TUBULAR HEAT EXCHANGER Russian patent published in 2001 - IPC

FIELD: heat exchange engineering. SUBSTANCE: heat exchanger includes transversely streamlined tube bundle of conusoidal shape and collectors with tube sheets. Tubes of bundle with similar end diameters are located in opposite vertices of rectangle or vertices at base of triangle of tube sheet layout. Element of external tubular surface with different diameter are located in succession in way of flow. EFFECT: enhanced efficiency of heat transfer; reduced mass and usage of metal reduced overall dimensions of heat exchanger. 3 dwg
