What Is a Vortex Cooler?
A vortex cooler is a small cooler that does not use refrigerants such as chlorofluorocarbons.
The vortex effect, caused by the structure of internal components called vortex tubes, can create cold air as cold as minus 60 degrees Celsius using compressed air. The temperature of the cold air is determined by the cold air ratio on the hot air side. Hot air produced by heat exchange inside the cooler is automatically discharged. Since there are no moving parts, there is no need to worry about breakdowns, and maintenance is not required.
The use of dry, clean air from which impurities have been removed is recommended for stable cool air production.
Applications of Vortex Coolers
Vortex coolers are used for cooling purposes in production sites. Specifically, it is used to cool high-temperature solder, knives, etc., and for rapid cooling during plastic processing. Vortex coolers are also widely used in various other fields, such as cooling electronic equipment and control boxes.
Principle of Vortex Coolers
Compressor air is passed through a tube called a vortex tube, which uses the vortex effect to enable cool air output. No refrigerant or electricity is used.
A special component called a bushing generator in the vortex tube works to rotate the supplied compressed air at high speed. By utilizing the characteristic of air to lose some of its pressure as it expands, the system separates the cold air that has lost heat from the hot air that has absorbed heat.
The outer airflow toward the hot air outlet and the inner airflow toward the cold air outlet rotate in both directions, creating intense turbulence that results in a single mass. Energy is carried from the inner airflow outward as heat, allowing air of different temperatures to be discharged.
