Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and more specifically to a UAV power amplifier load heat dissipation device based on heat dissipation pipes. Background Technology

[0002] With the continuous development of drone technology, small rotary-wing drones are widely used in aerial photography, logistics delivery, rescue monitoring, and agricultural plant protection due to their advantages such as flexible operation, convenient take-off and landing, and wide applicability. However, small rotary-wing drones face many heat dissipation problems during operation, which to some extent limits their performance improvement and application scope expansion.

[0003] The power system, electronic control system, and battery of a small rotary-wing drone generate a significant amount of heat during operation. For example, the motor generates heat due to electromagnetic and mechanical losses when driving the rotor, the electronic speed controller (ESC) generates heat when adjusting the motor speed and current, and the battery generates heat due to internal chemical reactions during charging and discharging. If this heat cannot be dissipated effectively and promptly, the temperature of the drone components will rise, leading to a series of problems. On the one hand, high temperatures will degrade the performance of the motor and battery, reducing flight efficiency and endurance, and shortening the lifespan of components. On the other hand, electronic components are prone to failure in high-temperature environments, affecting the stability and reliability of the drone, and may even lead to flight accidents.

[0004] Currently, common heat dissipation methods for small rotary-wing drones mainly include natural cooling and forced cooling. Natural cooling relies primarily on natural air convection and the thermal radiation of the components themselves to dissipate heat. This method is simple in structure and requires no additional energy, but its cooling effect is often limited for drones with high heat dissipation requirements. Forced cooling, on the other hand, uses miniature fans installed on the drone or the airflow from the rotor to force ventilation. Although the cooling effect is better, it increases the drone's energy consumption, weight, and structural complexity. Furthermore, the operation of components such as fans can generate noise and vibration, affecting the drone's flight performance and stealth capabilities.

[0005] Therefore, designing an efficient, reliable, and flight-performance-independent heat dissipation structure for small rotary-wing UAVs within the limited space and weight constraints has become a pressing issue in the field of UAV technology. Based on this, proposing an improved scheme that utilizes a pipe-based heat dissipation circuit structure to enhance the heat dissipation effect of UAVs has significant practical implications. Utility Model Content

[0006] In view of this, the present invention provides a heat dissipation device for the power amplifier load of a drone based on a heat dissipation pipeline, which aims to solve the above-mentioned technical problems.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A heat dissipation device for the power amplifier load of a drone based on a heat dissipation pipe includes:

[0009] The drone body has an inner cavity that serves as a battery and control element mounting cavity, with an opening at the bottom of the battery and control element mounting cavity;

[0010] A heat sink is provided at the bottom opening of the battery and control element mounting cavity, and the top surface of the heat sink is used to abut against and support the battery and control element inside the battery and control element mounting cavity; a heat dissipation duct is integrated on the bottom surface of the heat sink, and a miniature blower assembly is installed on the bottom surface of the heat sink, and the miniature blower assembly blows air to the end of the heat dissipation duct.

[0011] The lower support plate is connected to the bottom of the UAV body and is located below the heat sink. The lower support plate has a support member for pressing the heat sink upward.

[0012] Through the above technical solution, this utility model, by combining a heat sink, a heat dissipation duct, and a micro blower assembly, can effectively dissipate the heat generated by the drone's battery and control components, improve heat dissipation efficiency, and at the same time, does not significantly increase the drone's weight and energy consumption. The structure is simple and reliable, which is conducive to the stable flight and performance improvement of the drone.

[0013] Preferably, in the above-mentioned UAV power amplifier load heat dissipation device based on heat dissipation pipes, the edge of the heat dissipation plate has a side panel perpendicular to its surface, and the side panel is slidably connected to the bottom opening of the battery and control component mounting cavity. The slidable connection between the side panel of the heat dissipation plate and the bottom opening of the battery and control component mounting cavity facilitates the installation and removal of the heat dissipation plate and provides a certain degree of protection for the battery and control components.

