Description

Technical Field

[0001] This disclosure pertains to the field of new energy technology, and specifically relates to a charging pile. Background Technology

[0002] With the booming development of the new energy industry, the charging pile manufacturing industry is experiencing rapid growth.

[0003] A typical charging station includes a cabinet, a protection module, a power module, a distribution module, and an output module. These modules are electrically connected sequentially and installed within the cabinet. The input terminal of the protection module is connected to AC power, and the output terminal of the output module is electrically connected to the charging gun head via a charging cable, outputting DC power to charge new energy vehicles. During use, each module within the charging station generates heat.

[0004] However, current charging stations typically only dissipate heat from the power module, which can cause heat generated by other modules to accumulate inside the cabinet. This can lead to electrical disconnection between modules due to high temperatures, resulting in poor stability of the charging station. Summary of the Invention

Detailed Implementation

[0074] To make the objectives, technical solutions, and advantages of this disclosure clearer, the embodiments of this disclosure will be further described in detail below with reference to the accompanying drawings.

[0075] Currently, the new energy vehicle industry is booming, and the charging pile manufacturing industry is also developing and growing rapidly to provide complete charging infrastructure for new energy vehicles. Currently, charging piles typically include a pile body, charging cables, and charging nozzles. The pile body is the component used to connect to the mains power and convert AC power to DC power. The charging nozzles are electrically connected to the output module of the pile body via charging cables, thereby charging the new energy vehicle. Specifically, the pile body includes a cabinet, a protection module, a power module, a distribution module, and an output module, which are installed inside the cabinet. The input terminal of the protection module is connected to the mains power, and the output terminal of the protection module is connected to the input terminal of the power module. The protection module is used to disconnect the electrical connection between the cabinet and the mains power in the event of overcurrent or short circuit. The power module is used to convert AC power to DC power. The distribution module, also known as a PDU (Power Distribution Unit), has its input terminal electrically connected to the output terminal of the power module. Its output terminal is electrically connected to the input terminals of multiple output units. The distribution module is responsible for rationally distributing the total input power to each output module in use according to charging demand. During the use of a charging station, each module inside the station generates heat. However, current charging stations typically only dissipate heat from the power module. This can cause heat generated by other modules to accumulate inside the cabinet, potentially leading to electrical disconnection between modules due to high temperatures, resulting in poor stability of the charging station.

[0076] To address the aforementioned issues, this disclosure provides a charging pile. Figure 1 and Figure 2 This is a schematic diagram of the charging station as a whole. Figure 3 and Figure 4 See the schematic diagram of the internal structure of the charging station. Figures 1 to 4 The pile body includes a cabinet 1, an exhaust fan 2, a power module 3, a distribution module 4, an output module 5, and a protection module 6.

[0077] Among them, such as Figure 1 and Figure 2As shown, the cabinet 1 has a hollow cubic structure, and the outer wall of the cabinet 1 has an air inlet 100 and an air outlet 200. Specifically, the cabinet 1 has a first side wall 111 and a second side wall 112 opposite to each other. The air outlet 200 is located on the second side wall 112, and the second air inlet 102 is located on the first side wall 111. The air inlet 100 and the air outlet 200 are respectively connected to the receiving cavity inside the cabinet 1, which houses the power module 3, the distribution module 4, the output module 5, and the protection module 6. The cabinet 1 can be made of insulating materials, such as engineering plastics, or it can be made of non-insulating materials, such as alloy steel or aluminum alloy. This embodiment does not limit the material used. For example, the first air inlet 101 and the second air inlet 102 can both be rectangular openings. This reduces the processing difficulty of the first air inlet 101 and the second air inlet 102.

[0078] Among them, see Figure 1 The exhaust fan 2 is located at the air outlet 200. In operation, the exhaust fan 2 draws air out of the cabinet 1 through the air outlet 200. It's easy to understand that as the air inside the cabinet is expelled through the air outlet 200, a brief negative pressure is created inside the cabinet 1. Under this negative pressure, external air is drawn into the cabinet 1 through the air inlet 100, thus forming an airflow channel from the air inlet 100 to the air outlet 200 inside the cabinet 1. In some examples, the exhaust fan 2 is installed inside the cabinet 1. In this way, the cabinet 1 can protect the exhaust fan 2, thereby extending its service life.

[0079] Among them, such as Figure 3 and Figure 4 As shown, the power module 3, distribution module 4, output module 5 and protection module 6 are located on the gas flow channel between the air inlet 100 and the air outlet 200.

