Description

[0002] Large equipment such as ship unloaders, ship loaders, and stacker-reclaimers are used for loading, unloading, and stacking materials such as coal and iron ore. The operating environment is dusty, and the coastal and riverside environments are humid. From the perspective of dust and moisture prevention, the electrical rooms of the above-mentioned large equipment are enclosed structures, and the heat dissipated by the frequency converter system can be cooled by the air conditioning system.

[0003] The inverter cabinets used in these large pieces of equipment are located in the electrical room, and they have very high power and generate a lot of heat during operation. The cold air from the air conditioner enters the inverter cabinet from the bottom. With the help of the fan in the inverter cabinet, the cold air flows from bottom to top and neutralizes the heat generated by the inverter cabinet. The resulting hot air flows out from the top of the inverter cabinet, and the hot air comes into contact with the cold air from the air conditioner. In order to keep the temperature in the electrical room within a suitable range, more air conditioners are needed to cool it down. Typically, six 5P ceiling-mounted air conditioners and one 10P cabinet air conditioner are used.

[0022] Preferably, the baffle assembly includes an H-shaped baffle;

When the H-shaped baffle is in the open state, the top of its horizontal plate abuts against the upper end of the exhaust vent, and when it is in the closed state, the bottom of its horizontal plate abuts against the lower end of the exhaust vent.

[0024] The up-down drive assembly includes an up-down telescopic assembly, and its movable end is connected to the upper end of the vertical plate of the H-shaped baffle.

[0025] The upper end of the air guide shroud assembly is connected to the upper end of the corresponding vertical plate of the H-shaped baffle.

Detailed Implementation

[0048] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0049] The electrical room provided in this embodiment of the utility model, such as Figure 1 and Figure 2 As shown, it includes at least: an electrical room 6 and a frequency converter cabinet 7 and an air conditioner 5 installed within the electrical room 6, wherein the air conditioner 5 is a ceiling-mounted air conditioner, and the electrical room may also include a floor-standing air conditioner 9; as Figure 3 As shown, the electrical room 6 is provided with an exhaust vent 61, and the electrical room also includes a ventilation and heat dissipation device;

[0050] like Figure 2 As shown, the ventilation and heat dissipation device includes: an exhaust vent opening and closing mechanism, an air guide assembly, and a controller 1;

[0051] The exhaust vent opening and closing mechanism is provided at the exhaust vent 61 of the electrical room 6, and opens the exhaust vent 61 of the electrical room 6 when it is opened, and closes the exhaust vent 61 of the electrical room 6 when it is closed.

[0052] The air guide assembly is installed inside the electrical room 6 and is used to guide the hot air generated by the frequency converter cabinet 7 to the exhaust port 61 of the electrical room 6.

[0053] Controller 1 is used to control the opening and closing of the exhaust port opening and closing mechanism according to the start and stop of the frequency converter cabinet 7.

[0054] It should be noted that the top of the inverter cabinet 7 has an air outlet for discharging hot air, and the exhaust vent 61 of the electrical room 6 can be distributed adjacent to the air outlet on the top of the inverter cabinet 7. This facilitates the air guiding assembly to direct the hot air generated by the inverter cabinet 7 to the exhaust vent 61 of the electrical room 6, thus preventing the hot air generated by the inverter cabinet 7 from coming into contact with the cold air from the air conditioner. Of course, when the exhaust vent opening and closing mechanism is open, the hot air generated by the inverter cabinet 7 can then be discharged outside the electrical room through the exhaust vent 61. The air guiding assembly can be an air guide shroud assembly or a flow guide shroud assembly, as detailed below.

[0055] An exhaust vent opening and closing mechanism is installed at the exhaust vent 61 of the electrical room 6 to control the opening and closing of the exhaust vent 61 of the electrical room 6. The exhaust vent opening and closing mechanism can be installed inside the exhaust vent 61 of the electrical room 6 and can be opened and closed by a flip design. Alternatively, the exhaust vent opening and closing mechanism can be installed on the end face of the exhaust vent 61 of the electrical room 6 and can be opened and closed by a sliding design. For details, please refer to the description below.

