Description

Technical Field

[0001] This utility model relates to the field of electric vehicle heat dissipation technology, and in particular to a special toothed radiator for electric vehicle motor controllers. Background Technology

[0002] The electric vehicle motor controller-specific finned heat sink is a high-efficiency heat dissipation solution designed for high power density scenarios. Its core advantage lies in processing a whole metal substrate (such as aluminum and copper) into a high-density fin structure through a precision finned process, achieving an integrated heat dissipation design without connection points.

[0003] In existing technologies, finned radiators use high-precision CNC equipment to directly cut and bend aluminum and copper plates into fins, forming a complete heat conduction path with the base. This process avoids the contact thermal resistance of traditional insert and welding processes, and improves heat dissipation efficiency compared to traditional radiators. Although copper-based radiators have a high thermal conductivity, they are heavier than aluminum-based radiators, affecting vehicle energy efficiency. A hollow mesh structure is used in non-load-bearing areas, combined with topology optimization algorithms, to reduce the weight of the radiator. However, the integrated design requires complete disassembly for replacement, which limits its adaptability to installation in complex spaces and makes installation inconvenient. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a special toothed radiator for electric vehicle motor controllers, which aims to improve the problem that the integrated design in the prior art requires complete disassembly for replacement, which limits its installation adaptability in complex spaces and causes inconvenience in installation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a special toothed radiator for electric vehicle motor controllers, comprising a fixing plate, a base plate mounted on the top of the fixing plate, multiple mounting slots equally spaced on the left and right sides of the outer wall of the base plate, multiple fixing mechanisms equally spaced on the top wall of the fixing plate, the fixing mechanisms being used to fix the base plate, and vibration damping mechanisms equally spaced on the front and rear sides of the top wall of the base plate, the vibration damping mechanisms being used to reduce the vibration impact on the equipment; the fixing mechanism includes a housing, the housing being equidistantly fixedly connected to the front and rear sides of the top wall of the fixing plate, bolts being threadedly connected to the top wall of the housing, a locking block being slidably connected to the inner wall of the housing, the locking block being slidably connected to the inner wall of the mounting slot, a fixing seat being fixedly connected to the front side of the outer wall of the housing, and a limit component being installed on the inner wall of the fixing seat.

[0006] As a further description of the above technical solution: The limiting component includes a pull rod, which is slidably connected to the inner wall of the fixed base. A limiting rod is fixedly connected to the middle of the outer wall of the pull rod. A spring is installed on the outer wall of the pull rod. Fixed rods are fixedly connected to the left and right sides of the top wall of the fixed base.

[0007] As a further description of the above technical solution: The end of the pull rod is rotatably connected to a slider, which is slidably connected to the inner wall of the housing and the outer wall of the locking block.

[0008] As a further description of the above technical solution: The vibration damping mechanism includes a fixing block, which is equidistantly fixed to the front and rear sides of the top wall of the substrate, and a telescopic rod is installed on the front side of the inner wall of the fixing block.

[0009] As a further description of the above technical solution: The top end of the telescopic rod is fixedly connected to a protrusion, and the inner wall of the fixed block is slidably connected to a sliding rod.

[0010] As a further description of the above technical solution: A second spring is installed on the outer wall of the slide rod, and a roller is installed at the end of the slide rod.

[0011] As a further description of the above technical solution: The top wall of the substrate is fixedly connected to a shovel-tooth fin, and a heat pipe is installed on the inner wall of the shovel-tooth fin.

[0012] As a further description of the above technical solution: The outer wall of the shovel-tooth fin is equipped with an interface, which is installed at equal intervals on the front side of the outer wall of the shovel-tooth fin.

[0013] This utility model has the following beneficial effects: 1. In this utility model, pulling the pull rod outward causes the limiting rod on the outer wall to slide outward. Then, rotating the pull rod causes the limiting rod to be locked in the groove of the fixing rod. Then, the locking block is inserted into the outer shell, and the end of the locking block slides into the mounting groove. Then, rotating the pull rod in the opposite direction causes the spring to rebound and push out the limiting rod, allowing the slider to slide into the outer shell and lock the outer wall of the locking block, forming a stable connection. Finally, the bolt is screwed in, and the bolt passes through the outer shell and the locking block to prevent loosening. The operation is convenient and easy to install and disassemble.

