Description

Technical Field

[0001] This utility model relates to the field of wind turbine component technology, and in particular discloses a wind turbine component for a satellite communication terminal device. Background Technology

[0002] Traditional satellite communication terminal equipment's cooling fan components often employ fixed speeds or unified start-stop control. This lack of flexibility in adjusting the start / stop and speed of individual fans, or the coordinated speed control of multiple fans, based on the temperature of core components, makes it difficult to accurately match cooling demands. This can easily lead to over- or under-cooling, resulting in low cooling efficiency and energy waste. Furthermore, the assembly and disassembly of the fan brackets and terminal equipment are complex, requiring specialized tools and involving cumbersome operations, making installation and maintenance time-consuming and labor-intensive, increasing labor costs. In addition, the wires between the cooling fans and the adapter plates are easily exposed and damaged, affecting the equipment's aesthetics and safety; the fan adapter plates lack stable installation space and precise positioning, resulting in poor connection stability; the equipment's waterproof performance is insufficient, making it prone to circuit failures in humid environments; the wires lack effective cable management structures, making them prone to tangling and wear; and the fan brackets struggle to balance lightweight design with structural stability, resulting in either excessive weight or insufficient rigidity, and poor airflow guidance, failing to meet the demands of scenarios requiring high flexibility in cooling and ease of maintenance. Utility Model Content

[0003] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to provide a fan component for a satellite communication terminal device.

[0004] To achieve the above objectives, this utility model provides a fan assembly for a satellite communication terminal device, comprising a fan bracket installed on the satellite communication terminal device, multiple cooling fans arranged along the length of the fan bracket, and a fan adapter plate electrically connected to each cooling fan. The fan adapter plate is equipped with a temperature sensing module and a drive circuit. The temperature sensing module collects temperature signals from the core heat-generating components of the satellite communication terminal device, and the drive circuit independently controls the start / stop or speed adjustment of a single cooling fan based on the temperature signal, or controls multiple cooling fans to coordinately adjust their speed according to a preset gradient. The end of the fan bracket along its length is provided with a disassembly and assembly structure, allowing users to quickly assemble and disassemble the fan bracket from the terminal device.

[0005] This fan assembly, through the cooperation of a temperature sensing module and a drive circuit, can independently control the start, stop, and speed adjustment of a single fan based on the temperature of the core heat-generating components, or allow multiple fans to coordinate their speeds according to a preset gradient. This allows for precise matching of heat dissipation needs, avoiding energy waste and improving heat dissipation efficiency. Simultaneously, the detachable structure at the end of the fan bracket enables quick assembly and disassembly with terminal equipment, greatly simplifying the installation and maintenance process, saving time and labor costs. It is suitable for satellite communication terminal equipment with high requirements for heat dissipation flexibility and ease of maintenance.

[0006] Furthermore, the disassembly and assembly structure consists of disassembly and assembly screw holes located at the ends of the wind turbine bracket. Users can quickly disassemble and assemble the wind turbine bracket and the terminal equipment by screwing an external threaded pull ring into the disassembly and assembly screw holes.

[0007] The design utilizes screw holes for easy assembly and disassembly, allowing users to quickly assemble and disassemble the wind turbine bracket and terminal equipment simply by screwing in the external threaded pull ring. No complicated tools are required, making the operation simple and convenient. This structural design ensures both efficiency in the assembly and disassembly process and stability of the wind turbine bracket after installation, effectively improving the convenience of equipment maintenance, reducing maintenance difficulty, and making it suitable for quickly inspecting and replacing wind turbine components in various scenarios.

[0008] Furthermore, the temperature sensing module consists of multiple temperature sensors installed on each core heat-generating component of the satellite communication terminal equipment, and all of the multiple sensors are electrically connected to the drive circuit.

[0009] Multiple temperature sensors are installed on each core heat-generating component, enabling precise capture of real-time temperatures and providing comprehensive and detailed temperature data support for the drive circuit. The interconnection design of multiple sensors with the drive circuit avoids temperature control failure caused by a single sensor malfunction, improving the reliability of temperature monitoring. This distributed temperature measurement method allows the drive circuit to more accurately control the fan operation based on the actual heat generation of each component, ensuring that each core component receives appropriate heat dissipation. This prevents localized overheating from affecting equipment performance and avoids energy waste caused by excessive heat dissipation, significantly enhancing the targetedness and stability of heat dissipation control in satellite communication terminal equipment.

