Description

Technical Field

[0001] This application relates to the technical field of charging devices, and particularly to a charging module and a charging system. Background Art

[0002] As the main charging device for new energy vehicles, with the development of charging technology, the power of charging piles is increasing, the external dimensions of charging piles are getting larger, the heat dissipation power is also increasing, and the noise is rising accordingly. However, due to site or other factors, it is difficult to increase without limit as the power of the charging pile increases. It has become a bottleneck for the IP20 air-cooled module to reach a power of 40KW. Therefore, the most feasible solution is to reasonably design the heat dissipation structure of the charging module, reduce the heat dissipation air resistance, and improve the space utilization rate of the charging pile system. In addition, the installation location of the charging pile is getting closer to residential areas, so it is particularly important to reduce the operating noise of the charging pile.

[0003] However, the modules of existing charging piles adopt the ventilation design of communication power modules, with a cooling fan installed on the display panel and input / output terminals installed on the heat dissipation air outlet panel. The system wiring copper bars or wire harnesses block the air outlet duct of the module, resulting in a reduction in the heat dissipation ventilation area and a decrease in the air pressure. To solve this problem, a fan is added at the air outlet position of the module for heat dissipation by suction, and the system wire harnesses and copper bars operate in a high-temperature environment, so large specifications need to be selected.

[0019] In one embodiment, the heat dissipation air outlet panel of each charging module and the module fixing column, the first baffle and the second baffle form a hot air bin, and the first baffle and the second baffle are arranged at the upper edge and the lower edge of the corresponding charging module.

[0025] The present application has the following beneficial effects compared with the prior art:

[0026] In the charging module provided by the present application, the input and output terminal mounting panel is perpendicular to the heat dissipation air inlet panel and the heat dissipation air outlet panel.

[0041] A module display panel 110;

[0042] A heat dissipation air inlet panel 120;

Among them, the indicator lights on the module display panel 110 are not shown in the figure.

[0046] The heat dissipation air intake panel 120 is provided with air intake holes. Through the air intake holes, air flows into the housing 100 to cool the internal electronic components and the like in the housing 100. It can be understood that the shape, size and position of the air intake holes can be set according to actual needs and are not limited herein.

[0047] The heat dissipation air outlet panel 130 is provided with air outlet holes. The hot air in the housing 100 flows out through the air outlet holes to maintain the temperature balance inside the housing 100. It can be understood that the shape, size and position of the air outlet holes can be set according to actual needs and are not limited herein.

[0048] The heat dissipation air intake panel 120 and the heat dissipation air outlet panel 130 are arranged opposite to each other to create an effective air flow path, which can enable natural air convection and improve the heat dissipation efficiency.

[0049] The input / output terminal mounting panel 140 is provided with holes for the wire harness to pass through. The wire harness passes through the holes and can be connected to the incoming terminal and the outgoing terminal of the charging module to realize the connection between the charging module and the power distribution module in the charging system.

[0050] It can be understood that the housing 100 further includes: a first mounting plate 150 and a second mounting plate 160 which are arranged in parallel; the first mounting plate 150 and the second mounting plate 160 are perpendicularly connected to the module display panel 110, the heat dissipation air intake panel 120, the heat dissipation air outlet panel 130, and the input / output terminal mounting panel 140. It can also be understood that one of the first mounting plate 150 and the second mounting plate 160 is the upper cover plate of the housing, and the other is the lower cover plate.

[0051] The module display panel 110, the heat dissipation air intake panel 120, the heat dissipation air outlet panel 130, the input / output terminal mounting panel 140 and the upper and lower cover plates form a hollow housing 100. It can be understood that the housing 100 can be composed of the module display panel 110, the heat dissipation air intake panel 120, the heat dissipation air outlet panel 130, the input / output terminal mounting panel 140, the first mounting plate 150 and the second mounting plate 160, a total of 6 plates are installed; it can also be: the two ends of the first mounting plate 150 are both folded into right angles, and the two ends of the second mounting plate 160 are also both folded into right angles. Air intake holes and air outlet holes are respectively opened in the parts folded down at the two ends of the first mounting plate 150 and the parts folded down at the two ends of the second mounting plate 160 to correspondingly form the heat dissipation air intake panel 120 and the heat dissipation air outlet panel 130. The structure of the housing is not limited herein and can be selected according to the process requirements as long as the functions required by each part can be satisfied.

