Introduction of cooling system of UV laser marking machine

UV UV laser marking machine consists of UV laser, power supply system, galvanometer field mirror scanning system, marking software, computer and cooling system. Every part is essential, especially the cooling system, also known as The chiller is mainly used to control the temperature of the UV laser marking machine, so as to avoid equipment failure caused by excessive temperature.

At present, the cooling system of UV laser marking machine mainly includes water cooling, air cooling and water cooling and air cooling integrated system, among which water cooling is the most widely used. The working principle is:

1. The chiller of the UV laser marking machine generally has a filter, which can effectively filter out the obvious particle impurities in the water and maintain the laser pump cavity. clean and prevent the possibility of water plugging.

2. The chiller uses pure water or deionized water, which is more conducive to the direct entry of the pump light source into the laser material, which can produce a better laser mode.

3. The chiller of UV laser marking machine is generally equipped with a water pressure pressure gauge, which can clearly know what the water pressure in the laser waterway is.

4. The chiller adopts imported compressor, the water tank and water pump are made of stainless steel, and the heat transfer coil is also used Stainless steel material, which can completely ensure the stable operation of the chiller, the cooling effect is very good, and the temperature accuracy can be within 1 °C. The smaller the controlled temperature, the less the laser is affected by the temperature. The temperature control accuracy is ±0.3℃~±1℃.

5. The chiller of UV laser marking machine is generally powered by 220V household electricity instead of 380V three-phase electricity, which is more conducive to the versatility of the equipment.

6. The chiller has flow protection. When the water flow is less than the set value, there is a signal alarm, which can be used to protect the laser and related devices to be dissipated. The laser chiller includes the advanced functions of input and output control equipment switch and cooling water flow, high and low temperature alarm. Compared with the same kind, the performance of the UV UV laser marking machine chiller is more stable and durable, and it is especially excellent in energy saving and environmental protection.

7. The chiller has temperature protection. If the temperature is not suitable, a signal alarm will also appear.

8. The chiller of the UV laser marking machine has the functions of intelligent temperature control and manual adjustment of the water temperature. In the intelligent temperature control mode, the chiller adjusts itself according to the change of the ambient temperature. Cooling water temperature without manual monitoring.
