The cooling of enclosures and cabinets is a common application in many factories. Often electrical cabinets need to be kept cool in a hot factory to ensure that they continue to operate effectively. Often, if the factory setting is a dirty or wet environment, the deployment of air conditioning units can be problematic. So a viable alternative is to use compressed air cooling systems using vortex tube technology.
Vortex tubes produce very cold air streams with no external power source. They rely entirely on the work being done by the expanding compressed air to create a temperature differential. The hot air end is exhausted to the factory and the cool air stream injected into the cabinet/ enclosure where it displaces the warm air within which is then also vented to atmosphere. The result is a rapid cooling of the cabinet with no need to deploy powered cooling equipment in the factory all that is required is an air-line.
Cabinet coolers are rated with a certain wattage of cooling power and the cool air streams can be directed to internal hot spots, such as CPU’s, within the enclosure by attachable hoses. Each cabinet cooler is also given an IP rating which will dictate which wet conditions the unit can be used. They can be rated up to IP66 which means they are suitable for use in the presence of sprays and wash down environments
Another advantage of using cabinet coolers is that the enclosure remains at a slightly positive pressure which helps keep it dust free as well.