[0052] The above-mentioned housing 100 internally houses a PFC main board and a DC main board. Among them, the PFC main board is installed on the first mounting plate 150; the DC main board is installed on the second mounting plate 160.

[0053] The PFC main board is mainly responsible for rectifying alternating current into direct current and ensuring the effective transmission of electrical energy through power factor correction technology. The DC main board is responsible for further converting the voltage of the direct current into a voltage that meets the battery charging requirements. It can be understood that the PFC main board and the DC main board are installed in the housing in an up-and-down buckling manner. It can also be understood that they can be installed in the housing with the PFC main board on top and the DC main board below, or with the DC main board on top and the PFC main board below.

[0054] In the charging module provided in this embodiment, the input / output terminal installation panel is vertically arranged with the heat dissipation air inlet panel and the heat dissipation air outlet panel. Compared with the traditional charging module where the heat dissipation air outlet and the input / output terminals are arranged on the same panel, in this embodiment, the heat dissipation air outlet will not have a thermal impact on the wiring harness between the input / output terminals and the power distribution module and the power distribution module, and the power distribution module and the wiring harness, etc. will not affect the heat dissipation channel of the charging module, which is beneficial to reducing the system heat dissipation air resistance and facilitating the heat dissipation of the charging module.

[0055] In one embodiment, the charging module 10 further includes:

[0056] A fan, which is arranged on the heat dissipation air inlet panel 120.

In this embodiment, the fan is arranged at the corresponding position of the air inlet hole, inside the housing 100.

[0058] In this embodiment, arranging a fan on the heat dissipation air inlet panel can actively suck in relatively cold external air and push the hot air inside the housing out, accelerating the transfer and dissipation of heat through forced convection. Compared with passive heat dissipation that relies on natural convection, the forced convection of the fan can more effectively reduce the temperature inside the charging module and keep the electronic components working within a reasonable temperature range.

[0059] Furthermore, the charging module 10 can further include:

[0060] A handle 170, which is arranged on the module display panel 110.

[0061] Specifically, the handle 170 can be detachably arranged on the module display panel 110.

[0062] Arranging the handle 170 on the module display panel 110 can facilitate the charging module to be pulled out or inserted into the charging system.

[0063] Further, first connecting plates 111 and second connecting plates 112 are respectively arranged at both ends where the module display panel 110 is connected to the heat dissipation air inlet panel 120 and the heat dissipation air outlet panel 130.

[0064] Among them, the first connecting plates 111 and the second connecting plates 112 and the module display panel 110 can be integrally designed, or the first connecting plates 111 and the second connecting plates 112 can be respectively fixed to both ends of the module display panel 110 by means such as welding. The specific design method can be selected according to the actual required process and is not limited herein. Figures 1 - 3 Taking the example where the first connecting plates 111 and the second connecting plates 112 and the module display panel 110 are integrally formed. The charging module is installed on the charging system through the first connecting plates 111 and the second connecting plates 112.

[0065] Furthermore, connection holes are provided on both the first connecting plates 111 and the second connecting plates 112.

For example, the charging module is fixedly installed on the charging system by using screws matching the connection holes, etc.

[0066] Referring to Figures 4 - 6 , an embodiment of the present application provides a charging system. The charging system includes a cabinet body, and the cabinet body is divided into a power distribution bin 2 and a charging module bin 1;

[0067] A number of charging modules 10 as provided in the above embodiment are installed in the charging module bin 1;

[0068] The input / output terminal mounting panel 140 of the charging module 10 is arranged on the side close to the power distribution bin 2.