[0080] Using the technical solution provided in this embodiment, under the action of the exhaust fan 2, a gas flow channel can be formed between the air inlet 100 and the air outlet 200 of the cabinet 1. The power module 3, distribution module 4, output module 5 and protection module 6 are respectively arranged on the gas flow channel, so that the gas can perform heat exchange on the power module 3, distribution module 4, output module 5 and protection module 6 respectively and carry the heat out of the cabinet 1 through the air outlet 200, realize heat dissipation of multiple modules inside the charging pile, thereby avoiding heat accumulation inside the cabinet 1 and improving the stability of the charging pile.

[0081] In some possible embodiments, multiple gas flow channels are formed between the air inlet 100 and the air outlet 200.

[0082] In some examples, cabinet 1 has two air inlets. For example... Figure 1 and Figure 2As shown, the outer wall of the cabinet 1 is provided with a first air inlet 101 and a second air inlet 102, which are respectively connected to the air outlet 200. A first gas flow channel is formed between the first air inlet 101 and the air outlet 200, and the distribution module 4, the output module 5, and the protection module 6 are respectively located on the first gas flow channel. A second gas flow channel is formed between the second air inlet 102 and the air outlet 200, and the power module 3 is located on the second gas flow channel.

[0083] By setting two air inlets on the cabinet 1, the airflow into the cabinet 1 can be increased, thereby improving the overall heat dissipation efficiency of the charging pile. Furthermore, since the power module 3 is the module that generates the most heat within the charging pile, placing the distribution module 4, output module 5, and protection module 6 on the first airflow channel, and separately placing the power module 3 on the second airflow channel, prevents the hotter air passing through the power module 3 from flowing through the distribution module 4, output module 5, and protection module 6, thus improving the heat dissipation efficiency of each module.

[0084] In some instances, cabinet 1 has two air inlets. For example... Figure 1 and Figure 2 As shown, the outer wall of cabinet 1 is provided with a first air inlet 101 and a second air inlet 102. Further, see... Figure 5 and Figure 6 The cabinet 1 contains a partition 12, which has a connecting area 120. The partition 12 divides the interior of the cabinet 1 into a first receiving cavity 01 and a second receiving cavity 02. Further, as... Figure 5 As shown, the air inlet 100 includes a first air inlet 101 and a second air inlet 102. The first air inlet 101 corresponds to the first receiving cavity 01, and the second air inlet 102 and the air outlet 200 correspond to the second receiving cavity 02, respectively.

[0085] In implementation, a first gas flow channel is formed between the first air inlet 101, the connecting area 120, and the air outlet 200, and a second gas flow channel is formed between the second air inlet 102 and the air outlet 200. (See also...) Figure 13 and combined Figure 1 and Figure 2 ( Figure 13 (This is a simulation diagram of a charging pile provided in an embodiment of the present disclosure). A first gas flow channel is formed between the first air inlet 101 and the air outlet 200, and a second gas flow channel is formed between the second air inlet 102 and the air outlet 200.

[0086] Optionally, see Figure 6 The first air inlet 101 is located at the bottom of the first receiving cavity 01, and the connecting area 120 is located above the first air inlet 101.

[0087] like Figure 6As shown, the first receiving cavity 01 accommodates the distribution module 4, the output module 5, and the protection module 6. The distribution module 4, the output module 5, and the protection module 6 are arranged at intervals in the first receiving cavity 01 in a vertically downward direction, and the distribution module 4, the output module 5, and the protection module 6 are arranged between the first air inlet 101 and the connecting area 120.

[0088] Optionally, see Figure 7 The charging pile may include multiple power modules 3, which are arranged vertically at intervals within the second receiving cavity 02. A gap 01a exists between each pair of adjacent power modules 3, and this gap 01a is arranged opposite to the connecting area 120.

[0089] For example, the charging pile may include two power modules 3. The connecting region 120 includes a first connecting region 121 and a second connecting region 122, and the first connecting region 121 is located below the second connecting region 122. The second connecting region 122 is connected to the gap 01a between the two power modules 3.

[0090] Optionally, the connecting area 120 includes a plurality of elongated openings, which are also used for cable routing. The number and specific size of these elongated openings can be set by those skilled in the art according to actual needs, and this embodiment does not limit this.

[0091] The specific structure of cabinet 1 is described below:

[0092] In some examples, cabinet 1 includes cabinet body 11 and partition 12.

