Description

Technical Field

[0001] This application relates to the field of wind power generation equipment technology, specifically to a torsion-resistant heat dissipation bracket for a wind turbine tower electrical cabinet. Background Technology

[0002] In harsh outdoor environments such as wind turbine towers, electrical control cabinets typically require brackets for stable support, and the issues of heat dissipation and dust prevention must be addressed. In existing technologies, the support structure and cooling ducts of electrical control cabinets are often designed independently. The support components only bear mechanical loads, while heat dissipation relies on external fans or independent ducts. This separate design not only results in a large overall size and low space utilization, but also makes it difficult to achieve efficient heat dissipation while maintaining a high level of protection. Furthermore, traditional brackets lack optimized design for airflow organization; external cold air entering the cabinet is not effectively pre-filtered and guided, easily causing dust accumulation that affects the lifespan of electrical components. Additionally, the support structure lacks stability under torsional loads, failing to meet the long-term reliable operation requirements under harsh conditions. Summary of the Invention

[0003] To address the problems of low space utilization and poor dustproof and heat dissipation effects caused by the independent support structure and heat dissipation duct in existing technologies, this application achieves integrated and coordinated support and torsion resistance and multi-level dustproof and heat dissipation through a torsion-resistant heat dissipation bracket for the electrical cabinet of the wind turbine tower.

[0004] To achieve the above objectives, this application adopts the following technical solution: A torsion-resistant heat dissipation support for a wind turbine tower electrical cabinet includes a support platform with a ventilation channel inside; a filter cylinder with an air inlet pipe installed below it and the upper part of the filter cylinder connected to the ventilation channel; heat dissipation pipes; and a first heat dissipation plate and a second heat dissipation plate connected between the heat dissipation pipes; wherein the bottom end of the first heat dissipation plate is connected to the ventilation channel, and the second heat dissipation plate is connected to the heat dissipation pipes; the airflow is configured such that after entering the filter cylinder from the air inlet pipe for filtration, it is distributed to the first heat dissipation plate and the heat dissipation pipes through the ventilation channel.

[0005] The above solution forms a primary air duct by connecting the bottom air intake filter assembly with the built-in air duct of the support platform, and forms a secondary air duct by combining it with a frame-type heat dissipation support assembly composed of heat dissipation pipes and heat dissipation plates. This allows the airflow to enter from the air intake pipe, pass through primary filtration and distribution, and then be guided to the heat dissipation assembly, thus realizing the functional integration of the support structure and the heat dissipation air duct, and improving the space utilization and airflow organization efficiency.

[0006] In one implementation, the filter cartridge is vertically arranged, with its upper end passing through the support platform and communicating with the air passage, and its lower end connected to the air intake pipe; the surface of the air passage is covered with a filter screen.

[0007] This implementation method uses vertically arranged filter cartridges and a support platform as an airflow distribution cavity, combined with a filter screen on the surface of the air passage for secondary interception, which further enhances the dust prevention capability of the air intake end, while ensuring the uniformity of airflow before entering the heat dissipation components.

[0008] In one implementation, support legs are installed below the support platform, and reinforcing ribs are installed between adjacent support legs and the support platform. The two opposite support legs are connected by fixed rods, and the filter cylinder is installed on the fixed rods.

[0009] This embodiment utilizes support legs, reinforcing ribs, and fixing rods to form a stable bottom support frame, and integrates the filter cartridge inside the frame. This not only improves the overall torsional rigidity of the support frame, but also avoids the filter assembly occupying additional external space, thus enhancing the compactness and mechanical reliability of the structure.

[0010] In one implementation, the heat pipes are arranged in a vertical cross shape, and the first heat sink and the second heat sink are installed between the heat pipes and the mounting bracket, with the first heat sink and the second heat sink distributed vertically.

[0011] This implementation method constructs a three-dimensional frame that combines load-bearing and air-guiding functions by orthogonally connecting vertical heat pipes and horizontal multi-layer heat dissipation plates. The heat dissipation plates distributed vertically can guide airflow in layers, increasing the heat exchange area and enhancing the lateral support and anti-torsional performance of the bracket for the electrical cabinet.

[0012] In one implementation, the bends in the heat pipes are arc-shaped; both the first and second heat sinks have several openings, and filter blocks are installed at each opening.

[0013] In this embodiment, the arc-shaped bend reduces turbulence and pressure loss when the airflow changes direction, ensuring smooth airflow. The openings and filter blocks on the heat sink implement three-stage filtration when the airflow passes through the heat sink components, preventing fine particles from entering the outer wall area of ​​the electrical cabinet, thus achieving both low wind resistance heat dissipation and deep dust protection.

