[0027] An embodiment of the present utility model relates to a cabinet, referring to Figures 1 - 6 , the cabinet has a first side 1 and a second side 2 that are relatively spaced apart. As Figure 4As shown in the figure, the cabinet includes a partition 3, which is connected between the first side 1 and the second side 2 and divides the space inside the cabinet into a front compartment 4 and a rear compartment 5. The front compartment 4 can be used to install distribution devices 8, and the rear compartment 5 can be used to install high-power devices. The partition 3 can be made of heat-insulating material to prevent the heat generated by the high-power devices installed in the rear compartment 5 from radiating to the front compartment 4.

[0028] The first side 1 of the cabinet has a rear compartment air inlet structure 12 communicating with the rear compartment 5, and the second side 2 has an air outlet structure 21 communicating with the rear compartment 5. The rear compartment air inlet structure 12 and the air outlet structure 21 are connected through the rear compartment 5, and the devices in the rear compartment 5 are installed between the rear compartment air inlet structure 12 and the air outlet structure 21. The second side 2 can also be provided with a fan installation position 24 for installing a fan to promote the air flow between the rear compartment 5 and the outside of the cabinet, and take out the heat through the air outlet structure 21 to realize the heat dissipation in the rear compartment 5. An axial flow fan can be selected as the fan. When the fan works, the air flow enters the rear compartment 5 from the rear compartment air inlet structure 12 and then is discharged from the rear compartment 5 through the air outlet structure 21. The air outlet structure 21 can include an air outlet duct, and the second side 2 is also provided with a fan installation position 24, and the fan installation position 24 is arranged in the air outlet duct for installing the fan. Optionally, the rear compartment air inlet structure 12 includes a plurality of louver air vents, and the angle of the louvers can be reasonably set to reduce the dust entering the rear compartment 5. At least part of the rear compartment air inlet structure 12 is arranged opposite to the air outlet structure 21 to facilitate enhanced convective heat dissipation.

[0029] In an example for comparison, a setting method for the heat dissipation of the front compartment 4 is to open air holes communicating with the rear compartment 5 on the left and right sides of the front compartment 4, one side of the air holes is close to the rear compartment air inlet structure 12 and the other side of the air holes is far from the rear compartment air inlet structure 12. The cold air flowing into the rear compartment 5 from the rear compartment air inlet structure 12, a part of it flows through the rear compartment 5 towards the air outlet structure 21, and the other part flows into the front compartment 4 from the air holes close to the rear compartment air inlet structure 12. After flowing through the front compartment 4, the hot air flows out from the air holes on the other side of the front compartment 4, converges with the hot air flowing through the devices in the rear compartment 5 in the rear compartment 5, and flows out through the air outlet structure 21 to realize the heat dissipation of the front compartment 4. However, in this way, since the air flows for the heat dissipation of both the front compartment 4 and the rear compartment 5 rely on the power of the fan in the rear compartment 5, the power requirement for the fan is relatively high; and during the operation of the equipment, the dust entering and leaving the cabinet through the rear compartment air inlet structure 12, the air outlet structure 21, etc. accumulates at the air holes, and the hot air in the rear compartment 5 is also likely to flow back into the front compartment 4, affecting the heat dissipation of the front compartment 4.

[0030] In the embodiment of the present invention, referring to Figures 3 - 5, a through ventilation hole 31 is formed in the partition plate 3 to communicate the front compartment 4 and the rear compartment 5. The first side 1 of the cabinet has a front compartment air inlet structure 11 communicating with the front compartment 4, and the position of the ventilation hole 31 on the partition plate 3 is higher than the position of the front compartment air inlet structure 11. The front compartment air inlet structure 11 may include a front compartment air inlet hole provided on the outer surface of the first side 1 of the cabinet and a front compartment air inlet duct communicating the front compartment air inlet hole with the front compartment 4. Since the density of hot air is small, the hot air in the front compartment 4 can rise and be discharged into the rear compartment 5 through the ventilation hole 31, while the cold air outside the cabinet can enter the front compartment 4 through the front compartment air inlet structure 11 with a lower position. Preferably, the ventilation hole 31 is arranged close to the top of the cabinet (as shown in Figure 3 and Figure 5 ), and the front compartment air inlet structure 11 is arranged close to the bottom of the cabinet (as shown in Figure 1 and Figure 4 ), so as to increase the height difference between the front compartment air inlet structure 11 and the ventilation hole 31, which is more conducive to promoting air convection and promoting the heat dissipation of the front compartment 4 under the chimney effect. Moreover, due to the temperature difference between the inside of the front compartment 4 and the outside of the cabinet, the air pressure inside the front compartment 4 is lower than the air pressure outside the cabinet, which promotes the colder air outside the cabinet to enter the front compartment 4 through the front compartment air inlet structure 11. And, since the high-power devices with large heat generation are arranged in the rear compartment 5, the heat generation of the devices in the rear compartment 5 is greater than that of the devices in the front compartment 4, resulting in the temperature in the rear compartment 5 being higher than that in the front compartment 4. The temperature difference between the front compartment 4 and the rear compartment 5 makes the air pressure in the rear compartment 5 lower than that in the front compartment 4, which promotes the air in the front compartment 4 to flow into the rear compartment 5 through the ventilation hole 31. Thus, the air outside the cabinet enters the front compartment 4 through the front compartment air inlet structure 11, then enters the rear compartment 5 through the ventilation hole 31, and finally is discharged from the cabinet through the air outlet structure 21 provided on the second side 2 of the cabinet and communicating with the rear compartment 5.

