[0025] A water inlet pipe 3 is connected to the surface of the connecting frame 12, and a connecting pipe 10 is provided at the end of the water inlet pipe 3. Ventilation nets 13 are provided on both sides of the connecting frame 12. The connecting pipe 10 is arranged between the two ventilation nets 13. Through the setting of the ventilation net 13, it is convenient to blow air to the connecting pipe 10 through the cooling fan 11, and then transmit the wind flow through the ventilation net 13. A water outlet pipe 4 is provided at the end of the connecting pipe 10. The connecting pipe 10 is S-shaped and evenly distributed inside the connecting frame 12. The water inlet pipe 3 and the water outlet pipe 4 both penetrate the side of the installation frame 2 and the connecting frame 12 and are connected to the connecting pipe 10. The coolant enters the connecting pipe 10 through the water inlet pipe 3 and is discharged through the water outlet pipe 4, thereby completing the water cooling of the device. A connecting frame 14 is provided on the surface of the connecting frame 12. Through the setting of the connecting frame 14, it is convenient to install the wind collecting bucket 15 A wind collecting scoop 15 is provided on the surface of the connecting frame 14. The diameter of the wind collecting scoop 15 gradually increases from the end close to the ventilation pipe 16 to the other end. The end diameter of the wind collecting scoop 15 close to the ventilation net 13 is larger. Since the diameter of the wind collecting scoop 15 changes from large to small, the air flow rate will become faster, thereby improving the heat dissipation effect of the laser head body 1. A ventilation pipe 16 is provided on the surface of the wind collecting scoop 15. The length of the ventilation pipe 16 is relatively short. Through the setting of the ventilation pipe 16, the rapid airflow coming out of the wind collecting scoop 15 is guided and transmitted quickly. The wind collecting scoop 15 and the ventilation pipe 16 are arranged in a linear array on the surface of the connecting frame 12. A mounting plate 17 is provided on the surface of the connecting frame 12. A mounting bolt 18 is provided on the surface of the mounting plate 17. Through the setting of the mounting plate 17 and the mounting bolt 18, it is convenient to install the connecting frame 12 inside the mounting frame 2.

[0026] The coolant enters the connecting pipe 10 through the water inlet pipe 3 and is discharged through the water outlet pipe 4. The cooling water is circulated in the connecting pipe 10, and the temperature is quickly reduced during the water flow. The cooling fan 11 is turned on, and the cold air is blown toward the laser head body 1 through the cooperation of the cooling fan 11. At the same time, through the setting of the wind collecting scoop 15, the end of the wind collecting scoop 15 close to the ventilation network 13 has a larger diameter. Since the diameter of one end of the wind collecting scoop 15 is smaller than the diameter of the other end, when the cold air flows through the wind collecting scoop 15 and the ventilation pipe 16, the flow rate of the airflow will become faster, and the heat in the mounting frame 2 and the air flow are realized through the heat dissipation port 8, so that the laser head body 1 can achieve rapid forced heat dissipation, avoid damage to internal components, and ensure the service life of the laser head body 1. Specific embodiment 2:

[0028] Under the premise of satisfying the above structure, heat dissipation fins can be arranged on the surface of the mounting frame 2 to further dissipate heat from the laser head body 1, thereby improving the heat dissipation effect of the device and ensuring the service life of the laser head body 1.

[0029] In summary:

[0030] 1. The cooling fan 11, the connecting pipe 10, the wind collecting scoop 15 and the ventilation pipe 16 are used to circulate the cooling water in the connecting pipe 10, and the water is quickly cooled during the flow. The cooling fan 11 cooperates with the cooling fan 11 to blow the cold air toward the laser head body 1. At the same time, through the setting of the wind collecting scoop 15, since the diameter of one end of the wind collecting scoop 15 is smaller than the diameter of the other end, when the cold air flows through the wind collecting scoop 15 and the ventilation pipe 16, the flow rate of the air flow will become faster, so that the laser head body 1 can achieve rapid forced heat dissipation, avoid damage to internal components, and ensure the service life of the laser head body 1.
