Cold air gun is very helpful for the application of rapid dry cooling of small local area, such as machine tool head cooling, cooling treatment of various cutter tools, electronic components cooling, the cooling of welding and so on, it is an ideal tool for small area cooling.
Working Principle:
Cold air gun works by inputting compressed air into the vortex tube in a high-speed rotating way. In the course of this gas flow movement, the outer air will be heated, the inner air will be cold. When moving to one end, the air will flow back along the center of the vortex to produce cold air stream whose temperature is lower than the actual temperature of 25 degrees to 45 degrees and hot air below 110 degrees, thus a cooling source is formed.
