Abstract
The utility model discloses a vortex tube temperature controller used for positive pressure air breathing apparatus, which comprises a vortex tube provided with a vortex flow generating device, wherein the generating end of vortex flow on the vortex flow generating device on the periphery of the vortex tube is communicated with an air inlet male joint, a bottom cover, a controller main body, an air-flow insulating pipe, an air-flow dispensing block and an air-flow control block. The vortex tube generates vortex flow, after separating cold and hot air, the cold air flows to the air-flow dispensing block in the controller main body through the inner space of a rear cover and peripheral through-holes of the vortex tube, the hot air flows to the air-flow dispensing block through the air-flow insulating pipe, and the air-flow control block proportionally controls the mixed clod and hot air flowing from the air-flow dispensing block. The vortex tube temperature controller forms an inner and an outer air passages through the insulating pipe for separating cold and hot air, proportionally mixes the cold and hot air to regulate the temperature of the air for people breathing, and simultaneously prevents loss of air in the hot air end, which saves compressed air supply.
