Carbon fiber endows its composite materials with excellent properties due to its inherent characteristics, including high specific strength, high specific modulus, high temperature resistance, corrosion resistance, fatigue resistance, creep resistance, conductivity, heat transfer, and low coefficient of thermal expansion. This provides the possibility and inevitability for its application in the wire and cable industry.

Development and Application of Carbon Fiber Heating Cable:

People have long known that electric heating technology using metal materials as heating elements has been widely applied in various fields. However, metal wires are prone to oxidation on the surface at high temperatures. Due to the continuous thickening of the oxide layer, the effective area for current flow decreases, increasing the current load and making them prone to burning out. Under the same allowable current load area, the strength of metal wire is 6-10 times lower than that of carbon fiber, and it is prone to breakage during use.

Carbon fiber is a hexagonal lattice layered structure composed of graphite, and is a fully black body material. Therefore, in electric heating applications, it exhibits high electric thermal conversion efficiency. Under specific conditions, high temperature does not oxidize, and the load intensity and mechanical strength per unit area of current do not change.

The current applications of carbon fiber heating cables are as follows:

Low temperature radiation heating cable floor heating system.

Thermal insulation heating for constant temperature brooding boxes, flower rooms, nurseries, vegetable greenhouses, etc.

Road snow melting and airport runway snow melting: Ideal products for floor heating in concrete structures, can also be used in snow melting devices to prevent frost on roof rainwater and drainage pipes, and can be used for soil heating.

Pipeline and tank insulation and antifreeze: Electric heat tracing products have been widely promoted and applied in China in recent years. Its application areas mainly focus on petroleum, chemical, power, railway, and civil or commercial buildings. With the development of China's power industry, the market prospects for electric heat tracing products, which mainly rely on clean and pollution-free electricity, are very broad. At the same time, higher requirements have been put forward for the performance of electric heat tracing products.

Soil insulation for football fields, lawns, and public green spaces: Solar water heaters are designed to supplement heat energy when the water temperature of the solar water heater cannot meet the needs of daily life or engineering due to insufficient sunlight during long-term rainy or winter seasons. It has strong resistance to extreme heat, cold, and high temperature and humidity environments, and has the function of preventing dry burning. Even if the water tank is occasionally short of water and accidentally powered on, it will not burn out the electric heater and water tank, ensuring safe use.

Efficient and energy-saving:

The electric heating conversion rate exceeds 98%, which is more energy-efficient than traditional resistance wire heating (conversion rate of about 80%) and meets the "dual carbon" goal.

Fast heating rate:

It can heat up to the target temperature (such as 50 ℃~100 ℃) within seconds, with a faster response speed than traditional PTC heating elements.

Good temperature uniformity:

In the planar heating mode, the temperature difference can be controlled within ± 2 ℃ to avoid local overheating, making it suitable for scenarios that require high temperature accuracy.

High safety:

No open flames, low electromagnetic radiation, and with insulation layer design (such as PET/PI substrate wrapping), it can achieve water and electricity separation.

Strong design flexibility:

Customizable size, shape, and power according to requirements, suitable for special scenarios such as flexible wearable devices and curved heating devices.

At the same time, they will face challenges and opportunities in aspects such as intelligence, customization, energy efficiency, and energy conservation. In this process, continuous technological innovation and market expansion will be the key for enterprises to maintain their competitiveness.

Sensor accuracy:

• Sensor types: Different types of temperature sensors, such as thermistors, thermocouples, etc., have different accuracy and response characteristics. For example, in some high-precision temperature control systems, using a constant current source circuit to drive a thermistor as a temperature sensor can improve measurement accuracy. Thermistors have high sensitivity, but may be affected by environmental factors. Thermocouples are suitable for high-temperature measurement, but their accuracy is relatively low.

Control algorithm:

• PID control algorithm: The PID control algorithm is a commonly used Intelligent temperature controller control algorithm. The adjustment of PID parameters directly affects the accuracy and stability of the temperature controller. For example, in an analog PID circuit, by calculating the error signal to drive the temperature control element, such as a thermoelectric cooler (TEC), precise closed-loop temperature control can be achieved. Reasonable adjustment of PID parameters enables the temperature controller to respond quickly to temperature changes while maintaining stable control accuracy.

Environmental factors:

• External temperature fluctuations: Fluctuations in external temperature can affect the accuracy and stability of the temperature controller. Therefore, designing a high-precision temperature control box to control the temperature of the environment where the absorption cell is located can reduce the impact of environmental temperature on the measurement results.
• Humidity: Humidity may also affect the accuracy and stability of the temperature controller. In some application scenarios, such as greenhouse management systems, it is necessary to comprehensively consider factors such as the temperature outside the greenhouse, wind speed, solar radiation intensity, and indoor humidity, and adopt a fuzzy PID control method to establish a high-precision temperature control method.

Equipment Components:

• Performance of Temperature Control Elements: The performance of temperature control elements directly affects the accuracy and stability of the temperature controller. For instance, the response speed, cooling/heating capacity, and other performance parameters of a thermoelectric cooler (TEC) as a temperature control element will influence the temperature control effect of the temperature control system. Selecting high-performance temperature control elements can enhance the accuracy and stability of the temperature controller.
• Circuit Design: The rationality of the circuit design also impacts the accuracy and stability of the temperature controller. For example, isolating the core analog circuit from the heat-generating components can improve the stability of the temperature control module. Utilizing a high-power constant current source drive circuit to drive the TEC can ensure the stable operation of the temperature control element.
