Charging terminal heat dissipation system and charging terminal

Abstract

This application discloses a charging terminal heat dissipation system and a charging terminal. A temperature sensor monitors the internal temperature in real time, allowing for flexible adjustment of the fan's airflow. This reduces the fan's full-load operation time, lowering energy consumption, and prevents continuous cooling when the intake air temperature is too low, minimizing the impact of low temperatures on the normal operation of the charging module and control circuitry. Simultaneously, the air vent on the first side wall handles air intake, while the cooling fan on the second side wall exhausts hot air from the box. The heat sink and charging module are positioned precisely between them, creating an airflow that quickly removes heat from both, significantly improving heat dissipation efficiency. Furthermore, the front end of the heat sink is in close contact with the charging module, directly and efficiently absorbing its heat. The rear end and the rear side wall of the box have pre-reserved space for heat dissipation, further optimizing the flow of hot air inside the box and effectively preventing damage to the charging module due to high temperatures.

Description

Technical Field

[0001] This application relates to the field of two-wheeled vehicles, and in particular to a charging terminal heat dissipation system and a charging terminal. Background Technology

[0002] Electric two-wheeler charging terminals typically consist of components such as a charging station, a charging housing, a cooling fan, and a charging gun. The housing is mounted on the charging station, the charging gun is connected to the housing and is responsible for charging the electric vehicle's battery, while the cooling fan is housed inside the housing to cool its interior. However, in practical use, it has been found that existing charging stations are not ideal for cooling the core heat-generating components inside the housing, such as the charging module. This makes the charging module prone to damage due to overheating, or it may force a reduction in charging power due to high temperatures. Utility Model Content

[0003] This application aims to provide a heat dissipation system and a charging terminal that can improve the heat dissipation effect of the charging terminal.

[0004] The charging terminal heat dissipation system provided in the first aspect embodiment of this application includes:

[0005] The enclosure has a first sidewall and a second sidewall that are opposite each other in the left-right direction, and the first sidewall is provided with an air vent.

[0006] A cooling fan is installed on the second side wall;

[0007] A mounting bracket is disposed inside the housing. The mounting bracket has a first connecting portion, which is used to install a charging module and to position the charging module between the air vent and the cooling fan.

[0008] A heat sink is provided on the mounting bracket and located between the air vent and the cooling fan. The front end of the heat sink is attached to the charging module, and a heat dissipation space is formed between the rear end of the heat sink and the rear side wall of the housing.

[0009] A temperature detection unit is mounted on the mounting bracket;

[0010] The control unit is electrically connected to the temperature detection unit and the cooling fan, respectively.

[0011] The charging terminal provided in the second aspect of this application includes the charging terminal heat dissipation system described in the first aspect of this application.

[0012] The charging terminal heat dissipation system and charging terminal of this application embodiment can monitor the internal temperature in real time through a temperature sensor, and flexibly adjust the fan airflow accordingly. This reduces the time the fan runs at full load to lower energy consumption, and also prevents continuous cooling when the intake air temperature is too low, reducing the possibility of low temperature affecting the normal operation of the charging module and control circuit. At the same time, the air vent on the first side wall is responsible for air intake, while the cooling fan on the second side wall exhausts the hot air inside the box. The heat sink and the charging module are located precisely between the two, and the resulting airflow can quickly remove heat from both, significantly improving heat dissipation efficiency. Furthermore, the front end of the heat sink is in close contact with the charging module, which can directly and efficiently absorb its heat, while the rear end and the rear side wall of the box have reserved heat dissipation space, further optimizing the flow of hot air inside the box and effectively preventing the charging module from being damaged by high temperature.

[0036] In the description of this application, it should be noted that, unless otherwise explicitly defined, terms such as "setup," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this application in conjunction with the specific content of the technical solution.

[0037] The technical solution of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are some embodiments of this application, not all embodiments.

[0038] The following is for reference. Figures 1 to 9 This application describes a charging terminal heat dissipation system and a charging terminal according to embodiments thereof.

[0039] like Figures 1 to 9 As shown, the charging terminal heat dissipation system of this application embodiment includes:

[0040] The housing 100 has a first sidewall 101 and a second sidewall 102 opposite to each other in the left-right direction, and the first sidewall 101 is provided with an air vent.

