Description

Technical Field

[0001] This application relates to the field of charging technology, and more particularly to a charging device. Background Technology

[0002] With the rapid development of new energy electric vehicles, the demand for charging equipment is also increasing.

[0003] As the requirements for charging power and efficiency increase, the heat dissipation of charging equipment during the charging process also increases. Liquid-cooled charging equipment is a type of charging equipment that includes a heat dissipation device containing coolant, which is used to dissipate heat from the charging equipment during the charging process.

[0004] In related technologies, heat dissipation devices are difficult to adapt to charging devices of different sizes. Summary of the Invention

[0005] This application provides a charging device in which multiple heat dissipation modules and fluid circulation modules can be configured in different ways to fit different charging device housings, thereby meeting different usage requirements of the charging device and making the configuration of the charging device highly flexible.

[0006] In a first aspect, embodiments of this application provide a charging device, including: a housing, a plurality of heat dissipation modules, and a fluid circulation module, wherein the plurality of heat dissipation modules and the fluid circulation module are disposed within the housing; the plurality of heat dissipation modules and the fluid circulation module can form at least two configurations, and the at least two configurations are different; wherein, the configuration is used to indicate the arrangement of the plurality of heat dissipation modules and the fluid circulation module; when the housing is of one type, the plurality of heat dissipation modules and the fluid circulation module form one of the at least two configurations; when the housing is of another type, the plurality of heat dissipation modules and the fluid circulation module form another of the at least two configurations.

[0007] The charging device provided in this application embodiment comprises a housing, multiple heat dissipation modules, and a fluid circulation module, with the heat dissipation modules and fluid circulation module disposed within the housing. These modules can be flexibly arranged to form at least two different configurations. Thus, when the housing is of one type, the heat dissipation modules and fluid circulation module form one configuration that adapts to that housing; when the housing is of another type, for example, when the size or shape of the housing changes, the heat dissipation modules and fluid circulation module can be rearranged to form another configuration that adapts to another housing. In other words, the heat dissipation modules and fluid circulation module can form different configurations to adapt to charging devices with different housings, thereby meeting different usage requirements of the charging device and making the configuration of the charging device highly flexible.

[0008] In one possible implementation, the charging device provided in this application has the same number of heat dissipation modules in one configuration as it has in another configuration, but the arrangement of the heat dissipation modules in one configuration is different from that in the other. When the charging devices have the same heat dissipation requirements but different housing sizes, by arranging multiple heat dissipation modules and fluid circulation modules, the same number of heat dissipation modules can be configured in different ways to adapt to charging devices with the same heat dissipation requirements but different housings, further increasing the configuration flexibility of the charging device.

[0009] In one possible implementation, the charging device provided in this application includes a heat dissipation module comprising a heat exchanger, an inlet connector, and an outlet connector, both of which are mounted on and connected to the heat exchanger. Multiple heat dissipation modules and a fluid circulation module are connected to form a cooling circuit, which has an inlet and an outlet. The multiple heat dissipation modules are connected in series. The inlet connector of the first heat dissipation module forms an inlet, and the outlet connector of the last heat dissipation module forms an outlet, which is connected to the fluid circulation module. The series connection of multiple heat dissipation modules results in a longer flow path for the coolant, leading to a lower temperature of the coolant after passing through multiple heat dissipation modules, further improving the cooling effect of the charging gun.

[0010] In one possible implementation, the charging device provided in this application further includes a connecting pipe, along the flow direction of the coolant, wherein the outlet connector of the upstream heat dissipation module and the inlet connector of the downstream heat dissipation module are connected via the connecting pipe; the inlet connector and the outlet connector are rotatable relative to the heat exchanger; and / or, the connecting pipe is a flexible hose. This facilitates the formation of different configurations for multiple heat dissipation modules and fluid circulation modules.

[0011] In one possible implementation, the charging device provided in this application includes a fan in each heat dissipation module, and a heat exchanger with opposing air inlet and outlet sides. The fan is located on the air inlet side and connected to the heat exchanger, with each heat exchanger and fan corresponding to the other. This one-to-one correspondence between the fan and heat exchanger allows for individual control of the cooling capacity of each heat dissipation module, resulting in better heat dissipation performance.

[0012] In one possible implementation, the charging device provided in this application includes a heat exchanger comprising a first surface on the air inlet side, a second surface on the air outlet side, and a plurality of side edges connected to the periphery of the first and second surfaces, each side edge having a connecting portion; the charging device also includes a first adapter, through which the connecting portion on one heat exchanger is connected to the connecting portion on another heat exchanger. By providing a connecting portion on each side edge, when changing the configuration from one configuration to another, only a portion of the heat dissipation module needs to be installed or removed, making the adjustment between configurations simpler.

