Those skilled in the art will appreciate that the present application can be practiced without certain specific details. In some instances, methods, means, components, and circuits well known to those skilled in the art are not described in detail in order to highlight the main purpose of the present application.

[0034] This application proposes an energy storage converter, such as Figures 1 to 9 As shown, it includes: a cabinet 100, an inverter power unit 200, a power inductor 310, a first heat dissipation assembly 410 and a second heat dissipation assembly; an inductor compartment 320 is provided at the bottom of the cavity of the cabinet 100; the power inductor 310 is arranged in the inductor compartment 320; the first heat dissipation assembly 410, the inverter power unit 200, and the inductor compartment 320 are sequentially arranged inside the cavity of the cabinet 100 from top to bottom; the inverter power unit 200 includes: a first inverter 210 and a second inverter 220 arranged opposite to each other; and the first inverter 210 A preset distance is set between the first heat dissipation component 410 and the second inverter 220 to form a heat dissipation duct 230; the blowing end of the first heat dissipation component 410 is directed toward the heat dissipation duct 230 between the first inverter 210 and the second inverter 220, and the blowing end of the first heat dissipation component 410 is connected to the interior of the cavity of the inductor cabin 320 through the heat dissipation duct 230; the second heat dissipation component is arranged on one side of the first heat dissipation component 410, and the second heat dissipation component is suitable for adsorbing hot air in the cabinet 100, and absorbing the heat of the hot air and cooling it before discharging it back into the cabinet 100.

[0035] It should be noted here that the cabinet 100 provides a stable installation space for the inverter power unit 200, the power inductor 310, the first heat dissipation component 410 and the second heat dissipation component. The inductor compartment 320 provides a relatively independent and closed space for the power inductor 310, effectively avoiding interference and damage from the external environment, and ensuring the normal operation of the inductor element. The radiator of the first inverter 210 and the radiator of the second inverter 220 are arranged relative to each other and are provided with a preset distance to form a heat dissipation channel 230. The heat dissipation channel 230 allows air to flow between the radiator of the first inverter 210 and the radiator in the second inverter 220, thereby taking away the heat generated by the first inverter 210 and the second inverter 220, which helps to reduce the working temperature of the inverter power unit. The operating temperature is reduced to improve the heat dissipation efficiency of the inverter power unit 200. The blowing end of the first heat dissipation component 410 sends cold air into the heat dissipation duct 230. The cold air not only directly cools the first inverter 210 and the second inverter 220, but also flows to the interior of the cavity of the inductor compartment 320 through the heat dissipation duct 230, thereby helping to reduce the temperature of the power inductor 310 in the inductor compartment 320. The second heat dissipation component can continuously adsorb and cool the hot air in the cabinet 100 through a circulating heat dissipation method, and discharge the cooled air back into the cabinet 100. This circulating heat dissipation method helps to maintain the temperature stability in the cabinet 100, reduce the performance degradation and failure rate of the energy storage converter due to overheating, and thus improve the stability of the entire energy storage converter.

[0036] Compared with the prior art, this application Figure 7 As shown, the design of the independent heat dissipation duct 230 enables the first heat dissipation component 410 to directly dissipate heat for the inverter power unit 200 and the power inductor 310, two components with relatively high heat generation. This design can more effectively reduce the temperature of the inverter power unit 200 and the power inductor 310, reduce the loss and interference of heat during the transfer process, and make the heat dissipation process more efficient. Figure 8 As shown, the second heat dissipation component dissipates heat to other components in the cabinet 100 by circulating heat dissipation, ensuring that the overall temperature in the cabinet 100 is maintained within an appropriate range. By setting the first heat dissipation component 410 and the second heat dissipation component, the dual heat dissipation design enables each heat dissipation component to focus on the heat dissipation area it is responsible for, thereby improving the overall heat dissipation efficiency and ensuring that each component operates within an appropriate operating temperature range.

