HEAT-EXCHANGER Russian patent published in 2005 - IPC

FIELD: heat-exchanging equipment, particularly for machine-tool, chemical, power and other industries to cool process medium.

SUBSTANCE: heat-exchanger comprises cylindrical body with flat closures and removable radiator made as two coaxially arranged coils. Coil ends are fastened to orifices formed in flat closures through boss-like tube plates. Heat-exchanger also has inlet and outlet pipes adapted to supply and discharge working medium. The body is divided into two cavities by partition having central orifice. Installed in the orifice is tube transmitting liquid to be cooled from one cavity into another one and extending along heat-exchanger axis. Coils are arranged in different cavities in opposition one to another. Tube plates of each coil are installed in orifices of one closure. Orifices for inlet and outlet pipes are formed in different cavities near the partition. Cooling medium supply to coils and discharge from the coils in both cavities is carried out trough T-branches installed on tube plates of one of the closures and through kneepieces connected to tube plates of another closure.

EFFECT: increased efficiency of heat removal.
