Description

Technical Field

[0001] This utility model relates to a multi-layer protective heat dissipation type power distribution cabinet shell. Background Technology

[0002] Distribution cabinets are key equipment in power systems used for power distribution, housing various power distribution components. Explosion-proof distribution cabinets are a special type of distribution cabinet designed specifically for flammable and explosive environments. They are used for power distribution and circuit control, effectively isolating electrical sparks and arcs from external hazardous environments. They are mainly suitable for locations with explosive gases or dust, such as petroleum, chemical, mining, and pharmaceutical industries.

[0003] Existing power distribution cabinets are usually single-layer structures, with only a single shell separating the inside and outside, resulting in poor heat dissipation. To achieve better heat dissipation, fixed air conditioners are usually installed. Although this type of installation has a better cooling effect, it is costly, consumes a lot of energy, and is inconvenient to repair if it is damaged. Utility Model Content

[0018] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] Please see Figure 1 As shown, the embodiments of this utility model include:

[0020] A multi-layer protective heat dissipation distribution cabinet shell includes a distribution cabinet shell 1, a controller 2, a temperature sensor 3, an isolation plate 4, and a blower assembly.

[0021] The power distribution cabinet housing 1 has an air vent 5 on its side wall and a circulating air vent 6 on its top for circulating airflow.

[0022] The air vents 5 are provided in multiple sets to improve airflow efficiency and achieve air-cooling heat dissipation under normal conditions.

[0023] The inner side of the power distribution cabinet housing 1 is equipped with filters 7 at the air vent 5 and the circulating air vent 6 to prevent dust from entering.

[0024] The filter screen 7 is installed at both ends by right-angle positioning blocks 8 fixed to the inner wall of the power distribution cabinet housing 1, which facilitates the installation and removal of the filter screen 7 and makes maintenance convenient.

[0025] The top of the outer side of the power distribution cabinet housing 1 is provided with a top cover 9, which is used to shield the top and prevent rainwater from entering.

[0026] The controller 2 is located on the outer wall of the power distribution cabinet housing 1 and is used for setting the settings and parameters of the entire control system.

[0027] The temperature sensor 3 is installed on the inner wall of the power distribution cabinet housing 1 to sense the internal working temperature in real time and to feed back to the controller 2 when the set temperature is reached so as to carry out air cooling.

[0028] The power distribution cabinet housing 1 is also provided with an isolation plate 4 at intervals on one side of the air vent 5 to form a heat dissipation cavity 10, which can be used for isolation and heat dissipation of high temperature inside the power distribution cabinet.

[0029] The top and bottom of the power distribution cabinet housing 1 are flush with the recessed slots 11. The top and bottom of the isolation plate 4 are respectively provided with positioning blocks 12 that are inserted into the slots 11 to facilitate the installation and removal of the isolation plate 4 for easy maintenance in the future.

[0030] The isolation plate 4 has a ventilation opening 13 at the same level as the air guide 5, which is used to guide airflow between the inside and outside under normal conditions.

[0031] The ventilation openings 13 are provided in multiple sets and correspond one-to-one with the air guides 5 to improve air guiding efficiency.

[0032] The isolation plate 4 is also movably equipped with a blower assembly corresponding to the vent 13 within the heat dissipation cavity 10. When the internal temperature is too high, the blower assembly can achieve air cooling and improve heat exchange efficiency.

[0033] Each of the aforementioned vents 13 is equipped with a blower assembly, and different numbers of blower assemblies are activated according to different temperature requirements.

[0034] The blowing assembly includes a displacement cylinder 14, a linear guide rail 15, a mounting frame 16, and a cooling fan 17.

[0035] The displacement cylinder 14 is fixed to the isolation plate 4 and vertically positioned below the vent 13. Two linear guide rails 15 are provided and arranged parallel to each other on both sides of the vent 13. The mounting frame 16 has a square structure and a cooling fan 17 is located in the middle. The mounting frame 16 is slidably mounted on the two linear guide rails 15 and its bottom is connected to the drive end of the displacement cylinder 14. Under normal conditions, the mounting frame 16 is located below the vent 13 to avoid obstructing the vent 13. When the temperature reaches the point where the blowing assembly is activated, the displacement cylinder 14 drives the mounting frame 16 to move along the linear guide rails 15. When the cooling fan 17 is located in the center of the vent 13, the displacement stops, and the cooling fan 17 starts working, blowing the high-temperature air inside to the outside and circulating it in the other air guides 5, vent 13, and circulating air vent 6 to reduce the internal temperature.

[0036] The isolation plate 4 has heat sinks 18 spaced out on one side of the heat dissipation cavity 10, which provide isolation and heat dissipation in real time.

[0037] The entire control system uses a PLC to achieve automated control.

[0038] In summary, the multi-layer protective heat dissipation distribution cabinet shell disclosed in this utility model has a simple, reasonable, and reliable structure, real-time heat dissipation and air guiding function, and multiple sets of real-time air blowing heat dissipation components in high-temperature environments, thereby improving the heat dissipation and protection of components.

[0039] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
