Optical Integrator Device with High Energy Utilization Efficiency for High Power Solar Simulator

Abstract

A high-energy-utilization optical integrator device suitable for high-power solar simulators relates to the field of solar simulation technology, and solves the problem of low energy utilization of existing optical integrators, and the increase of energy intercepted by the integrator causes energy waste, resulting in Problems such as the reduction of technical indicators of the solar simulator include opening the interface of the first optical integrator mirror group in the center of the optical integrator mounting plate, and evenly distributing multiple second optical integrator mirror groups around the interface of the first optical integrator mirror group. The interface of the optical integrator mirror group, the interface of the first optical integrator mirror group and the interface of each second optical integrator mirror group and the interface of the adjacent second optical integrator mirror group are provided with a water cooling passage; A plurality of water-inlet water-cooling joints and a plurality of water-outlet water-cooling joints are arranged on the outside of the board, and the water-cooling channels between the interfaces of the adjacent second optical integrator mirror groups are respectively connected with the water-inlet joints and the water-outlet joints. The invention greatly reduces the processing difficulty of the water cooling channel.

Description

technical field [0001] The invention relates to the technical field of solar simulation, in particular to an optical integrator device with high energy utilization rate suitable for high-power solar simulators. Background technique [0002] The development of solar simulation technology is closely related to the development of space science in my country. The solar simulator is a kind of test or calibration equipment that simulates the characteristics of solar radiation under different atmospheric quality conditions indoors. It is mostly used for ground environment simulation tests of space vehicles and has become a space environment simulation test on the ground in my country's space science.
