Abstract (en)
To provide a flat tube for heat exchange that can ensure a target pressure-resisting strength and in which thinning is achieved. A flat tube (1) for heat exchange is a flat tube (1) for heat exchange in which plural through holes (3) with circular cross-sections through which refrigerant passes are arranged in one row. If t1/R is a value in which a thickness t1 of partition portions (4) partitioning adjacent two of the through holes (3) has been made dimensionless by a radius R of the through holes (3) and t2/R is a value in which an outer peripheral thickness t2 that is a thickness from a flat surface of an outer periphery of the flat tube (1) to the through holes (3) has been made dimensionless by the radius R, in a case where the internal pressure of the through holes (3) is 10.0 to 90.0 MPa, the relationship of 0.28 < (t2/R)/(t1/R) < 0.42 holds true.
