Description

Technical Field

[0001] The utility model relates to a heat dissipation component and a charging socket, belonging to the field of electrical equipment. Background Art

[0002] Generally speaking, when connecting one electrical device to another, one approach is to mate the connector of one device with the mating connector of the other. For example, a car's charging plug and charging socket are typical examples of a connector and a mating connector.

[0003] In recent years, with the popularity of new energy vehicles, automotive charging sockets have become an indispensable component. However, compared to refueling fuel vehicles, charging sockets take longer to charge, generating significant heat. Furthermore, with increasing demands for shorter charging times, high-current fast charging is becoming increasingly common, which in turn generates significant heat in the charging conductors. Generally speaking, in charging socket designs, as a countermeasure to high-current fast charging, the mainstream approach is to increase the cross-sectional area of ​​the charging conductors to reduce temperature rise and thus meet temperature rise requirements.

[0004] However, as the market demands for faster charging speeds, charging currents increase in a short period of time, and conductors cannot be continuously thickened and enlarged. Moreover, enlarging the conductor not only increases the cost of the product, but also increases the size and weight of the product.

[0005] Therefore, how to meet the temperature rise requirements without increasing the cross-sectional area of ​​the charging conductor is an issue that needs to be solved. Utility Model Content

[0006] In order to solve the problems in traditional charging sockets, the utility model provides a heat dissipation component and a charging socket, which can reduce the temperature of the charging conductor of the charging socket during operation without increasing the cross-sectional area of ​​the charging conductor (wire, bus bar, aluminum rod, etc.) of the charging socket, thereby achieving good temperature rise performance.

[0007] Specifically, a first aspect of the present invention provides a heat dissipation component for installation in a charging socket to dissipate heat from a charging conductor in the charging socket, the heat dissipation component comprising:

[0008] A heat dissipation block having a cooling flow path formed therein for circulating a coolant;

[0009] a liquid inlet, the liquid inlet being provided at one end of the cooling flow path for allowing coolant to flow into the cooling flow path; and

[0010] a liquid outlet, the liquid outlet being provided at the other end of the cooling flow path for allowing the coolant to flow out of the cooling flow path;

[0011] The heat dissipation block, when installed in the charging socket, has one or more heat dissipation surfaces in contact with at least one side of the thickness direction of the charging conductor, and

[0012] Wherein, at least on the outer surface of the heat dissipation surface, an insulating sheet is provided along the outer surface.

[0013] The heat sink component, with the aforementioned structure, is incorporated into a charging socket to dissipate heat from the charging conductor, the primary heat source within the socket, without increasing the cross-sectional area of ​​the charging conductor itself. This allows the charging socket to be compact and lightweight, even when charging at high currents. Furthermore, the heat sink component's simple structure and low production cost can reduce product costs while maintaining comparable performance. Furthermore, this embodiment utilizes a single heat sink component for heat dissipation, making maintenance easier. Compared to conductor-embedded cooling devices, if the heat sink component fails, only the heat sink component needs to be replaced, eliminating the need to replace the entire charging socket or conductor. Furthermore, the heat sink component has one or more heat dissipation surfaces that contact at least one side of the charging conductor's thickness, enabling heat dissipation over a larger contact area and improving temperature rise performance. Furthermore, the insulating sheet provided on the outer surface of the heat sink component ensures insulation between the heat sink component and the charging conductor, even when the heat sink component is made of relatively low-cost metal.

[0014] Preferably, in the heat dissipation component of the first aspect, the heat dissipation block further includes: a liquid inlet joint, one end of which is watertightly installed on the liquid inlet, and the other end of the liquid inlet joint can be connected to a cooling water pipe of the coolant supply part, so that the coolant flows to the liquid inlet through the liquid inlet joint; a liquid outlet joint, one end of which is watertightly installed on the liquid outlet, and the other end of the liquid outlet joint can be connected to another cooling water pipe of the coolant supply part, so that the coolant flows out from the liquid outlet through the liquid outlet joint.

[0015] According to the heat dissipation component with the above-mentioned structure, the heat dissipation component can be connected to the cooling water pipe of the coolant supply part through a simple structure by using the liquid inlet joint and the liquid outlet joint. The connection between the heat dissipation component and the coolant supply part becomes more stable and reliable, which not only ensures that the coolant can circulate smoothly inside the heat dissipation component, but also improves the safety of the entire heat dissipation system and reduces the risk of leakage, so that the heat dissipation component can better meet the heat dissipation needs of equipment such as charging sockets and ensure the stable operation of the equipment.

