Technical Field
[0001] This utility model relates to the field of power distribution cabinet technology, specifically a power distribution cabinet with good heat dissipation effect. Background Technology
[0002] Power distribution cabinets are core equipment in power systems used for distributing, controlling, and protecting electrical energy. They are widely used in power distribution systems of industrial plants, commercial buildings, residential communities, and public facilities. They integrate components such as circuit breakers, disconnect switches, instrument transformers, and surge protectors. Through reasonable electrical connections, they distribute high-voltage or low-voltage electrical energy from the power source to various electrical terminals, while also realizing functions such as circuit on / off control, overload protection, short-circuit protection, and leakage protection. As the "nerve center" of the power system, the power distribution cabinet not only ensures the safe and stable transmission of electrical energy, but also enables remote monitoring, data acquisition and fault early warning through intelligent components, providing support for the intelligent management of the power system. It is an indispensable key device for modern power distribution and control. As the core control equipment of the power system, the heat dissipation effect of the power distribution cabinet is a key design feature to ensure the continuous and stable operation of the power system. At present, the heat dissipation method of power distribution cabinets is generally to use cooling fans for forced ventilation. In some cabinets used in humid environments such as underground spaces, outdoor open spaces, or coastal high-humidity areas, the cooling fans will force the external humid air into the cabinet. Moisture is easily condensed on the surface of electrical components, forming condensation, which can easily cause short circuits or leakage accidents, and cause poor contact due to corrosion of metal parts. Therefore, a power distribution cabinet with better heat dissipation effect is proposed to address the above problems. Utility Model Content
[0003] The purpose of this utility model is to provide a power distribution cabinet with good heat dissipation to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: A power distribution cabinet with good heat dissipation includes a cabinet body. A power distribution component is located inside the cabinet body. A heat dissipation component is located on the rear side of the power distribution component. A filter component is installed on the outer side of one side wall of the cabinet body. The heat dissipation component includes a heat-conducting copper pipe. The heat-conducting copper pipe is arranged in a continuous S-shape and has a circular cross-section. Both ends of the heat-conducting copper pipe penetrate adjacent side walls of the cabinet body. One end of the heat-conducting copper pipe is connected to an air inlet duct, and the other end is connected to an air outlet duct. Both the air inlet duct and the air outlet duct are fixedly connected to adjacent outer side walls of the cabinet body. The heat-conducting copper pipe is positioned between the power distribution component and the rear end of the cabinet body cavity, and the heat-conducting copper pipe and the power distribution component are in a critical proximity state.
[0005] As a further optimization of this utility model, the heat-conducting copper tube is hollow inside, and a support strip with the same direction as the heat-conducting copper tube passes through its inner cavity. Multiple moisture-absorbing structures arranged at equal intervals are sleeved on the outside of the support strip.
[0006] As a further optimization of this utility model, the moisture-absorbing structure includes a moisture-absorbing cotton block, which is fixedly connected to the support strip, and the outer surface of the moisture-absorbing cotton block is in contact with the inner surface of the heat-conducting copper pipe. Multiple ventilation slots are distributed in a circumferential array on the moisture-absorbing cotton block.
[0007] As a further optimization of this utility model, the filter assembly includes a filter box fixedly connected to the outside of the air inlet hopper, and the inner cavity of the filter box is provided with a filter screen plate inserted from the top of the filter box, the top of the filter screen plate being flush with the top of the filter box.
[0008] As a further optimization of this utility model, the filter screen plate is provided with positioning support plates symmetrically at both ends of the top. A rotating shaft passes through the center of the positioning support plate. The bottom end of the rotating shaft is movably inserted into the top of the filter screen plate, and the positioning support plate is rotatably connected to the filter screen plate through the rotating shaft.
[0009] As a further optimization of this utility model, the bottom two ends of the positioning support plate are symmetrically embedded with first magnetic blocks, and the top two ends of the filter box are symmetrically embedded with second magnetic blocks. The first magnetic blocks and the second magnetic blocks are arranged with opposite magnetic poles that correspond in position and match in specifications.
[0010] As a further optimization of this utility model, the heat dissipation component further includes a heat dissipation fan, which is fixedly installed on the outside of the filter box, and the filter box is connected to the heat dissipation fan and the air inlet hopper.
[0011] Compared with the prior art, the beneficial effects of this utility model are: In this invention, the heat dissipation components ensure effective heat dissipation for the power distribution components while preventing humid air from entering the cabinet and directly contacting the components. This avoids condensation on the surface of electrical components, thus reducing the risk of short circuits or leakage accidents. It also prevents metal parts from corroding and causing poor contact. The filter components filter the air blown into the heat-conducting copper pipe, preventing dust and impurities from entering and affecting the pipe. Attached Figure Description

[0015] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise.

[0016] Please see Figures 1-8 This utility model provides a technical solution: A power distribution cabinet with good heat dissipation includes a cabinet body 1. A power distribution component 2 is installed inside the cabinet body 1. A heat dissipation component 3 is installed on the rear side of the power distribution component 2. A filter component 4 is installed on the outer side of one side wall of the cabinet body 1. The heat dissipation component 3 includes a heat-conducting copper pipe 31. The heat-conducting copper pipe 31 is arranged in a continuous S-shaped meandering manner, and the cross-sectional shape of the heat-conducting copper pipe 31 is circular. Both ends of the heat-conducting copper pipe 31 penetrate the adjacent side wall of the cabinet body 1. One end of the heat-conducting copper pipe 31 is connected to an air inlet duct 32, and the other end of the heat-conducting copper pipe 31 is connected to an exhaust duct 33. Both the air inlet duct 32 and the exhaust duct 33 are fixedly connected to the adjacent outer side wall of the cabinet body 1. The heat-conducting copper pipe 31 is located between the power distribution component 2 and the rear end of the inner cavity of the cabinet body 1, and the heat-conducting copper pipe 31 and the power distribution component 2 are in a critical proximity state.
