[0015] In order to better understand the technical solution of the present application, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0016] Reference Figure 2-Figure 4 An OPS computer includes a heat dissipation duct assembly 1 connecting the air environment inside and outside the computer box and a temperature control module 2 plugged into the circuit board. The heat dissipation duct assembly 1 includes an external tube 11, an internal tube 12, a universal tube 13, a blade 14, a blade pusher 15, a driving member 16, a micro cooling fan 17 and a cross bar 18. There are two external tubes 11, which are parallel to each other and fixed vertically on the side cover of the machine box with various plug connectors. One end of the external tube 11 is located inside the machine box, and the other end is located outside the machine box. The end located inside the machine box is longer, and the end located outside the machine box is longer. The external tube 11 connects the air environment inside and outside the machine box, and a dustproof net is fixed inside the end of the external tube 11 located outside the machine box to prevent external dust from entering the machine box. There is a distance between the two external tubes 11, and a crossbar 18 is fixed vertically between the two external tubes 11. The crossbar 18 and the two external tubes 11 form a handle for the machine box, making it convenient for users to pick up the machine box. Each external tube 11 is detachably connected to a universal tube 13 at one end of the machine box. The universal tube 13 and the external tube 11 can be connected by a threaded connection ring. The universal tube 13 is a flexible corrugated tube structure, which can be freely bent in the limited environment inside the machine box. Each end of the universal tube 13, which is away from the external tube 11, is detachably connected to the internal tube 12. The internal tube 12 and the universal tube 13 can be connected by a threaded connection ring. Each end of the internal tube 12, which is away from the universal tube 13, is equipped with a flared blade 14, a blade pusher 15, a drive member 16, and a micro cooling fan 17.

[0017] Reference Figure 5-Figure 7As shown, the expansion blade 14 is located at the end of the built-in tube 12 away from the universal tube 13. The expansion blade 14 is provided with multiple pieces and arranged circumferentially along the end of the built-in tube 12. The multiple expansion blades 14 can be expanded outward or retracted inward under the push of the blade pusher 15 to adjust the cross-sectional area of the air duct. A core column 121 is coaxially arranged in the built-in tube 12. One end of the core column 121 extends out of the end of the built-in tube 12 away from the universal tube 13, and the other end is located in the universal tube 13. A plurality of slide grooves 1211 corresponding to each expansion blade 14 are provided on the outer circumference of the core column 121. The length direction of the slide groove 1211 is consistent with the length direction of the core column 121. The end face of the core column 121 at one end of the built-in tube 12 is penetrated by the slide groove 1211, and the other end is in a non-penetrating state. A blade pusher 15 is provided in each slide groove 1211, and the blade pusher 15 is arranged between the core column 121 and the expansion blade 14.

[0018] The blade pusher 15 includes a push rod 151 , a connecting rod 152 and a connecting post 153 . The push rod 151 is slidably arranged in the slide groove 1211; there are three connecting rods 152 and all are located at the end of the push rod 151 close to the expansion blade 14. The three connecting rods 152 are hinged to each other at the head and tail, and the connecting rods 152 at both ends are hinged to the push rod 151. A groove 1511 for the hinge of the connecting rod 152 is opened on the push rod 151. The groove 1511 passes through the end face of the push rod 151 close to the expansion blade 14, and can make the connecting rod 152 close to the outside hit the inner cavity end face of the slide groove 1211, and a parallelogram is formed between the three connecting rods 152 and the push rod 151; the connecting column 153 is connected between the connecting rod 152 parallel to the push rod 151 and the inner wall of the expansion blade 14, and connecting columns 153 are provided at both ends of the connecting rod 152 parallel to the push rod 151 to ensure the connection stability between the expansion blade 14 and the connecting rod 152. As a result, the push rod 151 is pushed toward the outside of the built-in tube 12, and the push rod 151 will cause the parallelogram mechanism to move outward. When the outer connecting rod 152 hits the inner cavity end face of the slide groove 1211, the parallelogram mechanism will be deformed, and the distance between the push rod 151 and the connecting rod 152 parallel to it will gradually increase, so that the expansion blades 14 are expanded outward under the push of the blade pushing member 15. When the push rod 151 moves toward the inner cavity of the built-in tube 12, the distance between the push rod 151 and the connecting rod 152 parallel to it will gradually decrease, so that the expansion blades 14 are retracted inward under the push of the blade pushing member 15. When it is necessary to implement multiple expansion blades 14 to adjust the cross-sectional area of the air duct, they can be installed at the same time first. Step by step, push the push rods 151 that are distributed at intervals to realize the outward expansion or inward contraction of some of the expanding blades 14, and then synchronously push the remaining push rods 151 that are distributed at intervals to realize the outward expansion or inward contraction of the remaining expanding blades 14. In this way, interference between several expanding blades 14 when expanding or contracting can be avoided. The specific pushing is implemented by the driving member 16. In order to realize the pushing of two batches of push rods 151 distributed at intervals, the driving member 16 includes a driving group 161 and a driving group 162. The driving group 161 is used to control the synchronous expansion and closure of the expanding blades 14 distributed at intervals, and the driving group 162 is used to control the synchronous expansion and closure of the remaining expanding blades 14 distributed at intervals.

