[0002] Charging piles are important infrastructure for promoting the development of electric vehicles and can provide a safe and convenient charging experience for electric vehicles.

[0003] At present, existing charging piles, such as those disclosed in the invention patent with the publication number CN118457307A and the name of a charging pile, include a housing, a first power module, a third power module, and electrical components. The housing is provided with an accommodation cavity; both the first power module and the third power module are assembled in the accommodation cavity; among them, there is an accommodation space between the first power module and the third power module, and the electrical components are assembled in the accommodation space.

[0004] When this kind of charging pile is actually used, especially when installed outdoors, whenever the weather is hot, the charging pile cannot cool down in time or discharge the internal heat, which affects the service life of the internal electronic components, and there will be certain safety hazards when the charging pile continuously maintains a high temperature during use. Content of the Utility Model

[0005] In view of the deficiencies in the prior art, the utility model provides a charging pile with circulating cooling to solve the technical problem that the existing charging piles cannot cool down in time or discharge the internal heat.

[0006] The above technical object of the utility model is achieved through the following technical solutions:

[0007] A charging pile with circulating cooling includes a support frame. A module chamber for placing a power module is provided inside the support frame. Two first side doors hinged to opposite sides of the support frame and communicating with the module chamber are provided. Heat dissipation components for dissipating heat from the power module are provided on the two first side doors. Two second side doors hinged to the other two opposite sides of the support frame are provided, and cooling channels for reducing the temperature of the internal electronic components of the charging pile are provided between the two second side doors and the module chamber.

[0008] Working Principle:

[0009] This device is a charging pile with circulating cooling, mainly used for dissipating heat from the charging pile when the temperature outside or inside the charging pile is too high.

[0010] During use, when the power module in the module chamber is in use, the heat dissipation components on the two first side doors will be opened, and the external air will be inhaled between the power modules in the module chamber through the heat dissipation components, and the heat generated by the multiple power modules will be taken away.

[0011] When the temperature inside the charging pile reaches a certain level, the temperature inside the charging pile is reduced through the cooling channels arranged between the two second side doors and the module chamber.

[0012] Beneficial effects obtained:

[0013] First, a heat dissipation component is provided, which can effectively reduce the heat generated by the power module during operation, thereby reducing the temperature inside the charging pile.

[0014] Second, cooling channels are arranged on both sides of the module chamber, which can effectively reduce the temperature inside the charging pile through the set cooling channels, protecting the electronic components inside the charging pile from being damaged by high temperature.

[0021] Embodiment:

[0022] Refer to Figures 1 to 4, this device is a charging pile with circulating cooling, including a support frame. A module chamber 2 for placing the power module 1 is provided inside the support frame. Two first side doors 3 communicating with the module chamber 2 are hinged on two opposite sides of the support frame. Two second side doors 4 are hinged on the other two opposite sides of the support frame. The support frame includes a base 6, four support columns 7, and a top plate 8. The four support columns 7 are fixedly arranged on the base 6, and the other ends of the four support columns 7 extend vertically upward. The top plate 8 is fixedly arranged on the tops of the four support columns 7. The two first side doors 3 and the two second side doors 4 are respectively hinged and installed between every two support columns 7. The module chamber 2 is arranged between the base 6 and the top plate 8. A touch panel 19 is provided on one of the second side doors 4. The four-door opening and closing structure facilitates subsequent personnel to repair the inside of the charging pile. The four support columns 7 are hollow. A number of first ventilation holes 17 corresponding to the four support columns 7 are provided on the base 6, and a number of second ventilation holes 18 corresponding to the four support columns 7 are provided on the top plate 8. With such an arrangement, air enters through a number of first ventilation holes 17 and is discharged through the second ventilation holes 18 on the top plate 8 after passing through the connected support columns 7, forming an air flow circulation channel from bottom to top.

[0023] As Figure 1 and Figure 2 shown, heat dissipation components for dissipating heat from the power module 1 are provided on the two first side doors 3. The heat dissipation components include a protection net 9 and a number of exhaust fans 10. An installation hole 11 communicating with the module chamber 2 is opened on one of the first side doors 3, and the protection net 9 is arranged in the installation hole 11. An air suction hole 12 communicating with the module chamber 2 is opened on the other first side door. A number of the exhaust fans 10 are evenly arranged in the air suction hole 12. With such an arrangement, by turning on a number of exhaust fans 10, external air enters the charging pile at the air suction hole 12 and the protection net 9, and the heat generated when the power module 1 works is discharged together from the exhaust fans 10. This type of exhaust fan 10 is a combination of a motor and a fan blade, which is an existing common technology.

[0024] As Figure 2 and Figure 3As shown, a cooling channel 5 for reducing the temperature of internal electronic components of the charging pile is provided between each of the two second side doors 4 and the module chamber 2. A hollow fixing plate 13 is provided between the base 6 and the module chamber 2. Cooling holes 14 are formed on both sides of the fixing plate 13. The two cooling holes 14 are respectively communicated with the two cooling channels 5. An industrial air conditioner 15 is provided in one of the cooling channels 5. The industrial air conditioner 15 is fixedly arranged on the corresponding second side door 4. The air inlet hole of the industrial air conditioner 15 is communicated with the outside of the charging pile. The air outlet hole of the industrial air conditioner 15 is located in the cooling channel 5. A drain pipe 16 is communicated with the bottom of the industrial air conditioner 15. The drain pipe 16 vertically penetrates through the base 6 and extends outwards. With this arrangement, the temperature inside the charging pile is reduced by the industrial air conditioner 15. This type of industrial air conditioner 15 has a common structure, and its structure will not be described in detail herein.

[0025] Working principle:

[0026] During use, when the power module 1 in the module chamber 2 is in use, multiple exhaust fans 10 on the first side door 3 will be turned on, enabling external air to enter the charging pile through the air suction holes 12 and the protective net 9, and discharging the heat generated during the operation of the power module 1 from the exhaust fans 10. When the temperature inside the charging pile reaches a certain level, the industrial air conditioner 15 on the second side door 4 is turned on to provide cold air in the cooling channel 5. The cold air passes through the cooling holes 14 and the fixing plate 13 and enters the other cooling channel 5, making the overall temperature inside the charging pile balanced and achieving the effect of protecting the internal electronic components.
