[0029] Referring to Figure 1 , which shows a schematic diagram of the electric equipment 1 provided by an embodiment of the present application. The electric equipment 1 includes a charging pile 1000, and the charging pile 1000 includes a charging module 100 installed in the charging pile 1000. The charging module 100 is used to connect with other electronic devices and provide electric energy. Accordingly, the electric equipment 1 in the embodiments of the present application includes but is not limited to the charging pile 1000, and can also be other electric equipment. The structure of the charging module 100 will be further described below.

[0030] For the foregoing charging module 100, refer to Figures 2-5 , which respectively shows a perspective view of the charging module 100 provided by an embodiment of the present application, an exploded view of the charging module 200 provided by an embodiment of the present application, and a schematic diagram of the charging module 300 provided by an embodiment of the present application. Figure 2A cross-sectional view of the A side, the charging module 100 provided by an embodiment of the present application is partially exploded, and is combined with other drawings. The charging module 100 comprises a housing 10, a heat dissipation mechanism 20 and a charging module 30. The heat dissipation mechanism 20 comprises a heat dissipation plate 21 and a cover plate 22, the heat dissipation plate 21 is installed in the housing 10, the cover plate 22 is covered on the heat dissipation plate 21, and the cover plate 22 and the heat dissipation plate 21 jointly enclose a heat dissipation cavity 23, two ends of the heat dissipation cavity 23 are communicated with the external environment, the heat dissipation cavity 23 is used for circulating a heat conduction medium, and the heat dissipation plate 21 seals and isolates the housing 10 into a first containing cavity 11 and a second containing cavity 12 located on both sides of the heat dissipation plate. The charging module 30 comprises a first charging element 31 and a second charging element 32, the first charging element 31 and the second charging element 32 are arranged on both sides of the heat dissipation plate 21 respectively, the first charging element 31 is installed on one side of the cover plate 22 and / or the heat dissipation plate 21 towards the first containing cavity 11, the second charging element 32 is installed on one side of the heat dissipation plate 21 towards the second containing cavity 12, the heat dissipation cavity 23 is used for dissipating heat for the first charging element 31 and the second charging element 32, and the first containing cavity 11 and the second containing cavity 12 are arranged by being separated by the heat dissipation cavity, so that the electronic elements are regionally dissipated. The heat conduction medium comprises a gas, water, a cooling liquid and the like, and the two ends of the heat dissipation cavity 23 communicated with the external environment means that the heat dissipation cavity 23 is communicated with the environment outside the charging module 100, for example, the heat dissipation cavity 23 is communicated with a container containing the heat conduction medium or a heat conduction medium generating device. It can be understood that the first charging element 31 and the second charging element 32 mentioned in the embodiment of the present application are used to provide electric energy when the charging module 100 is communicated with other electronic devices. The first charging element 31 and the second charging element 32 can be electronic elements respectively having different functions and independently working, and can also be electronic elements working together, for example, a processor for controlling output voltage, a processor for controlling output current, a sensor for measuring temperature in the first containing cavity 11, a sensor for measuring temperature in the second containing cavity 12, a processor for controlling temperature inside the charging module 100 and the like. At the same time, since the heat dissipation cavity 23 is sealed and isolated from the first containing cavity 11 and the second containing cavity 12, dust and other impurities can be effectively prevented from entering the first containing cavity 11 and / or the second containing cavity 12, so that dust and other impurities are prevented from accumulating on the surface of the electronic elements and modules, thereby affecting the working efficiency and service life. It should be noted that the heat dissipation plate 21 and the cover plate 22 in the embodiment of the present application are made of materials having good heat conduction performance and insulation, or are coated with an insulating coating on one side or both sides of the material having good heat conduction performance.

