Abstract: A heat exchanger for transferring heat between two fluids consists of a shell surrounding at least two tube bundles attached at both ends to a tube header. Each of the tube bundles is constructed from a plurality of individual tubes that are twisted into identical helixes formed about a common helical axis.

Use of multiple tube bundles wound with opposite twist direction improves spacing efficiency between tubes.
