A must-have accessory for a laser marking machine is a cooling system, which can effectively prevent the equipment from heating up and causing damage to the accessories.
During the long-term operation of the laser marking system, if the temperature is too high, it will affect the normal operation of the laser generator. The laser cooler is mainly used to cool the laser and control its temperature so that it can keep running normally.
Usually, there are two types of laser marker cooling systems: water cooling and air cooling.
Different types of laser marking machines are equipped with different laser cooling systems. Fiber laser marker is generally equipped with air cooling, UV with water cooling, and CO2 with water or air cooling, depending on the requirements of the configuration for the cooling system.
Whether the cooling equipment is a laser water cooler or a laser air cooler also depends on the power of the laser engraver itself.
The Difference Between Water Cooling and Air Cooling
The cooling effect of water cooling is better than that of air cooling. Of course, the cost of water cooling is also relatively high. In addition, the water cooler is an independent device, so the device occupies a larger space, and is generally used for high-power laser marking machines.
And air cooling is usually suitable for low-power CO2 laser marking machines, fiber laser marking machines, etc. Air cooling is generally installed directly in the cabinet of laser marking machine, which is small in size and does not take up too much space.
Regular Maintenance of Laser Cooling Equipment
Water coolers require regular maintenance during use.
Change the water in the tank regularly to ensure that the water is pure. Distilled or purified water is recommended.
There should be no debris in the cooling water, and pay attention to whether the water in the return pipe flows smoothly.
Whether it is a water or air cooling system, the tank or fan should be cleaned of dirt and should be cleaned regularly.
Other Precautions of Laser Cooling System
1. If the water tank is not running or there is no water, please do not use and troubleshoot the semiconductor laser marking machine. As semiconductor laser marking belongs to high-temperature thermal processing, it will cause serious consequences without water cooling.
2. If there is any abnormal phenomenon during the operation, please turn off the power in time. After the galvanometer stops working, some inspection and maintenance work should be carried out.
Whether it is a water-cooled or air-cooled laser marking machine, we must use it in accordance with the manufacturer’s operating procedures. The quality of marking and the stability of equipment work are directly related to this.
