Description

Technical Field

[0001] This application relates to the field of non-vehicle charging technology, and in particular to a noise-reducing charging pile. Background Technology

[0002] A charging pile is a power replenishment device that provides electricity to electric vehicles. Its function is similar to that of a gas pump in a gas station. It can be fixed to the ground or wall and installed in public buildings (charging stations, shopping malls, public parking lots, etc.) and residential parking lots. It can charge electric vehicles of various models according to voltage and current.

[0003] In related technologies, a charging pile includes a housing, a charging module, and a cooling fan. The housing has a cavity, and the housing wall has an air inlet and an air outlet, both of which are connected to the cavity. The charging module is placed in the cavity, and the cooling fan is also placed in the cavity to dissipate the heat generated by the charging module in a timely manner.

[0004] Regarding the aforementioned technologies, since the charging module itself also has a fan, the installation of the cooling fan will not only make the charging pile noisier, but also make the charging pile larger in size. Summary of the Invention

[0005] In order to reduce both the noise and size of the charging station, this application provides a noise-reducing charging station.

[0006] The noise-reducing charging pile provided in this application adopts the following technical solution: A noise-reducing charging station includes: The housing is provided with a receiving cavity, an air inlet and an air outlet, and the air inlet and the air outlet are connected to the receiving cavity; The charging module is disposed in the accommodating cavity; A shunt assembly is disposed in the accommodating cavity to enable the multiple charging modules to form multiple independent and non-interfering heat dissipation channels with the air inlet and the air outlet.

[0007] By adopting the above technical solution, due to the setting of the current shunt component, no turbulence will be formed between multiple charging modules. The fan built into the charging module can meet the heat dissipation requirements, thereby reducing the noise of the charging pile, reducing the size of the charging pile, and reducing the manufacturing cost of the charging pile.

[0008] Preferably, the diversion component is a partition plate, which separates the areas where the multiple charging modules communicate with the air inlet and the air outlet to form multiple heat dissipation channels.

[0009] By adopting the above technical solution, compared with the method of connecting the charging module with the air inlet and the air outlet through pipes to form a heat dissipation channel, this design method uses a partition plate to separate the area connected to the charging module with the air inlet and the area connected to the air outlet. This simple structure forms independent and non-interfering heat dissipation channels, thereby reducing noise and further reducing the size of the charging pile.

[0010] Preferably, the area of ​​the air inlet is 1.8 times the air inlet area of ​​the plurality of charging modules, and the area of ​​the air outlet is 2.5 times the air outlet area of ​​the plurality of charging modules.

[0011] By adopting the above technical solutions, noise can be reduced and the charging pile can be made smaller, while achieving more efficient heat dissipation.

[0012] Preferably, the multiple charging modules are divided into multiple groups, and the multiple charging modules in a group are used to cooperate with a charging plug of the charging pile, and a group of charging modules corresponds to a heat dissipation channel.

[0013] By adopting the above technical solution, firstly, the turbulence between the multiple charging modules corresponding to one charging plug is relatively small under the predetermined power. Therefore, the partition plate will separate the multiple charging modules corresponding to the charging plug in a group, which can reduce the turbulence and make the internal structure of the charging pile simpler. Secondly, separating the modules according to the charging plug also facilitates subsequent maintenance work by the staff.

[0014] Preferably, the air inlet and the air outlet are located on two opposite side walls of the housing, and the housing has a main door that opens and closes at the locations of the air inlet and the air outlet; multiple charging modules are stacked.

[0015] By adopting the above technical solution, the main cabinet door can be opened to perform maintenance work on the charging module, and the stacking of multiple charging modules can also make the structure inside the accommodating cavity more compact.

[0016] Preferably, rainproof louvers are provided at the air inlet and the air outlet, and a dustproof net is also provided at the air inlet, with the dustproof net located on the side close to the charging module.

[0017] By adopting the above technical solution, since the heat dissipation channel formed by the air inlet, charging module and air outlet is horizontally distributed, the setting of the rainproof louver can prevent rainwater from falling into the housing cavity. At the same time, the setting of the dustproof net can also prevent dust from entering the housing cavity, thereby better protecting the charging module and other electronic components.

[0018] Preferably, it further includes an input control module and an output control module. The input control module is used to connect an external power source to the charging module, and the output control module is used to connect a charging plug to the charging module. A partition wall is provided within the accommodating cavity, dividing the accommodating cavity into an intermediate component cavity, an air inlet cavity, an air outlet cavity, an input component cavity, and an output component cavity. The intermediate component cavity is for the charging module. The air inlet cavity communicates with the air inlet, and the air outlet cavity communicates with the air outlet. A partition plate is disposed within the air inlet cavity and the air outlet cavity. The input component cavity is for the input control module and is located below the intermediate component cavity, the air inlet cavity, and the air outlet cavity. The output component cavity is for the output control module and is located to the side of the intermediate component cavity, the air inlet cavity, the air outlet cavity, and the input component cavity. An auxiliary door is provided on the housing at the position corresponding to the output component cavity.

