Figure 2 This is another structural schematic diagram of the energy storage battery cabinet provided in the embodiment of the present application. Figure 5 A top view of two adjacent battery clusters provided in an embodiment of the present application.

[0040] like Figure 1 and Figure 2 As shown, an energy storage battery cabinet comprises:

[0041] The cabinet 10 is provided with a cavity;

[0042] At least one battery cluster 20 is disposed in the cavity, and a gap 230 is formed inside the battery cluster 20 to communicate with the outside of the battery cluster 20;

[0043] At least one air flow component 50, installed at least on the first surface 210 of the battery cluster 20;

[0044] A heat exchanger 60, disposed on the inner wall of the cavity and close to the second surface 220 of the battery cluster 20, where the second surface 220 intersects the first surface 210;

[0045] Wherein, the air outlet of the air flow component 50 is communicated with one end of the heat exchanger 60, and the gap 230 is communicated with the other end of the heat exchanger 60.

[0046] In this embodiment, the air flow component 50 can be a fan or a blower. Each battery in the battery cluster 20 can correspond to a fan or a blower. The air outlet of the air flow component 50 is communicated with one end of the heat exchanger 60, so as to ensure that when the air flow component 50 sucks out the heat inside the battery, it can quickly send it to the heat exchanger 60 for heat exchange. At the same time, the other end of the heat exchanger 60 is communicated with the gap 230 and can directly extend into the gap 230. It can not only increase the heat exchange area, but also enhance the heat exchange efficiency, so as to ensure that the heat of each battery in the battery cluster 20 can come into contact with the heat exchanger 60 in time, so that the heat exchanger 60 can timely send the cold air flow through the gap 230 into the inside of the battery cluster 20 to ensure that the battery cluster 20 can quickly perform self-circulation cooling, greatly improving the heat dissipation effect.

[0047] At the same time, the first surface 210 and the second surface 220 can be two adjacent side surfaces of the battery cluster 20 respectively, or the first surface 210 can be an end surface of the battery cluster 20 and the second surface 220 can be a side surface of the battery cluster 20, that is, the plane where the first surface 210 is located can intersect the plane where the second surface 220 is located.

[0048] In addition, the gap 230 referred to in this application can be the gap 230 formed between two battery cells or two battery modules in the battery cluster 20. The surface of the battery cell corresponding to the gap 230 can correspond to the first surface 210, so as to better realize heat exchange.

[0049] The battery energy storage cabinet provided by the present application includes a cabinet body 10, at least one battery cluster 20, at least one air flow component 50, and a heat exchanger 60. The cabinet body 10 is provided with a cavity. The battery cluster 20 is arranged in the cavity, and the battery cluster 20 is provided with a gap 230. The air flow component 50 is arranged on the first surface 210 of the battery cluster 20, and the heat exchanger 60 is arranged on the inner wall of the cavity and close to the second surface 220 of the battery cluster 20. The air outlet of the air flow component 50 is communicated with one end of the heat exchanger 60, and the gap 230 is communicated with the other end of the heat exchanger 60. Thus, the air flow component 50 can timely send the heat inside the battery into the heat exchanger 60, and after being cooled by the heat exchanger 60, it is sent into the battery through the gap 230 of the battery cluster 20 to perform self-circulation cooling on the battery, which not only meets the heat dissipation requirements of the batteries in the energy storage battery cabinet, but also can reduce the heat dissipation cost of the energy storage battery cabinet.

[0050] In some embodiments, as Figure 2 、 Figure 3 and Figure 5 shown, the battery cluster 20 includes at least one first battery module 201 and at least one second battery module 202; wherein, the first battery module 201 and the second battery module 202 are arranged along a first direction to form a gap 230 between the first battery module 201 and the second battery module 202.

[0051] In this embodiment, the first direction may be Figure 5 the x direction in

[0052] , that is, the first battery module 201 and the second battery module 202 can be arranged horizontally from left to right. The first battery module 201 and the second battery module 202 can be connected in parallel or in series. A gap 230 mentioned in the present application can be formed between the first battery module 201 and the second battery module 202. Furthermore, the heat exchanger 60 can input the cold flow from the gap 230 to cool the first battery module 201 and the second battery module 202.

[0053] In some embodiments, the number of the air flow components 50 is equal to the sum of the numbers of the first battery modules 201 and the second battery modules 202.

[0054] Specifically, each first battery module 201 and each second battery module 202 can each correspond to an air flow component 50, that is, a fan or a blower, so as to ensure that the heat generated by each battery module can be timely taken away by the air flow component 50, thereby ensuring the balanced heat dissipation of each battery module in the battery cluster 20 and improving the temperature uniformity of each battery in the energy storage battery cabinet. Figure 2 、 Figure 3 and Figure 4, the battery cluster 20 includes a plurality of first battery modules 201 and a plurality of second battery modules 202. The plurality of first battery modules 201 are arranged along a second direction, and the plurality of second battery modules 202 are arranged along the second direction. The second direction is perpendicular to the first direction.

[0055] In this embodiment, the first direction may be Figure 4 the x direction in [[]], that is, the first battery modules 201 and the second battery modules 202 may be arranged from left to right in the horizontal direction. The first battery modules 201 and the second battery modules 202 may be connected in parallel or in series, and a gap 230 mentioned in this application may be formed between the first battery modules 201 and the second battery modules 202; the second direction may be Figure 4 the y direction in [[]], that is, the plurality of first battery modules 201 may be arranged in sequence from bottom to top in the horizontal direction. The plurality of first battery modules 201 may be connected in parallel or in series, the plurality of second battery modules 202 may be arranged in sequence from bottom to top in the horizontal direction, and the plurality of second battery modules 202 may be connected in parallel or in series.

