Abstract
A new fluid to fluid heat exchanger with the following characteristics has been
developed: Effective, compact, pressure resistant, acceptable pressure drop and
has low weight.
This new type of heat exchanger consists of a flat oval aluminium tube which
has been twisted around its own longitudinal axis. By doing so, the fluids inside
as well as outside will be forced to change position and a turbolar flow pattern is
likely to occur and a better heat transfer coefficient will be obtained. By twisting
the flat oval tube the surface will be somewhat extended.
By twisting the flat oval tube the resistance against pressure will increase
progressively with an increasing twist angle (patent pending)
This solution is obvious, where an efficient, compact and cost competitive
