Abstract
The article deals with vapor condensation on the surface of cooling element in electrical convection air medium. The characteristics which allow reducing frost formation and increasing aerodynamic properties due to threadlike frost directed growth following its breaking off the cooling element surface are analyzed. Kinetics of threadlike frost formation on cooling element finned surface in electrical convection air medium is estimated on the basis of mass transfer diffuse model for finely dispersed particles of vapor and ice. Estimated trajectories of particles depending on their size, electrical field intensity and air medium velocity are given.

Keywords: frost formation, vapor, mass transfer, cooling element
