Problems solved by technology

However, the electric heating wire is blown during long-term use
It is relatively difficult to detect the fuse position, and it takes a long time to repair it, which will easily cause the mold to be idle, which will seriously affect the normal production
2. The heating control of the electric heating wire is completely controlled by the external control unit and related equipment. Once there is a problem with the control unit or related equipment, the electric heating wire will not work normally and will cause damage to the products in the production process.
3. With water as the heating medium, the scale generated by long-term use will block the heating pipeline, which will affect the normal production

Abstract

The invention relates to a heating layer for a megawatt wind turbine blade auxiliary mould and a manufacturing method thereof. The heating layer comprises at least one heating area, wherein each heating area comprises 5-15 nanometer carbon heating films, a temperature-controlled box, a power supply and a plurality of copper nets; each nanometer carbon heating film is provided with a plurality of small holes; each nanometer carbon heating film is paved on an inner structural layer of the blade auxiliary mould; each copper net is paved between adjacent nanometer carbon heating films; electrodesare arranged at two ends of each nanometer carbon heating film; two electrodes are respectively connected to the temperature-controlled box by power lines; a temperature-limiting line and a temperature-sensing line pre-embedded in each nanometer carbon heating film are connected to the temperature-controlled box; the power lines of the nanometer carbon heating films are in parallel connection with the temperature-controlled box; the temperature-controlled box is used for controlling the temperature of the corresponding heating area; the temperature-control box for each heating area is connected to an externally connected power supply; and all power supplies are in parallel connection and then are connected to a main power line. The heating layer for a megawatt wind turbine blade auxiliarymould can be used for ensuring that the blade auxiliaries are uniformly heated in the process of being solidified in the blade auxiliary mould. The heating layer for a megawatt wind turbine blade auxiliary mould can be widely applied to the field of wind power.

Description

technical field [0001] The invention relates to a heating layer and a manufacturing method thereof, in particular to a heating layer of a megawatt-level wind power blade auxiliary mold capable of providing a curing temperature required for the production of wind power blade auxiliary parts and a manufacturing method thereof. Background technique [0002] Facing the increasing demand for energy consumption and the pressure of environmental protection, countries all over the world are increasing the development of new energy sources. Clean, pollution-free, green and environmentally friendly renewable energy is the focus of energy development in the world today. Wind energy is the most representative type of renewable energy. It is of great significance to protecting the environment and maintaining ecological balance, as well as reducing dependence on conventional energy and improving energy structure. The focus of wind energy development is to use wind turbines to convert win...
