[0002] Extended-range drones have longer endurance than traditional drones. Usually, extended-range drones are equipped with other power systems, such as larger batteries or generators for endurance. Generators require heat sinks to dissipate heat during operation. The heat sinks are mainly composed of water-cooled plates to dissipate the coolant carrying heat inside the generator.

[0003] In the prior art, for example, patent publication number CN221547090U discloses a heat dissipation water cooling plate for a diesel generator, comprising a water inlet pipe, a water outlet pipe provided at the lower portion of the water inlet pipe, the water inlet pipe and the water outlet pipe being arranged transversely, one side of the water inlet pipe and the water outlet pipe being connected by a connecting plate, a plurality of evenly distributed cooling rollers being provided between the water inlet pipe and the water outlet pipe, connecting pipes being provided at both ends of the cooling roller, the water inlet pipe and the water outlet pipe being connected and fixed to the side wall with the connecting pipes, and the outer wall of the cooling roller being evenly distributed with heat sinks along the axis of the cooling roller.

[0004] The above structure uses a cooling drum to enhance the heat dissipation effect of the coolant. However, when the generator on the drone is running, it is unable to dissipate heat for the generator on the drone. The commonly used heat dissipation rack cannot be assembled with the drone and occupies a large area. Utility Model Content

[0005] In view of this, the purpose of the present invention is to propose a heat sink for the generator of an extended-range UAV to solve the problem that the generator on the UAV cannot be cooled, the commonly used heat sink cannot be assembled with the UAV, and occupies a large area.

[0006] Based on the above purpose, the utility model provides a heat sink for a generator of an extended-range drone, including a water-cooling plate group, wherein the water-cooling plate group includes a first water-cooling plate and a second water-cooling plate, wherein a gap is left between the first water-cooling plate and the second water-cooling plate after being assembled, and corresponding semicircular grooves are opened on one side of the first water-cooling plate and the second water-cooling plate, and the semicircular grooves are used for clamping the drone frame;

[0008] A slot is provided on one side of the first water cooling plate, a clamping block is slidably installed inside the slot, a spring is connected between the clamping block and the slot, and a clamping hole corresponding to the slot is provided on one side of the second water cooling plate.

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0024] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, a heat sink for a generator of an extended-range drone includes a water-cooling plate assembly 1, which includes a water-cooling plate 1 2 and a water-cooling plate 2 3. A gap is left between the water-cooling plate 1 2 and the water-cooling plate 2 3 after they are assembled, and corresponding semicircular grooves 17 are opened on one side of the water-cooling plate 1 2 and the water-cooling plate 2 3. The semicircular grooves 17 are used to clamp the drone frame;

[0025] Water-cooled plates 1 2 and 2 3 are further provided with a water cavity 4 inside, and heat dissipation racks 6 are fixedly mounted on the outside of water-cooled plates 1 2 and 2 3. Baffles 5 are arranged in a rectangular array inside the water cavity 4, with intervals between adjacent groups of baffles 5 to form a flow channel 16 inside the water cavity 4. A water inlet pipe 7 and a water outlet pipe 8, both of which are connected to the flow channel 16, are fixedly connected at both ends of the water cavity 4. Both the water inlet pipe 7 and the water outlet pipe 8 are connected to the generator cooling pipe.

[0026] A slot hole 12 is provided on one side of the water-cooling plate 1, a clamping block 14 is slidably installed inside the slot hole 12, a spring 13 is connected between the clamping block 14 and the slot hole 12, and a clamping hole 15 corresponding to the slot hole 12 is provided on one side of the water-cooling plate 2 3.

[0027] In this embodiment, the water-cooling plate 1 2 and the water-cooling plate 2 3 are first closed, so that the semicircular grooves 17 of the water-cooling plate 1 2 and the water-cooling plate 2 3 wrap around the UAV frame. The clamping block 14 in the slot 12 in the water-cooling plate 1 2 is compressed by the spring 13, so that the clamping block 14 on one side of the water-cooling plate 1 2 is inserted into the clamping hole 15 of the water-cooling plate 2 3, completing the preliminary installation of the water-cooling plate assembly 1.

[0028] When the temperature of the generator on the UAV is high, the coolant enters the interior of the water-cooling plate group 1 through the water inlet pipe 7 and enters the water cavity 4. The baffles 5 distributed in the internal rectangular array and the flow channels 16 formed by the interval arrangement are used to change the flow path of the water. The coolant flows in the flow channel 16, increasing the flow time of the water cooling in the water cavity 4. At the same time, during the flight, due to the gap between the closed water-cooling plate 1 2 and the water-cooling plate 2 3, the air flow flows between the water-cooling plate 1 2 and the water-cooling plate 2 3 to reduce the temperature. The coolant that loses heat is discharged through the water outlet pipe 8 to increase the heat dissipation effect. It can dissipate heat for the generator on the UAV and facilitate assembly with the UAV.

[0029] As an implementation method, Figure 4 As shown, the water cooling plate 1 2 and the water cooling plate 2 3 are arranged in a mirror-symmetrical manner, and the water cooling plate 1 2 and the water cooling plate 2 3 are made of the same material structure.

[0030] In this embodiment, the UAV frame is wrapped with the mirror-symmetrically arranged water-cooling plate 1 2 and water-cooling plate 2 3 to facilitate contact with the air and reduce the occupied area.