[0013] In one possible implementation, the charging device provided in this application includes a fluid circulation module comprising a liquid storage tank, a pump body, and a control box. The charging device also includes a second adapter, through which the liquid storage tank, pump body, and control box are respectively connected to connection portions on different sides of the same heat exchanger; or, at least two of the liquid storage tank, pump body, and control box are connected to connection portions on the side of the same heat exchanger via the second adapter, and the other is connected to connection portions on the side of another heat exchanger via the second adapter; or, the liquid storage tank, pump body, and control box are respectively connected to connection portions on the sides of different heat exchangers via the second adapter; or, the liquid storage tank, pump body, and control box are connected to the housing via the second adapter. The second adapter facilitates various configurations of the liquid storage tank, pump body, and control box with the heat dissipation module, further increasing the configuration flexibility of the charging device. The liquid storage tank, pump body, and control box can be located in suitable areas without occupying a complete space within the housing, resulting in a more compact layout.

[0014] In one possible implementation, the charging device provided in this application embodiment has multiple heat dissipation modules and fluid circulation modules arranged in an elongated shape along the length of the housing; or, multiple heat dissipation modules and fluid circulation modules arranged in an elongated shape along the height of the housing; or, multiple heat dissipation modules and fluid circulation modules arranged in an L-shaped shape; or, multiple heat dissipation modules and fluid circulation modules arranged in a square shape.

[0015] In one possible implementation, the charging device provided in this application, when multiple heat dissipation modules and fluid circulation modules form a square configuration, has the multiple heat dissipation modules forming an L-shaped configuration with recesses, and the fluid circulation module located at the recesses. This prevents the functional components from increasing the size of the square configuration and avoids the fluid circulation module obstructing the fan's airflow area.

[0016] In one possible implementation, the charging device provided in this application has two adjacent heat dissipation modules that partially overlap in the arrangement direction. This reduces the size of the configuration in the arrangement direction, making it suitable for housings with high heat dissipation requirements but small dimensions in a certain direction.

[0017] In one possible implementation, the charging device provided in this application further includes a charging gun, which includes a cooling pipe. The cooling pipe includes an inlet channel and an outlet channel. The inlet channel is connected to a fluid circulation module, and the outlet channel is connected to an inlet.

[0018] In one possible implementation, the charging device provided in this application embodiment further includes a power supply component located within the housing, at one end of the configuration along an extension direction. The placement of the power supply component within the housing is also quite flexible.

[0019] In one possible implementation, the charging device provided in this application includes a liquid inlet connector or a liquid outlet connector comprising a first connector segment and a second connector segment connected to the first connector segment. The first connector segment and the second connector segment have an included angle. The first connector segment is connected to a heat exchanger and is rotatable relative to the heat exchanger so that the second connector segment can face different directions.

[0020] In one possible implementation, the charging device provided in this application has a heat dissipation module with dimensions of approximately 180mm-250mm along a first direction, approximately 180mm-250mm along a second direction, and approximately 120mm-180mm along a third direction. This allows the heat dissipation module to have both good heat dissipation performance and good assembly flexibility. Attached Figure Description

[0070] The terminology used in the implementation section of this application is only for explaining specific embodiments of this application and is not intended to limit this application. The implementation of the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0071] This application provides a charging device in which multiple heat dissipation modules and fluid circulation modules can be configured in different ways to fit different charging device housings, thereby meeting different usage requirements of the charging device and making the configuration of the charging device highly flexible.

[0072] Figure 1 This is a schematic diagram of the structure of the charging device provided in an embodiment of this application.

[0073] The charging device 1000 may include a charging pile. The charging pile includes a heat dissipation device 100 and a housing 200, with the heat dissipation device 100 located within the housing 200. The charging device 1000 may also include a charging gun 20, which includes a cooling pipe 23. One end of the cooling pipe 23 is connected to the heat dissipation device 100, and the cooling pipe 23 is used to dissipate heat from the charging gun 20.

[0074] Specifically, the charging equipment 1000 can be installed in the outer areas of shopping malls and residential areas, parking lots, charging stations, and other places. The charging equipment 1000 can be used to charge electric vehicles.

[0075] The shell 200 can be a cuboid or a cylindrical structure. Figure 1The housing 200 shown is a cuboid structure, with length L, width W, and height H. The housing 200 includes a bottom wall 210, a top wall 220, and four side walls 230. The charging station also includes a power supply component 300. Both the heat dissipation device 100 and the power supply component 300 can be located within and connected to the housing 200. The housing 200 provides support and protection for the heat dissipation device 100 and the power supply component 300.

[0076] The charging gun 20 includes a gun head 21 and a cable 22. One end of the cable 22 is connected to the power supply component 300, and the other end is connected to the gun head 21.

[0077] In some examples, the charging gun 20 also includes a cooling pipe 23, one end of which is connected to the heat dissipation device 100. The cooling pipe 23 is used to dissipate heat from the cable 22 and the gun head 21. The arrangement of the cooling pipe 23 is only illustrative and is not limited in this embodiment.

[0078] An external power supply device can be electrically connected to the power supply component 300, and the power supply component 300 will transform or rectify the voltage to charge the electric vehicle. Specifically, the cable 22 in the charging gun 20 is used to electrically connect the power supply component 300 and the gun head 21. The gun head 21 is matched with the charging connector in the electric vehicle. When the gun head 21 is plugged into the charging connector of the electric vehicle, the electrical energy in the power supply component 300 can be delivered to the electric vehicle to charge it. The outer side of the housing 200 is also provided with a mounting part. When charging the electric vehicle is not required, the gun head 21 can be mounted on the mounting part of the housing 200.