[0019] By adopting the above technical solution, firstly, the chambers containing the input control module, charging module, and output control module are not directly connected, so there will be no turbulence between the three modules, thereby further improving the heat dissipation efficiency of the charging module; secondly, since the output control module is frequently plugged into and disconnected from the charging plug, the location of the output control module and the setting of the auxiliary box door also facilitate the maintenance of the charging pile by the staff.

[0020] Preferably, the wiring between the input control module and the charging module passes through the air outlet cavity, and the wiring between the output control module and the charging module also passes through the air outlet cavity; the charging module is provided with a handle on one side of the air inlet cavity.

[0021] By adopting the above technical solution, the wiring arrangement between the three modules and the setting of the handle facilitate the installation and removal of the charging module. At the same time, the number of additional components in the air intake cavity is small, which can maintain sufficient air intake and thus maintain heat dissipation efficiency.

[0022] Preferably, the cavity wall of the air outlet is provided with a wire-passing sealing sleeve, which is used for wiring between the input control module and the output control module and the charging module. The wire-passing sealing sleeve is tapered.

[0023] By adopting the above technical solution, the airflow in the air outlet cavity can be prevented from going to non-air outlet positions, thereby maintaining heat dissipation efficiency. In addition, the shape of the wire sealing sleeve can be adapted to the size of the wire harness during actual installation, thus facilitating the installation and maintenance of the equipment.

[0024] Preferably, the cavity wall further divides the accommodating cavity into a heat-insulating cavity, which is located above the intermediate element cavity; the wiring between the output control module and the charging module passes above the heat-insulating cavity, but bypasses the area directly above the heat-insulating cavity.

[0025] By adopting the above technical solution, the heat is not easily transferred to the charging module when outdoors due to the setting of the heat insulation cavity. At the same time, the wiring bypasses the heat insulation cavity, which can also reduce the heat transferred to the charging module by other components, thereby enabling more efficient heat dissipation for the charging module.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. Due to the design of the current distribution component, no turbulence is generated between multiple charging modules. The fan built into the charging module can meet the heat dissipation requirements, thereby reducing the noise of the charging pile and reducing the size of the charging pile, thus reducing the manufacturing cost of the charging pile. 2. Firstly, the turbulence between multiple charging modules corresponding to a single charging plug is relatively small at a predetermined power. Therefore, the partition plate will separate the multiple charging modules corresponding to the charging plug in a group, which can reduce the impact of turbulence and make the internal structure of the charging pile more concise. Secondly, separating the modules according to the charging plug also facilitates subsequent maintenance work by staff. Attached Figure Description

[0031] The following is in conjunction with the appendix Figure 1-3This application will be described in further detail.

[0032] This application discloses a noise-reducing charging pile. (Refer to...) Figure 1 and Figure 2 The noise-reducing charging pile includes a housing 1, a charging module 2, and a current-distributing component. The housing 1 is roughly rectangular in shape and has a cavity 11, an air inlet 12, and an air outlet 13. The air inlet 12 and the air outlet 13 are connected to the cavity 11. The charging module 2 is located in the cavity 11. The charging module 2 is the core module in the charging pile that converts AC power to DC power and is the main component that generates heat in the charging pile. The current-distributing component is located in the cavity 11. The current-distributing component allows multiple charging modules 2 to form multiple independent and non-interfering heat dissipation channels 3 with the air inlet 12 and the air outlet 13. The multiple heat dissipation channels 3 are not connected to each other, so there is no turbulence between the multiple charging modules 2. The fans built into the charging modules 2 can meet the heat dissipation requirements, thereby reducing the noise of the charging pile and also reducing the size of the charging pile and the manufacturing cost.

[0033] Reference Figure 1 and Figure 2 To make the internal structure of the charging pile simpler, the structure of the diversion component is a partition plate 4. The partition plate 4 separates the areas where multiple charging modules 2 are connected to the air inlet 12, and also separates the areas where multiple charging modules 2 are connected to the air outlet 13, thereby forming multiple heat dissipation channels 3 that do not interfere with each other. In other embodiments, if the simplicity of the structure is not considered, a pipe structure can also be used to connect the charging modules 2 to the air inlet 12 and the air outlet 13.

[0034] In addition, in this embodiment, in order to maintain heat dissipation efficiency, there is a certain proportional relationship between the air intake of the entire charging pile and the air intake of the charging module 2, and between the air output of the entire charging pile and the air output of the charging module 2. Specifically, the area of ​​the air inlet 12 is 1.8 times the air intake area of ​​the multiple charging modules 2, and the area of ​​the air outlet 13 is 2.5 times the air output area of ​​the multiple charging modules 2.

