Description

Technical Field

[0001] This utility model relates to the field of generator excitation control technology, specifically to a heat dissipation cabinet for a generator excitation control device. Background Technology

[0002] As a key component of excitation system electronic equipment, the optimized design of heat dissipation devices is of great value in improving the operating environment of the equipment. By properly controlling the operating temperature of power devices, not only can the heat resistance stability of insulation materials be significantly improved, but the aging rate of semiconductor components can also be effectively slowed down.

[0003] In the heat dissipation design of generator excitation control devices, forced air cooling is typically used to cool the electronic components inside the cabinet. For example, patent CN205070462U discloses a diesel generator set control cabinet for a generator grid-connected control system, which includes a first cabinet, a second cabinet, a third cabinet, and a fourth cabinet. Each unit control cabinet and the integrated control cabinet has running indicator lights, online indicator lights, fault indicator lights, and emergency stop indicator lights on their doors, providing rich indication functions. On-site operators can confirm whether the emergency stop button is active through the emergency stop indicator lights, making it more convenient and safer to use. The location of the heat dissipation windows is coordinated with the location of the transformer and battery, allowing for concentrated and rapid heat dissipation for the transformer and battery, which generate a lot of heat.

[0004] However, in existing control devices, the heat dissipation ducts are mostly straight structures with short airflow paths and limited heat dissipation efficiency. This makes it difficult to achieve uniform heat dissipation in a limited space, resulting in uneven temperature distribution inside the cabinet. This can easily lead to localized heat accumulation, affecting the stability and service life of the equipment. Utility Model Content

[0005] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose a heat dissipation cabinet for a generator excitation control device, which solves the technical problems of short airflow path in the heat dissipation duct, limited heat dissipation efficiency, uneven temperature distribution inside the cabinet, and local heat accumulation in the prior art.

[0006] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

[0007] This utility model provides a heat dissipation cabinet, including: a cabinet body, several partition components, and a heat dissipation component. The cabinet body is provided with an air inlet and an air outlet communicating with the interior. The several partition components are arranged sequentially and at intervals inside the cabinet body along the ventilation direction from the air inlet to the air outlet, dividing the internal cavity of the cabinet body into multiple sequentially arranged heat dissipation air ducts. The first heat dissipation air duct is connected to the air inlet, and the last heat dissipation air duct is connected to the air outlet. Each partition component forms an air guide between itself and the inner wall of the cabinet body. The air guide is used to connect adjacent heat dissipation air ducts. Each air guide is alternately arranged on different sides of the cabinet body along the ventilation direction. The heat dissipation component is installed inside the cabinet body and corresponds to the heat dissipation air ducts, and is used to drive the airflow to flow directionally from the air inlet to the air outlet.

[0008] In some embodiments, the partition component includes a fixed partition and a movable partition. The fixed partition is horizontally disposed inside the cabinet near the cabinet door, and its two sides are connected to the cabinet. A sliding groove is provided between the two sides. The movable partition is installed in the sliding groove and can slide relative to the cabinet door. Corresponding air vents are provided on one side of the fixed partition and the movable partition.

[0009] In some embodiments, the partition assembly further includes a drive member connecting the fixed partition and the movable partition, for driving the movable partition to slide relative to the cabinet door along a slide groove.

[0010] In some embodiments, the drive member includes a screw and a handle, one end of the screw being threadedly connected to the movable spacer, and the other end passing through the fixed spacer and having a handle thereon, the screw being rotatably connected to the fixed spacer.

[0011] In some embodiments, a mounting groove is provided on one side of the fixing spacer at a position corresponding to the handle, and the handle is located in the mounting groove.

[0012] In some embodiments, slide rails are provided on both sides of the inner wall of the cabinet and at corresponding positions on both sides of the partition component, and the partition component is slidably installed in the cabinet via the slide rails.

[0013] In some embodiments, an air outlet cover is provided at one end of the air outlet of the cabinet, and heat dissipation holes are provided on all sides of the air outlet cover.

[0014] In some embodiments, the heat dissipation assembly includes a mounting bracket, a cooling fan, and a heat sink assembly. The cooling fan is mounted inside the cabinet via the mounting bracket, and the heat sink assembly is disposed on one side of the cooling fan.