[0014] In one implementation, the support platform is provided with insertion holes, and a mounting bracket is installed in the insertion holes. A fixing bracket is installed on the top of the mounting bracket. An inspection door is also installed on the support platform.

[0015] This implementation method enables rapid positioning and assembly of the heat dissipation support components through the cooperation of the insertion hole and the mounting bracket. The fixing bracket is used to lock the electrical cabinet body, and the inspection door facilitates the maintenance and cleaning of the internal filter and air duct, thereby improving the maintainability and assembly efficiency of the equipment. Beneficial effects

[0016] This application changes the traditional design paradigm of separating support and heat dissipation by integrating the ventilation duct within the support platform as both a structural reinforcement and an airflow distribution channel, and by integrating the filter cartridge, heat dissipation pipes, and heat dissipation plates into a single torsional heat dissipation frame. Airflow enters the filter cartridge through the bottom air intake pipe for initial filtration, and is then evenly distributed to the first heat dissipation plate and heat dissipation pipes by the ventilation ducts on the support platform. After further filtration by the filter blocks on the heat dissipation plate, the air cools the outer wall of the electrical cabinet. Simultaneously, the cabinet's built-in fan can directly draw in pre-treated air from the support platform area to dissipate heat from the internal components. This structure, on the one hand, utilizes frame-type heat dissipation components to bear mechanical loads, improving the torsional stiffness and space utilization of the support; on the other hand, it constructs a multi-stage dustproof and heat dissipation path of "bottom initial filtration - platform distribution - component fine filtration - internal and external coordination," reducing wind resistance while ensuring a high level of protection, and achieving a synergistic improvement in structural strength, heat dissipation efficiency, and dustproof performance.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains. Example

[0021] like Figure 1 and Figure 3As shown, this embodiment provides a torsional cooling support for a wind turbine tower electrical cabinet, which integrates a mechanical support structure with a cooling duct. Specifically, the torsional cooling support includes a support platform 1, within which a ventilation duct 3 is formed. In this embodiment, the ventilation duct 3 serves not only as a channel for delivering cooling airflow but also as a structural reinforcing rib within the support platform 1. This dual-function design allows the support platform 1 to maintain a lightweight and compact size while significantly improving its overall torsional stiffness, effectively resisting deformation caused by external loads. It should be understood that the specific cross-sectional shape, number, and extension path of the ventilation duct 3 within the support platform 1 can be adjusted according to actual load-bearing and airflow requirements. For example, it can be configured as a horizontally continuous, vertically continuous, or grid-like intersecting distribution, as long as it achieves the synergistic effect of airflow distribution and structural reinforcement.

[0022] The anti-torsion heat dissipation bracket of the electrical cabinet also includes a filter cartridge 9. An air inlet pipe 10 is installed below the filter cartridge 9, and the top of the filter cartridge 9 is connected to the ventilation duct 3. Specifically, the air inlet pipe 10 serves as an inlet for external cold air, introducing ambient air into the filter cartridge 9 for preliminary purification. The filter cartridge 9 acts as a primary filtration unit and an airflow buffer chamber, with its top directly connected to the ventilation duct 3 inside the support platform 1, allowing the pre-filtered airflow to enter the ventilation duct 3 unimpeded for subsequent distribution. This vertically connected layout with bottom air intake and top airflow guidance is beneficial for utilizing the principle of gravity settling to assist in the separation of large dust particles, while shortening the air intake path and reducing unnecessary pressure loss. In other embodiments, the filter cartridge 9 and the ventilation duct 3 can also be indirectly connected via a transition flange or sealing gasket, as long as the airtightness and flow area meet the heat dissipation requirements.

[0023] The anti-torsion heat dissipation bracket for the electrical cabinet also includes heat dissipation pipes 13, and a first heat dissipation plate 14 and a second heat dissipation plate 15 connected between the heat dissipation pipes 13. Figure 3As shown, the heat pipe 13, the first heat sink 14, and the second heat sink 15 together constitute a three-dimensional frame-type heat dissipation support assembly. The bottom end of the first heat sink 14 is connected to the ventilation duct 3, and the second heat sink 15 is connected to the heat pipe 13. This specific positional connection is the key structural basis for achieving precise airflow distribution in this embodiment. Specifically, the first heat sink 14 is located at the downstream starting end of the airflow distribution, and its bottom end directly receives the airflow from the ventilation duct 3, making the first heat sink 14 part of the main air intake channel; while the second heat sink 15 obtains airflow through its connection with the heat sink 13, forming a secondary or parallel heat dissipation path. This differentiated connection method avoids the problems of airflow short-circuiting or uneven distribution, ensuring that heat dissipation surfaces at different heights can obtain effective cooling medium. It should be noted that although the figure shows the layout with the first heat sink 14 below and the second heat sink 15 above, in other embodiments, the relative positions of the two can be interchanged or adjusted according to the distribution of heat-generating components inside the electrical cabinet, as long as the established connection logic between each and the ventilation duct 3 or heat sink 13 remains unchanged.

