Description

Technical Field

[0001] This utility model relates to a ventilation and heat dissipation device, specifically a box-type substation ventilation and heat dissipation device, belonging to the field of power equipment technology. Background Technology

[0002] Prefabricated substations, also known as prefabricated transformer substations, are integrated power supply devices primarily used for power supply in urban high-rise buildings, residential communities, industrial and mining enterprises, and temporary construction sites. They integrate transformers and high and low voltage distribution equipment into one or more enclosed enclosures, featuring small size and minimal footprint. Prefabricated substations can be installed outdoors or indoors as needed, facilitating rapid deployment. During operation, the internal electronic components of a prefabricated substation generate high temperatures. The ventilation and heat dissipation system uses air circulation to reduce the internal temperature of the substation, preventing damage to electrical components due to high temperatures and ensuring that the internal temperature of the substation remains within a safe range.

[0003] Most existing ventilation and heat dissipation devices for prefabricated substations use cooling fans to drive internal air to the outside, creating air circulation and providing ventilation and heat dissipation for the substation. While this structure can achieve a certain level of ventilation and heat dissipation, the cooling fan is generally installed on one side of the enclosure, with the air inlet on the bottom side. The cooling fan can only draw surrounding air outwards, rather than dissipating the air inside the enclosure evenly. The air supplied to the enclosure through the air inlet cannot be evenly distributed inside the enclosure, thus reducing the cooling effect of the prefabricated substation. Therefore, we provide a ventilation and heat dissipation device for prefabricated substations to solve the above problems. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a prefabricated substation ventilation and heat dissipation device. The specific technical solution is as follows:

[0005] A prefabricated substation ventilation and heat dissipation device includes a prefabricated enclosure and an exhaust fan. An air intake duct is connected to the inner wall of the enclosure and communicates with the outside of the enclosure. Multiple partitions are connected to the inner wall of the air intake duct and are arranged at equal intervals. A concentrator is connected to the inner wall of the enclosure and is located above the air intake duct. The exhaust fan is installed inside the concentrator. An exhaust pipe is connected to the top of the concentrator and communicates with the outside of the enclosure. A frame is connected to the outer surface of the enclosure and is located outside the exhaust pipe. A baffle is rotatably connected to the inner wall of the frame.

[0006] Preferably, a magnetic stripe one is connected to one side of the baffle, and a magnetic stripe two is connected to the inner wall of the frame, and the magnetic stripe one and the magnetic stripe two are attracted to each other by magnetic force.

[0007] Preferably, a shield is attached to the outer surface of the housing, and the shield is located above the frame.

[0008] Preferably, the inner wall of the flow-concentrating hood is connected to a support frame, and the exhaust fan is installed inside the support frame.

[0009] Preferably, a protective net is installed on the lower surface of the flow hood, and the protective net is located below the exhaust fan.

[0010] Preferably, the inner wall of the housing is connected to a support frame, and the support frame is located above the air intake duct, and the upper surface of the support frame is connected to a support grille.

[0011] Preferably, a filter screen is installed on the outer surface of the housing, and the filter screen is located outside the air intake duct.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. The ventilation and heat dissipation device of this prefabricated substation works in conjunction with the air intake duct, partitions and exhaust fan. The exhaust fan is the power source to drive the air flow and provide power for the air circulation. The partitions separate the air entering the air intake duct into multiple airflows, so that the airflow is evenly released into the box. This allows the electronic components inside the box to come into contact with the low-temperature gas, thereby improving the cooling effect of the prefabricated substation.

[0014] 2. The ventilation and heat dissipation device of this box-type substation utilizes the cooperation between magnetic strip one and magnetic strip two. When there is no air flow inside the exhaust pipe, the baffle is freely vertical. When the baffle is vertical, magnetic strip one and magnetic strip two come into contact. The magnetic force between magnetic strip one and magnetic strip two attracts them together, preventing the baffle from opening easily. When the exhaust pipe discharges air to the outside, the air blows the baffle to move its position, causing the baffle to flip. At the same time, magnetic strip one and magnetic strip two are separated. The air provides the power for the baffle to swing. The baffle acts as a shield for the exhaust pipe, preventing external dust from entering the box from the exhaust pipe and improving the cleanliness of the box. Attached Figure Description

[0021] The present invention will now be further described with reference to the accompanying drawings.

[0022] Please see Figures 1-5 A prefabricated substation ventilation and heat dissipation device includes a box body 1 and an exhaust fan 2. The inner wall of the box body 1 is connected to an air intake duct 3, which is connected to the outside of the box body 1. The inner wall of the air intake duct 3 is connected to multiple partitions 4, which are arranged at equal intervals. The air intake duct 3 guides external air into the box body 1. The partitions 4 separate the air intake duct 3 into multiple small air ducts, which extend sequentially towards the middle of the box body 1, so that the air is evenly released into the box body 1 after being guided by the small air ducts.

