What is water cooled laser technology and laser chiller selection?

At present, the chiller is generally used as the cooling system of the laser on the market, mainly because the cost of the chiller is low, and the refrigeration effect is stable and easy to operate. Because the laser will generate a certain amount of heat during operation, if the water is not carried out through the chiller in time, it will lead to thermal deformation of the laser cavity during long-term operation, affecting the quality of light, cutting accuracy and its service life. For different lasers, chillers of different configurations can be matched, such as fiber lasers, which can be cooled and cooled by dual-temperature and double-pump chillers.

Laser water cooler is like a lubricant for laser equipment, and it is an indispensable partner for laser equipment such as laser marking machine, laser cutting machine, laser welding machine, etc.! The laser water cooler not only takes away the heat generated when the laser works with high efficiency, cools the laser, but also improves the working precision and output of the laser. Features:

1. The refrigeration system components are all international brand components, and the pure stainless steel water tank without coil has a long-lasting and stable refrigeration effect, and the temperature control accuracy is 1; 2. With ultra-high and low temperature display and signal output protection, configure normally open and normally closed output for selection; 3. The chilled water circulation system is connected by stainless steel multistage pump and stainless steel and PVC material, so there is no worry about rust, and pure water or deionized water can be used directly; 4. In the laser (laser) system, the laser generator source, beam controller and electric control cabinet may need additional cooling.

Hello dear, there are several main differences between laser chillers and ordinary chillers:1How it works:

The laser chiller is a cooling system specially designed for laser equipment, and its working principle is to transfer the heat generated by the laser into the cooling medium through circulating water to maintain the stable working temperature of the laser. The ordinary chiller is a general cooling equipment, which is used to cool the heat source in various equipment or process benches. 2.

Temperature control: Laser chillers often need to provide very precise temperature control to ensure that the laser operates within a specific temperature range. A regular chiller may only need to provide a certain range of temperature control.

3.Cooling capacity: Laser chillers typically need to have a high cooling capacity to cope with the large amount of heat generated by the laser.

Ordinary chillers may be comparatively low in terms of cooling capacity. 4.Control system:

Laser chillers usually have more complex control systems, which can achieve precise control and monitoring of parameters such as temperature, flow, and pressure. The control system of the ordinary cold water Zaozhou bridge machine is relatively simple.

Hello dear and happy to answer for you. The difference between laser chiller and ordinary chiller is mainly in the following aspects:1

The range of applications is different: laser chillers are mainly used in laser processing fields such as laser cutting, laser marking, and laser welding, while ordinary chillers are mainly used in general fields such as refrigeration, cooling, and cooling. 2.

Different refrigeration methods: laser chillers use compressor refrigeration and copper tube heat exchange, while ordinary chillers use compressor refrigeration and water pump circulation. 3.

The temperature control accuracy is different: the laser chiller needs to accurately control the temperature, and the temperature control accuracy is generally about 1, while the temperature control accuracy of the ordinary chiller is generally about 1. 4.

Different quality requirements for cooling water contact culture: laser chillers have high requirements for cooling water quality and need to use pure water or deionized water, while ordinary chillers can use tap water or industrial water. 5.

Equipment**different: Because laser chillers need to meet precise temperature control and high-quality cooling water requirements, equipment** is generally higher than ordinary chillers. In general, the main difference between laser chiller and ordinary chiller lies in the scope of application, refrigeration mode, temperature control accuracy, cooling water quality requirements, family noise change and equipment, etc., and the use of trillion judgment households should be selected according to their actual needs and economic conditions when purchasing.

In the laser industry, the importance of laser chillers for laser equipment is self-evident. This is because choosing the right laser cooling system can greatly improve the service life and processing accuracy of the laser, and maximize the performance of the laser machine. Otherwise, if you choose a bad laser chiller, it is likely that you will not be able to accurately protect the laser equipment used, which will directly affect the life of the laser.

Methods for selecting chillers for laser equipment:

1. Refrigeration capacity

That is, the refrigeration capacity of the laser chiller. According to the photoelectric conversion efficiency of the laser equipment, the heat generated by it is calculated, and then the appropriate laser chiller is selected. Different types of laser chillers will also be different in this aspect, users can choose reasonably through some different calculation methods, if users are not very familiar with this aspect, they are also welcome to consult the professionals of the Kuling era.

2. Temperature control accuracy

This index comes completely 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 and guess the 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 currently one of the few laser chillers that has achieved true regret and correction.

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.

4. Thermal efficiency and water volume

In general, the bigger the tank, the better, but the design of different compressors will be very different. This is the same compressor cooling capacity and water volume, and the operation control with PID feedback function will greatly improve the cooling capacity of the overall system.

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

This composite metric is often overlooked, but it is very reused and has a direct impact on the lifetime of the laser. Like many unfiltered chillers, direct tap water or the use of pure water that has not been replaced for a long time will cause the breeding bacteria and impurities to be deposited on the laser, affecting the life and use effect of the laser.

It can be seen that the correct selection method of laser chiller can greatly improve the service life and processing accuracy of the laser equipment, and give full play to the performance of the laser equipment.

The application of industrial chillers covers many industries such as laser cutting, laser welding, engraving, UV printing, laboratory and medical. The chiller manufacturers on the market are also uneven, how should we screen the chiller manufacturers?

First, look at the scale of production.

With its own production line, large-scale production manufacturers, its products are used in various industries, withstand the test of practical applications in various industries, and its product quality is also guaranteed, so there will be such a large sales volume;

Second, look at the research and development capabilities.

A manufacturer should have its own core technology and R&D team. The market continues to push through the old and dig out the source of innovation, the chiller will also have product changes, with the technical team to keep pace with the times, research and development of the chiller suitable for market demand;

3. Product testing.

It is very important that the product is delivered to the customer after the comprehensive inspection is completed, which guarantees the quality of the product and avoids the delivery of unqualified and defective products to the customer;

Fourth, the product is complete.

The product model is complete, which can meet the refrigeration of many types of industrial equipment, and it is also the embodiment of the high productivity of Leng Jingsan water purifier manufacturers.

5. After-sales service.

The people who use the chiller are not necessarily professionals, and when they encounter a failure, they will generally need the help of the manufacturer. If the after-sales service is not timely, it will affect the use of the chiller and delay production.

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.

Laser chiller is an individualized application of industrial chiller to the laser industry, laser chiller is mainly to cool the laser generator of the laser equipment for water circulation, and accurately control the temperature of the laser generator, so that the laser generator can keep working normally for a long time.

Because the laser processing equipment will continue to produce high temperature during the long-term operation, the temperature will affect the normal operation of the laser generator, and the laser chiller of the Kuling era is often required to carry out water circulation cooling and temperature control.

Therefore, the function of the laser chiller is mainly to cool the laser generator of the laser equipment with water circulation, and accurately control the use temperature of the laser generator, so that the laser generator can maintain normal operation for a long time.

Now there are many manufacturers of laser chillers, such as Cadley, Hitachi, York, etc., and Cadley can. It is the KDL-0005 model.
