Description

Technical Field

[0001] This utility model relates to the field of electrical cabinet technology, specifically a heat-dissipating electrical cabinet for electrical automation control. Background Technology

[0002] Electrical components inside the electrical cabinet generate a lot of heat when they are working. As the operating time increases, the temperature inside the cabinet will gradually rise. High temperature will affect the performance of electrical components, reduce their service life, and may even damage the electrical components, thereby affecting the normal operation of the entire electrical system. Therefore, a heat-dissipating electrical cabinet is needed.

[0003] For example, an existing patent (publication number: CN212910523U) discloses a heat-dissipating electrical cabinet for electrical automation control, which includes an electrical cabinet and a water tank fixedly connected to the upper end of the electrical cabinet to improve air circulation inside the cabinet and increase the contact time between hot air and cooling water, thereby further improving the heat dissipation efficiency of the cabinet.

[0004] However, the above-mentioned heat-dissipating electrical cabinet for electrical automation control has some drawbacks in actual use: Although the heat-dissipating electrical cabinet uses a serpentine tube, air pump, air outlet, air inlet, water pump outlet, and water inlet to fill the serpentine tube with water, and the external hot air comes into full contact with the water flow with the assistance of the serpentine tube and air pipe, thus reducing the temperature of the hot air, and the fan blows the cool air from the bottom to the top of the electrical cabinet to achieve heat dissipation, in long-term operation, the seals at the connection between the water pipe and the water tank may age and loosen, which may lead to slight leakage. Currently, this heat-dissipating electrical cabinet lacks a water leakage monitoring mechanism, making it difficult to detect slight water leakage in time. This can easily lead to water accumulation in the electrical cabinet and short circuits in components, which not only affects the normal operation of the equipment but may also cause safety accidents such as electrical fires.

[0005] To address these issues, we designed a heat-dissipating electrical cabinet for electrical automation control. Utility Model Content

[0006] The purpose of this utility model is to provide a heat-dissipating electrical cabinet for electrical automation control, so as to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model provides a heat-dissipating electrical cabinet for electrical automation control, including an electrical cabinet body. A cooling box is fixedly connected to the inner side wall of the electrical cabinet body. An air inlet pipe is fixedly connected to the bottom of the cooling box. The other end of the air inlet pipe passes through the side wall of the electrical cabinet body and extends to its outer side. A connecting pipe is connected to the top of the cooling box. A water tank is fixedly connected to the top of the electrical cabinet body. An inlet pipe and an outlet pipe are respectively connected to both sides of the water tank. Both the inlet pipe and the outlet pipe are covered with protective shells. The inlet end and outlet end of the cooling box are connected to the inlet pipe and the outlet pipe, respectively. A detection tube is covered on the outer side of the inlet pipe near the water tank. Copper sulfate test paper is adhered to the inner top wall of the detection tube.

[0008] Furthermore, a stopcock valve is installed at the bottom of the detection tube, and a sealing ring is connected between the detection tube and the water inlet of the water tank.

[0009] Furthermore, an air pump is embedded in the side wall of the electrical cabinet body, the air outlet of the air pump is fixedly connected to the air inlet pipe, and a water pump is fixedly connected to the bottom of the water tank.

[0010] Furthermore, a cooling pipe is installed inside the cooling box, with the air inlet end of the cooling pipe connected to the air outlet end of the air inlet pipe, and the air outlet end of the cooling pipe fixedly connected to the connecting pipe.

[0011] Furthermore, an exhaust hood is fixedly connected to the top of the electrical cabinet body, exhaust pipes are fixedly connected to both sides of the exhaust hood, and a fan is fixedly connected to the inside of the exhaust hood.

[0012] Furthermore, a collection tray is installed at an angle at the bottom of the electrical cabinet body, and a rectangular tube is fixedly connected to the outlet of the collection tray.

[0013] Furthermore, a quick-connect fitting is provided between the water inlet pipe and the water inlet end of the cooling tank.

