Description

Technical Field

[0001] This application relates to the field of electric vehicle technology, specifically to a heat dissipation charging base. Background Technology

[0002] The power terminals of a charging dock are typically connected to wires via crimping or soldering. When the current increases, concentrated heat is generated at the contact points of the conductors. If this heat cannot be dissipated in time, the conductor temperature will rise sharply, resulting in a decrease in charging power and accelerated oxidation of the power terminal material.

[0003] Therefore, how to provide a solution to overcome or alleviate the above-mentioned defects remains a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0026] To enable those skilled in the art to better understand the present invention, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] In the description of the embodiments of this application, it should be noted that the orientation or positional relationship indicated by "up", "down", "left", "right", "front", "back", etc. is based on the accompanying drawings and is only for the convenience of description, and is not intended to indicate or imply that the device referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0028] like Figure 1 , Figure 2 As shown, Figure 2 A schematic diagram of the structure of a heat dissipation charging base 1 in an embodiment of this application; Figure 2 for Figure 1 A cross-sectional view along the AA direction.

[0029] This application provides a heat dissipation charging base 1, including a charging module 11, a cooling module 12, and a housing 13. The charging module 11 is partially fixed inside the housing 13. The housing 13 includes a through hole 13a. The charging module 11 includes a conductor 111, which is located inside the housing 13. The through hole 13a is located on the side of the housing 13 closer to the conductor 111. The cooling module 12 is inserted into the through hole 13a and is in contact with the conductor 111.

[0030] A portion of the charging module 11 is fixed inside the housing 13. The charging module 11 includes a power terminal 112, a wire 113, and a conductor 111. The two ends of the conductor 111 are connected to the power terminal 112 and the wire 113, respectively. Figure 2 As shown, the left end of conductor 111 is connected to power terminal 112, the right end of conductor 111 is connected to wire 113, and conductor 111 is in contact with the inner wall surface of housing 13. Meanwhile, a through hole 13a is provided on the side of housing 13 near conductor 111, so that at least a portion of conductor 111 is exposed in the through hole 13a. Cooling module 12 is inserted into through hole 13a, making direct contact with conductor 111.

[0031] The cooling method of the cooling module 12 is not limited. In this embodiment, coolant is introduced into the cooling module 12. The coolant enters the cooling module 12 and reduces the temperature of the conductor 111. It can be understood that other cooling media, such as cooling gas, can also be used. This helps to ensure that the conductor 111 can carry a larger current at a safe temperature, improves the overcurrent capacity and charging power, and effectively controls the temperature of the conductor 111. This can avoid the risks of insulation aging, contact oxidation, melting, etc. caused by overheating of the charging socket, and improve the safety and durability of the charging socket under long-term high-load operation.

[0032] This embodiment does not limit the coolant; it can be a liquid with high specific heat capacity, high thermal conductivity, and insulating properties. For example, the coolant can be a special engineering coolant, which can ensure the efficiency and safety of the cooling module 12 when cooling the conductor 111.

[0033] In this embodiment, the heat dissipation charging base 1 is also provided with a signal component 114, which is fixed to the charging module 11, specifically to one side of the charging module 11 and the cooling module 12. Figure 2 The middle part is located above the charging module 11 and connected to the charging module 11. It is used to control the signal connection between the charging base and the charging device. This layout structure is relatively compact and not easy to interfere with.

[0034] In this embodiment, the cooling module 12 includes a module body 121 and a thermally conductive element. The thermally conductive element includes, but is not limited to, thermally conductive grease or thermally conductive pads. The thermally conductive grease or thermally conductive pads are fixed between the contact surface between the module body 121 and the conductor 111 of the cooling module 12. Based on the cooling of the conductor 111 by the module body 121, the contact thermal resistance between the conductor 111 and the cooling module 12 is reduced, thereby improving the heat conduction efficiency.

[0035] In some embodiments, the module body 121 specifically includes a cooling shell 1211, which has a cooling channel 1211c inside. The inner cavity of the cooling shell 1211 can serve as the cooling channel 1211c, and has a large contact area with the coolant. The cooling shell 1211 is inserted into the through hole 13a, and the aforementioned heat-conducting element can be arranged between the cooling shell 1211 and the conductor 111. Of course, it is also possible not to provide a heat-conducting element.

