Description

Technical Field

[0001] The utility model belongs to the technical field of laser detection and protection, and in particular relates to a laser absorber suitable for testing lasers of various powers. Background Art

[0002] A laser is a device used to emit laser light. Lasers are typically activated during both production and testing. Because high-energy lasers are highly destructive, a laser absorber is required to effectively absorb the laser light to prevent potential damage to personnel and equipment.

[0003] Currently, common laser absorbers consist of an absorber base and a reflective axle. The absorber base contains an absorption cavity, which is located within the reflective axle. Heat sinks are also installed on the absorber base. When laser light enters the absorption cavity, it is reflected by the reflective axle onto the inner wall of the absorption cavity. The inner wall of the absorption cavity reflects and absorbs the laser light, effectively absorbing it. This structure improves the heat dissipation performance of the absorber base by providing a heat sink. However, the poor heat dissipation performance of the heat sink limits the heat dissipation capability of the laser absorber, making it unsuitable for medium- and high-power lasers.

A water-cooling channel 32 is provided in the water-cooling seat body 31, and the water-cooling channel 32 is used to communicate with the water pump.

[0043] In some embodiments of the present application, the cover body 11 is a circular structure, and the through hole 111 is located in the middle of the cover body 11 and is coaxially arranged with the cover body 11 .

[0044] In some embodiments of the present application, the base 13 is a square base, and the width of the base 13 is greater than the outer diameter of the cylinder 12 .

[0045] In some embodiments of the present application, the base 13 , the cylinder 12 and the reflective cone 14 are an integrated structure.

[0046] In some embodiments of the present application, the reflective cone 14 is a conical structure, the bottom of the conical structure is connected to the base 13, the top of the conical structure faces the through hole 111 of the cover 11, and the axis of the reflective cone 14 and the axis of the through hole 111 are on the same straight line.

[0047] In some embodiments of the present application, a plurality of annular grooves 121 are provided on the outer circumferential surface of the cylinder 12 . The plurality of annular grooves 121 are sequentially arranged along the axial direction of the cylinder 12 , and the annular grooves 121 and the cylinder 12 are coaxially arranged.

[0048] In some embodiments of the present application, when laser light is incident on the inner wall of the cylinder 12, the inner wall of the cylinder 12 can reflect and absorb the laser light multiple times, thereby achieving effective absorption of the laser light. Furthermore, the inner wall of the cylinder 12 can be provided with threads. Thus, an uneven structure can be formed on the inner wall of the cylinder 12, thereby improving the absorption effect of the cylinder 12 on the laser light, and thereby improving the absorption effect of the laser absorber on the laser light.

[0049] In some embodiments of the present application, the sleeve 21 and the cylinder 12 are coaxially arranged.

[0050] In some embodiments of the present application, the water-cooling seat body 31 and the base 13 can be connected by screw connection, bolt connection or clamping.

[0051] In some embodiments of the present application, the water inlet and the water outlet of the water cooling channel 32 may be connected to a water pump to form circulating cooling of the cooling water.

[0052] In the above scheme of the present application, the laser absorber includes a natural cooling component 1, an air cooling component 2 and a water cooling component 3. The natural cooling component 1 includes a cover 11, a cylinder 12 and a base 13. The cover 11 and the base 13 are respectively connected to both sides of the cylinder 12. A reflection cone 14 is provided in the cylinder 12. A through hole 111 is provided on the cover 11. The reflection cone 14 and the through hole 111 are arranged opposite to each other. An annular groove 121 is provided on the outer peripheral surface of the cylinder 12; the air cooling component 2 includes a sleeve 21, which is sleeved on the outside of the cylinder 12. There is a heat dissipation gap between the inner wall of the sleeve 21 and the outer wall of the cylinder 12. An air inlet 22 and an air outlet 23 are provided on the sleeve 21. The air inlet 22 is used to connect with the air compressor; the water cooling component 3 includes a water cooling seat 31, which is detachably connected to the lower surface of the base 13. A water cooling channel 32 is provided in the water cooling seat 31, and the water cooling channel 32 is used to connect with the water pump. With this structure, first, when laser light is incident on the reflective cone 14 through the through-hole 111 in the cover 11, it is reflected from the surface of the reflective cone 14 to the inner wall of the cylinder 12, thereby achieving effective absorption of the laser light. Second, the presence of an annular groove 121 on the outer circumference of the cylinder 12 increases the heat dissipation area of the outer circumference of the cylinder 12, thereby improving the heat dissipation performance of the cylinder 12 and, in turn, the heat dissipation performance of the laser absorber. Simultaneously, gas generated by the air compressor can flow through the air inlet 22 into the heat dissipation gap between the sleeve 21 and the cylinder 12 and out through the air outlet 23, thereby enabling the cylinder 12 to be air-cooled by the air-cooling assembly 2, improving the heat dissipation performance of the cylinder 12 and the laser absorber. Furthermore, when the water-cooled seat 31 is connected to the base 13, cooling water can be pumped into the water-cooling channel 32 by a water pump, enabling water cooling of the base 13 and the cylinder 12, further improving the heat dissipation performance of the laser absorber. The present application provides an annular groove 121 on the outer peripheral surface of the cylinder 12, an air cooling component 2 and a water cooling component 3, which can improve the heat dissipation performance of the laser absorber, making the laser absorber suitable for medium and high power lasers, thereby improving the scope of application of the laser absorber.

