[0038] Please refer to Figures 1 to 11. Another air-cooled laser provided by the embodiments of this application includes a main structure 1, an air supply assembly 2, and a heat-generating device 3 mounted on the main structure 1. The main structure 1 includes at least two substructures arranged along the axial direction of the main structure 1. Each substructure includes an inner heat dissipation part 14 and an outer heat dissipation part 15 disposed around the inner heat dissipation part 14.

[0039] Among them, at least two substructures are spliced together along the axial direction of the main structure 1.
[0040] In this embodiment, the air-cooled laser is divided into at least two axially arranged substructures, each substructure including an inner heat dissipation section 14, an outer heat dissipation section 15, and a heat dissipation channel 5 located between the inner heat dissipation section 14 and the outer heat dissipation section 15. Adjacent heat dissipation channels 5 are connected. A heat dissipation component 4 is provided in the heat dissipation channel 5 and connected to the inner heat dissipation section 14 and / or the outer heat dissipation section 15. The air supply component 2 causes airflow to form in the heat dissipation channel 5 and carries away the heat of the heat dissipation component 4, thereby improving the heat dissipation efficiency of the heat-generating device 3.
[0041] The technical solution of this application will now be described in conjunction with specific embodiments.
[0042] In one embodiment, please refer to Figures 1, 3, and 4. The air-cooled laser also includes a housing 6, in which a receiving cavity is formed, and the main structure 1 is housed within the receiving cavity.
[0043] In one embodiment, referring to Figures 2, 3, 5, and 6, the main structure 1 includes a first substructure 11 and a second substructure 12. The first substructure 11 includes a plurality of first mounting planes distributed sequentially along the circumference. The second substructure 12 is a cylindrical structure. The heating device 3 includes a pump source 31 and an optical fiber 32. The pump source 31 is disposed on the inner wall of the inner heat dissipation part 14 of the first substructure 11 and / or the first mounting plane of the outer heat dissipation part 15. The optical fiber 32 is wound around the outer wall of the outer heat dissipation part 15 of the second substructure 12.
[0044] The heating device 3 can also be at least one of the following: fiber optic coupler 32, main control board, and power supply board 33.
[0045] An adhesive layer is provided between the heating element 3 and the main structure 1, and the heating element 3 and the main structure 1 can be bonded together by the adhesive layer, which can be double-sided adhesive.
[0046] The heating element 3 can also be fixed to the main structure 1 by snapping it into the main structure 1, or by connecting the heating element 3 to the main structure 1 with bolts and screw holes.
[0047] The main structure 1 includes multiple first mounting planes and cylindrical structures as substructures to facilitate assembly with different heating devices 3.
[0048] It is understood that the first substructure 11 includes multiple first mounting planes distributed sequentially along the circumference. The first mounting planes are relatively flat and facilitate the installation of any one of the fiber optic coupler 32, main control board, power supply board 33, and pump source 31. The second substructure 12 is a cylindrical structure with an arc surface on the outer wall. The arc surface is conducive to the winding and setting of the fiber optic 32. The fiber optic 32 is wound on the arc surface to reduce the overall volume of the air-cooled laser.
[0049] It should be noted that the inner heat dissipation part 14 and the outer heat dissipation part 15 of the first substructure 11 are both multi-faceted prism structures, the inner heat dissipation part 14 of the second substructure 12 is a multi-faceted prism structure, and the outer heat dissipation part 15 of the second substructure 12 is a cylindrical structure. The multi-faceted prism structure can be used to set up the fiber optic coupler 32, the main control board, the power board 33, and the pump source 31, while the cylindrical structure can be used to set up the fiber optic 32.
