Comparing the four heating modes of the electric towel rack, which is safer and more stable: heating tube, alloy heating wire, carbon fiber heating wire, and heating cable?

Heating tube heating Heating tube heating belongs to the heat transfer fluid heating method, which has a simple structure and is easy to maintain and replace. However, due to the use of liquid as the conductive medium, the heating speed is slow, the temperature difference between the upper and lower sides is not uniform, and there is a shortage of hidden dangers of night leakage. In general, the service life and safety are lower than those of dry heating. The main problems are the risk of liquid leakage, slow heating, uneven heating, and low life expectancy. The heating method of alloy heating wire is generally used in stainless steel products. The outermost layer of the alloy heating wire adopts a high temperature resistant silica gel insulation layer. The performance of this heating method is relatively reliable, but due to the characteristics of the alloy heating wire, the capacity per meter is limited, generally no more than 20w per meter. The drying effect is general, but the service life is long. Due to its low power, it is not necessary to use a thermal control system normally. It relies on the balance between its heating power and heat dissipation power to ensure its surface heat, which causes the surface temperature difference of alloy heating wire products to be very large in winter and summer, which is hot in summer and may not be in winter. hot phenomenon. Especially in areas with large temperature difference between winter and summer, carbon fiber heating adopts the technology of double-strand carbon fiber as the heating element, which has a long life and is also a dry heating technology, and there is no liquid inside. It avoids the disadvantage that the power of the alloy heating wire is too small, the same heat dissipation as the heating tube can be obtained, the drying effect is very good, and the indoor heat preservation effect can be achieved. The heating is uniform, the heating speed is fast, and the thermal effect is 30% higher than that of the heating tube, so the heat dissipation of carbon fiber heating with the same power is much higher than that of the heating tube. The carbon fiber heating can adopt the numerical control control scheme, so that the heat of the towel rack can be precisely adjusted. The built-in temperature sensor has no temperature difference in the four seasons, and the performance is stable. The disadvantage is that the assembly process is complicated and the cost is higher than that of the heating tube.
