[0018] The energy storage system control cabin of the present invention can discharge the heat in the electrical cabinet directly to the outside of the cabin through the heat dissipation window on the side wall of the cabin, which can reduce the accumulation of heat in the cabin and is conducive to ensuring the heat dissipation effect.

[0019] Embodiment of the energy storage system control cabin of the present invention: The energy storage system control cabin includes a cabin body and an electrical cabinet arranged in the cabin body. The electrical cabinet is arranged along the side wall of the cabin body. The electrical cabinet is provided with a heat dissipation duct. The outlet of the heat dissipation duct is arranged on the cabinet side wall of the electrical cabinet facing the cabinet side wall. The electrical cabinet is close to the cabinet side wall. The cabinet side wall and the cabinet side wall can be in contact with the cabin side wall or have a small gap. A heat dissipation window is provided on the cabin side wall. The heat dissipation window corresponds to the outlet of the heat dissipation duct so that the heat in the electrical cabinet is discharged from the outlet of the heat dissipation duct to the heat dissipation window and discharged from the cabin outside the heat dissipation window. This can reduce the accumulation of heat in the cabin and facilitate the use of the open area of ​​the heat dissipation window and the outlet of the heat dissipation duct to discharge the heat smoothly, which is beneficial to ensuring the heat dissipation effect. There is no need to set a motor on the cabin body, which is beneficial to reducing power consumption.

[0020] Specifically, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the energy storage system control cabin in this embodiment is used to place the equipment of the control management unit of the liquid flow energy storage system. The energy storage system control cabin includes a cabin body 1, which is a prefabricated cabin. The main body of the cabin body 1 is a cube. The cabin body 1 includes two side doors 10 opposite to each other in the length direction, two side walls of the cabin body 1 opposite to each other in the width direction, and a top wall and a bottom wall opposite to each other in the height direction. The cabin door 10 on one side of the cabin body 1 and the top wall Figure 1 Not shown. Multiple electrical cabinets 2 are arranged in the cabin 1, and each electrical cabinet 2 is installed in the cabin 1. The cabinet of the electrical cabinet 2 is a regular cube with no protruding structure so that two adjacent electrical cabinets 2 can be placed close to each other. There are four electrical cabinets 2, two of which are close to one of the side walls of the cabin 1, and the other two are close to the side wall of the other cabin 1. The electrical cabinet 2 has a front and a back. The front faces of the two corresponding electrical cabinets 2 in the width direction of the cabin 1 face each other, and the backs of the electrical cabinets 2 face the side walls of the cabin 1. A middle passage is formed between the electrical cabinets 2 that are opposite to each other in the width direction of the cabin 1, so that operators can open the door and enter the cabin 1 to operate the electrical cabinets 2.

[0021] The electrical cabinet 2 is provided with a heat dissipation duct, which has an air duct inlet and an air duct outlet 21. The air duct outlet 21 is arranged on the cabinet side wall of the electrical cabinet 2 facing the side wall of the cabin 1. A heat dissipation window 11 is provided on the side wall of the cabin 1. The heat dissipation window 11 corresponds to the air duct outlet 21 so that the heat in the electrical cabinet 2 is discharged from the air duct outlet 21 to the heat dissipation window 11 and discharged from the cabin 1 from the heat dissipation window 11. The heat accumulation in the cabin 1 can be reduced, and the open area of ​​the heat dissipation window 11 and the air duct outlet 21 can be used to smoothly discharge the heat, which is conducive to ensuring the heat dissipation effect.

[0022] The cabinet body of the electrical cabinet 2 has a metal anti-corrosion shell, which is generally 304 stainless steel or anti-corrosion sprayed cold-rolled steel plate. The cabinet body of the electrical cabinet 2 is a cubic structure, with a front side wall, a rear side wall, a left side wall, a right side wall, an upper side wall, and a lower side wall. The front side wall constitutes the front of the electrical cabinet 2, and the cabinet rear side wall 210 constitutes the back of the electrical cabinet 2. The cabinet rear side wall 210 of the electrical cabinet 2 is arranged close to the side wall of the cabin 1, and the air duct outlet 21 is arranged at the top of the cabinet rear side wall 210 of the electrical cabinet 2, and the air duct inlet is arranged at the bottom of the cabinet of the electrical cabinet 2, so that the air flow passes through the electrical cabinet 2 from bottom to top. The air duct outlet 21 faces backward, and the heat dissipation window 11 on the side wall of the cabin 1 corresponds to the air duct outlet 21 front and back. The heat dissipation window 11 is through in the thickness direction of the side wall of the cabin 1, and the upper and lower dimensions of the heat dissipation window 11 are not less than the upper and lower dimensions of the air duct outlet 21. The heat dissipation window 11 is adjacent to the air duct outlet 21, and the distance between the two is very small, so that the hot air flow from the air duct outlet 21 can be directly discharged through the heat dissipation window 11 to prevent the heat from being dissipated to other spaces in the cabin 1. The heat dissipation window 11 is set at the top of the side wall of the cabin 1, the air duct outlet 21 is a rectangular opening, and the heat dissipation window 11 is also a rectangular opening. Since the same side wall of the cabin 1 corresponds to two electrical cabinets 2, in order to avoid a single heat dissipation window 11 affecting the strength of the side wall of the cabin 1, multiple heat dissipation windows 11 are provided along the length direction of the cabin 1, and the distance between two adjacent heat dissipation windows 11 is relatively close, which ensures the structural strength without affecting the heat dissipation.

