[0034] See also Figure 1 , Figure 2 and Figure 3 In one embodiment of the present application, an energy storage cabinet 10 includes a cabinet body 100, a flow guiding mechanism 200 and an air extraction mechanism 300. The flow guiding mechanism 200 and the air extraction mechanism 300 are both connected to the cabinet body 100.
[0035] See also Figure 3 , Figure 4 and Figure 5In some embodiments, the cabinet 100 is provided with a housing cavity 110 and an air outlet 120. The housing cavity 110 is used to accommodate the battery module, and the air outlet 120 communicates with the outside and the housing cavity 110. The cabinet 100 may be roughly a rectangular parallelepiped structure, and the cabinet 100 includes a top plate 131, a bottom plate 132, a side frame 133, and a column 134. The bottom plate 132 and the bottom plate 132 may be roughly rectangular plates, and the bottom plate 132 and the top plate 131 are spaced a certain distance apart along the thickness direction of the bottom plate 132. The thickness direction of the bottom plate 132 and the top plate 131 may be the same as the extension direction of the column 134. The top plate 131 is connected to one end of the side frame 133 and closes one end opening of the side frame 133, and the bottom plate 132 is connected to the other end of the side frame 133 and closes the other end opening of the side frame 133. Therefore, the side frame 133 is connected between the top plate 131 and the bottom plate 132, and the top plate 131, the bottom plate 132 and the side frame 133 together enclose the accommodating cavity 110. One end of the column 134 is connected to the top plate 131, and the other end of the column 134 is connected to the bottom plate 132, so that the column 134 is connected between the top plate 131 and the bottom plate 132. The number of the columns 134 can be multiple, and the multiple columns 134 can be arranged at intervals along the extension direction perpendicular to the columns 134.
[0036] In some embodiments, the guide mechanism 200 is fixed in the accommodating cavity 110, and the guide mechanism 200 is provided with a guide channel 211, which extends in the direction of the column 134 and is linear. The guide channel 211 connects the accommodating cavity 110 and the air outlet 120. The heat generated by the battery module during the charging and discharging process can be first discharged to the accommodating cavity 110, and then concentrated into the accommodating cavity 110 and discharged from the air outlet 120 to the outside of the cabinet 100 and the entire energy storage cabinet 10, so that the heat in the accommodating cavity 110 can be effectively discharged. The cross-section of the guide channel 211 can be polygonal, circular or elliptical, for example, the cross-section of the guide channel 211 can be rectangular or square.
[0037] See also Figure 3 , Figure 4 and Figure 5In some embodiments, the air guide mechanism 200 includes an air guide tube 210, and the air guide tube 210 forms an air guide channel 211, that is, the air guide channel 211 is arranged on the air guide tube 210. The air guide tube 210 is provided with an air inlet 212, and the number of the air inlet 212 is multiple, and the multiple air inlets 212 are arranged along the extension direction of the air guide channel 211 to form at least one row, for example, the air inlets 212 can be arranged along the extension direction of the air guide channel 211 to form two rows. The contour line of the air inlet 212 can be rectangular or circular, etc. The air inlet 212 connects the accommodating cavity 110 and the guide channel 211. The air inlet 212 corresponds to the exhaust port of the battery module, so that the exhaust ports of different battery modules can correspond to different air inlets 212, and the heat generated by different battery modules can be discharged into different air inlets 212 through the exhaust ports. Obviously, the heat in the air inlet 212 will be gathered in the guide channel 211, and the heat gathered in the guide channel 211 will be discharged from the air outlet 120 at the same time, thereby realizing the heat discharge in the accommodating cavity 110.
[0038] See also Figure 4 , Figure 5 and Figure 6 In some embodiments, the guide mechanism 200 further includes a buffer pad 220, which is made of a flexible material, so that the buffer pad 220 has a certain flexibility. The buffer pad 220 is arranged around the air inlet 212 and the exhaust port, and the buffer pad 220 is used to press between the guide tube 210 and the battery module. By providing the buffer pad 220, on the one hand, during the installation process of the guide tube 210, by abutting the buffer pad 220 with the battery module, the installation error of the guide tube 210 can be absorbed, thereby improving the installation accuracy of the guide tube 210. On the other hand, the exhaust port of the battery module and the air inlet 212 of the guide tube 210 can be sealed, thereby reducing the suction force generated by the exhaust mechanism 300 on the accommodating chamber 110, and also preventing the hot air flow in the exhaust port from overflowing into the accommodating chamber 110, ensuring that the hot air flow flows into the guide channel 211 through the air inlet 212 as much as possible and is discharged from the air outlet 120.
[0039] See also Figure 4 , Figure 5 and Figure 6In some embodiments, the flow guide mechanism 200 further includes a positioning member 230, which can be protruded on the outer surface of the flow guide tube 210 along the extension direction perpendicular to the flow guide channel 211. The number of the positioning members 230 can be multiple, and the multiple positioning members 230 are arranged at intervals along the extension direction of the flow guide channel 211. The same buffer pad 220 can correspond to two positioning members 230, so that the buffer pad 220 is sandwiched between the two positioning members 230. On the one hand, the buffer pad 220 is positioned by two positioning members 230, so that the installation accuracy of the buffer pad 220 can be improved. On the other hand, the positioning member 230 can reasonably enhance the rigidity and stability of the flow guide tube 210, and avoid deformation of the flow guide tube 210 when the length is large.
