Detailed Implementation

[0044] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0045] In the description of this application, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined as "first" or "second" may explicitly or implicitly include one or more features. In the description of this application, "multiple" means two or more, and "at least one" can mean one, two, or more, unless otherwise explicitly specified.

[0046] As an introduction to the embodiments of this application, a charging box is introduced. With the gradual increase in the sales proportion of new energy vehicles and the gradual increase in vehicle charging power, the power requirements for the charging energy dispatching system are also increasing. Simultaneously, the requirements for system heat dissipation are also becoming more stringent. When heat dissipation efficiency decreases, it can lead to a drop in charging power or even damage to components. Large charging stations consist of multiple charging boxes, which are equipped with heat dissipation vents, such as air inlets and outlets, to facilitate heat dissipation of the internal structure. However, during the heat dissipation process, due to the close proximity of the air inlets and outlets, hot air exhausted from the outlet may re-enter the charging box through the air inlet, resulting in hot air recirculation. This leads to poor heat dissipation, reduced heat dissipation efficiency, and consequently, affects charging efficiency.

[0047] In view of the above, embodiments of this application provide a charging box to overcome at least one of the above-mentioned technical problems.

[0048] Please see Figure 1 , Figure 8 and Figure 10 In this embodiment of the application, the charging box includes: a box body 10, multiple module components 20 and multiple air guide covers 30.

[0049] The housing 10 has a receiving cavity 11, and an inlet 12 and an outlet 13 communicating with the receiving cavity 11. The outlet 13 is located on at least one side of the housing 10 in the second direction Y. Multiple module components 20 are disposed within the receiving cavity 11 and connected to the housing 10, and are spaced apart along the second direction Y. Multiple air guide hoods 30 are disposed on at least one side of the housing 10 along the second direction Y and connected to the housing 10. The multiple air guide hoods 30 are arranged around the outlet 13 to guide the gas discharged from the outlet 13.

[0050] It is understood that the housing 10 is provided with a receiving cavity 11, an inlet 12, and an outlet 13. The inlet 12 is connected to the outlet 13 through the receiving cavity 11. When dissipating heat from the multiple module components 20 inside the receiving cavity 11, outside air can enter the receiving cavity 11 through the inlet 12 to absorb heat from the module components 20, thereby cooling the module components 20. The housing 10 can have an outlet 13 on one side along the second direction Y. In this case, the inlet 12 can be located on the other side of the housing 10 along the second direction Y, so that outside air can pass through the interior of the housing 10 along the second direction Y to dissipate heat from the multiple module components 20 arranged along the second direction Y (e.g., Figure 9 The housing 10 can have outlets 13 on both sides along the second direction Y, and the inlet 12 can be located on one side of the housing 10 along the first direction X (e.g., Figure 1 Alternatively, it can be set on one side of the housing 10 along the third direction Z (e.g. Figure 7 Air enters the cavity 11 through inlet 12 and then exits through outlets 13 on both sides of the housing 10 along the second direction Y. Since multiple module components 20 are spaced apart and arranged in an orderly manner along the second direction Y, with their arrangement direction perpendicular to the orientation of inlet 12, the air entering the cavity 11 through inlet 12 can flow between adjacent module components 20, resulting in a large contact area between the air and each module component 20. This allows for sufficient contact between the air and each module component 20, improving heat dissipation. The first direction X, the second direction Y, and the third direction Z intersect; for example, they may be perpendicular to each other. The first direction X is the length direction of the housing 10, the second direction Y is the width direction of the housing 10, and the third direction Z is the height direction of the housing 10.

[0051] After heat exchange between the air and the module assembly 20, the air temperature rises, becoming hot air, which can be discharged from the outlet 13. Due to the close distance between the inlet 12 and the outlet 13, the air velocity at the inlet 12 is high, making it easy for the discharged hot air to converge at the inlet 12 and re-enter the cavity 11, hindering the rapid cooling of the module assembly 20. Therefore, multiple air guide hoods 30 can be installed at the outlet 13. These hoods can be arranged around the outlet 13 (they can be symmetrically arranged or arrayed according to the shape of the outlet 13) to guide the hot air discharged from the outlet 13, allowing it to be discharged further away from the inlet 12. This also acts as a barrier, preventing the hot air from flowing laterally immediately after exiting the outlet 13, reducing the probability of the discharged hot air re-entering the cavity 11 through the inlet 12, and preventing hot air backflow. This ensures good heat dissipation for the multiple module assemblies 20 inside the cavity 11, guaranteeing the charging efficiency of the device.

[0052] Please see Figure 1 , Figure 2 and Figure 3 In conjunction with the above embodiments, in some embodiments, a plurality of air guide hoods 30 disposed on the same side of the housing 10 are spaced apart along the first direction X of the housing 10, and / or, a plurality of air guide hoods 30 disposed on the same side of the housing 10 are spaced apart along the third direction Z of the housing 10.