[0014] Preferably, in the above-mentioned UAV power amplifier load heat dissipation device based on heat dissipation pipes, the heat dissipation duct includes a main pipe and branch pipes connected to both sides of the main pipe, and the ends of both the main pipe and the branch pipes are open structures. This design helps to form multiple heat dissipation channels, allowing airflow to flow more evenly across the heat dissipation plate and improving the overall heat dissipation effect.

[0015] Preferably, in the above-mentioned UAV power amplifier load heat dissipation device based on a heat dissipation pipe, the end of the branch pipe away from the main pipe is bent downwards, so that when the UAV body moves downwards, the reaction force can blow external airflow into the branch pipe. This can further enhance the airflow circulation within the heat dissipation duct, improve heat dissipation capacity, and requires no additional energy consumption.

[0016] Preferably, in the above-mentioned UAV power amplifier load heat dissipation device based on heat dissipation pipes, the micro blower assembly includes a micro motor and fan blades. The micro motor is fixed to the bottom surface of the heat sink, and the fan blades are fixed to the power output shaft of the micro motor, with the fan blades corresponding to one end of the main pipe. The structure is simple and compact, easy to install on the bottom surface of the heat sink, and can provide a stable airflow to the end of the main pipe, ensuring airflow within the heat dissipation duct and thus improving heat dissipation efficiency.

[0017] Preferably, in the above-mentioned UAV power amplifier load heat dissipation device based on heat dissipation pipes, the ends of the main pipe and the fan blades form a flared structure. This helps to increase the air intake volume, allowing the airflow to enter the main pipe more smoothly, further improving the blowing effect of the micro blower assembly and enhancing the heat dissipation performance.

[0018] Preferably, in the above-mentioned UAV power amplifier load heat dissipation device based on heat dissipation pipes, the bottom surface of the heat dissipation plate has fins, and the fins are in a bent arc shape, so that the main pipe and the branch pipe can be inserted into the fins. This increases the heat dissipation area, and the fact that the main pipe and the branch pipe can be inserted into the fins ensures that the heat dissipation ducts and the heat dissipation plate are tightly connected, improving the overall integrity and stability of the heat dissipation device.

[0019] Preferably, in the above-mentioned UAV power amplifier load heat dissipation device based on heat dissipation pipes, the heat dissipation plate is provided with weight-reducing heat dissipation holes. This reduces the weight of the heat dissipation plate itself while increasing the airflow path, which helps dissipate heat and further improves heat dissipation efficiency.

[0020] Preferably, in the above-mentioned UAV power amplifier load heat dissipation device based on heat dissipation pipes, the lower support plate is an annular plate, which is connected to the bottom of the UAV body by bolts. The annular through hole of the lower support plate avoids the heat dissipation pipe. Installation is convenient and secure; the annular through hole avoids the heat dissipation pipe, does not hinder its normal operation, and ensures the integrity of the heat dissipation device.

[0021] Preferably, in the above-mentioned UAV power amplifier load heat dissipation device based on heat dissipation pipes, the support member includes a push rod and a spring; the push rod passes through the lower support plate, and the top end of the push rod has a limiting head, the limiting head abutting against the bottom surface of the heat dissipation plate, and the bottom end of the push rod has a support foot; the spring is sleeved on the push rod and is pressed tightly between the limiting head and the lower support plate. This allows the heat dissipation plate to be in close contact with the battery and control components, ensuring effective heat transfer, while also providing good support and stability for the heat dissipation plate, thus improving the reliability of the heat dissipation device.

[0022] As can be seen from the above technical solution, compared with the prior art, this utility model discloses a heat dissipation device for UAV power amplifier load based on heat dissipation pipes, which has the following beneficial effects:

[0023] 1. Improved heat dissipation performance: Through the coordinated work of heat sink, heat dissipation duct and miniature blower assembly, the heat generated by the battery and control components during operation can be effectively dissipated, improving heat dissipation efficiency, preventing performance degradation and failure of components due to high temperature, and ensuring stable and reliable operation of the drone.

[0025] 3. Reduced energy consumption and weight: While achieving efficient heat dissipation, the weight and energy consumption of the drone are not significantly increased, which helps to improve the drone's flight performance and endurance.