[0014] Furthermore, the air pump inlet is connected to a filter plate via a flange.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. By installing a detection tube near the water tank end of the inlet pipe, and utilizing internal copper sulfate test paper in conjunction with a sealing ring and the drainage function of a stopcock valve, water leakage in the pipe can be monitored. Once leakage occurs, the test paper will change color as a warning. Staff can then use the stopcock valve to promptly drain the accumulated water, preventing serious malfunctions such as water accumulation or short circuits in the electrical cabinet caused by water pipe problems, thus ensuring the safe operation of the electrical cabinet. A protective shell is also installed to protect the inlet and outlet pipes from external physical impacts, reducing the risk of pipe damage.

[0017] 2. The air pump, cooling box, water pump, and supporting pipes and cooling pipes work together to cool the air entering the electrical cabinet, thereby dissipating heat from the electrical components. The collection tray collects and drains condensate, which helps to keep the internal environment of the electrical cabinet dry. The water inlet pipe and the water inlet end of the cooling box are connected by a quick-connect coupling, which combines sealing performance with convenient operation, and can quickly realize the connection and disconnection of pipes, saving operation time.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5This utility model provides a technical solution: a heat-dissipating electrical cabinet for electrical automation control, including an electrical cabinet body 1, a cooling box 9 fixedly connected to the inner side wall of the electrical cabinet body 1, an air inlet pipe 10 fixedly connected to the bottom of the cooling box 9, the other end of the air inlet pipe 10 penetrating through the side wall of the electrical cabinet body 1 and extending to its outer side, a connecting pipe 15 connected to the top of the cooling box 9, a water tank 2 fixedly connected to the top of the electrical cabinet body 1, an inlet pipe 5 and an outlet pipe 6 respectively connected to both sides of the water tank 2, a protective shell 3 covering both the inlet pipe 5 and the outlet pipe 6, the inlet end and the outlet end of the cooling box 9 being connected to the inlet pipe 5 and the outlet pipe 6 respectively, a detection tube 19 covering the end of the inlet pipe 5 near the water tank 2, the detection tube 19 being composed of two completely symmetrical parts spliced ​​together and assembled by snap fasteners, copper sulfate test paper 22 being adhered to the inner top wall of the detection tube 19, and both the protective shell 3 and the detection tube 19 being made of transparent PC plastic.

[0026] In practice, water in water tank 2 is transported to cooling tank 9 through outlet pipe 6. In cooling tank 9, water exchanges heat with air in cooling pipe 13, absorbing heat from the air and lowering its temperature. The cooled air is discharged from the outlet of cooling pipe 13 through connecting pipe 15 and enters the electrical cabinet body 1 to dissipate heat from electrical components. Then, water flows back to water tank 2 through inlet pipe 5. When water leaks at the connection between inlet pipe 5 and water tank 2, water flows into detection pipe 19. When the water level rises to the top of detection pipe 19, white copper sulfate test paper 22 changes color upon contact with water, turning the water blue. At this time, staff can detect the leak by observing the color of the water and drain the water from detection pipe 19 by using stopcock valve 21. Protective shell 3 protects inlet pipe 5 and outlet pipe 6.

[0027] See Figure 4 As shown, a stopcock valve 21 is installed at the bottom of the detection tube 19. The protective shell 3 has an opening on the side near the stopcock valve 21 to facilitate the use of the stopcock valve 21 to drain the water in the detection tube 19. A sealing ring 20 is connected between the detection tube 19 and the water inlet of the water tank 2. The sealing ring 20 is made of rubber and has a certain elasticity. It can adapt to the deformation according to the size of the gap, so that the sealing ring 20 can fill the gap between the detection tube 19 and the water inlet of the water tank 2, play a sealing role, and reduce the risk of leakage.

