Technical Field
[0001] This utility model belongs to the field of new energy technology, and in particular relates to a charging pile host. Background Technology
[0002] With the increasing popularity of electric vehicles, charging stations, as an important supporting facility, are being used more and more frequently. However, existing charging stations often generate significant noise during operation, especially at night or in residential areas, where the noise problem is particularly prominent, affecting the lives and user experience of surrounding users. Related technologies typically aim to reduce charging station noise by using low-noise fans or optimizing fan blade shapes; however, these measures only reduce noise to a certain extent, with limited noise reduction effects, and are insufficient to meet user needs.

[0005] Furthermore, the air duct component includes a main body and a guide section bent and connected to the outer periphery of the main body. The side of the guide section away from the main body is connected to the inner wall of the cabinet, and the air duct opening is located on the guide section.
[0006] Furthermore, the angle between the airflow guide and the cabinet wall is 30° to 60°.
[0007] Furthermore, in the vertical direction, the assembly port and the air outlet are staggered.
[0008] Furthermore, sound-absorbing components are installed inside the second air duct.
[0009] Furthermore, the sound-absorbing components are made of glass wool or rock wool.
[0010] Furthermore, filter cotton is installed inside the first air duct.
[0011] Furthermore, the cabinet includes a cabinet body and a front door and a rear door respectively installed on opposite sides of the cabinet body; an air inlet and an air outlet, one located on the front door and the other on the rear door; the power management module includes a charging module and a switch module electrically connected to the charging module, and a mounting bracket is provided inside the cabinet, with the charging module and the switch module respectively fixed on opposite sides of the mounting bracket.
[0012] Furthermore, the number of air duct components is two; one air duct component has an air duct opening corresponding to a charging module, and the other air duct component has an air duct opening corresponding to a switch module; and / or, the number of fans and assembly ports is two, one fan corresponds to a charging module, and the other fan corresponds to a switch module.
[0013] Furthermore, the air duct opening has a mesh structure, and / or the air inlet has a mesh structure, and / or the air outlet has a mesh structure.

This arrangement of the first and second air ducts extends the airflow path within the cabinet, effectively increasing fluid resistance and reducing airflow velocity. This helps reduce turbulence and eddies, allowing noise to be reduced within the air ducts, significantly improving the noise reduction performance of the charging pile host.

