What are the details of the energy-saving far-infrared heating coil?

Energy-saving heating coils now also include nano infrared heating coils, far infrared heating coils, nano heating coils, etc., which are essentially infrared heating coils. After the infrared energy-saving heating coil is connected to the alternating current through the resistor wire, it becomes a far infrared radiation heat source, which has the characteristics of high strength, high thermal efficiency, high penetration, and low energy consumption. The infrared radiation heating technology is pollution-free to both the heated workpiece and the environment. Therefore, the high infrared radiation heating tube is a "green product" in a sense. Its working principle is: when the current passes through the heating wire of the heating tube made of special materials, the heating tube radiates infrared rays of a certain wavelength. When the infrared rays are absorbed by the object, the object is heated. The technology of heating objects with this characteristic is called infrared radiation heating technology. According to the absorption of different wavelengths of infrared light by different materials, in order to adapt to different heated objects, infrared radiation of different wavelengths can be obtained by changing the material composition and winding method of the heated wire.

At present, industrial infrared radiation is mainly short-wave with a wavelength of 0.76~1.6μm, medium-wave with a wavelength of 1.6~4μm, and long-wave with a wavelength greater than 4μm. Short-wave infrared radiation is also called near-infrared radiation, and medium-wave infrared radiation is called far-infrared radiation. The thermal inertia of infrared radiation is very small and the thermal efficiency is very high. Therefore, the use of short-wave and medium-wave infrared radiation technology can heat the workpiece with high density, high energy and high intensity, thereby improving the heating quality, shortening the heating time and saving heating energy. The heating temperature of the Weichuan infrared energy-saving heating coil, which is well-known in the market, reaches 500-700 degrees, and the far-infrared emissivity reaches more than 90%. At the same time, the infrared radiation source material of the Weichuan infrared energy-saving heating coil matches the physical properties of the carbon-chromium-molybdenum alloy material currently used in the injection molding machine, making the energy-saving heating coil have better energy-saving effect than other similar products.

Due to the obvious tendency of full electrification of injection molding machines, the use of servo systems makes the energy consumption of electric heating systems exceed 30% of the total energy consumption. If different types of heating coils can be reasonably selected, energy consumption can be reduced, thereby reducing production costs. The resistive heating coil refers to the heating of the resistance wire, which transfers the heat to the barrel by contact heat conduction. Only the inner wall of the heating coil transfers heat energy, while the heat of its outer wall is mostly dissipated into the air. Due to the problem of thermal balance, the outer surface temperature is consistent with the working set temperature, which is above 200~300℃, and there is a large heat loss. However, the main body of the electromagnetic induction heating coil does not heat up. In actual use, a certain thickness of thermal insulation material will be wrapped outside the barrel. The surface temperature of the barrel of the electromagnetic induction heating coil is lower than 60 degrees Celsius, and the heat radiation in the barrel is very small, the heat energy loss is very small, and the thermal efficiency is very high, so the energy saving effect is obvious. The infrared heating coil is an infrared generator composed of excellent resistors and quartz tubes. It can heat the workpiece with high density, high energy and high intensity. At the same time, it adopts a reflective structure and the application of aerospace-grade insulating materials to improve the efficiency of infrared radiation, reduce heat energy loss, and achieve significant energy saving effects.
