Description

Prefabricated heating mat and method for manufacturing the same

The present invention relates to a prefabricated heating mat and a method for manufacturing the same, which is used for heating by being assembled to the floor or wall of a building.

Prefabricated heating panels or heating panels for heating with electricity as energy are already widely used.

Typical heating panels are manufactured by arranging heating elements, which are heating elements, in solid insulation panels in a manufacturing plant. Such a common heating panel is produced by standardizing to dozens of different sizes to combine the matrix in various construction areas. When constructing such a general heating panel, grasp the specifications of a number of heating panels combined with the construction area, secure the construction of the standard product, and fill the gap with the insulation of the same thickness after filling the gap area without the standard product. Connect the wires in parallel to the heating panel.

However, the heating panel using the heating wire has a low heat transfer efficiency, a long time for heating, and increase the production cost and logistics costs for producing standard products of various sizes, especially heating using the heating wire is electromagnetic waves Due to a lot of problems affecting health is increasingly being used to avoid.

In order to solve the problem of the heating panel, a film heater, which is a planar heating element that emits far infrared rays, has been developed and widely used. The film heater is manufactured in the form of a roll in which carbon particles, which are high resistors, are coated in a parallel thin wire shape on the PET film, and electrodes are formed on copper wires at both ends. Such a film heater is a far-infrared heating element in which heat is emitted by carbon particles when power is supplied to both electrodes.

The film heater has a uniform heat dissipation in the entire film compared to the general heating wire heating panel, and can feel the warm radiant heat by the far-infrared radiation effect, saves electricity costs, generates little harmful electromagnetic waves, and has excellent smoothness and durability.

When heating a general film heater, first, the insulation is attached to the floor of the building, and the film heater wound in a roll shape is arranged on the insulation.