[0093] like Figure 9 As shown ( Figure 9 (This is a schematic diagram of the structure of a cabinet disclosed herein.) The cabinet 1 includes a cabinet body 11 and a partition 12. The cabinet body 11 has a hollow cubic structure. The partition 12 is located inside the cabinet body 11 and is fixedly connected to the cabinet body 11. The partition 12 divides the internal accommodating space of the cabinet body 11 into multiple parts.

[0094] Specifically, see Figure 9 The cabinet body 11 includes a frame 1101, a first door 1102, a second door 1103, and a third door 1104. The frame 1101 has a hollow cubic structure, and door mounting positions are respectively provided on the front wall and the two opposite side walls of the frame 1101. The first door 1102 is located in the door mounting position on the front wall, and the second door 1103 and the third door 1104 are respectively located in the door mounting positions on the two side walls. The first door 1102, the second door 1103, and the third door 1104 are rotatably connected to the frame 1101. Please refer to [link / reference]. Figure 1 , Figure 2 and Figure 9 The first air inlet 101 is located on the front wall of the frame 1101, the second air inlet 102 is located on the third door 1104, and the air outlet 200 is located on the second door 1103. The exhaust fan 2 is located inside the second door 1103 and at the air outlet 200.

[0095] In practice, the first door 1102, the second door 1103, and the third door 1104 can all rotate relative to the frame 1101. When the first door 1102, the second door 1103, and the third door 1104 are all located in their respective door mounting positions, the cabinet body 11 forms a relatively closed cubic structure. Under the action of the exhaust fan 2, the gas inside the cabinet 1 is discharged to the outside of the cabinet 1 through the air outlet 200, and a relative negative pressure is formed inside the cabinet 1. Under the action of this negative pressure, the gas enters the inside of the cabinet 1 through the first air inlet 101 and the second air inlet 102.

[0096] In addition, it is easy to understand that when any one of the first door 1102, the second door 1103 and the third door 1104 is not located in the corresponding door installation position, technicians can observe the internal condition of the cabinet body 11 through the corresponding door installation position, thereby inspecting the internal modules.

[0097] For example, see Figure 9 The door mounting position on the side wall is located on the side of the side wall away from the main wall.

[0098] For example, see Figure 9 The second door body 1103 and the third door body 1104 are respectively rotatably connected to the side of the corresponding door body mounting position away from the main wall.

[0099] Furthermore, such as Figure 9 As shown, a charging cable connector 113 and a charging head holder 114 are provided on the side wall of frame 1101. The charging cable connector 113 connects the interior and exterior of cabinet 1 and is used for the charging cable of the charging pile to pass through. In implementation, one end of the charging cable is connected to the output module 5 (…). Figure 9 (Not shown) Connected, the other end of the gun wire extends out of the cabinet 1 through the gun wire connector 113, and the other end of the gun wire is connected to the gun head. See also Figure 9 The gun head placement rack 114 is located outside the side wall of the frame 1101. The shape and size of the gun head placement rack 114 are adapted to the gun head of the charging pile. The gun head placement rack 114 accommodates the gun head to prevent the gun head from hanging outside the cabinet 1 or contacting the ground.

[0100] For example, see Figure 9 A gun wire connector 113 and a gun head holder 114 are respectively installed on the two side walls of the frame 1101.

[0101] Please continue reading Figure 9 The spacer 12 is installed inside the frame 1101, dividing the interior of the frame 1101 into multiple receiving cavities. Specifically, as shown... Figure 9 As shown, the isolation member 12 includes a baffle 1201, a first mounting plate 1202, and a second mounting plate 1203. The two ends of the baffle 1201 are respectively connected to the two side walls of the frame 1101, and the first mounting plate 1202 and the second mounting plate 1203 are respectively located between the baffle 1201 and the back wall of the frame 1101. (See also...) Figure 5 And refer to Figure 9 A first receiving cavity 01 is formed between the baffle 1201, the top wall of the frame 1101, the bottom wall of the frame 1101, and the two side walls of the frame 1101, and a second receiving cavity 02 is formed between the baffle 1201, the top wall of the frame 1101, the bottom wall of the frame 1101, the first mounting plate 1202, and the second mounting plate 1203.

