FIELD: power engineering.
SUBSTANCE: heat exchanger comprising a twisted pipeline, supplying a fluid working medium to the heat exchanger, a helical axis of horizontal direction and parts of the twisted pipeline arranged on the top and bottom from the helical axis. In accordance with this invention the helical pipeline provides for a double-section passage circuit, besides, the first passage circuit having large dimensions is designed for the working medium of the heat exchanger, and the second smaller circuit of passage is designed as a ventilation circuit. At the same time for each spiral passage in the upper part of the helical axis on a part of the twisted pipeline there is at least one hole for air exhaust, which connect to each other the first and second passage circuits.
EFFECT: provision of maximum possible ventilation for a heat exchanger with a pipeline of twisted type and a horizontal helical axis.
