Description

Technical Field

[0001] The utility model belongs to the field of electric power equipment, in particular to a power distribution cabinet which is convenient for heat dissipation and cleaning. Background Art

[0002] The power distribution cabinet is the final equipment in the power distribution system. According to its purpose, it can be divided into power distribution cabinet, lighting distribution cabinet and metering cabinet. When in use, the power distribution cabinet is usually used to distribute the power of a circuit of the upper-level distribution equipment to the nearest load, and accordingly undertakes multiple tasks such as controlling power distribution, implementing circuit protection, conducting power quality detection and performing remote control.

[0003] Since the distribution cabinet is equipped with a variety of electrical components such as circuit breakers, switches, contactors, fuses and transformers, and these electrical components will generate a lot of heat when working, common distribution cabinets are generally equipped with complex air ducts and cooling fans. When the temperature inside the distribution cabinet rises, starting the cooling fan can form airflow in the air duct, thereby reducing the temperature inside the distribution cabinet with the help of gas flow.

[0004] However, since there will inevitably be foreign matter such as dust or flying catkins in the outside air, when the cooling fan draws the outside air into the air flow channel, foreign matter will easily gather inside the complex air flow channel, causing the air flow channel to be blocked, thereby affecting the heat dissipation effect of the power distribution cabinet. To solve this problem, technicians in this field will choose to set a filter at the air inlet of the air flow channel to intercept foreign matter, but after long-term use, the filter will also be blocked, so it cannot meet the actual use needs.

[0031] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0032] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0033] A power distribution cabinet that is easy to dissipate heat and clean, the structure of which can be Figure 1-Figure 7 As shown in the figure, in this embodiment, the power distribution cabinet for easy heat dissipation and cleaning includes: a cabinet body 1, a bearing plate 3, an intercepting plate 4 and a heat dissipation fan 5, wherein the cabinet body 1 includes a guide section, a receiving section and an installation section connected in sequence from top to bottom, an openable cabinet door 12 is provided on the front of the receiving section, and an air inlet 13 is provided on the back of the installation section, the bearing plate 3 is detachably arranged inside the receiving section, the intercepting plate 4 is detachably arranged in the air inlet 13, and the heat dissipation fan 5 is arranged inside the installation section.

[0034] Specifically, in order to facilitate the partitioning of the internal space of the cabinet 1, reasonably set the distribution of the air flow channel and provide sufficient installation space for the electrical components, a partition should be provided inside the installation section, and an air inlet cavity 14 is formed on one side of the partition close to the air inlet 13, and an equipment cavity 15 is formed on the other side, and an air outlet 25 is provided on the side wall of the equipment cavity 15. The carrier plate 3 can provide an installation base for the electrical components that need to be installed in the device. When the carrier plate 3 is installed in the accommodating section, a accommodating cavity 16 for accommodating the electrical components will be formed on one side of the carrier plate 3 close to the cabinet door 12, and a heat dissipation cavity 17 will be formed on the other side, and a guide cavity 11 for convenient gas flow should be provided inside the guide section. To facilitate the flow of gas between the cavities inside the cabinet 1, the air intake cavity 14 should be connected to the heat dissipation cavity 17 through the first connecting hole 21, the heat dissipation cavity 17 should be connected to the guide cavity 11 through the second connecting hole 22, the guide cavity 11 should be connected to the accommodating cavity 16 through the third connecting hole 23, and the accommodating cavity 16 should be connected to the equipment cavity 15 through the fourth connecting hole 24.

[0035] During assembly, the staff should place the heat dissipation fan 5 inside the equipment cavity 15, and the air inlet end of the heat dissipation fan 5 is connected to the fourth connecting hole 24, and the air outlet end is connected to the air outlet 25. When the heat dissipation fan 5 is started, the negative pressure generated by the heat dissipation fan 5 can make the air in the external environment enter the interior of the device through the air inlet 13, and flow along the order of the air inlet cavity 14, the heat dissipation cavity 17, the guide cavity 11, and the accommodating cavity 16, and finally enter the heat dissipation fan 5 in the equipment cavity 15, and then leave the device through the air outlet 25.

[0036] Compared with traditional distribution cabinets, the shape of the air flow channel in this device is less complex, and the distance between the accommodating cavity 16 and the air inlet end of the heat dissipation fan 5 is shorter, thereby ensuring a faster air flow speed inside the accommodating cavity 16, thereby improving the heat dissipation effect of electrical components.

[0037] Since foreign matter such as dust or flying catkins will inevitably be entrained in the outside air, in order to prevent foreign matter from entering the device along the air inlet 13, a plurality of filter holes 41 should be provided on the interception plate 4. In order to realize the assembly of the interception plate 4, the side wall of the installation section of this embodiment is also provided with an installation cutout 18 connected to the air inlet 13. During assembly, the staff can insert the interception plate 4 into the air inlet 13 along the installation cutout 18 so that the interception plate 4 blocks the air inlet 13. When the outside air contacts the interception plate 4, foreign matter with a particle size larger than the aperture of the filter hole 41 will be intercepted outside the interception plate 4, thereby reducing the probability of foreign matter blockage inside the device.