[0053] It is understandable that multiple air guide hoods 30 are provided on the side of the housing 10 with the outlet 13, and each air guide hood 30 is connected to the housing 10. If the inlet 12 is located on one or both sides of the housing 10 along the first direction X, then the air guide hood 30 can be located on one or both sides of the outlet 13 along the first direction X to guide and block the exhaust hot air, preventing hot air from flowing back from the outlet 13 into the inlet 12 along the first direction X. If the inlet 12 is located on one or both sides of the housing 10 along the third direction Z, then the air guide hood 30 can be located on one or both sides of the outlet 13 along the third direction Z to guide and block the exhaust hot air, preventing hot air from flowing back from the outlet 13 into the inlet 12 along the third direction Z. If inlets 12 are provided on one or both sides of the housing 10 along the first direction X, and also on one or both sides of the housing 10 along the third direction Z, then air guides 30 are provided at the outlet 13 on one or both sides along the first direction X, and on one or both sides along the third direction Z, to guide and block the hot air discharged from the outlet 13, preventing hot air from flowing back from the outlet 13 into the inlets 12 along the first direction X and the third direction Z. This arrangement can improve the heat dissipation efficiency of the module components 20 inside the housing 11 to a certain extent.

[0054] Please see Figure 4 In conjunction with the above embodiments, in some embodiments, the air guide shroud 30 includes a guide plate 31 and a plurality of baffles 32.

[0055] The guide plate 31 is located on one side of the outlet 13 and is connected to the housing 10. Multiple baffles 32 are connected to the guide plate 31 and together with the guide plate 31 form a guide cavity 33, which communicates with the outlet 13. It is understood that the guide plate 31 on the air guide shroud 30 can be an arc-shaped structure. When hot air is discharged from the interior of the outlet 13, the guide plate 31 can guide and block the hot air just discharged from the outlet 13. The baffles 32 connected to both ends of the guide plate 31 can also guide and block the discharged hot air. The hot air just discharged from the edge of the outlet 13 can enter the guide cavity 33, allowing this portion of hot air to flow more concentratedly and preventing it from spreading outwards immediately after being discharged from the outlet 13. This, to a certain extent, prevents hot air from re-entering the interior of the receiving cavity 11, thereby improving the heat dissipation efficiency of the module components 20 within the receiving cavity 11.

[0056] Please see Figure 10 In conjunction with the above embodiments, in some embodiments, the receiving cavity 11 has a first sidewall 111 and a second sidewall 112 spaced apart in the second direction Y, a plurality of module components 20 are disposed between the first sidewall 111 and the second sidewall 112, one of the first sidewall 111 and the second sidewall 112 is provided with an inlet 12, and the other of the first sidewall 111 and the second sidewall 112 is provided with an outlet 13.

[0057] It is understandable that inlets 12 and outlets 13 can be respectively provided on the first sidewall 111 and the second sidewall 112, which are spaced apart along the second direction Y within the receiving cavity 11, so that air can enter and exit the receiving cavity 11 along the second direction Y. At the same time, multiple module components 20 are disposed between the first sidewall 111 and the second sidewall 112. That is to say, multiple module components 20, inlets 12 and outlets 13 can be arranged approximately along the second direction Y. This arrangement can minimize the change in the airflow direction, so that the air has a high flow velocity and can quickly remove the heat from the module components 20, thereby improving the heat dissipation effect.

[0058] Please see Figure 9 , Figure 11 , Figure 12 and Figure 13In conjunction with the above embodiments, in some embodiments, the charging box includes at least one isolation component 40. At least one isolation component 40 is disposed within the receiving cavity 11 and divides the receiving cavity 11 into a plurality of flow channels 114, each flow channel 114 being connected to an inlet 12 and an outlet 13 respectively, and each flow channel 114 having at least one module component 20 disposed inside.

[0059] Understandably, one or more isolation components 40 are installed inside the receiving cavity 11 to divide the receiving cavity 11 into multiple flow channels 114. When air enters the interior of the housing 10 from the inlet 12, it can enter each flow channel 114 separately, and the air in the corresponding flow channel 114 is then discharged from the outlet 13. Since one or more module components 20 are installed inside each flow channel 114, the air flowing in the flow channel 114 can dissipate heat from the corresponding module component 20. Each flow channel 114 is independent and will not interfere with each other during the heat dissipation process. Therefore, the hot air formed in one flow channel 114 in contact with the corresponding module component 20 will not affect the module components 20 in other flow channels 114, which can reduce the impact of the hot air inside the receiving cavity 11 on other module components 20. Therefore, this configuration allows multiple module components 20 to operate independently without interfering with each other during heat dissipation. The air in each flow channel 114 blows air onto only a small number of module components 20 for heat dissipation, enabling each module component 20 in the flow channel 114 to be cooled quickly and improving heat dissipation efficiency.

