Description

Technical Field

[0001] This application relates to the field of wall-mounted DC charging piles, and in particular to a charging pile with high heat dissipation effect. Background Technology

[0002] The charging module inside the charging pile cannot achieve 100% energy conversion efficiency in the process of converting AC power to DC power. Currently, the efficiency of the mainstream modules in the industry is about 95%, which means that 5% of the electrical energy will be lost in the form of heat. As the charging speed increases, the current and voltage will also increase accordingly, resulting in an increase in the power of the charging module and thus generating more heat. Therefore, heat dissipation devices are usually installed inside the charging pile.

[0003] In existing technologies, heat dissipation devices are usually installed on the side wall of the charging pile cabinet. The heat dissipation device is not designed independently and dissipates heat to the entire interior of the cabinet. The interior of the cabinet is cooled by the air driven by the cooling fan. This reduces the amount of heat dissipation from the cooling fan to the charging module. Other parts of the cabinet do not often require a large amount of heat dissipation and can meet the heat dissipation needs through natural cooling. As a result, the heat dissipation of the cooling fan will be unreasonable.

[0004] Therefore, the cooling fan inside the charging pile needs to be designed separately so that it can cool the charging module independently, thereby improving the cooling efficiency of the charging module. Utility Model Content

[0005] A charging station with high heat dissipation efficiency is provided so that the cooling fan can separately dissipate heat from the charging module.

[0006] The above-mentioned objective of this application is achieved through the following technical solution:

[0007] A charging pile with high heat dissipation effect includes a cabinet. The cabinet is provided with a partition mechanism. The partition mechanism includes a first partition component, which divides the cabinet into a module cavity and a panel cavity. A charging module is installed separately in the module cavity. Heat dissipation components are installed on both sides of the module cavity. The heat dissipation components include a cooling fan and louvers.

[0008] By adopting the above technical solution, the charging module is installed separately in the module cavity. The first partition separates the module cavity, and the heat dissipation components on both sides of the module cavity dissipate heat from the charging module inside the module cavity. This ensures that the heat dissipation flow of the heat dissipation components is directed towards the charging module and does not flow to other parts of the charging pile. As a result, the heat dissipation components do not have the phenomenon of unreasonable heat dissipation distribution, which improves the heat dissipation efficiency of the charging module. It can meet the heat dissipation requirements of the charging pile with fewer cooling fans and significantly reduce the operating noise.

[0009] Optionally, the partition mechanism further includes a second partition component, which is parallel to the first partition component, located on the side of the first partition component facing the module cavity, and is fixedly connected to the cabinet.

[0010] By adopting the above technical solution, a second partition is provided between the cabinet and the side wall to separate them. This forms a flow channel perpendicular to the heat dissipation component between the first partition and the second partition, allowing the heat dissipation component to dissipate heat along the flow channel between the first partition and the second partition. The charging module is located in the flow channel, thereby increasing the amount of heat dissipation from the heat dissipation component to the charging module.

[0011] Optionally, the first partition assembly includes a first partition plate, and a raised first limiting piece is provided on the side of the first partition plate facing the module cavity. The second partition assembly includes a second partition plate, and a raised second limiting piece is provided on the side of the second partition plate facing the module cavity. The two side walls of the charging module abut against the first limiting piece and the second limiting piece, respectively.

[0012] By adopting the above technical solution, when the heat dissipation component dissipates heat in the flow channel, if there are gaps between the first partition and the second partition and the two side walls of the charging module, the heat dissipation airflow will partially pass through the gaps. Therefore, by having the first partition and the second partition abut against the two side walls of the charging module, the heat dissipation airflow passes entirely through the charging module, thereby improving the heat dissipation efficiency of the charging module.

[0013] Optionally, the cooling fan, charging module, and louvers are all located on the same horizontal plane within the module cavity.

[0014] By adopting the above technical solution, the airflow blown out by the cooling fan can act directly on the charging module, thereby forming a sealed space on both sides of the charging module. The entire charging module can be cooled by the cooling fan, which improves the heat dissipation efficiency of the charging module.

