Description

Technical Field

[0001] This utility model relates to the field of driver technology, specifically to a drone driver with dual cooling heat dissipation effect. Background Technology

[0002] As a core component of the drone's power system, the drone driver integrates key components such as the motor, electronic speed controller, and power battery. These components continuously generate heat during drone flight. To ensure structural compactness and protection, the internal space of the driver casing is typically relatively sealed. If heat cannot be dissipated in time, the internal temperature of the casing can rise continuously, affecting the motor's operational stability, the electronic speed controller's control accuracy, and shortening the power battery's flight time. In severe cases, it can even lead to motor winding burnout and short circuits in electronic components. Therefore, heat dissipation performance is a core factor determining the reliability and lifespan of the drone driver. Currently, industry-standard heat dissipation designs for drone drivers often employ methods such as creating ventilation holes on the casing surface, installing built-in cooling fans, or attaching heat-conducting fins to the heat source surface to improve heat dissipation efficiency while maintaining structural compactness.

[0003] Existing drone driver cooling structures still have significant shortcomings, failing to meet the demands for efficient heat dissipation. Firstly, the heat-conducting fins used in current technologies are mostly single-planar structures, only able to conduct heat on localized surfaces of the motor or electronic speed controller. They cannot actively lift heat from the bottom of the driver to the upper part of the casing, leading to continuous heat accumulation at the bottom and the formation of localized high-temperature zones. Secondly, existing cooling structures lack corresponding airflow guidance mechanisms to address the bottom heat accumulation problem. When the top cooling fan operates, it can only draw in a small amount of cool air from the periphery or top of the casing. This cool air cannot flow precisely to the bottom heat accumulation area and cannot fully mix with the hot air conducted by the planar fins. This creates a significant thermal barrier between the planar fins and the top fan, resulting in insufficient heat exchange and ultimately low overall heat exchange efficiency of the driver. This fails to effectively solve the bottom heat accumulation problem and cannot meet the cooling requirements of drones during long-duration flights. Therefore, a drone driver with dual-cooling cooling is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a drone driver with dual cooling effects, thereby solving the technical problem that the heat at the bottom of the driver cannot be actively lifted to the upper part of the housing, resulting in continuous heat accumulation at the bottom of the driver.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a drone driver with dual cooling heat dissipation effect, comprising:

[0006] The outer shell and a protective top plate disposed on the upper surface of the outer shell, wherein the inner cavity of the protective top plate is provided with heat dissipation holes. The heat dissipation holes are designed in a cross shape, and a dust filter plate and a cooling fan are respectively installed in the inner cavity of the air outlet end of the heat dissipation holes. The air outlet end of the heat dissipation holes extends outward through the inner wall of the outer shell, and the air inlet end of the heat dissipation holes is connected to the central air outlet end on the upper surface of the protective top plate.

[0007] The motor is located at the center of the bottom of the inner cavity of the outer shell, and a power battery is installed around the bottom of the inner cavity of the outer shell. An electronic speed controller is installed at the corresponding position at the bottom of the inner cavity of the outer shell. The motor, the electronic speed controller and the power battery are connected by a line. A rotating shaft is rotatably connected around the outer side of the outer shell, and a transmission component is connected between the inner end of the rotating shaft and the rotating end of the motor.

[0008] L-shaped heat-conducting fins are arranged around the center of the bottom of the inner cavity of the outer shell, with the long side of the L-shaped heat-conducting fins extending to the middle of the inner cavity of the outer shell. The short side of the L-shaped heat-conducting fins is in close contact with the motor and the power battery. A guide groove is provided at the bottom of the inner cavity of the outer shell, and the guide groove radiates from the center of the bottom of the inner cavity of the outer shell to the surrounding area. A dustproof net is installed at the air inlet end of the guide groove.

[0009] When the drone driver is running, the motor and power battery generate heat. The short side of the L-shaped heat-conducting fins is in close contact with the motor and power battery, directly conducting the heat generated by them. At the same time, the long side of the L-shaped heat-conducting fins extends into the middle of the inner cavity of the outer shell, raising the conducted heat from the heat source at the bottom of the inner cavity of the outer shell to the upper middle part of the inner cavity of the shell, preventing heat from accumulating at the bottom of the inner cavity of the outer shell.