[0031] As an implementation method, Figure 1 、 Figure 2 and Figure 3 As shown, the inner annular array of the semicircular groove 17 is provided with elastic rubber blocks 9, which are rubber components.

[0032] In this embodiment, since there is a gap between the water-cooling plate 1 2 and the water-cooling plate 2 3 after they are closed, the airflow enters the semicircular groove 17 through the gap. Under the resistance of the elastic rubber block 9 in the semicircular groove 17 against the frame, a gap is generated between the frame and the semicircular groove 17 for the airflow to be discharged, so that the airflow flows between the water-cooling plate 1 2 and the water-cooling plate 2 3 to reduce the temperature.

[0033] As an implementation method, Figure 1 and Figure 4 As shown, the heat dissipation frame 6 is configured as a grid shape, the exterior of the heat dissipation frame 6 and the exteriors of the water cooling plate 1 2 and the water cooling plate 2 3 are configured as matching arc surfaces, and the interior of the heat dissipation frame 6 is provided with coolant.

[0034] In this embodiment, since the curved grid-shaped heat dissipation frame 6 is wrapped around the outside of the water-cooling plate 1 2 and the water-cooling plate 2 3, when the coolant is passed into the water cavity 4, the coolant disposed inside the heat dissipation frame 6 further reduces the temperature inside the water cavity 4;

[0035] At the same time, during the flight of the UAV, the airflow generated by the flight acts on the grid-shaped heat sink 6 outside the water-cooling plate group 1. By utilizing the grid-shaped arrangement, the airflow cools the heat sink 6 and the outside of the water cavity 4.

[0036] As an implementation method, Figure 3 and Figure 4 As shown, one side of the clamping block 14 is set as an inclined surface, and the clamping block 14 is set at the center of one side of the water-cooling plate 2.

[0037] In this embodiment, after the water-cooling plate 1 2 and the water-cooling plate 2 3 are aligned, the water-cooling plate 1 2 and the water-cooling plate 2 3 are closed, and the clamping block 14 in the slot 12 in the water-cooling plate 1 2 is compressed by the spring 13, and the inclined surface of one side of the clamping block 14 is clamped into the inside of the clamping hole 15, so that the water-cooling plate 1 2 and the water-cooling plate 2 3 are clamped together, which is convenient for assembly and preliminary positioning.

[0038] As an implementation method, Figure 1 As shown, the water-cooling plate 1 2 and the water-cooling plate 2 3 are provided with mounting holes 10 around them, and fastening bolts 11 are passed through and connected between two adjacent groups of mounting holes 10 .

[0039] In this embodiment, when the water-cooling plate 1 2 corresponds to the water-cooling plate 2 3, the water-cooling plate 1 2 and the water-cooling plate 2 3 are closed, and then the fastening bolts 11 are combined with the mounting holes 10 to complete the preliminary installation of the water-cooling plate group 1, thereby improving the connection strength of the entire water-cooling plate group 1 and preventing shaking when connected to the UAV frame.

[0040] Working principle: When in use, the water-cooling plate 1 2 and the water-cooling plate 2 3 are respectively sleeved on the outside of the extended-range UAV frame. During the installation process, the frame is located in the semicircular grooves 17 of the water-cooling plate 1 2 and the water-cooling plate 2 3. The elastic rubber blocks 9 in the water-cooling plate 1 2 and the water-cooling plate 2 3 are in contact with the frame. The water-cooling plate 1 2 is aligned with the water-cooling plate 2 3, and then the water-cooling plate 1 2 and the water-cooling plate 2 3 are closed. The clamping block 14 in the slot 12 in the water-cooling plate 1 2 is compressed by the spring 13, so that the clamping block 14 on one side of the water-cooling plate 1 2 is inserted into the clamping hole 15 of the water-cooling plate 2 3. Then, the fastening bolts 11 are combined with the mounting holes 10 to complete the preliminary installation of the water-cooling plate group 1.

[0041] After the water-cooling plate group 1 is installed on the UAV frame, the water inlet pipe 7 and the water outlet pipe 8 are connected to the generator coolant pipe. When the temperature of the generator is high, the coolant enters the water-cooling plate group 1 through the water inlet pipe 7. After entering the water cavity 4, the baffles 5 distributed in the internal rectangular array and the flow channels 16 formed by the interval arrangement are used to change the flow path of the water. The coolant flows in the flow channels 16, increasing the flow time of the water in the water cavity 4 to enhance the heat dissipation effect. At the same time, the coolant arranged inside the heat dissipation frame 6 further reduces the temperature in the water cavity 4.

[0042] At the same time, during the flight of the UAV, due to the gap between the water-cooling plate 1 2 and the water-cooling plate 2 3 after they are closed, the airflow enters the semicircular groove 17 through the gap, and the elastic rubber block 9 in the semicircular groove 17 resists the frame, and the airflow is discharged through the other side. The airflow also acts on the grid-shaped heat dissipation frame 6 outside the water-cooling plate group 1. The grid-shaped setting is used to cool the heat dissipation frame 6 and the outside of the water cavity 4. Under the dual action, the coolant that has lost heat is discharged through the water outlet pipe 8.
