Abstract
The surface temperture of Open Large-Aperture Solar Telescope's primary mirror can vulnerablely be warmed too high by exposure to direct sunlight. If its temperature over the external environment is too high, it is likely to decline the mirror seeing. So generally keeping the surface temperture of primary mirror same as the environment's is very important by cooling technology researched. By using Ansys software to analyze a meniscus-shaped aluminum metal primary mirror with a diameter of 2.5m, and thickness of 4.45cm to gain the primary mirror's temperature distribution in order to verify the feasibility of methods of cooling. Furthermore form a more perfect cooling project. Thus it can provide a technical guidance for Large-Aperture primary mirror's development in the future.
