Abstract

The invention discloses a solar heat / electricity combined optical path method, which relates to the field of optics and the field of solar energy utilization. The current distribution can meet the specific needs of different occasions, realize the flexible control of solar light splitting utilization, and use the thermoelectric combined receiver matched with the primary mirror to realize the efficient utilization of the energy flow gathered in the whole area, and solve the problem of energy flow utilization. The efficiency is not high and the conversion efficiency is low, because the processing difficulty of the designed primary mirror free surface concentrator is relatively low, and the structure of the thermal / electrical combined concentrating system is simple, so the reflective thermal / electrical combined concentrating system in the present invention has The basic attributes of compact structure, low processing cost, high system stability, strong reliability, and high total energy utilization rate.

Description

technical field [0001] The invention relates to the field of optics, in particular to a solar heat / electricity combined light path method. Background technique [0002] The full utilization of solar energy plays an important role in energy conservation, emission reduction and promotion of sustainable development. The solar flux density is low and has a dynamic intermittent nature. The concentrating solar power (CSP) system gathers a large area of ​​solar radiation energy in a small range to achieve the purpose of effectively converting high-density energy. [0003] Traditional solar energy concentration systems generally model quadratic surfaces based on geometric optics theory, and directly converge parallel incident rays at the focal point, which is the main form of the current CSP system. However, the free-form surface has no fixed expression, and in the process of its construction, the reverse design is often based on the distribution of the target receiving energy flow...
