Claims

[Scope of utility model registration request]

(1) An outer tube provided with fins on the outside, and an inner tube inserted inside the outer tube so as to maintain a predetermined distance from the inner wall of the outer tube, and between the outer tube and the inner tube. A heat exchanger characterized in that heat exchange is performed between the refrigerant and the air outside the outer tube or the liquid flowing inside the inner tube by passing a refrigerant through the tube.

(2) The heat exchanger according to claim 1, wherein the inner tube has fins on its outer side that extend along the axial direction of the inner tube and reach the inner wall of the outer tube.

(3) The heat exchanger according to claim 1, wherein the outer tube has fins on its inner side that reach the outer wall of the inner tube and extend along the axial direction of the outer tube.

(4) Utility model registration claim 1, characterized in that the inner tube has fins extending along the axial direction of the inner tube.
The heat exchanger according to any one of Items 1 to 3.
