Abstract (en)
[origin: EP0389970A2] The invention relates to a fin for a heat exchanger having a multiplicity of passages (2) which are intended for accommodating heat exchanger tubes and consist of turned-up collars (3) of oval cross-section. In order to avoid cracks in the collars, in particular given large ratios of the maximum diameter to the minimum diameter, in the region of their small radii the collars (3) have a smaller height than in the region of their larger radii. Moreover, the invention relates to a heat exchanger grid provided with such fins (1). <IMAGE>
