HEAT EXCHANGER Russian patent published in 2021 - IPC F28D3/02 F28D7/10 F28F1/42 

FIELD: heat exchange.

SUBSTANCE: invention relates to heat engineering and can be used in heat exchangers. Heat exchanger comprises housing equipped with manifolds with pipes for supply and removal of first heat carrier and nozzles for inlet and outlet of second heat carrier from housing, and in housing cavity there is a bundle of direct heat exchange tubes with tube grids and screw partitions. Heat exchanging pipes are made coaxial, and the ends of internal pipes are tightly fixed in tube grids, and ends of external pipes are tightly fixed in partitions installed between tube plates, perpendicular to bundle of heat exchange tubes. Screw partitions are arranged in inner tubes cavity, in circular gap between walls of heat exchange tubes and in sections of external surface of internal pipes between tube plates and partitions.

EFFECT: technical result is higher efficiency of heat exchanger.