[0015] In some embodiments, the heat dissipation component is disposed at the air inlet of the cabinet.

[0016] Compared with existing technologies, the generator excitation control device heat dissipation cabinet provided by this utility model, through its cabinet body, several partition components, and heat dissipation components, divides the internal cavity of the cabinet into multiple sequentially arranged heat dissipation air ducts. The staggered distribution of air vents creates a serpentine flow of air, effectively extending the airflow path and enhancing heat exchange. This ensures uniform airflow distribution within the cabinet, avoiding localized overheating and significantly improving heat dissipation efficiency. This enhances the operational stability and reliability of power electronic equipment such as generator excitation control devices. Furthermore, the multiple partition components enable a compact air duct layout, achieving efficient heat dissipation within a limited space. This makes it suitable for high power density applications and allows for flexible adaptation to different heat dissipation requirements by adjusting the partition components.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0028] To address the technical problems of short airflow paths, limited heat dissipation efficiency, uneven temperature distribution within the cabinet, and localized heat accumulation in the cooling duct, this utility model provides a heat dissipation cabinet for a generator excitation control device. This cabinet ensures uniform airflow distribution within the cabinet, avoids localized overheating, significantly improves heat dissipation efficiency, and enhances the operational stability and reliability of power electronic equipment such as generator excitation control devices.

[0029] Please see Figure 1 and Figure 2 This application provides a heat dissipation cabinet for a generator excitation control device, including: a cabinet body 1, several partition components 2, and a heat dissipation component 3. The cabinet body 1 is provided with an air inlet 11 and an air outlet 12 communicating with the interior. Several partition components 2 are arranged sequentially and at intervals inside the cabinet body 1 along the ventilation direction from the air inlet 11 to the air outlet 12, dividing the inner cavity of the cabinet body 1 into multiple sequentially arranged heat dissipation air ducts. The first heat dissipation air duct is connected to the air inlet 11, and the last heat dissipation air duct is connected to the air outlet 12. An air guide 201 is formed between each partition component 2 and the inner wall of the cabinet body 1. The air guide 201 is used to connect adjacent heat dissipation air ducts. Each air guide 201 is alternately arranged on different sides of the cabinet body 1 along the ventilation direction, so that the airflow enters the cabinet body 1 through the air inlet 11 and flows in a tortuous manner along the heat dissipation air duct. The heat dissipation component 3 is installed inside the cabinet body 1 and corresponds to the heat dissipation air duct, and is used to drive the airflow to flow directionally from the air inlet 11 to the air outlet 12.

[0030] In this device, the cabinet 1 is equipped with an air inlet 11 and an air outlet 12 that communicate with the interior. With the help of the heat dissipation component 3, outside air can enter the cabinet 1 through the air inlet 11 and then exit through the air outlet 12, allowing for directional airflow and further improving heat dissipation. Because the partition component 2 divides the interior of the cabinet 1 into multiple sequentially arranged heat dissipation channels, and the air guide vents 201 formed between each partition component 2 and the inner wall of the cabinet 1 are alternately arranged on different sides of the cabinet 1 along the ventilation direction, the airflow enters the cabinet 1 through the air inlet 11 and then flows in a tortuous manner along the heat dissipation channels, effectively extending the airflow path and improving heat dissipation efficiency. This device has a simple structure and is easy to maintain, meeting the high-efficiency heat dissipation requirements of the generator excitation control device.

[0031] It should be noted that this solution does not limit the number of partition components 2, and can be reasonably set according to actual heat dissipation requirements and the internal space size of cabinet 1. The heat dissipation cabinet can be composed of multiple or a single cabinet 1, with electrical components installed inside to form the entire generator excitation control device. Cabinet 1 operates in a closed manner, with a door frame on its front and a cabinet door 13 that can be opened or closed. The door 13 frame is equipped with a sealing strip to ensure the airtightness of the cabinet 1 and prevent dust from entering. Cabinet 1 can exchange heat with the outside air through the internal heat dissipation ducts. Both the air inlet 11 and the air outlet 12 are equipped with dust filters to prevent dust and other impurities from entering the cabinet 1 and affecting the normal operation of the electrical components.