[0102] Optionally, such as Figure 9 As shown, the frame 1101 has multiple mounting columns inside, with both ends of the columns connected to the top and bottom walls of the frame 1101, respectively, and the columns are also connected to the baffle 1201. This improves the connection stability between the baffle 1201 and the frame 1101.

[0103] Optionally, such as Figure 9 As shown, the baffle 1201 is arranged parallel to the back wall of the frame 1101, and the first mounting plate 1202 and the second mounting plate 1203 are respectively arranged perpendicular to the back wall of the frame 1101. In this way, the internal space of the cabinet 1 can be more square.

[0104] Further, see Figure 4 See also Figure 9 The distribution module 4 and output module 5 are located within the first receiving cavity 01, and are respectively fixedly connected to the baffle 1201. The power module 3 and protection module 6 are located within the second receiving cavity 02, and are respectively fixedly connected to the baffle 1201. It is easy to understand that when the charging pile is in operation, AC current flows through the power module 3 and protection module 6, while DC current flows through the distribution module 4 and output module 5. Therefore, placing the power module 3 and protection module 6 in the second receiving cavity 02 and the distribution module 4 and output module 5 in the first receiving cavity 01 effectively separates the AC and DC modules. This improves the convenience of subsequent maintenance of the charging pile.

[0105] In one example, the first receiving cavity 01 is not connected to the second receiving cavity 02. The cabinet 1 has two air outlets 200. The first air inlet 101 is connected to the first receiving cavity 01, and the second air inlet 102 is connected to the second receiving cavity 02. One of the air outlets 200 is connected to the first receiving cavity 01, and the other air outlet 200 is connected to the second receiving cavity 02.

[0106] In another example, the first air inlet 101 is connected to the first receiving cavity 01, the cabinet 1 has only one air outlet 200, and the second air inlet 102 and the air outlet 200 are respectively connected to the second receiving cavity 02.

[0107] See in this example. Figure 5 And refer to Figure 9 The baffle 1201 serves as a component that separates the first receiving cavity 01 and the second receiving cavity 02. The baffle 1201 may have a through hole structure, through which the first receiving cavity 01 and the second receiving cavity 02 can be connected.

[0108] In implementation, such as Figure 4 As shown, a first gas flow channel is formed between the first air inlet 101 and the air outlet 200. Gas enters the first receiving cavity 01 through the first air inlet 101 and comes into contact with the distribution module 4 and the output module 5 respectively. Subsequently, the gas enters the second receiving cavity 02 through the aforementioned through-hole structure and comes into contact with the protection module 6. Finally, the gas leaves the cabinet 1 through the air outlet 200. A second gas flow channel is formed between the second air inlet 102 and the air outlet 200. Gas enters the second receiving cavity 02 through the second air inlet 102 and comes into contact with the power module 3. Subsequently, the gas leaves the cabinet 1 through the air outlet 200. In the above process, heat exchange occurs when the gas comes into contact with the power module 3, the distribution module 4, the output module 5, and the protection module 6, carrying away the heat generated by these modules, thereby achieving heat dissipation of the charging cabinet.

[0109] In some possible embodiments, there may be multiple connected regions between the first receiving cavity 01 and the second receiving cavity 02.

[0110] In some examples, such as Figure 6 As shown, the first receiving cavity 01 and the second receiving cavity 02 have a first connecting region 121 and a second connecting region 122.

[0111] See Figure 11 ( Figure 11(This is a partial schematic diagram of baffle 1201). Baffle 1201 has multiple first through holes 1201a and multiple second through holes 1201b. The multiple first through holes 1201a form the aforementioned first connecting region 121, and the multiple second through holes 1201b form the aforementioned second connecting region 122. The first connecting region 121 and the second connecting region 122 are distributed at intervals along the height direction of the cabinet 1. Furthermore, the first air inlet 101 and the second connecting region 122 are distributed on both sides of the first connecting region 121. Specifically, as shown... Figure 11 As shown, the baffle 1201 is a rectangular plate structure. The bottom side of the baffle 1201 has a first region and a second region. The first region and the second region are spaced apart in the horizontal direction of the baffle 1201, and the first region and the second region have the same height in the vertical direction. Each of the first region and the second region has multiple first through holes 1201a, and the multiple first through holes 1201a are distributed in a matrix.

[0112] For example, the first through hole 1201a is an oblong hole, and the multiple first through holes 1201a in the first region and the second region are distributed in a 10*5 matrix.

