Description

Technical Field

[0001] This utility model relates to the field of new energy charging cabinet technology, and in particular to a heat dissipation type new energy charging cabinet. Background Technology

[0002] New energy charging cabinets are devices that provide centralized charging services for new energy vehicles. They are mainly placed in parking lots as charging stations. During the use of the charging cabinet, the components inside the cabinet will generate heat due to operation. In order to extend the service life of the charging cabinet, it is necessary to dissipate heat.

[0003] In related technologies, please refer to Chinese utility model patent with authorization announcement number CN219947931 U, which discloses a charging pile with heat dissipation function, including a charging pile body, a moving mechanism and a heat dissipation mechanism; the moving mechanism includes an internal gear, an external gear, a rotating shaft, a first bevel gear and a second bevel gear, the internal gear is fixedly installed on the top of the charging pile body, the external gear meshes with the internal gear, the external gear is connected to a rotating mechanism that controls its rotation, and the rotating shaft is coaxially fixedly connected to the external gear; the first bevel gear is coaxially fixedly connected to the rotating shaft, the second bevel gear meshes with the first bevel gear, the second bevel gear is vertically arranged and its rotation direction faces the inside of the charging pile, and the heat dissipation mechanism is installed on the second bevel gear through a bracket.

[0004] During use, the moving mechanism controls the heat dissipation mechanism to perform circumferential temperature detection and targeted heat dissipation within the charging pile body. However, the movement of the cooling fan undoubtedly increases the space required inside the charging cabinet, and the movement of the cooling fan may also cause collision damage to other components inside the charging cabinet. Furthermore, when the overall temperature rises, the cooling fan is still moving inside the charging cabinet to dissipate heat, causing the hot air inside the charging cabinet to circulate. The cooling fan designed inside the charging cabinet is not conducive to dissipating the heat inside the charging cabinet to the outside, thus reducing the heat dissipation effect of the charging cabinet. Utility Model Content

[0005] In order to improve the heat dissipation effect and extend the service life of the charging cabinet, this utility model provides a heat dissipation-type new energy charging cabinet.

[0006] The heat-dissipating new energy charging cabinet provided in this application adopts the following technical solution:

[0007] A heat dissipation type new energy charging cabinet includes a cabinet body, on which a charging cable and a charging gun connected to the charging cable are provided. An air inlet grille is provided at the bottom of the cabinet body, and the air inlet holes of the air inlet grille are honeycomb-shaped. A vortex fan is provided at the top of the cabinet body. The vortex fan and the air inlet grille work together to dissipate heat inside the cabinet body. The cabinet body is also provided with a side heat dissipation component.

[0008] By adopting the above technical solution, when the vortex fan is not activated, the honeycomb air intake grille serves as a heat dissipation hole for heat dissipation, and the honeycomb shape improves the heat dissipation effect. When the vortex fan is activated, the honeycomb air intake grille serves as an inlet for external airflow, and the heat inside the cabinet is expelled from the cabinet under the action of the vortex fan. The vortex fan and the air intake grille work together to form airflow convection, thereby improving the heat dissipation effect of the charging cabinet. The side heat dissipation components provide auxiliary heat dissipation, further improving the heat dissipation effect of the charging cabinet and extending its service life.

[0009] Optionally, both side walls of the cabinet have ventilation openings, and two side heat dissipation components are provided, each corresponding to one of the ventilation openings. The side heat dissipation components include:

[0010] Mounting bracket, which is installed at the heat dissipation vent;

[0011] The heat dissipation fin assembly includes multiple heat dissipation fin assemblies, which are vertically spaced on the mounting bracket and extend downward and outward at an angle. Each heat dissipation fin assembly includes two fin units, which are arranged opposite each other and extend outward at an angle.

[0012] The support plate is provided in multiple ways, and the multiple support plates are spaced apart between two adjacent heat dissipation fin groups and are used to support the two adjacent fin units.

[0013] By adopting the above technical solution, the design of the heat dissipation fin assembly increases the heat dissipation area of ​​the charging cabinet when the vortex fan is not running, increases the air intake when the vortex fan is running, promotes air convection on the inclined surface, and reduces the probability of external dust and rainwater entering the cabinet. The support plate increases the rigidity of the fin unit. Even when the vortex fan is not running, heat dissipation can still be achieved through the heat dissipation fin assembly on both sides and the air intake grille at the bottom, thereby improving the heat dissipation effect.