[0079] Figure 2 A schematic diagram of the structure of the cooling pipe and the charging gun in the charging device is provided for the embodiments of this application.

[0080] See Figure 1 and Figure 2As shown, the cable 22 and the nozzle 21 generate heat during charging, which can be dissipated using coolant. In one possible embodiment, the cooling pipe 23 may include an inlet channel 23a and an outlet channel 23b. The inlet channel 23a and the outlet channel 23b may be wrapped together with the cable 22 by an insulating sleeve 24. The inlet channel 23a and the outlet channel 23b may also extend into the nozzle 21 to dissipate heat from the heat-generating components at the nozzle 21. Both the inlet channel 23a and the outlet channel 23b are connected to the heat dissipation device 100, allowing coolant to flow from the heat dissipation device 100 into the inlet channel 23a to dissipate heat from the cable 22 and the nozzle 21. Coolant carrying significant heat can flow back into the heat dissipation device 100 through the outlet channel 23b, where it is cooled and then flows back into the inlet channel 23a, thus circulating to dissipate heat from the cable 22 and the nozzle 21. It should be noted that the inlet channel 23a and the outlet channel 23b can be... Figure 2 The piping shown can also be two fluid channels separated by a partition. The relative positions of the inlet channel 23a and the outlet channel 23b with the cable 22 can be as follows: Figure 2 As shown, it can also be used with Figure 2 The differences are shown. This application does not limit the arrangement of the cooling pipes in its embodiments.

[0082] See Figures 3 to 12 As shown, the heat dissipation device 100 includes a plurality of heat dissipation modules 110 and a fluid circulation module 120, which are disposed within the housing 200. The plurality of heat dissipation modules 110 and fluid circulation modules 120 can form at least two different configurations. The configuration is used to indicate the arrangement of the plurality of heat dissipation modules 110 and fluid circulation modules 120. When the housing 200 is one type of housing, the plurality of heat dissipation modules 110 and fluid circulation modules 120 form one of the at least two configurations. When the housing 200 is another type of housing, the plurality of heat dissipation modules 110 and fluid circulation modules 120 form the other of the at least two configurations.

[0083] The size of the housing 200 of the charging device 1000 varies depending on the installation environment. For example, the housing 200 is larger in shopping malls and charging stations, and smaller in the outer areas of residential areas and parking lots. Furthermore, different manufacturers have different designs for their charging devices. This application embodiment provides a solution to meet the unique design requirements of charging devices from different manufacturers. The charging device 1000 provided in this application embodiment offers high configuration flexibility and can be adapted to various usage needs.

[0084] For example, in some housings 200, the space reserved for the heat dissipation device 100 along the length direction L of the housing 200 is relatively large, while the space reserved for the heat dissipation device 100 along the height direction H of the housing 200 is relatively small. In this case, the housing 200 is the first housing. Please continue to see... Figure 3 As shown, the two heat dissipation modules 110 are a first heat dissipation module 110a and a second heat dissipation module 110b, respectively. The first heat dissipation module 110a and the second heat dissipation module 110b are arranged along the length direction L, and together they form a fluid circulation module 120. Figure 3 The configuration shown, Figure 3 The configuration shown is called the first configuration, which is adapted to the internal space of the first shell.

[0085] For example, if the space reserved for the heat dissipation device 100 along the length L of the housing 200 is further increased, then the housing 200 is referred to as the second housing. Please continue to see... Figure 5 As shown, relative to Figure 3In this case, the heat dissipation module 110 can be increased to three, namely a first heat dissipation module 110a, a second heat dissipation module 110b, and a third heat dissipation module 110c. The first heat dissipation module 110a, the second heat dissipation module 110b, and the third heat dissipation module 110c are arranged along the length direction L, and the first heat dissipation module 110a, the second heat dissipation module 110b, the third heat dissipation module 110c and the fluid circulation module 120 form a Figure 5 The configuration shown, Figure 5 The configuration shown is called the second configuration, which is adapted to the second shell.

[0086] For example, in some housings 200, the space reserved for the heat dissipation device 100 along the length direction L of the housing 200 is relatively small, while the space reserved for the heat dissipation device 100 along the height direction H of the housing 200 is relatively large. In this case, the housing 200 is a third housing. Please continue to see... Figure 6 As shown, the two heat dissipation modules 110 are a first heat dissipation module 110a and a second heat dissipation module 110b, respectively. The first heat dissipation module 110a and the second heat dissipation module 110b are arranged along the height direction H, and together they form a fluid circulation module 120. Figure 6 The configuration shown, Figure 6 The configuration shown is called the third configuration, which is adapted to the internal space of the third shell.

[0087] For example, if the space reserved for the heat dissipation device 100 along the height direction H of the housing 200 is further increased, then the housing 200 is referred to as a fourth housing. Please continue to see... Figure 7 As shown, relative to Figure 6 In this context, there can be three heat dissipation modules 110, namely a first heat dissipation module 110a, a second heat dissipation module 110b, and a third heat dissipation module 110c. The first heat dissipation module 110a, the second heat dissipation module 110b, and the third heat dissipation module 110c are arranged along the height direction H, and together with the fluid circulation module 120, they form a [combination / structure]. Figure 7 The configuration shown, Figure 7 The configuration shown is called the fourth configuration, which is adapted to the fourth shell.