[0024] In this embodiment, the airflow is configured to enter the filter cartridge 9 from the intake pipe 10 for filtration, and then be distributed to the first heat sink 14 and the heat dissipation pipe 13 via the ventilation duct 3. This functional limitation clearly defines the complete airflow organization path inside the support. During operation, external cold air is drawn in through the intake pipe 10 under negative or positive pressure, and first, large particulate impurities are intercepted in the filter cartridge 9. Subsequently, the clean airflow rises and enters the ventilation duct 3 of the support platform 1. The ventilation duct 3 acts as a pressure-stabilizing and distribution chamber, evenly guiding the airflow to the bottom opening of the first heat sink 14 and the inlet of the heat dissipation pipe 13. As the airflow flows through the first heat sink 14 and the heat dissipation pipe 13, it carries away heat and ultimately acts on the outer wall of the electrical cabinet or is discharged. Through the above structure, this embodiment transforms the originally independent support component into an organic component of the heat dissipation duct, which not only solves the problem of low space utilization in traditional supports, but also ensures a balance between heat dissipation efficiency and protection level through the integrated airflow path design, providing a reliable guarantee for the stable operation of the electrical cabinet in harsh environments. Example

[0025] Based on Example 1, this example further describes the integrated structure and support system of the bottom air intake filter assembly and the supporting platform. For example... Figure 1 and Figure 2As shown, the filter cartridge 9 is vertically arranged, with its upper end passing through the support platform 1 and connecting to the ventilation duct 3, and its lower end connecting to the air intake pipe 10. Specifically, this vertical through-type layout design makes the filter cartridge 9 not only an airflow purification unit, but also a structural link connecting the bottom air intake and the top support platform 1. The vertical orientation is beneficial for utilizing the principle of gravity settling, allowing large dust particles entering the filter cartridge 9 to naturally settle to the bottom dust collection area or the lowest point of the air intake pipe 10 under the action of gravity, reducing the direct impact on the filter element surface and the risk of clogging, thereby extending the maintenance cycle. At the same time, the vertical flow channel can significantly reduce local pressure loss compared to the horizontal bending flow channel, ensuring that the airflow enters the ventilation duct 3 inside the support platform 1 with higher kinetic energy, providing a sufficient static pressure foundation for subsequent multi-path distribution. It should be understood that although the filter cartridge 9 is arranged vertically in a cylindrical shape in this embodiment, in other embodiments, it can also be adjusted to an elliptical cylinder or a polygonal prism shape according to the internal space constraints of the cabinet, as long as the axis is kept approximately perpendicular to the plane of the support platform 1 to achieve the gravity-assisted separation function.

[0026] The surface of the ventilation duct 3 is covered with a filter screen 5. In this embodiment, the filter screen 5 serves as a secondary protective barrier, directly attached to or embedded in the opening surface of the ventilation duct 3 facing the interior of the electrical cabinet. When airflow enters the ventilation duct 3 from the filter cartridge 9 and attempts to overflow, it must pass through the filter screen 5. This effectively intercepts fine particles that may escape due to the failure of the filter cartridge 9's seal or fluctuations in the initial filtration efficiency, ensuring the cleanliness of the airflow that ultimately enters the heat dissipation components. More importantly, the filter screen 5 is not merely a consumable material; it forms a composite reinforcement structure with the surface of the ventilation duct 3. For example, when the filter screen 5 is made of metal wire mesh and fixed to the edge of the ventilation duct 3 by spot welding or riveting, it can act as a tension support similar to a skin, suppressing the deformation tendency of the ventilation duct 3 opening when the bearing platform 1 is subjected to eccentric loads. Of course, the specific form of the filter screen 5 is not limited to metal mesh; it can also be a high-strength nylon mesh or a sintered porous plate, as long as it has air permeability and a certain structural rigidity.