[0016] Preferably, in the heat dissipation component of the first aspect, the liquid inlet joint and the liquid outlet joint are respectively formed integrally with the liquid inlet and the liquid outlet.

[0017] According to the heat dissipation component having the above structure, since the liquid inlet and outlet connectors are integrally formed with the liquid inlet and outlet, respectively, the structure is strong. There are no additional connection points between the liquid inlet and outlet, nor between the liquid outlet and outlet, thereby reducing the risk of leakage and enhancing safety. Furthermore, considering factors such as molding costs, the aforementioned method of watertightly attaching the liquid inlet and outlet connectors to the liquid inlet and outlet, such as by welding or bonding, is also feasible. This helps reduce manufacturing costs and simplifies the production process to a certain extent.

[0018] Preferably, in the heat dissipation component of the first aspect, the liquid inlet joint and the liquid outlet joint respectively include a flexible portion.

[0019] According to the heat dissipation component having the above structure, since the liquid inlet connector and the liquid outlet connector each include a flexible portion, the liquid inlet connector and the liquid outlet connector are allowed to bend and deform within a certain range, making the heat dissipation component more flexible during installation and layout, and better adapting to various complex or compact spatial layouts, ensuring that the heat dissipation component can be smoothly installed and connected to the coolant supply unit. At the same time, the use of the flexible portion also makes disassembly and reinstallation easier and faster during equipment maintenance or component replacement. In addition, the flexible portion can also enable the installation location of the liquid inlet connector and the liquid outlet connector and the cooling water pipe to more effectively absorb stress, avoiding damage caused by excessive stress concentration at the installation location. Moreover, the flexible portion is also conducive to absorbing vibration, improving the stability and reliability of the system. Even if there is insufficient space for a straight connection, the connection can be achieved by bending the flexible portion.

[0020] Preferably, in the heat dissipation component of the first aspect, the heat dissipation block has a flat shape and includes: a lower plate, on which the liquid inlet and the liquid outlet are formed; a waterway plate stacked on the upper side of the lower plate, in which the cooling flow path is provided; and an upper plate stacked on the upper side of the waterway plate, the upper plate covering the cooling flow path. The lower plate, the waterway plate, and the upper plate are formed separately and integrated by welding or bonding. Alternatively, the heat dissipation block has a flat shape and includes an upper plate and a lower plate that are formed separately and integrated by welding or bonding, and at least one of the upper plate and the lower plate has a recess formed to serve as the cooling flow path.

[0021] According to the heat dissipation component with the above structure, the heat dissipation block adopts a flat shape design, which helps the heat dissipation component better adapt to various compact systems. This is especially important for scenarios with limited space. As long as there is a gap space, it can be installed on the charging conductors inside various charging sockets, such as bus bars (parallel, staggered, overlapping, as long as there is a hole). It has strong versatility and can be installed on one side or both sides according to needs. In addition, the heat dissipation component is composed of, for example, a lower plate, a waterway plate, and an upper plate, that is, it forms a multi-layer structure. Therefore, the heat dissipation block can be expanded or reduced according to actual needs. For example, the heat dissipation capacity can be adjusted by increasing or decreasing the number of waterway plates to adapt to systems with different power.

[0022] Preferably, in the heat dissipation component according to the first aspect, the upper plate serves as the heat dissipation surface, and the insulating sheet is provided on an outer surface of the upper plate.

[0023] According to the heat dissipation component having the above-mentioned structure, since the upper plate becomes the heat dissipation surface, when the heat dissipation component is installed, the charging conductor, such as the bus bar, is arranged above the heat dissipation component in close contact with the heat dissipation component, so that the heat dissipation component can be positioned by using the charging conductor itself without providing an additional positioning structure, and the operability is high.

[0024] Preferably, in the heat dissipation component of the first aspect, the heat dissipation block has a U-shaped cross-sectional shape, so that an opening for inserting the charging conductor is formed in the center of the heat dissipation block of the cross-sectional shape.

[0025] According to the heat dissipation component having the above-mentioned structure, since the heat dissipation block has a U-shaped cross-section and an opening is formed in the center for inserting a charging conductor such as a bus bar, the surface around the opening of the heat dissipation block becomes a heat dissipation surface, the heat dissipation area is large, and the heat dissipation effect is improved. Moreover, when the heat dissipation component is installed, the charging conductor inserted in the opening itself can be used to achieve the positioning and installation of the heat dissipation component without providing an additional positioning structure, and the operability is high.