[0015] Optionally, it also includes a control panel, which has a through-hole groove at the same position as the first partition. A sealing gasket is installed on the first partition and is located inside the through-hole groove.

[0016] By adopting the above technical solution, the wires for connecting the control panel and the charging module pass through the wire groove, and the sealing gasket is located in the wire groove to limit the wires. At the same time, the sealing gasket can prevent the airflow of the heat dissipation component from flowing from the wire groove to the panel cavity, so that the airflow of the heat dissipation component acts independently on the charging module.

[0017] Optionally, the sealing gasket is made of an elastic material, and its two sides are respectively engaged with the first partition and the control panel.

[0018] By adopting the above technical solution, the sealing gasket can be removed during wire installation, making wire installation more convenient. After the wire connection is completed, the sealing gasket can be inserted into the wire groove and engaged with the first partition and control panel. The detachable connection of the sealing gasket improves the efficiency of wire connection.

[0019] Optionally, the first limiting piece separates the charging module from the control panel, and the second limiting piece separates the charging module from the cabinet.

[0020] By adopting the above technical solution, the control panel and the charging module are separated by a first limiting plate, and the cabinet and the charging module are separated by a second limiting plate, which prevents the heat of the charging module from being directly transferred to the surface of the cabinet and the control panel, thereby improving the safety performance of the control panel.

[0021] Optionally, the number of cooling fans is multiple, and the multiple cooling fans are arranged vertically; the number of charging modules is multiple, and the multiple charging modules are arranged vertically within the module cavity.

[0022] By adopting the above technical solution, the vertical arrangement can ensure that each charging module can be evenly contacted by the air duct of the cooling fan, avoiding some modules not being in contact with the air duct of the cooling fan and thus overheating and affecting the overall performance, making the heat dissipation of the charging module more uniform and efficient.

[0023] In summary, this application has at least the following beneficial effects:

[0024] 1. By adding a first partition and a second partition, a flow channel for installing the charging module is formed between the first partition and the second partition. This allows the air ducts of the heat dissipation devices on both sides of the module cavity to pass completely over the charging module within the flow channel. The air ducts of the heat dissipation devices will not flow to other places, and the charging module will be cooled separately, thus improving the heat dissipation efficiency of the charging module.

[0031] The following section provides a more detailed description, in conjunction with the accompanying diagrams:

[0032] As attached Figure 1 and attached Figure 2 As shown, a charging pile with high heat dissipation effect includes a cabinet 1, a partition mechanism 2, and a heat dissipation component 3.

[0033] The cabinet 1 includes a first side door 11 and a second side door 12. The first side door 11 and the second side door 12 are parallel to each other and are respectively hinged to the two side walls of the cabinet 1 via hinges.

[0034] The heat dissipation component 3 includes louvers 31 and cooling fans 32. The cooling fans 32 and louvers 31 are respectively embedded in the first side door 11 and the second side door 12. The cooling fans 32 are located on the side of the first side door 11 facing the cabinet 1. There are six cooling fans 32, and all six cooling fans 32 are arranged vertically.

[0035] The partition mechanism 2 includes a first partition component 21 and a second partition component 22. The first partition component 21 divides the cabinet 1 into a module cavity 13 and a panel cavity 16, and the module cavity 13 is located between the first side door 11 and the second side door 12.

[0036] As attached Figure 2 and attached Figure 3 As shown, the module cavity 13 is provided with two installation chambers 14, which are arranged vertically. Each installation chamber 14 is provided with a mounting seat 141. The two installation chambers 14 are separated by the mounting seat 141. The upper end of the upper installation chamber 14 is also equipped with a mounting seat 141, and the lower end of the lower installation chamber 14 is also equipped with a mounting seat 141.

[0037] There are three mounting seats 141, all of which are arranged vertically. The upper mounting seat 141 abuts against the inner wall of the top of the cabinet 1, and the lower mounting seat 141 abuts against the inner wall of the bottom of the cabinet 1.