[0014] 2. In this utility model, when the shovel tooth fin shakes, it compresses the sliding rods on the front and rear sides. The sliding rods pull the second spring, and the second spring undergoes elastic deformation when it is vibrated. Then, the roller slides along the outer surface of the protrusion, and the protrusion slides along the outer wall of the fixed block to compress the telescopic rod. The telescopic rod undergoes elastic deformation, which absorbs and buffers vibration energy, further improving the vibration resistance of the equipment, avoiding loosening, wear or even damage of parts due to long-term vibration, and extending the service life of the equipment.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of a special toothed radiator for electric vehicle motor controllers, comprising a fixing plate 1, a base plate 2 mounted on the top of the fixing plate 1, multiple mounting grooves 8 evenly spaced on the left and right sides of the outer wall of the base plate 2, multiple fixing mechanisms 3 evenly spaced on the top wall of the fixing plate 1 for fixing the base plate 2, and vibration damping mechanisms 4 evenly spaced on the front and rear sides of the top wall of the base plate 2 for reducing the impact of vibration on the equipment; the fixing mechanism 3 includes a housing 306, which is equidistantly fixed to the front and rear sides of the top wall of the fixing plate 1, bolts 301 are threadedly connected to the top wall of the housing 306, and locking blocks 305 are slidably connected to the inner wall of the housing 306. The locking block 305 is slidably connected to the inner wall of the mounting groove 8. A fixing seat 303 is fixedly connected to the front side of the outer wall of the outer shell 306. A limiting component 304 is installed on the inner wall of the fixing seat 303. The limiting component 304 includes a pull rod 3044, which is slidably connected to the inner wall of the fixing seat 303. A limiting rod 3041 is fixedly connected to the middle of the outer wall of the pull rod 3044. A spring 3042 is installed on the outer wall of the pull rod 3044. Fixing rods 3043 are fixedly connected to the left and right sides of the top wall of the fixing seat 303. A slider 302 is rotatably connected to the end of the pull rod 3044. The slider 302 is slidably connected to the inner wall of the outer shell 306 and the outer wall of the locking block 305. Specifically, place the substrate 2 at the top center of the fixing plate 1, align the mounting grooves 8 on both sides of the substrate 2 with the outer shell 306, and then pull the pull rod 3044 outward. The pull rod 3044 drives the limiting rod 3041 on the outer wall to slide outward. While sliding, the limiting rod 3041 will compress the spring 3042. Then rotate the pull rod 3044 so that the limiting rod 3041 is locked in the groove of the fixing rod 3043. Then insert the locking block 305 into the outer shell 306 and let the end of the locking block 305 slide into the mounting groove 8. Then rotate the pull rod 3044 in the opposite direction. The spring 3042 rebounds and pushes out the limiting rod 3041, so that the slider 302 slides into the outer shell 306 and locks the outer wall of the locking block 305, forming a stable connection. Finally, screw in the bolt 301. The bolt 301 passes through the outer shell 306 and the locking block 305 to prevent loosening. The operation is convenient and easy to install and disassemble.

[0019] Reference Figure 1 , Figure 2 and Figure 5 The vibration damping mechanism 4 includes a fixing block 406, which is fixedly connected at equal intervals to the front and rear sides of the top wall of the base plate 2. A telescopic rod 402 is installed on the front side of the inner wall of the fixing block 406. A protrusion 401 is fixedly connected to the top end of the telescopic rod 402. A slide rod 405 is slidably connected to the inner wall of the fixing block 406. A spring 404 is installed on the outer wall of the slide rod 405. A roller 403 is installed at the end of the slide rod 405. Specifically, when the shovel-tooth fin 5 shakes, it compresses the sliding rods 405 on the front and rear sides. The sliding rods 405 slide and pull the second spring 404. When the second spring 404 is vibrated, it undergoes elastic deformation. Then, the roller 403 slides along the outer surface of the protrusion 401, and the protrusion 401 slides along the outer wall of the fixed block 406 to compress the telescopic rod 402. The telescopic rod 402 undergoes elastic deformation, absorbing and buffering vibration energy, further improving the vibration resistance of the equipment, avoiding loosening, wear or even damage of parts due to long-term vibration, and extending the service life of the equipment.

[0020] Reference Figure 1 , Figure 2 and Figure 3 The top wall of the substrate 2 is fixedly connected to a shovel-tooth fin 5, a heat pipe 6 is installed on the inner wall of the shovel-tooth fin 5, and an interface 7 is installed on the outer wall of the shovel-tooth fin 5. The interfaces 7 are installed at equal intervals on the front side of the outer wall of the shovel-tooth fin 5. Specifically, the toothed fins 5 are formed by cutting from the top of the substrate 2 using a CNC toothing machine to create dense vertical heat dissipation fins, which reduces wind resistance and improves airflow turbulence efficiency. The heat pipe 6 is an annular pulsating pipe that quickly transfers heat to the end of the toothed fins 5 through an evaporation-condensation cycle. The interface 7 is used to connect the sensor and the temperature control element to achieve dynamic heat dissipation.

[0021] Working principle: First, carefully place the substrate 2 at the top center of the fixing plate 1, ensuring that the mounting slots 8 on both sides of the substrate 2 are fully aligned with the corresponding positions of the outer casing 306. Next, pull the pull rod 3044 outward. When the pull rod 3044 is pulled, it will cause the limiting rod 3041 on the outer wall to slide outward. During this sliding process, the limiting rod 3041 will apply pressure, compressing the spring 3042. Subsequently, the operator needs to rotate the pull rod 3044 to ensure that the limiting rod 3041 can smoothly engage with the fixing rod 3043. Inside the groove, insert the locking block 305 into the corresponding position of the outer shell 306, and ensure that the end of the locking block 305 slides into the mounting groove 8. Then, rotate the pull rod 3044 in the opposite direction, and the spring 3042 will rebound, thereby pushing out the limit rod 3041. In this way, the slider 302 will slide into the outer shell 306 and lock the outer wall of the locking block 305, forming a stable connection. Finally, screw in the bolt 301, ensuring that the bolt 301 passes through the outer shell 306 and the locking block 305 to prevent loosening. The entire installation process is convenient to operate and easy to install and disassemble. In another part of the equipment, the shovel-tooth fin 5 compresses the front and rear sliding rods 405 when it shakes. During the sliding process, the sliding rods 405 pull the spring 404, causing it to undergo elastic deformation. The roller 403 slides along the outer surface of the protrusion 401, which in turn causes the protrusion 401 to slide along the outer wall of the fixed block 406 and compress the telescopic rod 402. The telescopic rod 402 also undergoes elastic deformation when subjected to pressure, thereby absorbing and buffering vibration energy. This design can further improve the vibration resistance of the equipment, avoid loosening, wear or even damage of parts due to long-term vibration, and thus extend the service life of the equipment.

[0022] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
