%X 光热利用技术逐步走向成熟，聚光集热是该技术的关键环节之一，分点聚集和线聚焦两种形式，以点聚焦为聚光方式的碟式太阳能系统，具有非常多的优点，如高聚光比、高效率等，其后通常接斯特林发电机，直接发电利用。本文试图在保证聚光集热效率的同时降低系统出口温度，用熔盐换热的方式将碟式太阳能接收的热量导出，并针对不同聚光器直径、聚光比、边缘角、熔盐进出口温度等参数对碟式聚光集热系统的效率和㶲值进行优化分析，找到了最佳工况点，为后续工作提供基础。
The technology of photothermal utilization is gradually becoming mature. Concentrating heat collection is one of the key links of this technology. The dish solar system with point focusing as the concentrating mode has many advantages, such as a high concentration ratio and high efficiency. It is usually followed by a Stirling generator to directly generate electricity. This paper attempts to reduce the outlet temperature of the system while ensuring the thermal efficiency of the concentrating and collecting system. The heat received by the dish solar energy is derived by means of molten salt heat transfer. The efficiency and exergy value of the dish concentrating and collecting system are optimized and analyzed for different condenser diameters, concentrating ratio, edge angle, molten salt inlet and outlet temperature and other parameters, and the best operating point is found, which provides the basis for the follow-up work.
