Sometimes LEDs also need water cooling!

Although the LED as Reuters generally considered to be only ambient air cooling equipment, but not always.

Honle UV, based in Germany, manufactures industrial UV LED light sources for UV curing systems for adhesives and coatings, drying, disinfection and other applications.

The company's LED Powerline LC has a wavelength of 365, 385, 395 or 405 nm. Using the 395 nm source as an example, an effective aperture of 25 mW / cm2 is produced over an area of ​​76 x 10 or 114 x 10 mm. Therefore, a large Honle emitter having a light output of about 3 W can be produced, even if the package size of the emitter is only 124 x 20 x 50 mm - meaning that a large amount of heat can be generated in a small volume. In this case, water cooling can bring great benefits.

Honle uses Aspen Systems' compact liquid cooler to cool its UV LED source; specifically, the LED Powerline LC is cooled by the LCS-600 from Aspen Systems, powered by 24 Vdc, using Aspen's steam Compression technology.

Aspen Systems said its chiller was developed under the auspices of the US SBIR program and is designed for use in compact cooling systems in harsh environments. It has been deployed worldwide in the US military and is widely used in medical equipment, laser systems. And scientific instruments, etc.
