Problems solved by technology

However, the existing electric heating film has the problems of low heat radiation efficiency and heat extraction efficiency, and large power loss; at the same time, since the electric heating film is usually placed under the floor, inside the wall or above the ceiling to obtain a soft indoor temperature rise effect , the front and back sides of the electric heating film will have a capacitive effect with the floor, wall or ceiling in contact with it, which will easily cause leakage and lower safety

Abstract

The invention provides an electrothermal film assembly and a manufacturing method thereof. The electrothermal film assembly comprises a first insulating layer, a conductive heat-generating material layer arranged on the upper surface of the first insulating layer, a second insulating layer at least covering the upper surface of the conductive heat-generating material layer, a thermal-radiation reflecting layer arranged at the lower surface of the first insulating layer, a thermal-radiation extracting layer arranged at the upper surface of the second insulating layer, and a thermal-radiation enhancing layer arranged at the upper surface of the thermal-radiation extracting layer. The electrothermal film assembly has the high thermal-radiation efficiency and thermal extraction efficiency; andthe loss of electric energy is reduced effectively. According to the electrothermal film assembly, the outer side of the electrothermal film assembly is packaged plastically by the insulating layers,so that the electrothermal film assembly has the stable electric heating function, the good insulating performance and high safety. Meanwhile, since the thermal-radiation reflecting layer and the thermal-radiation extracting layer in the electrothermal film assembly can be connected with the ground wire of the power source, the capacitance effect formed by the electrothermal film assembly and theoutside can be eliminated and thus the good safe and electric leakage prevention effects are realized.

Description

technical field [0001] The invention belongs to the field of electric heating technology, and in particular relates to an electric heating film component and a manufacturing method thereof. Background technique [0002] At present, the traditional indoor heating is mainly divided into water, steam heating and electrothermal film heating. Among them, the electrothermal film heating method is obviously more popular because of its advantages of less investment, simple maintenance, independent temperature control, and rapid heating. However, the existing electric heating film has the problems of low heat radiation efficiency and heat extraction efficiency, and large power loss; at the same time, since the electric heating film is usually placed under the floor, inside the wall or above the ceiling to obtain a soft indoor temperature rise effect , The front and back sides of the electric heating film will have a capacitive effect with the floor, wall or ceiling in contact with it...