[0014] Optionally, the tilt angle of the heat dissipation fin assembly is 20°-30°.

[0015] Optionally, multiple temperature sensors are vertically spaced within the cabinet. The cabinet has a built-in controller, and the signal output terminals of the multiple temperature sensors are electrically connected to the controller. The output terminal of the controller is connected to the signal input terminal of the vortex fan. When any one of the temperature sensors detects a value exceeding a threshold, the controller controls the vortex fan to start for heat dissipation.

[0016] By adopting the above technical solution, when the temperature inside the cabinet does not exceed the threshold, the cabinet can dissipate heat autonomously through the heat dissipation fins on both sides and the air intake grille at the bottom. When the detected value of any temperature sensor in the cabinet exceeds the threshold, the vortex fan is activated to enhance heat dissipation, thereby improving the heat dissipation effect while reducing energy consumption. If only one sensor is set, it is possible that when the temperature sensor detects a high temperature, some local electrical components far from the temperature sensor may have already overheated and been damaged. The setting of multiple temperature sensors reduces the probability of this happening.

[0017] Optionally, dustproof nets are provided at both the heat dissipation vents and the air intake grille, and the dustproof nets are located inside the cabinet.

[0018] By adopting the above technical solution, the dustproof net blocks the dust mixed in the airflow entering the cabinet, thereby improving the dustproof effect of the cabinet.

[0019] Optionally, the bottom of the cabinet has a counterweight frame with multiple air inlet channels, which are located below the air inlet grille and communicate with the air inlet holes of the air inlet grille.

[0020] By adopting the above technical solutions, the counterweight frame increases the weight of the cabinet, while the air intake channel reduces the impact of the counterweight frame on the air intake volume.

[0021] Optionally, the outer wall of the cabinet has a storage slot for storing charging cables, and the storage slot is provided with a storage component for storing the charging cables.

[0022] By adopting the above technical solution, when not charging, the charging cable can be stored in the storage slot by the storage component, thereby reducing the probability of the charging cable being damaged when hung outside the cabinet and thus improving the service life of the charging cable.

[0023] Optionally, the storage component includes:

[0024] A rotating shaft, which is rotatably disposed within a storage groove and extends horizontally;

[0025] A storage tray is coaxially fixed on a rotating shaft. One end of the charging cable is connected to the battery pack inside the cabinet, and the other end is wound around the storage tray and connected to the charging gun.

[0026] A rotating motor is installed inside the cabinet and its output end is connected to the rotating shaft for transmission.

[0027] By adopting the above technical solution, when in use, the operator pulls the charging gun to detach the charging cable from the storage tray. After use, the rotating motor starts and drives the rotating shaft to rotate, which in turn drives the storage tray to rotate, thereby winding and storing the charging cable. This achieves the storage of the charging cable. The rotating motor is placed inside the cabinet to avoid the probability of the rotating motor being exposed and damaged.

[0028] Optionally, the output end of the rotating motor is connected to the rotating shaft via an electromagnetic clutch, and the outer wall of the cabinet has a start button and a disconnect button. The output ends of the start button and the disconnect button are electrically connected to the input end of the controller, and the output end of the controller is electrically connected to the input end of the electromagnetic clutch.

[0029] By adopting the above technical solution, when charging with the charging gun, first press the disconnect button, the electromagnetic clutch disconnects the connection between the rotating motor and the rotating shaft, and the operator pulls the charging cable to drive the storage tray to rotate, thereby reducing the motor resistance encountered by the operator when pulling the charging cable. After use, press the start button, the electromagnetic clutch reconnects the rotating motor and the rotating shaft, and the rotating motor starts, which can drive the storage tray to rotate and wind up and store the removed charging cable through the rotating shaft, thereby improving the convenience of using the charging cabinet.

[0030] In summary, this application includes at least one of the following beneficial technical effects:

[0031] 1. When the vortex fan is not running, the honeycomb air intake grille acts as a heat dissipation hole, enhancing the heat dissipation effect. When the vortex fan is running, the honeycomb air intake grille acts as an inlet for external airflow. The heat inside the cabinet is expelled by the vortex fan. The vortex fan and the air intake grille work together to create airflow convection, thereby improving the heat dissipation effect of the charging cabinet. Combined with the side heat dissipation components for auxiliary heat dissipation, the heat dissipation effect of the charging cabinet is further improved, extending the service life of the charging cabinet.

