Description

Technical Field

[0001] This utility model relates to the technical field of internal lens water cooling system, and in particular to a water cooling system for a laser lens. Background Technology

[0002] With the development and innovation of industrial technology, higher power lasers will be used in industrial lenses. However, the light source emitted by high power lasers will generate a lot of heat. Furthermore, due to the structural limitations of industrial lenses, it is impossible to arrange a cooling system inside the lens. If used for a long time, the temperature of the industrial lens will rise, which may cause a significant decrease in the image quality of the industrial lens, or even burn out the lens.

[0003] Water cooling boasts high heat dissipation efficiency, with a thermal conductivity more than 20 times that of traditional air cooling methods. It can solve heat dissipation problems ranging from hundreds to thousands of watts and has wide applications in industries such as lasers, military, medical, power electronics, and industrial equipment. However, most existing heat dissipation structures only cool the lens shell, transferring the lowered shell temperature to the lens, thus lowering the lens temperature. But this method cannot circulate the air inside the lens. In some sealed areas, the lens temperature remains high due to lack of air circulation, failing to achieve timely and effective heat dissipation. Utility Model Content

[0023] Example

[0024] like Figure 1 and 2As shown, a water-cooling system for a laser lens is disclosed. The laser lens includes a lower lens body 1 and an upper lens body 2 that are threaded together. The lower end face of the upper lens body 2 is provided with a positioning hole, and the depth of the positioning hole is greater than the depth of the threaded connection. The upper end of the lower lens body 1 is provided with a protrusion corresponding to the positioning hole. The protrusion sinks into the positioning hole to achieve positioning and assembly of the upper lens body 2 and the lower lens body 1. The top of the lower lens body 1 is provided with an external thread. The bottom of the upper lens body 2 is provided with an internal thread. The internal thread at the bottom of the upper lens body 2 and the external thread at the top of the lower lens body 1 cooperate to achieve a threaded connection, thereby fixing the upper lens body 2 and the lower lens body 1 together. A first lens 4 and a second lens 7 are provided inside the lower lens body 1. The water cooling system includes a sleeve 6 disposed within the lower lens body 1; the sleeve 6 is located between the first lens 4 and the second lens 7; the lower lens body 1 has a water inlet 101 and a water outlet 102 respectively on its left and right sides, with the water inlet 101 located below the water outlet 102; the lower outer surface of the sleeve 6 is provided with a first water groove 111, the upper outer surface of the sleeve 6 is provided with a third water groove 113, and the inside of the sleeve 6 is provided with a second water groove 112; the lower end of the sleeve 6 is provided with a ring of lower overflow holes 601, and the upper end is provided with a ring of upper overflow holes 602; the lower overflow holes 601 are located within the first water groove 111 and connect the first water groove 111 and the second water groove 112; the upper overflow holes 602 are located within the third water groove 112. The third water tank 113 and the second water tank 112 are connected within the tank 113; the inlet 101 is connected to the first water tank 111; the outlet 102 is connected to the third water tank 113; the first lens 4 is in contact with the water flow at the upper end of the sleeve 6, and the second lens 7 is in contact with the water flow at the lower end of the sleeve 6. The flowing water in the water path can carry away most of the heat from the first lens 4 and the second lens 7; the diameter of the inlet 101 is larger than the diameter of the outlet 102, and the number of lower overflow holes 601 is greater than the number of upper overflow holes 602. With this arrangement, the water inflow into the lower lens body 1 is greater than the water outflow, and the liquid can fill the gaps in the lower lens body 1 and expel the air in the lower lens body 1, eliminating the generation of air bubbles.

[0025] An upper sealing ring 5 is provided between the upper interior of the lower lens body 1 and the outer surface of the first lens 4; a lower sealing ring 8 is provided between the lower interior of the lower lens body 1 and the outer surface of the second lens 7. The upper sealing ring 5 prevents the upper lens body 2 and the lower lens body 1 from communicating, thus preventing the flowing water in the water channel from seeping into the interior of the upper lens body 2. The lower sealing ring 8 ensures that the liquid in the lower lens body 1 will not permeate with the liquid outside the lens.

[0026] The lower lens body 1 is also provided with an upper pressure ring 3 for fixing the first lens 4 and a lower pressure ring 9 for fixing the second lens 7. The upper pressure ring 3 is located above the first lens 4, and the lower pressure ring 9 is located below the second lens 7. The pressure at the bottom of the laser lens is relatively large, so the total height of the upper pressure ring 3 in this utility model is designed to be more than 12mm. In the high temperature and high pressure working environment, the service life of the first lens 4 and the second lens 7 in the lower lens body 1 will be reduced. The pressure ring structure can facilitate the replacement of the first lens 4 and the second lens 7, greatly improving the portability of operation.

[0027] The working principle of this utility model is as follows:

[0028] First, connect the corresponding inlet and outlet pipes to the inlet 101 and outlet 102 respectively. Start the laser lens and simultaneously start the water cooling system. Water flows from the external inlet pipe (not shown in the diagram) through the pipe connector into the inlet 101, flowing sequentially through the lower lens body 1 and submerging the overflow hole 601. When the water in the water path flows from the overflow hole 601 of the sleeve 6 into the second water tank 112 on the inner surface of the sleeve 6, the water flow area increases, and the flow velocity of the water decreases. As the flow time in the 12-channel system increases, the water absorbs the heat generated by the first lens 4 and the second lens 7, and submerges the overflow hole 602. Finally, under the pressure of the inlet 101, the flowing water rushes into the third water tank 113 through the overflow hole 602 at the upper end of the sleeve 6. At this time, due to the reduced water flow area, the flow rate of the flowing water increases, which can quickly remove the high-temperature flowing water in the second water tank 112 after absorbing the heat from the lenses. Finally, it flows from the outlet 102 into the water pipe connector and is discharged through the outlet pipe (not shown in the figure). Because the laser lens generates a lot of heat during use, causing the lens temperature to rise, the flowing water in the water path, especially the flowing water in the second water tank 112, can remove most of the heat from the first lens 4 and the second lens 7 in the lower lens body 1, resulting in a good cooling effect. This removes the heat from the lens, lowers its temperature, greatly improves the stability of the laser lens's performance, and significantly reduces the wear and tear on the first lens 4 and the second lens 7.

[0029] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