[0050] It is worth noting that the outer wall of the outer heat dissipation part 15 of the second substructure 12 may be provided with a fiber routing groove surrounding the outer heat dissipation part 15. The fiber routing groove surrounds the second substructure 12, and the optical fiber 32 is located in the fiber routing groove. By placing the optical fiber 32 in the fiber routing groove, on the one hand, the bonding strength between the optical fiber 32 and the outer heat dissipation part 15 of the second substructure 12 can be enhanced. On the other hand, since only a part of the optical fiber 32 is located in the fiber routing groove, by hiding the optical fiber 32 in the fiber routing groove, the overall volume of the air-cooled laser is further reduced.
[0051] In this embodiment, the main structure 1 includes at least a multi-faceted prism structure and a cylindrical structure arranged along the axial direction. The multi-faceted prism structure and the cylindrical structure provide different surfaces for setting the heating device 3, so as to facilitate the assembly with different heating devices 3 and reduce the overall volume of the air-cooled laser.
[0052] In one embodiment, referring to Figures 9 and 10, the heat sink 4 is a fin. The fins in the first substructure 11 are connected between the outer heat sink 15 and / or the inner heat sink 14. The fins in the second substructure 12 are connected to the inner wall of the outer heat sink 15. The fin density in the first substructure 11 is greater than the fin density in the second substructure 12.
[0053] The first substructure 11 may have a heating device 3 provided only on the first mounting plane of the outer heat dissipation part 15, and the fins in the first substructure 11 may be connected only to the inner wall of the outer heat dissipation part 15.
[0054] The first substructure 11 may have a heating device 3 provided only on the inner wall of the inner heat dissipation part 14, and the fins in the first substructure 11 may be connected only to the outer wall of the inner heat dissipation part 14.
[0055] In this substructure, the first mounting plane of the outer heat dissipation part 15 and the inner wall of the inner heat dissipation part 14 can both be provided with heat-generating devices 3, and the fins in the first substructure 11 are connected between the inner wall of the outer heat dissipation part 15 and the outer wall of the inner heat dissipation part 14.
[0056] The main structure 1 includes two opposite ports, which are connected to the heat dissipation channel 5.
[0057] It is understandable that since the heat-generating device 3 set in the first substructure 11 is a pump source 31, its heat generation is greater than that of the optical fiber 32 set on the outer wall of the outer heat dissipation part 15 of the second substructure 12. This results in the fin density corresponding to the pump source 31 being greater than the fin density corresponding to the optical fiber 32. By increasing the fin density corresponding to the pump source 31, the heat dissipation efficiency of the pump source 31 is improved, so that the pump source 31, which generates more heat, can be better dissipated compared to the optical fiber 32, which generates less heat.
[0058] Understandably, the heat dissipation principle of the fins is as follows: the fins are arranged opposite to the heating device 3, and the fins are located on the back side of the surface on which the heating device 3 is located. The heat from the heating device 3 is conducted to the fins through the outer heat dissipation part 15 and / or the inner heat dissipation part 14. The air supply component 2 forms an airflow in the heat dissipation channel 5. The airflow enters the heat dissipation channel 5 from the port on the side where the air supply component 2 is located, and is transmitted along the heat dissipation channel 5 to the port on the other side and discharged to the outside. The airflow carries away the heat from the fins to achieve heat dissipation of the heating device 3.
[0059] It should be noted that since the main structure 1 includes an inner heat dissipation part 14 and an outer heat dissipation part 15, both the inner heat dissipation part 14 and the outer heat dissipation part 15 can be equipped with heat-generating devices 3. On the one hand, the heat-generating devices 3 can be hidden inside the inner heat dissipation part 14, which can reduce the overall volume of the air-cooled laser. On the other hand, the light-emitting device can be thermally connected to the fins through both the inner heat dissipation part 14 and the outer heat dissipation part 15, thereby improving the heat dissipation efficiency of the heat-generating devices 3.
[0060] In this embodiment, the heat dissipation efficiency of the pump source 31 inside the first substructure 11 is enhanced by making the fin density inside the first substructure 11 greater than that inside the second substructure 12.
[0061] In one embodiment, the air supply assembly 2 may also be disposed between adjacent substructures.