[0023] The inner wall of the housing 1 is connected to a flow-concentrating hood 5, and the flow-concentrating hood 5 is located above the air intake duct 3. The exhaust fan 2 is installed inside the flow-concentrating hood 5. The flow-concentrating hood 5 guides the upward-flowing air, collects the upward-flowing air together, and makes the upward-flowing air flow towards the exhaust fan 2, so that the exhaust fan 2 can discharge the air uniformly.

[0024] The top of the flow-concentrating hood 5 is connected to an exhaust pipe 6, which is connected to the outside of the housing 1. The exhaust pipe 6 discharges the air guided in by the exhaust fan 2 into the housing 1. The exhaust pipe 6 is shaped like a herringbone, with one end connected to the top of the flow-concentrating hood 5 and the other two ends located on the sides of the housing 1. A frame 7 is connected to the outer surface of the housing 1, and the frame 7 is located outside the exhaust pipe 6. A baffle 16 is rotatably connected to the inner wall of the frame 7. The frame 7 supports the baffle 16 and maintains the stability of the baffle 16. The baffle 16 seals the port of the exhaust pipe 6 to prevent external dust from entering the housing 1 from the exhaust pipe 6 when no air is being discharged to the outside. When the exhaust pipe 6 discharges air to the outside, the air pushes the baffle 16 to flip, thus preventing the outlet of the exhaust pipe 6 from being opened.

[0025] A magnetic strip 8 is connected to one side of the baffle 16, and a magnetic strip 9 is connected to the inner wall of the frame 7. The magnetic strips 8 and 9 are attracted by magnetic force and are magnetic. The magnetic strips 8 and 9 attract each other, which improves the stability of the baffle 16. When there is no air flow inside the exhaust pipe 6, the baffle 16 is perpendicular to the magnetic strips 8 and 9, and the baffle 16 will not open easily. When the exhaust pipe 6 discharges air to the outside, the air blows the baffle 16 to move its position, and at the same time, the magnetic strips 8 and 9 are separated from contact. The air provides the power for the baffle 16 to swing.

[0026] The outer surface of the housing 1 is connected to a shield 10, and the shield 10 is located above the frame 7. The shield 10 serves to shield the frame 7, preventing rainwater from contacting the frame 7 and entering the exhaust pipe 6. The shield 10 also blocks rainwater from falling to the outside, preventing rainwater from entering the exhaust pipe 6.

[0027] The inner wall of the flow hood 5 is connected to a support frame 11, and the exhaust fan 2 is installed inside the support frame 11. The support frame 11 provides support for the exhaust fan 2 and improves the stability of the exhaust fan 2.

[0028] A protective net 12 is installed on the lower surface of the flow hood 5, and the protective net 12 is located below the exhaust fan 2. The protective net 12 serves to isolate the exhaust fan 2, preventing contact with the exhaust fan 2 during operation, maintenance, and repair, thus avoiding injury to personnel and damage to the exhaust fan 2. The protective net 12 isolates the maintenance personnel from contact with the exhaust fan 2, thereby improving the safety of the maintenance personnel.

[0029] The inner wall of the housing 1 is connected to a support frame 13, and the support frame 13 is located above the air intake duct 3. The upper surface of the support frame 13 is connected to a support grille 14. The support frame 13 provides support for the support grille 14, maintaining the stability of the support grille 14. The support grille 14 provides support for the components and electronic instruments to be mounted. The holes inside the support grille 14 allow air inside the air intake duct 3 to pass through, thereby releasing the air introduced by the air intake duct 3 into the housing 1.

[0030] A filter screen 15 is installed on the outer surface of the housing 1, and the filter screen 15 is located outside the air intake duct 3. The air contains dust and impurities. After the dust and impurities enter the housing 1, they will adhere to the surface of the electronic components and reduce the heat dissipation effect of the electronic components. The filter screen 15 filters the air entering the housing 1, blocking the dust and impurities in the air outside the air intake duct 3, thereby improving the air quality entering the housing 1.

[0031] When using this utility model: First, start the exhaust fan 2. After the exhaust fan 2 rotates, it generates power and drives the air inside the housing 1 to flow to the outside. The flowing air is gathered by the concentrator 5 and flows to the position of the exhaust fan 2. Then, it is driven by the exhaust fan 2 to be discharged into the exhaust pipe 6. The air discharged into the exhaust pipe 6 blows the baffle 16 to flip. After the baffle 16 flips, it opens the exhaust pipe 6, and the air is discharged from the exhaust pipe 6 at the same time. While the air inside the housing 1 is discharged to the outside, a negative pressure is generated inside the housing 1. Then, the outside air is filtered by the filter screen 15 and enters the air intake duct 3. Then, the air is separated and guided by the partition 4 to enter the housing 1 evenly.

[0032] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without inventive effort, and these embodiments will all fall within the protection scope of the claims of this utility model.
