The article presents the optimization of the radiant surface of the solar air heating collector (SAH). As a radiation-receiving surface of the SAH, a surface is used, which is a system of metal drainage shavings and a V-shaped surface. Based on the study of the heat transfer process, an effective scheme of heat removal from the radiation-receiving surface of the SAH is presented. When optimizing the radiation-sensing surface of the SAH, the process of radiation-sensing of the surface, which depends on the geometric shape of the chips, is taken as the target function of the maximum. A formula is proposed for calculating the determination of the transmitted amount of the radiant flux of the sun to the unit of the frontal surface through the shape of the metal shavings from the value of the opening step angle in different thicknesses of the metal shavings. It has been confirmed that the solar radiant flux passing to the unit of the frontal surface through the metal chip shape reaches its maximum value in the following cases: when the chips are 0,002 m thick, they have an optimal angle φ = 58°, the transmitted energy of the radiant flux through the chip shape is E = 31%; with a chip thickness of 0,0005 m, the optimal angle is φ = 42°, the transmitted energy of the radiant flux through the chip shape is E = 41%; with a thickness of 0,001 m, the optimal angle is φ = 50°, the transmitted energy of the radiant flux through the chip shape is.