[0062] In one embodiment, referring to Figures 3 and 11, the substructure further includes a third substructure 13. The third substructure 13 is disposed on the side of the second substructure 12 away from the first substructure 11 along the axial direction. The third substructure 13 includes a plurality of second mounting planes distributed sequentially along the circumference. The third substructure 13 includes a first region and a second region. The heat generation of the heating device 3 in the first region is greater than the heat generation of the heating device 3 in the second region. The fins in the third substructure 13 include a first fin 41 and a second fin 42. The length of the first fin 41 is greater than the length of the second fin 42. The first fin 41 is disposed in the first region, and the second fin 42 is disposed in the second region.
[0063] The heat dissipation area of the first fin 41 is larger than that of the second fin 42, which makes the heat dissipation efficiency of the first fin 41 greater than that of the second fin 42.
[0064] It is understandable that a first fin 41 can be provided in a first region that generates more heat than the second region. The first fin 41 is longer than the second fin 42 and has a larger heat dissipation area, thereby improving the heat dissipation efficiency of the corresponding position of the chip.
[0065] In one embodiment, referring to Figures 3, 6, and 7, the substructure further includes a third substructure 13. The third substructure 13 is disposed on the side of the second substructure 12 away from the first substructure 11 along the axial direction. The third substructure 13 includes a plurality of second mounting planes distributed sequentially along the circumference. The heat-generating device 3 also includes a power board 33. The power board 33 includes a chip and other components. The power board 33 is disposed on the inner wall of the inner heat dissipation part 14 of the third substructure 13, and the fins are disposed on the outer wall of the inner heat dissipation part 14 and are disposed opposite to the chip; and / or; the power board 33 is disposed on the second mounting plane of the outer heat dissipation part 15 of the third substructure 13, and the fins are disposed on the inner wall of the outer heat dissipation part 15 and are disposed opposite to the chip.
[0066] The fins can be offset from other components.
[0067] It is understandable that since the heat generated by the power board 33 mainly comes from the chip, while the heat generated by other components is low or non-existent, by not setting fins in the relative positions of other parts, the number of fins can be reduced, leaving more space in the heat dissipation channel 5. In some embodiments, some heat-generating devices 3 can also be set in the side wall of the heat dissipation channel 5. Since some heat-generating devices 3 are hidden in the heat dissipation channel 5, they do not occupy the overall volume of the air-cooled laser, thus reducing the overall volume of the air-cooled laser.
[0068] In one embodiment, referring to FIG6, the inner heat dissipation part 14 and the outer heat dissipation part 15 of the first substructure 11 and the third substructure 13 are both multi-faceted prism structures, the inner heat dissipation part 14 of the second substructure 12 is a multi-faceted prism structure, and the outer heat dissipation part 15 of the second substructure 12 is a cylindrical structure.
[0069] The top surface of the aforementioned polyhedral prism structure can be any one of a regular hexagon, a regular octagon, or a regular dodecagon.
[0070] In one embodiment, referring to FIG5, the first mounting plane includes a first sub-surface and a second sub-surface arranged at intervals. The first sub-surface is provided with a heating device 3, and the second sub-surface is staggered from the heating device 3. The surface area of the first sub-surface is greater than or equal to the surface area of the second sub-surface, and the heat sink 4 is provided on the back side of the first sub-surface.
[0071] The second sub-surface may not have a heating element 3. The second sub-surface serves as a transition between adjacent first sub-surfaces and also helps to prevent the heating elements 3 on adjacent first sub-surfaces from interfering with or short-circuiting each other.
[0072] Both the first and second sub-faces can be rectangles.
[0073] It is understandable that, compared with air-cooled lasers in related technologies, this embodiment can effectively reduce the overall size of the laser by mounting the heating device close to the first sub-surface in the first mounting plane, making it easier to carry and thus improving the portability of the laser.