[0056] It can be understood that the plurality of first battery modules 201 mentioned in this application may also be arranged along a third direction, and the plurality of second battery modules 202 may also be arranged along the third direction. The third direction may be Figure 5 the z direction in [[]], that is, the plurality of battery modules may be arranged in sequence from front to back in the horizontal direction.

[0057] In some embodiments, as Figure 5 and Figure 6 shown, the heat of the battery cluster 20 enters the heat exchanger 60 along the third direction. The third direction is perpendicular to the first direction and perpendicular to the second direction.

[0058] In this embodiment, the first direction may be the x direction, that is, the left - right direction, the second direction may be the y direction, that is, the up - down direction, and the third direction may be the z direction, that is, the front - back direction. The heat in the battery cluster 20 can be sucked away by the air flow component 50 installed on the first surface 210, and flows into the heat exchanger 60 installed on the second surface 220 along the third direction, and exchanges heat along the first direction. Finally, the heat exchanger 60 conducts the cold flow to the inside of the battery cluster 20 from the gap 230 to realize the cooling self - circulation process of the battery cluster 20.

[0059] In some embodiments, as Figure 2 and Figure 3 shown, the air flow component 50 is installed on the first surface 210 of the battery cluster 20 through a first mounting member; the heat exchanger 60 is installed on the inner wall of the cavity through a second mounting member.

[0060] Specifically, the air flow assembly 50 can be installed on the first surface 210 of the battery cluster 20 through the first mounting member to be integrated with the battery cluster 20. The heat exchanger 60 can be installed on the inner wall of the cabinet 10 (i.e., the inner wall of the cavity) through the second mounting member to be integrated with the cabinet 10. At the same time, the second mounting member is close to the second surface 220 of the battery cluster 20, so that the heat exchanger 60 can penetrate into the gap 230 of the battery cluster 20 to cool the battery cluster 20.

[0061] In some embodiments, as Figure 2 and Figure 3 shown, the first mounting member includes a plurality of first mounting plates 301. The first mounting plates 301 are arranged on the first surface 210, and the number of the first mounting plates 301 is equal to the sum of the numbers of the first battery modules 201 and the second battery modules 202; the second mounting member includes at least two second mounting plates 302. The second mounting plates 302 are arranged on the inner wall of the cavity and are close to the second surface 220. Each of the first battery module 201 and the second battery module 202 corresponds to at least one second mounting plate 302.

[0062] In this embodiment, the first mounting member includes a plurality of first mounting plates 301, and the second mounting member includes a plurality of second mounting plates 302. Each battery module in the battery cluster 20 corresponds to one first mounting plate 301, and each mounting plate is provided with a fan or a blower. Each column of battery modules in the battery cluster 20 corresponds to one second mounting plate 302, that is, each of the first battery module 201 and the second battery module 202 corresponds to one second mounting plate 302 respectively.

[0063] In some embodiments, a sealing structure is provided between the battery cluster 20 and the inner wall of the cavity. The sealing structure cooperates with the second mounting member to seal the cold flow in at least one gap 230 within the gap 230 corresponding to the cold flow.

[0064] In this embodiment, the cooperation between the sealing structure and the second mounting member can ensure that the gaps between the battery clusters 20 are not communicated with each other, so as to seal the cold flow conducted by the heat exchanger 60 within the gap 230 corresponding to the cold flow, avoid the leakage of the cold flow. Thus, it can not only ensure that the heat exchanger 60 can efficiently cool and dissipate heat inside the battery cluster 20, but also realize the separate cooling and heat dissipation of the inside of each battery cluster 20, avoid the waste of energy, and ensure the balance of the internal temperatures of the battery clusters 20.

[0065] Further, in some embodiments, as Figure 3 、 Figure 4 and Figure 5 shown, the sealing structure includes at least one sealing plate 401; wherein, the sealing plate 401 is arranged between the top of the battery cluster 20 and the top of the cavity.

[0066] In this embodiment, the sealing structure includes a plurality of sealing plates 401. The sealing plates 401 can be disposed between the top of the battery cluster 20 and the top of the cavity. That is, the upper end of the sealing plate 401 can be fixedly connected to the top of the cavity in a sealed manner, and the lower end of the sealing plate 401 can be fixedly connected to the top of the battery cluster 20 in a sealed manner. At the same time, the gap 230 of the battery cluster 20 can be disposed between two sealing plates 401, and the left end and the right end of the sealing plate 401 can be respectively fixedly connected to a second mounting plate 302 in a sealed manner, so as to ensure that the gaps 230 between the battery clusters 20 are not communicated with each other, thereby ensuring that the heat exchanger 60 can efficiently cool and dissipate the heat inside each battery cluster 20, avoiding waste of energy, and ensuring the balance of the internal temperature of each battery cluster 20.

[0067] In some embodiments, the energy storage battery cabinet further includes a control module. Among them, the control module is electrically connected to at least one airflow component 50 and is used to control the airflow speed of the airflow component 50.

[0068] In this embodiment, a control module can also be provided in the energy storage battery cabinet. The control module can be electrically connected to the airflow component 50, so as to control the airflow of the airflow component 50, ensure that the airflow component 50 can timely send out the heat inside the battery cluster 20, and further avoid the temperature inside the battery from being too high, greatly improving the service life of the battery.

[0069] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can easily think of various equivalent modifications or replacements within the technical scope disclosed in the present application, and these modifications or replacements should be covered by the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
