Study on Influencing Zone of Thermal Bridge of Corner Column inSelf-insulation System

摘要

The two-dimensional steady heat transfer of corner column is analyzed using ANSYS, moreover, influencingzone of thermal bridge and heat loss in influencing zone is analyzed quantitatively. Research shows that when the thicknessof insulation layer is more than 20mm, influencing zone of thermal bridge is about 160mm, and additional heat flowin influencing zone accounts for more than 20% of additional heat flow in thermal bridge.
