Abstract
A flat tube for a heat exchanger may include a longitudinal-end inlet for letting a fluid into the flat tube, and a longitudinal-end outlet spaced apart from the inlet in a longitudinal direction for letting the fluid out from the flat tube. The flat tube may also include flow elements around at least a portion of which the fluid may be flowable around the flow elements in such a manner that the fluid may have a flow direction component perpendicular to the longitudinal direction. The outlet and the inlet each may be delimited on a partial cross-sectional area of the flat tube and arranged diagonally opposite one another.

A flat tube for a heat exchanger, comprising:
- a longitudinal-end inlet for letting a fluid into the flat tube;
- a longitudinal-end outlet spaced apart from the inlet in a longitudinal direction for letting the fluid out from the flat tube, wherein the longitudinal-end outlet is at an end of the flat tube that is opposite that of the longitudinal-end inlet;
- and
- flow elements around at least a portion of which the fluid is flowable around the flow elements in such a manner that the fluid has a flow direction component perpendicular to the longitudinal direction;
- wherein the outlet and the inlet are each delimited on a partial cross-sectional area of the flat tube and are arranged diagonally opposite one another.
A heat exchanger comprising:
- two opposite collectors;
- at least two flat tubes arranged between the two opposite collectors, each flat tube including:
- a longitudinal-end inlet for letting a fluid into the flat tube, the longitudinal-end inlet at a first end of the flat tube;
- a longitudinal-end outlet spaced apart from the inlet in a longitudinal direction for letting the fluid out from the flat tube, the longitudinal-end outlet at a second end of the flat tube that is opposite the first end of the flat tube;
- and
- flow elements around at least a portion of which the fluid is flowable around the flow elements in such a manner that the fluid has a flow direction component perpendicular to the longitudinal direction;
- the outlet and the inlet each being delimited on a partial cross-sectional area of the flat tube and arranged diagonally opposite one another;
- wherein a first fluid flows in the flat tubes and the collectors, and the second fluid flows around the flat tubes.
A flat tube for a heat exchanger, comprising:
- an inlet section running in a first direction containing an inlet for letting a fluid into the flat tube;
- an outlet section running in the first direction and containing an outlet for letting the fluid out from the flat tube, the outlet being spaced apart from the inlet in a second direction transverse to the first direction;
- a heat exchange section arranged in the first direction between the inlet section and the outlet section;
- and
- a plurality of flow elements arranged in the heat exchange section;
- wherein the fluid is flowable around at least a portion of the flow elements in such a manner that the fluid has a flow direction component perpendicular to the second direction;
- wherein the outlet and the inlet are each delimited on a partial cross-sectional area of the flat tube and are arranged diagonally opposite one another, the outlet is at a first end of the flat tube and the inlet is at a second end of the flat tube that is opposite the first end;
- and
- wherein the flow elements are arranged in at least two lines spaced apart in the second direction, each line having at least two flow elements spaced apart in the first direction.