[0032] 2. The design of the heat dissipation fin assembly increases the heat dissipation area of ​​the charging cabinet when the vortex fan is not running, and increases the air intake when the vortex fan is running. The inclined surface promotes air convection and reduces the probability of external dust and rainwater entering the cabinet. The support plate increases the rigidity of the fin unit and improves the structural stability.

[0033] 3. The charging cable is stored by rotating the motor and the storage tray. When not charging, the charging cable is stored in the storage slot, reducing the probability of damage to the charging cable when it is hanging outside the cabinet. This improves the lifespan of the charging cable and the convenience of using the charging cabinet. Attached Figure Description

[0040] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0041] This application discloses a heat-dissipating new energy charging cabinet.

[0042] Reference Figure 1 A heat-dissipating new energy charging cabinet includes a cabinet body 1, on which a charging cable 11 and a charging gun 12 connected to the charging cable 11 are provided. A battery pack (not shown in the figure) is built into the cabinet body 1. One end of the charging cable 11 is connected to the power supply end of the battery pack and the other end extends out of the cabinet body 1 and is connected to the charging gun 12. The outer wall of the cabinet body 1 has a placement opening for placing the charging gun 12. The outer wall of the cabinet body 1 has a control panel 13 for easy operation by the operator. The cabinet body 1 has a built-in controller (not shown in the figure). The controller is electrically connected to the control panel 13. For other components that must be included in the new energy charging cabinet, the common configuration in the prior art shall be used as the standard, and this application does not limit them.

[0043] Reference Figure 1 and Figure 2The cabinet 1 has a counterweight frame 14 at its bottom, with multiple air inlet channels 141 distributed around its perimeter. An air inlet grille 2 is fixedly installed at the bottom of the cabinet 1, with honeycomb-shaped air inlets. The air inlet channels 141 are located below the air inlet grille 2 and communicate with its air inlets. Two vortex fans 3 are installed at the top of the cabinet 1 to expel hot air from it. In practical use, existing silent turbine fans can be selected to reduce noise during operation.

[0044] Reference Figure 1 , Figure 2 and Figure 3 The cabinet 1 is also equipped with a side heat dissipation component 4. Both sides of the cabinet 1 have rectangular heat dissipation vents 15. There are two side heat dissipation components 4, which correspond one-to-one with the heat dissipation vents 15. The two side heat dissipation components 4 are arranged opposite each other. The following description only takes one side heat dissipation component 4 as an example.

[0045] Reference Figure 3 and Figure 4 The side heat dissipation component 4 adopts a gill-like design. The side heat dissipation component 4 includes a mounting bracket 41, a heat dissipation fin group 42, and a support plate 43. The mounting bracket 41 is a rectangular frame and is detachably connected to the heat dissipation port 15 by bolts. There are multiple heat dissipation fin groups 42, which are vertically spaced on the mounting bracket 41 and extend outward at an angle. The heat dissipation fin groups 42 are inverted V-shaped, and the tilt angle between the heat dissipation fin groups 42 and the mounting bracket 41 is 20°-30°.

[0046] Reference Figure 3 and Figure 4 Each heat dissipation fin group 42 includes two integrally formed fin units 421. The two fin units 421 are arranged opposite each other and extend outward at an angle. The connection point of the two fin units 421 is the highest point of the inverted V-shaped structure. Multiple support plates 43 are provided. Multiple support plates 43 are spaced apart between two adjacent heat dissipation fin groups 42. The support plates 43 are used to support two adjacent fin units 421 to increase the structural rigidity.

[0047] Reference Figure 2 Two heat dissipation vents 15 and air inlet grille 2 are each provided with a dustproof net 21 on the side facing the inside of the cabinet 1. The dustproof net 21 is located inside the cabinet 1 and is used to filter the airflow entering the cabinet 1. The dustproof net 21 has filter holes evenly distributed on it (not shown in the figure).

[0048] Reference Figure 2Multiple temperature sensors 16 are vertically spaced inside the cabinet 1. The signal output terminals of the multiple temperature sensors 16 are electrically connected to the controller. The output terminal of the controller is electrically connected to the signal input terminals of two vortex fans 3. When the detection value of any one of the temperature sensors 16 exceeds the threshold, the controller controls the vortex fans 3 to start for heat dissipation.

