Description

Technical Field

[0001] The utility model belongs to the technical field of lasers, and in particular relates to an air cooling component for lasers. Background Art

[0002] A laser is a device that can produce high-intensity, coherent, monochromatic and directional light beams. Its working principle is based on stimulated radiation and optical resonance. It converts input energy into light energy through the stimulated radiation process, and realizes laser amplification through light feedback and amplification. The laser has monochromaticity, coherence and good directivity. The laser head at the end of the laser is the key component in the laser responsible for controlling and generating the laser beam. It is usually composed of laser diodes, optical lenses, reflectors and other components.

[0003] When the laser emits a laser through the laser head, the temperature of the laser head will rise rapidly. After the laser head is used for a long time, the surface temperature will exceed the safe temperature that the laser head can withstand, so that the service life of the laser head will be greatly reduced. In order to solve this problem, in the prior art, one or more fans are usually arranged around the laser head to cool the laser head. However, when the laser head heats up, the surrounding temperature will also rise. Therefore, the wind blown by the fan is still hot air, so that the cooling effect on the laser head is not ideal. In view of this, the present utility model is specially proposed. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide an air-cooling component for a laser that can overcome the above problems or at least partially solve the above problems.

[0005] In order to solve the above technical problems, the basic concept of the technical solution adopted by the utility model is: a wind-cooling component for a laser, including a support plate, which is sleeved on the laser body near the laser head, and also includes: a hair dryer, which is symmetrically fixedly connected to the two sides of the lower end of the support plate and is located on both sides of the laser head on the laser body; a hair dryer, which is installed in the hair dryer near the air outlet; an annular refrigeration water supply tank, which is fixedly installed on the support plate; a hot water exchange pipe, which is installed in the hair dryer near the air inlet, and the water inlet and outlet of the hot water exchange pipe are respectively connected with the water outlet and the water return port of the annular refrigeration water supply tank.

[0006] In order to facilitate more comprehensive air cooling of the laser head, the support plate is further rotatably connected to the laser body through a rotating bearing, a motor is installed on the laser body, a gear is fixedly connected to the output end of the motor, and a gear ring meshing with the gear is fixedly connected to the annular refrigeration water supply tank.

[0007] In order to further improve the heat dissipation and cooling effect of the laser head, further, a plurality of heat dissipation fins are inserted into the laser head on the laser body at equal distances in a circle.

[0008] In order to facilitate the purification of harmful gases generated when the laser head emits laser, the support plate is further a cross-shaped plate, and suction cylinders are symmetrically fixedly connected to the cross-shaped plate. The suction cylinders are located on both sides of the laser head on the laser body, and are vertically distributed between the two suction cylinders and the two blowers. A suction fan is installed near the air inlet in the suction cylinder, and an activated carbon filter plate is installed near the air outlet in the suction cylinder.

[0009] In order to facilitate the rapid disassembly and assembly of the activated carbon filter plate, further, the activated carbon filter plate is detachably connected to the suction tube via threads, and a handle is installed on the activated carbon filter plate.

[0010] In order to make it easier for the vacuum fan to remove as much harmful gas as possible generated when the laser head emits laser, further, a protective cover is fixedly connected on the support plate between the two blower cylinders and the two suction cylinders. The protective cover is sleeved on the outer side of the laser head on the laser body, and a through opening connected to the blower cylinder and the suction cylinder is opened on the protective cover.

[0011] After adopting the above technical scheme, the utility model has the following beneficial effects compared with the prior art: compared with the prior art method of only using a single fan to blow air to dissipate heat for the laser head on the laser, the utility model uses a support plate, an annular refrigeration water supply tank, and symmetrically arranged hair dryers, hair dryers, hot water exchange pipes and other components. The air cooling component can not only increase the air volume blown to the surface of the laser head, but also make the temperature of the gas blown to the surface of the laser head lower, thereby effectively improving the heat dissipation effect of the laser head and effectively ensuring the service life of the laser head.

[0012] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0020] Embodiment 1:

[0021] Reference Figure 1-Figure 4 A laser air cooling assembly includes a support plate 201, which is sleeved on a laser body 1 near a laser head, and also includes: a hair dryer 202, which is symmetrically fixedly connected to both sides of the lower end of the support plate 201 and is located on both sides of the laser head on the laser body 1; a hair dryer 203, which is installed in the hair dryer 202 near the air outlet; an annular refrigeration water delivery box 204, which is fixedly installed on the support plate 201; a hot water exchange pipe 205, which is installed in the hair dryer 202 near the air inlet, and the water inlet and outlet of the hot water exchange pipe 205 are respectively connected with the water outlet and the water return port of the annular refrigeration water delivery box 204, such as Figure 1 As shown, the annular refrigeration water delivery tank 204 is provided with a water pump for delivering water into the hot water exchange pipe 205 , and a semiconductor refrigeration plate for cooling the water in the annular refrigeration water delivery tank 204 .