[0032] Furthermore, in some possible embodiments, an air hood 14 is fixedly provided at the top of the cabinet 1, and heat dissipation holes are provided on all sides of the air hood 14. The heat dissipation holes form air outlets 12, which can guide the airflow inside the cabinet 1 to be discharged evenly from all directions.

[0033] Preferably, in this embodiment, the air inlet 11 and air outlet 12 of the cabinet 1 are respectively located at its bottom and top. The partition component 2 is horizontally installed inside the cabinet 1, and three sets of partition components 2 are provided to divide the inner cavity of the cabinet 1 into four heat dissipation ducts. Air can enter from the air inlet 11 at the bottom of the cabinet 1, exchange heat with the electrical components inside the cabinet 1 as it passes through each heat dissipation duct, and then be discharged from the air outlet 12 at the top of the cabinet 1 after absorbing heat.

[0034] Please see Figures 2 to 5In the generator excitation control device, electrical components are generally installed on the back of the inner wall of the cabinet 1. Due to the differences in the size of the electrical components, the space inside the cabinet 1 for installing the partition assembly 2 becomes uneven. Therefore, in this embodiment, the partition assembly 2 includes a fixed partition 21, a movable partition 22, and a driving component 23. The fixed partition 21 is horizontally arranged inside the cabinet 1 near the cabinet door 13, with its two sides connected to the cabinet 1, and a sliding groove 212 is provided between the two sides. When the cabinet door 13 is closed, the inner wall of the cabinet door 13 can be in close contact with the front of the fixed partition 21. The movable partition 22 is installed in the sliding groove 212 and can slide relative to the cabinet door 13, thereby adjusting the position of the movable partition 22 inside the cabinet 1 to accommodate electrical components of different sizes and ensure effective separation of the heat dissipation air duct. The driving component 23 connects the fixed partition 21 and the movable partition 22 and is used to drive the movable partition 22 to slide relative to the cabinet door 13 along the sliding groove 212. Specifically, when the electrical components installed inside cabinet 1 are large, the movable partition 22 can be driven by the drive component 23 to slide along the slide groove 212 to a position close to the fixed partition 21, thereby reducing the distance between the movable partition 22 and the inner wall of cabinet 1. Conversely, when the electrical components installed inside cabinet 1 are small, the movable partition 22 can be driven by the drive component 23 to slide along the slide groove 212 to a position away from the fixed partition 21, thereby increasing the distance between the movable partition 22 and the inner wall of cabinet 1. This design not only improves the flexibility and adaptability of the heat dissipation cabinet but also ensures optimal heat dissipation.

[0035] Preferably, in this embodiment, both the fixed partition 21 and the movable partition 22 are partitions, namely a fixed partition 211 and a movable partition 221, and the driving component 23 includes a screw 231 and a handle 232. Specifically, slide rails 15 are provided on both sides of the inner wall of the cabinet 1 and on the corresponding positions of the two sides of the partition component 2. The two ends of the fixed partition 211 can extend into the groove of the slide rail 15 and slide in slidably connected with the slide rail 15. The interior of the fixed partition 211 is provided with a slide groove 212, and the two ends of the slide groove 212 penetrate through the two ends of the fixed partition 211. The movable partition 221 is slidably disposed in the slide groove 212 on the inner side of the fixed partition 211, and the bottom two sides of the movable partition 221 are provided with sliders 222 that cooperate with the slide rail 15. The sliders 222 can slide relative to the groove of the fixed partition 211 and the slide rail 15. A threaded hole 223 is opened on the side of the movable partition 221 near the cabinet door 13. The screw 231 is arranged horizontally. One end of the screw 231 is threadedly connected to the threaded hole 223 of the movable partition 221, and the other end passes through the fixed partition 211 and is provided with a handle 232. The screw 231 is rotatably connected to the through position of the fixed partition 211. The handle 232 is located on the front of the fixed partition 211, which makes it convenient to use the handle 232 to adjust the position of the movable partition 221 at the cabinet door 13.

[0036] In use, the operator can manually hold and rotate the handle 232. Since the screw 231 is threadedly connected to the threaded hole 223 of the movable partition 221, when the handle 232 is rotated, the screw 231 will drive the movable partition 221 to slide along the slide groove 212, thereby adjusting the position of the movable partition 221. The operator can easily adjust the position of the movable partition 221 through the cabinet door 13, improving the convenience and safety of operation.

