Vortex generator in the solar air collectors

摘要

The present invention relates to a solar air system comprising : at least one air duct (A, B, C) for heat transfer, having a cross-sectional area of the air duct, wherein the air duct has a fixed cross-section along its entire length, air inlet duct in fluid connection with air duct to supply air to it for heat transfer purposes, having a cross-section of the inlet duct, and fan system in fluid connection with the inlet duct to supply air to it for heat transfer purposes, wherein the fan system is configured to supply an air stream having a static pressure higher than the static pressure of the axial fan, and the system additionally comprises at least one resonator installed in the air duct to change the air flow from laminar to turbulent, and the inlet duct is configured to supply an air stream to the resonator at an angle to the resonator surface, wherein the cross-section of the inlet duct is less than the cross-section of the air duct of the air system. Present invention provides also a method of heat transfer in the system, where the solar air system according to the invention is used.