[0037] In one possible implementation, Figure 3 、 Figure 5 、 Figure 7As shown, a wind deflector 211 is provided within the heat dissipation duct 230. The two sides of the wind deflector 211 are connected to the first inverter 210 and the inductor compartment 320, respectively, and are adapted to guide the hot air within the heat dissipation duct 230 into the cavity of the inductor compartment 320. It should be noted that the main body of the wind deflector 211 is a rectangular plate-like structure. One end of the wind deflector 211 is connected to the first inverter 210 and positioned below the heat sink of the first inverter 210. The other end of the wind deflector 211 extends into the cavity of the inductor compartment 320 and is fixedly connected to the inner wall of the inductor compartment 320. The rectangular plate-like structure of the wind deflector 211 effectively guides the cold air to flow toward the inductor compartment 320 in a predetermined direction and path, ensuring that the cold air is evenly distributed to the inductor compartment 320 that needs cooling, thereby improving heat dissipation efficiency.

[0038] In one possible implementation, Figure 3 、 Figure 5 As shown, there are more than two inverter power units 200; the more than two inverter power units 200 are closely arranged along the length of the cabinet 100. It should be noted that one end of the heat dissipation duct 230 formed by the more than two inverter power units 200 is connected to the blowing end of the first heat dissipation assembly 410, and the other end of the heat dissipation duct 230 formed by the more than two inverter power units 200 is connected to the inductor compartment 320. The design of closely arranging the inverter power units 200 along the length of the cabinet 100 can more effectively reduce the space occupied by the cabinet 100 and improve the compactness of the overall structure.

[0039] Further, such as Figure 1 As shown, a fixing beam 110 is provided between each two adjacent inverter power units 200. Both ends of the fixing beam 110 are fixedly connected to the cabinet 100, providing fixed support for the inverter power units 200. Fixing members are provided on both sides of the inverter power units 200. The fixing members on each of the two adjacent inverter power units 200 extend into the grooves of the fixing beam 110. Bolts are sequentially inserted through the fixing members and fixedly connected, thereby installing the inverter power units 200 within the cavity of the cabinet 100 via the fixing beam 110.

[0040] Preferably, three inverter power units 200 are provided, and the first inverter 210 and the second inverter 220 in the inverter power unit 200 are both DC / AC inverters in the prior art.

[0041] In one possible implementation, Figure 4As shown, the first heat dissipation component 410 includes eight centrifugal heat dissipation fans, which are arranged opposite to each other in pairs. The blowing ends of the eight centrifugal heat dissipation fans are all facing the heat dissipation duct 230. The eight centrifugal heat dissipation fans send cold air into the heat dissipation channel 230. The cold air passes through the heat dissipation channel 230 and the inductor cabin 320 in turn and cools the inverter power unit 200 and the power inductor 310 in the inductor cabin 320 before being discharged. The eight centrifugal heat dissipation fans work together to generate a strong airflow, which can quickly take away the heat in the heat dissipation duct 230 and the inductor cabin 320, ensuring that the inverter power unit 200 and the power inductor 310 always operate within a suitable temperature range, thereby improving the heat dissipation efficiency and extending the service life of the equipment.

[0042] In one possible implementation, Figure 2 、 Figure 4 、 Figure 8 As shown, the second heat dissipation component includes an exhaust fan 421, a heat exchanger 422 and a hair dryer 423; the air outlet end of the exhaust fan 421 is connected to the air inlet end of the hair dryer 423 through the heat exchanger 422; and the air inlet end of the exhaust fan 421 and the air outlet end of the hair dryer 423 are both facing one side of the inverter power unit 200.

