Title (EN) A TUBE SHEET SEGMENT, A HEAT EXCHANGER, AND A METHOD OF MANUFACTURING A TUBE BUNDLE FOR A HEAT EXCHANGER
(FR) SEGMENT DE PLAQUE TUBULAIRE, ECHANGEUR DE CHALEUR ET PROCEDE DE FABRICATION D'UN FAISCEAU DE TUBES POUR ECHANGEUR DE CHALEUR
Abstract: front page image
(EN)For supporting the tubes (1) in a tube heat exchanger there is provided a modular tube sheet segment adapted to fit around one tube and provided with support surfaces for engagement with similar support surfaces of adjacent segments. The outer dimensions and shape of the segment are adapted to precisely provide the desired axis spacing and the desired tube arrangement upon mutual engagement among uniformly shaped segments. Together the segments provide a sheet (12) which meets all the functional requirements of a tube support sheet. The invention further provides a heat exchanger comprising a tube bundle which is put together by arranging tubes with attached segments individually or in layers, and it provides a method of manufacturing a tube bundle which may form part of a heat exchanger.
(FR)Pour soutenir les tubes (1) dans un échangeur de chaleur tubulaire, on prévoit un segment de plaque tubulaire modulaire conçu pour s'adapter autour d'un tube et doté de surfaces de support venant en contact avec des surfaces de support similaires de segments adjacents. Les dimensions extérieures et la forme du segment permettent d'assurer avec précision l'espacement axial et la disposition de tubes voulus, par mise en contact mutuel de segments de forme homogène. Ensemble, les segments forment une plaque (12) qui remplit toutes les conditions fonctionnelles inhérentes à une plaque tubulaire de support. L'invention porte aussi sur un échangeur de chaleur comprenant un faisceau de tubes que l'on constitue en fixant, séparément ou en couches, des segments sur les tubes de segments, et sur un procédé de fabrication d'un faisceau de tubes pouvant faire partie d'un échangeur de chaleur.
