[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1 to 6This utility model provides a technical solution: a heat dissipation and noise reduction system for a charging pile, including a charging pile, a cabinet 1 and a base 6. The cabinet 1 includes a front door 5, a heat dissipation duct 3 and an exhaust door 4. The front door 5 and the exhaust door 4 are hinged to both sides of the cabinet 1. The compartment on the side of the heat dissipation duct 3 near the front door 5 is the front compartment 2. A charging gun is inserted into the side of the front compartment 2. The front compartment 2 and the exhaust door 4 are located on both sides of the heat dissipation duct 3. The heat dissipation duct 3 includes a fan installation compartment 31, a hot air rising compartment 32, a module compartment 33 and an air intake compartment 34 arranged sequentially from top to bottom. The fan installation compartment 31, the hot air rising compartment 32, the module compartment 33 and the air intake compartment 34 are connected. Adjacent compartments are separated by a partition 37, and the partition 37 connects the adjacent compartments. An air guide compartment 41 is fixed on the exhaust door 4. An air guide port 42 is opened at the upper end of the air guide compartment 41. The other end of the air guide compartment 41 An air outlet 43 is provided at the top, located on the exhaust door 4. The fan mounting chamber 31 is connected to the air guide 42. The air inlet chamber 34, module chamber 33, hot air rising chamber 32, fan mounting chamber 31, and air guide chamber 41 form a heat dissipation air duct. When the hot air rises to the top of the cabinet 1, it is discharged through the air guide chamber 41. The heat dissipation air duct is optimized so that the heat dissipation part is a straight cylinder. The cold air at the bottom directly cools the charging module 7, reducing the number of corners, resulting in low resistance and good heat dissipation. Two cooling fans are fixed in the fan mounting chamber 31. The cooling fans are located above the module chamber 33. The cooling fans draw heat out of the cabinet 1 and discharge it into the air guide chamber 41. The cooling fans are installed in the heat dissipation channel, located in the middle of the charging pile and inside the air guide chamber 41, which increases the obstruction of the cooling fans and reduces the transmission of cooling fan noise.

[0018] like Figure 5 As shown, the air intake chamber 34 is connected to the base 6, allowing the air below the base 6 to enter the heat dissipation channel. The base 6 can be placed on the cable trench, which is 1m below the ground, where the air temperature is lower than the outside temperature, resulting in good heat dissipation.

[0019] An air inlet cotton 61 is fixed on the top surface of the base 6. The air inlet cotton 61 filters the air and reduces the entry of dust.

[0020] like Figure 5 and 6 As shown, the air outlet 43 and the air guide 42 are distributed on different sides of the air guide chamber 41. The air duct inside the air guide chamber 41 is Z-shaped. The hot air is guided through the Z-shaped air duct. The air outlet 43 is opened on the side of the exhaust door 4 and is located in the middle and lower part, which reduces the probability of outdoor rainwater entering the charging pile.

[0021] Multiple charging modules 7 are installed inside the module compartment 33. Each charging module 7 is equipped with an internal fan. The charging module 7 also includes a speed control unit to adjust the speed of the internal fan. The charging module 7 controls the speed of the internal fan to reduce the speed while meeting the heat dissipation efficiency, thereby reducing the noise of the charging module.

[0022] like Figure 7 As shown, the charging pile also includes a main control board 9 and a temperature monitoring module 8. The main control board 9 is connected to the charging module 7. The main control board 9 monitors the temperature of the charging module 7 in real time through the temperature monitoring module 8. The charging module controls the start of the internal fan or the cooling fan at different temperatures to improve the heat dissipation efficiency and meet the heat dissipation requirements.

[0023] The charging module 7 includes a circuit rectifier unit and a current regulation unit. The circuit rectifier unit converts AC power into DC power, and the current regulation unit is used to regulate the output current of the charging pile and control the charging power.

[0024] The main control board 9 includes a communication unit or a speed control unit and is connected to the cooling fan. The main control board 9 adjusts the speed of the cooling fan through PWM signals or voltage, so that the cooling fan rotates at the lowest possible speed while meeting the heat dissipation efficiency, thereby reducing noise generation.

[0025] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
