Laser Chiller: Your Complete Buying Guide

Laser marking is the most popular industrial processing method in the late twentieth century.

Domestic laser drilling machine, laser engraving machine, laser welding machine, laser printer, laser cutting machine, and other laser processing equipment research and development, production, processing enterprises continue to emerge.

What is Laser Chiller?

The laser chiller is an individual application of the industrial chiller to the laser industry.

A laser chiller mainly performs water circulation cooling on the laser generator of the laser equipment and controls the use temperature of the laser generator so that the laser generator can be kept for a long time. normal work.

During the long-term operation of the laser equipment, the laser generator will continuously generate high temperatures. If the temperature is too high, it will affect the normal operation of the laser generator.

Therefore, a laser chiller is required to perform water circulation cooling and temperature control.

For the type of laser generator, the chiller classification method, the laser chiller can be divided into carbon dioxide glass laser tube laser chiller, carbon dioxide metal RF tube laser chiller, semiconductor side pump laser chiller, semiconductor end pump laser chiller, YAG laser Chiller, fiber laser chiller, UV laser chiller.

How to size a suitable laser chiller for your laser machine?

Before we know these answers, let’s have a look at how is the laser machine working?

Laser chiller not only protects CO2 laser tube, YAG solid-state laser crystal, and lamp riot during laser processing.

A full and constant laser cavity temperature is guaranteed by laser output power stability, laser cavity without thermal deformation, laser beam quality and so on.

Choosing the right laser chiller can greatly improve the life and processing accuracy of the laser, and maximize the performance of the laser equipment.

However, most laser chiller users and manufacturers in the selection and recommendation of laser chiller are often very vague concept, many laser chillers on the market are also unclear indicators, the user equipment is also a large flow, cannot accurately make reasonable use of the laser equipment used protection.

The following indicators are key to the selection of laser chillers:

Cooling capacity

a. As the name suggests, the actual cooling capacity of the laser chiller is the first indicator of cooling capacity selection.

b. Generally, we can calculate the calorific value of the laser according to the photoelectric conversion efficiency of the laser, and then choose.
P heat = P laser / μ
Assuming that the thermal efficiency μ of the glass tube CO2 laser is generally 15%, the 80W laser requires a minimum of 80/0.15 = 533W.
That is to say: while generating an 80W laser, the laser injects 533W of energy, and the ineffective energy needs to be taken away by the water cooler.

c. Sometimes we directly determine the cooling capacity of the laser chiller based on the input power of the laser power minus the output power of the laser.

For example, our commonly used RF lasers and solid-state lasers will indicate the power supply voltage and current of the rated full power.

Taking the coherent 70W RF laser as an example, it requires a power input of 48V25A, instantaneous 36A, and can calculate the input power up to 1200W.

I hope the above information is helpful for your selecting the right laser chiller.

2. Water flow and booster pump head
Everyone will pay attention to the amount of cooling, and will often ignore the indicator of water flow.

The cooling capacity of the laser chiller represents the cooling capacity provided by the compressor, and the water flow represents the ability of the chiller to take away heat.

This causes the phenomenon that people often see: a chiller with a nominal cooling capacity of 1000W is connected to an 80W glass tube, a chiller.

At 25 ° C, the laser tube is hot and hot; in fact, it does not play a role.

3. Thermal efficiency and water volume
The above concept leads to the concept of water cooling machine thermal efficiency and water volume, which is the working control mode of the compressor and the size of the water tank.

Generally, the larger the tank, the better, but the different compressor control methods in design will be very different.

This is the same compressor cooling capacity and water volume. The operation control mode with the PID feedback function will greatly improve the cooling capacity of the overall laser chiller system.

4. Temperature control accuracy
This index is completely from the requirements of the laser. For semiconductor lasers, the temperature control accuracy must be ±0.1 °C, which requires the compressor to predict the temperature change law, the adaptive load change, and generally, the water cooler with integrated temperature control module is impossible to do.

To this point. Of course, for CO2 lasers, the temperature requirement is ±2°C to ±5°C, and most of the dedicated water coolers on the market can do this.

5. Water quality requirements and water filtration and water circulation system materials

. This comprehensive indicator is often ignored, but it is very reusable and directly affects the life of the laser.
i. For the CO2 glass tube laser, the lens at both ends belongs to the water flow dead angle, and it is easy to retain impurities in the water, resulting in poor heat dissipation.

The micro-deformation of the lens directly affects the output beam quality and spot pattern of the laser.
Ii. For the RF laser, the accumulation of scale and copper rust on the heat sink will cause the temperature of the cavity to be too high, and the temperature sensor will alarm, and the laser will not emit light.
Iii. For YAG lasers, the surface cleanliness of the pump lamp, crystal, and gold-plated cavity directly affects the optical power and spot pattern; the tiny water hole blockage in the semiconductor module directly burns the bar.

b. Most of the laser chiller refrigerant tubes on the market use copper tubes and the evaporation trays are directly placed in the cooling water, which will generate a large amount of copper rust, which directly affects the laser.

c. Many filter-free ones are the direct addition of tap water to the laser chiller or the use of pure water that is not replaced for a long time.

