Today, coil heat exchangers are widely used in various industries. A large number of works have been published devoted to the study of the characteristics of helical coil heat exchangers. According to the authors, conical coil heat exchangers have higher efficiency compared to helical ones. The article investigates the influence of the geometric parameters of conical coil heat exchangers on their effectiveness. The object of study is a conical coil heat exchanger with different tube diameters of the inner coil (di = 13, 15, 17 mm) and various number of turns (N = 6, 10, 14). Modeling was carried out in the Ansys Fluent software package. For each combination of the parameters, data were obtained on the temperature and velocity of the coolant at the outlet. It was found that a change in the number of turns by a factor of 2.3 leads to an increase in the temperature of the heated fluid by an average of 9.7 ° C. The effect of changing the diameter of the inner coil is non-linear.
