INLET VENTILATION DEVICE Russian patent published in 2018 - IPC F24F7/00 

FIELD: ventilation.

SUBSTANCE: invention relates to ventilation systems, and more particularly to devices of natural ventilation of premises. Inlet ventilation device consists of an air intake pipe installed in the opening of the enclosing structure and closed with an external end with a grating with an integrated mosquito net, heat exchanger made in the air intake pipe on the side opposite the outer end, the heat exchanger consists of a clamp and a spacer made of resilient stainless materials, a partition separating the spacer from the flange and cups, a partition separating the cup from the lid and the plate, structural elements of the heat exchanger are made assembled according to fig. 2 at a distance multiple of the length of the bushings and fixed relative to each other by at least two screws tightening the heat exchanger structure screwed into the clamp, at that the partitions, the flange, the cups, the lid have air-conducting cutouts, and the bushings, partitions, flange, cups, lid and shield are made of metal with coefficient of thermal conductivity λm>220 W/m*K.

EFFECT: creating a noiseless energy-saving device for natural supply ventilation, that provides heating of air coming from the street due to convective heat exchange with warm air of the room, occurring in the heat exchanger without the use of additional heating devices, executive electromechanisms and regulating manipulations of the user, as well as reducing the number of structural elements in the device (reducing the material consumption), ease of manufacture and installation.