[0041] Cooling fan 103 is installed on the second side wall 102;

[0042] Mounting bracket 200 is disposed inside housing 100. Mounting bracket 200 has a first connecting part 201. The first connecting part 201 is used to mount charging module 400 and to position charging module 400 between air vent and cooling fan 103.

[0043] The heat sink 300 is mounted on the mounting bracket 200 and located between the air vent and the cooling fan 103. The front end of the heat sink 300 is attached to the charging module 400, and a heat dissipation space 301 is formed between the rear end of the heat sink 300 and the rear side wall of the housing 100.

[0044] A temperature detection unit is mounted on the mounting bracket 200;

[0045] The control unit 600 is electrically connected to the temperature detection unit and the cooling fan 103, respectively.

[0046] In this embodiment, a temperature sensor can monitor the internal temperature of the enclosure in real time, thereby flexibly adjusting the fan's airflow. This reduces the time the fan operates at full load to lower energy consumption and prevents continuous cooling when the intake air temperature is too low, minimizing the impact of low temperatures on the normal operation of the charging module 400 and the control circuit. Simultaneously, the air vent on the first sidewall 101 is responsible for air intake, while the cooling fan 103 on the second sidewall 102 exhausts hot air from the enclosure. The heat sink 300 and the charging module 400 are positioned precisely between them, and the resulting airflow quickly removes heat from both, significantly improving heat dissipation efficiency. Furthermore, the front end of the heat sink 300 is in close contact with the charging module 400, allowing for direct and efficient heat absorption. The rear end and the rear sidewall of the enclosure 100 have a pre-reserved heat dissipation space 301, further optimizing the flow of hot air inside the enclosure and effectively preventing damage to the charging module 400 due to high temperatures.

[0047] The aforementioned control unit 600 can directly use the core controller of the charging terminal, thereby reducing costs through reuse.

[0048] The aforementioned control unit 600 can be set independently to improve the stability of heat dissipation control.

[0049] The aforementioned control unit 600 can be made using DSP, microcontroller, ARM, etc., and specifically, STM32 series processors can be selected.

[0050] The cooling fan 103 mentioned above can be a fixed-frequency fan or a variable-frequency fan, and the specific choice can be determined according to actual needs.

[0051] When the cooling fan 103 mentioned above is an inverter fan, if the temperature collected by the temperature detection unit is lower than the high temperature threshold, the control unit 600 can control the inverter fan to reduce its speed. In other words, it can be understood that the airflow speed of a fixed-frequency fan is positively correlated with the temperature.

[0052] When the cooling fan 103 is a fixed-frequency fan, if the temperature collected by the temperature detection unit is lower than the low-temperature threshold, the control unit 600 can control the fixed-frequency fan to stop cooling.

[0053] If the temperature collected by the temperature detection unit is lower than the ultra-low temperature threshold, the cooling fan 103 should be stopped to prevent the temperature inside the enclosure 100 from becoming too low.

[0054] The above-mentioned ultra-low temperature threshold is less than the low temperature threshold and less than the high temperature threshold.

[0055] The aforementioned mounting bracket 200 can be connected to the side wall of the housing 100 by fasteners or snapped onto the side wall of the housing 100.

[0056] In some implementations, reference Figure 1 , Figure 8 Temperature detection unit, including:

[0057] The first temperature sensor 710, electrically connected to the control unit 600, is mounted on the mounting bracket 200 and positioned near the cooling fan 103; and / or,

[0058] The second temperature sensor 720 is electrically connected to the control unit 600 and is mounted on the mounting bracket 200 near the air vent.

[0059] In this embodiment, if the first temperature sensor 710 is selected, the temperature at the outlet can be directly detected, and the temperature inside the cabinet 100 can be determined directly based on the outlet temperature, thereby enabling the adjustment of the cooling fan 103.

[0060] In this embodiment, if the first temperature sensor 710 and the second temperature sensor 720 are combined, the outlet temperature and the inlet temperature can be detected simultaneously, thereby determining the temperature difference of the housing 100 and adjusting the operation of the cooling fan 103 more accurately.

[0061] Specifically, based on the detection structure of the first temperature sensor 710, the wind speed can be appropriately reduced when the temperature difference is greater.

