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 getting larger, the external dimensions of charging piles are getting larger, the heat dissipation power is also getting larger, and the noise is also increasing. However, due to site or other factors, it is difficult to increase indefinitely with the increase in the power of the charging pile. 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.

[0003] However, the charging module in the existing charging pile adopts the ventilation design of the communication power module. The display panel installs a cooling fan, and the input and output terminals are installed on the heat dissipation outlet panel. The system wiring copper busbar or wire harness blocks 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 harness and copper busbar work in a high-temperature environment, so large specifications need to be selected.

[0039] A heat dissipation air outlet panel 130, which is arranged parallel to and opposite the heat dissipation air inlet panel 120;

[0040] An input / output terminal mounting panel 140, which is perpendicularly connected to both the heat dissipation air inlet panel 120 and the heat dissipation air outlet panel 130; a hole for a wire harness to pass through is formed on the input / output terminal mounting panel 140.

[0041] Specifically, an air inlet hole is formed on the heat dissipation air inlet panel 120, and air flows into the housing through the air inlet hole to cool internal electronic components in the housing, etc. It can be understood that the shape, size, and position of the air inlet hole can all be set according to actual needs and are not limited herein.

[0042] An air outlet hole is formed on the heat dissipation air outlet panel 130, and the hot air in the housing flows out through the air outlet hole to maintain the temperature balance inside the housing. It can be understood that the shape, size, and position of the air outlet hole can all be set according to actual needs and are not limited herein.

[0043] By arranging the heat dissipation air inlet panel 120 and the heat dissipation air outlet panel 130 opposite to each other to create an effective air flow path, natural air convection can be achieved, improving the heat dissipation efficiency.

[0044] The input / output terminal mounting panel 140 is provided with a hole for a wire harness to pass through, and the wire harness passing through the hole can be connected to the incoming line terminal and the outgoing line terminal of the charging module to realize the connection between the charging module and the power distribution module in the charging system.

[0045] In the charging module provided in this embodiment, the input / output terminal mounting panel is perpendicularly connected to both 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 will not have a thermal impact on the wire harness between the input / output terminals and the power distribution module and the power distribution module, and the power distribution module and the wire harness, etc. will not have an impact on 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.

[0046] In one embodiment, the housing further includes:

[0047] The module display panel 110 is disposed parallel to the input / output terminal mounting panel 140.

[0048] The module display panel 110 is perpendicularly connected to both the heat dissipation air inlet panel 120 and the heat dissipation air outlet panel 130.

[0049] Specifically, the module display panel 110 is provided with indicators for displaying the status of the charging module according to actual requirements. For example, a charging status indicator, etc., which facilitates the operator to understand the situation of the charging module. Among them, the indicators on the module display panel 110 are not shown in the figure.

[0050] In one embodiment, the housing further includes:

[0051] A first mounting plate 150 and a second mounting plate 160 which are disposed parallel to each other; the first mounting plate 150 and the second mounting plate 160 are perpendicularly connected to the module display panel 110, the heat dissipation air inlet panel 120, the heat dissipation air outlet panel 130, and the input / output terminal mounting panel 140.

[0052] Specifically, 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.

[0053] The module display panel 110, the heat dissipation air inlet 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.

[0054] It can be understood that the housing can be composed of six plates, namely the module display panel 110, the heat dissipation air inlet 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; or it can also be: the two ends of the first mounting plate 150 are both folded at right angles, and the two ends of the second mounting plate 160 are also both folded at right angles. Air inlet holes and air outlet holes are respectively formed 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 inlet panel 120 and the heat dissipation air outlet panel 130. There is no limitation on how the housing is formed here, and it can be selected according to the process requirements as long as it can meet the functions required by each part.

[0055] In one embodiment, the charging module further includes a PFC main board and a DC main board;

[0056] The PFC main board is mounted on the first mounting plate 150;

[0057] The DC main board is mounted on the second mounting plate 160.

[0058] Specifically, 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, while 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. There is no limitation here. Among them, the PFC main board and the DC main board are not shown in the figure.

[0059] In one embodiment, the charging module further includes:

[0060] A fan, which is arranged on the heat dissipation air inlet panel 120.

[0061] It can be understood that multiple fans can be arranged on the heat dissipation air inlet panel 120 according to actual needs. It can also be understood that the air inlet holes on the heat dissipation air inlet panel 120 can be opened at the corresponding positions of the fans. The fan is not shown in the figure. In this embodiment, the fan is arranged at the corresponding position of the air inlet hole, inside the housing.

[0062] 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.

[0063] In one embodiment, referring to Figure 1 , the charging module further includes:

[0064] A handle 170, which is arranged on the module display panel 110.

[0065] Specifically, the handle 170 can be detachably arranged on the module display panel 110.

[0066] Arranging the handle 170 on the module display panel 110 can facilitate the charging module to be pulled out of or inserted into the charging system.

[0067] In one embodiment, 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.

[0068] Specifically, the first connecting plate 111 and the second connecting plate 112 and the module display panel 110 can be integrally designed, or the first connecting plate 111 and the second connecting plate 112 can be fixed to both ends of the module display panel 110 by welding or other means respectively. The specific design method can be selected according to the actual required process and is not limited herein. Figures 1 - 3 Taking the first connecting plate 111 and the second connecting plate 112 and the module display panel 110 as an integral body as an example in Figures 1 - 3 . The charging module is installed on the charging system through the first connecting plate 111 and the second connecting plate 112.

[0069] In one embodiment, connection holes are provided on both the first connecting plate 111 and the second connecting plate 112.

[0070] Specifically, the charging module can be installed in the charging system through the connection holes provided on the first connecting plate 111 and the second connecting plate 112. For example, screws matching the connection holes are used to fixedly install the charging module on the charging system.

[0071] Referring to Figure 4 , an embodiment of the present application provides a charging system, which includes:

[0072] The charging module provided in the above embodiment;

[0073] A power distribution module, and the input / output terminal mounting panel 140 of the charging module is arranged on one side close to the power distribution module.

[0074] Exemplarily, the charging module can be installed by setting fixing posts in the charging system, or other installation structures can also be adopted, which are not limited herein.

[0075] The input / output terminal mounting panel of the charging module is arranged on one side close to the power distribution module. The power distribution module and the charging module can be directly connected by a wire harness passing through the holes of the input / output terminal mounting panel. Compared with the traditional charging module whose outgoing line end is arranged on the air outlet side, and the power distribution module cannot be placed on the air outlet side, resulting 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, and the winding complexity of the wire harness can be reduced. At the same time, the floor area and volume of the charging system are reduced.

[0076] In addition, in this embodiment, since the power distribution module does 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.

[0077] The above is only the specific implementation manner 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 by 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.
