The cooling system is one of the important components of the laser welding machine. If the cooling system fails, the equipment will stop working at a small level, and even the crystal rod may explode in severe cases. From this, we can see the importance of the cooling system of the laser welding machine.

At present, the cooling systems of laser welding machines mainly include water cooling and air cooling systems. Among them, water cooling is the most widely used.

The laser chiller is an individualized application of industrial refrigeration machines to the laser industry. It is a cooling water device that can provide constant temperature, constant flow and constant pressure.

The working principle of water cooling of the laser chiller is to first inject a certain amount of water into the water tank in the machine, cool the water through the chiller cooling system, and then use the water pump to send the low-temperature cooling water to the equipment to be cooled. The cooling water in the chiller takes away the heat and then the temperature rises and flows back to the water tank to achieve the cooling effect. Its working principle is:

1. The laser welding machine chiller generally has a filter, which can effectively filter out obvious particulate impurities in the water, keep the laser pump cavity clean and prevent the possibility of water blockage.

2. The chiller uses pure water or deionized water, which is more conducive to the pump light source directly entering the laser material and can produce a better laser mode.

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

4. The chiller uses an imported compressor, the water tank and water pump are made of stainless steel, and the heat transfer coil is also made of stainless steel. This can fully ensure the stability of the chiller and the refrigeration effect. The temperature difference can be within 1°C. The lower the controlled temperature difference, the less the laser is affected by temperature. However, we recommend that the temperature difference be adjusted to about 1°C.

5. The chiller has flow protection. When the water flow is less than the set amount, there is a signal alarm, which can be used to protect the laser and related devices to be cooled.

6. The chiller of the laser welding machine has temperature protection. If the temperature is not suitable, a signal alarm will also appear.

7. The chiller has a series of adjustment functions, such as temperature adjustment and temperature difference adjustment.
