[0002] Although there are many types of lasers, the manufacturing principles are basically the same. Most of them are composed of three parts: the excitation system, the laser material and the optical resonator. The excitation system is a device that generates light, electricity and chemical energy. The excitation system provides energy, so that most of the electrons in the laser material absorb energy and jump to the outer orbit of the atom, creating conditions for the subsequent emission of lasers. Laser material is a material that can generate lasers. Such as ruby, neodymium glass, neon, nitrogen, carbon dioxide, metal vapor, semiconductors, organic dyes, etc. The function of the optical resonator is to enhance the brightness of the output laser, adjust and select the wavelength and direction of the light.

[0019] Preferably, a heat conducting block is provided on the laser cutting nozzle, and the heat conducting block is threadedly connected to the laser housing.

[0020] By adopting the above technical solution, heat is transferred through the heat conductive block to transfer the heat of the laser cutting nozzle to the laser housing for heat dissipation, thereby reducing the possibility of heat accumulation in the laser cutting nozzle and improving the heat dissipation of the laser.

The laser cutting nozzle 2 is detachably connected to the laser housing 1. A laser module is installed in the laser housing 1. A heat sink 11 is installed on the laser housing 1. There is a gap between the heat sink 11 and the laser housing 1. A plurality of heat dissipation holes 12 are respectively opened on the heat sink 11. The plurality of heat dissipation holes 12 are evenly distributed on the heat sink 11. The plurality of heat dissipation holes 12 are arranged in a tapered shape from one end away from the laser housing 1 to the end close to the laser housing 1.

[0033] Reference Figure 1-Figure 3 By adding the heat sink 11, the heat of the laser housing can be conducted to achieve the purpose of heat dissipation of the laser housing. When the air flows through the heat dissipation hole 12, the air flow flows from the large end of the heat dissipation hole 12 to the small end of the heat dissipation hole 12. Since the air mass cannot be accumulated in large quantities, it is accelerated to flow through the heat dissipation hole 12, resulting in an increase in wind speed, thereby improving the heat dissipation of the laser.

[0036] Reference Figure 1-Figure 3 A plurality of heat dissipation grooves 15 are respectively provided on the plurality of heat conducting plates 14, and the plurality of heat dissipation grooves 15 are evenly distributed along the circumference of the heat conducting plates 14. The heat dissipation grooves 15 are used to increase the heat dissipation area of ​​the heat conducting grooves, so that the heat conduction is dissipated during the heat conduction process of the laser housing 1, so as to improve the heat dissipation performance of the radiator.

[0037] Reference Figure 1-Figure 3 A ventilation channel 16 is formed between two adjacent heat conducting plates 14, and both ends of the ventilation channel 16 penetrate the laser housing 1. This allows air to circulate between the heat sink 11 and the laser, reducing the possibility of heat accumulation between the heat sink 11 and the laser, thereby improving the heat dissipation of the laser.

[0038] Reference Figure 2-Figure 4A plurality of heat pipes 17 are fixedly connected to the laser housing 1, and the ends of the heat pipes 17 away from the laser housing 1 are respectively abutted against the high power consumption parts of the laser module. The heat pipes 17 are used for heat transfer to dissipate the high power consumption parts of the laser, thereby reducing the possibility of overheating of the high power consumption parts of the laser, thereby improving the heat dissipation of the laser and enabling the laser to operate at high power.
