[0044] The core of this application is to disclose a charging module to reduce the heat dissipation cost of a charging pile.

[0045] Another core of the present application is to disclose a charging pile including the above-mentioned charging module.

[0046] The following is an explanation of the embodiments with reference to the accompanying drawings. In addition, the embodiments shown below do not limit the contents of the utility model described in the claims. In addition, the entire contents of the construction represented by the following embodiments are not limited to those necessary as solutions to the utility model described in the claims. It should be noted that, for ease of description, only the parts related to the utility model are shown in the accompanying drawings. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other.

[0047] Combination Figure 2 and Figure 3 The charging module disclosed in the present application includes a charging body, a heat dissipation back plate and a heat dissipation fan. A first air duct is arranged on the charging body, the heat dissipation back plate is arranged on the first side of the charging body, and a second air duct is arranged. The second air duct extends in a direction away from the charging body. The heat dissipation fan is arranged on the charging body and can blow air into the first air duct and the second air duct.

[0048] In the present application, the setting of the first air duct on each charging module enables each cooling fan to take away the heat inside its own charging body by blowing air into the first air duct, and the setting of the second air duct enables each cooling fan to blow air to the environment around its own charging module, and then blow air to the charging modules around the charging module.

[0049] It is understood by those skilled in the art that the charging module is usually used in the charging pile and other equipment. Figure 1 or Figure 5 The layout structure shown in the figure is arranged in a regular array. Figure 1 In the embodiment, the charging modules are stacked, and at least two charging modules are arranged at intervals on each layer, and the heat dissipation back plate of one of the two charging modules on the same layer is arranged toward the charging body of the other; Figure 5 In the embodiment, the charging modules are stacked and arranged, and at least two charging modules are arranged at intervals in each column, and the heat dissipation back plate of one of the two charging modules in the same column is arranged toward the charging body of the other.

[0050] For the sake of convenience, two adjacent charging modules are defined as the first module 1 and the second module 2, and the heat dissipation backplane of the first module 1 is arranged facing the second side of the charging body of the second module 2, the charging body of the first module 1 is the first body 1-1, the heat dissipation fan of the first module 1 is the first fan 1-3, the heat dissipation backplane of the first module 1 is the first backplane 1-4, the charging body of the second module 2 is the second body 2-1, the heat dissipation fan of the second module 2 is the second fan 2-3, and the heat dissipation backplane of the second module 2 is the second backplane 2-4. Then, the first fan 1-3 can blow air to dissipate heat to the first body 1-1 through the first air duct of the first module 1, and blow air to dissipate heat to the second body 2-1 through the second air duct of the first module 1.

[0051] Compared with the prior art, the present application simultaneously arranges the first air duct and the second air duct on the charging module, so that the cooling fan of each charging module can blow air to the interior of each charging module itself and the outer surface of the adjacent charging module to dissipate heat, and drive the flow of air in the charging pile, thereby achieving a better heat dissipation effect. This can reduce the arrangement of a part of the fans used to dissipate heat on the outside of the charging module, save heat dissipation costs, and reduce the volume of the charging pile.

[0052] Specifically, combined Figure 8 and Fig. 9 A ventilation hole 1-6 is provided on the heat dissipation back plate, one end of the ventilation hole 1-6 is connected to the first air duct, and the other end extends away from the charging body. The ventilation hole 1-6 serves as the above-mentioned second air duct to realize the flow of air to the surrounding environment of the charging module, especially the second body 2-1.

[0053] In one embodiment, the ventilation holes 1-6 on the first back plate 1-4 are opened toward the direction of the second body 2-1, so that the heat dissipation airflow blown out by the first fan 1-3 can be directly blown to the outer wall of the second body 2-1 after passing through the second air duct.

[0054] Combination Figure 4 and Fig. 9 The ventilation holes 1-6 are usually multiple ventilation holes 1-6. Specifically, the multiple ventilation holes 1-6 can be opened at at least one position of the heat dissipation back plate, or the ventilation holes 1-6 can be evenly opened at various positions of the heat dissipation back plate. Figure 8-Figure 11 The ventilation holes 1-6 may specifically be circular holes, elongated holes, or elliptical holes (not shown in the figure).

