Description

Technical Field

[0001] This utility model relates to the field of equipment heat dissipation technology, and in particular to a heat dissipation device for chemical electrical equipment. Background Technology

[0002] Chemical electrical equipment generates heat during operation. This heat accumulates inside the equipment. If the internal components are not cooled in a timely and effective manner, it will not only affect the safe operation of the electrical components inside the control box, but may also become an ignition source for fires and explosions.

[0003] For example, Chinese utility model patent (CN213187031U) discloses a heat dissipation device for chemical electrical equipment, which describes: "It includes an electrical equipment body, a heat dissipation box is sealed and connected to the lower side of the electrical equipment body, a ventilation chamber is opened inside the heat dissipation box and communicates with the interior of the electrical equipment body, an air inlet structure is provided at one end of the heat dissipation box, an exhaust duct is provided at the other end of the heat dissipation box, and an air guide structure is provided on the lower side of the electrical equipment body for guiding the air into the interior of the electrical equipment body."

[0004] First, in the above-mentioned device, only the structure for introducing air into the main body of the electrical equipment, such as the air guide structure, is designed, but no related exhaust structure is designed. As a result, the air entering the main body of the electrical equipment will carry heat back along the original path of the air guide structure after heat dissipation. This leads to the convergence and contact of cold air and hot air, affecting the heat dissipation effect. Furthermore, the ventilation chamber and the air guide structure are almost completely open. The air volume introduced through the air intake structure is difficult to be evenly transported upwards by the baffle plate and ventilation slot alone, resulting in air leakage. The heat dissipation effect is further reduced. Therefore, this application proposes a heat dissipation device for chemical electrical equipment. Utility Model Content

Through the overall structural design, the air ducts for airflow entering the main body of the electrical equipment and the air ducts for airflow exiting the main body of the electrical equipment are independent of each other. This avoids the convergence and contact of hot and cold airflows, while further concentrating the incoming and outgoing airflow. Combined with the closed design of the T-shaped partition frame, sealing frame and air guide box, air leakage is effectively prevented and the heat dissipation effect is effectively guaranteed.

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

[0026] As described in the background art, the above-mentioned device only designs a structure for introducing airflow into the main body of the electrical equipment, such as an air guide structure, but does not design a related exhaust structure. This causes the airflow entering the main body of the electrical equipment to carry heat back along the original path of the air guide structure after heat dissipation. This leads to the cold airflow and hot airflow converging and contacting each other, affecting the heat dissipation effect. Furthermore, the ventilation chamber and the air guide structure are almost completely open. The airflow introduced through the air intake structure cannot be evenly transported upwards by the baffle plate and ventilation slot alone, resulting in airflow leakage and further reducing the heat dissipation effect.

[0027] To solve this technical problem, this utility model provides a heat dissipation device for chemical electrical equipment, which is used for heat dissipation of electrical equipment;

[0028] The device includes an electrical equipment body 1. A T-shaped partition frame 2 is fixed to the bottom of the inner side of the electrical equipment body 1. A sealing frame 3 is fixed to the bottom of the electrical equipment body 1 and outside the T-shaped partition frame 2. An air guide box 4 is fixed to the lower end of the sealing frame 3. Both the sealing frame 3 and the air guide box 4 are in contact with the T-shaped partition frame 2. An air inlet pipe 7 is fixed to one end of the air guide box 4, and an exhaust pipe 8 is fixed to the other end of the air guide box 4. A dust filter plate 5 is installed on the inner side of the T-shaped partition frame 2 and above the air inlet pipe 7. An activated carbon filter 6 is installed on the inner side of the T-shaped partition frame 2 and above the exhaust pipe 8. A first air guide fan 9 is installed on the inner side of the sealing frame 3 and below the dust filter plate 5. A second air guide fan 10 is installed on the inner side of the sealing frame 3 and below the activated carbon filter 6.

[0029] The heat dissipation device for chemical electrical equipment provided by this utility model, through the overall structural design, makes the airflow ducts entering the main body 1 of the electrical equipment and the airflow ducts exiting the main body 1 of the electrical equipment independent of each other. With the guidance of the first air guide fan 9 and the second air guide fan 10, a unidirectional airflow path is formed, avoiding the phenomenon of airflow returning along the original path. This avoids the convergence and contact of hot and cold airflows, and further concentrates the airflow force of the introduction and exhaust. With the closed design of the T-shaped partition frame 2, the sealing frame 3 and the air guide box 4, air volume leakage is effectively avoided, and the heat dissipation effect is effectively guaranteed.

[0030] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0031] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0032] Example 1:

[0033] Please refer to Figure 1-4 A heat dissipation device for chemical electrical equipment includes an electrical equipment body 1, a T-shaped partition frame 2 fixed to the bottom of the inner side of the electrical equipment body 1, the electrical equipment body 1 is enclosed by the T-shaped partition frame 2, a sealing frame 3 is fixed to the bottom of the electrical equipment body 1 and located outside the T-shaped partition frame 2, and an air guide box 4 is fixed to the lower end of the sealing frame 3. Both the sealing frame 3 and the air guide box 4 are in contact with the T-shaped partition frame 2.

