[0034] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0035] As described in the background section, existing automotive generator controllers connect the water cooler to the generator controller housing to achieve heat dissipation and cooling. However, the water cooler and the generator controller are two independent devices. They exchange heat through contact, which results in a long heat exchange path and poor heat dissipation of the generator controller. Moreover, the space occupied by connecting the two is large, which goes against the current development trend of improving the space utilization of new energy vehicles.

[0036] In view of the above problems, the present invention provides a housing, a generator controller and a vehicle, which can solve the above problems, and will be described in detail below.

[0037] Please refer to Figures 1 to 3The housing 1 has an internal ring of baffles 101, which together form a first flow channel 10. The outer wall of the housing 1 has a second flow channel 11, which is connected to the first flow channel 10. When this housing 1 is applied to a generator controller, the first element 2 can be connected to the first flow channel 10, allowing heat dissipation through the first flow channel 10. The second element 3 can be attached to the inner wall of the housing 1 and correspond to the second flow channel 11, allowing heat dissipation through the second flow channel 11. Arranging the first flow channel 10 and the second flow channel 11 inside and on the outer wall of the housing 1 avoids the need for a separate water cooler, thus reducing the overall size. Furthermore, the heat exchange distance between the first flow channel 10 and the first element 2, and between the second flow channel 11 and the second element 3, is closer, resulting in more efficient heat dissipation for both elements.

[0038] The outer wall of the shell 1 is provided with a flow guiding groove 111 and a flat groove 112. The flow guiding groove 111 and the flat groove 112 are connected. The flow guiding groove 111 is connected to the first flow channel 10. The flow guiding groove 111 and the flat groove 112 together form the second flow channel 11.

[0039] The depth of the flow guide groove 111 is greater than the depth of the flat groove 112, and the width of the flow guide groove 111 is less than the width of the flat groove 112.

[0040] Multiple guide ribs 113 are provided inside the flat groove 112. One end of the multiple guide ribs 113 is close to the guide groove 111, and the other end of the multiple guide ribs 113 extends to the corner area of ​​the flat groove 112.

[0041] The above-mentioned housing 1 is applied to the generator controller, and the generator controller is used as the main body for detailed description.

[0042] The generator controller includes a first element 2, a second element 3, and a housing 1. The first element 2 and the second element 3 are disposed inside the housing 1. The first element 2 is disposed inside the housing 1 and is spaced apart from the inner wall of the housing 1. The second element 3 is attached to the inner wall of the housing 1. A ring of baffles 101 is disposed inside the housing 1. The ring of baffles 101 surrounds and forms a first flow channel 10. The end face of the baffles 101 is sealed and connected to the outer wall of the first element 2. A second flow channel 11 is disposed on the outer wall of the housing 1. The position of the second flow channel 11 corresponds to the position of the second element 3. The second flow channel 11 is connected to the first flow channel 10.

[0043] The first flow channel 10 is connected to the cooling medium, which flows sequentially through the first flow channel 10 and the second flow channel 11. The cooling medium flows sequentially to dissipate heat and cool the first element 2 and the second element 3. In this embodiment of the invention, the flow channels of the cooling medium of the generator controller are arranged inside the housing 1 and on the outer wall, so that the heat dissipation and cooling structure is integrated with the generator controller, avoiding the need for a separate water cooler. Compared with the current use of a separate water cooler for heat exchange, the arrangement of this embodiment can greatly reduce the overall volume of the generator controller, thereby reducing the space occupation rate of the generator controller. When applied to automobiles, it can make the whole vehicle structure more compact, and eliminating the need for a separate water cooler helps to reduce assembly costs and improve the space utilization of the whole vehicle.

[0044] In terms of heat dissipation and cooling, the housing of the existing generator controller is connected to the water cooler. The cooling medium inside the water cooler is separated from the first element 2 and the second element 3 by the water cooler tube wall and the housing 1. The heat transfer path is long and the heat transfer efficiency is low, resulting in poor heat dissipation. In this embodiment, the cooling medium in the first flow channel 10 can directly contact the first element 2, thereby exchanging heat with the first element 2 faster and more efficiently. The second flow channel 11 is separated from the second element 3 only by the housing 1, shortening the heat transfer path and exchanging heat with the second element 3 faster, thereby dissipating heat for the second element 3 more efficiently.

[0045] It should be understood that, in this embodiment, the first element 2 and the second element 3 are heat source devices. Besides the first element 2 and the second element 3, the heat source devices may also include other heat-generating elements. In this embodiment, the first element 2 may be a power module, and the second element 3 may be a thin-film capacitor.

