HEATING AND VENTILATION PLANT EXHAUST PIPE Russian patent published in 2005 - IPC

FIELD: transport engineering.

SUBSTANCE: invention relates to structural members of heating and ventilation devices used for heating and ventilation of vehicle interiors. Exhaust pipe of heating and ventilation plant consists of exhaust branch pipe of cylindrical form and semispherical protective gas baffle cap secured on exhaust branch pipe. Novelty is that exhaust pipe is provided additionally with cylindrical cup in which said exhaust branch pipe is rigidly secured. Additional semispherical caps are installed one over the other over protective gas baffle cap. Clearance is left between each of additional caps and between protective gas baffle cap and additional cap arranged close to the latter. Additional caps are installed for circulation of air between caps and protective gas baffle cap through holes made in additional caps which are closed to each other and to protective gas baffle cap in end face parts to form spaces. Additional caps are installed so that holes made in one additional cap do not coincide with holes made in other additional cap. Clearance between each of additional caps and between protective gas baffle cap and additional cap nearest to gas baffle cap is within 15-20 mm.

EFFECT: reduced level of thermal notability of object.