[0025] Example:
[0026] like Figure 1-6As shown, in this embodiment, the charging pile host includes: a cabinet 1, a power management module 3, an air duct component 4, a fan 6, and a mounting shell 5 with an assembly port; the power management module 3 is installed inside the cabinet 1, and air inlets 121 and air outlets 131 are respectively provided on opposite sides of the cabinet 1; the air duct component 4 is fixed to the side of the air inlet 121 inside the cabinet 1, and the inner wall of the cabinet 1 and the air duct component 4 enclose each other to form a first air duct; the side of the air duct component 4 is provided with an air duct opening 421 connecting the first air duct to the power management module 3; the mounting shell 5 is fixed to the side of the air outlet 131 inside the cabinet 1, the fan 6 is installed on the assembly port, and the mounting shell 5 and the inner wall of the cabinet 1 enclose each other to form a second air duct connecting the assembly port to the air outlet 131.
[0027] Specifically, the air duct component 4 and the cabinet 1 enclose each other to form a first air duct, allowing the airflow entering from the air inlet 121 to first pass through the first air duct and then be blown into the cabinet 1 along the side air duct opening 421, thereby carrying away the heat from the power management module 3. In this embodiment, a mounting shell 5 is also provided to enclose the cabinet 1 to form a second air duct, allowing the hot air after passing through the power management module 3 to be blown into the second air duct by the fan 6 fixed at the mounting opening, and then dissipated outside the cabinet 1 along the air outlet 131. By setting up the first and second air ducts to extend the airflow path within the cabinet 1, the fluid resistance can be effectively increased, thereby reducing the airflow velocity, which helps to reduce turbulence and eddies, thus reducing noise in the air ducts and greatly improving the noise reduction performance of the charging pile host.
[0028] In this embodiment, as Figure 3 and 4 As shown, the cabinet 1 includes a cabinet body 11 and a front door 12 and a rear door 13 respectively installed on opposite sides of the cabinet body 11; an air inlet 121 and an air outlet 131, one of which is located on the front door 12 and the other on the rear door 13; the power management module 3 includes a charging module 31 and a switch module 32 electrically connected to the charging module 31; a mounting bracket 7 is provided inside the cabinet body 11, and the charging module 31 and the switch module 32 are respectively fixed on opposite sides of the mounting bracket 7.
[0029] Specifically, such as Figure 3 and 4As shown, the cabinet 1 in this embodiment is provided with a front door 12 and a rear door 13, which can be hinged to the cabinet body 11 respectively. An air inlet 121 and an air outlet 131 are respectively located on the front door 12 and the rear door 13. Correspondingly, the air duct component 4 and the mounting shell 5 are respectively installed on the inner wall of the front door 12 and the rear door 13. The mounting bracket 7 in this embodiment can be a sheet metal fixing frame fixed inside the cabinet body 11. The charging module 31 and the switch module 32 are respectively fixed inside the cabinet body 11 by the mounting bracket 7, which helps to improve the assembly stability of the charging module 31 and the switch module 32. Since the front door 12 and the rear door 13 in this embodiment can be opened or closed respectively, during the assembly process, components such as the power management module 3, the air duct component 4, the fan 6, and the mounting shell 5 can be easily installed by opening the doors, making the assembly operation simple.
[0030] In this embodiment, there are two air duct components 4; the air duct opening 421 of one air duct component 4 is set to the charging module 31, and the air duct opening 421 of the other air duct component 4 is set to the switch module 32; and / or, there are two fans 6 and two assembly ports, with one fan 6 set to the charging module 31 and the other fan 6 set to the switch module 32.
[0031] Specifically, the front door 12 includes a left front door and a right front door. Both the left and right front doors are equipped with air inlets 121, and air duct components 4 are fixed to the inner walls of the left and right front doors respectively. The left and right front doors, together with their corresponding air duct components 4, form two independent first air ducts. The rear door 13 includes a left rear door and a right rear door. Both the left and right rear doors are equipped with air outlets 131, and the left and right rear doors, together with their corresponding mounting shells 5, form two independent second air ducts. The charging module 31 is located on the left side inside the cabinet 11, and the switch module 32 is located on the right side inside the cabinet 11. During use, two heat dissipation paths can be formed inside the cabinet 11. The first heat dissipation path is as follows: airflow enters the corresponding first air duct from the air inlet 121 of the left front door, then enters the charging module 31 along the air duct opening 421. After passing through the charging module 31, the airflow is drawn into the second air duct corresponding to the left rear door by the fan 6, and then discharged from the air outlet 131 of the left air duct. The second heat dissipation path: Airflow enters the corresponding first air duct from the air inlet 121 of the right front door, then enters the switch module 32 along the air duct opening 421. After passing through the switch module 32, the airflow is drawn into the second air duct corresponding to the right rear door by the fan 6, and then discharged from the air outlet 131 of the right air duct. This arrangement of multiple heat dissipation paths not only significantly improves the heat dissipation efficiency of the charging pile host, but also significantly improves the noise reduction effect. Figure 4As shown, in some more specific embodiments, a flow guiding structure 111 (or air duct structure) can be provided on the rear side of the cabinet 11 corresponding to the charging module 31 and the switch module 32, respectively, so that the hot airflow passing through the charging module 31 and the switch module 32 can smoothly reach the corresponding assembly port and the second air duct under the guidance of the corresponding flow guiding structure 111. It is understood that in some other embodiments, the front door 12, rear door 13, air duct component 4, fan 6, mounting shell 5, etc., can also be provided in only one form, and there is no limitation here.
[0032] In this embodiment, as Figure 3 and 5 As shown, the air duct component 4 includes a main body 41 and a guide portion 42 bent and connected to the outer periphery of the main body 41. The side of the guide portion 42 away from the main body 41 is connected to the inner wall of the cabinet 1, and the air duct opening 421 is provided on the guide portion 42. Specifically, the guide portion 42 is also the bevel on the air duct component, and the side of the guide portion 42 away from the main body 41 is fixedly connected to the inner wall of the front door 12. The guide portion 42 can guide the airflow, that is, it can buffer the turning airflow, reduce the collision between the airflow and the inner wall of the air duct, and thus reduce noise. Further, in this embodiment, the angle formed by the guide portion 42 and the wall of the cabinet 1 is 30° to 60°. Preferably, the angle formed by the guide portion 42 and the front door 12 can be 30°, 40°, 45°, 50°, 55°, 60°, etc., and is not limited here.
[0033] In this embodiment, as Figure 2 , 4 As shown in Figure 6, the assembly port and air outlet 131 are staggered in the vertical direction. This staggered arrangement extends the airflow path in the duct, further improving the noise reduction effect of the charging pile host. In one specific embodiment, the assembly port and fan 6 can be located at the upper end of the rear door 13, and the air outlet 131 at the lower end of the rear door 13. This allows the hot airflow from the cabinet 11 to enter the second duct through the upper assembly port, flow downwards, and then exit through the lower air outlet 131. It is understood that during implementation, the positions of the fan 6 and assembly port can be determined based on actual needs and with reference to the positions of the charging module 31 and the switch module 32, and are not limited here. Similarly, the position of the air outlet 131 can be specifically determined based on the shape of the rear door 13 and the position of the assembly port, and is not limited here.
[0034] In this embodiment, as in this embodiment, Figure 6As shown, a sound-absorbing component 8 is installed in the second air duct. This component 8 further absorbs noise generated within the cabinet 1, thereby enhancing the noise reduction capability of the charging pile. In some embodiments, the sound-absorbing component 8 can be glass wool, which not only has a high sound absorption coefficient but also excellent properties such as high temperature resistance and light weight. Alternatively, the sound-absorbing component 8 can be rock wool, which has advantages such as a high sound absorption coefficient and resistance to moisture and corrosion.
[0035] In this embodiment, a filter cotton is provided inside the first air duct. Specifically, the filter cotton can be tightly attached to the inside of the air duct opening 421; the filter cotton can mechanically filter the airflow, thereby preventing impurities from passing through and colliding in the air duct and cabinet 11 and generating noise, and also preventing impurities from entering the cabinet 11 and affecting the internal components.
[0036] In this embodiment, the air duct opening 421 has a mesh structure, and / or the air inlet 121 has a mesh structure, and / or the air outlet 131 has a mesh structure. By configuring the air duct opening 421, air inlet 121, and air outlet 131 as mesh structures, sufficient airflow can be ensured for heat dissipation within the cabinet 1, while also increasing airflow resistance to a certain extent, slowing down airflow speed, and thus reducing noise.
[0037] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