[0046] refer to Figure 5 In this embodiment, the generator controller also includes a bottom cover 4. The housing 1 and the bottom cover 4 are connected together, forming a space inside for installing heat source devices. The housing 1 and the bottom cover 4 can be connected by bolts / screws, welding, or other methods. The housing 1 has an outer top surface and a top side surface. The top side surface surrounds the outer top surface and is in contact with it. A second flow channel 11 is disposed on the outer wall of the housing 1, and the bottom wall of the second flow channel 11 is lower than the outer top surface. The bottom cover 4 has an outer bottom surface and a bottom side surface. The bottom side surface surrounds the outer bottom surface and is in contact with it. When the bottom cover 4 and the housing 1 are connected together, the outer top surface and the outer bottom surface are spaced apart and opposite each other, and the top side surface and the bottom side surface are in contact.

[0047] The inner wall of the bottom cover 4 is provided with multiple connecting posts, and the first element 2 is mounted on the multiple connecting posts and spaced apart from the bottom cover 4. The outer wall of the second element 3 is attached to the inner wall of the housing 1, and the second element 3 and the first element 2 are located in different areas inside the housing 1.

[0048] Multiple baffles 101 are arranged in a ring. One end face of each baffle 101 is sealed to the inner wall of the housing 1, and the other end face of each baffle 101 is sealed to the outer wall of the first element 2. A cooling medium is connected to the first flow channel 10, and the cooling medium can directly contact the first element 2. Of course, the multiple baffles 101 also need to be sealed to each other. For example, waterproof sealant can be used for bonding. Alternatively, the multiple baffles 101 can be integrally molded and then sealed to the inner wall of the housing 1.

[0049] refer to Figure 4 The housing 1 is also provided with a connecting hole 102. The two ends of the connecting hole 102 penetrate the inner and outer walls of the housing 1 respectively. One end of the connecting hole 102 is located in the first flow channel 10, and the other end of the connecting hole 102 is located in the second flow channel 11. The connecting hole 102 connects the first flow channel 10 and the second flow channel 11.

[0050] The second flow channel 11 includes a flow-guiding groove 111 and a flat groove 112, which are connected and together form the second flow channel 11. One end of the connecting hole 102 is located in the flow-guiding groove 111, allowing the cooling medium in the first flow channel 10 to enter the flow-guiding groove 111 through the connecting hole 102 and then flow into the flat groove 112. Since the position of the flat groove 112 corresponds to the position of the second element 3, and the position of the first flow channel 10 corresponds to the position of the first element 2, and the second element 3 and the first element 2 are distributed in different areas within the housing 1, the flow-guiding groove 111 can guide the cooling medium in the first flow channel 10 to the flat groove 112.

[0051] The depth of the guide groove 111 is greater than the depth of the flat groove 112, and the width of the guide groove 111 is less than the width of the flat groove 112. This arrangement allows the cooling medium entering the guide groove 111 to first reach the same height as the bottom wall of the flat groove 112, and then flow into the flat groove 112 at a slower speed. This facilitates the uniform distribution of the cooling medium within the flat groove 112, thereby improving the uniformity of heat dissipation to the second element 3. The flat groove 112 is shallower and wider than the guide groove 111, which increases the heat exchange contact area between the cooling medium and the second element 3, improving heat dissipation efficiency. Furthermore, it allows the entire generator controller to be flatter, reducing the overall height of the generator controller.

[0052] Optionally, a plurality of guide ribs 113 are provided in the flat groove 112. One end of the guide ribs 113 is close to the guide groove 111, and the other end of the guide ribs 113 extends to the corner area of ​​the flat groove 112. The guide ribs 113 guide the cooling medium to the corner area of ​​the flat groove 112, avoiding large differences in the flow rate of the cooling medium in different areas of the flat groove 112, which would affect the uniformity of heat dissipation. It can also prevent the cooling medium from flowing directly from the guide groove 111 to the liquid outlet end of the flat groove 112. The guide ribs 113 divert the cooling medium entering the flat groove 112, which is beneficial to improving the uniformity of heat dissipation of the second element 3 and solving the problem of insufficient local heat dissipation of the second element 3. In this embodiment, there are two guide ribs 113, both of which are arc-shaped. The arc-shaped guide ribs 113 do not reduce the flow velocity of the cooling medium.

[0053] The second element 3 is attached to the inner wall of the housing 1. The contact area between the second element 3 and the inner wall of the housing 1 is included within the range of the second flow channel 11, thereby ensuring that the second element 3 and the cooling medium in the second flow channel 11 have sufficient heat exchange area.

[0054] Of course, since the second flow channel 11 is located on the outer wall of the housing 1, a sealing plate 6 is provided on the upper cover of the second flow channel 11. The sealing plate 6 is sealed to the housing 1 to prevent the cooling medium in the second flow channel 11 from leaking. Figure 4 The sealing method between the sealing plate 6 and the housing 1 can be a sealing gasket, a sealant, or other methods, and there are no limitations on this.

[0055] It is worth mentioning that the housing 1 is provided with a liquid inlet and a liquid outlet. The liquid inlet is connected to a liquid inlet pipe 7, and the liquid outlet is connected to a liquid outlet pipe 8. The liquid inlet pipe 7 is connected to the first flow channel 10, and the liquid outlet pipe 8 is connected to the flat groove 112. The liquid inlet pipe 7 is used to deliver the cooling medium to the first flow channel 10, and the liquid outlet pipe 8 is used to recover the cooling medium after heat exchange.

