TUBE HEAT EXCHANGER Russian patent published in 2003 - IPC

FIELD: heat exchanging equipment, applicable for manufacture of heat-exchanging apparatuses and devices of transport, power and domestic designation. SUBSTANCE: the tube heat exchanger has a transversely steamplined tube bank with a staggered or corridor arrangement, headers with tube sheets, at a staggered arrangement the axes of the adjacent, monotypic tube end sections-bends coincide with the vertices of the triangle of break-up of the tube sheets providing for minimized tube spaces, the tubes are made with an outer surface divided in length into equal sections-bends of a permanent diameter, with parallel axes, eccentrically arranged relative to one another, inter connected intermediate necks, the alternating sections-bends of the outer tubular surface are successively arranged in the direction of flow of the heat-transfer medium, besides, at a corridor arrangement of the bank tubes the axes of the adjacent, monotypic end sections-bends coincide with the vertices at the opposite horizontal bases of the parallelogram of arrangement of the tube banks providing for equiflow sections in the direction of flow and minimized tube spaces. EFFECT: enhanced efficiency of convective heat transfer, reduced specific quantity of metal per structure and reduced volume of the heat exchanger. 5 dwg
