[0036] Specifically, a front protective bezel 35 is provided on the front side of the front door frame 31 and is secured to the front door frame 31 via screws. A rearward-projecting recessed platform 332 is provided in the middle of the mounting plate 33. Mounting holes 331 are provided in the recessed platform 332, and the mounting bracket 34 is secured to the rear side of the recessed platform 332. The edges of the mounting plate 33 are secured to the front door frame 31 via screws.

[0037] Specifically, two vertical grooves 13 are fixedly connected to the left side of the upper inner portion of the box body. The cross-sections of the two upright posts 11 on the left are both U-shaped, and the two upright posts 11 on the left are respectively fixedly connected to the two vertical grooves 13 on the left.

[0038] Specifically, two vertical grooves 13 are fixedly connected to the right side of the upper inner cavity of the box body. The cross sections of the two upright posts 11 on the right side are both rectangular waves. The two upright posts 11 on the right side are respectively fixed to the two vertical grooves 13 on the right side.

[0039] Specifically, the transverse edges of both sides of the rear wall of the inverter 2 extend outward to form outer flanges 23 , and the outer flanges 23 are connected to the columns 11 on the corresponding sides by hand screws 5 .

[0040] Specifically, the rear wall of the inverter 2 is provided with two air exhaust holes, and an air intake fan 21 is fixedly connected to the inner side of each air exhaust hole.

[0041] Specifically, a partition plate 14 is fixed to the middle of the inner cavity of the box along the vertical direction, and a vertical plate 15 is fixed to the upper side of the partition plate 14. The partition plate 14, the vertical plate 15 and the inner wall of the box form an upper cavity, and the cavity below the partition plate 14 is the lower cavity.

[0042] The working principle of this utility model high-efficiency heat dissipation charging pile is as follows:

[0043] See Figure 6 The partition plate 14, the vertical plate 15 and the inner wall of the box form an upper cavity, and the cavity below the partition plate 14 is the lower cavity. There is an airflow space between the front wall of the inverter 2 and the mounting frame 34 ( Figure 6 A in the middle), a vent hole 141 is provided on the front side of the partition plate 14, and the vent hole 141 connects the upper cavity with the lower cavity. The longitudinal length of the vent hole 141 is the same as the air flow space ( Figure 6 The longitudinal distance corresponds to point A in the middle.

[0044] When the charging pile is working, multiple inverters 2 will generate heat, so it is necessary to dissipate heat from the inverter 2 in a timely manner to ensure the working performance of the charging pile. To this end, an air inlet fan 21 is provided on the rear side of the inverter 2 housing, and an air outlet grille 22 is provided on the front side of the inverter 2 housing. The air inlet fan 21 draws air from the rear side of the upper cavity of the box into the inverter 2 housing, and then discharges it through the air outlet grille 22 to remove the heat inside the inverter 2. The hot air discharged through the air outlet grille 22 reaches the air flow space ( Figure 6 A in the middle), that is, it is drawn out of the box by the exhaust fan (not shown) provided in the mounting frame 34, and the airflow formed by the exhaust of the exhaust fan (not shown) blows the flip blade 32, so that the flip blade 32 (such as Figure 8 When the exhaust fan (not shown) does not rotate, the blade strips 32 are tilted downwards and are in a drooping state to block rainwater.

[0045] Airflow space ( Figure 6 There is sufficient space (at point A) to collect the hot air discharged through the air outlet grille 22 and flowing into the upper chamber through the vents 141. The inner cavity of the sink 332 also has sufficient space for the hot air to flow, allowing the exhaust fan (not shown) installed in the mounting frame 34 to smoothly draw and exhaust air, thereby achieving rapid air flow in the upper chamber and rapid heat dissipation.

[0046] Low-temperature fresh air enters the rear side of the upper chamber through the gaps between the fixed blades 42 and is drawn into the housing of the inverter 2 by the air intake fan 21. The stabilizing frame 43 is provided with a plurality of vertical bars 431, which abut against the inner edges of the fixed blades 42, thereby stabilizing the fixed blades 42 and increasing their bending strength.

[0047] The four vertical slots 13 and the four uprights 11 are all of sheet-shaped bent structures, which have fast heat dissipation and do not store heat, thereby helping to avoid heat accumulation in the cavity.

[0048] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments using the technical contents disclosed above without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
