DEFLECTOR FOR EXHAUST VENTILATION PIPE (D) Russian patent published in 2022 - IPC F24F7/02 F24F13/06 F23L17/02 

FIELD: ventilation systems.

SUBSTANCE: invention relates to devices (means) of natural exhaust ventilation systems and is intended to provide inducement of natural exhaust of polluted air due to wind pressure. The deflector for the exhaust ventilation pipe contains a diffuser, a shell, an umbrella-hood with a heat-insulating material and the possibility of placing a protective screen covering the latter. The umbrella-hood is made in the form of a body of rotation, in the form of a hollow double cone, including an outer cone, an inner cone, a common base open from the side of the diffuser, and a cavity formed by the side walls of the inner and outer cones, and the cross section of the double cone by the plane in which its axis of symmetry is located has the shape of a non-convex deltoid. In this case, the mentioned cavity is filled with a heat-insulating material, which is covered by the protective shield type side wall.

EFFECT: creation of a structural design of a deflector for an exhaust ventilation pipe, which has a simpler design while ensuring higher operational reliability.