[0113] Furthermore, such as Figure 11 As shown, the bottom side of the baffle 1201 also has a third region, which is located on the side of the second region away from the first region, and is located between the second region and the bottom edge of the baffle 1201. The third region has a plurality of first through holes 1201a, which are arranged at intervals along the vertical direction.

[0114] In some examples, the allocation module 4 and the output module 5 are arranged at intervals.

[0115] like Figure 6 As shown, the output module 5 is located between the first air inlet 101 and the first connecting area 121, and the output module 5 is connected to the baffle 1201. The distribution module 4 is located between the first connecting area 121 and the second connecting area 122, and the distribution module 4 is connected to the baffle 1201.

[0116] In implementation, see Figure 4 , Figure 6 and Figure 9Gas enters the cabinet 1 through the first air inlet 101 and then enters the first receiving cavity 01 through the connecting hole 131. The gas flows upward and exchanges heat with the output module 5. Part of the gas after heat exchange with the output module 5 enters the second receiving cavity 02 through the first connecting area 121, while the other part of the gas continues to flow upward and exchanges heat with the distribution module 4. The gas after heat exchange with the distribution module 4 enters the second receiving cavity 02 through the second connecting area 122. Finally, the gas entering the second receiving cavity 02 exchanges heat with the power module 3 and the protection module 6 respectively, and then leaves the cabinet 1 through the air outlet 200.

[0117] In some examples, power module 3 and protection module 6 are arranged at intervals.

[0118] See Figure 10 ( Figure 10 (This is a schematic diagram of the structure of the isolation member 12). The isolation member 12 also includes a first partition 1204. The first partition 1204 is arranged horizontally and is located between the first mounting plate 1202 and the second mounting plate 1203. Both ends of the first partition 1204 are connected to the first mounting plate 1202 and the second mounting plate 1203, respectively.

[0119] Among them, see Figure 10 The second receiving cavity 02 includes a first receiving area 021 and a second receiving area 022. The first receiving area 021 is located below the first partition 1204, and the second receiving area 022 is located above the first partition 1204. See also Figure 10 And refer to Figure 4 ( Figure 4 The first mounting plate 1202 is omitted. The first accommodating area 021 accommodates the protection module 6, and the second accommodating area 022 accommodates the power module 3.

[0120] In some examples, the protection module 6 is arranged opposite to the first connected region 121.

[0121] like Figure 10 As shown, the first connected region 121 is connected to the first accommodating region 021. (See Figure 121 for details.) Figure 7 And refer to Figure 10 The protection module 6 is located within the first accommodating area 021, and at least a portion of the protection module 6 is arranged opposite to the first connecting area 121.

[0122] In implementation, referring to the example above, a portion of the gas that has undergone heat exchange with the output module 5 enters the second receiving cavity 02 through the first connecting region 121. Subsequently, this portion of gas comes into contact with the protection module 6 and undergoes heat exchange. Finally, this portion of gas leaves the cabinet 1 through the air outlet 200. In this way, the gas passing through the second connecting region 122 can contact the protection module 6, thereby achieving heat dissipation for the protection module 6.

[0123] Optionally, see Figure 10 The isolation component 12 also includes a second partition 1205, which is vertically arranged and located between the first mounting plate 1202 and the second mounting plate 1203, and is connected to the baffle 1201. A first receiving area 021 is formed between the second partition 1205 and the first mounting plate 1202. This improves the operational stability of the protection module 6.

[0124] Further, see Figure 10 and Figure 11 Referring to the example above, a clearance area is formed between the second partition 1205 and the second mounting plate 1203. This clearance area is connected to the first through hole 1201a in the second and third regions of the baffle 1201. Thus, gas entering the second receiving cavity 02 through the first through hole 1201a in the first region can contact the side wall of the protection module 6 near the baffle 1201, and gas entering the second receiving cavity 02 through the first through hole 1201a in the second and third regions can contact the wall of the protection module 6 near the bottom wall of the second mounting plate 1203 and the frame 1101. This increases the contact area between the gas and the protection module 6, improving the heat dissipation efficiency of the protection module 6.

[0125] In some possible embodiments, the charging station includes multiple power modules 3.

[0126] There is a gap 01a between each pair of adjacent power modules 3, and the gap 01a is connected to the second connected region 122.

[0127] In some examples, the charging station includes two power modules 3.

