[0033] Furthermore, the described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. Numerous specific details are provided in the following description to give a full understanding of embodiments of the present invention.

[0034] In response to the problems of heat dissipation, noise, and gun wire management in related technologies, this utility model provides a spiral air duct dual-gun DC charger with a simpler structure and more convenient operation.

[0035] like Figures 1 to 6 As shown, Figure 1A spiral duct dual-gun DC charger provided for an embodiment of the present utility model includes: a cabinet 100, and a front door 110, a rear frame 120, a left door 130 and a right door 140 movably disposed on the cabinet 100;

[0036] The cabinet 100 has a horizontally arranged air duct partition 160 inside, a charging module compartment 200 is arranged below the air duct partition 160, and an air outlet compartment 300 is arranged above the air duct partition 160.

[0037] The rear frame 120 is provided with an air inlet 121 below the air duct partition 160, and the left door 130 is provided with an air outlet 131 above the air duct partition 160. The area between the charging module compartment 200 and the rear frame 120 is divided into an air inlet compartment 500, the area between the charging module compartment 200 and the left door 130 is divided into a cold air compartment 600, the area between the air outlet compartment 300 and the left door 130 is divided into an air outlet compartment 800, and the area between the charging module compartment 200 and the right door 140 is divided into a hot air compartment 700.

[0038] A fan 310 is installed at the top of the air outlet duct 300 near the right door 140. An air guide baffle 320 is installed inside the air outlet duct 300. The air guide baffle 320 bends downward from above the fan 310 and extends to the side of the air outlet duct 300 near the left door 130. The fan 310 draws the airflow from the hot air chamber 700 into the air outlet duct 300, guides it through the air guide baffle 320 to the air outlet chamber 800, and then discharges it from the air outlet 131.

[0039] In this embodiment, cold air enters the air intake chamber 500 through the air inlet 121 below the rear frame 120 of the cabinet 100, then turns 90° and enters the charging module through the left-hand cold air chamber 600. The fan 310 draws the cold air into the charging module and blows out the generated hot air, which enters the right-hand hot air chamber 700. The entire right side of the cabinet 100 is the hot air chamber 700. The hot air is vertically drawn away by the fan 310 at the inlet of the exhaust duct chamber 300, creating a negative pressure in the power distribution chamber 400 and the charging module chamber 200, causing all the heat to enter the exhaust duct chamber 300. A bent baffle 320 is installed at the upper part of the exhaust duct chamber 300, ensuring that all the hot air is exhausted through the air outlet 131. The baffle 320 ensures smooth exhaust of hot air, preventing heat accumulation. The overall structure is compact, the airflow layout is optimized, and the heat dissipation efficiency is improved. The cabinet 100 has an internal air duct that passes sequentially through the air inlet 121, air inlet chamber 500, cold air chamber 600, charging module chamber 200, hot air chamber 700, air outlet duct chamber 300, air outlet chamber 800 to air outlet 131.

[0040] In some embodiments, the cabinet 100 is internally divided into a front compartment, a lower middle compartment, a middle upper compartment, a lower rear compartment, and a higher rear compartment. The front compartment is a power distribution compartment 400, the lower middle compartment is a charging module compartment 200, the lower rear compartment is an air inlet compartment 500, and the upper middle and upper rear compartments are air outlet compartments 300. The area between the charging module compartment 200 and the front door 110 is divided into a power distribution compartment 400, which is further divided from top to bottom into a DC power distribution area, a main control area, and an AC power distribution area. The charging module compartment 200 contains a frame assembly for installing charging modules, and there are gaps between the charging modules on the frame assembly. In some embodiments, the fan 310 is an axial flow fan 310, and the bending angle of the air guide baffle 320 is 30°.

[0041] In the embodiment provided by this utility model, the heat is completely discharged from the cabinet 100 through the sealed connection between the air outlet 131 inside the cabinet and the air inlet 121 of the left door 130 plate. The heat is then rapidly diffused through the diffuser-type air outlet 131 of the upper and lower structure of the left door 130 plate, which greatly improves the speed at which the hot air flows out of the cabinet 100, significantly reduces the heat of the components, and makes the overall temperature inside the cabinet ideal. The noise generated by the charging module is only partially transmitted back out at the air inlet, so the inlet noise is very low. The sound generated by the negative pressure entering the hot air exhaust chamber and the fan 310 is combined, and some of it is consumed by the air and the walls of the hot air exhaust chamber. Therefore, a large part of the noise flowing out at the hot air outlet 230 of the cabinet 100 has been eliminated, which greatly reduces the noise.

[0042] In the embodiments provided by this utility model, the spiral air duct design and optimized air duct layout achieve a reasonable distribution of airflow, forming an efficient circulating airflow, which effectively improves heat dissipation efficiency and reduces noise.

