ABSTRACT:
A helical flow heat exchanger comprises a hollow casing with an outwardly protruding helical trough which defines a helical flow path along the internal periphery of the casing. The casing has an inlet at one end for introducing fluid tangentially into the casing and an outlet at another end from which the fluid exits the casing. A blocking body is disposed within the casing to substantially block fluid flow along the length of the casing inward from the peripheral helical flow path and to force fluid that has deviated inwardly back out into the flow path to maintain helical flow.
