TEMPERATURE STRATIFICATION PIPE (VERSIONS) Russian patent published in 2025 - IPC F25B9/00 

FIELD: mechanical engineering.

SUBSTANCE: disclosed is the temperature stratification pipe, which contains at least three concentrically arranged heat-conducting pipes, an inlet separation chamber for the gas mixture flow separation along the subsonic and supersonic channels between the pipes, a diffuser at the outlet of the gas stream from the channels, a collector for outlet of gas streams after the diffuser. External straight tube and adjacent shaped tube form one subsonic channel for gas mixture flow, and at least two adjacent shaped tubes form supersonic channels; at that, critical sections in supersonic channels are displaced along the device axis. As a version of the device, the geometry of the device with a central shaped body for creating a supersonic channel is described.

EFFECT: high coefficient of thermal efficiency and high coefficient of adiabatic efficiency.