[0088] For example, in some housings 200, the space reserved for the heat dissipation device 100 along the length direction L of the housing 200 is close to the space reserved for the heat dissipation device 100 along the height direction H of the housing 200. In this case, the housing 200 is a fifth housing. Please continue to see... Figure 8As shown, there can be three heat dissipation modules 110, namely a first heat dissipation module 110a, a second heat dissipation module 110b, and a third heat dissipation module 110c. The second heat dissipation module 110b is located to one side of the first heat dissipation module 110a along the length direction L, and the third heat dissipation module 110c is located above the first heat dissipation module 110a along the height direction H. The first heat dissipation module 110a, the second heat dissipation module 110b, the third heat dissipation module 110c, and the fluid circulation module 120 form a heat dissipation module 110a. Figure 8 The configuration shown, Figure 8 The configuration shown is called the fifth configuration, which is adapted to the fifth shell.

[0089] For example, in some housings 200, the space reserved for the heat dissipation device 100 along the length direction L of the housing 200 is close to the space reserved for the heat dissipation device 100 along the height direction H of the housing 200. In this case, the housing 200 is the sixth housing. Please continue to see... Figure 10 As shown, there can be four heat dissipation modules 110. Three of these modules are designated as a first heat dissipation module 110a, a second heat dissipation module 110b, a third heat dissipation module 110c, and a fourth heat dissipation module 110d. These modules, along with the fluid circulation module 120, form a complete system. Figure 9 The configuration shown, Figure 9 The configuration shown is called the sixth configuration, which is adapted to the sixth shell.

[0090] Similarly, the configurations in the other attached figures will not be described in detail.

[0091] The charging device 1000 provided in this application embodiment includes a housing 200, multiple heat dissipation modules 110, and a fluid circulation module 120. The multiple heat dissipation modules 110 and the fluid circulation module 120 are disposed within the housing 200. The multiple heat dissipation modules 110 and the fluid circulation module 120 can be flexibly arranged to form at least two different configurations. Therefore, when the housing 200 is of one type, the multiple heat dissipation modules 110 and the fluid circulation module 120 form a configuration that can be adapted to this housing 200. When the housing 200 is changed from one type to another, for example, when the size of the housing 200 changes, the multiple heat dissipation modules 110 and the fluid circulation module 120 can be rearranged to form another configuration that can be adapted to another housing 200. In other words, the multiple heat dissipation modules 110 and the fluid circulation module 120 can form different configurations to adapt to charging devices 1000 with different housings 200, thereby meeting the different usage requirements of the charging devices 1000 and making the configuration of the charging devices 1000 highly flexible.

[0092] In one possible implementation, the number of heat dissipation modules 110 forming one configuration is the same as the number of heat dissipation modules 110 forming another configuration, and the arrangement of heat dissipation modules 110 in one configuration is different from the arrangement of heat dissipation modules 110 in another configuration.

[0093] Understandably, the configuration is determined by the number and arrangement of the heat dissipation modules 110. For example, Figure 3 , Figure 4 and Figure 6 The number of heat dissipation modules 110 is two in each case. Figure 3 The configuration formed by the heat dissipation module 110 and the fluid circulation module 120 Figure 4 The configuration formed by the heat dissipation module 110 and the fluid circulation module 120, and Figure 6 The configurations of the heat dissipation module 110 and the fluid circulation module 120 are all different.

[0094] For example, Figure 5 , Figure 7 , Figure 8 and Figure 9 The number of heat dissipation modules 110 in each module is three. Figure 5 The configuration formed by the heat dissipation module 110 and the fluid circulation module 120 Figure 7 The configuration formed by the heat dissipation module 110 and the fluid circulation module 120 Figure 8 The configuration formed by the heat dissipation module 110 and the fluid circulation module 120, and Figure 9 The configurations of the heat dissipation module 110 and the fluid circulation module 120 are all different.

[0095] For example, Figure 10 , Figure 11 and Figure 12 The number of heat dissipation modules 110 in each module is four. Figure 10 The configuration formed by the heat dissipation module 110 and the fluid circulation module 120 Figure 11 The configuration formed by the heat dissipation module 110 and the fluid circulation module 120, and Figure 12 The configurations of the heat dissipation module 110 and the fluid circulation module 120 are all different.

[0096] In other words, the same number of heat dissipation modules 110 can form multiple configurations, and the heat dissipation capacity of the same number of heat dissipation modules 110 is the same. That is to say, when the charging devices 1000 have the same heat dissipation requirements but the size of the housing 200 of the charging devices 1000 is different, by arranging multiple heat dissipation modules 110 and fluid circulation modules 120, the same number of heat dissipation modules 110 can also form different configurations to adapt to charging devices 1000 with the same heat dissipation requirements but different housings 200, further increasing the configuration flexibility of the charging devices 1000.

