Abstract
A spiral heat exchanger is formed of at least two sheets extending along a spiral-shaped path around a common centre body and separated to form at least a first and a second spiral-shaped substantially parallel flow channels extending and enabling flow communication between a radially outer orifice and a radially inner orifice. The centre body includes a wall body with a first conduit at the inner surface of the wall body being in fluid connection to the first flow channel, and a second conduit formed at the outer surface of the wall body and being in fluid connection to the second flow channel.