[0019] Reference Figure 7 and Figure 8, a driving group 161 includes a driving rod 1611, a fixed ring 1612, a movable ring 1613, a spring 1614, a pull rope 1615, and a rope-collecting screw 1616. The driving rod 1611 is fixed to the end of the push rod 151 away from the end of the expansion blade 14. There are multiple driving rods 1611 and they are distributed at intervals on each push rod 151; the fixed ring 1612 is fixed to the inner wall of the built-in tube 12 and is located at the end of the driving rod 1611 close to the push rod 151. Each driving rod 1611 is located in the fixed ring 1612, and the core column 121 is fixedly connected to the inner wall of the built-in tube 12 through the fixed ring 1612. Therefore, the fixed ring 1612 can serve as a radial support point for the core column 121; the movable ring 1613 is located at the end of the driving rod 1611 away from the push rod 151. The movable ring 1613 is used to connect each driving rod 1611; spring 1614 is fixedly connected between the fixed ring 1612 and the movable ring 1613, and spring 1614 always gives elastic force to the movable ring 1613 in the direction of the fixed ring 1612; one end of the pull rope 1615 is fixed on the movable ring 1613, and the other end passes through the universal tube 13 and is located in the external tube 11; the rope-collecting screw 1616 is rotatably set on the external tube 11 outside the machine box, the pull rope 1615 is wound around the rope-collecting screw 1616, and the movable ring 1613 forms a traction relationship with the rope-collecting screw 1616 through the pull rope 1615, and the rope-collecting screw 1616 is driven to rotate by a micro motor, and the micro motor is controlled by the temperature control module 2.

[0020] The core transmission chain that drives a group 161 is the tail end of the push rod 151 → driving rod 1611 → moving ring 1613 → pull rope 1615 → rope-collecting screw 1616. The fixed ring 1612 serves as the reference fixed point of the entire transmission chain. When the temperature control module 2 sends a control signal, the micro motor drives the rope-collecting screw 1616 to rotate. The rope-collecting screw 1616 rotates to tighten the rope 1615. The rope 1615 pulls the moving ring 1613 to overcome the elastic force of the spring 1614. The moving ring 1613 drives all connected driving rods 1611 to move synchronously and move toward the inner cavity side of the built-in tube 12, driving Rod 1611 pulls the push rod 151 to slide in the slide groove 1211. When the push rod 151 moves toward the inner cavity of the built-in tube 12, the distance between the push rod 151 and the connecting rod 152 parallel to it gradually becomes smaller, so that the opening blade 14 is retracted inward under the push of the leaf pushing member 15. When the temperature control module 2 stops the motor power supply, the rebound force of spring 1614 resets the moving ring 1613, driving the entire transmission chain to move in the opposite direction, and the push rod 151 moves toward the outside of the built-in tube 12. The distance between the push rod 151 and the connecting rod 152 parallel to it gradually becomes larger, so that the opening blade 14 is expanded outward under the push of the leaf pushing member 15.

[0021] The second drive group 162 includes a second drive rod 1621, a connecting block 1622, an internal plate 1623, a second spring 1624, a second pull rope 1625, and a second rope-collecting screw 1626. The second drive rod 1621 is coaxially arranged in the movable ring 1613; the connecting block 1622 is used to connect the push rod 151 between two adjacent first drive rods 1611 to the second drive rod 1621. The second drive rod 1621 establishes a connection with the push rod 151 through the connecting block 1622; the core column 121 is hollow, and the internal plate 1623 is fixed in the inner cavity of the core column 121. The internal plate 1623 serves as a fixed support for the second spring 1624; the second spring 1624 is fixed to the internal plate 1623 and Between the end faces of the driving rod 2 1621, and the spring 2 1624 always gives the driving rod 2 1621 an elastic force toward the core column 121; one end of the pull rope 2 1625 is fixed on the driving rod 2 1621, and the other end passes through the universal tube 13 and is located in the external tube 11; the rope-collecting screw 2 1626 is rotatably set on the external tube 11 outside the machine box, and the pull rope 2 1625 is wound around the rope-collecting screw 2 1626, and the rope-collecting screw 2 1626 is driven to rotate by a micro motor, and the micro motor is controlled by the temperature control module 2.

