Cold Air Gun Working Principle

Looking through the enco catalog i see a cold air gun coolant system for dry machining.

Cold air gun working principle.

How does this. The pressure may reach up to 3 000 psi or about 200 times standard air pressure. It will remove heat to prolong tool life and increase productivity on machining operations when liquid coolants cannot be used. Up until the moment i connected the air supply.

Pressurised gas is injected tangentially into a swirl chamber and. With no moving parts to wear out cold air guns require no electricity at the target just a. I thought they used the vortex principle to separate dense cool from less dense warm air and then discharged them from seperate outlets. Cold air machining eliminates mist coolants and heat related parts growth while improving tool life parts tolerance and surface finish quality.

The high speed air heats up as it spins along the inner walls of the tube toward the control valve. Airflow adjusters sold separately can be switched out to increase or decrease the vortex tube s airflow cfm to alter its cooling capacity. It has no moving parts. A vortex tube creates cold air and hot air by forcing compressed air through a generation chamber which spins the air at a high rate of speed 1 000 000 rpm into a vortex.

Cold air guns cold air guns use filtered compressed air 80 100 psig and vortex tube technology to produce sub zero air for industrial spot cooling. A pcp air rifle works on a very simple principle of air pressure differential. An air gun or airgun is a gun that fire projectiles pneumatically with compressed air or other gases that are pressurized without involving any chemical reactions in contrast to a firearm which pressurizes gases chemically by oxidation of combustible propellants that generates propulsive energy by breaking molecular bonds both the long gun air rifle and handgun air pistol forms. Vortex tubes convert compressed air into a stream of cold air.

The gas emerging from the hot end can reach temperatures of 200 c 392 f and the gas emerging from the cold end can reach 50 c 58 f. With no moving parts to wear out cold air guns require no electricity at the target just a compressed air source. The air consumption range is from 15 scfm to 35 scfm. The vortex tube also known as the ranque hilsch vortex tube is a mechanical device that separates a compressed gas into hot and cold streams.

They have no moving parts for a long service life. Says it produces air 50 colder than air supply. Air that rotates around an axis like a tornado is called a vortex. The cold gun aircoolant system with two cold outlets surrounds a part to be cooled with a stream of clean cold air at 50 f 28 c below supply air temperature.

Use them to keep heat sensitive electronic equipment cool with cold air. With no moving parts to wear out cold air guns require no electricity just a compressed air source. Cold air guns use vortex tube technology and filtered compressed air to produce sub freezing air as low as 30 deg f for numerous industrial spot cooling applications.
