HEAT EXCHANGER FOR PNEUMATIC SYSTEMS Russian patent published in 2023 - IPC F28D7/02 F28D7/08 

FIELD: power engineering.

SUBSTANCE: devices for carrying out heat exchange processes associated with pneumatic installations, which can be used in industry, transport and other industries. The pneumatic systems heat exchanger includes a hollow cylindrical body containing a combustion zone and a working zone, while the working zone contains an inlet for a heat exchanger coil installed inside it. The coil-heat exchanger is made of a hollow pipe from a plurality of rows of U-shaped modules with an inlet and an outlet, located one above the other along the height of the working area of the hollow body. Said rows of U-shaped modules are interconnected by connecting elements to form a single pipeline system, each of the rows of U-shaped modules being rotated relative to the next row above it in one direction of rotation. The combustion zone includes at least one fuel supply nozzle, at least one air supply nozzle, and an ignition element.

EFFECT: increase in the energy efficiency of the device, reduction in energy costs, increase of the rate of heating of air in the system, with a simple and compact design.