[0062] In this embodiment, if the first temperature sensor 710 and the second temperature sensor 720 are used together, the average value of the two can be used as the basis for judgment, and the temperature inside the box 100 can be determined based on the outlet temperature, thereby adjusting the cooling fan 103.

[0063] In some implementations, reference Figure 1 , Figure 4 , Figures 6 to 9 Mounting bracket 200 includes:

[0064] Multiple mounting bases 202 are arranged vertically and extend horizontally, with the rear end of the mounting base 202 connected to the rear side wall of the housing 100.

[0065] Multiple connecting plates 203 are arranged in the left-right direction. Multiple first connecting portions 201 are formed along the length of the connecting plates 203. The multiple first connecting portions 201 of the connecting plates 203 are respectively attached to the front end face of multiple mounting bases 202. The portion of the connecting plate 203 between two adjacent first connecting portions 201 is bent backward to form a mounting groove 204. The heat sink 300 is accommodated in the mounting groove 204.

[0066] The first temperature sensor 710 is disposed on the connection plate 203 near the cooling fan 103, and is located on the back of the connection plate 203, and / or,

[0067] The second temperature sensor 720 is disposed on the connecting plate 203 near the air vent and is located on the back of the connecting plate 203.

[0068] The rear end of the aforementioned mounting base 202 can be connected to the rear side wall of the housing 100 via fasteners.

[0069] The first connecting part 201 can fit against the front end face of the mounting base 202 and be connected to the front end of the mounting base 202 by fasteners.

[0070] The portion of the connecting plate 203 between two adjacent first connecting portions 201 is bent toward the rear side wall of the housing 100 to form a mounting groove 204.

[0071] The multiple mounting slots 204 between the two adjacent mounting bases 202 collectively accommodate the heat sink 300.

[0072] The front end face of the first connecting part 201 is used to install the charging module 400. Specifically, the rear end of the charging module 400 can be attached to the front end face of the first connecting part 201 and connected to the first connecting part 201 by fasteners. After the charging module 400 is installed, the charging module 400 is attached to the front end face of the heat sink 300, so that the heat sink 300 can be clamped and fixed.

[0073] The first temperature sensor 710 and the second temperature sensor 720 are located on the back of the connecting plate 203, which can improve detection accuracy and facilitate wiring.

[0074] The first temperature sensor 710 and the second temperature sensor 720 are respectively positioned close to the part to be detected, which can improve the accuracy of detection.

[0075] In some implementations... Figure 4 , Figures 6 to 9 The connecting plate 203 is bent backward in the portion between two adjacent first connecting portions 201 to form a bent portion 205, the bent portion 205 including:

[0076] Two side plates 206 are respectively attached to the adjacent sides of two mounting bases 202;

[0077] The base plate 207 extends in the vertical direction, and the two ends of the base plate 207 in the length direction are respectively connected to the rear ends of the two side plates 206. The base plate 207 and the two side plates 206 enclose and form the mounting groove 204.

[0078] Among them, the front end face of the bottom plate 207 of the two outermost connecting plates 203 forms a limiting strip 208, which abuts against the left or right end of the radiator 300.

[0079] The first temperature sensor 710 is disposed on the base plate 207 near the cooling fan 103, and is located on the back of the base plate 207, and / or,

[0080] The second temperature sensor 720 is disposed on the base plate 207 near the air vent and is located on the back of the base plate 207.

[0081] In this embodiment, this arrangement makes it more convenient to accommodate the radiator 300, and the side plates 206 respectively abut against the adjacent sides of the two mounting bases 202, which can reduce vibration and swaying of the radiator 300, making the installation of the radiator 300 more stable. Furthermore, when the radiator 300 is placed in the mounting slot 204, the limiting strips 208 on the front end surfaces of the bottom plates 207 of the two outermost connecting plates 203 respectively abut against the left and right ends of the radiator 300, which can prevent the radiator 300 from sliding in the left and right directions, making the installation of the radiator 300 more stable.

[0082] It should be noted that the two outermost connecting plates 203 mentioned in this embodiment refer to the two connecting plates 203 when there are two connecting plates 203, and the two outermost connecting plates 203 in the left-right direction when there are three or more connecting plates 203.

[0083] The first temperature sensor 710 and the second temperature sensor 720 are located on the back of the base plate 207, which can improve detection accuracy and facilitate wiring.

