Abstract. The purpose of the study. Improvement of the design of a vortex heat exchanger used as an element of the room heating system of a gas control point, in order to increase the heat transfer capacity of the heat exchange surface during long-term operation.
Methods. Coating of the inner surface of the swirler blade in a vortex heat exchanger with tantalum oxide in the form of a nanoscale glass-like film to prevent the sticking of contaminants [1, 2].
Results. A technical solution is proposed that ensures the constancy of the flow section of the swirler in a vortex heat exchanger during long-term operation.
Conclusion. The resulting technical solution makes it possible to provide the heat transfer capacity of the heat exchanger necessary for heating systems and to increase the efficiency of its use as an element of the heating system of the gas control room during long-term operation.
