Abstract

This paper focuses on the optimization of heat dissipation efficiency in heat-stop of large ground-based solar telescope. The cooling structure of multi-channel loop cooling system for solar telescope CLST with 1.8 meters’ aperture is designed and built in Ansys-CFX software based on computational fluid dynamics. During the optimized simulation of the models, number and position of inlets, coolant flow rate and maximum temperature are taken as variables, constraint and objective respectively. In case of same coolant flow rate, more numbers of inlets and position of inlets are closer to the axis of heat-stop, the maximum temperature on the heat-stop decreases. In the design of CLST heat-stop cooling structure, after arrangement of the number and position of inlets in heat-stop cooling structure, its cooling efficiency increases by 35 percent.