[0097] It should be noted that different numbers of heat dissipation modules 110 can also form the same configuration, for example, in Figure 9 In the middle, the three heat dissipation modules 110 and the fluid circulation module 120 can form a square configuration. Figure 10 In the middle, the four heat dissipation modules 110 and the fluid circulation module 120 can also form a square configuration.

[0098] The specific structure of the heat dissipation module 110 will be described below.

[0099] Figure 13 A schematic diagram of the heat dissipation module in the charging device provided in this application embodiment. Figure 1 ; Figure 14 for Figure 13 An explosion diagram.

[0100] See Figure 13 and Figure 14 As shown, the heat dissipation module 110 includes a heat exchanger 111, a liquid inlet connector 112, and a liquid outlet connector 113, both of which are connected to the heat exchanger 111.

[0101] Please continue reading Figure 13 and Figure 14As shown, the heat dissipation module 110 also includes a support structure 114. The support structure 114 can be a cuboid structure, and it has a first direction X, a second direction Y, and a third direction Z. Depending on the orientation of the heat dissipation module 110 in the housing 200, the first direction X, the second direction Y, and the third direction Z can be the same as the length direction L, the width direction W, and the height direction H, respectively, or they can be different from the length direction L, the width direction W, and the height direction H. The support structure 114 includes a base plate 1141 and four side plates 1142 surrounding the base plate. The four side plates 1142 are a first side plate 1142a, a second side plate 1142b, a third side plate 1142c, and a fourth side plate 1142d connected in sequence. The first side plate 1142a and the third side plate 1142c are arranged opposite each other along the first direction X, and the second side plate 1142b and the fourth side plate 1142d are arranged opposite each other along the second direction Y. The bottom plate 1141 and the side plate 1142 form a receiving cavity, and the heat exchanger 111 is located in the receiving cavity and connected to the bottom plate 1141 or the side plate 1142.

[0102] The heat exchanger 111 may include a first heat exchange element 1111, a second heat exchange element 1112, and a plurality of third heat exchange elements 1113. The first heat exchange element 1111 may be located on one side of the second side plate 1142b and connected to the second side plate 1142b. The second heat exchange element 1112 may be located on one side of the fourth side plate 1142d and connected to the fourth side plate 1142d. The plurality of third heat exchange elements 1113 are located between the first heat exchange element 1111 and the second heat exchange element 1112.

[0103] Please see Figure 13 and Figure 14 As shown, in one possible implementation, the liquid inlet connector 112 is connected to the first heat exchanger 1111, and the liquid outlet connector 113 is connected to the second heat exchanger 1112.

[0104] Figure 15 for Figure 13 A schematic diagram showing the flow of coolant.

[0105] See Figure 15 As shown, the first heat exchanger 1111 includes a first channel 1111a, the second heat exchanger 1112 includes a second channel 1112a, and the third heat exchanger 1113 includes a third channel 1113a. The liquid inlet connector 112, the first channel 1111a, the third channel 1113a, the second channel 1112a, and the liquid outlet connector 113 are connected in sequence.

[0106] Please continue reading Figure 13 and Figure 14As shown, the heat dissipation module 110 also includes a fan 115, which is mounted on a base plate 1141. The base plate 1141 has an air duct with a size similar to that of the fan 115, through which the airflow of the fan 115 can pass. The base plate 1141 is the air intake side, and the side opposite to the base plate 1141 along the third direction Z is the air outlet side. The air intake side and the air outlet side are respectively formed with a first surface and a second surface. The airflow of the fan 115 blows from the air intake side to the air outlet side, that is, the direction of the airflow is from the first surface to the second surface. Figure 13 and Figure 14 In the illustrated embodiment, four side plates 1142 form the four sides of the heat exchanger 111, and the four sides are connected to the periphery of the first and second surfaces. In this embodiment, the fan 115 is arranged in a one-to-one correspondence with the heat exchanger 111, and the projected area of ​​the fan 115 along the third direction Z can be close to the projected area of ​​the base plate 1141 of the support structure 114 along the third direction Z. Therefore, the fan 115 can effectively cool the coolant in the heat exchanger 111. The one-to-one correspondence between the fan 115 and the heat exchanger 111 also allows the cooling capacity of each heat dissipation module 110 to be controlled individually, resulting in better heat dissipation effect for the heat dissipation module 110.

[0107] The coolant, which has absorbed heat from the charging gun 20, enters the heat exchanger 111 through the inlet connector 112 and flows sequentially through the first channel 1111a, the third channel 1113a, and the second channel 1112a. As the coolant flows through the first channel 1111a, the third channel 1113a, and the second channel 1112a, the airflow from the fan 115 carries away the heat from the coolant, allowing the coolant at a lower temperature to flow out through the outlet connector 113.

[0108] Figure 16 Schematic diagram of the structure of the heat dissipation module in the heat dissipation device provided in the embodiments of this application. Figure 1 ; Figure 17 for Figure 16 A schematic diagram showing the flow of coolant.