[0010] Furthermore, the fan bracket is provided with a wire shielding cover for shielding the wires between the cooling fan and the fan adapter plate. The wire shielding cover has multiple strip-shaped ventilation holes arranged along its length, and the strip-shaped ventilation holes are not connected to the airflow of the cooling fan.

[0011] The wire shield covers the wires between the cooling fan and the fan adapter plate, preventing exposed wires from being damaged or affecting the aesthetics of the equipment. The strip-shaped ventilation holes enhance airflow and improve heat dissipation. Furthermore, their design, which prevents external dust from directly entering the fan through the ventilation holes, provides a degree of protection.

[0012] Furthermore, the fan bracket is provided with a receiving groove for accommodating the fan adapter plate, an annular waterproof groove surrounding the receiving groove, and a sealing strip is arranged in the annular waterproof groove. During assembly, the sealing strip placed in the waterproof groove is squeezed to achieve waterproof sealing of the joint surface between the fan bracket and the external equipment.

[0013] The receiving groove provides a stable installation space for the fan adapter plate, ensuring its fixed position. The sealing strip inside the annular waterproof groove is compressed during assembly, effectively filling the gaps between the fan bracket and the external equipment joint surface, forming a reliable waterproof seal structure. This prevents moisture and humidity from entering the equipment, protecting the fan adapter plate and related circuit components from water damage, and improving the reliability and service life of the equipment in humid environments.

[0014] Furthermore, the wind turbine bracket is provided with a plurality of first bolt holes and a plurality of second bolt holes near the annular waterproof groove. The first bolt holes are used to screw the wind turbine adapter plate onto the wind turbine bracket, and the second bolt holes are used to screw and fix the wind turbine bracket to the satellite communication terminal equipment. The plurality of first bolt holes and the plurality of second bolt holes are arranged circumferentially around the wind turbine adapter plate.

[0015] Multiple primary bolt holes are arranged circumferentially around the fan adapter plate, evenly distributing fixing stress and preventing deformation of the adapter plate due to excessive localized stress, ensuring a stable and reliable electrical connection between it and the cooling fan. Secondary bolt holes are also arranged circumferentially, making the connection between the fan bracket and the terminal equipment more secure, effectively resisting vibration and impact during equipment operation and preventing the bracket from loosening. This design ensures the precision and stability of component assembly, provides standardized operating points for disassembly and maintenance, reduces installation deviations, improves maintenance efficiency, and enhances the overall structural strength and anti-interference capability of the fan assembly.

[0016] Furthermore, a wire harness assembly is provided between two adjacent cooling fans. The wire harness assembly has a wire harness seat and a wire harness line. Both ends of the wire harness line pass through the wire harness seat and are plugged into each other. The wires of the cooling fans are limited by the wire harness seat and the wire harness line.

[0017] The cable tie features curved connectors at both ends and open sockets at the other. This design facilitates smoother insertion and quicker assembly. The resulting retaining holes precisely accommodate the cooling fan wires, ensuring stable and secure placement. Furthermore, the curved connectors reduce wear during insertion, while the open sockets simplify the process, enhancing the practicality and durability of the cable tie assembly.

[0018] Furthermore, the cable harness holder is fixed to the fan bracket by bolts, with the bolt head corresponding to the cable harness line passing through the cable harness holder. When the two ends of the cable harness line are inserted and engaged, the bolt head and the cable harness line abut against each other.

[0019] The cable tie holder is fixed to the fan bracket with bolts, ensuring the stability of the cable tie assembly installation and preventing loosening due to equipment vibration. The bolt head abuts against the cable tie wire passing through the cable tie holder, further limiting the cable tie wire and preventing displacement during use. This ensures the continuous and reliable limiting effect on the wires and enhances the overall structural stability of the cable tie assembly.

[0020] Furthermore, the fan support between two adjacent cooling fans is provided with a hollow cavity, and reinforcing ribs are provided in the hollow cavity along the length of the fan support.

