FIELD: heating.
SUBSTANCE: air-cooled heat-reflective head-dress contains intake and plenum valves, circular pneumatic pipeline with adjusting coupling and sprayers for blowing on individual head. System contains plenum cavities for pneumatic pumps of left and right legs, elastic air lines connected through elastic couplings, receiver from elastic material and pneumatic air pressure regulating valve with Rank vortex tube. Air lines from Rank vortex tube with cold and hot air flows are connected to three-way tap. Receiver is connected with outlet pipelines, safety valve and air pressure regulating valve. Air valve, intake valve and air line installed on non-detachable ladder are fastened to shoes sole to fix pneumatic valve.
EFFECT: improves effectiveness of head protection from heat radiation.