[0109] See Figure 16 and Figure 17 As shown, in one possible implementation, both the inlet connector 112 and the outlet connector 113 are connected to the first heat exchanger 1111. The first channel 1111a includes a first inlet section 1111b and a first outlet section 1111c, which are separated by a partition 1111d. A portion of the third heat exchanger 1113 has its two ends of the third channel 1113a connected to the first inlet section 1111b and the second channel 1112a, respectively. Another portion of the third heat exchanger 1113 has its two ends of the third channel 1113a connected to the first outlet section 1111c and the second channel 1112a, respectively.

[0110] The coolant, having absorbed heat from the charging gun 20, enters the heat exchanger 111 through the inlet connector 112. It flows sequentially through the first inlet section 1111b, a portion of the third heat exchanger 1113 containing the third channel 1113a, the second channel 1112a, another portion of the third heat exchanger 1113 containing the third channel 1113a, and the first outlet section 1111c. As the coolant flows through the first inlet section 1111b, the third channel 1113a, the second channel 1112a, another portion of the third heat exchanger 1113 containing the third channel 1113a, and the first outlet section 1111c, the airflow from the fan 115 carries away the heat from the coolant, allowing the coolant at a lower temperature to flow out from the outlet connector 113.

[0111] It should be noted that the structure of heat exchanger 111 can also be the same as... Figure 13 and Figure 16 The differences are shown. This application does not limit the specific structure of the heat exchanger 111 in its embodiments.

[0112] Figure 18 A schematic diagram of the flow path of the coolant in the heat dissipation device provided in the embodiments of this application; Figure 19 This is a schematic diagram of another flow path of the coolant in the heat dissipation device provided in the embodiments of this application.

[0113] See Figure 18 and Figure 19 As shown, multiple heat dissipation modules 110 and fluid circulation modules 120 are connected to form a cooling circuit, and the cooling circuit has a liquid inlet 140 and a liquid outlet 150; multiple heat dissipation modules 110 are connected in series; the liquid inlet connector 112 of the heat dissipation module 110 at the first end forms the liquid inlet 140, and the liquid outlet connector 113 of the heat dissipation module 110 at the end forms the liquid outlet, and the liquid outlet is connected to the fluid circulation module 120.

[0114] The heat dissipation device 100 includes two heat dissipation modules 110. The two heat dissipation modules 110 are a first heat dissipation module 110a and a second heat dissipation module 110b. The liquid outlet connector 113 of the first heat dissipation module 110a and the liquid inlet connector 112 of the second heat dissipation module 110b are connected, so that the first heat dissipation module 110a and the second heat dissipation module 110b are connected in series. The first heat dissipation module 110a, the second heat dissipation module 110b, and the fluid circulation module 120 are connected to form a cooling circuit.

[0115] The liquid inlet connector 112 of the first heat dissipation module 110a forms the liquid inlet 140 of the cooling circuit, and the liquid outlet connector 113 of the second heat dissipation module 110b forms the liquid outlet 150 of the cooling circuit.

[0116] The inlet 140 is connected to the outlet channel 23b of the cooling pipe 23, and the outlet 150 is connected to the inlet channel 23a of the cooling pipe 23. The coolant, having absorbed heat from the charging gun 20, enters the first heat dissipation module 110a through the outlet channel 23b and the inlet 140. It then flows sequentially through the first heat dissipation module 110a and the second heat dissipation module 110b. After cooling down in multiple heat dissipation modules 110, the coolant, at a lower temperature, re-enters the inlet channel 23a through the outlet 150, thus circulating to dissipate heat from the charging gun 20. The series connection of multiple heat dissipation modules 110a extends the coolant flow path, resulting in a lower temperature after passing through multiple heat dissipation modules 110a, further improving the cooling effect on the charging gun 20.

[0117] Please continue reading Figure 3 As shown, along the flow direction of the coolant, the outlet connector 113 of the upstream heat dissipation module 110 and the inlet connector 112 of the downstream heat dissipation module 110 are connected by a connecting pipe 160; the inlet connector 112 and the outlet connector 113 can rotate relative to the heat exchanger.

[0118] Please continue reading Figure 13 As shown, the inlet connector 112 or outlet connector 113 includes a first connector section 1121 and a second connector section 1122 connected to the first connector section 1121. The first connector section 1121 and the second connector section 1122 have an included angle. The first connector section 1121 is connected to the heat exchanger 111 and can rotate relative to the heat exchanger 111 so that the second connector section 1122 can be oriented in different directions.

[0119] When the heat dissipation modules 110 are arranged in different directions, the liquid outlet connector 113 of the upstream heat dissipation module 110 can be turned to face the liquid inlet connector 112 of the downstream heat dissipation module 110, so that the connecting pipe 160 can easily connect the two heat dissipation modules 110, and facilitate the formation of different configurations of multiple heat dissipation modules 110 and fluid circulation module 120.

[0120] Since both the inlet connector 112 and the outlet connector 113 can rotate relative to the heat exchanger 111, communication between the multiple heat dissipation modules 110 is convenient regardless of their configuration, further increasing the configuration flexibility of the charging device 1000. It should be noted that in other configurations, the outlet connector 113 of the upstream heat dissipation module 110 is connected to the inlet connector 112 of the downstream heat dissipation module 110 via a connecting pipe 160, which is not shown in the figure.

