Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.
[0028] Charging pile main units typically employ either an integrated or modular design, meaning that components such as AC input, power conversion, signal control, and power output are centrally located within a cabinet. This design requires sequential assembly of numerous fragmented parts and devices from the inside out, resulting in a long production cycle and requiring increased manpower and production space to improve capacity. Furthermore, all functional unit tests can only be performed after the entire unit is assembled, making batch anomalies prone to occur and leading to high rework costs. The use of direct ventilation ducts and axial flow fans for heat dissipation results in significant noise and heat loss. Moreover, as the functions of charging piles become more complex, subsequent maintenance requires disassembly at each stage, increasing maintenance difficulty and time costs.
[0029] To overcome the aforementioned deficiencies in related technologies, this embodiment provides a charging pile host.
[0030] like Figure 1-8 As shown, in this embodiment, the charging pile host includes: a cabinet 1, a power module 2 fixed inside the cabinet 1, and a fan 133; the cabinet 1 is also provided with an air inlet channel a and an air outlet channel d along its perimeter; a baffle plate 31 is also installed inside the cabinet 1, and the baffle plate 31 and the cabinet 1 enclose a first transition channel b and a second transition channel c; the air inlet channel a connects to the outside to the first transition channel b, the first transition channel b is also connected to the air inlet end of the power module 2, and the outlet of the air inlet channel a is set to the side away from the power module 2; the fan 133 is installed at the end of the power module 2 away from the air inlet channel a, the second transition channel c connects to the air outlet end of the power module 2 to the fan 133, and the air outlet channel d connects to the outside to the fan 133.
[0031] Specifically, in the charging pile host of this embodiment, such as Figure 3 As shown, the airflow path within the cabinet 1 is: outside → inlet channel a → first transition channel b → power module 2 → second transition channel c → outlet channel d → outside. In this embodiment, inlet channel a and outlet channel d are arranged along the perimeter of the cabinet 1. The first transition channel b connects inlet channel a to power module 2, and the second transition channel c connects power module 2 to outlet channel d. This bend and extension of the airflow path effectively increases fluid resistance, thereby reducing airflow velocity and thus effectively reducing the noise of the charging pile host. In this embodiment, the use of a baffle plate 31 to enclose the cabinet 1 forms a thermally isolated air duct structure, which is beneficial to improving the safety and stability of the charging pile host.
[0032] In this embodiment, the charging pile host also includes a fixing frame 3 installed in the cabinet 1 and forming multiple installation compartments 32. The windproof plate 31 and the power module 2 are both fixed to the fixing frame 3. The charging pile host also includes an AC power distribution unit 4, a power distribution unit 5, a control unit 7, and a DC output unit 6 connected to one side of the power distribution unit 5, which are respectively fixed in different installation compartments 32. The power module 2 is electrically connected to the AC power distribution unit 4 in the cabinet 1. The power module 2, the power distribution unit 5, and the DC output unit 6 are also electrically connected to the control unit 7.
[0033] Specifically, the fixing frame 3 in this embodiment can be a sheet metal frame, which is structurally stable and has strong support. In this embodiment, the structure of the charging pile host is integrated into multiple independent modular units (i.e., power module 2, AC power distribution unit 4, power allocation unit 5, control unit 7, and DC output unit 6) according to different functions. Each modular unit can be independently produced, assembled, and tested, which helps to shorten the production cycle and reduce maintenance costs. Among them, the power allocation unit 5 is made into an independent component, which can be arbitrarily matched and assembled, and pre-installed and tested outside the cabinet, which helps to improve production efficiency and testing efficiency. The DC output part is modularized, that is, an independent DC output unit 6 is set up, which facilitates testing and later maintenance. The AC power distribution unit 4 and the DC output unit 6 are isolated, which helps to reduce circuit interference and improve the safety and stability of the charging pile system.
[0034] like Figure 1-5As shown, in this embodiment, the power module 2 and the power distribution unit 5 are distributed vertically, the AC power distribution unit 4 and the control unit 7 are both located on one side of the power distribution unit 5, and the AC power distribution unit 4 and the control unit 7 are distributed front to back; the windbreak plate 31 includes a first partition, a second partition and a third partition, the first partition is fixed between the power module 2 and the power distribution unit 5, the second partition is located on the side of the AC power distribution unit 4 away from the control unit 7, and the third partition is located on the side of the control unit 7 away from the AC power distribution unit 4; the cabinet 1, the fixing frame 3, the second partition and the front edge of the first partition together form a first transition channel b, and the cabinet 1, the fixing frame 3, the rear edge of the first partition and the third partition together form a second transition channel c.