[0034] To facilitate the introduction of cool air for heat dissipation into the air guide box 4, an air inlet pipe 7 is fixed at one end of the air guide box 4. To facilitate the airflow to enter the electrical equipment body 1 through the T-shaped partition 2, a dust filter plate 5 is installed on the inner side of the T-shaped partition 2 and at the upper end of the air inlet pipe 7. To exhaust the airflow, an exhaust pipe 8 is fixed at the other end of the air guide box 4, and an activated carbon filter 6 is installed on the inner side of the T-shaped partition 2 and at the upper end of the exhaust pipe 8.

The first air guide fan 9 and the second air guide fan 10 guide the airflow direction to form a unidirectional airflow path.

[0036] When the cool air for heat dissipation is introduced into the air guide box 4 through the air inlet pipe 7, and then guided upward by the first air guide fan 9, it passes through the dust filter plate 5 and enters the T-shaped partition frame 2. The dust filter plate 5 is used to filter the dust carried by the airflow. The airflow carrying heat after heat dissipation of the main body of electrical equipment 1 is guided by the second air guide fan 10 and discharged to the outside through the activated carbon filter 6 and the exhaust pipe 8.

[0037] Example 2:

[0038] The heat dissipation device for chemical electrical equipment provided in Example 1 is further optimized, specifically, as follows: Figure 1-4 As shown, since the airflow passes through the dust filter plate 5 from bottom to top, and in order to facilitate the regular cleaning of the dust adhering to the bottom of the dust filter plate 5, and to ensure uniform airflow and thus ensure heat dissipation, a hollow screw cylinder 12 is rotatably connected inside the T-shaped partition frame 2. A screw rod 13 is threadedly connected to the inner side of the hollow screw cylinder 12. A push guide seat 14 is fixed at one end of the screw rod 13 near the dust filter plate 5. A dust scraping component is provided inside the push guide seat 14.

[0039] Specifically, the scraping assembly includes a support shaft 22, the upper end of the inner side of the pusher seat 14 is rotatably connected to the support shaft 22, the outer side of the support shaft 22 is fixed with a scraping roller 23 and a third flat gear 24, the lower end of the inner side of the pusher seat 14 is fixed with a second motor 25, the output end of the second motor 25 is fixed with a fourth flat gear 26, and the fourth flat gear 26 is meshed with the third flat gear 24.

[0040] In order to facilitate the reciprocating movement of the pusher seat 14 at the lower end of the dust filter plate 5, and then use the dust scraping assembly to clean the lower end of the dust filter plate 5, a first spur gear 16 is fixed on the outer side of the hollow screw barrel 12, and a first motor 17 is fixed on the inner side of the T-shaped partition frame 2 and outside the first spur gear 16. A second spur gear 18 is fixed at the output end of the first motor 17. The second spur gear 18 is meshed with the first spur gear 16. In order to guide the movement of the pusher seat 14 and ensure its movement stability, guide posts 15 are fixed on both sides of the pusher seat 14 near the screw 13. The guide posts 15 are slidably connected to the T-shaped partition frame 2.

[0041] During the dust removal process by the dust scraping assembly, in order to collect dust, a dust collection box 27 is fixed at the bottom of the pusher seat 14 and at the lower end of the dust scraping roller 23. In order to facilitate the cleaning of dust in the dust collection box 27, support rods 28 are fixed on both sides of the dust collection box 27. A sealing plate 29 is fixed at the end of the two support rods 28 away from the dust collection box 27. The sealing plate 29 is slidably connected to the sealing frame 3.

[0042] In order to control and power this device, a control module 19, a communication module 20 and a power supply module 21 are respectively provided on the inner side of the T-shaped partition frame 2 and at the lower end of the first motor 17. All the above electrical components are electrically connected to the control module 19, the communication module 20 and the power supply module 21. The control module 19 is a conventional known device that performs control, and the existing publicly available power connection technology will not be described in detail here.

[0043] In order to avoid heat buildup on the inside of the T-shaped partition 2, a ventilation mesh plate 11 is fixed on the inside of the T-shaped partition 2 and at the lower end of the power supply module 21.

[0044] After the main body of the electrical equipment 1 has finished cooling down, when cleaning the lower end of the dust filter plate 5, the first motor 17 is started to drive the second spur gear 18 to rotate. The meshing of the second spur gear 18 and the first spur gear 16 drives the hollow screw barrel 12 to rotate. Then, the threaded connection between the hollow screw barrel 12 and the screw 13, together with the movement guidance of the guide post 15 and the pusher seat 14, drives the pusher seat 14 to move at the lower end of the dust filter plate 5. At the same time, the second motor 25 is started to drive the fourth spur gear. Rotation of gear 26 drives the support shaft 22 and the scraper roller 23 to rotate through the meshing of the fourth flat gear 26 and the third flat gear 24. The scraper roller 23 then scrapes off the dust adhering to the lower end of the dust filter screen 5. The dust collection box 27 collects the dust. After cleaning, the pusher seat 14 is moved away from the hollow screw cylinder 12, so that the sealing plate 29 moves out from the inside of the sealing frame 3, while the dust collection box 27 is located inside the sealing frame 3, which facilitates the cleaning of the dust in the dust collection box 27.