[0056] Controller 1 can be installed inside the electrical room 6 and is used to communicate with the frequency converter cabinet 7 and the exhaust vent opening and closing mechanism respectively. It can control the opening and closing of the exhaust vent opening and closing mechanism according to the start and stop of the frequency converter cabinet 7. Specifically, controller 1 can receive the start and stop signals of the frequency converter cabinet 7 and control the opening and closing of the exhaust vent opening and closing mechanism according to the start and stop signals of the frequency converter cabinet 7. That is, when controller 1 receives the start signal of the frequency converter cabinet 7, it sends an open command to the exhaust vent opening and closing mechanism, at which time the exhaust vent opening and closing mechanism opens the exhaust vent 61. When controller 1 receives the stop signal of the frequency converter cabinet 7, it sends a close command to the exhaust vent opening and closing mechanism, at which time the exhaust vent opening and closing mechanism closes the exhaust vent 61. In addition, controller 1 can be a programmable logic controller (PLC), a microcontroller, or an industrial computer (IPC).

[0057] More specifically, when the inverter cabinet 7 starts up, the controller 1 can control the exhaust vent opening and closing mechanism to open based on feedback, such as... Figure 3 As shown, the hot air generated by the inverter cabinet 7 is guided by the air guide assembly to the exhaust vent 61 of the electrical room 6, and then discharged outside the electrical room through the exhaust vent 61. This guides most of the hot air generated by the inverter cabinet 7 out of the electrical room, avoiding convection or contact between the hot air generated by the inverter cabinet 7 and the cold air from the air conditioner. This helps reduce the number of air conditioners in the electrical room, reducing energy consumption, lowering costs, and making the environment more environmentally friendly. The fan inside the inverter cabinet 7 provides the gas delivery power for the hot air exhaust; that is, most of the heat can be directly discharged outside the electrical room through the fan inside the inverter cabinet 7, allowing most of the hot air to be quickly discharged, while only a small portion of the heat needs to be neutralized and cooled by the air conditioner. At the same time, the pressure inside the electrical room is higher than outside, preventing dust from entering the room. Furthermore, when the inverter cabinet 7 stops operating, the controller 1 can control the exhaust vent opening and closing mechanism to close based on feedback. Figure 2 As shown, this closes the exhaust vent 61 of the electrical room body 6, thereby ensuring the airtightness of the electrical room.

[0058] In other words, this solution provides a large equipment electrical room equipped with an automatic ventilation and heat dissipation device. When the inverter cabinet 7 starts, the controller can control the exhaust vent opening and closing mechanism to open according to feedback, so that the exhaust vent 61 of the electrical room body 6 opens. At this time, the hot air generated by the inverter cabinet 7 can be guided to the exhaust vent 61 of the electrical room body 6 through the air guide component, and then discharged outside the electrical room through the exhaust vent 61 of the electrical room body 6. This can guide the hot air (most of the hot air) generated by the inverter cabinet 7 to be discharged outside the electrical room, avoiding convection or contact with the cold air of the air conditioner. This can help reduce the number and power of the air conditioners in the electrical room, reduce energy consumption, reduce costs, and make it more environmentally friendly. Moreover, when the inverter cabinet 7 stops, the controller can control the exhaust vent opening and closing mechanism to close according to feedback, so that the exhaust vent 61 of the electrical room body 6 closes, thereby ensuring the airtightness of the electrical room.

[0059] In this plan, such as Figure 2 As shown, the exhaust vent opening and closing mechanism includes: a baffle assembly 3 and a drive assembly;

[0060] The baffle assembly 3 can open and close the exhaust vent 61 of the electrical room 6, and when it is opened, the exhaust vent 61 of the electrical room 6 is open, and when it is closed, the exhaust vent 61 of the electrical room 6 is closed.

[0061] The drive component is used to drive the opening and closing of the baffle assembly 3;

[0062] Controller 1 is used to control the operation of the drive components according to the start and stop of the frequency converter cabinet 7.