[0026] A second aspect of the present invention provides a charging socket having:

[0027] case;

[0028] a bus bar mounted on the housing, serving as the charging conductor; and

[0029] The heat dissipation component according to the first aspect is mounted in the housing, and is provided at a position in contact with the bus bar.

[0030] According to the charging socket of the second aspect, since it is provided with the heat dissipation component of the first aspect, accordingly, the various technical effects mentioned in the first aspect can also be achieved.

[0031] Preferably, in the charging socket of the second aspect, the housing comprises:

[0032] an insertion opening provided on a peripheral wall of the housing, wherein the bus bar is inserted into the housing via the insertion opening;

[0033] a bus bar mounting portion to which the bus bar inserted into the housing is fixed via a fastening member; and

[0034] a heat dissipation component mounting portion, the heat dissipation component mounting portion being located between the socket portion and the bus bar mounting portion, and the heat dissipation component being mounted in the heat dissipation component mounting portion,

[0035] The heat dissipation component is positioned on the heat dissipation component mounting portion by the bus bar in the thickness direction of the bus bar.

[0036] According to the charging socket having the above structure, while the busbar is fixed to the busbar mounting portion using fastening components such as screws and clips, the heat dissipation component can also be positioned accordingly in the heat dissipation component mounting portion. That is, in addition to serving as a charging conductor, the busbar can also serve as a positioning component for positioning the heat dissipation component. The structure is simple, the operation is convenient, and the cost is low.

[0037] Preferably, in the charging socket of the second aspect, there are two or more bus bars arranged side by side, and the heat dissipation member is arranged across the two or more bus bars.

[0038] According to the charging socket having the above structure, a heat dissipation component is used to span across multiple bus bars, and the heat is dissipated from the multiple bus bars at the same time, which makes the structure more efficient and convenient, and makes installation more convenient.

[0039] Preferably, in the charging socket according to the second aspect, the heat dissipation member is connected to a cooling water pipe provided in a cooling system of the vehicle's battery pack, so that the cooling water pipe communicates with the cooling flow path.

[0040] According to the charging socket with the above structure, the flow of coolant in the heat dissipation component is achieved through the cooling system of the battery pack, and there is no need to supply coolant separately for the charging socket. This not only simplifies the heat dissipation system of the charging socket, but also improves the efficiency and reliability of the overall system. In this way, the coolant can be circulated between the battery pack and the charging socket, without the need for additional coolant storage and supply equipment, so that the structure of the charging socket can be more compact and simple, which not only reduces manufacturing costs, but also improves the reliability and maintainability of the system. Moreover, directly using the cooling water of the battery pack for cooling reduces energy consumption and environmental pollution, and reduces dependence on and waste of natural resources.

[0069] Hereinafter, the specific embodiments of the present invention will be described with reference to the accompanying drawings to more clearly illustrate the technical solutions of the present invention.

[0070] It should be noted that the drawings in the present invention are merely schematic diagrams for the purpose of clearly illustrating the parts related to the solution of the present invention, and do not show some non-essential parts that may exist. Therefore, these drawings should not be understood as limiting the present invention, and may differ from the actual structure when in use. In addition, it should be understood that the terms "upper", "lower", "left", "right", "front", "back", etc. that may appear in the following description to indicate direction or position are for the purpose of convenience of explanation and are not restrictive. Similarly, for the sake of clarity and conciseness, the description of well-known functions and structures is omitted in the following description.

[0071] The utility model provides a heat dissipation component that can be used in a charging socket, especially a charging socket of a vehicle, which can dissipate heat from a bus bar or the like that serves as a charging conductor in the charging socket, thereby correspondingly reducing the temperature of the charging socket during operation and achieving good temperature rise performance.

[0072] Figure 1 is a schematic exploded view of a heat dissipation component 100 according to an embodiment of the present invention; Figure 2 is a schematic diagram of a heat dissipation component 100 according to an embodiment of the present invention, wherein (A) is a view before assembling the insulating sheet 50, and (B) is a view after assembling the insulating sheet 50; and Figure 3 Schematic diagram of the coolant flow of the heat dissipation component 100 according to an embodiment of the present invention.

