This paper considers the main parameters of the solar collector with thermosyphon circulation for the solar heat supply system. There was developed a flat solar collector construction with thermosyphon circulation wherein the heat transfer coefficient is increased by removing the additional partitions between a panel and heat insulation. The solar collector's efficiency reached by the availability of a tank and thermal pump in the construction where a condenser and evaporator executed the form

... f a heat exchanger of «spiral in spiral» type and heat exchanger pipe connections are one above another, which allows increasing the square and heat exchange intensity. The outcome of the study is a description of the mathematical analysis of the heat transmission process in the tank accumulator. We have shown a heat carrier thermophysical parameter dependence on the temperature. the RK. Amirgaliyev Y. is a professor of universities -Al-Farabi Kazakh National University, IITU, SDU. Professor Y. Amirgaliyev's research topics focus on problems in the field of image recognition, image analysis and processing, robotics with machine vision and the development of intelligent systems, as well digitalization of technological processes and objects used in the green energy industry. Fifteen PhD theses were defended under the guidance of professor Y. Amirgalyiev and resulted in practical implementation in scientific and production processes. He has published over 300 research papers, including over 70 papers in the Scopus and WoS databases, H=10.