[0055] Taking the case where the multiple ventilation holes 1-6 are only opened at one end of the heat dissipation back plate, when the charging module is used in the charging pile Figure 1 When the layout structure shown in the figure is arranged, the end of the heat dissipation back plate with ventilation holes 1-6 is arranged above the end without ventilation holes 1-6 (that is, using Fig.10 The heat dissipation airflow blown out from the ventilation holes 1-6 on the first module 1 can automatically sink to a certain angle under the action of gravity, especially when the heat dissipation airflow blown out by the first fan 1-3 is cold air (see below), and thus the first fan 1-3 can perform a certain amount of spraying heat dissipation on the outer surface of the middle and lower part of the second main body 2-1.

[0056] In addition, the second air duct can also be formed by a pipe. By setting a pipe at the air outlet of the first fan 1-3 and arranging the outlet of the pipe at the second main body 2-1, the second main body 2-1 can also be cooled by air, which will not be repeated here.

[0057] In order to optimize the heat dissipation effect on the charging body, in some embodiments, the charging module also includes a water-cooled radiator (not shown in the figure), which is arranged on the charging body and located at the air outlet of the cooling fan, so that the heat dissipation path of the cooling fan passes through the water-cooled radiator, and then the cooling fan can blow out cold air to enhance the heat dissipation effect on the charging body.

[0058] Furthermore, there is usually a certain gap between each charging module to ensure the heat dissipation effect between each charging module and the environment. Figure 1 and Figure 2 When the layout structure shown in the figure is arranged, in order to effectively guide the heat dissipation airflow led out from the ventilation holes 1-6 to the adjacent charging modules, Figure 4 A guide plate 1-5 is also provided on the side of the heat dissipation back plate facing away from the charging body. The guide plate 1-5 forms a guide air duct, which is connected to the second air duct. The heat dissipation airflow flowing out of the second air duct can further flow to the charging body of the adjacent charging module along the guide of the guide air duct, thereby ensuring the heat dissipation effect on the adjacent charging modules.

[0059] Since cold air will automatically sink under the action of gravity, in order to ensure the cooling effect of the heat dissipation airflow on the adjacent charging modules, Figure 4 , when the charging module adopts Figure 1 and Figure 2 When arranging the layout structure shown in the figure, the guide flow channel can be arranged to extend (incline) away from the ground, so that after the heat dissipation airflow flows out of the guide air duct, it can directly exchange heat with the higher part of the adjacent charging module, and under the action of gravity, heat is exchanged with the lower part of the adjacent charging module in sequence from top to bottom.

[0060] It can be understood by those skilled in the art that, since the thickness of the heat dissipation back plate is usually thin, the axes of the ventilation holes 1-6 are usually arranged perpendicular to the plate surface of the heat dissipation back plate. Therefore, in some embodiments, the ventilation holes 1-6 are arranged horizontally, and the guide air duct has an angle with the axes of the ventilation holes 1-6 and is inclined away from the ground.

[0061] In order to facilitate full contact and heat exchange with the heat dissipation airflow of the adjacent charging module (first module 1), a guide groove can be set on the second side of the charging body. The guide groove allows the airflow to pass through and guides the heat dissipation airflow to ensure that the heat dissipation airflow can flow on the surface of the charging body (second body 2-1) as much as possible to achieve sufficient heat exchange.

[0062] Specifically, in some embodiments, a plurality of guide fins 2-5 are protruding from the second side of the charging body, and the guide fins 2-5 extend along the extension direction of the charging body, and the above-mentioned guide grooves are formed between two adjacent guide fins 2-5. Figure 5 and Figure 6 When the layout structure shown in is arranged, the guide groove can extend in the horizontal direction.

[0063] The above-mentioned guide groove can also be a groove on the second side surface of the charging body itself, which will not be described in detail here.

[0064] Furthermore, the guide fins 2-5 can also be made of metal materials and welded to the surface of the second side of the charging body to serve as heat dissipation fins to increase the heat exchange area with the heat dissipation airflow and improve the heat exchange effect.

