How powerful a fiber laser is that a chiller needs to be water cooled

The optical termination of the laser head is connected to a QBH compatible fiber module (PS: should be the main body of the fiber) and a 100 m QBH fiber output (PS: the connector mentioned by the customer should be the QBH connector used to cooperate with the fiber laser collimation system), the QBH connector outputs divergent light, which should have heat, so the fiber needs two independent water cooling.

Usually 500W fiber laser cooling, we recommend double pump double temperature double control chiller CW-6100AT; And the 750w-1000w fiber laser cooling.

You can put your fiber laser parameters and Han's Refrigeration said, they will tell you the most professional answer, you can learn more about Han's Refrigeration.

The power of the fiber laser needs to be cooled by the chiller, which needs to be considered in combination with the parameters of the fiber laser, and then the fiber laser chiller with the appropriate parameters is selected.

How does the fiber laser match the chiller, according to the chiller model produced by each chiller company, the corresponding matching laser. Take fiber lasers as an example, the chillers commonly used with fiber lasers on the market adopt a dual-temperature design, and the double-filter protection is referred to as "dual-temperature dual-control chiller". Let's say:

The DIC010ADH-LC2 is suitable for fiber lasers up to 500W, the DIC012ADH-LC2 is suitable for fiber lasers up to 700W, and the DIC030ADH-LD2 is suitable for fiber lasers up to 2000W. It is specially used for the corresponding fiber laser.

Femtosecond fiber lasers can be widely used in various fields, and after using femtosecond fiber lasers for a long time, the laser power gradually decays, which has many human factors and the factors of the machine itself.

1. Human factors. Femtosecond fiber lasers are mainly used for external optical path generator maintenance. After a long period of work, the downward power is inevitable, when the power drop affects the operation effect, it needs the maintenance of the optical path, and when the repair is completed, the working capacity will be restored.

2. Laser factor. Lasers are alive, and different quality lasers have different service life, so users should be clear about their service life when purchasing lasers, so as to facilitate maintenance work.

3. Environmental factors. In addition, lasers have high requirements for the air quality of the environment in which they are used. Try to use the laser in an environment with high ambient air quality.

Therefore, the femtosecond fiber laser can be matched with a suitable chiller to better ensure the light yield of the chiller, delay the power attenuation period of the laser, and prolong its life.

Daily maintenance and maintenance is the secret of the chiller's normal operation, which can not only prolong the service life of the chiller, but also help to improve the work efficiency of the equipment and chiller, and ensure the refrigeration stability of the special S&A cold water or old finger machine. The above are the reasons for the attenuation of femtosecond laser power shirt matching rate. When users of the S&A chiller encounter problems with the chiller, the S&A will serve you as soon as possible.

For more professional operation and guidance, you can directly contact the after-sales service center of the S&A chiller manufacturer for detailed consultation. The S&A chiller has a perfect pre-sale, in-sale and after-sales service system, so that users can consult and use it with peace of mind.

The general matching rule is that the cooling capacity of the chiller is greater than the heat generation of the laser equipment.

However, because there are many types of lasers, such as solid-state lasers, gas lasers, etc., the rules of different laser types are different, and it is also necessary to combine the cooling capacity, temperature control accuracy, pump flow head and other technical parameters of each laser chiller.

1. Refrigeration capacity

That is, the refrigeration capacity of the chiller. According to the photoelectric conversion efficiency of the laser equipment, the heat generated by it is calculated, and then the appropriate chiller is selected. Different types of chillers will also be different in this aspect, if you don't know much about this aspect, welcome to consult the professionals of the Cool Era.

2. Temperature control accuracy

This indicator comes entirely from the requirements of the laser, and the temperature control accuracy must be for the semiconductor laser, which requires the compressor to predict the temperature change law and adapt to the change of load, which is generally impossible to do with the water cooler with the integrated temperature control module. Of course, for CO2 lasers, the temperature requirement is 2 to 5, which can be achieved by most special water coolers on the market. However, the Kuling era is one of the few laser chillers that has really reached it.

3. Water flow rate and booster pump head

The refrigeration capacity represents the refrigeration capacity provided by the compressor, and the water flow represents the ability of the chiller to take away the heat, which causes the phenomenon that we often see: the chiller with a nominal cooling capacity of 1000W is connected to an 80W glass tube, the chiller shows 25, but the laser tube is hot; In fact, it did not play a role in the application.

Of course, in addition to the above three aspects, we should also consider the thermal efficiency and water volume, water quality requirements, and the material ...... of water filtration and water circulation systemsetc.

Glad Caedley chiller for you.

The laser chiller is mainly to cool the laser generator of the laser equipment with water circulation, and control the temperature of the laser generator, so that the laser generator can keep working normally for a long time. The following 258 platform will introduce the selection method of laser chiller.

The following are the important indicators for the selection of laser chillers:

1. The refrigeration capacity of the laser chiller:

As the name suggests, the working principle of the laser chiller is to send the frozen water in the water tank of the chiller to the laser machine that needs to be cooled, and then the heat of the laser is brought forward and then returned to the water tank and then cleared through the cooling cycle of the chiller to achieve the effect of cooling, assuming that the thermal efficiency of the glass tube CO2 laser is generally 15%, and the minimum need for the 80W laser: 80

2. Pump pressure of laser chiller (Yang Cheng size).

The refrigeration capacity of the chiller represents the refrigeration capacity of the compressor, and the water flow represents the ability of the chiller to take away the heat, and the speed of the water flow is due to the relationship between the pressure of the laser chiller water pump Yang Cheng, if the water pump Yang Cheng is too low (some "cheap" laser chiller water pump Yang Cheng on the market is not even 10 meters), then the speed of water flow is very slow, and the cooled water in the water tank cannot be circulated to the laser in time, so The heat of the laser equipment can not be cooled away in time, so this causes a phenomenon that we often see: the nominal cooling capacity of 1600W laser chiller is connected to a 75W semiconductor laser marking machine, the chiller shows 25, and the laser machine is hot, which is the laser chiller does not play a cooling role.

