Claims

[Scope of utility model registration request]

A flat tube 2 which has headers 1 and 5 at both ends and is bent in a spiral shape so that the width direction is parallel to the core axis and with a space between opposing surfaces, and one end of both the headers 1 and 5 is an outer surface. a casing 3 made of a cylindrical body with both ends closed, in which the flat tube is internally guided so that the flat tube 2 is guided in a liquid-tight manner, and the both ends of the flat tube 2 in the width direction are close to or in contact with the inner surfaces of both ends in the axial direction; , a pair of inlet/outlet pipes 4 opened into the casing 3 near the headers 1 and 5, respectively, and a first heat exchange medium flows into the flat tube 2 via the header 5. The heat exchanger also has a second heat exchange medium flowing through the inlet/outlet pipe 4 into the casing 3 along the curved surface of the tube 2.
