What is the refrigeration principle of the fiber laser chiller?

Have you ever wondered how TEYU fiber laser chillers work? Let me introduce you to its amazing cooling system!

Refrigeration Principle Of Water Chiller For Supporting Equipment:

The chiller's refrigeration system cools the water, and the water pump delivers the low-temperature cooling water to the laser equipment that needs to be cooled. As the cooling water takes away the heat, it heats up and returns to the chiller, where it is cooled again and transported back to the fiber laser equipment.

Refrigeration Principle Of The Water Chiller Itself:

In the refrigeration system of a chiller, the refrigerant in the evaporator coil absorbs the heat of the return water and vaporizes it into steam. The compressor continuously extracts the generated steam from the evaporator and compresses it. The compressed high-temperature, high-pressure steam is sent to the condenser and later releases heat (heat extracted by the fan) and condenses into a high-pressure liquid. After being reduced by the throttling device, it enters the evaporator to be vaporized, absorbs the heat of the water, and the whole process circulates constantly. You can set or observe the working status of the water temperature through the temperature controller.

What are the systems that make up a laser welding machine?

Laser welding is achieved by using a high-energy beam to transform into heat energy to radiate onto the workpiece, then instantly melting and bonding the material. The speed of laser welding is fast that it can satisfy the needs of continuous mass production. Its advantages such as smooth and beautiful processing workpiece, polish-free treatment can save time and costs for manufacturers. Laser welding has gradually replaced the traditional welding. So what are the main components of a laser welder?

1. Laser welding host

Laser welding host machine mainly produces laser beam for welding, which is made up of power supply, laser generator, optical path and control system.

2. Laser welding auto workbench or motion system

This system is used to realize the movement of laser beam according to the welding track under specific requirements. To realize the automatic welding function, there are 3 control forms: workpiece moves with laser head fixed; laser head moves with workpiece fixed; both laser head and workpiece move.

3. Work fixture

During the laser welding process, laser welding work fixture is used to fix the welding workpiece, making it can be repeatedly assembled, positioned and disassembled, which benefits the automatic welding of the laser.

4. Viewing system

Generic laser welder should be equipped with a viewing system, which is conducive to the accurate positioning during the welding programming process and the effect inspection when welding.

5. Cooling system

During the operation of the laser machine, a large amount of heat is generated. So water-cooled way is needed to cool down the laser machine and keep it to the proper temperature range, which helps to ensure the laser beam quality and output power, and prolongs the service life of the laser.

S&A laser welding machine chiller comes with dual temperature control system, while the high temperature circuit cools the laser head and the low temperature circuit cools the laser machine. One device serves several purposes, which saves costs and space. The laser chiller is also equipped with multiple warning protections: time-delay and over-current protection of compressor, flow alarm, ultrahigh/ultralow temperature alarm.

Due to the flexible requirement of laser welding, handheld laser welding machine is popular on the market. Correspondingly, Teyu launches all-in-one handheld laser welding machine chiller, which can be flexibly used matching with your handheld laser welder.

The improvement of laser cutting technology and its cooling system

The metal processing industry has been ushering in waves of change in today’s society with rapid technological development. Metal processing is mainly the cutting of metal materials. For the need of production, there is increasing cutting demand for metal materials of different textures, thicknesses and shapes. And the requirements for the workpiece cutting process are higher and higher. Traditional cutting can no longer satisfy the needs and is replaced by laser cutting, which is the main technology in the metal processing industry.

Compared with traditional cutting methods, what advantages does laser cutting technology have?

1. Laser cutting technology features higher cutting precision, faster cutting speed and smooth & burr-free cutting surface. Non-contact processing between the laser head and the workpiece will not cause scratches on the workpiece surface, without the step of secondary grinding. The high-precision processed product can improve the material utilization rate and save production costs.

2. Cost-saving and efficient. Professional computer-controlled cutting software supports cutting into any complex graphics and words, which greatly saves labor and time costs for enterprises to realize highly automatic processing, ensure good cutting quality and improve production efficiency.

3. Wide application. Laser cutting machine, with unmatchable production advantages compared with other traditional cutting processes, is not only applicable to precise component processing but also large metal plate pipe processing.

Although laser metal cutting has huge advantages over traditional cutting methods, along with the higher requirements, it still has several major pain points: (1) Higher power laser cutting devices are chosen to satisfy the processing thickness needs; (2) Batch processing of high-reflectivity materials often leads to laser damage; (3) The processing efficiency of non-ferrous materials is low.

The appearance of the laser scanning cutting machine: The laser scanning machine newly developed by Bodor Laser adopts a self-developed optical system device, optical path space programming technology and patent process algorithm to achieve: (1) At the same power, the ultimate cutting thickness has been greatly increased; (2) At the same power and thickness, the cutting speed has been significantly improved. (3) Fearless of high reflectivity, it solved the problem that high-reflectivity materials can not be processed in scores.

Whether it is the laser cutting machine or laser scanning cutting machine, its cutting principle is to rely on the laser beam irradiation on the surface of the workpiece, so that it can reach the melting or boiling point. Meanwhile, beam-coaxial high pressure gas blows away molten or vaporized metals, during which immense heat is generated thus will affect the workpiece, reducing the quality of processing products. S&A laser chiller can provide laser cutting/laser scanning cutting machines with a reliable cooling solution featuring a constant temperature, constant current and constant voltage. S&A chiller, which can precisely control the temperature and stabilize the beam output to ensure the continuous and stable operation of laser cutting machines, is a good helper in cooling your laser equipment!

