Description

Technical Field

[0001] The utility model relates to the technical field of charging piles, in particular to an air duct structure of a charging pile. Background Art

[0002] During the charging process, a large amount of heat is generated by the battery management system and power electronic devices inside the charging pile. The function of the air duct structure of the charging pile is to guide the air flow, so as to effectively dissipate the internal heat. However, in the existing charging piles, a cooling fan is generally directly installed on the outer shell, and the cooling fan is used to blow out the hot air inside the charging pile to achieve the heat dissipation effect. However, there is a lack of rectification and guidance of the air flow, resulting in the air flow being scattered everywhere when passing through the inside of the charging pile, easily generating eddy currents, and thus causing a relatively large wind noise problem. Content of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the utility model provides an air duct structure of a charging pile, which solves the technical problem of relatively large wind noise when the existing charging pile is used.

[0004] To solve the above technical problems, the utility model provides the following technical solutions: an air duct structure of a charging pile, including a charging pile outer shell. Mounting frames are fixedly arranged on both side walls inside the charging pile outer shell. An air inlet plate is fixedly arranged inside the mounting frame. A rectifying component for preventing the air flow from generating eddy currents inside the charging pile outer shell is arranged between the two mounting frames. The rectifying component is installed on the top of the charging pile outer shell. A diversion box is arranged below the diversion component. A diversion fan is installed on the top of the diversion box.

[0005] Preferably, a plurality of rows of air inlet holes are arranged on the air inlet plate.

[0006] Preferably, the rectifying component includes a top plate installed on the top of the charging pile outer shell. Support plates are fixedly arranged on both sides of the bottom of the top plate. A rectifying fan is installed on the support plate.

[0007] Preferably, the rectifying fan is inclined towards the direction of the diversion box, and the two rectifying fans are symmetrically arranged.

[0008] Preferably, four connecting blocks are fixedly arranged inside the air inlet plate. An air inlet dust-proof net is installed on the four connecting blocks. The air inlet dust-proof net is located on the side wall of the charging pile outer shell.

[0009] Preferably, an air outlet dust-proof net is arranged below the diversion box. The air outlet dust-proof net is installed at the bottom of the charging pile outer shell.

[0010] By means of the above technical solutions, the utility model provides an air duct structure of a charging pile, which at least has the following beneficial effects:

[0011] 1. The air duct structure of this charging pile, by setting an air inlet plate, a rectifying component, a diversion box and a diversion fan, when dissipating heat, air enters from both sides, and then the rectifying component rectifies and transitions the air flows in different directions on both sides. Finally, it is blown downward by the diversion fan to achieve the diversion of the air flow. When the air flow in the charging pile housing passes through, eddy currents are not easily generated, thereby improving the noise reduction effect of the air flow.

[0012] 2. The air duct structure of this charging pile, by setting an air inlet dust-proof net and an air outlet dust-proof net, can prevent foreign objects and dust from entering the interior of the charging pile housing, improve the service life of internal electronic devices, and ensure the stable operation of the charging pile.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] With the popularization of electric vehicles, charging piles, as an important part of charging infrastructure, have been widely used. The performance and safety of charging piles directly affect the charging efficiency and user experience of electric vehicles. During the charging process, especially in the fast charging mode, a large amount of heat is generated by the battery management system and power electronic devices inside the charging pile. Without effective heat dissipation measures, the temperature of these devices will rise rapidly, affecting their normal operation and even potentially leading to equipment failures or safety hazards. Therefore, a reasonable air duct structure design is particularly important.

[0024] Based on the technical defect of relatively high wind noise during use in the existing technology, please refer to Figures 1 - 6 The present utility model provides an air duct structure for a charging pile. When the air flow passes through the charging pile housing 1, it is not easy to generate eddy currents, thereby improving the noise reduction effect on the air flow. The air duct structure includes a charging pile housing 1. Mounting frames 2 are fixedly provided on both side walls inside the charging pile housing 1. An air inlet plate 3 is fixedly provided inside the mounting frame 2. A rectifying assembly 6 for preventing the air flow from generating eddy currents inside the charging pile housing 1 is provided between the two mounting frames 2. The rectifying assembly 6 is installed on the top of the charging pile housing 1. A diversion box 7 is provided below the diversion assembly. A diversion fan 8 is installed on the top of the diversion box 7. During use, the rectifying assembly 6 operates to suck in outside air from both sides, then blows the sucked air above the diversion fan 8, and finally, under the action of the diversion fan 8 and the diversion box 7, blows the air downward.

[0025] To ensure that air can enter the charging pile housing 1, multiple rows of air inlet holes 31 are provided on the air inlet plate 3. The air inlet holes 31 can be directly punched on the air inlet plate 3 to form holes. The outer side of the air inlet holes 31 after punching is in an arc shape, which can allow air to enter on the one hand and reduce rainwater infiltration on the other hand.

[0026] To achieve the rectifying effect on the air flow, please refer to Figure 3 The rectifying assembly 6 includes a top plate 61 installed on the top of the charging pile housing 1. Support plates 62 are fixedly provided on both sides of the bottom of the top plate 61. A rectifying fan 63 is installed on the support plates 62. When the rectifying fan 63 operates, the air entering from the air inlet plate 3 is sucked in from the back of the rectifying fan 63, and the entering air is directly blown downward after being rectified by the rectifying fan 63.

[0027] To improve the heat dissipation efficiency, the rectifying fan 63 is inclined towards the direction of the diversion box 7, and the two rectifying fans 63 are symmetrically arranged. The purpose of this design is to increase the air flow speed, thereby accelerating heat dissipation.

[0028] To prevent foreign objects or dust from entering the charging pile housing 1, four connecting blocks 4 are fixedly provided on the inner side of the air inlet plate 3, and an air inlet dust-proof net 5 is installed on the four connecting blocks 4. The air inlet dust-proof net 5 is located on the side wall of the charging pile housing 1; the air inlet dust-proof net 5 can be used to reduce the entry of dust and foreign objects.

[0029] Similarly, to prevent foreign objects or dust from entering the charging pile housing 1, an air outlet dust-proof net 10 is provided below the flow guide box 7, and the air outlet dust-proof net 10 is installed at the bottom of the charging pile housing 1; the air outlet dust-proof net 10 can also be used to reduce the entry of dust and foreign objects.

[0030] As can be seen from the above embodiments: during use, the rectifying fan 63 in the rectifying assembly 6 operates to suck external air from both sides of the charging pile housing 1. After being guided by the air inlet plate 3, the sucked air is then blown above the flow guide fan 8, and finally, under the action of the flow guide fan 8 and the flow guide box 7, the air is blown downward.

[0031] It should be noted that the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, such that a process, method, article or device comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or device.

[0032] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