[0037] Furthermore, in some embodiments, a mounting groove 213 is provided on one side of the fixing partition 21 at the position corresponding to the handle 232, and the handle 232 is located in the mounting groove 213 to prevent the handle 232 from protruding and affecting the tightness of the cabinet door 13 when closing.

[0038] It should be noted that the size and shape of the movable partition 221 can be adjusted according to the internal space of the cabinet 1 and the structure and installation position of the electrical components, ensuring that the movable partition 221 can fit tightly against the inner wall of the cabinet 1 or against other electrical components inside the cabinet 1, thereby achieving effective separation of the heat dissipation airflow. The design of this device allows the corresponding partition components 2 to be installed after the internal electrical components are installed, thus enabling flexible adjustment of the partition configuration according to the actual layout and size of the electrical components. This installation method not only simplifies the assembly process of the heat dissipation cabinet but also improves its adaptability to the heat dissipation requirements of different generator excitation control devices.

[0039] Please see Figure 2 and Figure 6 Preferably, in this embodiment, the heat dissipation component 3 is disposed at the air inlet 11 of the cabinet 1, and includes a mounting bracket 31, a cooling fan 32, and a heat sink assembly 33. The mounting bracket 31 is fixed to the bottom of the cabinet 1 by bolts. The air inlet 11 is provided on the bottom side of the cabinet 1. Multiple cooling fans 32 are provided and are horizontally arrayed on the mounting bracket 31. The heat sink assembly 33 is mounted on the mounting bracket 31 and located at the bottom of the cooling fan 32. When the cooling fan 32 is running, it can drive air from the air inlet 11 into the cabinet 1. The cooling end of the heat sink can cool the incoming air inside the cabinet 1. The cooled air flows in a tortuous manner along the heat dissipation duct under the action of the cooling fan 32, and fully exchanges heat with the electrical components inside the cabinet 1, absorbing the heat generated by the electrical components, and finally is discharged from the air outlet 12 at the top of the cabinet 1.

[0040] Of course, in other embodiments, the specific forms of the partition component 2 and the heat dissipation component 3 are not limited to this. The partition component 2 can divide the inner cavity of the cabinet 1 into multiple heat dissipation channels arranged in sequence, and the heat dissipation component 3 can make the airflow flow in a tortuous manner along the heat dissipation channels.

[0041] To better understand this utility model, the following is combined with... Figures 1 to 6The technical solution of this utility model is described in detail as follows: When installing the partition component 2, the operator first needs to determine the layout and size of the electrical components inside the cabinet 1. Then, a suitable movable partition 221 is selected. After installing the fixed partition 211 on the slide rail 15 on the inner wall of the cabinet 1, the handle 232 is rotated to adjust the position of the movable partition 221 in the slide groove 212, ensuring that the movable partition 221 can fit tightly against the inner wall of the cabinet 1 or against other electrical components inside the cabinet 1. During the heat dissipation process, the cooling fan 32 is started, driving outside cold air into the cabinet 1 through the air inlet 11 at the bottom, and undergoing initial cooling through the cooling end of the heat sink assembly 33. Subsequently, under the action of the cooling fan 32, the cold air flows along the tortuous heat dissipation channel formed by the partition component 2. During the flow, the cold air undergoes sufficient heat exchange with the electrical components inside the cabinet 1, absorbing the heat generated by the electrical components. Finally, the heated hot air is discharged from the air outlet 12 at the top of the cabinet 1, achieving heat dissipation.

[0042] This invention utilizes a cabinet 1, several partition components 2, and a heat dissipation component 3. The partition components 2 divide the interior of the cabinet 1 into multiple sequentially arranged heat dissipation air ducts, and the staggered air guides 201 create a serpentine airflow pattern, effectively extending the airflow path and enhancing heat exchange. This ensures uniform airflow distribution within the cabinet 1, preventing localized overheating and significantly improving heat dissipation efficiency. This enhances the operational stability and reliability of power electronic equipment such as generator excitation control devices. Furthermore, the multiple partition components 2 enable a compact air duct layout, achieving efficient heat dissipation within a limited space. This design is suitable for high-power-density applications and can be flexibly adapted to different heat dissipation requirements by adjusting the partition components 2.