[0040] See also Figure 4 , Figure 5 and Figure 6 In some embodiments, the flow guide mechanism 200 further includes a fixing bracket 240, which can be riveted to the column 134, so as to fix the flow guide mechanism 200 on the cabinet 100, avoiding welding connection between the flow guide mechanism 200 and the cabinet 100, thereby reducing the manufacturing cost of the energy storage cabinet 10. The fixing bracket 240 includes a first fixing portion 241 and a second fixing portion 242, and the number of the second fixing portions 242 is two. The two second fixing portions 242 are respectively connected to the opposite ends of the first fixing portion 241. The first fixing portion 241 extends a certain length along the circumference of the flow guide tube 210 and is fixedly attached to the flow guide tube 210. The first fixing portion 241 can be fixed to the flow guide tube 210 by riveting, so as to reduce the manufacturing cost of the energy storage cabinet 10. The first fixing portion 241 and the second fixing portion 242 are arranged at an angle near the connection between the two, so that it is convenient for the second fixing portion 242 to be fixedly connected to the cabinet 100 by riveting. For example, the second fixing portion 242 may be fixedly connected to the column 134, and the two second fixing portions 242 on the same fixing bracket 240 may be fixedly connected to two adjacent columns 134. In other embodiments, the fixing bracket 240 may be screwed to the column 134.
[0041] In some embodiments, the guide tube 210 includes a first guide section 213 and a second guide section 214. The second guide section 214 is sleeved outside the first guide section 213, and the second guide section 214 can be fixedly connected to the first guide section 213 by riveting. The end of the first guide section 213 away from the second guide section 214 can be fixedly connected to the bottom plate 132 of the cabinet 100, and the end of the second guide section 214 away from the first guide section 213 can be fixedly connected to the top plate 131 of the cabinet 100. Along the extension direction of the guide channel 211 and from the first guide section 213 to the second guide section 214, the cross section of the first guide section 213 remains constant, the cross section size of the second guide section 214 increases, and the air extraction mechanism 300 is at least partially contained in the second guide section 214. The air inlet 212 can be opened on the first guide section 213.
[0042] See also Figure 1 , Figure 2 and Figure 3 In some embodiments, the exhaust mechanism 300 includes a fixed seat 310 and a fan 320. The fixed seat 310 can be fixed on the top plate 131 of the cabinet 100. The fixed seat 310 can be set at the position of the air outlet 120. The fan 320 is set on the fixed seat 310. The fixed seat 310 can serve as a carrier for the fan 320. The fan 320 can be at least partially accommodated in the second guide section 214 of the guide tube 210. When the fan 320 works in the second guide section 214, the fan 320 will generate a suction force, so that the gas in the guide channel 211 is discharged from the air outlet 120 to the outside of the entire energy storage cabinet 10 under the action of the fan 320.
[0043] In some embodiments, the number of the flow guiding mechanism 200 and the air extraction mechanism 300 is multiple and corresponds to each other, so that the number of the flow guiding mechanism 200 and the air extraction mechanism 300 can be equal, and one air extraction mechanism 300 is responsible for extracting air from the flow guiding channel 211 in one flow guiding mechanism 200. The multiple flow guiding mechanisms 200 are arranged at intervals along the extension direction perpendicular to the flow guiding channel 211, for example, the number of the flow guiding mechanism 200 can be two, etc. By providing multiple flow guiding mechanisms 200, the heat generated by the battery module is discharged from the multiple flow guiding channels 211, which can increase the heat discharged from the air outlet 120 of the energy storage cabinet 10 per unit time, thereby improving the heat dissipation effect of the energy storage cabinet 10.
[0044] When the exhaust mechanism 300 is working, the fan 320 rotates, and the heat generated by the battery module enters the guide channel 211 through the exhaust port and the air inlet 212. The fan 320 discharges the hot air in the guide channel 211 from the air outlet 120 to the outside of the entire energy storage cabinet 10. In this way, the heat dissipation of the battery module can be achieved.
[0045] If a fan is set on the battery module and a heat dissipation hole is opened on the cabinet, the fan 320 first discharges the heat in the battery module to the accommodating cavity, and then discharges the heat in the accommodating cavity to the outside of the cabinet through the heat dissipation hole, but the heat dissipation hole cannot discharge the heat generated by the battery module from the accommodating cavity in time. As a result, the temperature in the accommodating cavity gradually increases. Therefore, the fan on the battery module requires greater power, which leads to increased manufacturing costs. If the fan is installed on the cabinet, the fan first discharges the heat in the battery module to the accommodating cavity, and then discharges the heat in the accommodating cavity to the outside of the cabinet through fan suction. This will result in poor heat dissipation effect. If a corresponding heat dissipation channel is set in the cabinet, it will lead to an increase in manufacturing costs.
[0046] As for the energy storage cabinet 10 in the above embodiment, since the heat generated by the battery module enters the guide channel 211 through the exhaust port and the air inlet 212, the fan 320 discharges the hot air flow in the guide channel 211 from the air outlet 120 to the outside of the entire energy storage cabinet 10, thereby achieving heat dissipation of the battery module. In addition, since the guide channel 211 is linear, the flow resistance of the hot air flow in the guide channel 211 can be reduced, and the flow path of the hot air flow can be shortened. In this way, the heat generated by the battery module can be discharged to the outside of the cabinet 100 through the guide channel 211 in a short time, thereby improving the heat dissipation effect of the energy storage cabinet 10 on the battery module. At the same time, the guide mechanism 200 provided with the linear guide channel 211 is relatively simple in structure, thereby reducing the manufacturing cost and assembly cost of the guide mechanism 200, and finally reducing the manufacturing cost of the entire energy storage cabinet 10. Furthermore, since the flow resistance of the hot air flow in the guide channel 211 is reduced, the power of the fan 320 in the exhaust mechanism 300 can also be reasonably reduced, thereby reducing the energy consumption of the energy storage cabinet 10 per unit time, that is, the operating cost of the energy storage cabinet 10 can be reduced.
[0047] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0048] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
