Abstract

The invention relates to a fixed-focus aspheric solar concentrator, which includes a spherical reflector, a truss, a driver, a bracket and a control box; wherein, the spherical reflector is installed on the truss, and the spherical reflector is spliced ​​into an integral aspheric concentrating mirror surface , the apex of the spherical mirror is located in the surface of the overall aspheric condenser, so that the normal direction of the apex of the spherical reflector is consistent with the normal direction of the overall aspheric condenser surface at this point; the truss is fixedly connected to the driver, and the driver is installed on the bracket , under the control of the control box, the driver drives the truss and drives the entire condenser mirror to rotate and pitch.

Description

technical field [0001] The invention relates to the field of solar thermal utilization, in particular to a fixed-focus aspheric solar concentrator. Background technique [0002] Solar thermal power generation (CSP) and medium-high temperature heat utilization are important aspects of solar energy utilization. The basic process is: use the solar concentrator to track the sun and converge the solar radiation to the heat absorbing device to obtain high-temperature heat energy, and then use the heat energy for conventional Thermal power generation or other medium and high temperature utilization. Therefore, the solar concentrator is a key component of solar thermal power generation and solar energy utilization system at high temperature. Its optical efficiency and concentration ratio determine the utilization efficiency of solar energy and the maximum temperature that the system can reach. [0003] Solar concentrators can be divided into two types: fixed focus type and follow-u...
