CO2 Galvo Marking & Cutting



Air or Water Cooled Laser ChillersWhen lasers over a certain power level are utilized in etching/engraving or cutting solutions, heat must be dissipated to keep them from overheating. Water cooling has many advantages over air cooling in efficiency. Technically, water provides superior cooling capacity because it has a thermal conductivity of 0.6062 W/ (m*K) whereas the thermal conductivity of air is only 0.0262. This means heat can be drawn away from laser source more efficiently with water than with air. Water also has a much higher specific heat capacity than air (1.0 J/ (kg*K) versus 0.24), which allows a water cooling system to absorb a lot more energy before heating up.