[0035] Specifically, the mounting bracket 3 can be a hollow frame composed of multiple horizontal sheet metal parts and multiple vertical sheet metal parts. Components such as the AC power distribution unit 4, power distribution unit 5, and control unit 7 can be pre-installed on the outside of the cabinet 1 and then assembled into the corresponding mounting compartment 32 in sequence using self-tapping screws and combination bolts. The power module 2 can be located on the upper left side of the cabinet 1, the power distribution unit 5 can be located on the lower left side of the cabinet 1, the DC output unit 6 can be installed on the rear side of the power distribution unit 5, the AC power distribution unit 4 can be located on the lower right front side of the cabinet 1, and the control unit 7 can be located on the lower right rear side of the cabinet 1. The fan 133 can be located on the upper rear side of the cabinet 1, and the first partition, second partition, and third partition can be fixed to the mounting bracket 3 with screws. The first partition (upper and lower hot / cold partition) separates the power module 2 and the power distribution unit 5 on the left side inside the cabinet 1. The second partition is located in front of the AC power distribution unit 4. A clearance opening connecting the left and right sides is also formed above the front side of the mounting bracket 3. Thus, the cabinet 1, the mounting bracket 3, the front side of the second partition, and the front edge of the first partition can jointly enclose and form a first transition channel b, allowing airflow to flow from right to left within the first channel. The third partition can be a partition located behind the control unit 7 (this partition is also an upper and lower hot / cold partition). Thus, the cabinet 1, the mounting bracket 3, the rear edge of the first partition, and the top side of the third partition can enclose and form a second transition channel c. The hot air after passing through the power module 2 reaches the second transition channel c and can be carried by the fan 133 into the air outlet channel d and then discharged outside the cabinet 1.
[0036] Furthermore, such as Figure 1 , 2 As shown in Figures 6 and 7, in this embodiment, the cabinet 1 includes a cabinet body 11 and a front door 12 installed on the cabinet body 11. A first air duct shell 122 is provided on the inner side of the front door 12. The front door 12 has an air inlet 121. The first air duct shell 122 and the front door 12 enclose each other to form an air intake channel a. The outlet of the air intake channel a is located on one side of the first air duct shell 122.
[0037] Specifically, an air intake channel a is formed by enclosing the front door 12 of the cabinet 1 with an air duct shell. The outlet of the air intake channel a can be located at the right edge of the first air duct shell 122, which helps to extend the air duct path, reduce wind resistance, and thus reduce the noise of the fan 133. In some more specific embodiments, two front doors 12 can be symmetrically arranged, that is, a left front door 12 and a right front door 12 are respectively hinged to the left and right sides of the cabinet 11. The left front door 12 and the right front door 12 can be enclosed with the corresponding first air duct shell 122 to form the corresponding air intake channel a. Setting up multiple air intake paths in this way helps to improve the heat dissipation efficiency of the charging pile host.
[0038] In this embodiment, a louver 123 is also installed on the inner wall of the front door 12, and the louver 123 is directly opposite the air inlet 121. The inclined design of the louver 123 allows rainwater to flow down along the blades, thereby preventing rainwater from entering the cabinet 1 and improving the waterproof performance of the charging pile host. Furthermore, in this embodiment, the outlet of the air inlet channel a is a filter structure. The filter structure can mechanically filter the airflow, thereby preventing impurities from colliding and causing noise in the air duct and cabinet 11, and also preventing impurities from entering the cabinet 11 and affecting the internal components.
[0039] like Figure 1 , 2 As shown in Figures 7 and 8, in this embodiment, the cabinet 1 also includes a rear door 13 installed on the rear side of the cabinet body 11. The rear door 13 is provided with an air outlet 131. The inner wall of the rear door 13 is also provided with a second air duct shell 132. An assembly port is opened on the second air duct shell 132. The fan 133 is fixed at the assembly port. The second air duct shell 132 and the rear door 13 enclose each other to form an air outlet channel d. The air outlet channel d connects the assembly port to the air outlet 131.
[0040] Specifically, the second air duct shell 132 simultaneously serves the purposes of fixing the fan 133 and forming the air outlet channel d. In some specific embodiments, two rear doors 13 can be symmetrically arranged, namely, a left rear door 13 and a right rear door 13 respectively hinged to the left and right sides of the cabinet 11. The left and right rear doors 13 can be respectively enclosed with the corresponding second air duct shell 132 to form corresponding air outlet channels d. By setting multiple air outlet paths in this way, the heat dissipation efficiency of the charging pile host can be further improved.
[0041] In this embodiment, sound-absorbing cotton 8 can be installed in either the air inlet channel a or the air outlet channel d. In some embodiments, the sound-absorbing cotton 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. The sound-absorbing cotton 8 can also be rock wool, which has advantages such as a high sound absorption coefficient and moisture resistance and corrosion resistance.
[0042] like Figure 1 and8 As shown, in this embodiment, multiple power modules 2 are configured; the charging pile host also includes an assembly shell 9 for fixing to the mounting bracket 3. The assembly shell 9 has a receiving cavity 91, and the receiving cavity 91 has a mounting position adapted to each power module 2. Each power module 2 is fixed in its corresponding mounting position. That is, in some specific embodiments, a separate mounting component can be set for each power module 2, so that multiple power modules 2 can be fixed together and then installed into the cabinet 1. In some more specific embodiments, each mounting position of the assembly shell 9 is also provided with a socket component 93 adapted to the power module 2, so that the power module 2 can be connected and communicated with other related units through the socket component 93. The outer side of the assembly shell 9 can be provided with a hanging ear 94 (i.e., a fixing block). The hanging ear 94 can be provided with a mounting hole, so that the hanging ear 94 can be fixed to the mounting bracket 3 by screws, thereby realizing a stable assembly between the power module 2 and the mounting bracket 3. Furthermore, in this embodiment, a guide plate 92 is also provided between adjacent mounting positions within the receiving cavity 91; the guide plate 92 can position adjacent power modules 2, improve the connection stability between the power module 2 and the socket assembly 93, and during the assembly process, the guide plate 92 can also play a guiding role, allowing the user to easily and quickly push the power module 2 into the assembly shell 9, making the assembly operation simple and convenient.
[0043] 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.