[0010] When the cooling fan is turned on, external cold air enters through the air inlet end of the guide channel at the bottom of the inner cavity of the outer shell. Before entering, it passes through the dust filter installed at the air inlet end of the guide channel. The filtered cold air flows to the motor in the center of the inner cavity of the outer shell under the guidance of the guide channel. After the cold air is fully mixed with the hot air in the upper part of the inner cavity of the outer shell conducted by the L-shaped heat-conducting fins, it enters through the air inlet end of the heat dissipation hole, and then exits the outer shell through the air outlet end of the heat dissipation hole, forming a convection channel with bottom inlet and top outlet.

[0011] Preferably, the long side of the L-shaped heat-conducting fin has uniformly distributed perforated holes, and the upper surface of the long side and both sides of the short side of the L-shaped heat-conducting fin have a serrated edge design. The perforated holes reduce the weight of the L-shaped heat-conducting fin and lower the equipment load without affecting the heat conduction function; the serrated edges effectively increase the heat dissipation area and improve heat release efficiency; and this design does not change the core shape of the L-shaped heat-conducting fin, allowing it to work in conjunction with the equipment's existing active air-cooling structure to form a bottom-heating, top-dissipating convection heat dissipation path, improving the overall heat dissipation effect.

[0012] Preferably, an elastic thermal pad is added to the front of the short side of the L-shaped heat-conducting fin, and the elastic thermal pad is bonded to the front of the short side of the L-shaped heat-conducting fin. This solves the problem of insufficient heat conduction caused by the hard contact between the original L-shaped heat-conducting fin and the heat source, and improves heat conduction efficiency by filling the gaps; the adhesive connection is simple to operate, requires no additional fixing parts, and does not increase assembly complexity; the elastic thermal pad does not change the core structure and function of the L-shaped heat-conducting fin, and can work in conjunction with serrated edges and hollow holes to further improve heat dissipation performance.

[0013] Preferably, the L-shaped heat-conducting fins have semi-circular grooves on both sides of the center of the short side upper surface, and semi-cylinders are installed around the center of the bottom of the inner cavity of the outer shell, with the positional relationship and shape of the semi-circular grooves and semi-cylinders corresponding. This enables rapid initial positioning of the L-shaped heat-conducting fins within the outer shell, significantly improving installation efficiency; it avoids positional deviations during installation of the L-shaped heat-conducting fins, ensuring their precise contact with the heat source and guaranteeing efficient heat conduction; the structure is simple, requiring only the machining of semi-circular grooves and the installation of semi-cylinders, eliminating the need for complex components and facilitating mass production.

[0014] Preferably, the semi-cylinder is inserted into the corresponding semi-circular groove, and a rotating hole is formed on the upper surface edge of the semi-cylinder, with a rotating shaft rotatably connected to the inner cavity of the rotating hole. This insertion connection improves the reliability of the connection between the L-shaped heat-conducting fins and the outer casing, preventing the fins from loosening during equipment operation. The rotating structure allows the L-shaped heat-conducting fins to have adjustable angles, adapting to different heat source installation scenarios and improving the applicability and heat dissipation flexibility. The overall structure is simple, the assembly steps are convenient, and no complex processing technology is required.

[0015] Preferably, a semi-circular retaining block is added to the upper surface of the semi-cylinder, and the top end of the rotating shaft is connected to the lower edge of the semi-circular retaining block. The lower surface of the semi-circular retaining block rotates and fits into contact with the upper surface of the short side of the L-shaped heat-conducting fin. The semi-circular retaining block effectively prevents the L-shaped heat-conducting fin from vertically shifting, improving the stability of the fin installation. While ensuring the rotation function, the rotational contact between the semi-circular retaining block and the fin further ensures the stability of the heat conduction path. The structure is compact, and the added semi-circular retaining block does not change the core function of the original component, making it easy to integrate with the semi-cylinder and rotating shaft.

[0016] Compared with the prior art, this utility model provides a drone driver with dual cooling heat dissipation effect, which has the following beneficial effects:

[0017] This drone driver features dual-cooling technology. It achieves passive cooling through L-shaped heat-conducting fins, lifting the heat from the main heat source at the bottom and preventing heat accumulation at the bottom of the driver. At the same time, it works in conjunction with bottom airflow channels and top cross-shaped heat dissipation holes and a cooling fan to form active cooling. When the top fan draws air, the external cool air is fully mixed with the hot air conducted by the L-shaped fins through the airflow channels, and then discharged from the top heat dissipation holes, forming a three-dimensional convection channel that enters from the bottom and exits from the top. This effectively solves the thermal barrier problem between the existing planar fins and the top fan, improves the overall heat exchange efficiency, achieves efficient dual-cooling, and solves the problems of heat accumulation and thermal barrier at the bottom.

