting plates 34 surround a horizontal channel, which can facilitate the cold air to enter the downward-tilted air guide channel 71. In this way, the air guide channel 71 formed by the air guide assembly 3 can guide the cold air to the upper area, the lower area and the middle area, and the cold air flows through the heat dissipation channel 72 between the battery boxes to cool the battery box 2. After that, the hot air flows out through the first connecting channel 73, the second connecting channel 74, the outflow channel 75 and the air outlet 612, so as to achieve the cooling of the battery box 2 or the control box.

[0051] Optionally, the number of air guide plates 32 can be selected according to demand, and the number of groups of air guide plates 32 is not limited to two groups. For example, the air guide plates 32 can be set to three groups, four groups or more groups, at least one group is tilted upward, at least one group is tilted downward, and the angle between the upward tilted and downward tilted guide plates is an obtuse angle to ensure that upward tilted and downward tilted air guide channels 71 can be formed.

[0052] In the embodiments of the present application, Figure 3 and Figure 4 As shown, the energy storage cabinet also includes an air outlet component 4, and an outflow channel 75 is arranged around the top of the air outlet component 4 and the cover shell 12. The two ends of the outflow channel 75 are respectively connected to the air outlet 612 and the second connecting channel 74, so that the wind flowing out of the second connecting channel 74 can flow to the air outlet 612 through the outflow channel 75, and thus be discharged from the interior of the energy storage cabinet.

[0053] Furthermore, if Figure 4 As shown, the air outlet assembly 4 includes a first air outlet plate 41 and a second air outlet plate 42, the first air guide plate 32, the second air guide plate 32 and the housing 12 surround an outflow channel 75, the first air outlet plate 41 is fixed on the frame 11, and the first air outlet plate 41 is perpendicular to the second direction L2, and the first air outlet plate 41 is located above the air guide cover 31 of the air guide assembly 3. The second air outlet plate 42 is arranged obliquely, the lower end of the second air outlet plate 42 is connected to the first air outlet plate 41, and the upper end of the second air outlet plate 42 abuts against the heat dissipation box located at the top, so as to connect the second connecting channel 74 and the outflow channel 75.

[0054] In addition, the energy storage cabinet further includes two wind shields 43, one end of the wind shield 43 in the first direction L1 is connected to the second air outlet plate 42, and the other end of the wind shield 43 in the first direction L1 is connected to the inner wall of the cabinet, and the battery box 2 at the top is respectively attached to the two wind shields 43 on both sides in the third direction L3. In this way, the wind in the second connecting channel 74 can be prevented from being lost to both sides.

[0055] In the embodiments of the present application, Figure 6 and Figure 7 As shown, the energy storage cabinet also includes an adjusting member 5, which is fixed on the side of the cabinet door 13 facing the battery assembly. The adjusting member 5 is located on the air guide assembly 3 located on the lower side of the cabinet. At least a portion of the adjusting member 5 protrudes toward the battery assembly relative to the air guide assembly 3. The size of the connecting channel 76 corresponding to the protruding portion of the adjusting member 5 is smaller than the size of other positions of the connecting channel 76. When cold air flows through the connecting channel 76 corresponding to the protruding portion of the adjusting member 5, the wind speed of the cold air is increased, which can facilitate the cold air to be delivered to the bottom of the cabinet to cool the battery box 2 located on the lower side.

[0056] like Figure 7 As shown, the adjusting member 5 includes a main body 51 and a protruding portion 52, the protruding portion 52 protrudes from the main body 51 toward the battery assembly, and the protruding portion 52 includes a first surface 521, a second surface 522 and a third surface 523 connected in sequence, and the first surface 521 and the third surface 523 are both connected to the main body 51; the first surface 521 is inclined downward, and the second surface 522 is inclined upward, and the distance between the first surface 521 and the third surface 523 is gradually reduced in the direction from the main body 51 to the protruding portion 52. The first surface 521 is inclined, and the cold air flowing out of the downwardly inclined air guide channel 71 can be guided to the lower part of the cabinet to achieve cooling of the battery box 2 located at the lower part.

[0058] The air guide channel 71 formed by the air guide assembly 3 of the present application can guide the cold air to the upper area, the lower area and the middle area, and the cold air can flow through the upper, middle and lower heat dissipation channels 72, ensuring the heat dissipation effect of each battery box 2.
