Definitions

  • a large number of recesses extending in the pipe circumferential direction are provided at predetermined intervals in the pipe axis direction with respect to the peaks, and the peaks between the recesses are formed.
  • Each of the fins is configured as an independent fin, and both the bottom cross-section in the circumferential direction of the tube and the bottom cross-sectional shape in the circumferential direction of such a recess are configured to have a curved surface shape. Since both ends of the recess in the pipe circumferential direction are formed so as to gradually narrow and converge, when the absorbing liquid is allowed to flow down the outer surface of the heat transfer tube, such a recess is formed.
  • the shape of the inner surface of the tube corresponding to the ridge in the cross-section in the axial direction of the tube is defined by the cross-sectional shape of the concave portion, and the shape of the outer surface of the tube is inverted. It is one of the desirable and characteristic features that the above-mentioned appearance is exhibited. That is, the concave portion on the outer surface of the tube forms a convex portion or a projection on the inner surface of the tube, and the fin portion sandwiched between the concave portions forms a concave portion on the inner surface of the tube.
  • FIG. 5 is a process explanatory diagram showing the progress of the rolling process on one " ⁇ 3 peaks using a rolled disk.
  • FIG. 9 is an explanatory cross-sectional view of a heat transfer tube installed at an upper part of the absorber shown in FIG.

Abstract

Cette invention se rapporte à un tube chauffant conçu pour des absorbeurs et présentant un accroissement des performances de transfert thermique associé à un accroissement de la surface de transfert thermique, ledit tube étant équivalent à un tube lisse en masse par unité de longueur et n'augmentant pas le coût des matières premières. On fabrique un tel tube chauffant (2) pour absorbeurs de sorte qu'une pluralité de parties formant des crêtes (4), disposées suivant la direction axiale du tube sur une surface externe du tube et présentant une configuration de surface courbe arquée suivant la direction circonférentielle dudit tube, sont agencées de manière à former des vallées (6) entre les parties formant des crêtes (4) adjacentes suivant la direction circonférentielle, on forme des zones irrégulières sur une surface interne du tube que l'on met en correspondance avec les parties en crêtes (4) et les vallées (6), de sorte qu'une matière adsorbante tombe goutte à goutte ou perle sur la surface externe du tube alors que le liquide de refroidissement du tube refroidit la matière adsorbante à l'extérieur du tube. Les parties en crêtes (4) sont munies d'une multiplicité d'évidements (8) espacés les uns des autres suivant la direction axiale du tube et disposés suivant la direction circonférentielle du tube, les deux structures transversales inférieures, suivant la direction axiale du tube et suivant la direction circonférentielle du tube respectivement, présentant des surfaces courbes, de sorte que les parties en crêtes (4) entre les évidements (8) constituent des ailettes indépendantes (10) et de sorte que les extrémités opposées des évidements (8) suivant la direction circonférentielle du tube diminuent progressivement en largeur afin de converger.
