New heating layer and heating method for wind turbine blade mold:

The heating layer is arranged between the inner structural layer and the outer structural layer formed on the surface of the mold master mold;Its characteristics are:
The heating layer includes at least3 sections of heat conduction layers,each section of heat conduction layer is composed of several serpentine-shaped copper guide tubes arranged in parallel at equal intervals and laid flat on the corresponding parts of the blade tip, blade middle, and blade root;
Both ports of the copper guide tubes extend out of the outer structural layer surface to connect with an external heating device;The heating method includes circulating hot water into the heating layer to meet the high-temperature curing conditions of blade products through a water circulation method;By continuously circulating high-temperature water flowing on the mold surface,the temperature requirements for curing wind turbine blade products are achieved. The arrangement of this heating layer improves the molding quality of large blade products,reduces the weight of the mold,has low production cost,and its heating method is safe, stable,and easy to implement.
