Abstract

970,722. Tube-type heat exchangers. P. LEGRAND. Jan. 13, 1961 [Jan. 22, 1960], No. 1573/61. Heading F4S. A heat exchanger comprises a casing (not shown) containing a nest of straight tubes such as T 3 , T 4 , T 5 , having transverse fins 8, and arranged in polygonally-shaped groups (Fig. 1), guide plates P fitted on each tube groups and so shaped to comprise at least one discontinuous helical surface winding about the tube axis and imparting a transverse gyratory motion to the external fluid g, thus forcing it between the tube fins 8, each guide plate P being of polygonal shape with cut-out portions to fit the tubes of a group (see Fig. 4, not shown). As shown, the baffles may be omitted from the tube group at the centre of the nest and, to provide for uniform flow resistance in all the tube groups, these latter tubes t 1 may be larger and more closely spaced than the remaining tubes. The pin shape and spacing may be such that, according to Fig. 5, two complementary vortices j and k rotating in opposite directions are formed between adjacent fins. The tubes of each group may lead to an intermediate header and all the intermediate headers may then lead to a main header (Fig. 1, not shown). Alternatively, all the individual tubes may connect directly to the main header.
