Description

technical field [0001] The invention belongs to the technical field of solar energy Stirling heat engine heat absorbers, and in particular relates to a design method for a dish-type solar energy Stirling heat engine tube cluster heat absorber. Background technique [0002] The performance of the heat exchanger assembly of the dish solar Stirling heat engine is the key to ensure the performance of the whole machine. As the interface of light-to-thermal energy conversion, the performance of heat absorber is one of the determinant factors reflecting the performance of heat exchanger components. Compared with heat sinks for other purposes, the technical requirements of heat sinks for solar thermal power generation are higher, which is mainly reflected in the fact that the heat sinks for solar thermal power generation are subjected to greater heat flux density, and the distribution of heat flux density is more uneven and reliable. The performance and maintainability requirements...