[0084] The first temperature sensor 710 and the second temperature sensor 720 are respectively positioned close to the part to be detected, which can improve the accuracy of detection.

[0085] In some implementations... Figure 4 , Figures 7 to 9 The mounting base 202 has three parts, and the connecting plate 203 has three first connecting parts 201 and two mounting slots 204. The charging module 400 includes an AC charging module 400 and a DC charging module 400. The AC charging module 400 is connected to one set of two adjacent first connecting parts 201 of the connecting plate 203, and the DC charging module 400 is connected to another set of two adjacent first connecting parts 201 of the connecting plate 203. The heat sink 300 has two parts and is installed in the two mounting slots 204 of the connecting plate 203 respectively.

[0086] In this embodiment, the AC charging module 400 can implement AC charging, converting it to DC power via a converter on the electric vehicle before charging. The DC charging module 400 can directly implement DC charging, offering better practicality. Furthermore, both the AC and DC charging modules 400 can be cooled by their respective heat sinks 300, resulting in better heat dissipation.

[0087] In some implementations... Figure 4 , Figures 6 to 9 There are two air vents, corresponding to the AC charging module 400 and the DC charging module 400. There are also two cooling fans 103, corresponding to the AC charging module 400 and the DC charging module 400.

[0088] In this embodiment, two air vents are provided corresponding to the AC charging module 400 and the DC charging module 400 respectively, which can dissipate heat from the AC charging module 400 and the DC charging module 400 respectively, thereby improving heat dissipation efficiency.

[0089] In some implementations... Figure 4 , Figures 6 to 9 There are two first temperature sensors 710, corresponding to the AC charging module 400 and the DC charging module 400, and / or there are two second temperature sensors 720, corresponding to the AC charging module 400 and the DC charging module 400.

[0090] In this embodiment, a first temperature sensor 710 and a second temperature sensor 720 are respectively provided for the AC charging module 400 and the DC charging module 400, which can realize zoned temperature detection, thereby realizing zoned heat dissipation control and reducing power consumption to a certain extent.

[0091] In some implementations... Figure 4 , Figures 6 to 9 At least two ends of the connecting plate 203 are bent forward in the length direction to form support portions 209, and the two support portions 209 of the connecting plate 203 are bent toward each other to form a second connecting portion 210. The mounting bracket 200 also includes:

[0092] Mounting plate 211 is mounted on the front end face of the second connecting part 210 and has a gap between it and the charging module 400. The front end face of mounting plate 211 is used to mount circuit board 500; control unit 600 is disposed on circuit board 500.

[0093] In this embodiment, the two ends of the middle connecting plate 203 in the length direction are bent forward to form support portions 209. The two support portions 209 of the middle connecting plate 203 are bent towards each other to form a second connecting portion 210. The circuit board 500 can be installed on the front end face of the second connecting portion 210. By further setting a mounting plate 211 to assist in the installation of the circuit board 500, the installation can be made more convenient. Moreover, there is a gap between the mounting plate 211 and the charging module 400, which not only avoids the heat of the charging module 400 from being directly transferred to the mounting plate 211, but the mounting plate 211 itself also has a certain heat insulation effect, thus improving the heat insulation effect. In addition, there is a gap between the mounting plate 211 and the charging module 400, thus forming a heat dissipation space 301, which improves the heat dissipation effect.

[0094] In some implementations... Figures 6 to 9 At least part of the mounting base 202 has a channel 212, which is arranged through the left and right directions.

[0095] In this embodiment, some mounting bases 202 may have channels 212, or all mounting bases 202 may have channels 212. The channels 212 can be used for power lines to pass through, making wiring more convenient. In addition, they can also be used for heat dissipation, making them more practical.

[0096] In some implementations, the cooling fan 103 is a variable frequency fan.

[0097] In this embodiment, using a variable frequency fan can better control the airflow from the fan, which can reduce energy consumption to a certain extent.

[0098] In some implementations, reference Figure 1 The aforementioned charging terminal heat dissipation system also includes an alarm module 800 electrically connected to the control unit 600.

[0099] In this embodiment, by adding an alarm module 800, an alarm can be automatically triggered when conditions such as overheating occur, so as to avoid injury to personnel. At the same time, if the alarm module 800 has remote communication transmission capability, it can provide remote early warning, allowing maintenance personnel to proactively troubleshoot the fault as soon as possible and avoid dangers such as open flames.