[0065] In a specific embodiment disclosed in the present application, a guide groove is provided on the second side of the charging body, and a guide plate 1-5 is provided on the heat dissipation back plate. Figure 4 After the heat dissipation airflow flows out from the ventilation holes 1-6, it flows obliquely upward along the guide air duct until it contacts the top of the charging body of the adjacent charging module. Under the action of gravity, the heat dissipation airflow flows along the guide groove and fully exchanges heat with the charging body of the adjacent charging module.

[0066] Combination Figure 2 and Figure 3 In order to ensure the cooling effect of the cooling fan on the charging body, the charging module also includes a radiator (the radiator of the first module 1 is the first radiator 1-2, and the cooling back plate of the second module 2 is the second back plate 2-3). For example, the radiator can be a cooling fin disposed between the charging body and the cooling back plate to increase the heat exchange area of ​​the charging body. The first air duct is formed by the cooling fin, the cooling back plate and the charging body. Each cooling fan can blow air into one or more first air ducts.

[0067] Combination Fig.12 and Fig.13 The charging pile disclosed in the present application includes a cabinet 3 and a plurality of the above-mentioned charging modules, the charging modules are arranged at intervals in the cabinet 3, and two adjacent charging modules in the charging pile are defined as a first module 1 and a second module 2, respectively, and the heat dissipation back plate (first back plate 1-4) of the first module 1 is arranged facing the second side of the charging body (second body 2-1) of the second module 2, and the outlet end of the second air duct of the first module 1 faces the second side of the charging body of the second module 2.

[0068] Combination Fig.12 and Fig.13When the cooling fan is started, the cooling fan (first fan 1-3) of the first module 1 can dissipate heat to its own charging body through the first air duct, and blow air to the outer surface of the charging body of the second module 2 through the second air duct to dissipate heat, thereby ensuring the heat dissipation effect.

[0069] Compared with the prior art, the charging pile disclosed in the present application has better heat dissipation effect and lower cost, can reduce the additional fan arrangement, reduce the heat dissipation power and cost, improve the charging efficiency of the entire pile, and can reduce the height size of the charging pile.

[0070] Specifically, when the charging module is used in the cabinet 3 Figure 5 When the layout structure shown in FIG. 1 (the first module 1 is arranged above the second module 2) is arranged, as shown in FIG. Figure 6 As shown, the second air duct can extend along the connecting direction of the first module 1 and the second module 2, that is, extend along the vertical direction. When the heat dissipation airflow is blown out from the ventilation holes 1-6, under the action of the blowing direction and gravity, the heat dissipation airflow can directly exchange heat with the second side surface of the second main body 2-1.

[0071] When the charging module is used in cabinet 3 Figure 1 and Figure 2 When the layout structure shown in FIG. 1 is arranged (the first module 1 is arranged on one side of the second module 2 in the horizontal direction), taking two charging modules in each row as an example, combined with Fig.12 and Fig.13 , the two sides of the charging body of the second module 2 can receive heat dissipation from the first fan 1-3 and the second fan 2-3 respectively, and because the heat dissipation airflow sinks under the action of gravity, the charging module located at the bottom in the vertical direction can receive heat dissipation from the heat dissipation airflow blown by the heat dissipation fan located above. In this embodiment, a guide plate connected to the second air duct and tilted upward is preferably provided on the heat dissipation back plate to facilitate guiding the heat dissipation airflow to the top of the second body 2-1 for heat dissipation.

[0072] Furthermore, in order to be able to dissipate heat from the charging module (e.g. Fig.13 The first module 1) in the cabinet is used for heat dissipation. A top fan 4 can be provided on the top of the cabinet 3. Fig.14 and Fig.15 The top fan 4 is only arranged above the charging module located at the end (close to the second side of the charging module) where the charging body can only receive heat dissipation from its own cooling fan, so that each charging module in the cabinet 3 can fully exchange heat. Compared with the prior art, which requires one or more top fans 4 to be arranged above each column of charging modules, this embodiment effectively reduces the number of top fans 4 and saves heat dissipation costs.

[0073] The above description of the disclosed embodiments enables professionals and technicians in the field to implement or use the present application. Various modifications to these embodiments will be apparent to professionals and technicians in the field, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application. The specific technical means in some embodiments can be combined in part or in whole into another embodiment, provided that they are not explicitly excluded by another embodiment. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest range consistent with the principles and novel features disclosed herein.