[0038] Optionally, in order to prevent clothes in the outside air from entering the device along the joint gap between the interception plate 4 and the air inlet 13, a receiving groove 131 for receiving the edge of the interception plate 4 may be provided on the inner side wall of the air inlet 13. When the interception plate 4 is installed in the air inlet 13, the presence of the receiving groove 131 can increase the contact area between the inner wall of the air inlet 13 and the interception plate 4, thereby improving the sealing effect of the joint gap.

[0039] In order to facilitate the cleaning of foreign matter on the outside of the interception plate 4, a cleaning strip 7 should be provided on the side wall of the air inlet 13 near the installation cutout 18. When the worker pulls the interception plate 4 toward the outside of the installation cutout 18, the relative movement between the interception plate 4 and the cleaning strip 7 enables the cleaning strip 7 to scrape the interception plate 4, thereby causing foreign matter attached to the outside of the interception plate 4 to fall off, thereby preventing the interception plate 4 from being attached and blocked by foreign matter.

[0040] Optionally, in order to improve the scraping effect of the cleaning strip 7 on the intercepting plate 4, a cleaning scraper 71 may be further provided on the side wall of the cleaning strip 7 close to the intercepting plate 4. It should be noted that the blade of the cleaning scraper 71 should fit the outer side wall of the intercepting plate 4 so that the cleaning scraper 71 can smoothly scrape away foreign matter when the intercepting plate 4 moves.

[0041] In addition, in order to prevent the intercepting plate 4 from being separated from the air inlet 13 during use, an operating strip 42 may be provided at one end of the intercepting plate 4 away from the air inlet 13 in this embodiment. Figure 2 As shown, a locking bolt 421 is provided on the operating strip 42, and a bolt hole for accommodating the locking bolt 421 is provided on the side wall of the mounting section. When the worker completely inserts the intercepting plate 4 into the air inlet 13, the operating strip 42 will fit with the outer side wall of the mounting section, and the locking bolt 421 can be screwed into the bolt hole to fix the position of the intercepting plate 4.

[0042] During actual use, foreign matter carried in the outside air may have a variety of particle sizes. Therefore, after being filtered and intercepted by the interception plate 4, small-sized foreign matter will still enter the interior of the device. In order to enhance the interception effect of the device on foreign matter, a detachable filter sponge block 6 may be provided inside the air intake cavity 14. When the gas containing small-sized foreign matter comes into contact with the filter sponge block 6, the small-sized foreign matter will be intercepted inside the filter sponge block 6, thereby further reducing the probability of foreign matter entering the air flow channel. Accordingly, after the device has been used for a period of time, the staff can also provide sufficient operating space for the disassembly and assembly of the filter sponge block 6 by disassembling the interception plate 4, thereby facilitating the regular replacement of the filter sponge block 6.

[0043] Figure 7 This is a schematic diagram of the structure of the carrier plate 3 in this embodiment. As shown in the figure, in order to improve the heat dissipation effect of the device, a plurality of heat-conducting fins 31 may be provided on the side wall of the carrier plate 3 close to the heat dissipation cavity 17, and a heat-conducting channel is provided between any two adjacent heat-conducting fins 31.

[0044] Since the electrical components in the receiving cavity 16 are all mounted on the carrier plate 3, the heat generated by the electrical components during operation will be transferred to the inside of the carrier plate 3. The heat transfer area of ​​the carrier plate 3 in the heat dissipation cavity 17 can be increased by providing the heat conducting fins 31, thereby accelerating the heat transfer speed between the carrier plate 3 and the circulating airflow, thereby improving the heat dissipation effect of the electrical components.

[0045] It should be noted that in order to prevent the existence of the thermal fins 31 from affecting the flow speed of air in the heat dissipation cavity 17, the thickness of the thermal fins 31 should be less than one tenth of the width of the thermal channel, thereby providing sufficient space for the flow of air with the help of the thermal channel.

[0046] Optionally, in order to facilitate the staff to regularly clean and maintain the heat-conducting fins 31, a cleaning port aligned with the heat-conducting fins 31 may be provided on the back of the accommodating section, and a detachable baffle 19 may be provided on the cleaning port. When the device needs to be maintained, the staff may remove the baffle 19, thereby facilitating the staff to clean the heat-conducting fins 31 along the cleaning port.

[0047] The effects of the above scheme are described below:

[0048] This embodiment provides a power distribution cabinet that is easy to dissipate heat and clean. It can form an air flow channel through the air intake cavity, the heat dissipation cavity, the guide cavity, the accommodating cavity and the equipment cavity to achieve heat dissipation of electrical components. It can also scrape the interception plate through the cleaning strip to avoid clogging of the interception plate. Secondly, the device is provided with heat-conducting fins on the carrier plate, so that the heat dissipation effect of the electrical components can be improved. In addition, the device can also perform secondary filtration on the gas through the filter sponge block, thereby reducing the probability of foreign matter appearing in the air flow channel.

[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
