What Are The Cooling Systems of Laser Welding Machines?

Cooling system is one of the important parts of laser welding machine. If the cooling system fails, small cases will cause the equipment to stop working, and serious cases will even cause the crystal rod to explode. This shows the importance of laser welding machine cooling system. At present, the cooling system of laser welding machine mainly includes water cooling, air cooling and water cooling. Among them, water cooling is widely used. It works as follows:

The laser welding machine chiller generally has a filter, which can effectively filter out the obvious particle impurities in the water, keep the laser pump chamber clean, and prevent the possibility of water blocking. Chillers use pure or deionized water, which is more conducive to injecting the laser material directly into the pump light source and can produce better laser patterns.

The chiller of the laser welding machine is generally equipped with a water pressure meter, so you can know the water pressure in the laser water circuit at a glance. The chiller adopts imported compressor, the water tank and pump are made of stainless steel, and the heat exchange coil is also made of stainless steel.

Therefore, the stability of the chiller can be guaranteed, the refrigeration effect is very good, the temperature accuracy can reach within 1 ° C, the control temperature is small, the laser is not affected by temperature, but we recommend that the temperature should also be set at about 1 ° C.

The cooler of the laser welding machine is generally 220V household power supply, rather than 380V three-phase power supply, which is more conducive to the versatility of the equipment. Chiller with flow protection. When the water flow rate is less than the set value, a signal alarm appears and can be used to protect the heat dissipation of the laser and related equipment.

Cooler with temperature protection. If the temperature is not appropriate, a signal alarm will be issued. And water level alarms. The chiller can realize a series of adjustment functions such as temperature adjustment and temperature difference adjustment.
