[0003] But at the same time, according to the requirements of modern production quality management, the trough-type concentrator thermal power generation device has its disadvantages that cannot be ignored: compared with the dish type and tower type, the collector not only has a longer flow path, but also heats and absorbs heat. It is continuously heated throughout the flow process, which leads to the unbalanced distribution of the temperature and specific gravity of the heat-absorbing working medium, which causes a large loss of heat in the process of exchange and long-distance transmission, thereby reducing the heat utilization rate, etc.
Subsequently, a certain irregular turbulent flow is generated in the heat collecting tube, thereby destroying the order of the flow and increasing the resistance and reducing the uniformity of heat absorption
