Principle of infrared radiationAll objects emit infrared rays, which are essentially a kind of thermal radiation. The higher the temperature of an object, the stronger the infrared energy radiated. The basis of the U-shaped carbon fiber infrared heating lamp is to utilize the thermal effect of infrared rays. When the heating lamp is powered on, the temperature of the carbon fiber element in the lamp rises rapidly and begins to radiate infrared rays outward. As a high-performance material, carbon fiber changes the motion state of carbon atoms and other atoms inside it when it is powered on. Electrons accelerate under the action of the electric field and collide with the lattice, which intensifies the lattice vibration and generates heat. This heat is radiated outward in the form of infrared rays. Advantages of U-shaped designThe U-shaped structural design gives the heating lamp a larger radiation surface area. Compared with traditional straight strip heating lamps, the U-shape can better surround the heated object and provide a more uniform infrared radiation field in three-dimensional space. For example, when used in a printing press to dry ink, the U-shaped heating lamp can irradiate the printed matter from multiple angles, so that the solvent in the ink can absorb infrared energy more evenly and volatilize. This design also increases the effective heating range of the heating lamp. For objects with irregular shapes or certain volumes, the U-shaped heating lamp can adapt to their shapes more flexibly and reduce heating dead angles. For example, when heating a plastic product with depressions or protrusions, the U-shaped shape can bend and wrap around to ensure that these special parts can also receive sufficient infrared radiation for heating.