[0035] Reference Figure 1 and Figure 2 Charging piles typically have multiple charging plugs, and each charging plug corresponds to a charging module 2. Under a predetermined power, the turbulence between these charging modules 2 is relatively small. Therefore, in order to maintain the heat dissipation efficiency and keep the internal structure of the charging pile simple, the multiple charging modules 2 are grouped according to the number of corresponding charging plugs. In this embodiment, taking the multiple charging modules 2 as divided into two groups as an example, the partition plate 4 will separate the areas of the two groups of charging modules 2 connected to the air inlet 12 and the air outlet 13, so that one group of charging modules 2 corresponds to one heat dissipation channel 3. At the same time, this separation method also facilitates maintenance work by the staff.

[0036] Reference Figure 1 and Figure 2 To facilitate maintenance, the following configuration is provided: the air inlet 12 and the air outlet 13 are located on two opposite side walls of the housing 1. The housing 1 has a main door 14 installed at the locations of the air inlet 12 and the air outlet 13. Since multiple charging modules 2 are also stacked, the main door 14 can be opened to perform maintenance on the multiple charging modules 2. In addition, because the above distribution makes the heat dissipation channel 3 horizontally arranged, rainproof louvers 15 are provided at the air inlet 12 and the air outlet 13 to prevent rainwater from falling in. At the same time, a dustproof net 16 is also provided at the air inlet 12. The dustproof net 16 is located on the side close to the charging module 2 to prevent dust from falling into the housing cavity 11.

[0037] Reference Figure 1 and Figure 2 In this embodiment, the charging pile also includes an input control module 5 and an output control module 6. The input control module 5 connects to an external power source and the charging module 2, and the output control module 6 connects to a charging plug and the charging module 2. To prevent turbulence between the three modules, a partition wall 17 is provided inside the accommodating cavity 11. The partition wall 17 divides the accommodating cavity 11 into an intermediate element cavity 111, an air inlet cavity 112, an air outlet cavity 113, an input element cavity 114, and an output element cavity 115. The intermediate element cavity 111 is used for the charging module 2, and the air inlet cavity 112 and the output element cavity 115 are connected to the charging module 2. The air inlet 12 is connected, and the air outlet 113 is connected to the air outlet 13. The partition plate 4 is set in the air inlet 112 and the air outlet 113. The input element cavity 114 is set for the input control module 5. The input element cavity 114 is located below the intermediate element cavity 111, the air inlet 112, and the air outlet 113. The output element cavity 115 is set for the output control module 6. The output element cavity 115 is located to the side of the intermediate element cavity 111, the air inlet 112, the air outlet 113, and the input element cavity 114. With the above arrangement, the three modules will not generate turbulence.

[0038] In addition, in this embodiment, considering that the output control module 6 is often connected or disconnected from the charging plug, the housing 1 is provided with an auxiliary door 18 at the position corresponding to the output element cavity 115.

[0039] Reference Figure 1 and Figure 2In order to reduce the negative impact of other components on the air volume of the air outlet cavity 113 and the air volume of the air inlet cavity 112, the wiring between the input control module 5 and the charging module 2 passes through the air outlet cavity 113, and the wiring between the output control module 6 and the charging module 2 also passes through the air outlet cavity 113. However, the charging module 2 is provided with a handle 21 on one side of the air inlet cavity 112, which facilitates the installation and removal of the charging module 2 while maintaining sufficient air volume and air volume, thereby maintaining heat dissipation efficiency.

[0040] In addition, to prevent the wiring from affecting the airflow of the air outlet cavity 113, a wire-passing sealing sleeve 7 is provided on the cavity wall of the air outlet cavity 113. The wire-passing sealing sleeve 7 is used for the wiring between the input control module 5 and the output control module 6 and the charging module 2. This can prevent the airflow of the air outlet cavity 113 from going to the non-air outlet 13 position, thereby maintaining heat dissipation efficiency. At the same time, the wire-passing sealing sleeve 7 is tapered, which also makes it easy to adapt to the size of the wire harness during actual installation, thereby facilitating the installation and maintenance of the equipment.

[0041] Reference Figure 2 and Figure 3 To further prevent external influences on the heat dissipation of the charging module 2, the cavity wall 17 further divides the accommodating cavity 11 into a heat-insulating cavity 116. The heat-insulating cavity 116 is located above the intermediate component cavity 111, so that outdoor heat is not easily transferred to the charging module 2. At the same time, the wiring between the output control module 6 and the charging module 2 passes above the heat-insulating cavity 116, but bypasses the direct top of the heat-insulating cavity 116, so it can also reduce the heat transferred to the charging module 2 by other components, thereby enabling more efficient heat dissipation for the charging module 2.

[0042] The implementation principle of a noise-reducing charging pile in this application embodiment is as follows: due to the setting of the current shunt component, no turbulence is formed between multiple charging modules 2, so the fan built into the charging module 2 can meet the heat dissipation requirements, thereby reducing the noise of the charging pile, reducing the size of the charging pile and reducing the manufacturing cost of the charging pile.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
