Medical lasers often require liquid cooling to maintain a precise laser wavelength and higher output efficiency, to achieve desired beam quality, and/or to reduce thermal stress on the laser system. Pictured on the left is a custom stainless steel tube-fin heat exchanger that Lytron recently designed and manufactured for an OEM for cooling a dental laser. Although the custom stainless steel tube-fin heat exchanger is very similar to Lytron’s 4000 series standard stainless steel tube-fin heat exchanger, it has custom dimensions to meet the OEM’s specific requirements.
Dental lasers require a stainless steel fluid path in the heat exchanger if they are using deionized (DI) water to cool the laser’s diodes. Unlike copper and aluminum, stainless steel is compatible with DI water and other corrosive fluids.
