Threaded pipe heat exchanger is one of the mature and efficient
heat exchangers, the series of products are especially designed on
the basis of high thermal load for the users’ convenience. The
inside heat exchange pipes’ inner and outer walls have spiral
corrugation. When cold and hot fluid flows through the inner and
outer walls of the heat exchange pipes, the partial fluid which far
from the pipe wall will keep original flowing state; the rest which
close to the pipe walls will flow spirally with the continually
changed speed and size. In the same time, the spirally flowing
fluid will drive and change the flowing state that be far from the
walls of the pipes; the two sides will affect each other and then
form the strong turbulent flow finally.