[0063] It should be noted that the baffle assembly 3 is rotatably and openably disposed within the exhaust vent 61 of the electrical room 6. When open, it can be parallel to the axis of the exhaust vent 61 to open the exhaust vent 61 of the electrical room 6. When closed, it can be perpendicular to the axis of the exhaust vent 61 to block the exhaust vent 61 of the electrical room 6. In this case, the drive assembly can be used to drive the rotatable opening and closing of the baffle assembly 3. Alternatively, the baffle assembly 3 can also be slidably and openably disposed on the end face of the exhaust vent 61 of the electrical room 6. When open, it opens the exhaust vent 61 of the electrical room 6, and when closed, it closes the exhaust vent 61 of the electrical room 6. In this case, the drive assembly can be used to drive the sliding opening and closing of the baffle assembly 3. Details are described below; Controller 1. The controller 1 can control the operation of the drive component according to the start / stop signals of the inverter cabinet 7. That is, when the controller 1 receives the start signal of the inverter cabinet 7, it can send an open command to the drive component. The drive component, based on this open command, drives the baffle assembly 3 to open, thereby opening the exhaust vent 61 of the electrical room 6. When the controller 1 receives the stop signal of the inverter cabinet 7, it can send a close command to the drive component. The drive component, based on this close command, drives the baffle assembly 3 to close, thereby closing the exhaust vent 61 of the electrical room 6. Of course, the exhaust vent 61 of the electrical room 6 can be a square exhaust vent, and the baffle assembly 3 can be a corresponding square baffle assembly, thereby ensuring that the exhaust vent 61 of the electrical room 6 can be closed. In other words, the exhaust vent opening and closing mechanism includes two parts: the exhaust vent opening and closing body and the opening and closing drive assembly. This makes the structure of the exhaust vent opening and closing mechanism clear and also makes the opening and closing design of the exhaust vent opening and closing mechanism more reliable.

[0064] Specifically, such as Figure 2 As shown, the inverter cabinet 7 is distributed next to the first wall 62 of the electrical room body 6, and the hot air generated by it is discharged through the air outlet at the top.

[0065] like Figure 3 As shown, the exhaust vents 61 are located on the first wall 62 of the electrical room 6 and are higher than the exhaust vents of the inverter cabinet 7.

[0066] The baffle assembly 3 is installed at the exhaust vent 61 of the electrical room body 6, which can be opened and closed vertically. Moving it upward is the open state, and moving it downward is the closed state.

[0067] The driving component is an up-and-down driving component, and its movable end is connected to the upper end of the baffle component 3;

[0068] like Figure 3 As shown, the air guide assembly includes an air guide shroud assembly 4;

[0069] The upper end of the air guide shroud assembly 4 is connected to the upper end of the baffle assembly 3, and the lower end is connected to the top of the frequency converter cabinet 7. It is used to cover the exhaust port 61 of the electrical room body 6 and the air outlet of the frequency converter cabinet 7.

[0070] It should be noted that the exhaust vent 61 of the electrical room 6 is adjacent to the air outlet at the top of the baffle assembly 3, and is located above and to the side of the air outlet at the top of the baffle assembly 3; the baffle assembly 3 is vertically movable and openable on the end face of the exhaust vent 61 of the electrical room 6, and can move upward to the open state and downward to the closed state; the vertical drive assembly can be installed on the first wall 62 of the electrical room 6, and is located above the baffle assembly 3, and its movable end (which can be the lower end) is connected to the upper end of the baffle assembly 3, for driving the baffle assembly 3 to move up and down, so as to realize the opening and closing of the baffle assembly 3; Figure 3 As shown, the upper end of the air guide shroud assembly 4 is connected to the upper end of the baffle assembly 3, and the lower end can be connected to the first edge of the top of the inverter cabinet 7. It is used to cover the exhaust vent 61 of the electrical room 6 and the air outlet of the inverter cabinet 7, so that the hot air generated by the inverter cabinet 7 is guided to the exhaust vent 61 of the electrical room 6 under the action of the air guide shroud assembly 4; wherein, as... Figure 3 As shown, the longitudinal cross-sectional shape of the air guide shroud assembly 4 can be a quarter-circle arc. Furthermore, to ensure complete coverage of the exhaust vent 61 of the electrical room 6 and the air outlet of the inverter cabinet 7, and to prevent the hot air generated by the inverter cabinet 7 from overflowing and forming convection or contact with the cold air from the air conditioner, the front end (or left end) of the air guide shroud assembly 4 can be connected to the front edge (or left edge) of the top of the inverter cabinet 7 and maintain contact with the first wall 62. The rear end (or right end) of the air guide shroud assembly 4 can be connected to the rear edge (or right edge) of the top of the inverter cabinet 7 and maintain contact with the first wall 62. The wall 62 remains in contact, so that the exhaust vent 61 of the electrical room 6 and the air outlet of the inverter cabinet 7 are completely covered within the air guide shroud assembly 4. Of course, the upper end of the air guide shroud assembly 4 can move up and down with the upper end of the baffle assembly 3, so the air guide shroud assembly 4 needs to be able to extend and retract to ensure that the upper end of the air guide shroud assembly 4 is movable. In addition, if there is enough space inside the air guide shroud assembly 4, the baffle assembly 3 and the drive assembly can also be set inside the air guide shroud assembly 4, so that the upper end of the air guide shroud assembly 4 can be fixedly connected to the first wall 62.

