Abstract
A multivane turbulator has been provided wherein at least two "V"-shaped members forming the vanes thereof are disposed with their vertices adjacent one another and twisted about each other such that the pitch of the twist is sufficient to render the turbulator self-supporting with symmetrically disposed vanes about a central axis. The method of forming the turbulators includes the steps of bending at least two strips of flat stock into "V"-shaped members and disposing one adjacent the other at their vertices and twisting same until the vanes are self-supporting.