[0128] like Figure 10 As shown, the isolation member 12 includes two first partitions 1204, which are arranged vertically at intervals. A second receiving area 022 is formed above each first partition 1204; that is, the second receiving cavity 02 has two second receiving areas 022, which are arranged vertically at intervals. Each second receiving area 022 accommodates one power module 3. Further, see... Figure 7When the two power modules 3 are respectively installed in the second receiving cavity 02, there is a gap 01a between the two power modules 3, which is connected to the second connecting region 122.

[0129] In implementation, referring to the example above, a portion of the gas that has undergone heat exchange with the output module 5 enters the second receiving cavity 02 through the first connecting region 121, while another portion of the gas continues to flow upward. Subsequently, another portion of the gas contacts the distribution module 4 and undergoes heat exchange. The gas that has undergone heat exchange with the distribution module 4 enters the second receiving cavity 02 through the second connecting region 122 and undergoes heat exchange with the outer walls of the two power modules 3. Finally, this portion of the gas leaves the cabinet 1 through the air outlet 200. In this way, the gas flowing to the gap 01a through the second connecting region 122 can again contact the outer wall of the power module 3, achieving secondary heat dissipation for the power module 3.

[0130] Of course, the number of power modules 3 in the charging pile can also be greater than two. For example, the charging pile includes three or four power modules 3. Correspondingly, the baffle 1201 has multiple second connecting regions 122 (not shown). The multiple second connecting regions 122 are all located on the side of the first connecting region 121 away from the first air inlet 101, and the multiple second connecting regions 122 are distributed at intervals along the vertical direction. Each second connecting region 122 is connected to a gap 01a.

[0131] The specific structure of the first gas flow channel is described below:

[0132] In some possible embodiments, the first air inlet 101 may be located on the bottom wall of the cabinet 1.

[0133] In practice, the gas temperature at the bottom wall of cabinet 1 is relatively low. By placing the first air inlet 101 at the bottom wall of cabinet 1, the temperature of the gas entering the cabinet 1 from the first air inlet 101 is lower. In other words, the temperature of the gas flowing in the first gas channel is lower. As a result, the gas in the first gas channel can carry away more heat when it comes into contact with the distribution module 4, the output module 5 and the protection module 6, thereby improving the heat dissipation efficiency of the distribution module 4, the output module 5 and the protection module 6.

[0134] Specifically, such as Figure 9 As shown, the first air inlet 101 is located on the front wall of the frame 1101, and is located on the side of the front wall near the bottom wall.

[0135] In some examples, cabinet 1 also includes shelf 13.

[0136] See Figure 9The shelf 13 is located within the frame 1101, and is spaced apart from the bottom wall of the frame 1101, and is connected to the frame 1101. The first air inlet 101 is located on the front wall of the frame 1101, and is located on the side of the front wall closer to the bottom wall. The height of the shelf 13 is greater than the height of the first air inlet 101. Further, the shelf 13 includes a first part and a second part, wherein the first part is located within the first receiving cavity 01, and the second part is located within the second receiving cavity 02. The first part of the shelf 13 has a plurality of connecting holes 131, which are respectively connected to the first receiving cavity 01 and the first air inlet 101.

[0137] By adopting the technical solution provided in this embodiment, the frame plate 13 can separate the first accommodating cavity 01 from the first air inlet 101, thereby preventing gas carrying water vapor from directly entering the first accommodating cavity 01, thus improving the stability of the charging pile in use.

[0138] For example, see Figure 9 The shelf 13 is set parallel to the bottom wall of the cabinet 1.

[0139] For example, see Figure 9 The number of connecting holes 131 can be two, and the shape of the connecting holes 131 can be square.

[0140] Optionally, in some examples, the height of the air outlet 200 may be greater than the height of the first air inlet 101.

[0141] like Figure 1 and Figure 2 As shown, the cabinet 1 has a first sidewall 111 and a second sidewall 112. The air outlet 200 is located on the second sidewall 112 of the cabinet 1, and the air outlet 200 is located on the side of the second sidewall 112 away from the bottom wall of the cabinet 1. The bottom height of the air outlet 200 is greater than the top height of the first air inlet 101. In implementation, the gas temperature rises after heat exchange with the module, and correspondingly, the gas density decreases. By setting the height of the air outlet 200 to be greater than the height of the first air inlet 101, the first gas flow channel conforms to the gas flow trend, thereby reducing the rated power required by the exhaust fan 2 and lowering the cost.

[0142] The specific structure of the second gas flow channel is described below:

[0143] In some possible embodiments, the second gas flow channel is a straight air duct.

