What is a CO2 Laser? How to Select a CO2 Laser Chiller?

   What is a CO2 Laser?

CO2 lasers are a type of molecular gas laser that emits in the long-wavelength infrared spectrum. They rely on a gas mixture as the gain medium, which includes gases like CO2, He, and N2. A CO2 laser comprises a discharge tube pump source and various optical components. In a CO2 laser, the gaseous gain medium CO2 fills the discharge tube and is pumped electrically through DC, AC, or radiofrequency methods to create particle inversion, generating laser light. 

What are the Applications of CO2 laser?

CO2 lasers can emit infrared light with wavelengths ranging from 9μm to 11μm, with a typical emission wavelength of 10.6μm. These lasers typically have average output powers ranging from tens of watts to several kilowatts, with a power conversion efficiency of approximately 10% to 20%. As a result, they are widely used in laser material processing, including cutting and processing materials such as plastics, wood, mold plates, and glass sheets, as well as cutting, welding, and cladding metals like stainless steel, aluminum, or copper. They are also used for laser marking on various materials and 3D laser printing of polymer materials.

How to Select a CO2 Laser Chiller?

CO2 laser systems are known for their simplicity, low cost, high reliability, and compact design, making them a cornerstone of precision manufacturing. However, the process of pumping energy into a significant volume of CO2 gas generates heat, leading to thermal expansion and contraction in the laser structure, resulting in relative output power instability. Turbulence in the gas-assisted cooling process can also introduce instability. Choosing TEYU S&A laser chillers can ensure stable CO2 laser beam output by providing cooling and temperature control. So how to select the suitable CO2 laser chiller for CO2 laser machines? For instance, an 80W glass CO2 laser tube can be paired with the TEYU S&A chiller CW-3000, while a laser chiller CW-5000 can be selected to cool a 60W RF CO2 laser tube. TEYU water chiller CW-5200 can offer highly reliable cooling for up to 130W DC CO2 laser while the CW-6000 is for 300W CO2 DC laser tube.

How Does a CO2 Laser Marking Machine Work? What's Its Cooling System?

Do you know how a CO2 laser marking machine works?

A CO2 laser marking machine operates by utilizing a gas laser with an infrared wavelength of 10.64μm. CO2 gas is injected into a high-pressure discharge tube, causing a glow discharge, which releases laser energy from the gas molecules. After amplifying this laser energy, it forms a laser beam used for material processing. This laser beam vaporizes the surface of non-metallic and organic materials, creating permanent marks. It employs a small point to mark the surface, minimizing the risk of radial fragmentation and cracks, and promoting a more consistent material appearance.

Understanding the Temperature Indicators of Your Industrial Chiller to Enhance the Efficiency!

As a crucial cooling component for laser equipment, it's vital to pay close attention to the operating parameters of an industrial chiller to improve its efficiency and overall performance. Let's delve into some key operational parameters of industrial chillers:

1. Exhaust temperature is one of the critical parameters.

During the summer, the compressor's exhaust temperature tends to be high, requiring careful operation. If the exhaust temperature is too low, it can affect the cooling of the motor windings and accelerate the aging of insulation materials.

2. The temperature of the compressor casing is another parameter that warrants attention.

The heat generated by the electric motor and friction in the refrigeration unit can cause the copper tube casing to emit heat. Temperature differences between the top and bottom can lead to condensation on the upper compressor casing when the environmental conditions are humid at 30°C.

3. Condensation temperature is a vital operational parameter in the refrigeration cycle.

It directly affects the water chiller's cooling efficiency, power consumption, safety, and reliability. In water-cooled condensers, the condensation temperature is generally 3-5°C higher than the cooling water temperature.

4. The room temperature of the factory is another critical parameter requiring special attention.

It is advisable to maintain the room temperature within a consistent range of less than 40°C, as exceeding this threshold can lead to overloading the chiller unit, thereby impacting industrial production. The optimal operating temperature for a chiller falls within the range of 20°C to 30°C.

Specializing in laser chillers for 21 years, TEYU S&A offers over 120 models of industrial water chillers. These water chillers provide reliable cooling support for various laser equipment, including laser cutting machines, laser welding machines, laser marking machines, and laser scanning machines.

The Function And Maintenance Of Industrial Chiller Condenser

Water chiller is a necessary supporting cooling device for the use of industrial processing equipment, whose cooling capacity significantly affects the normal operation of the processing equipment. So, the normal functioning of industrial chiller is a must for the continuous operation of processing devices.

 

The role of condenser

Condenser is an important component of water chiller. During the refrigeration process, the condenser outputs the heat absorbed in the evaporator and converted by the compressor. It is a necessary part of the heat dissipation of refrigerant, whose heat dissipation before refrigerant evaporation is performed by condenser and fan. In this sense, the decrease in condenser performance will directly affect the refrigeration capacity of the industrial chiller.

 

Condenser maintenance

Use an air gun to regularly clean the dust and impurities on the chiller condenser surface, so as to reduce the occurrence of poor heat dissipation caused by the increased temperature of the industrial chiller condenser.

*Note: Keep a safe distance (about 15cm(5.91in)) between the air outlet of the air gun and the cooling fin of the condenser; The air outlet of the air gun should blow to the condenser vertically.
