Abstract: Combined with the requirements of wind turbine blade manufacturing parameters and blade mould operation performance, referring to the performance comparison of various aspects of medium and considering the pressure of hydraulic turnover equipment, the cooling medium is selected in this article. Based on the principle of heat balance, the heat dissipation design and analysis of mould cooling are carried out to study the heat consumption of each part of the mould, so as to maximize the rational energy distribution. In addition, considering the original structure and function, the cooling channel is designed, and the model of cooling system is established. The mould cooling cycle monitoring and regulation system based on PLC control was established, and the parameter performance was optimized according to the test results to form a complete cooling system process. Finally, by using ANSYS to check the strength of the mold structure, an electric heating composite mould for wind turbine blade with rapid cooling function was successfully developed.