[0043] refer to Figure 7 , Figure 7 The diagram shows the air inlet chamber 500 and the cold air chamber 600. In some embodiments, the cabinet 100 also includes a base plate 150, and the air inlet chamber 500 is provided with a duct sealing rear cover plate 510 perpendicular to the base plate 150. The duct sealing rear cover plate 510 is provided with an air inlet protective louver 520.

[0044] The air intake protective louvers 520 effectively block dust and debris from entering, ensuring airflow quality. The design of the sealed air duct cover 510 enhances airflow guidance and improves cooling efficiency. Through optimized internal structure, the cabinet 100 achieves efficient heat dissipation while further reducing noise and improving overall operational stability.

[0045] In some embodiments, a cold air dustproof partition 610 is vertically arranged between the air inlet chamber 500 and the cold air chamber 600; a cold air inlet 620 is provided on one side of the charging module chamber 200 located in the cold air chamber 600.

[0046] The cold air dustproof partition 610 uses a filter screen to effectively block dust from entering the cold air chamber 600, ensuring the cleanliness of the charging module's interior. Air guide holes on the cold air dustproof partition 610 ensure smooth passage of cold air while effectively preventing dust from entering the cold air chamber 600, allowing air to enter the charging module compartment 200 through the cold air inlet 620.

[0047] In some embodiments, the area between the charging module compartment 200 and the front door 110 is divided into a power distribution function compartment 400, and an air duct baffle 210 is provided between the charging module compartment 200 and the power distribution function compartment 400.

[0048] The air duct baffle 210 effectively separates hot and cold airflows, ensuring uniform temperature within the charging module compartment 200 and improving heat dissipation efficiency. The cold air dust inlet design ensures airflow while preventing dust intrusion, extending the equipment's lifespan. The overall structure is compact, with each functional compartment working collaboratively to achieve efficient heat dissipation and noise reduction, optimizing the user experience.

[0049] refer to Figure 8 , Figure 8 The diagram shows the hot air chamber 700. In some embodiments, the charging module chamber 200 is provided with a fixing plate 220 on one side of the hot air chamber 700, and the fixing plate 220 has a hot air outlet 230. A duct sealing cover 240 is provided between the charging module chamber 200 and the hot air chamber 700.

[0050] The charging module compartment 200 and the hot air compartment 700 are separated by the air duct sealing cover 240, ensuring that hot air does not flow back into the charging module compartment 200, further improving heat dissipation efficiency. The design of the hot air outlet 230 effectively reduces heat accumulation, ensures stable operation of the charging module, and extends the service life of the equipment.

[0051] refer to Figure 9 , Figure 9 This is a schematic diagram of the sealing between the air duct outlet and the door panel; in some embodiments, the air outlet chamber 800 is vertically provided with a protective plate 810, the protective plate 810 is provided with an air outlet protective louver 820, the air outlet protective louver 820 is higher than the air duct partition 160, and the edge of the air outlet protective louver 820 is provided with a sealing strip 830.

[0052] The combined effect of the air outlet louvers 820 and sealing strips 830 on the protective plate 810 effectively prevents the intrusion of dust and foreign objects, ensuring the cleanliness and ventilation efficiency of the air outlet 131. Simultaneously, the diffuser design of the air outlet 131 makes the hot air distribution more uniform, further improving the heat dissipation effect. The gap between the duct partition 160 and the protective plate 810 is sealed with a sealing strip to ensure that the airflow within the duct is not disturbed by external factors. Through the diffuser-type air outlet 131 of the left door 130, hot air is evenly distributed, avoiding localized overheating.

[0053] In some embodiments, a touch LCD screen and a card reader are installed on the front door 110. This is used to address the human-machine interaction functions of the charger.

[0054] In some embodiments, an emergency stop button is installed on the outside of the right door 140.

[0055] In some embodiments, a charging gun holder is installed on both the outer side of the left door 130 and the outer side of the left door 130. The charging gun holder is used for placing the charging gun in its designated position.

[0056] In some embodiments, the charger has cable storage compartments installed on both sides of its upper end.

[0057] Existing chargers often have their charging cables dragging on the ground during use, necessitating a more aesthetically pleasing and efficient solution for on-site operation. This embodiment addresses this issue by installing charging cable storage compartments on both sides of the top of the charger, thus achieving effective cable management.

[0058] The preferred embodiments of the present invention have been described above with reference to the accompanying drawings, but this does not limit the scope of the present invention. Any modifications, equivalent substitutions, and improvements made by those skilled in the art without departing from the scope and spirit of the present invention should be within the scope of the present invention.