[0069] Specifically, the charging module bin 1 is used to place the charging module. It can be understood that the charging module can be installed on module fixing posts by arranging module fixing posts in the charging module bin 1, or the charging module can be arranged in the charging module bin 1 through a limiting structure. It can also be understood that the charging modules can be installed in parallel in the charging module bin 1, or can be arranged according to actual requirements in the charging module bin 1, and no limitation is made herein.

[0070] The power distribution bin 2 is used to place the power distribution module. It can be understood that a partition can be provided between the power distribution bin 2 and the charging module bin 1 to divide the power distribution bin 2 and the charging module bin 1 into two independent bins, and only holes for wire harnesses to pass through need to be opened on the middle partition. Or no partition can be provided, and only the circuit board of the power distribution module in the power distribution bin 2 is used as a partition between the power distribution bin 2 and the charging module bin 1, and no limitation is made herein.

[0071] The input and output terminal mounting panel of the charging module is arranged on one side close to the power distribution bin, and the power distribution module and the charging module can be directly connected through a wire harness. Compared with the traditional charging module whose outgoing line end is arranged on the air outlet side while the power distribution module cannot be placed on the air outlet side, which results in the need to pull out the wire harness connected to the outgoing line end of the charging module and then connect it to the power distribution module, the wire harness can be shortened, the winding complexity of the wire harness can be reduced, and at the same time, the floor area and volume of the charging system can be reduced.

[0072] In addition, in this embodiment, since the power distribution module will not affect the heat dissipation air duct of the charging module, it is beneficial to reduce the heat dissipation air resistance of the charging system and facilitate the heat dissipation of the charging module.

[0073] In one embodiment, the charging module bin 1 includes a first cabinet door 11, a second cabinet door 12 and a side plate 13;

[0074] The first cabinet door 11 and the side plate 13 are arranged opposite to each other; the first cabinet door 11 corresponds to the heat dissipation air inlet panel 120 of the charging module 10; the side plate 13 corresponds to the heat dissipation air outlet panel 130 of the charging module 10;

[0075] Ventilation openings are provided on both the first cabinet door 11 and the side plate 13;

[0076] The second cabinet door 12 is arranged opposite to the power distribution bin 2; the charging module 10 is pulled out or inserted into the charging module bin 1 from the side of the second cabinet door 12.

[0077] Specifically, the first cabinet door 11 of the charging module bin 1 corresponds to the heat dissipation air inlet panel 120 of the charging module 10, the side plate 13 corresponds to the heat dissipation air outlet panel 130, and the charging module 10 is pulled out or inserted from the side of the second cabinet door 12, and the input and output terminal mounting panel of the charging module 10 is arranged on one side close to the power distribution bin 2, that is, there is no high voltage on the side of the charging module bin 1, which is safe and reliable during maintenance.

[0078] It can be understood that the ventilation opening of the first cabinet door 11 can adopt the form of louvers or several through holes or slits are opened, etc.

[0079] It can also be understood that a dust-proof cotton can be arranged at the ventilation opening of the first cabinet door 11. The designed dust-proof cotton can filter the dust and particulate matter in the external air inhaled when the fan of the charging module rotates, prevent them from entering the interior of the charging module, and reduce the pollution of internal components; in addition, it can also reduce the erosion and accumulation of dust and impurities on the fan blades, maintain the cleanliness of the fan, so as to keep the fan running efficiently and extend its service life.

[0080] Furthermore, a handle can be arranged on the charging module 10 to facilitate the pulling out or insertion of the charging module 10, and the handle is arranged on the module display panel 110 of the charging module 10.

[0081] In one embodiment, the heat dissipation air outlet panel 130 of each charging module 10, the module fixing posts, the first baffle 14 and the second baffle 15 form a hot air chamber, and the first baffle 14 and the second baffle 15 are arranged at the upper edge and the lower edge of the corresponding charging module 10.