[0121] In one possible implementation, the connecting pipe 160 is a flexible hose. When the connecting pipe 160 connects the outlet connector 113 of the upstream heat dissipation module 110 to the inlet connector 112 of the downstream heat dissipation module 110, the connecting pipe 160 can be bent according to the orientation of the inlet connector 112 and the outlet connector 113, which can also facilitate the connection between multiple heat dissipation modules 110.

[0122] It should be noted that in some configurations, the inlet connector 112 and the outlet connector 113 can be rotated relative to the heat exchanger, and the connecting pipe 160 is a flexible hose, which further increases the configuration flexibility of the charging device 1000.

[0123] The specific connection methods of the multiple heat dissipation modules 110 are explained below.

[0124] In one possible implementation, each side plate 1142 has a connecting portion 116; the charging device 1000 also includes a first adapter 400, through which the connecting portion 116 on one heat exchanger 111 is connected to the connecting portion 116 on another heat exchanger 111.

[0125] Please continue reading Figure 13 and Figure 14 As shown, connecting portions 116 are provided on the first side plate 1142a, the second side plate 1142b, the third side plate 1142c, and the fourth side plate 1142d. Figure 13 and Figure 14 In the illustrated embodiment, the connecting portion 116 is schematically shown as a mounting hole, through which a fastener can connect the first adapter 400 and the connecting portion 116. The connecting portion 116 is provided on each side plate 1142, facilitating connection between the multiple heat dissipation modules 110 and the fluid circulation module 120 when they form different configurations, and also facilitating changes in configuration from one to another.

[0126] For example, in Figure 4 In the configuration shown, the connecting portion 116 of the second side plate 1142b of the first heat dissipation module 110a can be connected to the connecting portion 116 on the second side plate 1142b of the second heat dissipation module 110b via the first adapter 400. The connecting portion 116 of the fourth side plate 1142d of the first heat dissipation module 110a can also be connected to the connecting portion 116 on the fourth side plate 1142d of the second heat dissipation module 110b via the first adapter 400. When it is necessary to... Figure 4 The configuration shown transforms into Figure 5In the configuration shown, the connection method of the first heat dissipation module 110a and the second heat dissipation module 110b remains unchanged. The third heat dissipation module 110c is placed on the side of the second heat dissipation module 110b away from the first heat dissipation module 110a. The second side plate 1142b of the second heat dissipation module 110b and the second side plate 1142b of the third heat dissipation module 110c are connected by the first adapter 400. The fourth side plate 1142d of the second heat dissipation module 110b and the fourth side plate 1142d of the third heat dissipation module 110c are connected by the first adapter 400.

[0127] In other words, by providing a connecting part 116 on each side plate 1142, when changing the configuration from one configuration to another, only a part of the heat dissipation module 110 needs to be installed or removed, making the adjustment between configurations simpler.

[0128] The specific structure of the fluid circulation module 120 and the specific connection method between the fluid circulation module 120 and the heat dissipation module 110 will be described below.

[0129] The fluid circulation module 120 includes a reservoir 121, a pump body 122, and a control box 123. The reservoir 121 stores coolant. The pump body 122 provides power for coolant circulation. The outlet 150 of the cooling circuit and the reservoir 121 can be connected by a hose, and the reservoir 121 and the pump body 122 can be connected by a hose. The pump body 122 is connected to the inlet channel 23a of the cooling pipe 23 via a hose. After the coolant flowing out of the outlet 150 of the cooling circuit is stored in the reservoir 121, it is accelerated by the pump body 122 and flows into the inlet channel 23a of the cooling pipe 23. A fluid connector 125 can also be provided between the pump body 122 and the coolant inlet channel 23a.

[0130] The control box 123 is equipped with a controller that can be used to detect the flow rate of the coolant. The charging device 1000 also includes a second adapter 124, which allows for multiple connection methods between the coolant tank 121, the pump body 122, and the control box 123.

[0131] In one possible implementation, the liquid storage tank 121, pump body 122, and control box 123 are respectively connected to the connection portions 116 on different sides of the same heat exchanger 111 via a second adapter 124. For example, in Figure 3In this configuration, the liquid storage tank 121 is connected to the third side plate 1142c of the first heat dissipation module 110a via the second adapter 124 (the connection is partially obscured by the second heat dissipation module 110b). The control box 123 is connected to the first side plate 1142a of the first heat dissipation module 110a via the second adapter 124. The pump body 122 is connected to the second side plate 1142b of the first heat dissipation module 110a via the second adapter 124. The liquid storage tank 121, pump body 122, and control box 123 are respectively connected to the connection portions 116 of different side plates 1142 of the same heat exchanger 111 via the second adapter 124, which allows for the efficient use of the four sides of the heat exchanger 111. Furthermore, when the configuration needs to be changed from one configuration to another, the connection of the heat dissipation module 110 of the liquid storage tank 121, pump body 122 and control box 123 can remain unchanged. Only other heat dissipation modules 110 need to be replaced, which makes it easy to change the configuration from one configuration to another.

