Wind turbine blade is the key component of wind power system. Curing is one of the important processes in its production of large-scale composite wind turbine blade. Mold heating system of circulating water affects the quality of resin curing and the productive efficiency of turbine blade directly. The heat transfer model of heating system for 1.2 MW wind turbine blade is built, and influencing analysis of size parameters on heating effect to mold heating system, such as thickness of heat conduction layer, thickness of insulating layer, inner diameter of parallel pipeline, wall thickness of pipe and distance between pipes are accomplished in this paper. The conclusion provides reference for determining variables and their span of system optimum design.
