Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of water cooling heads, in particular to a water cooling head for a high-power laser cutter. Background Art
[0002] The water cooling head plays a very important role in the laser cutter. It is one of the key components used to cool the laser cutter. It absorbs the heat generated by the laser through circulating water, keeps the temperature of the laser within a safe range, can effectively reduce the temperature of the laser, prevent the laser from overheating and damage, and can also improve the stability and accuracy of laser cutting.
[0003] The main requirements for the water cooling head of the laser cutter include: high temperature resistance. The laser cutter will generate high temperature when working. The water cooling head needs to be able to withstand the high temperature environment to ensure the stable operation of the laser head; efficient heat dissipation. The water cooling head needs to have good heat dissipation performance and be able to quickly transfer heat to the cooling water to ensure that the laser head does not overheat; corrosion resistance. The water cooling head needs to be corrosion-resistant because the cooling water may contain various chemicals. It is necessary to ensure that the water cooling head will not be damaged by corrosion; stability. The water cooling head needs to have good stability and be able to work stably for a long time without malfunctioning due to temperature changes or other factors.
[0004] The water cooling heads of high-power laser cutters and low-power laser cutters have the same requirements for corrosion resistance and stability, but the main difference lies in their heat dissipation capacity and high temperature resistance. High-power laser cutters generate more heat, and require more powerful water cooling heads to effectively dissipate heat to avoid overheating and damage to the equipment; high-power laser cutters generate higher temperatures when working, so the water cooling heads need to have higher high temperature resistance to ensure that there will be no failures during long-term high-power operation.
[0005] However, in the prior art, the water-cooling head of a high-power laser cutter has limited heat dissipation effect and cannot effectively dissipate heat quickly, resulting in excessive temperature of the equipment, affecting the stability and working efficiency of the equipment. Long-term high-temperature operation can cause the water-cooling head to deform, age or even be damaged, thereby affecting the normal operation of the equipment. In addition, there is also the disadvantage of frequent maintenance and replacement, which is inconvenient to replace. Utility Model Content
