The cooling system is one of the important components of laser welding machines. If the cooling system malfunctions, it can cause the equipment to stop working, and in severe cases, it may even lead to crystal rod explosions and other situations. It can be seen from this that the cooling system of laser welding machines is important.
At present, the cooling system of laser welding machines mainly includes water cooling, air cooling, and water cooling in one. Among them, water cooling is widely used. Its working principle is as follows:
1. The chiller unit of laser welding equipment generally has a filter that can effectively filter out obvious particle impurities in the water, maintain the cleanliness of the laser pump chamber, and prevent the possibility of water blockage.
2. The chiller uses pure water or deionized water, which is more conducive to directly injecting the pump light source into the laser material, and can produce better laser modes.
3. The chiller unit of a laser welding machine is usually equipped with a water pressure gauge, which can immediately determine the water pressure in the laser water circuit.
4. The chiller adopts an imported compressor, and both the water tank and pump are made of stainless steel material. The heat exchange coil is also made of stainless steel material, which can ensure the stability of the chiller's operation. The refrigeration effect is very good, and it can achieve temperature accuracy within 1 ℃. The temperature control is small, and the laser is minimally affected by temperature. However, we recommend setting the temperature to around 1 ℃...
5. The chiller unit of laser welding equipment is usually a 220V household power supply instead of a 380V three-phase power supply, which is more conducive to the versatility of the equipment.
6. The chiller unit is equipped with flow protection. When the water flow rate is less than the set value, there is a signal alarm, which can be used to protect the heat dissipation of the laser and related devices.
7. The chiller is equipped with temperature protection, and if the temperature is not appropriate, there will be a signal alarm.
8. There is also a water level alarm.
9. The chiller unit can achieve a series of adjustment functions, such as temperature regulation, temperature difference regulation, etc.
