Abstract: The present invention relates to a vortex tube based cooling vest for providing continuous personal cooling to workers operating in high-temperature industrial environments. The cooling vest comprises a counter-flow vortex tube connected to a compressed air source and an integrated airflow distribution network incorporated within a wearable garment. Compressed air supplied to the vortex tube undergoes thermodynamic energy separation to generate a cold air stream without the use of refrigerants, electrical cooling units, batteries, pumps, or moving mechanical components. The generated cold air is distributed through flexible perforated tubes positioned within the garment and directed toward selected body regions including the upper back, shoulders, chest, and abdomen. The system operates at inlet pressures ranging from 4 bar to 6 bar and produces cooling air having temperatures between 20°C and 27°C. The invention provides continuous cooling, reduces heat stress, improves thermal comfort, enhances worker productivity, and offers a lightweight, reliable, environmentally friendly, and safe cooling solution suitable for industrial applications.
