Description

Technical Field

[0001] This utility model relates to the field of heat dissipation technology, and more specifically, to a heat dissipation structure for an industrial control computer. Background Technology

[0002] Traditional industrial control chassis often adopt a simple side or top opening design, lacking a scientific airflow path planning, which leads to the formation of hot spots inside the chassis and uneven heat dissipation. Most industrial control chassis rely on natural convection for heat dissipation and lack an active cooling mechanism. Under high load operation, heat accumulation is easy to occur, and the internal temperature rises sharply. The arrangement of internal components does not take heat dissipation into consideration, resulting in heat source concentration, forming a heat island effect, and exacerbating local overheating problems.

[0003] The inconvenience of installing and removing the central control board is another significant problem with existing industrial control chassis. This is mainly because traditional industrial control chassis mostly use screw fixing, which requires the use of tools for multi-point fixing. The operation is cumbersome and time-consuming. Removing the central control board usually requires removing multiple connecting cables, then removing the fixing screws, and finally carefully taking it out. The whole process involves many steps. Correctly installing the central control board requires professional knowledge and experience, which is difficult for ordinary operators to complete independently, increasing maintenance costs. During frequent disassembly and assembly, various connectors and plugs are easily damaged, reducing system reliability. Utility Model Content

The housing heat dissipation mechanism includes a flip cover and a central control box. The flip cover is rotatably mounted on one end of the central control box. The flip cover has heat dissipation holes and a cooling fan is installed on it, communicating with the heat dissipation holes. A central control board is installed inside the central control box. The central control loading and unloading mechanism includes a support tube and a fixed clamping rod. A clamping tube is rotatably mounted on one end of the support tube. A tension spring rod is installed on the outer wall of the fixed clamping rod. An inner rotating frame is installed on the inner wall of the clamping tube, and a sealing frame is installed at the bottom end of the inner rotating frame.

A pressure ring is installed on the outer wall of the clamping tube, and a push plate is longitudinally mounted on the outer wall of the support tube. The push plate can press the pressure ring by moving upward.

[0008] The present invention is further configured such that the pressing mechanism includes an outer rotating ring and an outer rotating plate. A positioning spring is laterally slidably installed on the outer wall of the support tube, and multiple sets of positioning springs are arranged in a ring on the outer wall of the support tube. The outer rotating ring is rotatably positioned on the outer wall of the support tube. Multiple sets of outer rotating plates are installed at the bottom end of the outer rotating ring. Positioning holes are provided on the outer rotating plates. Different positioning springs can be inserted into the positioning holes one by one, so that the outer rotating ring rotates stably on the outer wall of the support tube. A rotary push plate is installed at the top end of the outer rotating ring. The rotation of the rotary push plate causes the push plate to move longitudinally and press the pressure ring, so that the clamping tube is fixed on the support tube.

[0009] The present invention is further provided that cable channels are provided on both sides of the central control box, through which cables are introduced into or led out of the central control box. The cable channels are provided on both sides of the central control box to facilitate the orderly introduction and exit of cables and improve the neatness of the installation.

[0010] The present invention is further configured such that a support is installed on the bottom surface of the central control box, and the fixed locking rod is connected to the support. The push-out spring on the outer wall is easy to disassemble, thereby improving the ease of operation.

[0011] The present invention is further configured such that the support is set at a fixed height, so that the central control plate and the bottom end face of the central control box have a fixed space. The support is installed at the bottom of the central control box. The fixed height design ensures that the central control plate and the bottom of the box have an appropriate space to facilitate air circulation.

[0012] The present invention is further configured such that a connecting plate is installed at the bottom end of the support tube, and the connecting plate is fixedly installed on the central control plate. The support tube can be fitted with a locking rod, and the connecting plate is installed at the bottom of the support tube and fixed on the central control plate, thereby enhancing the installation stability.

[0013] The present invention is further configured such that a slot is provided on the inner wall of the carding tube, and the sealing frame can push one end of the tension spring rod into the slot. The tension spring rod is installed on the outer wall of the fixed carding rod to achieve lateral extension and contraction, and cooperates with the slot to form a locking mechanism.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a heat dissipation structure for an industrial control computer, which has the following beneficial effects:

[0017] This utility model is equipped with a heat dissipation mechanism for the enclosure. The heat dissipation mechanism adopts a flip-top design, which facilitates maintenance and repair of internal components. The heat dissipation holes on the flip-top and the installed cooling fan form a forced convection heat dissipation system, which significantly improves heat dissipation efficiency and solves the problem of poor heat dissipation in traditional industrial control computer enclosures. This allows heat to be quickly dissipated and prevents excessive internal temperature from affecting the stability of the equipment.

[0018] This utility model is equipped with a central control loading and unloading mechanism. Through the design of the support tube and the fixed clamp rod, the central control board can be quickly installed and disassembled. The cooperation between the tension spring rod and the slot forms a locking mechanism. The inner rotating frame controls the locking process, and the push-out spring facilitates disassembly. This significantly improves maintenance efficiency and solves the problem of inconvenient installation and disassembly of the central control board of traditional industrial control computers. No tools are required, simplifying the maintenance process.

