An empirical dependence for calculating the efficiency factor of a flat rectangular fin, located on the straight sides of the flat-oval tube, taking into account, apart from the known parameters the length of the contact line between the fin and the carrier tube are proposed. The dependence can be used to calculate heat transfer coefficients for packages of flat-oval tubes with incomplete fins when designing new highperformance heat exchangers.
