Cooling system is an important part of laser welding machine. When purchasing equipment, customers will ask whether the cooling system is air cooled or water cooled. If there is a problem with the cooling system, the equipment will stop running. If the cooling system is damaged, it could explode.

According to the cooling medium, the cooling system can be divided into air cooling and water cooling. If the heat of the high temperature parts of the engine is directly dispersed into the atmosphere, the cooling device is called the air cooling system; The device that transfers this heat first to the cooling water and then into the atmosphere to cool it is called a water-cooling system. Water cooling has the lowest cost, uniform cooling and good effect, so it is widely used.

The chillers of laser welding machines generally have filters, which can effectively filter out the magazines in the water, keep the pump clean and prevent water plugging. It is best to use pure and ionized water in the chiller, and a pressure gauge to observe the water pressure. The chiller generally uses 220V household electricity instead of three-phase electricity, which is more conducive to universal equipment. The chiller of laser welding machine is equipped with temperature protection, if the temperature is too high or too low, there will be a signal warning. The bottom of the chiller has oil flow protection, when the water flow is set, there will be a signal alarm, which can be used to protect the laser and related radiator parts. Water tank, water pump are made of stainless steel, stainless steel can make the chiller more stable, so that the cooling effect is better.