[0019] This utility model is equipped with a clamping mechanism. The clamping mechanism achieves secondary locking of the central control loading and unloading mechanism through the design of the outer rotating ring and the outer rotating plate. The positioning springs arranged in multiple rings cooperate with the positioning holes to ensure the stable rotation of the outer rotating ring. The rotating push plate converts the rotational force into longitudinal thrust, clamping the pressure ring and making the clamping pipe firmly fixed on the support pipe. The multiple locking design enhances the installation stability of the central control board and prevents the central control board from loosening due to vibration during the operation of the industrial control computer.

[0029] Please see Figures 1-5 A heat dissipation structure for an industrial control computer includes a housing heat dissipation mechanism, a central control loading and unloading mechanism, and a clamping mechanism. The housing heat dissipation mechanism includes a flip cover 1 and a central control box 2. The flip cover 1 is rotatably mounted on one end of the central control box 2. The flip cover 1 has heat dissipation holes 3 and a cooling fan 4 is installed on the flip cover 1. The cooling fan 4 is connected to the heat dissipation holes 3. A central control plate 5 is installed inside the central control box 2. The central control loading and unloading mechanism includes a support tube 6 and a fixed clamping rod 7. A clamping tube 8 is rotatably mounted on one end of the support tube 6. A tension spring rod 9 is installed on the outer wall of the fixed clamping rod 7. An inner rotating frame 10 is installed on the inner wall of the clamping tube 8, and a sealing frame 11 is installed at the bottom end of the inner rotating frame 10. The sealing frame 11 can push the tension spring rod 9 to move laterally, so that the tension spring rod 9 extends into the inner wall of the clamping tube 8. A pressure ring 12 is installed on the outer wall of the clamping tube 8. A push plate 13 is longitudinally installed on the outer wall of the support tube 6. The push plate 13 can move upward to clamp the pressure ring 12.

[0030] In this embodiment, the heat dissipation mechanism of the enclosure mainly consists of a flip cover 1 and a central control box 2. The flip cover 1 is rotatably mounted on one end of the central control box 2 and can be opened or closed. The flip cover 1 has heat dissipation holes 3 and is equipped with a cooling fan 4. When the industrial control computer generates heat during operation, the cooling fan 4 starts, dissipating the heat outside the central control box 2 through the heat dissipation holes 3, creating airflow and carrying away the heat generated by the central control board 5, thus maintaining the temperature inside the central control box 2 within a suitable range. Simultaneously, the rotatable design of the flip cover 1 facilitates equipment inspection and maintenance. The central control loading and unloading mechanism is supported by a support tube 6. It consists of a fixed locking rod 7 and a locking tube 8 installed at one end of the support tube 6. A tension spring rod 9 is installed on the outer wall of the fixed locking rod 7. When it is necessary to fix the central control plate 5, the fixed locking rod 7 is inserted into the support tube 6. The inner rotating frame 10 inside the locking tube 8 rotates, and the bottom sealing frame 11 pushes the tension spring rod 9 to move laterally, so that the tension spring rod 9 extends into the locking groove 22 on the inner wall of the locking tube 8, thereby realizing the locking connection between the fixed locking rod 7 and the locking tube 8. This makes the installation and removal of the central control plate 5 simple and convenient. No additional tools are required. Locking or unlocking can be completed simply by rotating the inner rotating frame 10.

[0031] The clamping mechanism includes an outer rotating ring 14 and an outer rotating plate 15. A positioning spring 16 is laterally slidably installed on the outer wall of the support tube 6, and the positioning spring 16 is arranged in multiple rings on the outer wall of the support tube 6. The outer rotating ring 14 is arranged to rotate at the upper limit on the outer wall of the support tube 6. Multiple sets of outer rotating plates 15 are installed at the bottom end of the outer rotating ring 14. The outer rotating plate 15 is provided with a positioning hole 17. Different positioning springs 16 can be inserted into the positioning hole 17 step by step, so that the outer rotating ring 14 rotates stably on the outer wall of the support tube 6. A rotary push plate 18 is installed at the top end of the outer rotating ring 14. The rotation of the rotary push plate 18 causes the push plate 13 to move longitudinally and press the pressure ring 12, so that the clamping tube 8 is fixed on the support tube 6.

[0032] When the clamping mechanism is in operation, multiple sets of annular positioning springs 16 are horizontally slidably installed on the outer wall of the support tube 6. The outer rotating ring 14 is limited to rotating on the outer wall of the support tube 6. The outer rotating plate 15 installed at the bottom of the outer rotating ring 14 has a positioning hole 17, which can be fitted with different positioning springs 16 to ensure the stable rotation of the outer rotating ring 14. When the outer rotating ring 14 is rotated, the top rotating push plate 18 drives the push plate 13 to move longitudinally, pressing the pressure ring 12 and fixing the clamping pipe 8 on the support tube 6. The multiple locking design enhances the stability of the central control plate 5 installation and prevents the central control plate 5 from loosening due to vibration during the operation of the industrial control computer.