[0053] It is understandable that the laser absorber in the embodiment of the present application can be applied to a variety of lasers with different powers. For lasers with different powers, the laser absorber in the embodiment of the present application can adopt different heat dissipation structures and heat dissipation methods.

[0054] Specifically, in this embodiment, the laser absorber using the natural cooling component 1, the air cooling component 2 and the water cooling component 3 has four different heat dissipation structures and heat dissipation methods. Figures 2 to 4 As shown, the first heat dissipation structure is to use the natural cooling component 1 alone. In this way, the laser absorber can be applied to medium and low power lasers, such as 1W~100W. Figure 11 As shown, the second heat dissipation structure is the use of natural cooling components 1 and air cooling components 2. In this way, by utilizing the combined effect of natural cooling and air cooling, the laser absorber can be applied to medium and high power lasers, such as 50W~100kW. Figure 10 As shown, the third heat dissipation structure is the use of natural cooling components 1 and water cooling components 3. In this way, the combined effect of natural cooling and water cooling makes the laser absorber suitable for medium and high power lasers. Figure 1 As shown, the fourth heat dissipation structure is the combination of a natural cooling component 1, an air cooling component 2 and a water cooling component 3. In this way, by utilizing the combined effects of natural cooling, air cooling and water cooling, the laser absorber can be suitable for medium and high power lasers.

[0055] In some embodiments of the present application, Figure 9 、 Figure 12 、 Figure 13 、 Figure 14 and Figure 15 As shown, the laser absorber also includes a height adjustment component 4; the height adjustment component 4 includes a column 41, an adjustment member 42 and a locking member. The adjustment member 42 is sleeved on the column 41 and slides relative to the column 41. The locking member is used to lock the adjustment member 42 on the column 41. The adjustment member 42 is used to connect to the natural cooling component 1 or the water cooling component 3. With this structure, when the adjustment member 42 slides on the column 41, it can drive the natural cooling component 1 or the water cooling component 3 to move along the height direction of the column 41. When the adjustment member 42 is locked to the column 41 by the locking member, the natural cooling component 1 or the water cooling component 3 can be fixed at different positions on the column 41, thereby being able to adjust the height of the natural cooling component 1, so that the laser absorber can meet the testing requirements of different heights.

[0056] It is understandable that in the embodiment of the present application, the laser absorber using the natural cooling component 1, the air cooling component 2, the water cooling component 3 and the height adjustment component 4 has four different connection structures and connection methods. Figure 12 As shown, the first connection structure is that the natural cooling component 1 is connected to the adjustment member 42 in the height adjustment component 4. Figure 13 As shown, the second connection structure is that the natural cooling component 1 is connected to the water cooling component 3, and the water cooling component 3 is connected to the adjustment member 42 in the height adjustment component 4. Figure 14As shown, the third connection structure is the use of the natural cooling component 1 and the air cooling component 2, and the natural cooling component 1 is connected to the adjustment member 42 in the height adjustment component 4. Figure 15 As shown, the fourth connection structure is the coordinated use of the natural cooling component 1 , the air cooling component 2 and the water cooling component 3 , and the water cooling component 3 is connected to the adjustment member 42 in the height adjustment component 4 .

