Spiral Plate Heat Exchangers | Working Principle and Diagrams

Spiral Plate Heat Exchanger

The Spiral Plate Heat Exchanger is based on the principle that increased surface area will make the heating of the fluid faster in comparison to other methods. 

This is actually a family of heat exchangers based on the basic Type A spiral core. A variety of spiral heat exchangers can be created by adding or taking away weld-seams and head arrangements. This versatility makes the spiral attractive to many services and applications.

Example of an actual spiral heat Exchanger.