[0043] It should be noted here that if Figure 2 As shown, the air inlet end of the exhaust fan 421 and the air outlet end of the hair dryer 423 are both facing one side of the inverter power unit 200. The air inlet end of the exhaust fan 421 and the air outlet end of the hair dryer 423 absorb the hot air in the cabinet 100 and discharge cold air. The exhaust fan 421 is suitable for sucking the hot air in the cabinet 100 into the heat exchanger 422. The air outlet end of the exhaust fan 421 is connected to the air inlet end of the heat exchanger 422. The heat exchanger 422 performs heat exchange on the hot air sucked by the exhaust fan 421 to form cold air. The air outlet end of the heat exchanger 422 is connected to the air inlet end of the hair dryer 423. The cold air is sent back to the cavity of the cabinet 100 through the air outlet end of the hair dryer 423. The design of the second heat dissipation component forms a closed-loop heat dissipation system. The closed-loop system reduces heat loss and the influence of the external environment, making the heat dissipation process more efficient, reducing the operating temperature of the components in the cabinet 100, and improving its stability and reliability.

[0044] Further, such as Figure 4 As shown, two second heat dissipation components are provided; the two second heat dissipation components are respectively located on opposite sides of the first heat dissipation component 410; the second heat dissipation components arranged opposite to each other on both sides can reduce the temperature gradient, make the temperature distribution in the cavity of the cabinet 100 more uniform, avoid local overheating in the cavity of the cabinet 100, and improve the overall heat dissipation efficiency.

[0045] In one possible implementation, Figure 1As shown, an air inlet 130 is provided on the outer wall of the cabinet 100, which is suitable for the first heat dissipation component 410 to draw outside air into the heat dissipation duct 230 through the air inlet 130. It should be noted that the air inlet end of the first heat dissipation component 410 is connected to the outside world through the air inlet 130. By aligning the positions of the air inlet 130 and the first heat dissipation component 410, it can be ensured that the first heat dissipation component 410 can directly and efficiently deliver outside air into the heat dissipation duct 230, thereby improving heat dissipation efficiency.

[0046] Furthermore, four air inlets 130 are provided, and the four air inlets 130 are relatively arranged around the outer wall of the cabinet 100. Each of the four air inlets 130 is provided with a louver. The louver design prevents rainwater, dust, and other impurities from directly invading the first heat dissipation assembly 410, reducing the maintenance frequency and failure rate of the first heat dissipation assembly 410, and extending the service life.

[0047] In one possible implementation, Figure 6 As shown, the bottom of the cabinet 100 is provided with an air outlet 140; the air outlet 140 is connected to the inductor compartment 320 and is suitable for discharging the hot air in the cavity of the inductor compartment 320 from the air outlet 140. It should be noted that, as Figure 3 As shown, one end of the inductor cabin 320 is connected to the heat dissipation duct 230 through the air guide plate 211, and the other end of the inductor cabin 320 is connected to the air outlet 140. The cold air blown out by the first heat dissipation component 410 passes through the heat dissipation duct 230 and the inductor cabin 320 in turn and is discharged from the air outlet 140. By setting the air outlet 140, it is ensured that the hot air generated in the inductor cabin 320 can be discharged directly and efficiently through the air outlet 140, thereby avoiding heat accumulation in the inductor cabin 320 and improving the heat dissipation efficiency.

[0048] Furthermore, a dustproof net is provided at the air outlet 140, which matches the air outlet 140. The dustproof net is detachably installed at the air outlet 140 by bolts. The dustproof net effectively prevents dust, debris, etc. from entering the cavity of the inductor cabin 320, while allowing air to be discharged from the inductor cabin 320 through the dustproof net, thereby ensuring the normal operation of the energy storage inverter.

[0049] In one possible implementation, Figure 1 、 Figure 3As shown, the cabinet 100 is provided with a cabinet door 150 for opening or closing the cabinet 100, and the cabinet door 150 corresponds to the position of the inverter power unit 200. It should be noted here that the main body of the cabinet 100 is a rectangular parallelepiped structure, and the cabinet 100 is provided with a cavity with an opening on one side. The cabinet door 150 is arranged at the opening on one side of the cabinet 100 and is located below the air outlet 140. The cabinet door 150 is hinged to the outer wall of the cabinet 100 and is suitable for opening or closing the internal cavity of the cabinet 100. The design of the cabinet door 150 corresponding to the position of the inverter power unit 200 allows maintenance personnel to quickly locate and access the components in the cavity of the cabinet 100, thereby improving maintenance efficiency.