[0021] The fan support features a hollow cavity between adjacent cooling fans, which reduces overall weight while maintaining structural strength, achieving a lightweight design. The reinforcing ribs within the hollow cavity effectively enhance the support's resistance to deformation, improve structural rigidity, and ensure stable shape under long-term use or stress, providing robust support for the cooling fans and guaranteeing the normal operation of the cooling system.

[0022] Furthermore, the fan bracket has a groove-shaped structure on one side along the air delivery direction of the cooling fan.

[0023] The grooved structure on one side of the fan bracket along the airflow direction of the cooling fan guides the airflow, directing it more effectively to the areas of the equipment requiring cooling, thus improving the targeting and efficiency of heat dissipation. Simultaneously, the grooved structure can, to some extent, prevent external debris from directly entering the fan's airflow path, protecting the airflow channel, ensuring unobstructed cooling, and maintaining good heat dissipation performance.

[0024] The beneficial effects of this utility model are as follows: This fan assembly can independently control the start / stop and speed adjustment of a single fan or the coordinated speed adjustment of multiple fans based on the temperature of the core components, accurately matching heat dissipation needs, avoiding energy waste, and improving efficiency; the disassembly and assembly structure at the end of the fan bracket enables quick assembly and disassembly with the terminal equipment, simplifying installation and maintenance and saving costs. The disassembly and assembly structure uses screw holes, requiring no complex tools, making operation convenient and installation stable. Multiple temperature sensors accurately capture the temperature of each component, improving monitoring reliability and making heat dissipation control more targeted and stable. The wire shielding cover covers the wires and has strip-shaped ventilation holes, enhancing ventilation and preventing dust. The receiving groove fixes the adapter plate, and the annular waterproof groove and sealing strip achieve waterproof sealing, improving equipment reliability. The first and second bolt holes are arranged around the perimeter to ensure stable assembly, reduce deviation, and enhance structural strength. The wire harness assembly stabilizes and limits the wires, improving structural stability. The hollow cavity reduces weight, and the reinforced ribs enhance rigidity. The grooved structure guides airflow, improving heat dissipation efficiency and protecting the air path. Attached Figure Description

[0031] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0032] Please see Figures 1 to 5 As shown, a fan assembly for a satellite communication terminal device according to this utility model includes a fan bracket 1 installed on the satellite communication terminal device, multiple cooling fans 3 arranged along the length of the fan bracket 1, and a fan adapter plate 4 electrically connected to each cooling fan 3. The fan adapter plate 4 is equipped with a temperature sensing module and a drive circuit. The temperature sensing module collects the temperature signal of the core heat-generating component of the satellite communication terminal device. The drive circuit independently controls the start / stop or adjusts the speed of a single cooling fan 3 according to the temperature signal, or controls multiple cooling fans 3 to coordinately adjust their speed according to a preset gradient. The end of the fan bracket 1 along its length is provided with a disassembly and assembly structure, which allows the user to quickly disassemble and assemble the fan bracket 1 with the terminal device.

[0033] The temperature sensing module captures real-time temperature changes of the core heat-generating components of the satellite communication terminal and transmits the data to the drive circuit of the fan adapter board 4. The drive circuit flexibly adjusts based on the temperature signal: it can individually control the start / stop or speed change of a single cooling fan 3, or it can coordinate the speed adjustment of multiple fans according to a preset gradient, ensuring precise matching of heat dissipation capacity with temperature. The disassembly and assembly structure at the end of the fan bracket 1 provides convenient operation for users, allowing for quick installation or disassembly of the fan bracket 1 and the terminal equipment, facilitating maintenance and replacement. Multiple cooling fans 3 are fixed to the fan bracket 1 along its length. The fan adapter board 4 integrates the temperature sensing module and drive circuit, with the sensing probe aligned with the core heat-generating components. The preset gradient can be set according to the heat dissipation characteristics of the terminal equipment. The drive circuit has a preset 3-level speed adjustment gradient: when the temperature is ≤45℃, only fan 1 is activated (speed 1500rpm); when the temperature is 45℃-60℃, fans 1 and 2 are increased to 2000rpm; when the temperature is ≥60℃, all four fans operate synchronously at 2500rpm.

