Abstract
Provided is a fluid heating device that is small in size and capable of heating a large flow of gas or liquid at a low cost. A flow path in which no backwater is produced is provided by providing grooved flow paths of a fluid are provided over an outer side surface of a metallic circular cylinder such that a fluid passing through a narrowed one of the flow paths impinges perpendicularly against a wall of the next flow path. This allows instantaneous heat exchange within a small space, and makes manufacturing of such a structure simple.