[0036] This embodiment does not limit the shape of the through hole 13a. For example, in this embodiment, the through hole 13a is a square through hole 13a, which is convenient for processing. Correspondingly, in this embodiment, the cooling shell 1211 is a square shell corresponding to the square through hole 13a, which is convenient for insertion or disassembly. The cooling shell 1211 can be a one-piece shell or a split shell; this embodiment does not limit this and can be selected according to actual installation requirements. In this embodiment, the cooling shell 1211 is a split shell, including a first shell 1211a and a second shell 1211b. The first shell 1211a and the second shell 1211b are distributed along a first direction, and the cooling shell 1211 is composed of the first shell 1211a and the second shell 1211b. The first direction is the distribution direction of the conductor 111 and the module body 121. The first direction can be referenced... Figure 2 As shown. The outer surface of the first housing 1211a is at least partially in contact with the conductor 111, as shown. Figure 2 As shown, the upper surface of the first housing 1211a is in contact with the lower surface of the conductor 111. A cooling channel 1211c is provided inside the cooling housing 1211, through which coolant flows to dissipate heat from the conductor 111.

[0037] In some embodiments, the cooling module 12 further includes at least two cooling water pipes 1212, which are fixed to one side of the cooling shell 1211 and communicate with the cooling channel 1211c. For example, this embodiment provides two cooling water pipes 1212, which are fixed to one side of the cooling shell 1211. (Refer to...) Figure 2 As shown, two cooling water pipes 1212 are fixed to the right side of the second housing 1211b. The cooling water pipes 1212 are connected to the cooling channel 1211c, and the two cooling water pipes 1212 and the cooling channel 1211c form a circulating cooling circuit. The coolant enters the cooling channel 1211c from one of the cooling water pipes 1212, comes into contact with the conductor 111, efficiently absorbs and removes the heat from the surface of the conductor 111, and then flows out from the other cooling water pipe 1212, providing rapid heat dissipation.

[0038] In some embodiments, the heat-dissipating charging base 1 may further include a heat dissipation module, which can be fixed to the side of the cooling water pipe 1212 away from the cooling shell 1211. Specifically, the left side of the cooling water pipe 1212 is connected to the cooling shell 1211, and a heat dissipation module (not shown in the figure) is provided on the right side of the cooling water pipe 1212. The heat dissipation module includes, but is not limited to, heat dissipation fins and a fan. When the coolant flows from one side of the cooling channel 1211c to the other side, it carries away most of the heat on the conductor 111. After flowing out from the other cooling water pipe 1212, the fan and heat dissipation fins of the heat dissipation module work together to quickly dissipate the heat carried by the coolant, dissipating the heat carried by the coolant into the surrounding environment. The cooled coolant then returns to one of the cooling water pipes 1212, and so on, to achieve continuous and active cooling of the conductor 111 and ensure heat conduction efficiency.

[0039] In some embodiments, the module body 121 further includes a water inlet 12121a, which is located at the connection between the cooling water pipe 1212 and the cooling shell 1211, and is used to connect the water pipe. A pumping device is also provided on the side of the cooling module 12 away from the charging module 11. The pumping device is connected to the water pipe. A water inlet 12121a is also provided at the connection between the cooling water pipe 1212 and the second shell 1211b. The water pipe is connected to the water inlet 12121a. The pumping device drives the coolant from the water inlet 12121a into the cooling channel 1211c, and simultaneously drives the coolant to flow between the cooling water pipe 1212 and the cooling channel 1211c.

[0040] For example, a current feedback device and a temperature sensor can be connected to the fan and pump of the heat dissipation device, respectively. The fan and pump can be intelligently speed-adjusted according to the actual charging current and temperature feedback. When charging at low power, the fan and pump can be operated in a low-efficiency mode to reduce noise and energy consumption. When charging at high power, the fan and pump can be automatically upgraded to maximize heat dissipation efficiency.

[0041] In some embodiments, the cooling water pipe 1212 includes a connecting section 12121 and a water pipe section 12122. One end of the connecting section 12121 is inserted into the water pipe section 12122, and the other end of the connecting section 12121 is inserted into the cooling shell 1211 and communicates with the cooling channel 1211c. The water inlet 12121a is located in the connecting section 12121. A connecting section 12121 is also provided between the water pipe section 12122 and the second shell 1211b. (Refer to...) Figure 2 As shown, the left end of the connecting section 12121 is inserted into the interior of the second housing 1211b and communicates with the cooling channel 1211c. The right end of the connecting section 12121 is inserted into the interior of the water pipe section 12122, which facilitates the installation and disassembly of the water pipe section 12122.

