Abstract
Description
Technical Field
[0001] This utility model relates to the field of electronic speed controller technology, and in particular to a high-power electronic speed controller for unmanned aerial vehicles (UAVs). Background Technology
[0002] An electronic speed controller (ESC) is an electronic device that adjusts the output speed and torque of a motor based on external control signals. It is widely used in scenarios requiring precise control of motor operation, such as drones, robots, and electric models. It typically has protective functions, automatically cutting off the output in case of motor overload, short circuit, overvoltage, or overcurrent to prevent damage to the motor and related equipment, ensuring safe and stable system operation.
[0003] Existing electronic speed controllers typically use self-heating to dissipate heat from internal electrical components. However, this method is inefficient in high-power output scenarios. In particular, when drones operate under high loads for extended periods, internal heat is difficult to dissipate quickly, causing a sudden rise in the temperature of core components. This can lead to the risk of thermal runaway. Furthermore, high temperatures can accelerate component aging and shorten the lifespan of internal components. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a high-power electronic speed controller for unmanned aerial vehicles (UAVs).
[0005] This utility model is achieved using the following technical solution: a high-power electronic speed controller for drones, comprising a housing, a main control board fixedly connected to the bottom of the inner wall of the housing, an MCU processing chip fixedly connected to the top of the main control board, silicone being disposed in contact with the top of the MCU processing chip, fins being disposed in contact with the top of the silicone, a connecting block being fixedly connected to the bottom of the fins, a screw being threadedly connected inside the connecting block, the screw being threadedly connected inside the main control board, and a cooling fan being disposed in contact with the top of the fins.
[0006] Through the above technical solution, the outer casing protects the internal electrical components. When the MCU processing chip generates heat during operation, the heat is transferred to the fins through the silicone on the top. The silicone fills the gap between the MCU processing chip and the fins, improving heat conduction efficiency. At this time, the cooling fan rapidly reduces the temperature of the fins, allowing them to absorb more heat and thus quickly cooling the MCU processing chip. This also reduces the overall temperature inside the casing, thereby reducing the risk of thermal runaway and improving the stability of the equipment. The cooling fan ensures that the MCU processing chip can operate stably, extending the lifespan of the electrical components. The fins are fixed to the main control board by connecting blocks and screws, ensuring stable contact. The fins can be cleaned by removing the screws.
[0007] As a further improvement to the above solution, a guide groove is provided on the inner wall of the outer shell, and a guide plate is slidably connected to the outer wall of the guide groove.
[0008] As a further improvement to the above solution, the guide plate is fixedly connected to the outer wall of the cooling fan, and a fixing block is fixedly connected to the outer wall of the cooling fan.
[0009] As a further improvement to the above solution, a first screw is slidably connected to the inner wall of the fixing block, and the first screw is threadedly connected to an internal stud, which is fixedly connected to the bottom of the inner wall of the outer shell.
[0010] With the above technical solution, the cooling fan is slidably positioned along the guide groove on the inner wall of the outer casing by the guide plate and fixed by the fixing block, the first screw and the internal stud. The guide plate facilitates quick positioning and installation by personnel, while the first screw allows the cooling fan to be disassembled for easy maintenance and repair.
[0011] As a further improvement to the above solution, a data cable is fixedly connected to the top of the main control board, and a power conversion circuit board is fixedly connected to the top of the main control board.
[0012] As a further improvement to the above solution, a capacitor is fixedly connected to the top of the main control board, an NTC thermistor is fixedly connected to the top of the main control board, and a TVS diode is fixedly connected to the top of the main control board.
[0013] As a further improvement to the above solution, a second screw is threaded inside the outer shell, a cover plate is slidably connected to the outer wall of the second screw, and a heat dissipation and dustproof plate is fixedly connected to the inner wall of the cover plate.
[0014] With the above technical solution, the outer casing is connected to the cover plate by the second screw, and the cover plate is embedded with a heat dissipation and dustproof plate, which ensures heat dissipation while preventing dust from entering the interior and extending the life of the components.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] This invention protects the internal electrical components through a casing. When the MCU processing chip generates heat during operation, the heat is transferred to the fins through silicone on the top. The silicone fills the gap between the MCU processing chip and the fins, improving heat conduction efficiency. At this time, the cooling fan rapidly reduces the temperature of the fins, allowing them to absorb more heat and thus quickly cooling the MCU processing chip. This also lowers the overall temperature inside the casing, reducing the risk of thermal runaway and improving the stability of the equipment. The cooling fan ensures stable operation of the MCU processing chip, extending the lifespan of the electrical components. The fins are fixed to the main control board by connecting blocks and screws, ensuring stable contact. The fins can be cleaned by removing the screws.
[0017] This utility model uses a cooling fan that slides along a guide groove on the inner wall of the outer casing via a guide plate and is fixed by a fixing block, a first screw, and an internal stud. The guide plate allows for quick and easy positioning and installation, while the first screw allows for disassembly of the cooling fan for easy maintenance and repair. Attached Figure Description

[0034] The implementation principle of a high-power electronic speed controller for a drone in this embodiment is as follows: The outer shell 1 protects the internal electrical components. When the MCU processing chip 3 generates heat during operation, the heat is transferred to the fins 5 through the silicone 4 in contact with the top. The silicone 4 fills the gap between the MCU processing chip 3 and the fins 5, improving heat conduction efficiency. At this time, the cooling fan 8 rapidly reduces the temperature of the fins 5, allowing the fins 5 to absorb more heat, thereby rapidly cooling the MCU processing chip 3 and reducing the overall temperature inside the outer shell 1. This reduces the risk of thermal runaway and improves the stability of the device. The cooling fan 8 ensures that the MCU processing chip 3 can operate stably, improving the service life of the electrical components. The fins 5 are fixed to the main control board 2 by the connecting block 6 and screws 7, ensuring stable contact. The fins can be removed by unscrewing the screws 7. 5. Dust removal is performed. The cooling fan 8 is slidably positioned along the guide groove 9 on the inner wall of the outer casing 1 via the guide plate 10 and is fixed by the fixing block 11, the first screw 12 and the internal stud 13. The guide plate 10 facilitates quick positioning and installation by personnel. At the same time, the cooling fan 8 can be disassembled by the first screw 12 for easy maintenance and repair. The main control board 2, as the core control unit, communicates with external devices via the data cable 14 and receives control signals. The power conversion circuit board 15 is responsible for converting DC power into three-phase AC power to drive the motor. The capacitor 16 is used for filtering and voltage regulation. The NTC thermistor 17 monitors the temperature in real time. The TVS diode 18 protects the circuit from voltage spikes. The outer casing 1 is connected to the cover plate 20 via the second screw 19. The cover plate 20 has an embedded heat dissipation and dustproof plate 21, which ensures heat dissipation while preventing dust from entering the interior and extending the life of components.