[0034] The disassembly and assembly structure can be configured using a snap-fit ​​and slot-fitting mechanism. Pressing the snap-fit ​​allows the bracket to be pulled out; during installation, align it with the slot and push it in until the snap-fit ​​returns to its original position. The entire process requires no tools and can be completed within 30 seconds. Alternatively, a sliding rail pull-out type can be used. T-shaped sliding rails are provided on both sides of the bracket, and a groove with a dustproof brush is provided at the corresponding position of the terminal equipment. A polyurethane elastic limit block is installed at the end of the groove; pressing the limit block allows the bracket to be manually pulled out and disassembled within 30 seconds. A threaded connection type can also be used. With the threaded connection type, each end of the fan bracket 1 has two M5-sized mounting and disassembly screw holes 5, 10mm deep, with coarse threads (0.8mm pitch) on the inner wall. A positioning pin is provided at the corresponding position of the terminal equipment. During installation, the bracket is initially aligned using the positioning pin, and then the matching M5 bolt with a ring handle is screwed into the screw hole and tightened until the handle is flush with the bracket surface to complete the fixation. For disassembly, the bolt is loosened by unscrewing in the opposite direction, and the bracket can be pulled out using the handle.

[0035] Specifically, the disassembly and assembly structure is a disassembly and assembly screw hole 5 located at the end of the fan bracket 1. The user can quickly disassemble and assemble the fan bracket 1 and the terminal equipment by screwing an external threaded pull ring into the disassembly and assembly screw hole 5.

[0036] The assembly and disassembly structure enables quick assembly and disassembly of the fan bracket 1 and the terminal equipment via a threaded connection. When assembly or disassembly is required, the user screws the external threaded pull ring into the assembly and disassembly screw hole 5 at the end of the fan bracket 1. After tightening, the pulling or pushing force of the pull ring is used to separate or tightly connect the fan bracket 1 and the terminal equipment. The fastening force of the thread and the leverage effect simplify the assembly and disassembly operation.

[0037] During implementation, the inner wall of the screw hole 5 is equipped with a standard thread, compatible with common threaded pull rings. The terminal equipment has corresponding positioning holes. When installing the fan bracket 1, it is first initially positioned through the positioning holes, then the pull ring is screwed in to the appropriate tightness to complete the fixation. For disassembly, tightening the pull ring creates a gap between the bracket and the equipment, allowing it to be pulled out smoothly. Compared to traditional screw fixing, this method improves disassembly and assembly efficiency by 60% and avoids the problem of lost screws.

[0038] Specifically, the temperature sensing module consists of multiple temperature sensors installed on each core heat-generating component of the satellite communication terminal equipment, and all of the sensors are electrically connected to the drive circuit.

[0039] Multiple temperature sensors are installed on the core heat-generating components of the satellite communication terminal equipment to directly monitor the temperature of each component. The temperature is converted into electrical signals (analog voltage or digital signals) and transmitted to the drive circuit. The drive circuit filters, amplifies, and performs A / D conversion on the received electrical signals through a signal conditioning module to obtain digital temperature data. The control chip comprehensively analyzes multiple sets of data to determine the real-time temperature status of each heat-generating component. Based on preset temperature thresholds and speed control logic, the drive circuit outputs corresponding control signals: when the temperature in a certain area exceeds the limit, the corresponding area's fan is individually controlled to start / stop or change speed; when the overall temperature rises, multiple fans are accelerated according to a preset gradient; if the temperature drops to a safe range, the speed is reduced or some fans are shut down. Through distributed monitoring by multiple sensors and intelligent response of the drive circuit, dynamic matching between heat dissipation capacity and equipment heating status is achieved, ensuring stable operation of the terminal equipment at a suitable temperature.

[0040] Specifically, the fan bracket 1 is provided with a wire shielding cover 2 for shielding the wires between the cooling fan 3 and the fan adapter plate 4. The wire shielding cover 2 has a plurality of strip-shaped ventilation holes 6 arranged along its length direction. The strip-shaped ventilation holes 6 are not connected to the airflow of the cooling fan 3.

[0041] The main function of the wire shielding cover 2 is to cover the wires between the cooling fan 3 and the fan adapter plate 4, preventing the wires from being exposed and damaged or affecting the airflow. The strip-shaped ventilation hole 6 is used to maintain air circulation inside and outside the bracket. At the same time, because it is not in communication with the airflow of the cooling fan 3, it avoids the airflow directly impacting the wires, reduces the aging of the wires caused by long-term airflow, and also prevents foreign objects from contacting the wires through the ventilation hole.

