[0038] See also Figures 1 to 11 Another air-cooled laser provided in an embodiment of the present application includes a main structure 1, an air supply assembly 2 and a heating device 3 installed 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 portion 14 and an outer heat dissipation portion 15 arranged around the inner heat dissipation portion 14, and a heat dissipation channel 5 is formed between the inner heat dissipation portion 14 and the outer heat dissipation portion 15: the air supply assembly 2 is connected to the main structure 1, and the air supply assembly 2 is used to drive the gas to form an airflow in the heat dissipation channel 5, and two adjacent substructures are detachably connected, and the heat dissipation channels 5 of adjacent substructures are connected to each other, and a heat dissipation member 4 connected to the inner heat dissipation portion 14 and / or the outer heat dissipation portion 15 is provided in the heat dissipation channel 5.

[0039] Among them, at least two substructures are spliced ​​with each other along the axial direction of the main structure 1.

[0040] In this embodiment, the air-cooled laser is divided into at least two substructures arranged along the axial direction, and each substructure includes an inner heat dissipation portion 14, an outer heat dissipation portion 15, and a heat dissipation channel 5 located between the inner heat dissipation portion 14 and the outer heat dissipation portion 15, adjacent heat dissipation channels 5 are connected, a heat sink 4 is arranged in the heat dissipation channel 5 and connected to the inner heat dissipation portion 14 and / or the outer heat dissipation portion 15, and the air supply component 2 forms an airflow in the heat dissipation channel 5 and takes away the heat of the heat sink 4, so as to improve the heat dissipation efficiency of the heating device 3.

[0041] The technical solution of the present application is now described in conjunction with specific embodiments.

[0042] In one embodiment, see Figure 1 , Figure 3 , Figure 4 The air-cooled laser further comprises a housing 6, a housing cavity is formed in the housing 6, and the main structure 1 is accommodated in the housing cavity.

[0043] In one embodiment, see Figure 2 , Figure 3 , Figure 5 , Figure 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 in sequence along the circumferential direction. 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 arranged 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 may also be at least one of an optical fiber 32 coupler, a main control board, and a power board 33 .

[0045] Among them, an adhesive layer is provided between the heating device 3 and the main structure 1 , and the heating device 3 and the main structure 1 can be bonded together through the adhesive layer, and the adhesive layer can be a double-sided adhesive.

[0046] The heating device 3 may also be engaged with the main structure 1, or the heating device 3 may also be fixed to the main structure 1 by connecting bolts with screw holes.

[0047] The substructure of the main structure 1 includes a plurality of first mounting planes and cylindrical structures, so as to facilitate assembly with different heating devices 3 .

[0048] It can be understood that the first substructure 11 includes a plurality of first mounting planes distributed in sequence along the circumferential direction. The first mounting plane is relatively flat and convenient for setting any one of the optical fiber 32 coupler, the main control board, the power board 33, and the pump source 31. The second substructure 12 is a cylindrical structure, and the outer wall of the cylindrical structure is an arc surface. The arc surface is conducive to the winding setting of the optical fiber 32. The optical fiber 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 portion 14 and the outer heat dissipation portion 15 of the first substructure 11 are both multi-faceted prism structures, the inner heat dissipation portion 14 of the second substructure 12 is a multi-faceted prism structure, and the outer heat dissipation portion 15 of the second substructure 12 is a cylindrical structure. The multi-faceted prism structure can be used to set the optical fiber 32 coupler, the main control board, the power board 33, and the pump source 31, and the cylindrical structure can be used to set the optical fiber 32.

[0050] It is worth noting that a fiber running groove surrounding the outer heat dissipation portion 15 may be provided on the outer wall of the outer heat dissipation portion 15 of the second substructure 12, the fiber running groove surrounds the second substructure 12, and the optical fiber 32 is located in the fiber running groove. By arranging the optical fiber 32 in the fiber running groove, on the one hand, the bonding strength between the optical fiber 32 and the outer heat dissipation portion 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 running groove, by hiding the optical fiber 32 in the fiber running groove, the overall volume of the air-cooled laser is further reduced.

[0051] In this embodiment, the main structure 1 at least includes 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, thereby reducing the overall volume of the air-cooled laser.