[0132] In another possible implementation, at least two of the liquid storage tank 121, pump body 122, and control box 123 are connected to the side connection portion 116 of the same heat exchanger 111 via a second adapter 124, and the other is connected to the side connection portion 116 of another heat exchanger 111 via a second adapter 124. For example, in Figure 4 and Figure 6 In this configuration, the control box 123 is connected to the side plate 1142 of the first heat dissipation module 110, and the liquid storage tank 121 and the pump body 122 are connected to the side plate 1142 of the second heat dissipation module 110. Figure 7 In this configuration, the liquid storage tank 121 and the control box 123 are connected to the side plate 1142 of the first heat dissipation module 110, and the pump body 122 is connected to the side plate 1142 of the third heat dissipation module 110c. This reduces the amount of airflow area obstructed by the liquid storage tank 121, pump body 122, and control box 123 within the same heat dissipation module 110, and also avoids excessive load on a single heat dissipation module 110.

[0133] In another possible implementation, the liquid storage tank 121, the pump body 122, and the control box 123 are respectively connected to the side connection portions 116 of different heat exchangers 111 via the second adapter 124. Figure 5 , Figure 10 , Figure 11 and Figure 12 Therefore, it can reduce the amount of airflow area of ​​the fan 115 in the same heat dissipation module 110 that is excessively blocked by the liquid storage tank 121, pump body 122 and control box 123, and also avoid the excessive load on a heat dissipation module 110.

[0134] In another possible implementation, the liquid storage tank 121, pump body 122, and control box 123 are connected to the housing 200 via a second adapter 124. This allows for full utilization of the space within the housing 200.

[0135] The second adapter 124 allows the liquid storage tank 121, pump body 122 and control box 123 to form various different configurations with the heat dissipation module 110, further increasing the configuration flexibility of the charging device 1000.

[0136] Below, some configurations are illustrated with examples.

[0137] See Figures 3 to 5 As shown, multiple heat dissipation modules 110 and fluid circulation modules 120 are arranged in an elongated strip configuration along the length L of the housing 200. See also Figure 6 and Figure 7 As shown, multiple heat dissipation modules 110 and fluid circulation modules 120 form an elongated strip configuration arranged along the height direction H of the housing 200. See also Figure 8 As shown, multiple heat dissipation modules 110 and fluid circulation modules 120 form an L-shaped configuration. See also... Figures 9 to 12 As shown, multiple heat dissipation modules 110 and fluid circulation modules 120 form a square configuration. In addition to the configurations listed above, the multiple heat dissipation modules 110 and fluid circulation modules 120 can also form other configurations.

[0138] Please continue reading Figure 9 As shown, in one possible implementation, when the multiple heat dissipation modules 110 and the fluid circulation module 120 form a square configuration, the multiple heat dissipation modules 110 form an L-shaped configuration with a recess 130, and the fluid circulation module 120 is located at the recess 130. The liquid storage tank 121 and the pump body 122 are connected to the third heat dissipation module 110c via a second adapter 124, and the control box 123 is connected to the first heat dissipation module 110a via the second adapter 124. This ensures that the fluid circulation module 120 does not increase the size of the square configuration and avoids the fluid circulation module 120 obstructing the airflow area of ​​the fan 115.

[0139] In one possible implementation, two adjacent heat dissipation modules 110 partially overlap in the arrangement direction. For example, in Figure 11 In the first heat dissipation module 110a and the second heat dissipation module 110b, which are adjacent along the length direction L, partially overlap along the length direction L, and the third heat dissipation module 110c and the fourth heat dissipation module 110d, which are adjacent along the length direction L, also partially overlap along the length direction L. For example, in Figure 12 In the configuration, the first heat dissipation module 110a and the third heat dissipation module 110c, which are adjacent along the height direction H, partially overlap, as do the second heat dissipation module 110b and the fourth heat dissipation module 110d, which are adjacent along the height direction H. This reduces the size of the configuration in the arrangement direction, making it suitable for housings 200 that have high heat dissipation requirements but small dimensions in a certain direction.

[0140] Additionally, it should be noted that the power supply component 300 is located at one end of the configuration along one extension direction. The power supply component 300 can be located at one end of the configuration along the length direction L, the width direction W, or the height direction H within the housing 200. The specific location can be determined according to the dimensions within the housing 200, and the placement of the power supply component 300 within the housing 200 is quite flexible.

[0141] When the volume of the heat dissipation module 110 is too large, the flexibility of splicing multiple heat dissipation modules 110 is small. When the volume of the heat dissipation module 110 is too small, the flow path of the coolant in the heat dissipation module 110 is short, and the cooling effect of the heat dissipation module 110 on the coolant is poor.

[0142] Therefore, in one possible implementation, the dimension of the heat dissipation module 110 along the first direction X can be 180mm-250mm, the dimension of the heat dissipation module 110 along the second direction Y can be 180mm-250mm, and the dimension of the heat dissipation module 110 along the third direction Z can be 120mm-180mm. This allows the heat dissipation module 110 to have both good heat dissipation performance and good assembly flexibility.

[0143] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an indirect connection through an intermediate medium, or the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application according to the specific circumstances.

[0144] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the embodiments of this application, and are not intended to limit them. Although the embodiments of this application have been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
