Liquid Cooling a Laser for System Optimization
smaller gas lasers and many solid-state lasers contain their own built-in cooling system, usually a closed-loop heat exchanger. Larger gas lasers or other high-powered lasers, such as industrial CO2, large-frame argon- and krypton-ion lasers, and excimer lasers, however, typically require an external

High Density Cooling - A Costs & Benefits Review
In previous publications, Rittal Corporation has discussed the design and implementation requirements associated with deploying a high density cooling solution. Today, it can be said with a very high degree of certainty that the IT community is well aware of the critical issues of meeting the power

Keep cool, save money
Hydraulic fan drives cut fuel costs, increase power, and reduce emissions. Edited by Alan L. Hitchcox Retrofitting a Terex 50-ton Payhauler with a variable-speed hydraulic fan drive offers multiple benefits, including a return-oninvestment of only 3 months. Conventional cooling systems drive a fan