[0056] In this embodiment, the flow guiding groove 111 is disposed on the side of the flat groove 112. The flow guiding groove 111 and the liquid outlet are located diagonally on both sides of the flat groove 112, thereby allowing the cooling medium to flow obliquely within the flat groove 112.

[0057] Continue to refer to Figure 4 The top side of the housing 1 is also provided with a terminal block 12. The terminal block 12 has a terminal face 121 and a terminal socket 122. One end of the terminal socket 122 passes through the terminal face 121, and the other end of the terminal socket 122 passes through the inner wall of the housing 1. Terminals can be arranged through the terminal socket 122 to facilitate wiring connection.

[0058] Currently, most of the terminal blocks 12 on the housing 1 of existing generator controllers are arranged vertically, that is... Figure 3 The major axis of the terminal block 12, which is approximately elliptical in shape, is along the Z-axis, and the terminal face 121 on the terminal block 12 is parallel to the YZ plane. This arrangement of the terminal block 12 not only occupies a large space, but also makes it impossible to prevent splashing water from entering the terminal socket 122 because the terminal face 121 is parallel to the YZ plane. For example, if the generator controller is placed below the car generator, that is, the housing 1 of the generator controller is connected to the generator and the bottom cover 4 is close to the ground, water splashed from the ground can easily enter the terminal socket 122, which can easily lead to short circuit faults.

[0059] Therefore, in this embodiment, the terminal face 121 of the terminal block 12 is inclined, tilted towards the positive X-axis, so that the terminal face 121 tilts upward to prevent splashing water from entering the terminal socket 122, increasing the safety when the generator controller is located at the bottom of the generator. Furthermore, in this embodiment, the major axis of the elliptical surface of the approximately elliptical terminal block 12 is deflected towards the Y-axis, so that the top of the terminal block 12 does not exceed the outer top surface of the housing 1, and the bottom of the terminal block 12 does not exceed the outer bottom surface of the bottom cover 4, thereby reducing the space occupied by the terminal block 12.

[0060] refer to Figure 5 The bottom surface of the bottom cover 4 is also connected to a wiring sealing cover 5, which is used to cover the wiring part. Since the wiring sealing cover 5 of the existing generator controller is only made of steel and the surface of the wiring sealing cover 5 is not protected, it is easily corroded by water during long-term use, resulting in failure of the sealing protection. Therefore, the surface of the wiring sealing cover 5 in this embodiment is provided with an anti-corrosion layer to improve the corrosion resistance of the wiring sealing cover 5 and extend the service life of the wiring sealing cover 5.

[0061] For example, chrome plating followed by zinc plating on the surface of the wiring sealing cover 5 not only prevents corrosion but also increases the overall strength of the wiring sealing cover 5, improving its protective capability and protection level. Of course, the anti-corrosion layer can also be made of other materials, such as resin materials that meet the requirements or platings of other metal materials; there are no limitations on this.

[0062] The generator controller of the present invention has at least the following beneficial effects:

[0063] (1) The first flow channel 10 and the second flow channel 11 are respectively set inside the shell 1 and on the outer wall, so that the heat dissipation and cooling facilities are integrated with the generator controller. Compared with setting a separate water cooler, it not only improves the heat dissipation effect, but also reduces the overall volume of the generator controller, which is conducive to improving the overall space utilization of the car and provides conditions for the inverted arrangement of the generator controller.

[0064] (2) The first flow channel 10 is connected to the first element 2, which allows the cooling medium to directly contact the first element 2, resulting in good heat dissipation. The second flow channel 11 is divided into a flow guide groove 111 and a flat groove 112 with sufficient heat exchange area. Moreover, the flat groove 112 is provided with flow guide ribs 113, which can increase the uniformity of heat dissipation and improve the heat dissipation effect while ensuring the heat exchange area.

[0065] (3) Adjust the orientation of the terminal block 12 to reduce the space occupied by the terminal block 12, and at the same time tilt the terminal face 121 to avoid water splashed from the ground from entering the terminal socket 122, thereby improving safety and providing technical support for the generator controller to be placed under the generator.

[0066] (4) The surface of the wiring sealing cover 5 is provided with an anti-corrosion layer, which extends the service life of the wiring sealing cover 5 and provides technical support for the inverted arrangement of the generator controller.

[0067] An embodiment of this utility model also provides a vehicle, including a generator and the generator controller. The generator controller is connected to the generator and can be located on the upper part or the lower part of the generator. When the generator controller is located on the lower part of the generator, the housing 1 of the generator controller is in contact with the bottom wall of the generator. At this time, the bottom cover 4 of the generator controller is close to the ground, and the wiring terminal face 121 is inclined upward.

[0068] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