[0071] In other words, the exhaust vent 61 of the electrical room 6 is located above and to the side of the air outlet at the top of the inverter cabinet 7, which facilitates the formation of a protective cover for the exhaust vent 61 of the electrical room 6 and the air outlet of the inverter cabinet 7 through the air guide shroud assembly 4. On the one hand, this guides the hot air generated by the inverter cabinet 7 to the exhaust vent 61 of the electrical room 6, and on the other hand, it prevents the hot air generated by the inverter cabinet 7 from overflowing and convection or contact with the cold air of the air conditioner. Moreover, the upper end of the air guide shroud assembly 4 is connected to the upper end of the baffle assembly 3 and can move up and down with the upper end of the baffle assembly 3, so as to avoid interference from the upper end of the baffle assembly 3. This also ensures that the exhaust vent 61 of the electrical room 6 and the air outlet of the inverter cabinet 7 are always covered within the air guide shroud assembly 4.

[0072] Furthermore, such as Figure 4As shown, the baffle assembly 3 includes an H-shaped baffle 31;

[0073] The two vertical plates of the H-shaped baffle 31 are located on the inner and outer end walls of the exhaust vent 61 of the electrical room body 6, respectively. Figure 5 As shown, when the H-shaped baffle 31 is in the open state, the top of its horizontal plate abuts against the upper end of the exhaust port 61, as... Figure 4 As shown, when closed, the bottom of its horizontal plate abuts against the lower end of the exhaust port 61;

[0074] The up-down drive assembly includes an up-down telescopic assembly, and its movable end is connected to the upper end of the H-shaped baffle 31, a vertical plate.

[0075] The upper end of the air guide shroud assembly 4 is connected to the upper end of the corresponding vertical plate of the H-shaped baffle 31.

[0076] It should be noted that the two vertical plates of the H-shaped baffle 31 are located on the inner end wall (inner end face) and outer end wall (outer end face) of the exhaust vent 61 of the electrical room 6, respectively, and can move up and down (slide up and down) along the inner and outer end walls of the exhaust vent 61 of the electrical room 6 to realize the opening and closing of the H-shaped baffle 31. Furthermore, the way the two vertical plates of the H-shaped baffle 31 are clamped onto the inner and outer end walls of the exhaust vent 61 of the electrical room 6 can prevent the baffle assembly 3 from easily falling off the exhaust vent 61. When the H-shaped baffle 31 is open, the top of its horizontal plate abuts against the upper end of the exhaust vent 61; when it is closed, the bottom of its horizontal plate abuts against the lower end of the exhaust vent 61. This can limit the opening and closing states of the baffle assembly 3, thus achieving upper and lower limit (opening and closing limit) of the baffle assembly 3. To further prevent the baffle assembly 3 from falling off the exhaust vent 61 of the electrical room 6, such as... Figure 4 As shown, the horizontal plate of the H-shaped baffle 31 is distributed between the lower parts of the two vertical plates, that is, it is distributed slightly lower. Moreover, as mentioned above, the exhaust port 61 can be a square exhaust port, and the two vertical plates of the H-shaped baffle 31 can be square vertical plates respectively. In order to ensure the structural strength of the H-shaped baffle 31, the H-shaped baffle 31 can be a metal part, and can be obtained by welding two vertical metal plates and a horizontal metal plate together.

[0077] Furthermore, the vertical telescopic assembly can be installed on the inner wall of the first wall 62, and its movable end (which can be the lower end) is connected to the upper end of the first vertical plate of the H-shaped baffle 31. The upper end of the air guide shroud assembly 4 is also connected to the upper end of the first vertical plate of the H-shaped baffle 31. Alternatively, the vertical telescopic assembly can be installed on the outer wall of the first wall 62, and its movable end (which can be the lower end) can be connected to the upper end of the second vertical plate of the H-shaped baffle 31. The upper end of the air guide shroud assembly 4 can also be connected to the upper telescopic assembly. The movable end of the component is connected; wherein, the first vertical plate of the H-shaped baffle 31 is the vertical plate of the H-shaped baffle 31 located on the inner end wall of the exhaust vent 61 of the electrical room body 6, and the second vertical plate is the vertical plate of the H-shaped baffle 31 located on the outer end wall of the exhaust vent 61 of the electrical room body 6; in addition, in order to ensure that the H-shaped baffle 31 moves smoothly and reliably up and down, a guide structure for the H-shaped baffle 31, such as a guide rail structure, can be provided on the inner end wall and the outer end wall of the exhaust vent 61 of the electrical room body 6, which will not be described in detail here.