[0073] like Figure 1-Figure 3As shown, the heat dissipation component 100 of the present invention includes: a lower plate 30, in which a liquid inlet 31 for the coolant to flow in and a liquid outlet 32 ​​for the coolant to flow out are formed; a waterway plate 20 stacked on the upper side of the lower plate 30, in which a cooling flow path 21 for the coolant to circulate is provided; and an upper plate 30 stacked on the upper side of the waterway plate 20, which watertightly covers the cooling flow path 21.

[0074] In this embodiment, the cooling channel 21 in the water channel plate 20 is as follows Figure 1 The through groove shown runs through the waterway plate 20 in the vertical direction. When the waterway plate 20 is watertightly mounted on the lower plate 30, the liquid inlet 31 is located at one end of the through groove, and the liquid outlet 32 ​​is located at the other end of the through groove. Thus, the through groove extends between the liquid inlet 31 and the liquid outlet 32, allowing the coolant to circulate between the liquid inlet 31, the cooling channel 21, and the liquid outlet 32.

[0075] In this embodiment, the lower plate 30, the waterway plate 20 and the upper plate 10 can be made of metal materials such as aluminum, but this is not restrictive. As long as they are thermally conductive materials, they can be selected based on cost and performance requirements. Figure 2 As shown, the lower plate 30, the waterway plate 20, and the upper plate 10 are watertightly joined together during use. This joining may be accomplished by ultrasonic welding, adhesive bonding, or the like. The assembled lower plate 30, waterway plate 20, and upper plate 10 form a heat sink having cooling channels 21 formed therein for the circulation of coolant.

[0076] However, it should be noted that the heat sink block does not necessarily have to be composed of three layers, namely, a lower plate, a water channel plate, and an upper plate, as described above. For example, a structure in which a concave cooling flow path is formed on the lower plate and the lower plate is directly coupled to the upper plate can also be used. For example, a structure in which a concave cooling flow path is formed on the upper plate and the upper plate is directly coupled to the upper plate can also be used. A structure in which both the lower plate and the upper plate have concave cooling flow paths and the lower plate is coupled to the upper plate can also be used. A structure in which only a lower plate is provided with a cooling flow path formed inside the lower plate (i.e., the lower plate is hollow) can also be used. In other words, as long as a cooling flow path for the coolant to circulate can be formed inside the heat sink block, the specific structure of the heat sink block is not limited.

[0077] Of course, in this embodiment, the heat sink block, constructed from a layered structure consisting of a lower plate, a waterway plate, and an upper plate, can be expanded or reduced based on actual needs. For example, the heat dissipation capacity can be adjusted by increasing or decreasing the number of waterway plates to accommodate systems of varying power. Furthermore, in this embodiment, cooling channels are not provided on the upper and lower plates. However, recessed portions could be provided on the lower surface of the upper plate and the upper surface of the lower plate to serve as cooling channels, thereby improving heat dissipation capacity.

[0078] In addition, in this embodiment, Figure 2The heat sink block of the heat sink component 100 has a flat shape. This flat design helps the heat sink component better adapt to various compact systems, which is particularly important for scenarios with limited space. As long as there is a gap, it can be installed on the busbars inside various charging sockets (parallel, staggered, overlapping, or any place with a hole). It is highly versatile and can be installed on one side or both sides as needed.

[0079] In addition, if Figure 2 and Figure 3 As shown, in the heat dissipation component 100, the heat dissipation block may further include: a liquid inlet joint 41, one end of which is watertightly mounted on the liquid inlet 31, and the other end of the liquid inlet joint 41 can be connected to a cooling water pipe of a coolant supply part (for example, a cooling system of a battery pack described later), so that the coolant flows to the liquid inlet 31 through the liquid inlet joint 41; a liquid outlet joint 42, one end of which is watertightly mounted on the liquid outlet 32, and the other end of the liquid outlet joint 42 can be connected to another cooling water pipe of a coolant supply part (for example, a cooling system of a battery pack described later), so that the coolant flows out from the liquid outlet 32 ​​through the liquid outlet joint 42.