[0074] In one embodiment, referring to Figures 3 and 6, the heat-generating device 3 further includes an optical cable head 9, which is disposed on the first mounting plane of the outer heat dissipation portion 15 of the first substructure 11.
[0075] In one embodiment, please refer to Figures 3, 6, 7 and 8. One end of the third substructure 13 is provided with an air supply component 2. The air supply component 2 includes blades 21 and a motor 22. The motor 22 is located inside the inner heat dissipation part 14 of the third substructure 13. The motor 22 is used to drive the blades 21 to rotate. A steering mechanism 10 is also connected between the motor 22 and the blades 21. The steering mechanism 10 is used to adjust the rotation direction of the blades 21.
[0076] The motor 22 is connected to the blade 21 via a rotating shaft. The motor 22 drives the rotating shaft to rotate, thereby realizing the rotation of the blade 21.
[0077] Among them, blade 21 is located at the end of the third substructure 13 that is far away from the first substructure 11.
[0078] Multiple blades 21 rotate around the same center to form a fan, and the number of blades 21 can be any of 4, 6, 8, 10 or 12.
[0079] Among them, adjacent blades 21 are arranged at equal intervals.
[0080] Among them, multiple blades 21 can be arranged in a centrally symmetrical manner about the same center.
[0081] It is understandable that the steering mechanism 10 is connected between the electrode and the blade 21. The steering mechanism 10 can be used to adjust the offset direction of the rotating shaft, so that the rotation direction of the blade 21 connected to the rotating shaft is improved. When the wind-cooled laser is applied to the drone, the rotation of the blade 21 can also play the role of the drone's take-off, landing and steering.
[0082] It should be noted that the steering mechanism 10 may also include multiple sub-steering units, each of which can be individually connected to a blade 21. The multiple blades 21 are set independently of each other, so that the rotation direction of each blade 21 can be individually controlled through the sub-steering units, thereby better adjusting the movement of the UAV in different directions.
[0083] In this embodiment, the air supply assembly 2 also includes blades 21, a motor 22, and a steering mechanism 10. The steering mechanism 10 is used to adjust the rotation direction of the blades 21, so that the air-cooled laser can be applied to drones. The air supply assembly 2 of the air-cooled laser can realize the functions of drone lifting, turning and steering.
[0084] In one embodiment, referring to Figures 2, 5, and 6, the blade 21 includes a first part 201 and a second part 202 connected to each other. The first part 201 is aligned with the heat dissipation channel 5, and the second part 202 is located outside the first part 201. The angle between the second part 202 and the plane perpendicular to the axial direction is less than or equal to the angle between the first part 201 and the plane perpendicular to the axial direction.
[0085] The fan also includes an annular portion, with a first portion 201 connected to the inner wall of the annular portion and a second portion 202 connected to the outer wall of the annular portion. The first portion 201 and the second portion 202 rotate around the same center.
[0086] Understandably, the blade 21 can be fixed to the annular part. The first part 201 located inside the annular part is used to drive the gas to form an airflow in the heat dissipation channel 5. The second part 202 located outside the annular part is used to provide traction for the air-cooled laser or the drone containing the air-cooled laser, so that the air-cooled laser or the drone containing the air-cooled laser can rise, fall and turn under the drive of the air supply assembly 2.
[0087] It should be noted that since the second part 202 is fixed to the outer wall of the same annular part, when the drone containing the air-cooled laser needs to turn, the annular part is deflected relative to the plane perpendicular to the axis under the drive of the turning mechanism 10, so that the drone moves in the direction of the deflection and realizes the turning of the drone.
[0088] In this embodiment, the air-cooled component includes a first part 201 connected to the inner wall of the annular portion and a second part 202 connected to the outer wall of the annular portion. The second part 202 is used to drive the drone to rise, fall, and turn, thereby integrating the air-cooled laser into the drone. The drone does not need to be equipped with additional blades 21 for rising, falling, and turning.