[0078] In other words, the baffle assembly 3 is designed in such a way that it can be clamped onto the inner and outer end walls of the exhaust vent 61 of the electrical room 6, which can prevent the baffle assembly 3 from easily falling off the exhaust vent 61 of the electrical room 6, and can also facilitate the opening and closing of the exhaust vent 61 of the electrical room 6. Of course, the baffle assembly 3 can also adopt a single-sided baffle structure and can be moved up and down on the inner end wall of the exhaust vent 61 of the electrical room 6, which will not be elaborated here.

[0079] Furthermore, such as Figure 5 As shown, a U-shaped rubber 32 is provided between the top of the horizontal plate of the H-shaped baffle 31 and the two vertical plates, and the inner wall of the U-shaped rubber 32 abuts against the upper end of the exhaust port 61 when it is open.

[0080] like Figure 4 As shown, an inverted U-shaped rubber 33 is provided between the bottom of the horizontal plate of the H-shaped baffle 31 and the two vertical plates, and the inner wall of the inverted U-shaped rubber 33 abuts against the lower end of the exhaust port 61 when the baffle is closed.

[0081] like Figure 4 As shown, the inner walls of the upper part of the two vertical plates of the H-shaped baffle 31 are provided with rubber 34, which are used to abut against the inner and outer end walls of the upper part of the exhaust port 61.

[0082] It should be noted that the baffle assembly also includes the aforementioned U-shaped rubber 32, inverted U-shaped rubber 33, and two rubbers 34 (vertical rubbers); among which, as shown... Figure 5 As shown, the U-shaped rubber 32 is set on the top of the horizontal plate of the H-shaped baffle 31 and contacts the two vertical plates of the H-shaped baffle 31. When the H-shaped baffle 31 is in the open state, the inner groove of the U-shaped rubber 32 abuts against the upper end of the exhaust port 61, which can play the role of opening buffer.

[0083] like Figure 4 As shown, the inverted U-shaped rubber 33 is set at the bottom of the horizontal plate of the H-shaped baffle 31 and contacts the two vertical plates of the H-shaped baffle 31. When the H-shaped baffle 31 is closed, the inner groove of the inverted U-shaped rubber 33 abuts against the lower end of the exhaust port 61, which not only plays the role of closing buffer, but also ensures the sealing of the exhaust port 61 when it is closed.

[0084] like Figure 4 As shown, the inner sidewalls of the upper part of the two vertical plates of the H-shaped baffle 31 are provided with rubber 34, which are used to abut against the inner and outer end walls of the upper end of the exhaust port 61. This not only ensures the sealing of the exhaust port 61 when it is closed, but also ensures the sealing of the two vertical plates of the H-shaped baffle 31 with the inner and outer end walls of the exhaust port 61 of the electrical room body 6, respectively. This ensures that the required protection level is achieved when the exhaust port 61 is closed, and prevents debris or dust from falling between the H-shaped baffle 31 and the end wall of the exhaust port 61 of the electrical room body 6.

[0085] In other words, the H-shaped baffle 31 is provided with corresponding rubber at multiple specific locations, which can not only play a role in limiting and buffering, but also achieve the sealing of the inner and outer end walls of the H-shaped baffle 31 and the exhaust port 61, and also make the H-shaped baffle 31 wear-resistant.

[0086] In this plan, such as Figure 2 As shown, the up-and-down drive assembly includes a hydraulic telescopic rod 2;

[0087] The hydraulic telescopic rod 2 is vertically mounted downwards on the inner side wall of the first wall 62, and its movable end is connected to the upper end of the corresponding vertical plate of the H-shaped baffle 31. The lower end of the hydraulic telescopic rod 2 serves as its movable end and is connected to the first vertical plate of the H-shaped baffle 31, used to drive the H-shaped baffle 31 to move up and down (slide up and down). The hydraulic telescopic rod 2 is positioned on the upper side of the air guide shroud assembly, facilitating its maintenance and repair. The up-and-down drive assembly uses the hydraulic telescopic rod 2, which features a simple structure and convenient operation. Alternatively, a cylinder can be used, but this will not be elaborated upon here. Furthermore, the upper end of the air guide shroud assembly can be connected to the upper end of the H-shaped baffle 31 and also to the lower end of the hydraulic telescopic rod 2.

