Heat exchangers helical tube support baffles

Smooth high alloy tubes Low-finned tubes Sintered metal tubes Spiral heat exchanger Tube inserts Twisted tubes Helical tube support baffles... 

Although the traditional shell-and-tube heat exchangers have segmental tube support baffles at 90° to the line of the tubes, the helically baffled tube bundle has tube support baffles sloped so as to induce a helical flow pattern on the shell side (see Fig. 27.6).