[0144] like Figures 1 to 3As shown, cabinet 1 has a first sidewall 111 and a second sidewall 112 facing each other. A second air inlet 102 is located on the first sidewall 111, and an air outlet 200 is located on the second sidewall 112 of cabinet 1. The second air inlet 102 and the air outlet 200 are arranged opposite each other. See also... Figure 5 And refer to Figure 9 The second air inlet 102 is located on the third door 1104, and the air outlet 200 is located on the second door 1103. When the second door 1103 and the third door 1104 are respectively located in their corresponding door installation positions, the second air inlet 102 and the air outlet 200 are arranged opposite to each other.

[0145] Specifically, see Figure 3 The charging station includes two power modules 3, which are located inside the cabinet 1 and connected to it. These two power modules 3 are positioned between the second air inlet 102 and the air outlet 200, respectively.

[0146] In practice, when the charging pile is in operation, the power module 3 generates a large amount of heat. By setting the two ends of the first gas flow channel (i.e., the second air inlet 102 and the air outlet 200) to be arranged opposite each other, and placing the two power modules 3 between the second air inlet 102 and the air outlet 200 respectively, the gas flow rate through the power module 3 per unit time can be maximized, thereby improving the heat dissipation efficiency of the power module 3.

[0147] Further, see Figure 2 The first sidewall 111 has two second air inlets 102, which are respectively arranged opposite to the air outlet 200, and each second air inlet 102 and the air outlet 200 respectively form a second gas flow channel. Each power module 3 is located between the air outlet 200 and a second air inlet 102.

[0148] In some possible embodiments, the charging station also includes a flow guide tube 7.

[0149] See Figure 8 and refer to Figure 5 as well as Figure 9 As shown, the power module 3 is located inside the cabinet 1, and the second air inlet 102 is located on the third door 1104, with the height of the power module 3 being greater than the height of the second air inlet 102. A clearance area exists between the second mounting plate 1203 and the third door 1104, which is used to accommodate the air guide tube 7.

[0150] Specifically, see Figure 8 The guide tube 7 has a cubic structure. The top wall and side wall of the guide tube 7 are open. The side wall opening of the guide tube is connected to the second air inlet 102. The top wall opening of the guide tube 7 is arranged opposite to the power module 3.

[0151] During implementation, external air may carry water vapor. Before this relatively humid air enters the cabinet 1 through the second air inlet 102, it will first enter the interior of the guide tube 7 and come into contact with the side wall of the guide tube 7 away from the second air inlet 102. When in contact, some of the water vapor can condense into water droplets and adhere to the inside of the guide tube 7, thereby reducing the humidity of the air entering the cabinet 1 and improving the service life of the power module 3.

[0152] For example, the charging pile includes two air guide tubes 7, the side wall opening of each air guide tube is connected to a second air inlet 102, and the top wall opening of each air guide tube 7 is arranged opposite to a power module 3.

[0153] In some possible embodiments, the charging station also includes multiple filters.

[0154] For example, the filter element is a 50PPI polyurethane dust filter.

[0155] In some examples, such as Figure 2 As shown, the filter covers the first air inlet 101 and two second air inlets 102.

[0156] In some examples, such as Figure 9 As shown, the filter element covers two connecting holes 131.

[0157] In some possible embodiments, the charging station also includes louvered fans.

[0158] See Figure 1 And refer to Figure 9 The louvered fan is located inside the air outlet 200 and is connected to the second door 1103.

[0159] By adopting the technical solution provided in this embodiment, filters are installed in the air inlet and connecting holes to prevent dust and other impurities from entering the cabinet 1, and to block moisture in the gas, thus improving the dustproof and waterproof performance of the charging pile. By installing louvers in the air outlet 200, rainwater is prevented from directly contacting the exhaust fan 2, thereby extending the service life of the exhaust fan 2.

[0160] In some possible embodiments, the charging station includes multiple exhaust fans 2.

[0161] See Figure 4 And refer to Figure 7 The charging pile includes four exhaust fans 2, which are arranged at intervals in the vertical wind direction. From top to bottom, the first exhaust fan 2 and the third exhaust fan 2 are respectively arranged opposite to two power modules 3, the second exhaust fan 2 is arranged opposite to the gap 01a between the two power modules 3, and the fourth exhaust fan 2 is arranged opposite to the protection module 6.

