[0023] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

Figure 2 It is a structural schematic diagram of the ventilation and heat dissipation structure of the charging device of the present invention in the second state.

Figures 1-2 In the figure, the front door and the rear door of the housing are opened respectively so as to see the internal structure of the ventilation and heat dissipation structure of the charging device of the present invention. Figure 3 In the embodiment, the rear of the housing is closed to facilitate observation of the structure provided on the rear door. Figure 5 It is a transverse cross-sectional schematic diagram of the air inlet and outlet of the ventilation and heat dissipation structure of the charging device of the present invention. Figure 6 This is a vertical cross-sectional diagram of the ventilation and heat dissipation structure of the charging device of the utility model. Figures 1 to 6 The ventilation and heat dissipation structure of the charging device of the present invention is described as follows.

[0025] like Figures 1 to 6 ,especially Figure 1 5-6, the ventilation and heat dissipation structure of the charging device of the present invention includes a shell 10, and a plurality of heat dissipation modules 20 layered inside the shell 10; a plurality of independent air inlet and outlet channels 30 are formed inside the shell 10, and each independent air inlet and outlet channel 30 corresponds to a layer of heat dissipation modules 20; the module air inlet 21, the module air outlet 22 and the built-in radiator (not shown) of each heat dissipation module 20 are arranged in a straight line to form a straight ventilation channel 31 respectively.

[0026] In a preferred embodiment of the present invention, the charging device may be a charging pile, so its housing may be a charging pile housing. The heat dissipation module 20 may be an IP65 module. When the charging device is other equipment, the heat dissipation module 20 may be any module that needs to dissipate heat and is provided in the charging device. Figure 1 As shown, 18 IP65 modules are divided into three layers and arranged inside the housing 10, with 6 IP65 modules arranged in each layer. Figure 6 As shown, three independent air inlet and outlet channels 30 are formed, and each independent air inlet and outlet channel 30 corresponds to a heat dissipation layer of 6 IP65 modules. Figures 5-6 As shown, the module air inlet 21, module air outlet 22, and built-in radiator (not shown) of each module 20 requiring heat dissipation are arranged in a straight line to form a linear ventilation channel 31. In a preferred embodiment of the present invention, any suitable mounting and sealing structure can be used to install the modules 20 requiring heat dissipation in layers, thereby forming multiple independent air inlet and outlet channels 30.

[0027] In the present invention, by arranging the modules that need heat dissipation in layers and providing independent air inlet and outlet channels for each layer of modules that need heat dissipation, the air volume at the air inlet can be increased, heat accumulation at the air inlet can be avoided, and the modules that need heat dissipation can be helped to quickly absorb air. The module air inlet, module air outlet and built-in radiator of each module that needs heat dissipation are arranged in a straight line to form a straight ventilation channel respectively, which can make the air inlet and outlet smoother, facilitate the rapid discharge of heat, and thus effectively reduce the temperature of the modules that need heat dissipation and the internal temperature of the charging device.

[0028] In a preferred embodiment of the present invention, Figure 1 As shown, a plurality of intermediate partitions 11 are provided inside the housing 10, and six heat dissipation modules 20 are provided on each intermediate partition 11, and at least one horizontal baffle 12 is provided in front of each intermediate partition 11. Figure 1 As shown, a horizontal baffle 12 and a side baffle 14 can be respectively provided in front of and on the side of the middle partition 11. The first side of the housing 10 (eg Figure 1The housing air inlet 13 is provided on the left side of the housing 10. The housing air inlet 13 is provided with an air inlet louver 131. The height of the housing air inlet 13 is adapted to the overall height of the heat dissipation module 20. The module air inlet 21 of each heat dissipation module 20 is facing the second side of the housing 10 (as shown). Figure 1 The front side shown in FIG), the module air outlet 22 is facing the third side of the housing 10 (as shown in FIG). Figures 2-3 The first side of the housing 10 is perpendicular to the second side of the housing 10 and the third side of the housing 10. Figure 1 ,as well as Figures 5-6 It can be seen that the middle partition 11 and the horizontal baffle 12 form multiple independent air inlet and outlet channels 30 within the shell 10, and each layer of modules 20 that need to dissipate heat is accommodated in an independent air inlet and outlet channel 30. Since the module air inlet 21 of each module 20 that needs to dissipate heat faces the second side of the shell 10, and the module air outlet 22 faces the third side of the shell 10, and the first side of the shell 10 is perpendicular to the second side and the third side of the shell 10, the module air inlet 21, module air outlet 22, and built-in radiator of each module 20 that needs to dissipate heat are arranged in a straight line to form a linear ventilation channel 31. In this preferred embodiment, the modules 20 that need to dissipate heat are fixedly divided into corresponding layers by internal partition support, and each layer is an independent side air inlet channel, which can increase the air volume at the air inlet, avoid heat accumulation at the air inlet, and facilitate rapid air intake of the modules that need to dissipate heat, thereby reducing the internal temperature of the modules that need to dissipate heat and the internal temperature of the shell. Furthermore, the module air inlet 21, module air outlet 22 and built-in radiator of each module 20 requiring heat dissipation are arranged in a straight line to form a straight ventilation channel 31 respectively, which can quickly discharge heat from the shell to ensure the normal operating temperature of the shell.

[0029] Further Figure 6 As shown, the first half 111 of the middle partition 11, which is away from the first side of the housing 10 (i.e., the side close to the air inlet), is provided with multiple openings 112, while the second half 113 close to the first side of the housing 10 is not provided with any openings, i.e., it is configured as a closed plate. This design of having no openings on the end close to the air inlet and openings on the end away from the air inlet is conducive to temperature balance between the modules on the same layer, and avoids too large a temperature difference. Preferably, as Figure 6 As shown, multiple rows of openings 112 are arranged equidistantly.

[0030] Further Figure 2As shown, each module 20 requiring heat dissipation is covered with a module cover 25, and an opening is provided on the module cover 25 for the module air outlet 22 to dissipate air. By adding the module cover 25, the module air inlet 21, the module air outlet 22, and the built-in radiator of the module 20 requiring heat dissipation can form a straight air inlet and outlet channel, allowing air in and out more smoothly, thereby quickly dissipating heat, further helping to reduce module temperature and further increasing module safety and stability.

[0031] Further Figure 3 As shown, the housing 10 is a rectangular housing, including a front door panel, left and right side panels and a rear door panel 15. Figures 1 to 6 As shown, the front and rear door panels are both removable. Of course, in other preferred embodiments of the present invention, the housing 10 can be in any suitable shape, such as cylindrical, square, etc., and the front door panel, left and right side panels and rear door panel 15 can be partially removable. A plurality of rear door covers 16 are provided on the rear door panel 15 of the housing 10 corresponding to the number of layers of the modules 20 to be cooled. The air outlet spacing of each rear door cover 16 is designed according to the number of modules 20 to be cooled on each layer, that is, Figure 3 As shown, three rear door covers are designed for three layers of modules 20 requiring heat dissipation, and six air outlet intervals are designed for each layer of six modules 20 requiring heat dissipation. In a preferred embodiment of the present invention, the rear door cover 16 is semicircular in shape, which facilitates smooth airflow. This design allows for quick and convenient heat dissipation, further reducing module temperature and noise, preferably by several decibels.
