How do laser equipment deal with the condensation crisis?

Humid air is the "invisible killer" of laser equipment, especially in spring, plum rain season, return of south wind, or high humidity workshop. Once condensation occurs on the surface of the equipment, the equipment may be shut down at the least and core components may be burned at the worst. Don't worry, the S&A chiller can help you easily deal with the condensation crisis

Condensation

When the surface temperature of the laser drops suddenly due to traditional heat dissipation methods, the ambient humidity exceeds 60% and the body temperature is lower than the dew point temperature, the water vapor in the air will instantly condense into water droplets on the surface of the device, just like condensation water forms on the outer wall of an iced soda bottle. This is the "condensation" phenomenon.



The harm of condensation to laser equipment

Optical lenses fog up, light beams scatter and processing accuracy decreases

 

Circuit boards become damp and short-circuit, causing equipment downtime and even fires

 

Metal parts are prone to rust, and maintenance costs soar!

The “three major pain points” of traditional humidity control solutions

Air conditioning dehumidification: high energy consumption and incomplete coverage;

 

Desiccant adsorption: requires frequent replacement and is difficult to cope with continuous high humidity;

 

Equipment shutdown insulation: Although it can alleviate condensation, it affects production efficiency and only treats the symptoms, not the root cause.

Reasonable setting of chiller water temperature

Considering the temperature and humidity of the actual working environment, set the water temperature to a temperature higher than the dew point of the current environment (the dew point temperature varies with the ambient temperature and humidity, see the table below for details) to effectively avoid condensation caused by excessive temperature differences.


Emergency treatment after condensation

Immediately shut down the device and cut off the power supply. Wipe the condensed water on the outside of the device with a dry cloth.

 

Reduce humidity by using an exhaust fan or dehumidification equipment.

 

Preheat the device. After the humidity is reduced, preheat it for 30-40 minutes before turning it on to avoid condensation again.

 

Spring is humid, so please pay attention to moisture-proof maintenance of laser equipment to ensure stable operation of equipment and smooth production

Carbon fiber fuselage with 8m seams can be CO2 laser welded

Image
European researchers  say they have successfully welded two halves of an 8-meter-long fuselage made of carbon-reinforced fibers with a CO2 laser. This means that ultralight passenger aircraft can be manufactured using this method.   The demonstration, completed by a large international consortium led by Airbus and comprising several Fraunhofer institutes, provides proof of concept for the chipless connection of carbon fiber-reinforced thermoplastic (CFRTP) component structures with a CO2 laser. Dynamic Beam Shaping Working under the Multifunctional Fuselage Demonstrator (MFFD) project, which is part of the EU's wider Clean Skies 2 research program, the team at the Fraunhofer Institute for Materials and Beam Technology (IWS) in Dresden says the novel construction method and process will significantly reduce weight, material and time. The novel construction method and process will significantly reduce weight, material, and time.   They used a CO2 source to weld long seams ...
