Abstract
Based on Matlab heat transferring program and combined with CFX three-dimensional temperature field of thermal conductivity for calculation, included design of pipe network computing plan and three dimensional heat transferring calculation, a guiding blade of high pressure turbine is researched and the cooling structure is designed according to the characteristics of the guiding blade. A high temperature zone about 1 700 K appears on the blade, but the average temperature is about 1300 K, because the trailing edge vortex cooling structure enhances heat transfer coefficient. A good cooling structure design and verifying calculation of temperature distribution in 3 D can be completed on the cooling structure design platform.