[0082] Specifically, the heat dissipation air outlet panel 130 of each charging module 10, the module fixing posts, the first baffle 14 and the second baffle 15 form a hot air chamber. Except for the hot air chamber, other parts in the charging system belong to the cold air chamber, and the hot air chamber and the cold air chamber are isolated. The cold air outside the charging system enters the charging system through the air inlet of the first cabinet door 11. It can be understood that an air inlet fan can be arranged at a reasonable position inside the charging system to form a negative pressure by using the air inlet fan, so as to accelerate the entry of cold air into the charging system. The fan of the charging module 10 blows the hot air inside the charging module 10 into the hot air chamber, and the hot air in the hot air chamber is discharged from the charging system through the ventilation openings on the side plate 13.

[0083] Through the isolation design of the hot air chamber and the cold air chamber, the return of hot air to the cold air area can be avoided, and the temperature inside the charging module can be effectively reduced and the cooling efficiency can be improved.

[0084] In addition, through the above design, the heat dissipation fan installed at the air outlet of the charging module of the traditional charging system can be cancelled or reduced, thereby reducing the system noise and improving the protection level of the system.

[0085] It can be understood that when the gap between adjacent charging modules 10 is small, only the first baffle 14 or the second baffle 15 can be designed. For example, if only the first baffle 14 is designed, the first baffle 14 of the current charging module 10 itself, the corresponding first baffle 14 of the adjacent charging module 10, the heat dissipation air outlet panel and the fixing posts of the current charging module 10 itself form a hot air chamber, and so on. The first baffle 14 of the lowermost charging module 10, the bottom plate of the charging module bin 1, the heat dissipation air outlet panel and the fixing posts of itself form a hot air chamber. This can reduce the use of materials for the baffle, reduce costs, and can also reduce the process and improve work efficiency, etc.

[0086] In one embodiment, the charging module bin 1 further includes a top plate, and a heat dissipation chamber 16 is arranged between the top plate and the top charging module 10, and the heat dissipation chamber 16 is arranged on one side close to the side plate 13.

[0087] Specifically, the hot air chamber designed through the above embodiments can carry out the heat generated by the charging module from the charging system to a great extent. However, there will still be some hot air rising upward. To prevent the rising hot air from causing a high temperature of the charging module above, a heat dissipation chamber 16 can be provided between the charging module at the top and the top plate, which is used to store the excess hot air and discharge it from the ventilation opening. It can be understood that the heat dissipation chamber 16 can be composed of the upper cover plate of the charging module 10 at the top, the top plate of the charging module chamber 1, and the baffle plate provided between them, or can be an independent heat dissipation chamber 16 placed between the top plate of the charging module chamber 1 and the charging module 10 at the top, and is set according to actual requirements, which is not limited herein.

[0088] In one embodiment, the side plate 13 is the third cabinet door. Among them, Figure 5 and Figure 6 the middle side plate 13 is shown by taking the third cabinet door as an example.

[0089] Furthermore, the ventilation openings on the third cabinet door adopt louvers.

[0090] Even further, a fan is provided on the third cabinet door. The fan is not shown in the figure.

[0091] Specifically, setting the side plate 13 as the third cabinet door can facilitate opening the side plate 13 and is convenient for maintaining and managing the air outlet side of the charging system.

[0092] The ventilation openings on the third cabinet door can adopt louvers, or can also adopt the form of a plurality of through holes or a plurality of gaps. Adopting louvers can play a role in waterproofing and is easy to install, disassemble, replace and other operations.

[0093] In addition, setting a fan on the third cabinet door can accelerate the discharge speed of the hot air and improve the heat dissipation efficiency.

[0094] In one embodiment, the first baffle 14 and the second baffle 15 are inclined to match the angle of the louvers.

[0095] Specifically, setting the first baffle 14 and the second baffle 15 to be inclined, the inclination angle can exactly match the inclination angle of the louvers, that is, after the first baffle 14 and the second baffle 15 are inclined, they are clamped with the corresponding gaps of the louvers, which can make the hot air discharge from the charging system more smoothly.

[0096] In the charging system provided by any of the above embodiments, the power distribution chamber includes a fourth cabinet door and a charging gun. It can be understood that the installation positions of the fourth cabinet door and the charging gun can be set according to the requirements of the actual site, which is not limited herein.

[0097] The above are only the specific embodiments of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions within the technical scope disclosed in the present application should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