[0049] In this embodiment, the heat dissipation process is as follows: Temperature thresholds are set to 20℃, 40℃, and 60℃. When the temperature inside cabinet 1 is below 20℃, the cabinet 1 self-heats through the heat dissipation fins 42 on both sides and the bottom air intake grille 2. When the temperature at any point inside cabinet 1 is between 20℃ and 40℃, i.e., the detection value of any one temperature sensor 16 exceeds 20℃ while the detection values ​​of the other temperature sensors 16 do not exceed 40℃, the controller controls one of the vortex fans 3 to start. At this time, the bottom air intake grille 2 is converted from a heat dissipation channel to an air intake channel 141, connecting with the top vortex fan. The fans 3 create airflow convection, and the heat inside the cabinet 1 is expelled from the cabinet 1 by the action of the vortex fans 3, thereby improving the heat dissipation effect of the charging cabinet. The heat dissipation fins 42 on both sides provide auxiliary heat dissipation, further improving the heat dissipation effect of the charging cabinet. When the temperature at any point inside the cabinet 1 is above 40℃ and the detection value of the other temperature sensors 16 does not exceed 60℃, the controller controls both vortex fans 3 to start. When the temperature at any point inside the cabinet 1 is above 60℃, the controller alarms to remind the operator so that other cooling measures can be added manually or the power can be cut off, thus improving the service life of the charging cabinet.

[0050] Reference Figure 1 and Figure 3 The outer wall of the cabinet 1 has a storage slot 17 for storing the charging cable 11, and the storage slot 17 is provided with a storage component 5 for storing the charging cable 11.

[0051] Reference Figure 2 , Figure 3 and Figure 5 The storage component 5 includes a rotating shaft 51, a storage tray 52, and a rotating motor 53. The rotating shaft 51 is rotatably disposed in the storage slot 17 and extends horizontally. The storage tray 52 is coaxially fixed on the rotating shaft 51. The end of the charging cable 11 away from the battery pack is wound on the storage tray 52 and connected to the charging gun 12. The rotating motor 53 is disposed in the cabinet 1 and its output end is connected to the rotating shaft 51 through an electromagnetic clutch 54.

[0052] Reference Figure 1 , Figure 3 and Figure 5 The outer wall of the cabinet 1 has a start button 6 and a stop button 7. The outputs of the start button 6 and the stop button 7 are electrically connected to the input of the controller. The output of the controller is electrically connected to the input of the electromagnetic clutch 54.

[0053] When charging with the charging gun 12, first press the disconnect button 7. The electromagnetic clutch 54 disconnects the connection between the rotating motor 53 and the rotating shaft 51. The operator pulls the charging cable 11 to drive the storage tray 52 to rotate, thereby reducing the motor resistance encountered by the operator when pulling the charging cable 11. After use, press the start button 6. The electromagnetic clutch 54 restores the connection between the rotating motor 53 and the rotating shaft 51. At this time, the rotating motor 53 starts and can drive the storage tray 52 to rotate through the rotating shaft 51 to wind and store the removed charging cable 11, thereby improving the convenience of using the charging cabinet.

[0054] The working principle of this application embodiment:

[0055] When the vortex fan 3 is not activated, the honeycomb air intake grille 2 and the heat dissipation fins 42 on both sides work together to achieve self-heating of the cabinet 1. The honeycomb shape improves the heat dissipation effect, and the design of the heat dissipation fins 42 increases the heat dissipation area of ​​the charging cabinet when the vortex fan 3 is not activated. When the vortex fan 3 is activated, the honeycomb air intake grille 2 serves as the inlet for external airflow. The heat inside the cabinet 1 is expelled from the cabinet 1 by the action of the vortex fan 3. The vortex fan 3 and the air intake grille 2 work together to form airflow convection, improving the heat dissipation effect of the charging cabinet. The heat dissipation fins 42 increase the airflow, and the inclined surface promotes air convection, further improving the heat dissipation effect of the charging cabinet and reducing the probability of external dust and rainwater entering the cabinet 1, thus increasing the service life of the charging cabinet.

[0056] The charging cable 11 is stored by rotating the motor 53 and the storage tray 52. ​​When not charging, the charging cable 11 is stored in the storage slot 17, which reduces the probability of the charging cable 11 being damaged when it is hung outside the cabinet 1. This improves the service life of the charging cable 11 and the convenience of using the charging cabinet.

[0057] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