[0033] Please see Figures 1-5As a supplementary implementation of the heat dissipation structure for an industrial control computer, which includes a heat dissipation mechanism for the housing, a central control loading and unloading mechanism, and a clamping mechanism: Cable grooves 19 are provided on both sides of the central control box 2, through which cables are introduced into or out of the central control box 2. A support 20 is installed on the bottom surface of the central control box 2, and a fixed clamping rod 7 is connected to the support 20. The support 20 is set at a fixed height, so that the central control plate 5 and the bottom surface of the central control box 2 have a fixed space. A connecting plate 21 is installed at the bottom end of the support tube 6, and the connecting plate 21 is fixedly installed on the central control plate 5. The support tube 6 can fit the fixed clamping rod 7 into the connection. A groove 22 is provided on the inner wall of the clamping tube 8, and the sealing frame 11 can push one end of the tension spring rod 9 into the groove 22. An inner retaining ring 23 is installed on the inner wall of the support tube 6, and a push-out spring 24 is installed on the outer wall of the fixed clamping rod 7.

[0034] More specifically, the central control plate 5 is installed on the support 20 inside the central control box 2, so that the central control plate 5 and the bottom of the central control box 2 maintain a certain amount of space to facilitate heat dissipation. The connecting plate 21 at the bottom of the support tube 6 is fixed on the central control plate 5. The fixed locking rod 7 passes through the support 20 and connects to the support tube 6. The inner rotating frame 10 inside the locking tube 8 is rotated so that the sealing frame 11 pushes the tension spring rod 9 into the slot 22 to achieve initial locking. The outer rotating ring 14 is rotated so that the rotating push plate 18 pushes the push plate 13 to move upward and presses the pressure ring 12 to form a secondary lock, ensuring that the central control plate 5 is firmly fixed. When the industrial control computer is working, the cooling fan 4 on the flip cover 1 dissipates heat through the cooling hole 3 to keep the temperature inside the central control box 2 suitable.

[0035] In summary, when the overall equipment is in use or operation: when the heat dissipation mechanism of the enclosure is required to operate, the heat dissipation mechanism of the enclosure mainly consists of a flip cover 1 and a central control box 2. The flip cover 1 is rotatably installed at one end of the central control box 2 and can be opened or closed. The flip cover 1 has heat dissipation holes 3 and is equipped with a cooling fan 4. When the industrial control computer generates heat, the cooling fan 4 starts and exhausts the heat out of the central control box 2 through the heat dissipation holes 3, forming airflow and carrying away the heat generated by the central control board 5, keeping the temperature inside the central control box 2 within a suitable range. At the same time, the rotatable design of the flip cover 1 facilitates the inspection and maintenance of the equipment.

[0036] When the central control loading and unloading mechanism is in operation, it consists of a support tube 6 and a fixed locking rod 7. One end of the support tube 6 is fitted with a locking tube 8, and the outer wall of the fixed locking rod 7 is fitted with a tension spring rod 9. When it is necessary to fix the central control plate 5, the fixed locking rod 7 is inserted into the support tube 6, the inner rotating frame 10 inside the locking tube 8 rotates, and the bottom sealing frame 11 pushes the tension spring rod 9 to move laterally, so that the tension spring rod 9 extends into the locking groove 22 on the inner wall of the locking tube 8, thereby achieving a locking connection between the fixed locking rod 7 and the locking tube 8. This makes the installation and removal of the central control plate 5 simple and convenient, without the need for additional tools. Locking or unlocking can be completed simply by rotating the inner rotating frame 10.

[0037] When the clamping mechanism is in operation, multiple sets of annular positioning springs 16 are horizontally slidably installed on the outer wall of the support tube 6. The outer rotating ring 14 is limited to rotating on the outer wall of the support tube 6. The outer rotating plate 15 installed at the bottom of the outer rotating ring 14 has a positioning hole 17, which can be fitted with different positioning springs 16 to ensure the stable rotation of the outer rotating ring 14. When the outer rotating ring 14 is rotated, the top rotating push plate 18 drives the push plate 13 to move longitudinally, pressing the pressure ring 12 and fixing the clamping pipe 8 on the support tube 6. The multiple locking design enhances the stability of the central control plate 5 installation and prevents the central control plate 5 from loosening due to vibration during the operation of the industrial control computer.

[0038] The central control plate 5 is installed on the support 20 inside the central control box 2, so that the central control plate 5 and the bottom of the central control box 2 maintain a certain space for heat dissipation. The connecting plate 21 at the bottom of the support tube 6 is fixed on the central control plate 5. The fixed locking rod 7 passes through the support 20 and connects to the support tube 6. The inner rotating frame 10 inside the locking tube 8 is rotated so that the sealing frame 11 pushes the tension spring rod 9 into the locking groove 22 to achieve initial locking. The outer rotating ring 14 is rotated so that the rotating push plate 18 pushes the push plate 13 to move upward and presses the pressure ring 12 to form a secondary lock, ensuring that the central control plate 5 is firmly fixed. When the industrial control computer is working, the cooling fan 4 on the flip cover 1 dissipates heat through the cooling hole 3 to keep the temperature inside the central control box 2 suitable.
