Air cooling method and requirements
There are many refrigeration methods, and the common refrigeration principles can be summarized into four types: liquid vaporization refrigeration, gas expansion refrigeration, vortex tube refrigeration and hot spot refrigeration. In principle, these cooling methods can be used for air cooling. However, the current methods of cooling air for cutting include indirect cooling methods using low boiling point media such as liquid nitrogen, compressor cycle indirect cooling methods using refrigerants, direct cooling methods using adiabatic expansion of compressed air, and vortex tube cooling methods.