[0022] When the laser body 1 emits laser through the laser head, in order to ensure that the laser head is used within the specified temperature range and avoid damage due to high temperature, the hair dryer 203 and the water pump and semiconductor refrigeration plate in the annular refrigeration water delivery tank 204 can be started synchronously when the laser head is running. Then the water pump in the annular refrigeration water delivery tank 204 will deliver the water cooled by the semiconductor refrigeration plate into the hot water exchange pipe 205, and then the water in the hot water exchange pipe 205 will flow back into the annular refrigeration water delivery tank 204 through the water outlet, so that the water will circulate in the hot water exchange pipe 205 to ensure that the temperature of the water in the hot water exchange pipe 205 is always Finally, the temperature is kept within a relatively low range to ensure the cooling effect on the air. When the hair dryer 203 is working, the external gas is sucked into the hair dryer 202. When the gas contacts the hot water exchange pipe 205, the gas will exchange heat with the hot water exchange pipe 205. Then, the gas blown out by the hair dryer 203 will have a relatively low temperature. When the gas with a relatively low temperature contacts the laser head, the laser head can be better dissipated and cooled, thereby effectively improving the cooling effect on the laser head. In addition, by symmetrically arranging two groups of hair dryers 203 on both sides of the laser head, the air-cooling effect on the laser head can be further improved, thereby effectively ensuring the service life of the laser head.

[0023] Embodiment 2:

[0024] Reference Figure 1-Figure 4 , a wind cooling component for a laser, which is basically the same as Example 1, and further: a support plate 201 is rotatably connected to a laser body 1 through a rotating bearing 2, a motor 3 is installed on the laser body 1, and a gear 301 is fixedly connected to the output end of the motor 3, and a gear ring 302 meshing with the gear 301 is fixedly connected to the annular refrigeration water delivery box 204. When the hair dryer 203 is started to dissipate heat and cool the laser head, the motor 3 can be started at this time, and the motor 3 will drive the gear 301 to rotate, and the gear 301 will drive the annular refrigeration water delivery box 204 to rotate with the cooperation of the gear ring 302, so that the hair dryer 203 can be driven by the support plate 201 to rotate around the laser head, so as to facilitate more comprehensive air cooling of the laser head, and further improve the heat dissipation and cooling effect of the laser head.

[0025] It should be noted that in order to avoid entanglement of the annular cooling water supply tank 204, the water pump in the hair dryer 203, the semiconductor cooling plate and the electrical wires used in the blower motor, the motor 3 can control the gear 301 to rotate forward and reverse in a certain period, so that the support plate 201 rotates forward one circle and then flips over one circle. This repetition can not only ensure the comprehensiveness of the blowing of the laser head, but also avoid the problem of entanglement of the electrical wires.

[0026] It should be further noted that, in actual use, the gear 301 and the gear ring 302 can be a bevel gear and a bevel gear ring, so as to ensure that the gear 301 can rotate smoothly on the gear ring 302 and ensure that the support plate 201 rotates normally.

[0027] A plurality of heat dissipation fins 206 are equidistantly connected to the laser head on the laser body 1 in a circular shape. Through the setting of the heat dissipation fins 206, the heat generated by the laser head can be quickly guided to the outside of the laser head, so that when the hair dryer 203 blows cold air to the laser head, the laser head can be quickly cooled, further improving the heat dissipation and cooling effect of the laser head.

[0028] Embodiment 3:

[0029] Reference Figure 1-Figure 4 , a wind cooling component for a laser, which is basically the same as Example 2, and further: the support plate 201 is a cross-shaped plate, and the cross-shaped plate is symmetrically fixedly connected with suction cylinders 207, the suction cylinders 207 are located on both sides of the laser head on the laser body 1, and the two suction cylinders 207 are vertically distributed with the two blowers 202. A suction fan 208 is installed near the air inlet in the suction cylinder 207, and an activated carbon filter plate 209 is installed near the air outlet in the suction cylinder 207. When the hair dryer 203 is started to blow cold air to the laser head for heat dissipation and cooling, the suction fan 208 is started synchronously at this time, and the suction fan 208 will quickly suck the harmful gas generated when the laser head emits the laser into the suction cylinder 207, and purify it through the activated carbon filter plate 209, so as to reduce the probability of allergic reaction or discomfort in the respiratory tract such as the lungs after being absorbed by the human body.

[0030] The activated carbon filter plate 209 is detachably connected to the suction tube 207 via threads. A handle is installed on the activated carbon filter plate 209. By threading the activated carbon filter plate 209 into the suction tube 207, when the activated carbon filter plate 209 is saturated or blocked and needs to be replaced, the staff can use the handle to quickly take out the activated carbon filter plate 209 from the suction tube 207 and replace it with a new activated carbon filter plate 209, which provides convenience for the staff to disassemble and assemble the activated carbon filter plate 209.

[0031] A protective cover 2010 is fixedly connected between the two blowers 202 and the two suction tubes 207 on the support plate 201. The protective cover 2010 is sleeved on the outer side of the laser head on the laser body 1. A through hole connected to the blowers 202 and the suction tubes 207 is opened on the protective cover 2010. By arranging the protective cover 2010 on the outer side of the laser head on the laser body 1, the suction fan 208 can suck the harmful gas generated when the laser head emits the laser into the suction tube 207 as much as possible, and adsorb and purify it through the activated carbon filter plate 209, further reducing the probability of allergic reaction or discomfort in the respiratory tract such as the lungs after being absorbed by the human body.