[0031] It is worth mentioning that the cover plate 22 and the heat dissipation plate 21 are connected by friction stir welding. Friction stir welding refers to the heat generated by the friction between the high-speed rotating welding tool and the cover plate 22 and the heat dissipation plate 21 to locally melt the welded materials. When the welding tool moves forward along the welding interface, the plasticized cover plate 22 and the heat dissipation plate 21 flow from the front to the rear of the welding tool under the rotating friction force of the welding tool, and form a dense solid-phase weld under the extrusion of the welding tool. The advantages of this welding method are: 1. The heat-affected zone of the welded joint has small microstructure change and low residual stress, and the cover plate 22 and the heat dissipation plate 21 after welding are not easy to deform. 2. It can complete long welds, large sections and different positions at one time to adapt to the long welds of the cover plate 22 and the heat dissipation plate 21 in the embodiment. 3. The operation process of friction stir welding is convenient to realize mechanization and automation, and the equipment of friction stir welding is simple, low in energy consumption and high in efficiency, so it is convenient for batch production and improves the production efficiency. 4. No welding medium such as welding wire is needed, and no protective gas is needed, which is safe and low in cost. 5. The welding process is safe, pollution-free, smoke-free and radiation-free.

[0032] Further, please refer to Figures 3-5 , and other drawings. The heat dissipation plate 21 is provided with a first heat dissipation channel 211 and a second heat dissipation channel 212 in communication, and the first heat dissipation channel 211 and the second heat dissipation channel 212 are respectively in communication with the external environment, and the first heat dissipation channel 211 and the second heat dissipation channel 212 are connected together to form a heat dissipation cavity 23, and the first heat dissipation channel 211 and / or the second heat dissipation channel 212 are also provided with a horizontal flow channel 24. It can be understood that, in order to increase the contact area between the heat dissipation cavity 23 and the first receiving cavity 11 and the second receiving cavity 12, the first heat dissipation channel 211 and the second heat dissipation channel 212 are arranged in a continuous "several" character shape on the heat dissipation plate 21, and in other embodiments, they can also be arranged in a continuous "U", "M" or "Z" shape. And the channel aperture at the connection of the first heat dissipation channel 211 and the second heat dissipation channel 212 is smaller than the channel aperture inside the first heat dissipation channel 211 and the second heat dissipation channel 212, so that when the heat conduction medium flows between them, the flow rate of the heat conduction medium can be increased through the design of the small aperture, thereby improving the heat exchange efficiency. In order to better illustrate the relationship between the horizontal flow channel 24 and the first heat dissipation channel 211 and the second heat dissipation channel 212, please refer to Figure 4 and Figure 5 , the bottom of the horizontal flow channel 24 is closer to the heat dissipation plate 21 than the bottom of the first heat dissipation channel 211 and the second heat dissipation channel 212, so that the horizontal flow channel 24 can dissipate heat for the first charging element 31 installed on the surface of the heat dissipation plate 21 and the surface of the cover plate 22, and also can dissipate heat for part of the second charging element 32 abutting against the other surface of the heat dissipation plate 21.

[0033] Furthermore, the heat sink 21 is provided with at least one first heat dissipation portion 213 extending toward the second receiving cavity 12. A first heat dissipation channel 211 is provided on the side of the first heat dissipation portion 213 facing the first receiving cavity 11. The portion of the first heat dissipation portion 213 exposed in the second receiving cavity 12 is used to install the second charging element 32. That is, by protruding the first heat dissipation portion 213 toward the second receiving cavity 12, a larger space can be provided in the first receiving cavity 11 to accommodate more electronic components. At the same time, the cover design of the heat sink 21 and the cover plate 22 makes the plane of the heat sink 21 and the cover plate 22 in the first receiving cavity 11 flatter, thereby facilitating the installation of electronic components and modules such as circuit boards that occupy a large area and require a certain installation space. Correspondingly, since the first heat dissipation portion 213 faces the first receiving cavity 11, it has a larger heat dissipation area in the second receiving cavity 12, and the electronic components can be cooled by mounting them on the surface of the first heat dissipation portion 213 in the second receiving cavity 12.

[0034] Further, please refer to Figure 6 It illustrates one embodiment of the present application. Figure 5 The enlarged view of part B is shown in conjunction with other accompanying drawings. The heat dissipation mechanism 20 also includes a heat sink 25, which is disposed within the first heat dissipation channel 211. The heat sink 25 is mounted at the bottom of the first heat dissipation channel 211 and seals the second receiving cavity 12 of the heat dissipation chamber 23. Furthermore, the heat sink 25 and the first heat dissipation channel 211 seal and isolate the heat dissipation chamber 23 from the second receiving cavity 12. It should be noted that the heat sink 25 is also connected to the bottom of the first heat dissipation channel 211 using friction welding.