What should be paid attention to when using an industrial water chiller?

Only by using the chiller in an appropriate environment can it play a greater role to reduce processing costs, improve efficiency, and prolong the laser equipment service life. What should be paid attention to when using industrial water chillers?

1. The operating environment

Recommended environment temperature：0～45℃, environment humidity：≤80%RH.

2. Water quality requirements

Use purified water, distilled water, ionized water, high-purity water and other softened water. But oily liquids, liquids containing solid particles, and liquids corrosive to metals are prohibited.

Recommended antifreeze ratio: ≤30% glycol (added to prevent water freezing in winter).

3. Supply voltage and power frequency

Match the power frequency of the chiller according to the usage situation and ensure that the frequency fluctuation is less than ±1Hz.

Less than ±10% of power supply fluctuation is allowed (short-time operation does not affect the use of the machine). Keep away from electromagnetic interference sources. Use the voltage regulator and variable-frequency power source when necessary. For long time operation, the power supply is recommended to be stable within ±10V.

4. Refrigerant usage

Utilizing Laser Marking Technology in COVID-19 Antigen Test Cards

The raw materials of COVID-19 antigen test cards are polymer materials such as PVC, PP, ABS, and HIPS, which come with the following characteristics:

(1) Favorable physical and mechanical properties, as well as chemical stability. 

(2)Readily available and inexpensive, ideal for the production of disposable medical supplies.

(3)Ease of processing and low manufacturing cost, great for various molding methods, facilitating the processing into intricate shapes and new product development.

UV laser marking is to use an ultraviolet laser to directly destroy the chemical bonds connecting the atomic components of the substance. This kind of destruction is called the "cold" process, which does not produce heating to the periphery but directly separates the substance into atoms. In the production of POCT detection reagent cards, laser processing can make full use of high energy to promote the carbonization of the surface of the plastic itself or decompose certain components on the surface to form a green body to make the plastic foam, so that color difference between the laser acting part of the plastic and the non-acting area can be formed to form the logo. Compared with ink printing, UV laser marking features a better effect and higher production efficiency.

UV laser marking machine is capable of marking various types of text, symbols, and patterns on the surface of antigen detection boxes and cards. The use of laser processing is highly efficient and convenient, making it an ideal choice for the fine processing of plastic products. It can mark a range of information including text, logos, patterns, product and serial numbers, production dates, barcodes, and QR codes. The "cold laser" processing is precise and the industrial personal computer has strong anti-interference capabilities, ensuring long-term stable operation and long service life. Additionally, it can operate continuously for 24 hours.

TEYU Industrial Chiller boosts the stable marking of the UV laser marking machine

No matter how good the equipment is, it needs to operate at a specified temperature, especially the laser. Excessively high temperatures can lead to unstable laser light output, impacting marking clarity and equipment efficiency. TEYU UV laser marking chiller helps the marking machine to stably mark COVID-19 antigen test cards. Under TEYU CWUP-20 chiller’s precise temperature control, ultraviolet laser markers can maintain a high beam quality and stable output, optimizing marking accuracy. Additionally, the chiller has passed rigorous international quality standards, including CE, ISO, REACH, and RoHS certifications, making it a reliable and efficient tool for cooling UV laser marking machines!

How to judge the quality of industrial water chillers？

Industrial water chillers have been widely applicable to a broad range of fields, including the laser industry, chemical industry, mechanical processing manufacturing industry, electronic industry, automobile manufacturing industry, textile printing, and dyeing industry, etc. It's no exaggeration that the quality of the water chiller unit will directly affect the productivity, yield, and equipment service life of these industries. From what aspects can we judge the quality of industrial chillers?

1. Can chiller cool quickly?

A good-quality industrial chiller can cool down to the temperature set by the user in the shortest time because the range of space temperature needs to be lowered is different. If it needs to consume more energy in a unit of time to decrease the temperature, it means the cost of using the industrial water chiller is significantly high, which will lead to a continuous increase in enterprise expenses. This point can determine whether the water chiller can reduce production costs for the enterprise.

2. Can chiller control the temperature precisely?

Industrial chillers can be divided into heat dissipating type (passive cooling) and refrigerating type (active cooling). The ordinary passive cooling industrial chiller is not demanding in temperature precision, expected to dissipate the heat for the industrial device generally. 

Refrigerating type of industrial chiller allows their users to set the water temperature. It is highly sensitive to the machine temperature in the laser industry, so the temperature precision of the laser chiller is extremely important to the laser source.

3. Can chiller alert timely?

Whether there are multiple alarm functions, and whether these alarms ring timely in case of emergency are all-important to both the processing equipment and laser chiller.

Generally, industrial chillers need to run for a long period. A long working time will also cause workpiece wear and failure. So, prompt alarm warnings can remind users to handle the problem quickly and protect equipment safety and production stability.

4. Are component parts good?

An industrial chiller consists of compressor, evaporator, condenser, expansion valve, water pump, etc. The compressor is the heart; Evaporator and condenser play the role of heat absorption and heat release respectively. The expansion valve is the flow regulating valve in the refrigeration system as well as the throttling valve in the refrigeration equipment.

The above-mentioned parts are the core components of laser chiller. The quality of components also determines the chiller quality.

5. Are the manufacturer qualified? Are they operating in accordance with the norms?

Qualified industrial chiller manufacturer boasts scientific test standards, so their chiller quality is relatively stable.