[0023] The cabinet body of the electrical cabinet 2 is provided with an electrical compartment 202 and an air guide compartment 201 arranged on the upper side of the electrical compartment 202. A partition 25 is provided between the electrical compartment 202 and the air guide compartment 201. The partition 25 serves as a boundary between the electrical compartment 202 and the air guide compartment 201 without isolating the two compartments. The electrical compartment 202 occupies most of the space of the cabinet. An energy storage inverter device 203 and a bidirectional DC converter device 204 are arranged in the electrical compartment 202. The portion of the front side wall of the cabinet of the electrical cabinet 2 used to enclose the electrical compartment forms a cabinet door. The electrical compartment 202 has a first space for installing the energy storage inverter device 203 and a second space for installing the bidirectional DC converter device 204. The first space is the left space in the electrical compartment 202, and the second space is the right space in the electrical compartment 202. The first space is larger than the second space. The cabinet of the electrical cabinet 2 includes two middle pillars arranged at the junction of the first space and the second space. The two middle pillars are arranged front and back, and the upper ends of the middle pillars are connected to the partition 25, and the lower ends are fixedly connected to the lower side wall of the cabinet. The cabinet doors of the electrical cabinet 2 include a first cabinet door 23 corresponding to the first space and a second cabinet door 24 corresponding to the second space. The first cabinet door 23 is a double-door structure, and the second cabinet door 24 is a single-leaf swing door structure. By opening the first cabinet door 23 and the second cabinet door 24 respectively, electrical appliances such as the energy storage inverter device 203 and the bidirectional DC converter device 204 in the electrical cabinet 2 can be operated.

[0024] The heat dissipation duct of the electrical cabinet 2 includes the space in the electrical compartment 202 and the space in the air guide compartment 201. The partition 25 is a horizontal plate body. The partition 25 is provided with a fan installation port that passes through from top to bottom. A heat dissipation fan with a vertical axis is installed at the fan installation port. There are multiple heat dissipation fans arranged in a rectangular array. The heat dissipation fans on the partition 25 include a first heat dissipation fan 28 corresponding to the first space and a second heat dissipation fan 29 corresponding to the second space. There are four first heat dissipation fans 28 and two second heat dissipation fans 29. The heat dissipation fans can draw the hot air in the electrical compartment 202 to the air guide compartment 201. The air guide compartment 201 is open at the rear side and closed at the other sides. The opening of the open side is horizontally facing the rear side, and the opening forms the air duct outlet 21. The air guide compartment 201 that is separately arranged on the top of the cabinet body is used to guide the hot air flow to flow backward, so that the heat dissipation fan can be arranged on the horizontal partition 25, and the heat dissipation fan is arranged vertically, which is convenient for discharging the heat in the electrical compartment 202. In other implementations, a separate air guide compartment may not be provided, and the air duct outlet may be provided on the rear side wall of the electrical cabinet and face backwards, and the heat dissipation fan may be directly installed at the air duct outlet so that the heat dissipation fan exhausts air backwards.

[0025] The air guide compartment 201 is provided with a smooth air guide wall, which is formed by an arc-shaped air guide plate 26. The projection of the arc-shaped air guide plate 26 in the left and right directions is an arc. One end of the arc-shaped air guide plate 26 faces downward and is connected to the partition 25, and the other end faces the horizontal side and extends to the air duct outlet 21. One arc surface of the arc-shaped air guide plate 26 faces forward, and the other arc surface faces backward. The arc-shaped air guide plate 26 is located in the air guide compartment 201. The lower end of the arc-shaped air guide plate 26 is vertically downward and fixedly connected to the front end of the partition 25. Each heat dissipation fan is arranged at the rear side of the lower end of the arc-shaped air guide plate 26. The upper end of the arc-shaped air guide plate 26 faces horizontally backward and is used to form the upper side edge of the air duct outlet 21. The hot air flow discharged by the heat dissipation fan blows upward onto the arc surface of the arc-shaped air guide plate 26, and flows to the air duct outlet 21 under the guidance of the arc-shaped air guide plate 26, which is conducive to reducing wind resistance and avoiding hot air from forming turbulence in the cabinet. In other embodiments, the air guide plate may not be provided. The hot air flow impacts the upper side wall of the air guide compartment upward and then changes direction to flow backward. The air guide plate may also be a straight plate provided at an angle.