[0088] Specifically, such as Figure 2 and Figure 3 As shown, the air guide shroud assembly 4 is extendable and retractable, and its upper end can move up and down with the upper end of the baffle assembly 3. In other words, the air guide shroud assembly 4 is telescopic so that its upper end can move up and down with the upper end of the baffle assembly 3, preventing the air guide shroud assembly 4 from being stretched and deformed, and ensuring the durability of the air guide shroud assembly 4.

[0089] Furthermore, such as Figure 2As shown, the air guide shroud assembly 4 includes: a first rigid air guide shroud 41, a flexible air guide shroud 42, and a second rigid air guide shroud 43;

[0090] The upper end of the first rigid air guide shroud 41 is connected to the upper end of the baffle assembly 3, and the lower end is connected to the upper end of the flexible air guide shroud 42.

[0091] The upper end of the second rigid air guide shroud 43 is connected to the lower end of the flexible air guide shroud 42, and the lower end is connected to the top of the inverter cabinet 7; wherein, the flexible air guide shroud 42 can be extended and retracted.

[0092] It should be noted that, as mentioned above, the longitudinal cross-sectional shape of the air guide shroud assembly 4 can be a quarter-circle arc, and the arcs corresponding to the first rigid air guide shroud 41, the flexible air guide shroud 42, and the second rigid air guide shroud 43 can all be 30°; wherein, the upper end of the first rigid air guide shroud 41 can be connected to the upper end of the first vertical plate of the H-shaped baffle 31 through a bolt assembly, and the lower end of the second rigid air guide shroud 43 can be connected to the first edge of the top of the inverter cabinet 7 through a bolt assembly, so that the exhaust vent 61 of the electrical room 6 and the air outlet of the inverter cabinet 7 are covered by these three air guide shrouds, such as Figure 2 As shown, the flexible air guide shroud 42 can be a flexible corrugated structure and can be extended and contracted, thereby ensuring that the upper end of the first rigid air guide shroud 41 can move up and down with the upper end of the first vertical plate of the H-shaped baffle 31.

[0093] In other words, the middle part of the air guide shroud assembly 4 (i.e., the flexible air guide shroud 42) can be extended and retracted, thereby ensuring that the upper end of the air guide shroud assembly 4 can move up and down following the upper end of the first vertical plate of the H-shaped baffle 31.

[0094] Furthermore, the materials of the first rigid air guide shroud 41 and / or the second rigid air guide shroud 43 include: stainless steel sheet or plexiglass sheet;

[0095] The flexible air guide shroud 42 is made of nylon or fiber cloth. Both nylon and fiber cloth are high-temperature resistant and flexible materials. In other words, this material selection for the air guide shroud is advantageous due to the availability of materials and ease of molding.

[0096] In this plan, such as Figure 1 As shown, there are multiple inverter cabinets 7, and these multiple inverter cabinets 7 are arranged side by side;

[0097] The electrical room 6 has multiple exhaust vents 61, which correspond one-to-one with multiple frequency converter cabinets 7;

[0098] There are multiple ventilation and heat dissipation devices, and these devices are installed one by one between multiple frequency converter cabinets 7 and multiple exhaust vents 61 of electrical room 6.

[0099] It should be noted that, as Figure 1As shown, multiple inverter cabinets 7 are arranged side-by-side adjacent to the first wall 62 of the electrical room 6. Multiple exhaust vents 61 are provided on the first wall 62 of the electrical room 6, located above the exhaust vents on the top of each inverter cabinet 7. The aforementioned ventilation and heat dissipation device is then configured between the exhaust vent and the corresponding exhaust vent 61 on the top of each inverter cabinet 7. This facilitates the exhaust of hot air generated by the multiple inverter cabinets 7 outside the electrical room, significantly reducing the number and power of air conditioners in the electrical room, further reducing energy consumption, costs, and environmental friendliness. In addition, other cabinets or equipment are also arranged in this electrical room; for details, please refer to [link to relevant documentation]. Figure 1 As shown.