[0042] In practice, the wire shielding cover 2 is made of flame-retardant plastic and is fixed to the fan bracket 1 with clips, covering the area where the wires are located. Strip-shaped ventilation holes 6 are evenly distributed along the length of the cover, with the holes facing perpendicular to the airflow direction of the cooling fan 3. The holes are 5mm wide and 10mm apart. During installation, the wires are first neatly arranged inside the bracket, and then the wire shielding cover 2 is fastened to ensure that the wires are completely covered and the ventilation holes are unobstructed, thus protecting the wires without affecting overall heat dissipation.

[0043] Specifically, the fan bracket 1 is provided with a receiving groove for accommodating the fan adapter plate 4, an annular waterproof groove 7 surrounding the receiving groove, and a sealing strip is disposed in the annular waterproof groove 7. During assembly, the sealing strip placed in the waterproof groove is squeezed to achieve waterproof sealing of the joint surface between the fan bracket 1 and the external equipment.

[0044] The sealing strip inside the annular waterproof groove 7 is compressed during the assembly of the fan bracket 1 with external equipment, forming a sealing barrier to prevent moisture, dust, and other contaminants from entering from the joint surface. The receiving groove is used to fix the fan adapter plate 4, ensuring its stable position. Together with the sealing structure, it ensures that the internal circuitry of the adapter plate is not affected by the external environment and maintains normal operation.

[0045] During implementation, the dimensions of the receiving groove match those of the fan adapter plate 4, ensuring the adapter plate is placed stably. An annular waterproof groove 7, 8mm wide and 5mm deep, surrounds the edge of the receiving groove and contains a silicone rubber sealing strip resistant to high and low temperatures. During assembly, the pressing surface of the external equipment compresses the sealing strip, causing it to elastically deform and fill the waterproof groove, achieving an IP65 waterproof seal to withstand the potentially humid outdoor environment faced by satellite communication terminals.

[0046] Specifically, the wind turbine bracket 1 is provided with a plurality of first bolt holes 17 and a plurality of second bolt holes 18 near the annular waterproof groove 7. The first bolt holes 17 are used to screw the wind turbine adapter plate 4 onto the wind turbine bracket 1, and the second bolt holes 18 are used to screw and fix the wind turbine bracket 1 to the satellite communication terminal equipment. The plurality of first bolt holes 17 and the plurality of second bolt holes 18 are arranged circumferentially around the wind turbine adapter plate 4.

[0047] The first bolt hole 17 and the second bolt hole 18 on the fan bracket 1 are arranged circumferentially around the fan adapter plate 4, forming a double fixing structure. The first bolt hole 17 is used to screw the fan adapter plate 4 onto the bracket. The multiple bolts distributed circumferentially ensure that the adapter plate is evenly stressed, preventing loosening due to vibration and ensuring a stable connection between the temperature sensing module and the drive circuit. The second bolt hole 18 is used to screw the bracket onto the satellite communication terminal equipment. Similarly, the circumferentially arranged bolts ensure that the bracket and the equipment fit tightly. With the sealing strip in the annular waterproof groove 7, under the action of the bolt preload, the strip is evenly squeezed to form a complete sealing surface, preventing moisture and dust from entering. This circumferential layout around the adapter plate ensures that the fixing points correspond to the waterproof structure positions, and the bolt tightening force acts directly on the sealing area, enhancing the sealing reliability. At the same time, it ensures the relative positional stability of the adapter plate, bracket, and equipment, providing a structural foundation for wire connection and the operation of the cooling fan 3.

[0048] Specifically, a wire harness assembly is provided between two adjacent cooling fans 3. The wire harness assembly has a wire harness seat 8 and a wire harness line 9. Both ends of the wire harness line 9 pass through the wire harness seat 8 and are plugged into each other. The wires of the cooling fans 3 are limited by the wire harness seat 8 and the wire harness line 9.

[0049] The cable harness assembly uses the cable harness holder 8 and the cable harness line 9 to limit and fix the wires of the cooling fan 3. The two ends of the cable harness line 9 pass through the cable harness holder 8 and are then inserted to bind the wires within the space formed by the cable harness holder 8 and the cable harness line 9. This prevents the wires from loosening or tangling due to fan vibration or equipment movement, ensuring stable circuit connection and avoiding any impact on the operation of the cooling fan 3 due to wire problems.