[0038] Two charging modules 15 are installed in each of the two installation chambers 14, and the two charging modules 15 are detachably connected to the two mounting bases 141, which facilitates the inspection and replacement of the charging modules 15. A handle 151 is installed on the side of the two charging modules 15 facing away from the module cavity 13, which facilitates the installation and removal of the charging modules 15 and improves the efficiency of the installation and removal of the charging modules 15.

[0039] As attached Figure 2 and attached Figure 4 As shown, the first partition assembly 21 includes a first partition 211, which is fixedly connected to the inner side wall of the cabinet 1. The first partition 211 has a raised first limiting piece 212 on the side facing the module cavity 13, and the side of the first limiting piece 212 facing the module cavity 13 abuts against the charging module unit 14.

[0040] As attached Figure 2 and attached Figure 5 As shown, a control panel 213 is installed on the side of the first partition 211 facing the panel cavity 16. The control panel 213 and the charging module 15 are separated by a first limiting piece 212 to prevent the heat of the charging module 15 from being directly transferred to the surface of the control panel 213. The control panel 213 and the first partition 211 are both provided with a through-hole 23 at the same position. The through-hole 23 is for the wires that connect the control panel 213 and the charging module 15 to pass through.

[0041] A sealing gasket 24 is also installed on the first partition 211. The shape of the sealing gasket 24 matches the wire groove 23. The sealing gasket 24 is made of elastic material, but here it is made of rubber. The sealing gasket 24 is located inside the wire groove 23. The side of the sealing gasket 24 facing the module cavity 13 is engaged with the first partition 211, and the side of the sealing gasket 24 facing the panel cavity 16 is engaged with the control panel 213.

[0042] After the wires pass through the cable groove 23 and connect the charging module 15 and the control panel 213 in sequence, the sealing gasket 24 is pressed into the cable groove 23 to fix the wires. At the same time, the sealing gasket 24 can prevent the airflow of the heat dissipation component 3 from flowing from the cable groove 23 to the panel cavity 16, so that the airflow of the heat dissipation component 3 can act independently on the charging module 15.

[0043] As attached Figure 2 and attached Figure 4 As shown, the second partition assembly 22 includes a second partition 221, which is parallel to the first partition 211. The second partition 221 is located on the side of the first partition 211 facing the module cavity 13, and the side of the second partition 221 facing away from the first partition 211 is fixedly connected to the inner wall of the cabinet 1.

[0044] The second partition 221 has a raised second limiting piece 222 on the side facing the module cavity 13. The side of the second limiting piece 222 facing the module cavity 13 abuts against the charging module 15. The second limiting piece 222 separates the cabinet 1 from the charging module 15, preventing the heat of the charging module 15 from being directly transferred to the surface of the cabinet 1.

[0045] Both the first limiting piece 212 and the second limiting piece 222 abut against the charging module 15, so that the entire heat dissipation airflow passes through the charging module 15, thereby improving the heat dissipation efficiency of the charging module 15.

[0046] The effect of this embodiment:

[0047] Both charging modules 15 are located within the module cavity 13 and within the vertically arranged installation chamber 14. Furthermore, both charging modules 15 are located within the independent air duct formed by the first partition component 21 and the second partition component 22. When the cooling fan 32 of the first side door 11 dissipates heat, the airflow of the cooling fan 32 blows into the independent air duct between the first partition component 21 and the second partition component 22, so that the heat dissipation of the cooling fan 32 can be fully applied to the two charging modules 15 within the independent air duct, thereby improving the heat dissipation efficiency of the charging modules 15.

[0048] Meanwhile, other components inside the cabinet 1 often do not require excessive heat dissipation, thus avoiding unnecessary heat dissipation of other components by the cooling fan 32. This improves the utilization efficiency of the cooling fan 32, enabling the cooling needs of the charging pile to be met with fewer cooling fans 32, and significantly reducing operating noise.

[0049] This specific embodiment is merely an explanation of this application and is not intended to limit it. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of protection claimed in this application.
