摘要： A heat exchanger of the type adapted for use in generating steam in a nuclear power plant, and a method for manufacturing the same. A plurality of curved tubular walls are equidistantly arranged with respect to each other around a central axis with each of these walls having an inner concave side directed toward the axis and an outer convex side directed away from the axis and with each of the walls including an elongated tube having a hollow interior through which a heat-exchanging medium is adapted to flow. Each of the walls further includes a fin structure fixed to the tube thereof at least partially along the tube for forming a vibration-resistant, unitary tubular wall structure. The heat exchanger is manufactured by curving a plurality of finned tubes and welding the tubes to each other to form a tubular wall.

摘要： A tubular heat exchanger which has a structure for relieving stresses which otherwise would occur from temperature fluctuations. A plurality of tubes are connected at their opposite ends to a pair of tube plates which in turn are fixed to opposed enlarged end portions of an elongated vessel which surrounds the tubes and which extends between the tube plates. The enlarged end portions of the vessel are flexible and of a sufficient yieldability to absorb stresses which otherwise would occur due to elongation and contraction of the tubes.

摘要： Heat exchangers having spirally wound tubes for accommodating in their interior an inner heat-exchanging fluid while being engaged at their exterior by an outer heat-exchanging fluid. The spirally wound tubes are arranged one next to the other surrounding a given axis with the convolutions of one tube axially aligned with the convolutions of the next tube. The tubes form a group having an inner region directed toward the latter axis and an outer region directed away from the latter axis. At one of these regions there is a supporting structure while a spacer structure is fixed to the supporting structure and extends between the convolutions of the tubes to form with the latter a unitary assembly of tubes acting as a unitary structure in which the convolutions are maintained at given locations with respect to each other. The spacer structure serves to transmit to the supporting structure the weight of the tubes and the spacer structure as well as any thermal or mechanical stresses or reaction forces resulting from flow of the fluids during operation of the heat exchanger.

摘要： A radial-flow heat exchanger where tubes through which one heatexchanging fluid flows surround a given axis while a second heatexchanging fluid flows across the exterior of these tubes radially with respect to the latter axis. Fluid-guides are provided for this other fluid so as to achieve at the exterior of the tubes a substantially uniform through-flow in all axial sections of the heat exchanger. The fluid-guides may include inner and outer tubular walls which taper in the same direction and define with inner and outer regions of the tubes receiving and discharge chambers for the fluid which flows radially, the receiving chamber having an inlet which forms the largest cross section of the receiving chamber while the discharge chamber has an outlet which forms the largest cross section for the discharge chamber.