[0080] According to the heat dissipation component 100 having the above-mentioned structure, the heat dissipation component can be connected to the cooling water pipe of the coolant supply part through a simple structure by using the liquid inlet connector 41 and the liquid outlet connector 42. The connection between the heat dissipation component and the coolant supply part becomes more stable and reliable, which not only ensures that the coolant can circulate smoothly inside the heat dissipation component, but also improves the safety of the entire heat dissipation system and reduces the risk of leakage, so that the heat dissipation component can better meet the heat dissipation requirements of equipment such as charging sockets and ensure the stable operation of the equipment. In this embodiment, the watertight connection between the liquid inlet connector 41 and the liquid inlet 31 can be completed by ultrasonic welding, for example; the watertight connection between the liquid outlet connector 42 and the liquid outlet 32 ​​can also be completed by ultrasonic welding, for example. Of course, other watertight connection methods are also feasible, such as bonding. In addition, in addition to watertight installation, the liquid inlet connector 41 and the liquid inlet 31 can be integrally formed, and the liquid outlet connector 42 and the liquid outlet 32 ​​can also be integrally formed. The integral forming has no installation point and has better watertightness.

[0081] The liquid inlet connector 41 and the liquid outlet connector 42 in the heat dissipation component 100 can be made of the same metal material as the heat dissipation block, such as aluminum, or different materials. In addition, the liquid inlet connector 41 and the liquid outlet connector 42 can each include a flexible portion so as to be bendable.

[0082] Since the liquid inlet connector 41 and the liquid outlet connector 42 are flexible parts, they are allowed to bend and deform within a certain range, making the heat dissipation component more flexible during installation and layout, and better adapting to various complex or compact spatial layouts, ensuring that the heat dissipation component can be smoothly installed and connected to the coolant supply part. At the same time, the use of the flexible part also makes disassembly and reinstallation easier and faster during equipment maintenance or component replacement. In addition, the flexible part can also make the installation part of the liquid inlet connector and the liquid outlet connector and the cooling water pipe more effectively absorb stress, avoiding damage caused by excessive stress concentration at the installation part. In addition, the flexible part is also conducive to absorbing vibrations, improving the stability and reliability of the system. Even if there is not enough space for a straight connection, the connection can be achieved by bending the flexible part.

[0083] According to the heat dissipation component 100 of this embodiment, Figure 2 As shown, an insulating sheet 50 is also attached to the upper surface of the upper plate 10 of the heat sink block. The insulating sheet 50 is a sheet made of an insulating, thermally conductive material. According to this embodiment, when the heat sink 100 is mounted on the housing 300 of the charging socket 1, the upper plate 10 forms the contact surface with the busbar 200, which serves as the charging conductor (described later). Therefore, the insulating sheet 50 provided on the upper surface of the upper plate 10 provides electrical insulation between the heat sink 100 and the busbar 200, preventing short circuits.

[0084] like Figure 3 As shown, during use, coolant from the vehicle battery pack cooling system flows from the liquid inlet connector 41 to the heat sink block as indicated by the arrows, enters the cooling flow path from the liquid inlet and flows there, flows to the liquid outlet and flows out through the liquid outlet connector 42. The motor in the battery pack coolant circulation system continuously repeats the above-mentioned circulation of coolant, thereby removing heat from the bus bar 200 in contact with the heat sink component 100, thereby cooling and dissipating heat from the bus bar 200.

[0085] The structure of the heat sink component 100 according to an embodiment of the present invention has been generally described above. By applying this heat sink component to the charging socket 1 described below, the heat sink component can dissipate heat from the charging conductor (in this embodiment, the busbar), the primary heat source within the charging socket, without increasing the cross-sectional area of ​​the charging conductor. This ensures a compact and lightweight charging socket even when charging at high currents. Furthermore, the heat sink component's simple structure and low production cost can reduce product costs while maintaining comparable performance. Furthermore, using the heat sink component alone for heat dissipation facilitates maintenance. Compared to conductor-embedded cooling devices, if the heat sink component fails, only the heat sink component needs to be replaced, eliminating the need to replace the entire charging socket or conductor. Furthermore, the heat sink component has one or more heat dissipation surfaces that contact at least one side of the charging conductor in its thickness direction. This allows for heat dissipation over a larger contact area, improving temperature rise performance. Furthermore, because the outer surface of each heat sink surface is provided with an insulating sheet, insulation between the heat sink component and the charging conductor is ensured, even when the heat sink component is formed from a relatively low-cost metal.

[0086] The following describes a charging socket 1 according to an embodiment of the present invention. The charging socket 1 is, for example, a charging socket 1 for a vehicle, particularly a new energy vehicle. By inserting a charging plug into the charging socket 1, the charging plug is electrically connected to the charging conductor in the charging socket, thereby charging the battery pack.

