A heat exchanger includes a body 4 on the surface of which are provided helical or spiral paths 5 which will provide multiple and turbulent flow paths A for a first fluid such as water which is caused to flow through chamber 3 relative to a spirally wound heat exchange tube 6 and in a heat transfer relationship with a second fluid flowing through the tube 6. The tube 6 has one or more further helical or spiral flow paths 9 on its external surface. The multiple flow paths A will extend the residence time for the first fluid within the heat exchanger 1 and this together with the turbulence will maximise heat transfer. Preferably a portion of the first fluid flow will be through a central aperture in body 4 where turbulence is also created by the helical or spiral paths of the tube 6 as it extends through the aperture.
A heat exchanger including a body and at least one first substantially spiral or helical flow path provided for an external surface thereof, the body positioned within a housing to define a chamber between said external surface and an internal wall of said housing, a tube assembly helically or spirally positioned about said external surface, said tube assembly having at least one second substantially helical or spiral flow path provided for its external surface, the relationship between the said at least first and said at least second helical or spiral flow paths being such that a first fluid flowing through said chamber is caused to flow along multiple turbulent flow paths, in heat transfer relationship with a second fluid flowing through said tube assembly.
