Abstract (en)
A flat tube assembly 1 for a heat exchanger, comprising a flat tube 10 and a fin 20 placed inside the tube 10, the flat tube 10 being formed by a sheet material and being defined by a bottom wall 11, a top wall 12 and two side walls 13, the distance between the bottom wall 11 and the top wall 12 defining the height direction H with tube height Ht, and the distance between the side walls 13 defining the width direction W, wherein at least one of the side walls 13 and a corner section 14 between the bottom wall 11 and this side wall 13 are formed by layers of the sheet material, and wherein the fin 20 is a corrugated sheet with plurality of adjacent walls joined at top and bottom bent portions 22 which are in contact with the top and bottom walls 11, 12 of the tube 10 respectively, the adjacent bent portions 22 being distanced from each other by substantially constant distance T1, wherein a terminal adjacent wall 21 of the fin 10 has a bottom side edge 23 which is distanced from the adjacent bottom bent portion 22, along the width direction W, by a distance T2 which is bigger than distance T1, and is distanced from the top wall 12, along the height direction H, by a distance Hf which is smaller than Ht.