[0035] For the heat sink 25 mentioned above, please refer to Figure 5 It illustrates one embodiment of the present application. Figure 4 The enlarged view of part B, in conjunction with other accompanying drawings, shows that the heat sink 25 includes a mounting portion 251, a main body 252, a first fin 253, and a second fin 254. The main body 252 is disposed perpendicular to the mounting portion 251, the first fin 253 is disposed on the main body 252 and perpendicular to the main body 252, and the second fin 254 is disposed on the main body 252 and perpendicular to the first fin 253. It should be noted that the mounting part 251, the main body 252, the first fin 253, and the second fin 254 are all in the shape of a long strip. The mounting part 251 is used to install the heat sink 25 in the first guide groove 12. The main body 252 is vertically arranged on the mounting part 251 and is located in the middle of the mounting part 251, so that the first fin 253 can be symmetrically arranged on both sides of the main body 252. The second fin 254 is arranged perpendicular to the first fin 253. It can be understood that the second fin 254 in this application is located on the side of the first fin 253 away from the mounting part 251.

[0036] Further, the heat dissipation member 25 further comprises a third fin 255, the third fin 255 is arranged on the main body part 252, the third fin 255 is perpendicular to the main body part 252, the third fin 255 is arranged in parallel with the first fin 253, and the width of the third fin 255 is smaller than the width of the first fin 253. It can be understood that the third fin 255 is arranged between the mounting part 251 and the first fin 253, and the width referred to in the present application is the length of the first fin 253, the second fin 254 and the third fin 255 protruding from the main body part 252. Through the above design, the heat dissipation member 25 as a whole presents a "tree-like" bifurcation, and the advantage of this design is that the heat conducting medium can be fully in contact with the heat dissipation member 25, and the first fin 253, the second fin 254 and the third fin 255 increase the contact area of the heat conducting medium with the heat dissipation member 25, facilitating heat exchange. It is worth mentioning that the width and thickness of the first fin 253 and the third fin 255 are smaller than the mounting part 251, the part of the main body part 252 close to the mounting part 251 is wider than the part of the main body part away from the mounting part 251, but since the width of the third fin 255 is smaller than the width of the first fin 253, the third fin 255 in the embodiment of the present application is flush with the first fin 253, and in other embodiments, the relationship between the width of the third fin 255 and the width of the first fin 253 can also be gradually increasing or gradually decreasing. It should be noted that the heat dissipation member 25 uses an aluminum extrusion processing technology, which can manufacture the heat dissipation member 25 with high-density first fin 253, second fin 254 and third fin 255. The high density referred to herein means that the first fin 253, the second fin 254 and the third fin 255 have more quantity in a certain space, thereby increasing the heat exchange area in a limited space to improve the heat exchange efficiency.

[0037] In the embodiment of the present application, please refer to Figures 3-5The heat dissipation plate 21 is provided with at least one second heat dissipation part 214 extending towards the second accommodating cavity 12, and the second heat dissipation channel 212 is arranged on the side of the second heat dissipation part 214 facing the first accommodating cavity 11. The part of the second heat dissipation part 214 exposed to the second accommodating cavity 12 is used for mounting the second charging element 32. That is, the side of the second heat dissipation part 214 facing the second accommodating cavity 12 is protrudingly arranged, so that the first accommodating cavity 11 has more space to accommodate more electronic elements. Meanwhile, the cover of the heat dissipation plate 21 and the cover plate 22 is designed so that the heat dissipation plate 21 and the cover plate 22 are more flat on the plane of the first accommodating cavity 11, thereby facilitating the installation of electronic elements and modules which occupy a larger area and require a certain installation space, such as circuit boards. Correspondingly, since the side of the second heat dissipation part 214 facing the first accommodating cavity 11, the second accommodating cavity 12 has a larger heat dissipation area, and the electronic elements can be installed on the surface of the second heat dissipation part 214 in the second accommodating cavity 12 to dissipate heat for the electronic elements.