[0050] In practice, the cable tie 8 is made of ABS material and fixed to the fan bracket 1 between two adjacent cooling fans 3. The cable tie line 9 is an elastic plastic strip with a length adapted to the spacing of the cable tie 8. The wires are placed in the groove of the cable tie 8, and the two ends of the cable tie line 9 are passed through the through holes of the cable tie 8 to make the two ends fit together, tightly limiting the wires. Each cable tie assembly can fix 3-5 wires. The bending radius of the wires is not less than 10mm to ensure that the insulation layer is not damaged.

[0051] Specifically, the two ends of the wire bundle 9 are respectively provided with an arc-shaped plug end 11 and an open plug end 12. The plug end 11 and the plug end 12 are plugged together to form a limiting hole for accommodating the wire of the cooling fan 3.

[0052] The plug-in end 11 and socket end 12 at both ends of the cable 9 form a limiting hole through plug-in mating, which constrains the wires of the cooling fan 3. The curved plug-in end 11 facilitates smooth insertion into the socket end 12 with an opening. The opening design allows for a certain degree of elastic deformation, making the plug-in tighter. The curvature adapts to the shape of the wire, making the limiting hole fit more firmly with the wire and preventing the wire from slipping out.

[0053] During implementation, the plug end 11 is semi-circular, with a diameter slightly smaller than the opening width of the socket end 12. The inner side of the opening of the socket end 12 has a protrusion that engages with the groove of the plug end 11 to achieve a locking action. The diameter of the limiting hole is set to 3-8mm according to the wire specification. After the wire is placed in the cable tie 8, the plug end 11 is inserted into the socket end 12 until a clicking sound is heard. At this point, the wire is stably limited and will not loosen even when subjected to a 5N pull force, and it is also convenient for subsequent wire replacement and adjustment.

[0054] Specifically, the cable tray 8 is fixed to the fan bracket 1 by bolts. The bolt head 13 corresponds to the cable tray line 9 that passes through the cable tray 8. When the two ends of the cable tray line 9 are inserted and engaged, the bolt head 13 abuts against the cable tray line 9.

[0055] The cable tie holder 8 is fixed to the fan bracket 1 by bolts to ensure the overall stability of the cable tie assembly. The bolt head 13 abuts against the cable tie line 9 that passes through the cable tie holder 8. When the two ends of the cable tie line 9 are inserted and engaged, the bolt head 13 applies pressure to the cable tie line 9 to enhance the binding force of the cable tie line 9 on the wires, prevent the cable tie line 9 from loosening, and further ensure the reliability of the wire limit.

[0056] In practice, the bottom of the cable tray 8 is provided with a screw hole, and the corresponding threaded hole is pre-set in the fan bracket 1. The two are fixed with M3 bolts, and the tightening torque is 2-3 N·m. The through hole on the cable tray 8 corresponds to the bolt head 13. When the cable bundle 9 passes through the through hole and is inserted, the bolt head 13 contacts the surface of the cable bundle 9. Tightening the bolt can adjust the pressure on the cable bundle 9, increasing the friction between the cable bundle 9 and the wire, preventing the wire from shifting in a vibration environment, and adapting to the bumpy usage scenarios of satellite communication terminals.

[0057] Specifically, the fan bracket 1 has a groove structure 16 on one side along the air supply direction of the cooling fan 3.

[0058] The grooved structure 16 on one side of the fan bracket 1 along the airflow direction of the cooling fan 3 can guide and converge the airflow, making the airflow delivered by the cooling fan 3 flow more concentratedly to the target heat dissipation area, reducing airflow diffusion loss and improving heat dissipation efficiency. At the same time, the grooved structure 16 can also enhance the structural strength of the fan bracket 1 in this direction and resist the stress caused by airflow impact.

[0059] In implementation, the trough structure 16 has a depth of 10mm and a width that matches the air outlet of the cooling fan 3. The inner wall is smoothed to reduce air resistance. The trough structure 16 maintains the same airflow direction as the cooling fan 3, with the air outlet aligned with the core heat-generating components of the terminal equipment. This allows airflow to directly reach the heat-generating points through the trough, increasing airflow utilization by 25%. Furthermore, the trough is integrally stamped, forming a unified structure with the fan bracket 1, enhancing its wind load resistance.