[0022] The core transmission chain of the second drive group 162 is push rod 151 → connecting block 1622 → drive rod 1621 → pull rope 1625 → rope collection screw 1626. The built-in plate 1623 serves as the reference fixed point of the entire transmission system. When the temperature control module 2 sends a control signal, the micro motor drives the rope collection screw 1626 to rotate. The rope collection screw 1626 rotates to tighten the rope 1625. The rope 1625 pulls the drive rod 1621 to overcome the elastic force of the spring 1624. The drive rod 1621 drives the push rod 151 to move through the connecting block 1622. The drive rod 1621 pulls the The connected push rod 151 slides in the slide groove 1211. When the push rod 151 moves toward the inner cavity of the built-in tube 12, the distance between the push rod 151 and the connecting rod 152 parallel to it gradually becomes smaller, so that the opening blades 14 are retracted inwardly under the push of the leaf pushing member 15. When the temperature control module 2 stops the motor power supply, the rebound force of the spring 2 1624 resets the moving ring 1613, driving the entire transmission chain to move in the opposite direction, and the push rod 151 moves toward the outside of the built-in tube 12. The distance between the push rod 151 and the connecting rod 152 parallel to it gradually becomes larger, so that the opening blades 14 are expanded outwardly under the push of the leaf pushing member 15.

[0023] As a result, drive group 161 and drive group 2 162 can be independently controlled by their respective micromotors, enabling the push of two spaced-apart groups of push rods 151 and preventing interference between the multiple blades 14 during expansion or contraction. Furthermore, temperature control module 2 is used to precisely control the expansion angles of the blades 14 corresponding to drive group 161 and drive group 2 162. This coordinated operation achieves more optimized heat dissipation duct control, forming a complete blade control system capable of precisely adjusting the blade state according to heat dissipation requirements.

[0024] Reference Figure 4 and Figure 5 A micro cooling fan 17 is fixed to the end of the core column 121 away from the universal tube 13. The fixing method can be that the middle position of the micro cooling fan 17 is adhered to the end surface of the core column 121, and the micro cooling fan 17 is controlled to start and stop by the temperature control module 2. In addition, a waist-shaped hole 1531 is opened on the connecting column 153, which is used to fix the micro cooling fan 17. The micro cooling fan 17 can be fixed to the end of the core column 121 or to the connecting column 153. However, when the micro cooling fan 17 is fixed to the connecting column 153, the expanded blades 14 are always in the expanded state and cannot be retracted. The fixing method of the micro cooling fan 17 can be selected according to practical conditions. Using four connecting columns 153 to fix the micro cooling fan 17 can achieve four-point fixation, which is more stable.

[0025] The temperature control module 2 monitors the internal temperature of the box in real time. When the temperature exceeds a threshold, the fan is started to generate an axial airflow, which is directed to the built-in tube 12 through the unfolded blades 14 .

[0026] This application can explain its functional principles through the following operation methods: A pair of parallel external tubes 11 run through the side cover of the chassis, also serving as handles. A dust screen is installed at the outer end of the external tube 11, and the inner end is connected to the internal tube 12 via a universal tube 13, forming a directionally adjustable heat dissipation duct. The internal tube 12, equipped with a micro cooling fan 17, can be moved to any position requiring significant heat dissipation. Multiple blades are arranged circumferentially around the end of the internal tube 12, with a dual-group drive mechanism controlling their expansion or contraction to adjust the cross-sectional area of the duct. A temperature feedback closed-loop controls the blade opening and closing, as well as the fan start and stop, to balance heat dissipation efficiency and energy consumption. This achieves a coordinated system of independently driven blades in groups, a flexible duct structure, and a temperature control module 2, achieving high-precision heat dissipation regulation while integrating the practical functionality of the chassis handle with spatial adaptability.

Thus, if these modifications and variations of this application fall within the scope of the claims of this application and their equivalents, this application is intended to include these modifications and variations.

[0028] The above is only a preferred specific implementation method of the embodiment of the present application, but the scope of protection of the present application is not limited thereto.