[0038] It should be noted that the first heat dissipation part 213 and the second heat dissipation part 214 are further described in combination with the above-mentioned embodiments. First, the first heat dissipation part 213 and the second heat dissipation part 214 extend towards the direction of the second accommodating cavity 12, and a plurality of first heat dissipation parts 213 and second heat dissipation parts 214 are arranged, so that the space in the second accommodating cavity 12 can be divided into an accommodating area enclosed by the shell 10, the heat dissipation plate 21 and the first heat dissipation part 213, another accommodating area enclosed by two first heat dissipation parts 213, the heat dissipation plate 21 and the shell 10, still another accommodating area enclosed by the first heat dissipation part 213, the second heat dissipation part 214, the heat dissipation plate 21 and the shell 10, and again another accommodating area enclosed by two second heat dissipation parts 214, the heat dissipation plate 21 and the shell 10, wherein the horizontal flow channel 24 can also be arranged on the heat dissipation plate 21. That is, the second charging element 32 arranged in the second accommodating cavity 12 can have more surfaces for heat dissipation, thereby improving the heat dissipation efficiency. Specifically, the first charging element 31 has a lower heat generation efficiency than the second charging element 32, and the types of the first charging element 31 need to be integrated on the same circuit board or module, so that the first accommodating cavity 11 with more space is used to accommodate the first charging element 31; and the second charging element 32 with relatively higher heat generation efficiency is arranged in the second accommodating cavity 12, and the contact area is increased by the first heat dissipation part 213 and the second heat dissipation part 214, thereby improving the heat dissipation efficiency. Furthermore, the heat dissipation member 25 arranged in the first heat dissipation part 213 has a "tree" shaped heat dissipation fin composed of the first fin 253, the second fin 254 and the third fin 255, so that the heat dissipation efficiency of the first heat dissipation part 213 is greater than that of the second heat dissipation part 214; the second heat dissipation part 214 includes the first flow channel 2121 and the second flow channel 2122 arranged in a three-dimensional flow channel, and the horizontal flow channel 24 arranged in a horizontal flow channel and communicating the first flow channel 2121 and the second flow channel 2122. Specifically, the heat dissipation efficiency of the first heat dissipation part 213 exposed in the second accommodating cavity 12 is greater than that of the second heat dissipation part 214, so that the part of the second charging element 32 with higher heat generation efficiency can be arranged between the first heat dissipation parts 213, and the part of the second charging element 32 with lower heat generation efficiency can be arranged between the second heat dissipation parts 214. In summary, in the structure provided by the embodiments of the present application, not only the three-dimensional heat dissipation flow channel composed of the first heat dissipation part 213 and the second heat dissipation part 214, but also the horizontal flow channel 24, so that the elements with different heat generation efficiencies in the charging module 30 can be arranged separately in the first accommodating cavity 11 and the second accommodating cavity 12, thereby improving the heat exchange efficiency and the space utilization. Optionally, the width of the first flow channel 2121 is smaller than the width of the second flow channel 2122.

[0039] Further, the second heat dissipation passage 212 comprises a first flow channel 2121 and a second flow channel 2122 which are communicated, the first flow channel 2121 is communicated with the first heat dissipation passage 211, and the second flow channel 2122 is communicated with the external environment, and the second heat dissipation passage 212 is provided with at least one horizontal flow channel 24, two ends of the horizontal flow channel 24 are communicated with the first flow channel 2121 and the second flow channel 2122 respectively. It should be noted that the horizontal flow channel 24 is arranged in a curved manner, which can obtain a larger flow area within a certain length. It should be noted that the flow area described in the embodiments of the present application refers to the area through which the heat conducting medium flows in the horizontal flow channel 24. For the above horizontal flow channel 24, please refer to Figure 3 、 Figure 4 、 Figure 6 and Figure 7 wherein, Figure 7 shows a C part enlarged view of the Figure 5 provided by one of the embodiments of the present application, and in combination with other drawings. The horizontal flow channel 24 is provided with an anti-backflow protrusion 241, which is located at the communication position of the horizontal flow channel 24 and the second flow channel 2122. When the heat conducting medium flows to the connection position of the horizontal flow channel 24 and the second flow channel 2122, it can be separated by the wall surface of the anti-backflow protrusion 241, so that the heat conducting medium in the horizontal flow channel 24 and the second flow channel 2122 has the same flow direction when flowing to the anti-backflow protrusion 241, preventing the heat conducting medium from flowing back from the second flow channel 2122 to the horizontal flow channel 24, facilitating the flow of the heat conducting medium in the heat dissipation cavity 23, and thus improving the heat dissipation efficiency. Optionally, the width of the first flow channel 2121 is smaller than the width of the second flow channel 2122, so that the flow rate of the heat conducting medium in the first flow channel 2121 can be increased to flow into the second flow channel 2122, so as to improve the heat dissipation efficiency.

