Vortex tube coolers will do exactly this. They are powered by standard vortex tube technology and so produce very cold air streams which are direct to the target point by adjustable air hoses.
Reliability and Maintenance
When compared to blower systems enhanced compressed air cooling systems are very easy to maintain. Vortex tube powered coolers have no external power source or moving parts are so are equally reliable and maintenance free.
The simplicity of these systems means they can be deployed in areas that would preclude the deployment of powered blowers. In dirty, wet or humid areas of the production facility any powered equipment requires often costly protection to prevent it breaking down. This may involve water proofing or additional filtration / dust protection. Compressed air systems require none of this and so, in such environments, they are intrinsically more reliable.