[0060] In this embodiment, the fan bracket 1 between two adjacent cooling fans 3 is provided with a hollow cavity, and a reinforcing rib surface 14 is provided in the hollow cavity along the length direction of the fan bracket 1.

[0061] The fan bracket 1 has a hollow cavity between two adjacent cooling fans 3 to reduce the overall weight of the bracket. At the same time, the reinforcing ribs 14 in the hollow cavity enhance the structural strength of the bracket. While reducing the weight, the bracket is prevented from deforming due to stress or vibration, ensuring the installation stability of the cooling fans 3 and ensuring that the cooling direction and air volume are not affected.

[0062] In implementation, the hollow cavity is opened along the length of the fan support 1, with a rectangular cross-section, 50mm long and 30mm wide. Reinforcing ribs 14 are spaced 10mm apart along the length of the cavity, perpendicularly connected to the cavity wall to form a grid structure, and are integrally molded from aluminum alloy. This design reduces the weight of the support by 30%, increases its bending strength by 40%, and can withstand the vibration of the cooling fan 3 during operation and the impact during transportation, ensuring the fan's positional accuracy.

[0063] In this embodiment, the inner edge of the receiving groove is provided with a positioning step 15, and the fan adapter plate 4 is attached to the outer edge of the positioning step 15 and fastened with bolts.

[0064] The positioning step 15 on the inner edge of the receiving groove provides precise installation positioning for the fan adapter plate 4, enabling the adapter plate to quickly find its position during assembly. Placing it against the outer edge of the positioning step 15 ensures accurate relative positioning between the adapter plate and the fan bracket 1. Bolt tightening further ensures the stability of the adapter plate, preventing it from shaking during equipment operation and guaranteeing reliable circuit connections.

[0065] In practice, the positioning step 15 is 2mm high and 5mm wide, matching the edge dimensions of the fan adapter plate 4. When the adapter plate is placed, its edge fits tightly against the step, with an error not exceeding 0.5mm. The bottom of the receiving groove has four bolt holes, corresponding to the mounting holes of the adapter plate. M2.5 bolts are used for fixing, with a tightening torque of 1.5-2 N·m, ensuring tight contact between the adapter plate and the bottom surface of the receiving groove, enhancing heat dissipation, and preventing bolt loosening due to vibration.

[0066] The working principle of this invention is as follows: Efficient heat dissipation and stable operation are achieved through intelligent temperature control and structural design. Multiple temperature sensors at the core heat-generating components collect temperature signals in real time and transmit them to the drive circuit of the fan adapter board 4. The drive circuit, based on preset gradient logic, individually or collaboratively controls the start / stop and speed of multiple cooling fans 3, ensuring that the heat dissipation capacity precisely matches the equipment's heating state. For example, when the temperature is below 45℃, only fan 1 is activated; when the temperature is above 60℃, all four fans operate at full speed, ensuring the equipment operates within a suitable temperature range.

[0067] The structural design of the components balances protection and convenience. The fan bracket 1 secures the adapter plate via a receiving groove, and the surrounding annular waterproof groove 7, combined with a sealing strip, forms an IP65-level waterproof seal under the force of bolt tightening, preventing moisture and dust intrusion. The wire shielding cover 2 conceals the wires and balances protection and heat dissipation through strip-shaped ventilation holes 6. The wire harness assembly secures the wires through the insertion and connection of the wire harness seat 8 and the wire harness line 9, preventing loosening and tangling caused by vibration. Meanwhile, the disassembly and assembly structure at the end of the bracket (such as a threaded connection with a pull ring) allows for rapid disassembly and assembly within 30 seconds. The circumferentially distributed bolt holes and positioning steps 15 ensure precise and stable installation of each component, while the hollow cavity and reinforcing ribs 14 reduce weight while increasing structural strength.

[0068] Airflow guidance and structural reinforcement design further enhance heat dissipation efficiency and durability. The grooved structure 16 in the air supply direction of the fan bracket 1 converges the airflow, reduces diffusion loss, and makes the airflow more concentrated on the heat-generating components, improving airflow utilization by 25%.
