Claims

[Scope of utility model registration request]

(1) In a heat exchanger that allows a fluid to be heat exchanged with the fluid to flow through a space inside a hollow body disposed in a fluid passage, an outer fin is provided on the outer periphery of the hollow body, and an outer fin is provided on the outer periphery of the hollow body. A heat exchanger characterized in that an outer fin portion located on the fluid collision side of the fluid passage has a large surface area, and an outer fin portion located on the side opposite to the fluid collision side has a small surface area.

(2) an inner passage extending in the fluid flow direction through the center by an inner cylinder disposed inside the hollow body and forming a double cylinder structure with the hollow body; and an inner periphery of the hollow body; and an outer passage extending in the fluid flow direction through the outer periphery of the inner fin and the inner fin arranged to connect the inner fin and the outer periphery of the inner cylinder. Heat exchanger as described.