[0026] 4.

[0051] The drone body 1 has an inner cavity that is a battery and control element mounting cavity 11, and the bottom of the battery and control element mounting cavity 11 is open.

[0052] Heat sink 2 is located at the bottom opening of the battery and control component mounting cavity 11, and the top surface of heat sink 2 is used to contact and support the battery and control component inside the battery and control component mounting cavity 11; the bottom surface of heat sink 2 is integrated with heat dissipation duct 4, and a miniature blower assembly 5 is installed on the bottom surface of heat sink 2, which blows air to the end of heat dissipation duct 4.

[0053] The lower support plate 3 is connected to the bottom of the drone body 1 and is located below the heat sink 2. The lower support plate 3 has a support member 6, which is used to push the heat sink 2 upward.

[0054] See appendix Figure 5 The heat sink 2 has a side panel 21 perpendicular to its surface along its edge, and the side panel 21 is slidably connected to the bottom opening of the battery and control element mounting cavity 11.

[0055] See appendix Figure 6 The heat dissipation duct 4 includes a main pipe 41 and branch pipes 42 connected to both sides of the main pipe 41. The ends of the main pipe 41 and the branch pipes 42 are both open structures.

[0056] To further optimize the above technical solution, the end of the branch pipe 42 away from the main pipe 41 is bent downwards, so that when the UAV body 1 moves downwards, it can blow external airflow into the branch pipe 42 through the reaction force.

[0057] See appendix Figure 7 The miniature blower assembly 5 includes a miniature motor 51 and a fan blade 52. The miniature motor 51 is fixed to the bottom surface of the heat sink 2, and the fan blade 52 is fixed to the power output shaft of the miniature motor 51. The fan blade 52 corresponds to one end of the main pipe 41.

[0058] To further optimize the above technical solution, the ends of the main pipe 41 and the fan blade 52 are formed into a flared structure 411.

[0059] To further optimize the above technical solution, the bottom surface of the heat sink 2 has fins 22, which are in a bent arc shape, so that the main pipe 41 and the branch pipe 42 can be inserted into the fins 22.

[0060] To further optimize the above technical solution, the heat sink 2 is provided with weight-reducing heat dissipation holes 23.

[0061] See appendix Figure 8 The lower support plate 3 is an annular plate. The lower support plate 3 is connected to the bottom of the UAV body 1 by bolts 31. The annular through hole of the lower support plate 3 avoids the heat dissipation duct 4.

[0062] To further optimize the above technical solution, the support member 6 includes a top rod 61 and a spring 62; the top rod 61 passes through the lower support plate 3, and the top end of the top rod 61 has a limiting head 611, which abuts against the bottom surface of the heat sink 2, and the bottom end of the top rod 61 has a support foot 612; the spring 62 is sleeved on the top rod 61 and is pressed between the limiting head 611 and the lower support plate 3.

[0063] The working principle of the UAV power amplifier load heat dissipation device based on heat dissipation pipes provided by this utility model is as follows:

[0064] During drone operation, the heat generated by the battery and control components is transferred to the heat sink 2. The micro motor 51 of the micro blower assembly 5 drives the fan blades 52 to rotate, blowing airflow into the main pipe 41 of the cooling duct 4. The airflow flows within the main pipe 41 and is accelerated out through the flared structure 411, forming a cooling duct. Simultaneously, when the drone body 1 moves downward, the external airflow is blown into the branch pipe 42 under the reaction force, further enhancing the cooling effect.

[0065] The bottom fins 22 of the heat sink 2 increase the heat dissipation area, while the weight-reducing heat dissipation holes 23 reduce the weight of the heat sink and assist in heat dissipation. The support member 6 on the lower support plate 3 includes a push rod 61 and a spring 62. The limiting head 611 of the push rod 61 presses against the bottom surface of the heat sink 2 to ensure that the heat sink is in close contact with the battery and control components. At the same time, the elastic force of the spring 62 keeps the heat sink and the lower support plate stably supported, improving the reliability of the heat dissipation device.
