FIN FOR A PLATE HEAT EXCHANGER AND METHOD FOR PRODUCING SAME

The present invention relates to a fin (103) for a plate heat exchanger having an angular, wave-shaped structure with wave crests (131) arranged in parallel to one another, wherein a wave crest (131)is connected via a wave flank (132) to another wave crest (131), and wherein the wave crest (131) and the wave flank (132) succeed one another in a first spatial direction (D1), and wherein the wave crest (131) and the wave flank (132) are connected to one another by a sheet edge (134). The wave crests (131) have a flat outer surface (135). According to the invention, the outer radius (R101) of the sheet edges (134) is 0.05 mm to 0.18 mm. A method for manufacturing a fin (103) is also provided, which comprises a pressure-shaping step in which a previously provided bent wave-shaped structure (3) is shaped such that the outer radius (R1) of the sheet edges (34) is reduced (R101). 本发明涉及一种用于板式换热器的翅片(103)，具有带棱边的波形结构，该波形结构具有彼此平行的波顶部(131)，其中，波顶部(131)通过波腹板(132)与另一波顶部(31)连接，并且，在第一空间方向(D1)上波顶部(131)和波腹板(132)彼此相继，并且，波顶部(131)和
