Design method for optimizing light-heat-fluid coupling of solar energy concentration heat collector system

A design method for optimizing light-heat-fluid coupling of a solar energy concentration heat collector system includes: firstly, building a parameterized three-dimensional optical calculating model, a parameterized geometric topological mesh model, a parameterized fluid flow and heat transfer value calculating model and an optimization algorithm model corresponding to the solar energy concentration heat collector system and to-be-optimized parameters thereof; coupling the optimization algorithm model with the parameterized three-dimensional optical calculating model, the parameterized geometric topological mesh model and the parameterized fluid flow and heat transfer value calculating model respectively so as to perform design calculation for optimizing light-heat-fluid coupling; feeding the coupling calculation results back to the optimization algorithm model so as to optimize the design further; and completing the design until the design completely meets optimization judgment standards of selected or desig