[0087] Figure 4 is a schematic exploded view of a charging socket 1 according to an embodiment of the present utility model; Figure 5 Figure 1 is a schematic diagram of an assembled charging socket 1 according to an embodiment of the present invention, with (A) being a top view and (B) being a cross-sectional view. As shown, the charging socket 1 comprises: a housing 300; a busbar 200 mounted within the housing 300, the busbar 200 being an example of a charging conductor; and a heat sink 100 mounted within the housing 300, positioned in contact with the busbar 200.

[0088] As shown in the figure, the shell 300 includes: a socket portion 320 arranged on the peripheral wall of the shell 300, and the bus bar 200 is inserted into the shell 300 through the socket portion 320; bus bar mounting portions 341, 342 (in this embodiment, 2 are set corresponding to the bus bar 200), and the bus bar 200 inserted into the shell 300 is fixed to the bus bar mounting portions 341, 342 by fastening a fastening component such as a screw 400 to the mounting hole 210 of the bus bar 200; and a heat dissipation component mounting portion 310, which is located between the socket portion 320 and the bus bar mounting portions 341, 342, and the heat dissipation component 100 is installed in the heat dissipation component mounting portion 310.

[0089] In this embodiment, if Figure 4 As shown, the heat dissipation component mounting portion 310 can be a through hole portion, and the heat dissipation component 100 can be accommodated in the through hole portion, so that when the heat dissipation component 100 has been accommodated in the through hole portion, the upper surface of the heat dissipation component 100 is flush with the mounting surfaces of the bus bar mounting portions 341 and 342. Therefore, the heat dissipation component 100 will neither hinder the subsequent insertion of the bus bar 200 nor be able to fully contact the bus bar 200 when the bus bar 200 is installed in the bus bar mounting portions 341 and 342.

[0090] When assembling the charging socket 1 of this embodiment, the heat sink 100 can be first placed in the heat sink mounting portion 310. Then, the two busbars 200 are respectively inserted through the socket portion 320 and the mounting holes 210 of the two busbars 200 are fastened to the corresponding busbar mounting portions 341 and 342 using screws 400. At this point, the busbars 200 are positioned above the heat sink 100, and their lower surfaces in the thickness direction of the busbars 200 are in contact with the heat sink 100. While heat is dissipated through contact, the busbars 200 also secure the heat sink 100 in place. In other words, the heat sink 100 can be secured to the heat sink mounting portion 310 in the thickness direction of the busbars 200 using the busbars 200. Finally, the cover 500 is placed over the housing 300, completing the assembly.

[0091] According to the charging socket 1 having the above structure, while the busbar 200 is fixed to the busbar mounting portions 341 and 342 using the screws 400, the heat dissipation component 100 can also be correspondingly positioned in the heat dissipation component mounting portion 310. That is, in addition to serving as a charging conductor, the busbar 200 can also serve as a positioning component for positioning the heat dissipation component 100. The busbar 200 itself can be used to position and install the heat dissipation component 100 without the need to provide other positioning structures to position the heat dissipation component 100. The structure is simple, the operation is convenient, and the cost is low. Moreover, the busbar 200 is arranged in close contact with the heat dissipation component 100 and above the heat dissipation component 100, which can also effectively dissipate heat.

[0092] As shown in the figure, in this embodiment, two busbars 200 are arranged side by side, and the heat sink 100 is arranged across the two busbars. With this structure, the charging socket 1 uses a single heat sink 100 that spans multiple busbars, dissipating heat from multiple busbars simultaneously. This provides a more efficient and convenient structure and facilitates installation. Compared to installing a heat sink for each charging conductor, this design is simpler and more user-friendly.

[0093] Furthermore, in the charging socket 1 of this embodiment, the heat dissipating component 100 is connected to a cooling water pipe provided in a cooling system of a vehicle battery pack, so that the cooling water pipe communicates with the cooling flow path of the heat dissipating component 100 .

[0094] According to the charging socket 1 having the above-described structure, the flow of coolant in the heat sink 100 is achieved through the vehicle battery pack's cooling system, eliminating the need for a separate coolant supply for the charging socket 1. This not only simplifies the heat sink 1's heat dissipation system but also improves the efficiency and reliability of the overall system. In this way, coolant can be circulated between the battery pack and the charging socket 1, eliminating the need for additional coolant storage and supply equipment. This makes the charging socket 1 more compact and simpler, reducing manufacturing costs and improving system reliability and maintainability. Furthermore, directly utilizing the battery pack's cooling water for cooling reduces energy consumption and environmental pollution, reducing dependence on and waste of natural resources. During use, for example, simply branching a pipeline from the vehicle battery pack's cooling water system's cooling water pipe and connecting it to the inlet and outlet connectors of the heat sink can provide coolant to the heat sink and drive the coolant to circulate.