[0017] As a further implementation of this solution, the heat-conducting copper pipe 31 is hollow inside, and a support strip 34 with the same direction as the heat-conducting copper pipe 31 is inserted through its inner cavity. Multiple moisture-absorbing structures 35 arranged at equal intervals are sleeved on the outside of the support strip 34. In the above arrangement, the support strip 34 can support the moisture-absorbing structures 35 and make the moisture-absorbing structures 35 evenly distributed along the direction of the heat-conducting copper pipe 31.
[0018] As a further implementation of this solution, the moisture-absorbing structure 35 includes a moisture-absorbing cotton block 351, which is fixedly connected to the support strip 34. The outer surface of the moisture-absorbing cotton block 351 is in contact with the inner surface of the heat-conducting copper pipe 31. Multiple ventilation slots 352 are arranged in a circumferential array on the moisture-absorbing cotton block 351. In the above configuration, the moisture-absorbing structure 35 can absorb moisture in the air while ensuring ventilation.
[0019] As a further implementation of this solution, the filter assembly 4 includes a filter box 41 fixedly connected to the outside of the air inlet duct 32. The inner cavity of the filter box 41 is provided with a filter screen plate 42 inserted from the top of the filter box 41. The top of the filter screen plate 42 is flush with the top of the filter box 41. In the above arrangement, the filter screen plate 42 can filter the air blown into the heat-conducting copper pipe 31, and the filter screen plate 42 has the ability to be inserted and removed, which can facilitate cleaning and maintenance.
[0020] As a further implementation of this solution, the top two ends of the filter screen plate 42 are symmetrically provided with positioning support plates 43, and a rotating shaft 44 passes through the center of the positioning support plate 43. The bottom end of the rotating shaft 44 is movably inserted into the top of the filter screen plate 42, and the positioning support plate 43 is rotatably connected to the filter screen plate 42 through the rotating shaft 44. The bottom two ends of the positioning support plate 43 are symmetrically embedded with first magnetic blocks 45, and the top two ends of the filter box 41 are symmetrically embedded with second magnetic blocks 46. The first magnetic blocks 45 and the second magnetic blocks 46 are opposite magnetic poles with corresponding positions and matching specifications. The above configuration can provide the filter screen plate 42 and the filter box 41 with easy disassembly and assembly capabilities to ensure the ease of use of the filter screen plate 42.
[0021] As a further implementation of this solution, the heat dissipation component 3 also includes a heat dissipation fan 36, which is fixedly installed on the outside of the filter box 41. The filter box 41 is connected to the heat dissipation fan 36 and the air inlet duct 32. In the above configuration, the heat dissipation fan 36 can introduce outside air into the filter box 41 for filtration and introduce the filtered air into the heat-conducting copper pipe 31 for heat dissipation.
[0022] Workflow: During heat dissipation, the cooling fan 36 in the heat dissipation assembly 3 is activated. The cooling fan 36 draws outside air into the filter box 41 in the filter assembly 4. After entering the filter box 41, the air is filtered by the filter screen 42. The filter screen 42 blocks dust and impurities in the air, preventing them from entering the heat-conducting copper pipe 31 and affecting it. The filtered air is then introduced into the heat-conducting copper pipe 31 through the air inlet 32. The heat-conducting copper pipe 31 connects with the power distribution assembly. 2 is in a critical proximity state, so the heat-conducting copper pipe 31 will absorb the heat generated when the power distribution component 2 is operating. The incoming outside air will carry away the temperature of the heat-conducting copper pipe 31 and finally discharge it through the exhaust duct 33. The entire heat dissipation process can ensure the heat dissipation effect of the power distribution component 2 while preventing the outside humid air from entering the cabinet 1 and directly contacting the power distribution component 2, avoiding the condensation of water vapor on the surface of electrical components, thus making it less likely to cause short circuit or leakage accidents, and avoiding the metal parts from rusting and causing poor contact. The moisture-absorbing cotton block 351 in the moisture-absorbing structure 35 can absorb the moisture in the air in the humid environment. The ventilation slot 352 can ensure the ventilation effect. The heat-conducting copper pipe 31 will heat up after absorbing the heat of the power distribution component 2, so it can evaporate the moisture absorbed by the moisture-absorbing cotton block 351, thereby further improving the cooling effect of the heat-conducting copper pipe 31. In the filter assembly 4, the filter screen 42 is pluggable, which facilitates cleaning and maintenance. When installing the filter screen 42, it is first inserted from the top of the filter box 41. When the filter screen 42 is fully inserted into the filter box 41, its top is flush with the top of the filter box 41. Then, the positioning support plate 43 is rotated by the pivot 44 to make it perpendicular to the filter screen 42 at 90°. At this time, the first magnetic block 45 will contact and magnetically attract the second magnetic block 46, thereby providing stability to the state of the filter screen 42. The same principle applies to disassembly. After overcoming the magnetic force of the first magnetic block 45 and the second magnetic block 46, the positioning support plate 43 is rotated until the first magnetic block 45 disengages from the second magnetic block 46 and then pulled upward.
[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
