Air-driven cooling device for high tech electronics.

Our paper presents a cooling device that can produce a stream of cooling air at temperatures down to -50°C. Three different air-driven cooling device prototypes have been developed for cooling of siliconbased charged particle detectors and electronics. The devices are able to provide a range of cooling temperatures at moderate or low heat fluxes to be removed (up to hundreds of watts). Our new AIRCOOLERs use the principle of Vortex tube cooling. A wide range of temperatures down to -50°C is achieved with a nominal standard air pressure of 0.8 to 0.9 MPa which is in the range of the supply lines in the most laboratories and industrial facilities. Their simple box-like design, equipped with Vortex tubes and heat exchangers, has no moving parts and requires only a pressurized dry air supply to provide the cooling effect. It is ideally suited for applications in laboratories and also for applications with a problematic ambient environment, such as strong magnetic fields or high radiation levels.
