AIR CONDENSER Russian patent published in 2023 - IPC F28D5/00 F28D5/02 F25B39/00 F25B39/04 

FIELD: heat engineering.

SUBSTANCE: invention can be used in heat exchange devices in which cooling and condensation of water vapour and steam of other liquid media with atmospheric air is carried out. In a steam air condenser, a heat exchange matrix placed in a cylindrical casing, having the shape of a cylindrical ring, is made of a curved sheet with formation of vertical slot channels for the target coolant, which with open sides communicate with the internal cavity of the cylindrical ring of the heat exchange matrix, and sector channels for passage of cooling air, the open sides of which are adjacent to the inner surface of the wall of the cylindrical casing, the heat exchange matrix has upper and lower star-shaped covers, hermetically connected by their contour edges to the walls of the slot channels, the supply pipeline for the target coolant is connected to the upper star-shaped cover and to a perforated distribution pipe, the axis of which is aligned with a common axis of the cylindrical casing and the heat exchange matrix.

EFFECT: simplified design of the device and increased the manufacturability.
