In this Article developed the heat balance equations for a solar air heater with a concave air pipe absorber, calculating the heat wastes lost from the barrier structures of the device. In addition, a special emphasis is placed on the issues of optimal placement of concave air pipes, optimal distances are selected between the air pipes. Issues of increasing its heat giving capacity are solved by the shading placement of concave air pipes. The result is an increase in the performance of the device by increasing the coefficient of heat transfer of the solar air heater collector with a concave air pipe absorber. To do this, the movement of concave tube absorbers with different geometric arrangements was studied. Also in this article, a heat balance equation was developed to determine the optimal geometric location of air pipes and the reliability of the results obtained was confirmed. According to the simulations carried out, the placement of a concave-tube in the form of a checkerboard on the surface of the absorber is calculated, perpendicular to the air flow, parallel to the air flow and in the form of a flat air pipe.