[0052] In one embodiment, see Fig. 9 , Fig.10The 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 setting density of the fins in the first substructure 11 is greater than the setting density of the fins in the second substructure 12.

[0053] The first substructure 11 may be provided with the heating device 3 only on the first mounting plane of the outer heat dissipation portion 15 , and the fins in the first substructure 11 may be connected only to the inner wall of the outer heat dissipation portion 15 .

[0054] The first substructure 11 may be provided with the heating device 3 only on the inner wall of the inner heat dissipation portion 14 , and the fins in the first substructure 11 may be connected only to the outer wall of the inner heat dissipation portion 14 .

[0055] The first mounting plane of the outer heat dissipation part 15 of the first substructure 11 and the inner wall of the inner heat dissipation part 14 can be provided with heating 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 can be understood that since the heating device 3 provided in the first substructure 11 is a pump source 31, the heat generated by the pump source 31 is greater than the optical fiber 32 provided on the outer wall of the outer heat dissipation portion 15 of the second substructure 12, the setting density of the fins corresponding to the pump source 31 is greater than the setting density of the fins corresponding to the optical fiber 32. By increasing the setting density of the fins corresponding to the pump source 31, the heat dissipation efficiency of the pump source 31 is improved, so that the pump source 31 with a larger heat generation can be better cooled than the optical fiber 32 with a smaller heat generation.

[0058] It can be understood that 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 of the surface on which the heating device 3 is arranged. The heat of 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 one side of the air supply component 2, and is transmitted along the heat dissipation channel 5 to the port on the other side and side by side to the outside. The airflow takes away the heat of 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 portion 14 and an outer heat dissipation portion 15, both the inner heat dissipation portion 14 and the outer heat dissipation portion 15 can be provided with a heating device 3. On the one hand, the heating device 3 can be hidden inside the inner heat dissipation portion 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 the inner heat dissipation portion 14 and the outer heat dissipation portion 15, thereby improving the heat dissipation efficiency of the heating device 3.

[0060] In this embodiment, the heat dissipation efficiency of the pump source 31 in the first substructure 11 is enhanced by making the arrangement density of the fins in the first substructure 11 greater than the arrangement density of the fins in the second substructure 12 .

[0061] In one embodiment, the air supply assembly 2 may also be disposed between adjacent substructures.

[0062] In one embodiment, see Figure 3 , Fig.11 The substructure also includes a third substructure 13, which is arranged on a side of the second substructure 12 axially away from the first substructure 11, and the third substructure 13 includes a plurality of second mounting planes distributed in sequence along the circumferential direction, and the third substructure 13 includes a first area and a second area, and the heat generated by the heating device 3 in the first area is greater than the heat generated by the heating device 3 in the second area, wherein 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 arranged in the first area, and the second fin 42 is arranged in the second area.

[0063] The heat dissipation area of ​​the first fin 41 is greater than the heat dissipation area of ​​the second fin 42 , so that the heat dissipation efficiency of the first fin 41 is greater than the heat dissipation efficiency of the second fin 42 .

[0064] It is understandable that the first fin 41 can be set in the first area which generates more heat than the second area. The first fin 41 is longer than the second fin 42 and has a larger heat dissipation area to improve the heat dissipation efficiency of the corresponding position of the chip.

[0065] In one embodiment, see Figure 3 , Figure 6 , Figure 7The substructure also includes a third substructure 13, which is arranged on a side of the second substructure 12 axially away from the first substructure 11, and the third substructure 13 includes a plurality of second mounting planes distributed in sequence along the circumferential direction. The heating device 3 also includes a power board 33, and the power board 33 includes a chip and other components. The power board 33 is arranged on the inner wall of the inner heat dissipation part 14 of the third substructure 13, and the fins are arranged on the outer wall of the inner heat dissipation part 14 and are arranged opposite to the chip; and / or; the power board 33 is arranged on the second mounting plane of the outer heat dissipation part 15 of the third substructure 13, and the fins are arranged on the inner wall of the outer heat dissipation part 15 and are arranged opposite to the chip.

[0066] The fins may be arranged in a staggered manner with respect to other components.