[0042] In some embodiments, the cooling module 12 further includes a fixing component 122, which includes a seal 1221 and a fastener 1222. The seal 1221 is disposed at the connection between the connecting section 12121 and the cooling shell 1211; the fastener 1222 is disposed at one end of the water pipe section 12122 connecting to the connecting section 12121. The seal 1221 is inserted into one end of the connecting section 12121, and then the end of the connecting section 12121 with the seal 1221 inserted is inserted into the second shell 1211b, thereby connecting the connecting section 12121 and the cooling channel 1211c. This embodiment does not limit the fastener 1222. For example, the seal 1221 is a sealing ring. The sealing ring is inserted into one end of the connecting section 12121, and then the connecting section 12121 is inserted into the second shell 1211b to prevent the connecting section 12121 from falling off. The other end of the water pipe segment 12122 is inserted into the interior of the connecting segment 12121. The fastener 1222 is fixed at the insertion point of the connecting segment 12121 and the water pipe segment 12122, thus fixing the water pipe segment 12122 and the connecting pipe. In this embodiment, the fastener 1222 is not limited. For example, the fastener 1222 is a fastening buckle. The fastening buckle is used to fix the water pipe segment 12122 and the connecting pipe to prevent the connecting segment 12121 and the water pipe segment 12122 from falling off when the coolant is flowing.

[0043] like Figure 3 , Figure 4 and Figure 5 As shown, Figure 3 for Figure 2 Exploded view; Figure 4 This is a schematic diagram of the structure of module body 121 in the embodiments of this application; Figure 5 for Figure 4 A bottom view.

[0044] In some embodiments, the cooling housing 1211 includes a protrusion 12111 located on the side of the cooling housing 1211 away from the conductor 111, and the protrusion 12111 at least partially extends through a through hole 13a; a cooling water pipe 1212 is connected to the protrusion 12111. (Reference) Figure 3As shown, a protrusion 12111 is provided on the side of the second housing 1211b away from the first housing 1211a along the first direction. The protrusion 12111 extends downward along the first direction, at least partially extending out of the through hole 13a. In this embodiment, two cooling water pipes 1212 are provided, and correspondingly, two protrusions 12111 are provided on the second housing 1211b. The two cooling water pipes 1212 are respectively connected to the two protrusions 12111 to avoid interference between the cooling water pipes 1212 and the outer shell 13. A flow channel is provided inside the protrusion 12111. The flow channel extends along the first direction. One end of the flow channel is connected to the cooling channel 1211c, and the other end is connected to the cooling water pipe 1212. Coolant enters the flow channel from the cooling water pipe 1212 and then enters the cooling channel 1211c from the flow channel.

[0045] In some embodiments, the cooling shell 1211 is provided with a connecting portion 12112; the heat dissipation charging base 1 also includes a connector 15, which is inserted into the connecting portion 12112 and the outer shell 13 to fix the module body 121 and the outer shell 13. Because the cooling shell 1211 is a split design in this embodiment, the first shell 1211a and the second shell 1211b are respectively provided with corresponding connecting portions 12112, and the connecting portion 12112 of the first shell 1211a is defined as the first connecting portion, and the connecting portion 12112 of the second shell 1211b is defined as the second connecting portion. Combined with... Figure 3 As shown, the connector 15 is inserted from below into the connecting portion 12112 and the outer shell 13 of the cooling shell 1211, fixing the module body 121 and the outer shell 13. Specifically, the connector 15 is sequentially inserted into the second connecting portion, the first connecting portion, and the outer shell 13 to fix the module body 121 and the outer shell 13. In this embodiment, combined with Figure 4 As shown, a first connecting part is provided on the left and right sides of the first housing 1211a along the first direction. Correspondingly, a second connecting part is provided on the left and right sides of the second housing 1211b along the first direction. After the cooling shell 1211 is inserted into the through hole 13a, the fastener 1222 is inserted into the second connecting part, the first connecting part and the outer shell 13 in sequence along the first direction to fix the module body 121 and the outer shell 13.

[0046] In some embodiments, the heat dissipation charging base 1 further includes a protective member 14, which is provided between the cooling shell 1211 and the through hole 13a, and is fixed to the outer wall surface of the cooling shell 1211. Figure 4As shown, protective members 14 are provided around the outer wall of the first housing 1211a. In this embodiment, the protective members 14 are not limited. For example, the protective member 14 is a protective ring. The protective ring is fitted onto the outer wall of the first housing 1211a. After the cooling shell 1211 is inserted into the through hole 13a, the protective member 14 is located between the through hole 13a and the first housing 1211a. This is used to prevent the coolant or liquid from seeping into the connection between the cooling module 12 and the conductor 111 in rainy or snowy weather, thus affecting the charging module 11.

The descriptions of the embodiments above are only for the purpose of helping to understand the method and core ideas of this application.