[0100] The aforementioned alarm module 800 can be an audible and visual alarm to alert local personnel to stay away and avoid casualties.

[0101] The alarm module 800 mentioned above can also be a communication module to provide remote early warning and remind personnel in the central control center to conduct early investigation of potential dangers.

[0102] The alarm module 800 mentioned above can also be a combination of an audible and visual alarm and a communication module.

[0103] In some implementations... Figures 2 to 4 The second side wall 102 is provided with a socket 106, which is located between and adjacent to the two cooling fans 103. The housing 100 is connected to a charging gun, and the socket 106 is used for plugging in the charging gun.

[0104] In this embodiment, two cooling fans 103 are arranged vertically to effectively cool the AC charging module 400 and the DC charging module 400 respectively, resulting in better heat dissipation. Furthermore, the socket 106 is located between and adjacent to the other two cooling fans 103. Thus, when the charging gun plug is not in use and is inserted into the socket 106, the two cooling fans 103 can still cool the plug, preventing damage due to high temperatures. This would prevent unstable connection to the battery charging port, unstable power delivery, or communication failures.

[0105] In some implementations... Figures 2 to 4The radiator 300 includes:

[0106] Heat-conducting plate 302, the thickness direction of heat-conducting plate 302 is parallel to the front-back direction, and the front end face of heat-conducting plate 302 is attached to charging module 400.

[0107] Multiple heat sinks 303 are connected to the rear end face of the heat conduction plate 302 and are arranged at intervals in the vertical direction.

[0108] like Figure 7 As shown, the heat sink 300 includes a heat-conducting plate 302 and multiple heat sinks 303. The thickness direction of the heat-conducting plate 302 is parallel to the front-to-back direction. The front end face of the heat-conducting plate 302 is attached to the charging module 400. The multiple heat sinks 303 are connected to the rear end face of the heat-conducting plate 302 and are arranged at intervals along the vertical direction.

[0109] In this embodiment, the thickness direction of the heat-conducting plate 302 is parallel to the front-back direction, and the front end face of the heat-conducting plate 302 is attached to the charging module 400, resulting in better heat conduction. The heat dissipation effect is further improved by setting multiple heat sinks 303, and the multiple heat sinks 303 are arranged at intervals along the vertical direction, which can further improve the heat dissipation effect.

[0110] In some implementations... Figures 2 to 4 The first sidewall 101 is provided with a filter plate 104 on the outside of the air outlet, and a detachable mesh plate 105 on the inside of the air outlet.

[0111] In this embodiment, a filter plate 104 is provided on the outer side of the air vent, which can filter the air when the air vent is inlet, reducing the entry of dust. A detachable mesh plate 105 is provided on the inner side of the air vent, that is, the mesh plate 105 is located inside the housing 100. The mesh plate 105 does not obstruct the air from entering, but it can play an anti-theft role. Specifically, the mesh plate 105 can only be removed from the inside by opening the door of the housing 100, and cannot be removed directly from the outside. In this way, it can prevent thieves from stealing the components inside the housing 100 through the air vent, and the anti-theft effect is better.

[0112] This application also provides a charging terminal, which includes the above-described charging terminal heat dissipation system.

[0113] It should be noted that since the charging terminal can adopt all the technical solutions of the above-mentioned charging terminal heat dissipation system, it has at least all the beneficial effects brought about by the above-mentioned technical solutions of the charging terminal heat dissipation system. These additional beneficial effects will not be elaborated here.

[0114] It should be clarified that this application is not limited to the specific configurations and processes described above and shown in the figures. For the sake of brevity, detailed descriptions of known methods are omitted here. In the above embodiments, several specific steps are described and shown as examples. However, the method process of this application is not limited to the specific steps described and shown. Those skilled in the art can make various changes, modifications, and additions, or change the order of steps, after understanding the spirit of this application.

[0115] The above are merely specific embodiments of this application. Those skilled in the art will clearly understand that, for the sake of convenience and brevity, the specific working processes of the systems, modules, and units described above can be referred to the corresponding processes in the foregoing method embodiments, and will not be repeated here. It should be understood that the protection scope of this application is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this application, and these modifications or substitutions should all be covered within the protection scope of this application.