[0050] Further, such as Figure 3 As shown, a gas strut 151 is provided between the cabinet door 150 and the outer wall of the cabinet 100, one end of the gas strut 151 is fixedly connected to the cabinet door 150, and the end of the gas strut 151 away from the cabinet door 150 is connected to the cabinet 100. When the cabinet door 150 needs to be opened, the gas strut 151 provides an upward supporting force for the cabinet door 150, so that the cabinet door 150 can be opened smoothly upward. When the cabinet door 150 is closed, the gas strut 151 will gradually release energy, so that the cabinet door 150 can be closed slowly and smoothly. The gas strut 151 provides a stable supporting force for the cabinet door 150, so that the cabinet door 150 can remain stable during the opening or closing process, avoiding the cabinet door 150 from shaking or suddenly closing due to operating errors or accidental touches by the staff.

[0051] Furthermore, two cabinet doors 150 are provided, and the two cabinet doors 150 are symmetrically arranged on the front and back sides of the cabinet 100 .

[0052] In one possible implementation, Figure 1 、 Figure 3 As shown, the cabinet 100 is provided with a double door 160 for opening or closing the cabinet 100. The double door 160 is hinged to the outer wall of the cabinet 100 and is located below the cabinet door 150. The double door 160 is set in opposite directions. The design of the double door 160 provides a convenient access channel to the interior of the cabinet 100. The staff can easily open any one of the double doors 160 as needed, thereby making it more convenient to install, debug and maintain the equipment under the cabinet 100.

[0053] In one possible implementation, it also includes a DC module, an AC module and a control device 530; the DC module and the AC module are arranged side by side in the cavity of the cabinet 100 and adjacent to the inductor compartment 320, and the control device 530 is arranged on the outer wall of the cabinet 100.

[0054] It should be noted here that if Figure 2As shown, the DC module includes a DC side fuse 511, a DC side frame switch 512 and a DC side lightning arrester 513. The DC side frame switch 512 and the DC side lightning arrester 513 are adjacently arranged below the inverter power unit 200. The DC side frame switch 512 is suitable for controlling the on and off of the DC circuit, and the DC side lightning arrester 513 is suitable for preventing lightning overvoltage and other transient overvoltages from damaging the equipment. The DC side fuse 511 is located below the DC side frame switch 512. The AC module includes an AC side output LC circuit 521, an AC side frame switch 522, and an AC side lightning protection circuit 523. The AC side output LC circuit 521 is suitable for filtering harmonics, noise, etc. in the AC power to improve the quality of the output AC power. The AC side frame switch 522 and the AC side lightning protection circuit 523 are arranged adjacent to each other. The output end of the control device 530 is electrically connected to the DC side frame switch 512, the inverter power unit 200, and the AC side frame switch 522, respectively, and is suitable for controlling the DC side frame switch 512, the inverter power unit 200, and the AC side frame switch 522 and connecting status feedback.

[0055] Further, such as Figure 9 As shown, the DC input ends of two or more inverter power units 200 are electrically connected in parallel, and the DC input ends of the inverter power units 200 are bidirectionally electrically connected to the output ends of the DC side frame switch 512 through DC EMI. The input ends of the DC side frame switch 512 are electrically connected to the positive and negative poles of the battery through the DC side fuse 511. A DC side lightning arrester 513 is provided in series between the DC side fuse 511 and the battery. The AC input ends of the two or more inverter power units 200 are electrically connected in parallel through the AC side output LC circuit 521. The AC side output LC circuit 521 is bidirectionally electrically connected to the output end of the AC side frame switch 522 through AC EMI. The input end of the AC side frame switch 522 is electrically connected to the power grid, and an AC side lightning protection circuit 523 is provided in series between the AC side frame switch 522 and the power grid.