3. Water filter of laser chiller.

1. According to our experience, matching 700W-800W fiber laser, S&A CW-6200AT dual-temperature double-pump chiller can be used, with cooling capacity and temperature control accuracy; The 1000W fiber laser can use CW-6300ET dual-temperature double-pump chiller, which has a cooling capacity of dual-channel circulating cooling system, which can cool the fiber laser body and cutting head at the same time, and is equipped with ion adsorption filtration and detection functions to purify and cool the water quality and meet the requirements of fiber lasers.

Second, the selection of laser chiller manufacturer brand, you can start from the following aspects:

1. Look at the production scale, production capacity, and quality management of the chiller manufacturer 2. See whether the chiller manufacturer has various qualification certifications, such as ISO quality certification, CE certification, etc. 3. When choosing a chiller, you must choose a certain reputation and customer reputation 4. It is necessary to consider whether the quality of the chiller is stable and how the failure rate is 5. Whether the cooling capacity of the selected chiller can meet the cooling requirements of the equipment and whether it is suitable for cooling its own equipment.

6. What is the service life of the chiller and how long is the warranty period?

7. Whether the chiller manufacturer does a good job in the after-sales of the chiller, so that it can be dealt with quickly, and how is the service attitude.

1. Selection method of laser chiller: according to the photoelectric conversion efficiency of the laser, the calculation formula of laser calorific value is: p heat = p laser · (1-n) n

P-heat: The heat generated by the laser (W).

pLaser: Laser input power (W).

n: Laser photoelectric conversion rate (%) is determined according to different lasers.

The value range of carbon dioxide laser is 8%-10%.

The value range of lamp pump laser is 2%-3%.

The value range of diode-pumped lasers is 20%-30%.

The value range of optical brazing laser: 20%-30%.

For example, the output power of a certain brand of carbon dioxide 2000w laser is 2000w, and the photoelectric conversion rate is .

p heat = 2000 * (

The refrigeration capacity of the laser chiller should be greater than the calorific value, and you can refer to the Tianfeng TF-LS-23KW laser chiller.

2. Schematic diagram of laser chiller connection.

The temperature of the chiller required for the fiber laser is set in the range of 20-30 degrees

In the case of load, the manufacturer of Kuling Times suggests that you can control the temperature range of the laser chiller in summer between 20-30 degrees.

Laser chiller temperature potato mambi setting method:

The display screen of the laser chiller adopts capacitive touch buttons, and the main functions include power on and off operation and setting the water temperature in the water tank. The buzzer will make a short "drop" sound when the key touch is active, and it will not react when the touch is invalid.

1. Press and hold the "ON off" button for 2 seconds to complete a power switch.

2. Press and hold the "set" button for 2 seconds to enter the setting interface, at this time, the temperature awareness vertical area on the display screen will display "set f0", and then each time you click the "set" button, the area will display "set f0", "set f1", "set f2" three logos in a loop. "set f0" indicates that the target temperature can be set at this time; "set f1" indicates that the high temperature alarm value can be set at this time; "set f2" indicates that the low temperature alarm value can be set at this time. In any of the settings interfaces in "Set F0", "Set F1", and "Set F2", press and hold for 2 seconds to restore the display to its normal display state.

If you stay on the settings screen for more than 10 seconds without any button operation, the display will also return to its normal display state.

3. The "up" button is valid when setting the interface. When in the "set f0" interface, click this button to increase the set temperature, press and hold for more than 2 seconds, the set temperature will increase continuously, the maximum value is 35; When you are in the "SET F1" interface, click this button, the high temperature alarm temperature difference value increases, press and hold for more than 2 seconds, the high temperature alarm temperature difference value increases continuously, and the maximum number value is 10. When you are in the "SET F2" interface, click this button, the low temperature alarm temperature difference value increases, press and hold for more than 2 seconds, the low temperature alarm temperature difference value increases continuously, and the maximum value is 10.

4. The "down" button is valid when setting the interface. In the "set f0" interface, click this button to set the temperature to decrease, press and hold for more than 2 seconds, the set temperature will decrease continuously, the minimum value is 10; When you are in the "Set F1" interface, click this button, the high temperature alarm temperature value decreases, press and hold for more than 2 seconds, the high temperature alarm temperature difference value decreases continuously, and the minimum value is 0. When you are in the "Set F2" interface, click this button, the low temperature alarm temperature difference value decreases, press and hold for more than 2 seconds, the low temperature alarm temperature value decreases continuously, and the minimum value is 0.

Whether the optical fiber excitation machine needs to be equipped with a dual-temperature and dual-control chiller is mainly determined by the power of the fiber laser.

Like the current market 500w fiber laser machine cooling, it is generally necessary to use a dual-temperature and dual-control cooling and water servant. Because the fiber laser machine has a laser body and lenses that need to be cooled, at this time, the dual-temperature and dual-control chiller we chose in the Kuling era can cool the laser body and lenses at the same time.

Because of the CS-RMC-10U series fiber laser chiller of the Kuling era.

There are two independent water cooling systems, which cool the main body and lenses respectively, one is multi-purpose, which helps customers save costs and is convenient for customers, and users no longer worry about taking up space and difficult to handle. As it can be seen, the fiber laser equipped with a dual-temperature and dual-control chiller will bring great convenience to customers.