[0025] 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.

[0026] This utility model provides a technical solution: a drone driver with dual cooling heat dissipation effect, comprising: (see details) Figure 1 , Figure 2 , Figure 3 , Figure 4 . Figure 5 and Figure 6 The outer shell 1 and the protective top plate 2 disposed on the upper surface of the outer shell 1 are provided with heat dissipation holes 3 in the inner cavity of the protective top plate 2. The heat dissipation holes 3 are designed in a cross shape. A dust filter plate 4 and a cooling fan 6 are respectively installed in the inner cavity of the air outlet end of the heat dissipation holes 3. The air outlet end of the heat dissipation holes 3 extends outward through the inner wall of the outer shell 1. The air inlet end of the heat dissipation holes 3 is connected to the center air outlet end on the upper surface of the protective top plate 2.

[0027] The motor 7 is located at the center of the bottom of the inner cavity of the outer shell 1, and the power battery 9 is installed around the bottom of the inner cavity of the outer shell 1. An electronic speed controller 8 is installed at the corresponding position at the bottom of the inner cavity of the outer shell 1. The motor 7, the electronic speed controller 8 and the power battery 9 are connected by a line. A rotating shaft 5 is rotatably connected around the outer side of the outer shell 1, and a transmission component is connected between the inner end of the rotating shaft 5 and the rotating end of the motor 7.

[0028] L-shaped heat-conducting fins 10 are disposed around the center of the bottom of the inner cavity of the outer shell 1, with the long side of the L-shaped heat-conducting fins 10 extending to the middle of the inner cavity of the outer shell 1, and the short side of the L-shaped heat-conducting fins 10 closely attached to the motor 7 and the power battery 9. A guide groove 17 is provided at the bottom of the inner cavity of the outer shell 1, and the guide groove 17 radiates from the center of the bottom of the inner cavity of the outer shell 1 to the surrounding area. A dustproof net 18 is installed at the air inlet end of the guide groove 17.

[0029] When the drone driver is running, the motor 7 and the power battery 9 generate heat. The short side of the L-shaped heat-conducting fin 10 is in close contact with the motor 7 and the power battery 9, directly conducting the heat generated by them. At the same time, the long side of the L-shaped heat-conducting fin 10 extends into the middle of the inner cavity of the outer shell 1, raising the conducted heat from the heat source at the bottom of the inner cavity of the outer shell 1 to the upper middle part of the inner cavity, thus preventing heat from accumulating at the bottom of the inner cavity of the outer shell 1.

[0030] When the cooling fan 6 is turned on, external cold air enters through the air inlet of the guide channel 17 at the bottom of the inner cavity of the outer shell 1. Before entering, it is filtered by the dust filter 18 installed at the air inlet of the guide channel 17. The filtered cold air flows to the motor 7 in the center of the inner cavity of the outer shell 1 under the guidance of the guide channel 17. After the cold air is fully mixed with the hot air in the upper part of the inner cavity of the shell by the L-shaped heat conduction fins 10, it carries heat and enters through the air inlet of the heat dissipation hole 3, and then exits the outer shell 1 through the air outlet of the heat dissipation hole 3, forming a convection channel with bottom inlet and top outlet.

[0031] The L-shaped heat-conducting fins 10, through the design of "raising the heat dissipation height", break through the limitations of traditional single planar heat-conducting fins, effectively solve the problem of thermal barrier between the heat source at the bottom of the inner cavity of the outer shell 1 and the top cooling fan 6, and avoid heat accumulation at the bottom; the airflow channel 17 guides the cold air and hot air to mix more evenly, and at the same time, it works with the cooling fan 6 and the heat dissipation hole 3 to form a stable bottom-in and top-out convection channel, which greatly improves the heat dissipation efficiency.