[0067] It can be understood that since the heat generated by the power board 33 mainly comes from the chip, and the heat generated by other components is low or no heat, by not setting fins at the relative positions of other parts, the number of fins can be reduced, and more space can be reserved in the heat dissipation channel 5. In some embodiments, some heating devices 3 can also be set on the side walls of the heat dissipation channel 5. Since some heating devices 3 are hidden in the heat dissipation channel 5, they do not occupy the overall volume of the air-cooled laser, and the overall volume of the air-cooled laser can be reduced.

[0068] In one embodiment, see Figure 6 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 multifaceted prism structure may be any one of a regular hexagon, a regular octagon, and a regular dodecagon.

[0070] In one embodiment, see Figure 5 The first mounting plane includes a first sub-surface and a second sub-surface arranged at an interval, the first sub-surface is provided with a heating device 3, and the second sub-surface is staggered with the heating device 3, wherein 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 arranged on the back side of the first sub-surface.

[0071] The second sub-surface may not be provided with a heating device 3. The second sub-surface serves as a transition between adjacent first sub-surfaces and also prevents the heating devices 3 on adjacent first sub-surfaces from interfering with or short-circuiting each other.

[0072] The first sub-surface and the second sub-surface may both be rectangular.

[0073] It can be understood that, compared with the air-cooled laser in the related art, this embodiment can effectively reduce the overall volume of the laser by closely mounting the heating device on 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, see Figure 3 , Figure 6 The heating device 3 further includes an optical cable head 9 , which is arranged on a first mounting plane of the outer heat dissipation portion 15 of the first substructure 11 .

[0075] In one embodiment, see Figure 3 , Figure 6 , Figure 7 , Figure 8 An air supply assembly 2 is provided at one end of the third substructure 13. The air supply assembly 2 includes blades 21 and a motor 22. The motor 22 is arranged on the inner side of the inner heat dissipation portion 14 of the third substructure 13, wherein 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, and 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, and the motor 22 drives the rotating shaft to rotate, thereby realizing the rotation of the blade 21.

[0077] The blade 21 is located at an end of the third substructure 13 away from the first substructure 11 .

[0078] Wherein, a plurality of blades 21 rotate around the same center of a circle to form a fan, and the number of the blades 21 may be any one of 4, 6, 8, 10, and 12.

[0079] Wherein, adjacent blades 21 are arranged at equal intervals.

[0080] The plurality of blades 21 may be centrally symmetrically arranged about the same center of a circle.

[0081] It can be understood 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 air-cooled laser is applied to a drone, the rotation of the blade 21 can also play the role of lifting and steering the drone.

[0082] It should be noted that the steering mechanism 10 can also include multiple sub-steering parts, each of which can be connected to a blade 21 individually, and the multiple blades 21 are independently arranged, so that the rotation direction of each blade 21 can be individually controlled by the sub-steering part, so as to better adjust the movement of the drone in different directions.

[0083] In this embodiment, the air supply component 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 component 2 of the air-cooled laser can realize the functions of lifting and steering the drone.

[0084] In one embodiment, see Figure 2 , Figure 5 , Figure 6 The blade 21 includes a first part 201 and a second part 202 which are connected to each other. The first part 201 is arranged in alignment with the heat dissipation channel 5, and the second part 202 is located on the outside of the first part 201, wherein 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 further comprises an annular portion, the first portion 201 is connected to the inner wall of the annular portion, the second portion 202 is connected to the outer wall of the annular portion, and the first portion 201 and the second portion 202 rotate around the same center of a circle.

[0086] It can be understood that the blades 21 can be fixed on the annular portion, and the first part 201 located on the inner side of the annular portion is used to drive the gas to form an airflow in the heat dissipation channel 5, and the second part 202 located on the outer side of the annular portion 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 be lifted, lowered and turned under the drive of the air supply component 2.

[0087] It should be noted that since the second parts 202 are all fixed to the outer wall of the same annular portion, when the drone containing the air-cooled laser needs to turn, the annular portion is deflected relative to the plane perpendicular to the axial direction under the drive of the steering mechanism 10, thereby causing the drone to move in the direction of the deflected side, thereby achieving 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 connected to the inner 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, and the drone does not need to be additionally provided with blades 21 for rising, falling and turning.