[0031] Compared with the above comparative example, the technical solution of the embodiment of the present invention makes the air flow for cooling the front compartment 4 directly enter from outside the cabinet without passing through the rear compartment 5 first by arranging the front compartment air inlet structure 11 on the first side 1 of the cabinet, reducing the risk of blockage on the air inlet side of the front compartment 4. Further, a dust-proof net can be arranged on the front compartment air inlet structure 11 to reduce the risk of blockage of the front compartment air inlet structure 11. Moreover, the embodiment of the present invention realizes the ventilation and heat dissipation of the front compartment 4 by reasonably arranging the positions of the front compartment air inlet structure 11 and the ventilation hole 31, which is beneficial to reducing energy consumption.

[0032] Furthermore, in this embodiment, the ventilation holes 31 are close to the air outlet structure 21. Since there is an air flow from the rear compartment air inlet structure 12 to the air outlet structure 21 in the rear compartment 5, and the air in the rear compartment 5 is discharged from the air outlet structure 21 under the drive of the fan, a low-pressure area is formed in the area of the rear compartment 5 close to the air outlet structure 21. When the ventilation holes 31 are arranged at a position close to the air outlet structure 21, it further promotes the air in the front compartment 4 to be discharged into the rear compartment 5 through the ventilation holes 31, thus promoting the heat dissipation of the front compartment 4.

[0033] In some embodiments, such as Figure 1 , Figure 4 and Figure 6 shown, the first side 1 of the cabinet is provided with a first side door 14, the position of the first side door 14 corresponds to the rear compartment 5, and the first side door 14 is hinged to the cabinet in an openable and closable manner, so as to facilitate the installation of corresponding equipment or devices into the rear compartment 5. The rear compartment air inlet structure 12 can be arranged on the first side door 14, and the rear compartment air inlet structure 12 can occupy a relatively large area on the first side door 14, so as to facilitate air convection heat dissipation. The first side 1 of the cabinet is provided with a first side plate 13 corresponding to the front compartment 4, and the front compartment air inlet structure 11 is arranged on the first side plate 13, which is beneficial to achieving a good separation between the front compartment 4 and the rear compartment 5.

[0034] In some embodiments, such as Figure 2 , Figure 3 and Figure 5 shown, the second side 2 of the cabinet is provided with a second side door 23, the position of the second side door 23 corresponds to the rear compartment 5, and the second side door 23 is hinged to the cabinet in an openable and closable manner, so as to facilitate the installation of corresponding equipment or devices into the rear compartment 5. The air outlet structure 21 can be arranged on the second side door 23, and the fan installation position 24 can be arranged on the second side door 23. The second side 2 of the cabinet is provided with a second side plate 22 corresponding to the front compartment 4, and the second side plate 22 is spaced from the air outlet structure 21, which is beneficial to achieving a good separation between the front compartment 4 and the rear compartment 5.

[0035] Optionally, referring to Figure 1 and Figure 6 , the cabinet further has a front door 6, the front door 6 is arranged opposite to the partition 3 at an interval and is arranged on the cabinet in an openable and closable manner, which is convenient for disassembling and assembling devices into the front compartment 4.

[0036] Another aspect of the present utility model also relates to a charging pile, which is used for charging an electric vehicle. Such as Figure 5 and Figure 6As shown in the figure, the charging pile uses the cabinet in at least some of the above embodiments. The charging pile further includes a power module 7 and a power distribution device 8. The power module 7 is used to convert alternating current into direct current to provide a stable charging power source for the battery of the electric vehicle. The power module 7 is arranged in the rear compartment 5, and the power distribution device 8 is arranged in the front compartment 4 and is electrically connected to the power module 7. By using the cabinet in at least some of the above embodiments, effective heat dissipation of the charging pile can be achieved.

[0037] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various modifications and changes can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