[0095] The heat dissipation component and charging socket of the embodiment of the present invention have been described above. Figure 6 A modified example of the heat dissipation component 100 according to the embodiment of the present invention will be described.

[0096] Figure 6 FIG. 1 is a schematic diagram of a modified example of a heat dissipation component according to an embodiment of the present invention, which schematically shows the flow of the cooling liquid. Figure 6 As shown, unlike the flat shape of the heat dissipation member in the embodiment, the heat dissipation member in this modification is formed to have a U-shaped cross-sectional shape, so that an opening for inserting the bus bar 200 is formed in the center of the heat dissipation block.

[0097] The heat sink 100 in the modified example can also be constructed by combining three layers of plates, similar to the embodiment, with an insulating layer 50 attached to the surface of the opening that contacts the busbar 200. Of course, the heat sink 100 in the modified example can also be constructed of something other than three layers of plates, such as a hollow rectangular ring, as long as a cooling channel for the coolant is formed within.

[0098] In addition, the U-shaped cross section mentioned in this embodiment, in addition to the U-shaped cross section shown in the figure, also includes the case where one side of the U-shaped cross section is slightly broken so that it is basically a U-shaped cross section.

[0099] According to the heat dissipation component 100 of the modified example, since the heat dissipation block has a U-shaped cross-section and an opening for inserting the busbar is formed in the center, the surface around the opening of the heat dissipation block becomes a heat dissipation surface, the heat dissipation area is large, and the heat dissipation effect is improved.

[0100] When installing the heat sink, as in the embodiment, the heat sink is first placed in the heat sink mounting portion. Unlike in the embodiment, the upper surface of the heat sink is not flush with the mounting surface of the busbar mounting portion. Instead, the heat sink protrudes from the busbar mounting surface, so that the central opening of the heat sink is substantially aligned with the socket portion of the housing. The busbar is then inserted through the socket portion and further inserted through the central opening of the heat sink until the busbar mounting hole is in the busbar mounting position. The busbar is then screwed to the busbar mounting portion, and the heat sink is also secured in place. Therefore, as in the embodiment, the heat sink can be positioned and installed using the busbar inserted into the opening of the heat sink, without the need for an additional positioning structure to position the heat sink, resulting in improved operability.

[0101] The above specific embodiments do not limit the scope of protection of this utility model. Those skilled in the art will understand that various modifications, combinations, sub-combinations, and substitutions may occur depending on design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model shall be included in the scope of protection of this utility model.

[0102] For example, in the above embodiment, the number of bus bars is 2, but it can be set to more than 2 as needed; for example, the thickness and width of the heat sink of the heat dissipation component are not limited to those shown in the figure, and the cooling flow path is not limited to the shape shown in the figure, but can be set according to the actual layout space, and the volume of the heat sink of the heat dissipation component and the volume of the cooling flow path can be adjusted, thereby adjusting the flow rate of the coolant to ensure the best cooling effect; for example, in the above embodiment, the heat dissipation component is connected to the cooling water pipe of the vehicle battery pack cooling system through the liquid inlet joint and the liquid outlet joint, however, the liquid inlet joint and the outlet joint can also be not provided, so that the pipe branched from the cooling water pipe of the cooling system Directly watertightly connected to the liquid inlet and outlet of the cooling block; for example, in this embodiment, the charging conductor is described by taking the bus bar as an example, however, it can be understood that the heat dissipation component of the present invention is also applicable to charging conductors such as wires and aluminum bars; for example, in this embodiment, only one heat dissipation component is provided, however, according to actual conditions, multiple heat dissipation components can also be provided, and in addition to being provided below the bus bar in the embodiment, the heat dissipation component can also be provided above it; for example, in this embodiment, the top view plane of the heat dissipation component is shown in the figure as a regular rectangle, but this is not restrictive, and it can also have other shapes and can be set according to the installation space. For example, in the embodiment, the liquid inlet and liquid outlet joints are in a cross form with the cooling flow path, but this is not restrictive, and it can also be provided in a straight-in and straight-out form with the liquid inlet joint, cooling flow path and liquid outlet joint on the same straight line.