It will cause the growth of bacteria and impurities to deposit on the laser, affecting the life and use of the laser.

Installation Instruction of Your Laser Chiller

The installation of the laser chiller is very simple.

The first step of the new machine can be carried out as follows:

1. Open the package and check if your laser chiller is in good condition and the accessories are ready.

2. Unscrew the water injection port of your laser chiller and add cooling water. When adding water, you should observe the water level of the water level gauge and add water slowly.

Be careful not to let the water overflow! For the cooling of carbon steel equipment, an appropriate amount of anti-corrosion agent should be added. Non-corrosive antifreeze should be added to cold areas in the north.

3. Connect the outlet pipe and the inlet pipe from the laser chiller according to the laser machine or equipment.

4. Plugin the power cord and turn on the power switch. (No water start!)
(1) After the power switch is turned on, the laser chiller circulation pump starts working. When the new laser chiller is turned on for the first time, there will be more air bubbles in the pipeline, which will cause the machine to occasionally report the flow. This new laser chiller will return to normal after a few minutes of operation.
(2) After the first start-up, your laser chiller is necessary to check the water pipe for leaks immediately.
(3) After the power is turned on, if the water temperature is lower than the set temperature, it is normal for the fan of the machine not to work. The thermostat automatically controls the operating status of the compressor, solenoid valve, fan, etc. according to the set control parameters.
(4) Since the compressor and other devices have a long starting process, they vary from tens of seconds to several minutes depending on different working conditions, so do not switch the machine frequently.

5. Check the water level of the water tank in your laser chiller
After the new laser chiller is turned on, the air in the water pipe is drained, and the water level of the water tank will drop slightly.

In order to keep the water level in the green area, water can be added again. Observe and record the current water level.

Wait until the laser chiller runs for a period of time and observe the water level gauge again. If the water level drops significantly, check the leak of the water pipe.

6. Adjust the parameters of the laser chiller temperature controller

Laser chiller daily maintenance and common problem solutions

Laser chiller as an important part of the YAG laser welding system is directly related to the normal working state of the laser welding machine, and the daily chiller frequency of the laser welding machine is quite high.

So we should pay more attention in normal times. Maintain and learn to troubleshoot when your laser chiller fails.

1.check the compressor of your laser chiller regularly:

The compressor is equivalent to the heart of the laser chiller. Its quality directly affects the stability of the chiller.

If the compressor has damage, the maintenance cost is relatively high, so the compressor has abnormal sound or other in daily use. The situation should be contacted immediately by the supplier to find out the cause and resolve it.

2.regularly clean the laser chiller condenser and evaporator:

The condenser/evaporator is the second-largest component of the laser chiller. It is best to clean it once every six months.

Generally, the laser chiller uses a finned condenser, which will absorb dust during operation, and it is best to clean it regularly.

3.regular replacement of circulating cooling water:

The purity of the cooling water is the key to ensure the output efficiency of the laser welding machine and the life of the laser concentrating cavity assembly.

The conductivity of the internal circulating water should be checked once a week to ensure that its conductivity is 30.5 MW·cm, which must be replaced once a month.

For circulating deionized water, the conductivity of the newly injected pure water must be 32 MW·cm. Always observe the color change of the ion exchange column in the cooling system.

If the color of the resin in the exchange column is found to be dark brown or even black, replace the resin immediately.

4. regularly remove and wash the laser chiller dust grid:

After the laser chiller is used for a period of time, the dustproof grid will absorb some dust.

When there is too much dust, it will affect the heat dissipation of the chassis.

Regularly removing and disassembling the dustproof grid will help ensure the refrigeration stability of the chiller.

5. Replacing the circulating cooling water is an important part of the maintenance of the laser chiller.

Since the circulating cooling water is in operation, it will take away certain impurities such as dust and metal scraps along with the circulating process.

If the circulating cooling water is not regularly replaced. This will cause the laser chiller pipe to clog, so it is necessary to change the circulating cooling water frequently.

In addition, you should also pay attention to regularly remove and clean the dust net and clean the dust on the laser chiller condenser, and do a good job of maintenance to ensure better operation of the equipment.

The cooling water is usually changed once every three months. If necessary, the anti-scaling agent used will be arranged to prevent the scale from forming a blocked water path.

In order to ensure that the laser chiller does not affect the safety of your laser machine in the abnormal situation of the cooling water circulation, normally the laser chiller has a low flow alarm protection function.
