The heating principle of the heating element spring heater is mainly based on the heat generated when the current passes through the conductor, and the physical properties of the spring itself.1. Current heating principleWhen the current passes through the conductor (such as the spring), the current will encounter obstacles when flowing in the conductor due to the certain resistance of the conductor, thereby generating heat. This phenomenon is called the Joule heating effect, which is the basic principle of current heating. As a conductor, the spring will also generate heat due to resistance heating when it is energized.2. Utilization of the physical properties of the springThermal expansion:The spring is made of metal, which has thermal expansion. When the spring is heated, the metal wire will expand due to the heat. This expansion not only increases the length of the spring (although the spring may shorten the apparent length due to internal stress during the heating process, the actual length of the metal wire is increased), but also changes its shape and internal stress distribution.During the heating process, this thermal expansion of the spring helps to distribute the heat more evenly because the expanded spring will have a more sufficient heat exchange with the surrounding air or medium.Elasticity and resilience:The spring has good elasticity and resilience, which means that during the heating process, even if the spring expands or shortens due to heat, it can return to its original shape and length once the heating stops and it cools down.This elasticity and resilience allow the spring heater to maintain stable performance during repeated heating and cooling.3. Comprehensive effectIn the spring heater, the heat generated when the current passes through the spring is combined with the physical properties of the spring itself (such as thermal expansion, elasticity and resilience) to achieve the heating effect. When the current passes through the spring, the spring heats up and expands rapidly; when the current stops, the spring cools and contracts. This rapid heating and cooling process allows the spring heater to respond quickly to temperature changes and provide a stable and uniform heating effect.The heating principle of the heating element spring heater is to use the heat generated when the current passes through the conductor and the physical properties of the spring itself (such as thermal expansion, elasticity and resilience) to achieve heating. This heating method has the advantages of fast response and high energy utilization, and is widely used in various occasions that require fast and uniform heating.