[0040] In the present application, the first flow channel 2121, the second flow channel 2122 and the at least one horizontal flow channel 24 are arranged on the second heat dissipation passage 212, which can form a three-dimensional flow channel and a horizontal flow channel in this area. For example, in the present application, the three-dimensional flow channel can dissipate heat for the electronic elements in the second accommodating cavity 12, the horizontal flow channel 24 can dissipate heat for the electronic elements arranged in the first accommodating cavity 11 and close to or attached to the cover plate 22, and can dissipate heat for the electronic elements located in the second heat dissipation part 214. By arranging the three-dimensional flow channel and the horizontal flow channel in the second heat dissipation passage 212, the electronic elements can obtain more sufficient layout space and more layout modes, so as to reduce the volume of the entire charging module.

[0041] Furthermore, in this application, the simultaneous provision of the first receiving cavity 11 and the second receiving cavity 12, as well as the provision of the first heat dissipation channel 211, the second heat dissipation channel 212, and the horizontal flow channel 24, allows components with different power outputs, i.e., different sizes, to be configured according to requirements, thereby improving the heat dissipation efficiency of the entire charging module 100.

[0042] For housing 10, please refer to Figures 3-5 The outer casing includes an outer casing body 13, a first sealing plate 14, and a second sealing plate 15. The first sealing plate 14 and the second sealing plate 15 are installed on both sides of the outer casing body 13. The first sealing plate 14, part of the outer casing body 13, the heat sink, and the cover plate together form a first receiving cavity 11. The second sealing plate 15, another part of the outer casing body 13, and the heat sink together form a second receiving cavity 12. Optionally, in this embodiment, a sealing element 16 is also provided. The sealing element 16 is disposed at the edge where the first sealing plate 14 connects to the outer casing body 13, and at the edge where the second sealing plate 15 connects to the outer casing body 13, thereby ensuring good sealing performance at the edge sealing of the outer casing 10.

[0043] This application provides a charging module 100, which includes a housing 10, a heat dissipation mechanism 20, and a charging module 30. The heat dissipation mechanism 20 includes a heat sink 21 and a cover plate 22. The heat sink 21 is installed inside the housing 10, and the cover plate 22 covers the heat sink 21. The cover plate 22 and the heat sink 21 together form a heat dissipation cavity 23. The two ends of the heat dissipation cavity 23 are in communication with the external environment and are used for the flow of a heat-conducting medium. The heat sink 21 seals and isolates the housing 10 into a first receiving cavity 11 and a second receiving cavity 12 located on both sides of the heat sink 21. The charging module 30 includes a first charging element 31 and a second charging element 32, which are respectively disposed on both sides of the heat sink 21. The heat dissipation cavity 23 is used to dissipate heat from the first charging element 31 and the second charging element 32. Through the above design, the heat dissipation cavity 23 is sealed and isolated from the first receiving cavity 11 and the second receiving cavity 12, preventing dust and other impurities in the external environment from entering the first receiving cavity 11 and / or the second receiving cavity 12, and the electronic components are respectively placed in the first receiving cavity 11 and the second receiving cavity 12 for regional heat dissipation, thereby improving the heat exchange efficiency of the charging module 100.
