How to detect the exothermic temperature of silicone rubber heaters

In daily life, it is common to conduct installation tests on newly purchased mechanical equipment products, and a simple verification is required before installation to ensure compliance with installation requirements. New energy vehicle battery heater solves the heating system solution for low-temperature environment charging of power batteries: The silicone heating system is a thin and pure resistive heating element, which is very soft and has a thickness of 1.5mm. Silicone rubber waterproof heating pad is a type of thin sheet that generates heat when energized. The core is made of nickel chromium wire or nickel chromium foil etched into a certain shape, so it has high reliability. It is generally printed on insulation materials with any paste such as graphite paste and resistance paste. The silicone rubber heating element is a soft electric heating film element composed of high-temperature resistant, high thermal conductivity, excellent insulation performance, and good strength silicone rubber, high-temperature resistant fiber reinforced materials, and metal heating film circuits. Composed of two pieces of fiberglass cloth and double laminated silicone fiberglass cloth. I would like to share with you the current situation. If the exothermic temperature of the silicone rubber heating strip of the silicone rubber heater can reach the temperature environment required by the equipment, simple testing is required. Here we share with the naked eye the exothermic temperature of the silicone rubber heater.

An important detail parameter of a silicone rubber heater is the surface power of a single head silicone rubber heater. The resistivity is too high, and the surface power will be high when a certain current is introduced; If the resistivity is too low and a certain current is applied, the surface power will be too low. So small diameter and small current are used in low-power electrical appliances, but the current depends on the resistance. The higher the current in a single head silicone rubber heater, the higher the temperature of the single head silicone rubber heater. On the contrary, the lower the current in the silicone rubber heater, the lower the temperature of the silicone rubber heater. The length and diameter of a single head silicone rubber heater were calculated using this method.

Test the surface temperature of the silicone rubber heater to see the color of the silicone rubber heating strip. As the ambient temperature increases, it changes from dark red to slightly bright red, and then from near yellow to slightly white, achieving a dazzling blue white color. According to our social reality, the temperature of the target object can be determined by the glowing color of the object. The single head silicone rubber heater requires a high operating temperature (1100 ℃) and is yellow red in color. The silicone rubber heater controls temperature and higher (1300 ℃), appearing yellow white. Achieve a dazzling blue and white color (1500 ℃) or higher. So the impact of different temperatures on the surface of the silicone rubber heater during system testing is actually a matter of students observing the color changes.
