Claims

[Scope of utility model registration request]

(1) In a heat exchanger in which a fluid to be heat exchanged with the fluid flows through an internal space of a hollow body disposed in a fluid passage, the hollow body is formed to have the same external cross-sectional shape. On the other hand, a heat exchanger characterized in that a portion of the inner circumferential surface of the hollow body other than a portion of the fluid inlet has a structure that increases the surface area.

(2) Utility model registration claim 1, characterized in that a cavity is formed in a part of the fluid inlet on the inner peripheral surface of the hollow body, and an inner fin for increasing the surface area is formed in the other part. Heat exchanger as described in section.
