Abstract
1484505 Heat exchange tubes MODINE MFG CO 22 Jan 1976 [6 June 1975] 02516/76 Heading F4S A heat exchange tube 10, through which flows heat exchange liquid 11, contains a turbulator 17 in the form of a helical strip of expanded metal adjacent the tube's inner surface. The side edges of the strip have integral projections (21 or 31), Fig. 1 or 4 (not shown), which contact the tube's surface and project in directions such that they space the remainder of the strip from the tube's surface. The turbulator directs a portion of the flowing liquid in the tube towards the tube's surface. As shown, the side edges of adjacent coils of the helical strip are spaced from each other but the helix may be such that these side edges contact each other, Fig. 6 (not shown). The tube may have exterior fins (15), Fig. 6 (not shown).
