[0020] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0021] This invention provides a high-power water-cooled absorption box that can effectively absorb residual laser light generated by a laser system, thereby ensuring the environmental safety of the laser system; it can also reduce the heat inside the laser system and improve the working stability of the laser.

[0022] See Figures 1 to 2 The high-power water-cooled absorption box includes a box body 1, an absorption cylinder 2, a cone-shaped absorption body 3, a sealing plate 4, a window plate 5, an inlet connector 7, and an outlet connector 8.

[0023] The top of the absorption cylinder 2 is fixedly fitted with a box body 1. For easy assembly, the absorption cylinder 2 and the box body 1 are connected by threads. A window piece 5 is fixedly fitted inside the box body 1. To facilitate the replacement of the window piece 5, a pressure ring 6 is provided on the outside of the window piece 5, which presses the window piece 5 into the inside of the box body 1.

[0024] The outer wall of the absorption cylinder 2 has multiple annular heat dissipation grooves to improve the heat dissipation capacity of the absorption cylinder 2; the cone absorber 3 is coaxially fixed inside the absorption cylinder 2. For easy assembly, the absorption cylinder 2 and the cone absorber 3 are connected by screws, forming a space for multiple laser reflections between the surface of the cone absorber 3 and the inner wall of the absorption cylinder 2.

[0025] The surface of the cone absorber 3 is cone-shaped with an included angle of less than 90 degrees. The cone absorber 3 has a water-cooling tank inside; a sealing plate 4 is fixedly installed at the bottom of the cone absorber 3 to seal the water-cooling tank; the sealing plate 4 has a water inlet connector 7 connected to one end of the water-cooling tank and a water outlet connector 8 connected to the other end of the water-cooling tank.

[0026] In this invention, the absorber cylinder 2 and the cone absorber 3 are made of metal or ceramic materials and are used to absorb laser energy, convert it into heat energy and dissipate it.

[0027] The working principle of the high-power water-cooled absorption box provided by this utility model is as follows:

[0028] Inside the housing 1, a window plate 5 is installed. The laser passes through the window plate 5 and is incident on the cone absorber 3. Most of the laser energy is absorbed by the cone absorber 3, and a small portion of the laser energy is reflected by the surface of the cone absorber 3 to the absorption cylinder 2. The laser energy reflected to the absorption cylinder 2 is absorbed and converted into heat energy, which is dissipated into the air through the annular heat dissipation groove on the outer surface of the absorption cylinder 2. A small portion of the laser energy is reflected by the absorption cylinder 2 to the surface of the cone absorber 3. Therefore, a small amount of laser energy that is not converted into heat energy is continuously reflected between the cone absorber 3 and the absorption cylinder 2, and is eventually absorbed by the cone absorber 3 or the absorption cylinder 2, thus achieving effective and complete absorption of the laser energy.

[0029] In the above process, the cone absorber 3 absorbs the laser and converts it into heat energy. The cooling water entering through the inlet connector 7 absorbs the heat and discharges it from the outlet connector 8. By using cooling water, the heat dissipation efficiency of the cone absorber 3 is improved.

[0030] During the above process, the annular heat dissipation grooves on the outer surface of the absorption cylinder 2 improve the heat dissipation efficiency of the absorption cylinder 2.

[0031] In the above process, by setting the window plate 5, particulate matter formed by laser reflection onto the cone absorber 3 and the absorption cylinder 2 can be prevented from being dispersed into the laser system, thus playing an isolation role.

[0032] The high-power water-cooled absorption box provided by this utility model has the following advantages:

[0033] 1) It can safely and effectively absorb the residual laser generated by the laser system, ensuring the environmental safety of the laser system;

[0034] 2) It can reduce the heat inside the laser system and improve the working stability of the laser.

[0035] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
