    摘要: A method for determining a stiffness of a tube bundle heat exchanger. The heat exchanger has a core tube and a plurality of coil tubes coiled around the core tube to form a tube bundle having a plurality of coil layers at a respective layer coiling angle. The method determines a geometric strength parameter for a coil layer, the strength parameter being an area ratio of a coil-tube cross-sectional area to a cell cross-sectional area resulting from the axial spacing of the coil tubes and an outer diameter of the coil tubes. The area ratio is corrected by a correction factor taking the orientation of the coil tubes of the coil layer in relation to the force of gravity acting on the coil tubes into consideration. The stiffness of the respective coil layer is determined from the corrected area ratio and a modulus of elasticity of the coil-tube material.

    摘要: A process for determining the strength of a plate-type heat exchanger includes computing the temperature stresses of the plate-type heat exchanger within the heat exchanger during its operation by a three-dimensional numerical simulation. Based on the computed temperature stresses, the strength of the plate-type heat exchanger is determined. The process for producing a plate-type heat exchanger with separating plates and profiles of metal uses this strength determination for establishing one or more mechanical parameters of the heat exchanger. The heat exchanger is manufactured with the one or more mechanical parameters.

    摘要: Plate heat exchanger for indirect heat exchange between at least two liquid and/or gaseous media with an essentially parallelepiped-shaped base (8), means for feeding and removing the media (headers 6, 6a, 7), and a number of passages (14), arranged essentially like stacks, for indirect heat exchange between media that respectively flow into adjacent passages (14), whereby the passages are formed by partitions (1, 22) that are spaced some distance apart, whereby the partitions are spaced some distance apart by end strips (4a, 4b), the passages have a corrugated profile (fins, 2), which is in heat-conductive contact with the partitions (1, 22) at its wave peaks and wave troughs, and the stack is closed off by a cover plate (5, 21), characterized in that the ratio between the width of the partition (B) and the repetition interval of the same characteristic of the corrugated profile as, for example, the repetition interval of two wave peaks (wavelength, LP) has a value in the range of between 15 and 80.