[0027] To further enhance the overall structural mechanical performance, support legs 6 are installed below the load-bearing platform 1. Reinforcing ribs 7 are installed between adjacent support legs 6 and the load-bearing platform 1. Opposite support legs 6 are connected by fixing rods 8, and the filter cartridge 9 is mounted on the fixing rods 8. Specifically, the support legs 6, reinforcing ribs 7, and fixing rods 8 together form a high-rigidity bottom torsional frame. The support legs 6, as the main vertical load-bearing components, transfer the weight of the electrical cabinet to the ground or mounting base. The reinforcing ribs 7 fill the corner area formed by the support legs 6 and the load-bearing platform 1, effectively dispersing stress concentration at the connection point and preventing fatigue cracking under wind loads or vibration conditions. In particular, the fixing rods 8 connect the opposite support legs 6 laterally, not only eliminating the horizontal freedom of the support legs 6 and significantly improving the support's ability to resist lateral torsional moments, but also providing a stable mounting reference for the filter cartridge 9. Suspending or supporting the filter cartridge 9 on the fixing rods 8 achieves deep integration of functional components and the load-bearing frame, avoiding the space waste and center of gravity shift caused by setting up separate external supports for the filter assembly. This integrated design allows the support to maintain excellent dynamic stability despite its compact size. It should be noted that although the figure shows four support legs 6 and triangular reinforcing ribs 7, this is only a preferred example. In practical applications, the number of support legs 6 can be adjusted to three, six, or more depending on the load-bearing capacity; the shape of the reinforcing ribs 7 can also be trapezoidal, arc-shaped, or a plate structure with weight-reducing holes; the connection between the fixing rod 8 and the support legs 6 can be welding, bolting, or mortise and tenon joints, as long as it forms a closed load-bearing frame and provides reliable support for the filter cartridge 9, it should be covered within the scope of this application. Example

[0028] Based on Example 1, this example further describes in detail the three-dimensional structure and airflow filtration details of the frame-type heat dissipation support assembly. For example... Figure 3As shown, the heat dissipation pipes 13 are arranged in a vertical cross shape, and the first heat dissipation plate 14 and the second heat dissipation plate 15 are installed between the heat dissipation pipes 13 and the mounting bracket 11, with the first heat dissipation plate 14 and the second heat dissipation plate 15 distributed vertically. Specifically, this vertically cross-shaped arrangement of the heat dissipation pipes 13 constitutes the main load-bearing skeleton of the bracket, which can efficiently transfer loads and resist lateral overturning moments. The first heat dissipation plate 14 and the second heat dissipation plate 15 are not merely functional accessories; they are securely assembled as horizontal connecting parts within the space enclosed by the heat dissipation pipes 13 and the mounting bracket 11, forming a high-rigidity frame structure together with the vertical components. This orthogonal frame design enables the heat dissipation components themselves to possess the mechanical properties to replace traditional independent support beams, achieving a deep integration of structural and functional components. At the same time, the vertically spaced distribution of the first heat dissipation plate 14 and the second heat dissipation plate 15 in the height direction divides the originally single air intake channel into multi-level airflow channels. When airflow enters through the bottom vent 3, it is orderly diverted and guided by the two heat dissipation plates, preventing disordered vortices or local short circuits within the frame and ensuring uniform cooling coverage across different height areas of the electrical cabinet's outer wall. It should be understood that although a cross-shaped layout is used in this embodiment, in other embodiments, the heat dissipation pipe 13 can be adjusted to a rectangular frame, hexagonal honeycomb, or other polygonal frame structure depending on the cabinet's cross-sectional shape, as long as it maintains the synergistic effect of vertical load-bearing and horizontal connection.

