Heating element is a device that converts electrical energy, thermal energy and other energy into thermal energy, which is widely used in home appliances, industrial equipment and other fields. The core principle is to generate heat through resistance (such as resistance wire), electromagnetic induction (such as induction furnace coil) or semiconductor heat generation. Common types include: resistive heating element : such as electric furnace wire, PTC heaters, simple structure, low cost; infrared heating element: heat transfer by radiation, fast warming, high thermal efficiency; electromagnetic heating element: the use of eddy current effect of heat, energy saving and uniform heating. When designing, it is necessary to consider factors such as power, temperature resistance, safety, etc. With the development of technology, new materials (e.g., graphene) are promoting the heating element to upgrade in the direction of high efficiency and intelligence.

Features of the heating element

Heating elements have a number of distinctive features that make them critical in a variety of fields.

The first is the high efficiency of energy conversion, whether it is resistive through the current flow through the resistance to generate heat, or electromagnetic induction using the eddy current effect to generate heat, can convert a larger proportion of the input energy into heat, to meet the demand for rapid warming. Temperature controllability is also an important feature, through the temperature control switch, intelligent control system, etc., according to the application scenarios can be accurately adjusted output temperature, from low-temperature heat preservation to high-temperature heating can be flexibly realized to adapt to home appliances, cooking, industrial heat treatment and other different temperature requirements.

The structure, the heating element has a strong adaptability and diversity, including resistance wire, PTC heaters and other simple and compact structures, easy to integrate into small equipment; and an infrared heating element for radiation heat transfer, non-contact heating can be realized, suitable for specific scenes. Material selection focuses on high temperature resistance, oxidation resistance and insulation, such as nickel-chromium alloy resistance wire can withstand high-temperature environments for long-term work, and ceramic insulating materials to protect the use of safety and extend the life of the element.

In addition, the heating element has good stability and reliability, and in continuous operation, can maintain uniform heat, making it less prone to run over a long time performance degradation. With technological advances, new heating elements such as graphene heaters also show ultra-thin, flexible and bendable characteristics, expanding the application scenarios in wearable devices, special structural space. At the same time, energy saving has become a trend, with high efficiency heating materials and optimized design to reduce energy loss, in line with the concept of green environmental protection, so that the heating element in the enhancement of the use of experience at the same time more sustainable.

Applications of the heating element

In the field of household appliances: stainless steel heating tubes in electric water heaters achieve rapid water temperature increase through resistance heating, providing stable hot water for the family; nickel-chromium alloy heating tubes in ovens ensure the color and texture of baked ingredients through uniform heating characteristics; air conditioner auxiliary heating modules use PTC ceramic heaters to assist in heating in low-temperature environments, which is both energy-efficient and safe. Small appliances such as curling irons and hand warmers rely on flexible heating pads or miniature resistance wires to realize portable local heating functions.

In industrial production scenarios, heating elements are the core temperature control components. Chemical field reaction kettle often equipped with cast aluminum heating plate, through accurate temperature control to ensure the stability of the chemical reaction; semiconductor manufacturing workshop wafer preheating table using infrared heating elements, the use of radiation heat transfer to achieve non-contact rapid warming, to avoid contamination of wafers; heat treatment furnace in the metal processing industry using silicon carbide heating rods, in the high temperature of 1600 ° C continued to work, to complete the metal quenching, annealing and other processes. In addition, the heat bed of 3D printing equipment maintains a constant temperature through resistive heating to ensure uniform curing of printed materials.

The medical and scientific research fields require high precision and the safety of heating elements. Laboratory incubators use thin-film heating pads combined with PID temperature control systems to control temperature fluctuations at ±0.1°C, providing a stable environment for cell culture; medical equipment such as hemodialysis machines use stainless steel armored heating tubes in the pipeline heaters, which are corrosion-resistant and at the same time achieve rapid warming to ensure that the temperature of dialysis fluid meets the needs of the human body; in the case of portable in-vitro diagnostic equipment, the miniature PTC heating element can be used to heat the sample to the required temperature for testing in a short period. In portable in vitro diagnostic equipment, miniature PTC heating elements can heat samples to the required temperature in a short time, improving diagnostic efficiency.

5 FAQs of the heating element

Q1: How to guarantee the safety performance of the heating element?

Overheating protection: built-in thermal protector or temperature control switch, over-temperature automatic power-off. Insulation design: fill with magnesium oxide sand (such as tubular heating tubes), voltage resistance test ≥ 2 kV. Grounding and leakage protection: metal shell grounding, leakage current <0.5mA. Certification standards: household products need to be certified by the CCC, and industrial equipment needs to be in line with the explosion-proof level (such as Exia Ⅱ CT4).