[0032] Please see Figure 4 The L-shaped heat-conducting fin 10 has evenly spaced perforations 11 on its long side front, and the upper surface of the long side and both sides of the short side of the L-shaped heat-conducting fin 10 are designed with serrated edges 12. The L-shaped heat-conducting fin 10 plays a core role in conducting heat from the heat source to its own long and short sides; the perforations 11 on the long side front allow airflow inside the outer shell 1 to pass through the fin, avoiding the local airflow dead zones that are easily formed by solid fins; the serrated edges 12 on the upper surface of the long side and both sides of the short side increase the contact area with air compared to flat edges, accelerating the release of heat to the air; the perforations 11 reduce the weight of the L-shaped heat-conducting fin 10 without affecting the heat conduction function, thus reducing the equipment load; the serrated edges 12 effectively increase the heat dissipation area and improve heat release efficiency; and this design does not change the core shape of the L-shaped heat-conducting fin 10, and can work in conjunction with the original active air-cooling structure of the equipment to form a bottom-heating and top-dissipating convection heat dissipation path, improving the overall heat dissipation effect.

[0033] An elastic thermal pad 13 is added to the front of the short side of the L-shaped thermal fin 10, and the elastic thermal pad 13 is bonded to the front of the short side of the L-shaped thermal fin 10. The elastic thermal pad 13 has both elasticity and thermal conductivity. Its elasticity can fill the tiny gap between the short side of the L-shaped thermal fin 10 and the heat source, preventing air in the gap from forming a heat insulation layer that hinders heat conduction. At the same time, the elastic thermal pad 13 can stably conduct heat from the heat source to the L-shaped thermal fin 10. The bonding method ensures that there is no relative displacement between the elastic thermal pad 13 and the L-shaped thermal fin 10, ensuring a stable and continuous heat conduction path. It solves the problem of insufficient heat conduction caused by the hard contact between the original L-shaped thermal fin 10 and the heat source, and improves the heat conduction efficiency by filling the gap. The bonding connection is simple to operate, requires no additional fixing parts, and does not increase the assembly complexity. The elastic thermal pad 13 does not change the core structure and function of the L-shaped thermal fin 10, and can work in conjunction with the serrated edge 12 and the hollow hole 11 to further improve the heat dissipation performance.

[0034] Please see Figure 5 and Figure 6The L-shaped heat-conducting fin 10 has semi-circular grooves 14 on both sides of the center of the upper surface of its short side, and semi-cylinders 15 are installed around the center of the bottom of the inner cavity of the outer shell 1. The positional relationship and shape of the semi-circular grooves 14 and semi-cylinders 15 correspond. The correspondence between the positional relationship and shape of the semi-circular grooves 14 and semi-cylinders 15 can limit the horizontal displacement of the L-shaped heat-conducting fin 10 in the inner cavity of the outer shell 1, achieving initial positioning. This positioning does not affect the contact between the short side of the L-shaped heat-conducting fin and the heat source, and at the same time provides a stable foundation for further fixing, ensuring that the L-shaped heat-conducting fin 10 can stably conduct heat from the heat source. It realizes the rapid initial positioning of the L-shaped heat-conducting fin 10 in the outer shell 1, greatly improving the installation efficiency. It avoids positional deviations of the L-shaped heat-conducting fin 10 during installation, ensures its fitting accuracy with the heat source, and provides a guarantee for efficient heat conduction. The structure is simple, requiring only the machining of the semi-circular grooves 14 and the installation of the semi-cylinders 15, without the need for complex parts, making it easy to achieve mass production.

[0035] A semi-cylinder 15 is inserted into a corresponding semi-circular groove 14, and a rotating hole is provided on the upper surface edge of the semi-cylinder 15, with a rotating shaft rotatably connected to the inner cavity of the rotating hole. The insertion connection between the semi-cylinder 15 and the semi-circular groove 14 enhances the connection stability between the L-shaped heat-conducting fin 10 and the outer shell 1, preventing the L-shaped heat-conducting fin 10 from shifting in the vertical direction. The rotatable connection between the rotating hole on the semi-cylinder 15 and the rotating shaft allows the L-shaped heat-conducting fin 10 to rotate around the shaft, adjusting the contact angle between the L-shaped heat-conducting fin 10 and the heat source according to the installation angle of the heat source inside the equipment or the inner cavity space of the outer shell 1, ensuring smooth heat conduction to the L-shaped heat-conducting fin 10. The insertion connection improves the connection reliability between the L-shaped heat-conducting fin 10 and the outer shell 1, preventing the fins from loosening during equipment operation. The rotating structure gives the L-shaped heat-conducting fin 10 adjustable angle, adapting to different heat source installation scenarios, improving the applicability and heat dissipation flexibility. The overall structure is simple, the assembly steps are convenient, and no complex processing technology is required.