[0060] Please see Figure 9 and Figure 11 In conjunction with the above embodiments, in some embodiments, the isolation component 40 includes a first partition 41, a second partition 42, and a third partition 43.

[0061] A first partition 41 is disposed on one side of at least one module assembly 20 along the third direction Z of the housing 10 and is connected to one of the first sidewall 111 and the second sidewall 112. A second partition 42 is disposed between two adjacent module assemblies 20 and is connected to the first partition 41. A third partition 43 is disposed on one side of at least one module assembly 20 along the third direction Z and is connected to the side of the second partition 42 opposite to the first partition 41. The side of the third partition 43 opposite to the second partition 42 is connected to the other of the first sidewall 111 and the second sidewall 112.

[0062] It is understood that the first partition 41, the second partition 42, and the third partition 43 of the isolation component 40 can all be flat plate structures. The first partition 41 and the third partition 43 are connected to the first sidewall 111 and the second sidewall 112, respectively, so that the three partitions can form a "Z" shape structure and remain fixed, dividing the receiving cavity 11 into multiple flow channels 114. This arrangement can ensure that multiple module components 20 are arranged at intervals along the second direction Y, while also isolating multiple module components 20 from each other, preventing the hot air generated by one part of the module components 20 from affecting the other part of the module components 20, and improving the heat dissipation efficiency of the module components 20.

[0063] Please see Figure 5 , Figure 6 , Figure 7 and Figure 8 In conjunction with the above embodiments, in some embodiments, the receiving cavity 11 has a first sidewall 111 and a second sidewall 112 spaced apart in a second direction Y, and a third sidewall 113 disposed between the first sidewall 111 and the second sidewall 112. A plurality of module components 20 are disposed between the first sidewall 111 and the second sidewall 112, and located on one side of the third sidewall 113. Both the first sidewall 111 and the second sidewall 112 are provided with outlets 13, and the third sidewall 113 is provided with an inlet 12.

[0064] It is understandable that outlets 13 can be provided on both the first sidewall 111 and the second sidewall 112 of the receiving cavity 11, and an inlet 12 can be provided on the third sidewall 113. The third sidewall 113 is located between the first sidewall 111 and the second sidewall 112. The third sidewall 113 can be located on one side of the housing 10 along the first direction X, or on one side of the housing 10 along the third direction Z. This ensures that the direction of air entry is perpendicular to the direction in which the multiple module components 20 are arranged within the receiving cavity 11. This allows the air entering the receiving cavity 11 to flow between adjacent module components 20, increasing the contact area with the module components 20 and improving heat dissipation efficiency. Simultaneously, the air entering the receiving cavity 11 will be discharged in two opposite directions. That is, the air is split within the receiving cavity 11; some air blows heat to some module components 20 in one direction, while the other part blows heat to other module components 20 in the other direction. This configuration reduces the number of module components 20 in the airflow direction within the cavity 11, allowing for faster processing of one or more module components 20 in one direction.

[0065] Please see Figure 15 and Figure 17In conjunction with the above embodiments, in some embodiments, the charging box includes a plurality of boxes 10, which are spaced apart along a first direction X. The inlets 12 on two adjacent boxes 10 have the same orientation, and the outlets 13 on two adjacent boxes 10 have the same orientation.

[0066] It is understandable that when the charging box includes multiple boxes 10, the multiple boxes 10 can be arranged at intervals along the first direction X. The inlet 12 of each box 10 has the same orientation, and the outlet 13 also has the same orientation. This allows the distance between the outlet 13 of each box 10 and the inlet 12 of the adjacent box 10 to be relatively large. Since the corresponding outlet 13 of each box 10 has the same orientation, the hot air discharged from the outlet 13 is not likely to enter the interior of the box 10 from the inlet 12 of the adjacent box 10. This ensures that the discharged hot air will not affect other boxes 10 and will not enter the interior of the receiving cavity 11 of other boxes 10, thus ensuring that there is no interference between two adjacent boxes 10.

[0067] Please see Figure 14 and Figure 16 In conjunction with the above embodiments, in some embodiments, the charging box includes a plurality of boxes 10, which are spaced apart along the second direction Y, and the corresponding outlets 13 on two adjacent boxes 10 have opposite orientations.

[0068] Understandably, when multiple enclosures 10 are arranged in the charging box, they can be spaced apart along the second direction Y. This allows the outlet 13 of each enclosure 10 to be far from the inlet 12 of the adjacent enclosure 10, preventing hot air from entering the interior of the adjacent enclosure 10. Simultaneously, the outlet 13 of each enclosure 10 can be arranged in opposite directions to the outlet 13 of the adjacent enclosure 10, causing the exhaust air's force to cancel each other out. The exhaust air flows through the space between adjacent enclosures 10, preventing it from entering the adjacent enclosures and thus avoiding any impact on the adjacent enclosures 10.

[0069] A charging device includes the charging box described above. This charging device possesses all the technical features and beneficial effects of the charging box, which will not be elaborated further here.
