Abstract

998,021. Tubular heat exchange elements. P. LEGRAND. Nov. 1, 1961 [Nov. 23, 1960; June 7, 1961], No. 39132/61. Heading F4S. A heat exchanger comprises a nest of parallel tubes 1, 2, forming a regular mesh pattern, having formed on their outer surfaces transverse grooves or splines or threads; and spiral-forming or twisted longitudinal elements 3, 4, 5 arranged in the meshes such that the elements disposed in two adjacent meshes have opposite spirals. In one embodiment the elements consist of flat strips (Fig.. 5 and 6, not shown) having on both or either face deflector forming projections 27 obtained by a punching operation, the strips then being twisted. In an alternative form the elements consist of three twisted flat strips interfitted in each other by means of transverse notches (Fig. 9, not shown). The three twisted flat strips are preferably of the same pitch and parallel to each other and rigid elements formed by said strips may be used as longitudinal tierods, stiffeners or vibrating-damping elements. The nest tubes may have a longitudinal groove extending along their outer edge in order to scavenge fluid from the grooves or spines &c. In a further form, the elements may consist of cylindrical bodies on which a twisted tape or wire or metal braid is coil wound. The cylindrical bodies may consist of tubes similar to the nest tubes, the fluid flowing through the next tubes also flowing through the cylinder bodies. In this form the twisted tape &c. contacts both the walls of the adjacent nest tubes and also the walls of the tape carrying tubes of the adjacent meshes. With this arrangement the nest tubes may be arranged into groups of seven, Figs. 14 and 15, in which the tubes are double-walled, the inner tubes 111a, 110a, 117a having constricted or narrow ends to constitute suitable streamlined closing caps 111b, 110b, 117b. The annular space thus formed is of substantially the same crosssectional area as the bent constricted portion welded to the seventh or central tube. The central tube having plain rectilinear and non- constricted end portions. The annular spaces may have twisted strips in them. The cylindrical bodies disposed in the meshes may have any polygonal cross-section, e.g. triangular (see Fig. 16, not shown).