[0057] In some embodiments of the present application, the adjusting member 42 includes a transverse plate, a first longitudinal plate, and a second longitudinal plate. The first ends of the first longitudinal plate and the second longitudinal plate are both connected to the transverse plate, and there is a gap between the first longitudinal plate and the second longitudinal plate. The transverse plate is used to connect to the natural cooling component 1 or the water cooling component 3. The transverse plate is provided with a first arcuate groove, the first longitudinal plate is provided with a second arcuate groove, and the second longitudinal plate is provided with a third arcuate groove. The first arcuate groove, the second arcuate groove, and the third arcuate groove together form a through-hole, and the column 41 is inserted into the through-hole. The locking member includes a bolt, the second end of the first longitudinal plate is provided with a connecting hole, and the second end of the second longitudinal plate is provided with a threaded hole. The bolt extends through the connecting hole and is threadedly connected to the threaded hole. With this structure, when the bolt is screwed in the threaded hole, it can apply pressure to the first longitudinal plate and the second longitudinal plate, so that the first longitudinal plate and the second longitudinal plate can clamp the column 41, thereby allowing the adjusting member 42 to be locked on the column 41.

[0058] In some embodiments of the present application, Figure 2 、 Figure 3 and Figure 4 As shown, the cover 11 includes a base plate and an annular plate. The annular plate is disposed on the lower surface of the base plate and is sleeved within the cylindrical body 12. The through hole 111 is located on the base plate. The outer circumferential surface of the annular plate is provided with an external thread, and the inner wall of the cylindrical body 12 is provided with an internal thread. The annular plate and the cylindrical body 12 are threadedly connected. With this structure, when the annular plate and the cylindrical body 12 are threadedly connected, the reliability of the connection between the annular plate and the cylindrical body 12 can be improved.

[0059] In some embodiments of the present application, the bottom plate is a circular plate with a diameter greater than the outer diameter of the cylinder 12. The upper end surface of the sleeve 21 abuts against the bottom plate, and the lower end surface abuts against the base 13. With this structure, when the cover 11 rotates relative to the cylinder 12, the sleeve 21 can be pressed tightly between the cover 11 and the base 13, thereby improving the reliability and sealing of the installation of the air-cooling assembly 2.

[0060] In some embodiments of the present application, an annular groove is provided on the base plate, the annular groove and the base plate are coaxially arranged, and the upper end of the sleeve 21 is located in the annular groove.

[0061] In some embodiments of the present application, Figure 5 and Figure 6As shown, the sleeve 21 is provided with two air inlet holes 22 and one air outlet hole 23, which are evenly distributed along the circumference of the sleeve 21. With this structure, air is simultaneously taken in through the two air inlet holes 22 and discharged through the single air outlet hole 23, which can increase the pressure of the cooling gas in the heat dissipation gap, thereby optimizing the flow path of the cooling gas and making the cooling gas distribution more even, thereby improving the heat dissipation effect of the air-cooled component 2.

[0062] In some embodiments of the present application, Figure 7 and Figure 8 As shown, the water cooling channel 32 includes two longitudinal channels and one transverse channel, both of which are connected to the transverse channel. With this structure, cooling water is transported through the two longitudinal channels and one transverse channel, which can optimize the flow path of the cooling water and improve the cooling effect of the water cooling component 3.

With this structure, the base 13 can be connected to different components through the first mounting holes 131 and the second mounting holes 132, thereby being suitable for different installation environments.

[0064] In some embodiments of the present application, the first mounting hole 131 may be a threaded hole with a nominal diameter of 3 mm, and the second mounting hole 132 may be a threaded hole with a nominal diameter of 6 mm.

[0066] In some embodiments of the present application, a threaded hole is further provided on the bottom surface of the base 13. When the natural cooling component 1 is installed on the height adjustment component 4, the adjustment member 42 can be connected to the base 13 by screws.

[0067] In some embodiments of the present application, Figure 8 As shown, the upper surface of the water-cooling base 31 is provided with a plurality of third mounting holes 33, which correspond one-to-one with the plurality of first mounting holes 131. With this structure, the water-cooling base 31 and the base 13 can be connected using bolts and nuts. During connection, the bolts extend through the third mounting holes 33 and the first mounting holes 131 in sequence and engage with the nut threads, thereby securing the water-cooling base 31 to the base 13.

[0068] In some embodiments of the present application, the water-cooling seat 31 is a square seat, and four third mounting holes 33 are provided. The four third mounting holes 33 are located at the four top corners of the water-cooling seat 31, and the four third mounting holes 33 correspond one-to-one to the four first mounting holes 131.