[0029] To further optimize airflow quality and efficiency, the bends in the heat dissipation pipe 13 are curved; both the first heat dissipation plate 14 and the second heat dissipation plate 15 have several openings, and filter blocks 16 are installed at each opening. Specifically, the heat dissipation pipe 13 uses curved transitions at corners or connections instead of right-angle splicing. This design, based on fluid mechanics principles, can effectively guide the airflow to smoothly change direction, significantly reducing turbulence and pressure loss caused by sudden changes in flow direction. Under the premise of constant fan power, reducing wind resistance means obtaining a larger effective air volume, thereby improving the overall heat dissipation efficiency; at the same time, smooth airflow also helps to reduce aerodynamic noise and improve the equipment operating environment. On the other hand, the filter blocks 16 located at the openings of the first heat dissipation plate 14 and the second heat dissipation plate 15 constitute the last line of defense in the multi-stage dustproof system of this application. After the airflow has passed through the initial filtration of the bottom filter cylinder 9 and the secondary interception of the surface filter screen 5 of the air passage 3, it will be finely filtered again by the filter blocks 16 when flowing through the openings of the heat dissipation plate, thoroughly removing fine dust particles. This design, which integrates the fine filtration unit directly into the heat dissipation channel, not only saves additional filter installation space but, more importantly, ensures that the airflow that ultimately contacts the outer wall of the electrical cabinet achieves extremely high cleanliness, fundamentally eliminating the problem of increased thermal resistance caused by dust accumulation. In practical applications, the filter block 16 can be fixed by a detachable snap-fit ​​or magnetic method, facilitating regular cleaning or replacement; its filter material can also be selected from high-density sponge, non-woven fabric, or activated carbon composite materials depending on the dust content of the environment. Through the combination of the aforementioned arc-shaped airflow and embedded fine filtration, this embodiment successfully constructs a three-in-one synergistic mechanism of "support-heat dissipation-dust prevention," enabling the support to maintain excellent overall performance even under harsh operating conditions. Example

[0030] Based on Example 1, this example further details the installation positioning and maintenance structure on the support platform. For example... Figure 1 and Figure 2As shown, the support platform 1 has an insertion hole 4, in which a mounting bracket 11 is installed. A fixing bracket 12 is installed on the top of the mounting bracket 11. An inspection door 2 is also installed on the support platform 1. Specifically, the insertion hole 4 serves as a precision interface between the mounting bracket 11 and the support platform 1, and its positional accuracy directly determines the alignment between the upper heat dissipation support assembly and the lower ventilation duct 3. Through the guiding and limiting function of the insertion hole 4, the mounting bracket 11 can achieve rapid self-positioning during assembly without relying on complex external tooling or repeated measurement and calibration. This not only significantly improves on-site assembly efficiency but also ensures the sealing and accuracy of the airflow connection between the heat pipe 13 and the heat sink plate and the ventilation duct 3. It should be understood that although the insertion hole 4 shown in the figure is a rectangular through hole, in other embodiments, it can also be designed as a circle, ellipse, or polygon, or even an irregularly shaped hole with a foolproof notch, as long as it can achieve the axial limiting and circumferential orientation functions of the mounting bracket 11.

[0031] The fixing bracket 12 installed at the top of the mounting frame 11 plays a crucial role in securely locking the electrical cabinet body onto the support. In this embodiment, the fixing bracket 12 is located at the highest point of the mounting frame 11, in a mechanical position most favorable for resisting overturning moments. After the electrical cabinet body is placed on the support platform 1, the fixing bracket 12 applies restraint to the cabinet from the side or top, connecting it to the anti-torsion heat dissipation support below, effectively preventing relative displacement or swaying of the equipment under transportation vibration or external wind load. This design, which integrates the locking point at the top of the heat dissipation support frame, avoids the waste of space and redundancy of parts caused by adding additional independent clamps or pressure plates. In practical applications, the fixing bracket 12 can be in the form of an L-shaped bent plate, a U-shaped slot, or an adjustable screw assembly, and its connection method can be bolt fastening, quick snap fastening, or welding fixation. As long as it can provide sufficient clamping force and maintain structural continuity with the mounting frame 11, it should be covered within the scope of protection of this application.

[0032] The maintenance door 2 installed on the support platform 1 provides a convenient passage for the later operation and maintenance of the equipment. Since the filter cartridge 9 is a consumable that requires regular cleaning or replacement, the maintenance door 2 allows maintenance personnel to directly access the internal filter components for maintenance without disassembling the entire support frame or removing the electrical cabinet. This not only significantly reduces the labor intensity and downtime of maintenance work, but more importantly, it avoids the risk of loose connections or seal failure caused by frequent disassembly and reassembly of the main structure. When closed, the maintenance door 2 should be flush with or tightly fitted to the surface of the support platform 1 to maintain the overall protection level and appearance integrity; when open, it should provide sufficient operating space. It should be noted that the opening and closing method of the maintenance door 2 is not limited to the hinged flip type shown in the figure; it can also be a sliding rail type, a magnetic cover, or a quick-release panel, etc., as long as it can achieve the periodic opening and closing of the internal maintenance area, it conforms to the technical concept of this embodiment. Through the coordinated operation of the insertion hole 4, the fixing bracket 12 and the inspection door 2, this embodiment ensures the heat dissipation and torsional resistance of the core support while giving the equipment excellent assemblability and full life cycle maintainability, laying a solid structural foundation for the stable installation of the electrical cabinet body in subsequent system-level embodiments.

[0033] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
