CONTACT HEAT-EXCHANGE HEATER AND CONTACT JET NETWORK HEAT-EXCHANGER Russian patent published in 2007 - IPC F28C3/06 

FIELD: power engineering, possible use in contact heat-exchanging apparatuses.

SUBSTANCE: in the heater, mixing chamber is connected at inlet to end cylindrical chamber for turbulization of liquid substance flow, and at outlet end it is connected to diffuser branch pipe with pressure decreasing unit and dissipative head for final condensation of steam-liquid substance. A contact jet network heat exchanger is also claimed, in which contact heat-exchanging heater is mounted in the body with a gap relatively to internal diameter of heat exchanger body for division of network water flow onto internal one, passing through heater, and external one, streaming the heater on the outside, while the mixing chamber is connected at inlet to end cylindrical turbulization chamber for internal flow of network water, and at outlet end the chamber is connected to diffuser branch pipe with pressure decreasing unit and dissipative head for final condensation of steam-liquid substance.

EFFECT: increased efficiency, increased reliability, expanded area of possible use.
