An electric heating module structure, an installation method, a forming method, and a wind turbine are provided. The electric heating module structure is configured for melting ice on a blade, and includes an electric heating module, a positive conductive wire and a negative conductive wire. The positive conductive wire and the negative conductive wire are integrally formed with the electric heating module, to supply power to the electric heating module. The integrally formed electric heating module, the positive conductive wire and the negative conductive wire are laid in an outer layer of the blade.
