It has the characteristics of narrow incision width, small heat-affected zone, smooth incision, high cutting speed, and can cut any shape at will. Whether it is marking or cutting, the power supply is a very important part of this type of equipment, but in the production of marking or cutting, it is very easy to generate debris and dust. In order to achieve good heat dissipation, the traditional power supply is generally made into a semi-enclosed form, such as a laser marking machine power supply in Chinese Patent No. 202120857620.2, which uses air flow to dissipate heat.

Therefore, it cannot be understood as a limitation on the present invention.

[0018] See also Figure 1 , 2 As shown, it is a schematic diagram of a preferred embodiment of the utility model. The utility model is related to a power protection structure of a laser device. Preferably, the laser device is a laser marking machine, a laser cutting machine or a laser cutting and marking integrated machine. The laser device includes a base 1, which is horizontally arranged. A mounting platform 11 is provided at a certain height from the ground on the rear side of the base 1. A power box 2 is assembled on the upper side of the mounting platform 11. The power box 2 has a bottom 21 and a peripheral wall 22 surrounding the bottom. A raised boss 23 is provided on the inner side of the bottom 21. The inside of the boss 23 is hollowed out to form a power cavity 231. The power cavity 231 is used to install electrical components. A heat dissipation hole and an aviation head interface 234 leading to the outside of the bottom 21 are provided at the inner bottom of the power cavity 231. The aviation head interface 234 realizes quick wiring so that the electrical components can be connected to the corresponding power line, data line or signal line, etc.; a heat dissipation fan 232 is installed in the heat dissipation hole to establish an air cooling system. There are two heat dissipation fans 232 in the figure, forming a one-in-one-out relationship to enhance the air flow in the power cavity 231. A groove 24 is left between the outer periphery of the boss 23 and the peripheral wall 22, and the groove 24 is connected with the water inlet 25 and the water outlet 26 provided on the power supply box 2, so as to establish a circulating water cooling system and realize water cooling of the periphery of the power supply cavity 231.

With the cooling fan 232, the air cooling effect is greatly improved. The cooling fan 232 is set downward, and debris and dust are not easy to enter the power cavity 231, reducing the dust from entering the power box. The water inlet 25 and the water outlet 26 are respectively extended to the lower side of the installation platform 11 through the joint, and the lower space of the installation platform 11 is used for disassembly and assembly, which is convenient for operation. In this embodiment, the air inlet and outlet flow direction inside the power cavity 231 is opposite to the water inlet and outlet flow direction in the groove 24, that is, the water inlet corresponds to the air outlet, and the air inlet corresponds to the water outlet, which effectively utilizes the interactive relationship to improve the heat dissipation effect. Furthermore, a heat exchange fin 233 is provided on the outer peripheral surface of the boss 23, and the heat exchange fin 233 protrudes toward the groove 24, further increasing the contact surface with the water for heat exchange, thereby improving the water cooling and heat removal effect.