[0162] In some possible embodiments, the charging station also includes a charging cable and a charging head (both not shown), wherein one end of the charging cable is electrically connected to the output module 5, the other end of the charging cable extends outside the cabinet 1, and the charging head is electrically connected to the other end of the charging cable.

[0163] The following is an introduction to the various modules of the charging pile and their electrical connections:

[0164] I. Protection Module 6

[0165] Protection module 6, also known as a molded case circuit breaker, is the module that provides protection for the charging pile.

[0166] like Figure 7 As shown, the protection module 6 is installed in the second receiving cavity 02 of the cabinet 1. The protection module 6 includes a main body, three input copper busbars, and three output copper busbars (only two are shown in the figure). The three input copper busbars and three output copper busbars are electrically connected to the main body, and the three input copper busbars are electrically connected to the three live wires of the mains power supply. Each output copper busbar is electrically connected to one input copper busbar. The main body is used to disconnect the electrical connection between each input copper busbar and its corresponding output copper busbar in the event of overcurrent or circuit breaking.

[0167] Further, see Figure 7 Each output copper busbar has four mounting holes.

[0168] II. Power Module 3

[0169] Power module 3 is a module in the charging station used to convert AC power to DC power.

[0170] See Figure 7 The charging pile includes two power modules 3, and each power module 3 includes two power units, that is, the charging pile includes four power units. Each power unit is electrically connected to a corresponding mounting hole on one of the three output copper busbars, that is, each power unit is electrically connected to the three live wires of the mains power.

[0171] III. Allocation Module 4

[0172] Distribution module 4 is the module used for power distribution in the charging pile.

[0173] See Figure 4 The top wall of the distribution module 4 has eight first connecting copper busbars protruding from it. These eight first connecting copper busbars include four first positive connecting copper busbars and four first negative connecting copper busbars. Each first positive connecting copper busbar is electrically connected to the positive output terminal of a power unit, and each first negative connecting copper busbar is electrically connected to the positive output terminal of a power unit.

[0174] Further, see Figure 6The bottom wall of the distribution module 4 protrudes with eight second connecting copper busbars, including four second positive connecting copper busbars and four second negative connecting copper busbars. Each second positive connecting copper busbar and each second negative connecting copper busbar forms an output module connection position. That is, the distribution module 4 has four output module connection positions. In implementation, the distribution module 4 can distribute the power input to the power module 3 according to the number of output modules 5 connected to the output module connection positions and the number of output modules 5 in operation.

[0175] IV. Output Module 5

[0176] Output module 5, also known as DC output module, is a module in the charging pile used to output DC power to external devices.

[0177] See Figure 12 The output module 5 includes a positive output copper busbar 51, a negative output copper busbar 52, a shunt 53, a fuse 54, two high-voltage DC contactors 55, a positive output terminal 56, and a negative output terminal 57.

[0178] One end of the positive output copper busbar 51 is electrically connected to the second positive connection copper busbar, and one end of the negative output copper busbar 52 is electrically connected to the second negative connection copper busbar. A shunt 53 and a high-voltage DC contactor 55 are arranged on the positive output copper busbar 51, and a fuse 54 and a high-voltage DC contactor 55 are arranged on the negative output copper busbar 52. The positive output terminal 56 is electrically connected to the other end of the positive output copper busbar 51 and the positive line in the gun wire, respectively, and the negative output terminal 57 is electrically connected to the other end of the negative output copper busbar 52 and the negative line in the gun wire, respectively.

[0179] For example, the charging station includes two output modules 5, see Figure 9 Referring to the example above, the two output modules 5 are respectively arranged below the first region and the second region of the baffle 1201.

[0180] The technical solutions provided in this disclosure have at least the following beneficial effects:

[0181] This embodiment of the disclosure provides a charging pile in which a power module 3, a distribution module 4, an output module 5, and a protection module 6 are respectively located on the gas flow channel between the air inlet 100 and the air outlet 200. In this way, under the action of the exhaust fan 2, a gas flow channel can be formed between the air inlet 100 and the air outlet 200 of the cabinet 1. The power module 3, distribution module 4, output module 5, and protection module 6 are respectively arranged on this gas flow channel, allowing the gas to exchange heat with the power module 3, distribution module 4, output module 5, and protection module 6, and then carry the heat out of the cabinet 1 through the air outlet 200. This achieves heat dissipation for the various modules inside the charging pile, thereby preventing heat accumulation inside the cabinet 1 and improving the operational stability of the charging pile.