[0026] The side walls of the air guide compartment 201 are flush with the side walls of the electrical compartment 202 to ensure the regular cubic structure of the electrical cabinet 2. A partition wall 27 is provided in the air guide compartment 201 for separating the hot air flow discharged by the first heat dissipation fan 28 from that discharged by the second heat dissipation fan 29. The partition wall 27 is vertically arranged to separate the space between the arc-shaped air guide plate 26 and the partition plate 25. This is conducive to ensuring the heat dissipation effect, and is conducive to ensuring that the first heat dissipation fan 28 and the second heat dissipation fan 29 do not work at the same time and the heat dissipation effect is ensured when the energy storage converter device 203 and the bidirectional DC converter device 204 do not work at the same time.

[0027] The bidirectional DC converter device 204 is installed on the left wall of the cabinet of the electrical cabinet 2. The left wall of the cabinet is provided with corresponding columns for the installation of the device. The space above and below the bidirectional DC converter device 204 is conducive to gas flow. The energy storage converter device 203 includes two equipment cabinets, which are arranged side by side on the left and right. The equipment cabinet includes a mounting frame and components installed in the mounting frame. A pulley is provided at the bottom of the mounting frame to facilitate pushing the equipment cabinet into the cabinet of the electrical cabinet 2. After the equipment cabinet enters the cabinet of the electrical cabinet 2, the equipment cabinet can be fixed by connecting bolts. The mounting frame of the equipment cabinet is provided with a space for the hot air flow to flow from bottom to top. A fan can be provided in the equipment cabinet to facilitate sending the heat in the equipment cabinet to the cabinet of the electrical cabinet 2. In other embodiments, the bidirectional DC converter device and the energy storage converter device can also have their own corresponding electrical cabinets respectively, and are not arranged in the same cabinet.

[0028] An inspection port 211 is provided at the bottom of the rear side wall 210 of the electrical cabinet 2, and the inspection port 211 constitutes an air inlet of the heat dissipation duct. The air inlet of the heat dissipation duct is also the inlet of the duct. There is a baffle at the inspection port, and many vents are provided on the baffle to ensure the air intake effect and prevent debris from entering the electrical cabinet. A bracket is provided at the bottom of the cabin 1, and the bracket is fixed on the bottom wall of the cabin 1. The lower side wall of the cabinet of the electrical cabinet 2 is the bottom wall of the cabinet and supported on the bracket. A wiring space for arranging cables is provided in the bracket. The space below the bidirectional DC converter device 204 is provided with an incoming line connection copper busbar and other auxiliary electrical components, and an outgoing line connection copper busbar is provided at the position corresponding to the inspection port 211 on the back of the energy storage converter device 203. The incoming line connection copper busbar is used to connect the incoming line cable, and the outgoing line connection copper busbar is used to connect the outgoing line cable, so as to ensure the electrical connection between the devices and coordinate the control of the devices. The lower side wall of the electrical cabinet 2 is provided with cable holes for corresponding cables to pass through, the first cable hole 212 is for outgoing cables to pass through, and the second cable hole 213 is for incoming cables to pass through, and the first cable hole 212 and the second cable hole 213 respectively constitute an air inlet of the heat dissipation duct. A front airflow structure 22 is provided at the bottom of each door of the electrical cabinet 2, and the front airflow structure 22 includes a plurality of closely distributed holes to form an air inlet. The cold air outside the cabinet of the electrical cabinet 2 enters the cabinet through the front airflow structure 22 at the front of the cabinet, the cable holes at the bottom of the cabinet, and the inspection port 211 at the back of the cabinet. The cold air flows from bottom to top through the heating equipment to cool the equipment to ensure that the equipment works in a suitable temperature range. The hot air gathers at the top of the cabinet and is discharged from the cabinet after being guided by the air guide plate. A heat dissipation window 11 is provided on the upper part of the side wall of the cabin body 1, and an air inlet window 12 is provided on the lower part. The air inlet window 12 corresponds to the inspection port 211, which serves as the exhaust port and the air inlet of the cabin body 1 respectively.

[0029] The control cabin of the energy storage system is arranged outdoors. To prevent rainwater from entering the cabin, a water retaining structure is provided at the heat dissipation window 11 of the cabin body 1. The water retaining structure here is an upper rain shield 13. The upper rain shield 13 covers the heat dissipation window. The upper rain shield 13 has an arc-shaped wall extending smoothly downward along the arc line based on the side wall of the cabin body 1 and two side walls connected to the left and right ends of the arc-shaped wall. The outer side and the inner side of the arc-shaped wall are both arc surfaces. The downward end of the arc-shaped wall is spaced apart from the cabin body side wall in front and behind.