[0036] A semi-circular locking block 16 is added to the upper surface of the semi-cylinder 15, and the top end of the rotating shaft is connected to the lower edge of the semi-circular locking block 16. The lower surface of the semi-circular locking block 16 is rotatably fitted with the upper surface of the short side of the L-shaped heat-conducting fin 10. The semi-circular locking block 16 is set on the upper surface of the semi-cylinder 15 to restrict the vertical movement of the L-shaped heat-conducting fin 10 and prevent the fin from detaching from the semi-cylinder 15 due to equipment vibration or other factors. The connection between the top end of the rotating shaft and the semi-circular locking block 16 does not affect the rotation function of the rotating shaft and the rotating hole, and the semi-circular locking block 16 can limit the rotation of the rotating shaft. The rotatable fit between the lower surface of the semi-circular locking block 16 and the upper surface of the short side of the L-shaped heat-conducting fin 10 ensures that the L-shaped heat-conducting fin 10 always remains in contact with the semi-circular locking block 16 when rotating around the rotating shaft. The contact of the locking block 16 does not compromise the overall structural stability, nor does it affect the heat conduction function of the L-shaped heat-conducting fin 10. The semi-circular locking block 16 effectively prevents the L-shaped heat-conducting fin 10 from vertically shifting, improving the stability of the fin installation. While ensuring the rotation function, the rotational contact between the semi-circular locking block 16 and the fin further ensures the stability of the heat conduction path. The structure is compact, and the newly added semi-circular locking block 16 does not change the core function of the original component, making it easy to integrate with the semi-cylinder 15 and the rotating shaft.

[0037] In this solution: when the drone driver is running, the motor 7 and the power battery 9 generate heat. The electronic speed controller 8 works in conjunction with the motor 7 and the power battery 9 through the circuit. The rotating shaft 5 is connected to the rotating end of the motor 7 through the transmission component to ensure the normal operation of the driver.

[0038] At this time, the short side of the L-shaped heat-conducting fin 10 is in close contact with the motor 7 and the power battery 9. An elastic heat-conducting pad 13 is provided on the front of the short side of the L-shaped heat-conducting fin 10. The elastic heat-conducting pad 13 will fill the tiny gap between the short side and the motor 7 and the power battery 9, and stably conduct heat to the L-shaped heat-conducting fin 10. The L-shaped heat-conducting fin 10 is positioned by the semi-circular groove 14 on the short side and the semi-circular cylinder 15 around the bottom of the inner cavity of the outer shell 1. The semi-circular cylinder 15 is inserted and connected to the semi-circular groove 14. The rotating shaft in the rotating hole on the upper surface of the semi-circular cylinder 15 is connected to the semi-circular locking block 16. The lower surface of the semi-circular locking block 16 rotates and fits against the upper surface of the short side of the L-shaped heat-conducting fin 10, which not only restricts the displacement of the L-shaped heat-conducting fin 10, but also allows it to adjust its angle to ensure contact with the heat source.

[0039] The long side of the L-shaped heat-conducting fin 10 extends towards the middle of the inner cavity of the outer shell 1. The perforated hole 11 on the front of the long side allows airflow to pass through. The serrated edges 12 on the upper surface of the long side and both sides of the short side increase the contact area with air, thereby raising the conducted heat from the bottom of the inner cavity of the outer shell 1 to the middle and upper part, and avoiding heat accumulation.

[0040] When the cooling fan 6 is turned on, the external cold air is filtered by the dust filter 18 at the air inlet end of the air guide groove 17 at the bottom of the inner cavity of the outer shell 1, and then flows along the air guide groove 17 to the motor 7 in the center of the inner cavity of the outer shell 1. The cold air is fully mixed with the hot air conducted to the upper middle part by the L-shaped heat conduction fins 10, and enters from the air inlet end of the heat dissipation hole 3 with heat, and then is discharged from the outer shell 1 through the dust filter plate 4 at the air outlet end of the heat dissipation hole 3 and the cooling fan 6, forming a convection channel with bottom inlet and top outlet, and continuously achieving the dual cooling effect.