[0028] See Figure 2 An air pump 12 is embedded in the side wall of the electrical cabinet body 1. The rotating shaft of the air pump 12 is connected to the rotating shaft of the motor through a coupling. The air outlet of the air pump 12 is fixedly connected to the air inlet pipe 10. The air pump 12 generates sufficient pressure to draw in external air and deliver it to the cooling box 9 for cooling. A water pump 4 is fixedly connected to the bottom of the water tank 2. The water pump 4 is electrically connected to a controller. When working, it draws out the water in the water tank 2 and delivers the water to the cooling box 9 through the water outlet pipe 6 to cool the air.

[0029] See Figure 2-3 Cooling pipe 13 is installed inside cooling box 9. The air inlet of cooling pipe 13 is connected to the air outlet of air inlet pipe 10, and the air outlet of cooling pipe 13 is fixedly connected to connecting pipe 15. Inside cooling box 9, the air in cooling pipe 13 exchanges heat with circulating water, thereby reducing the air temperature.

[0030] See Figure 2 An exhaust hood 18 is fixedly connected to the top of the electrical cabinet body 1. Ventilation holes are distributed at the bottom of the exhaust hood 18 to facilitate air circulation. Exhaust pipes 7 are fixedly connected to both sides of the exhaust hood 18, and a fan 8 is fixedly connected to the inside of the exhaust hood 18. The rotation of the fan 8 accelerates the flow of hot air towards the exhaust hood 18, and the hot air can be discharged more quickly through the exhaust pipes 7, improving heat dissipation efficiency. A collection tray 16 is installed at an angle at the bottom of the electrical cabinet body 1 to collect condensate generated by the electrical cabinet body 1. Its angled design facilitates the collection and flow of condensate. A rectangular pipe 17 is fixedly connected to the outlet of the collection tray 16 to guide the condensate collected by the collection tray 16 to the outside of the electrical cabinet body 1, allowing the condensate to be discharged in a timely manner.

[0031] See Figure 2 A quick-connect connector 14, model QSL-G1 / 4-6, connects the water inlet pipe 5 and the water inlet of the cooling box 9. This quick-connect connector provides a certain degree of sealing, facilitating quick connection and disconnection between the water inlet pipe 5 and the cooling box 9, saving time and effort and improving work efficiency. The air pump 12's air inlet is connected to a filter plate 11 via a flange. This filter removes impurities from the air, such as dust and fibers, preventing blockage of the cooling pipe 13 or affecting heat exchange efficiency, and extending the service life of the electrical components inside the electrical cabinet body 1.

[0032] Working principle:

[0033] When in use, the air pump 12 is started first. The air passes through the filter plate 11 at the air inlet to filter out impurities, and then enters the air inlet pipe 10 through the air outlet of the air pump 12. Then it enters the cooling pipe 13 in the cooling box 9. The water pump 4 is started to transport the water in the water tank 2 to the cooling box 9 through the water outlet pipe 6. The water in the cooling box 9 exchanges heat with the air in the cooling pipe 13, absorbing the heat of the air and lowering the air temperature. The cooled air is discharged through the connecting pipe 15. The fan 8 is started to discharge the originally hot air to the outside of the electrical cabinet body 1 through the exhaust pipe 7, thereby reducing the temperature inside the electrical cabinet body 1.

[0034] Meanwhile, the protective shell 3 protects the inlet pipe 5 and the outlet pipe 6. When the connection between the inlet pipe 5 and the water tank 2 leaks, water will flow into the detection tube 19. When the water level rises to the top of the detection tube 19, the copper sulfate test paper 22 will change color after contacting the water and turn the water blue. At this time, the staff can detect the leak by observing the color of the water, repair the water pipe, and drain the water in the detection tube 19 by using the stopcock valve 21.

[0035] During the cooling process, condensation may occur inside the electrical cabinet body 1. This condensation will drip onto the collection tray 16 and then be discharged through the rectangular pipe 17 fixedly connected to the outlet of the collection tray 16, thus preventing condensation from accumulating inside the electrical cabinet body 1 and affecting the normal operation of electrical components.
