The surface material of the electric heating film is a special polyester film. The ink line in the middle of the film is made of special conductive ink. It is the core part of the electric heating film and is equivalent to many resistors connected in parallel. It can generate heat after being energized. The silver strips on both sides of the electric heating film are metal current-carrying strips, which are used to connect the ink (resistance) and function like wires. The main materials of metal current-carrying bars are copper tin plating and silver paste. The electric heating film intelligent heating system is manufactured using advanced computer numerical control technology, which can accurately control the thickness of the cured ink on the diaphragm to ensure uniform and stable temperature on the film surface. Low-temperature radiant electric heating film is a translucent polyester film that can generate heat when energized. It is made of conductive special ink and metal current-carrying strips, processed and hot-pressed between insulating polyester films. When working, the electric heating film is used as the heating element, and heat is sent into the space in the form of radiation, so that the human body and objects are warmed first. The overall effect is better than the traditional convection heating method. The low-temperature radiant electric heating film system consists of a power supply, a temperature controller, connectors, an insulation layer, an electric heating film and a facing layer. The power supply is connected to the electric heating film through wires to convert electrical energy into heat energy. Since the electric heating film is a pure resistance circuit, its conversion efficiency is high. Except for a small part of the loss (%), the vast majority (%) is converted into heat energy
Composition and function of the electric heating film system
Electric heating film system It includes the following parts
, insulation layer, reflective film, electric heating film, connecting wires, connecting cards, insulation cover, and thermostat.
Electric heating diaphragm
The electric heating diaphragm is the core component of the entire system and the heating element of this system. Its base material is a special polyester film, the heating element is a special conductive ink, attached with silver paste and conductive metal bus bars as conductive leads, and is finally composited under heat and pressure. The heating of the electric heating film mainly dissipates heat in the form of radiation, which is low-temperature radiation. It is transmissive and transmits heat energy to the room in the form of infrared rays.
Connecting wires, connecting cards, and insulating covers
The connecting wires provide power to the electric heating film and form a loop for the entire circuit. The connecting cards and insulating covers are components of the electric heating film to ensure safe operation.
Thermostat
Controls the entire electric heating film system to ensure the stability of indoor temperature.
Electric heating film connection method
The electric heating film is connected to the thermostat through a connection card. Each group of membranes is connected in parallel. Finally, a group of lines are connected in series to the thermostat. All joints are sealed on the connection card. , there should be no joint points in the wire part
Attached, the connection card installation method
▼The connection card is installed at one end of the electric heating film group (the other end is insulated with special insulating tape).
▼Align the center of the connection card and cover one end of the current-carrying strip. Use the pressure of a special tool to hold it in place.
▼Use special crimping pliers to press and flatten the connection card onto the electric heating film, and use glue for waterproof insulation.
▼Each group of electric heating films is connected in parallel, and is connected to the adjacent film group with a special connecting wire. The connection port is treated with glue for waterproof insulation, and the pulling method is used to check whether the connection of the wire is firm. .
