PTC Heater
Darui Electric recommends for you
The company uses technology to produce PTC heaters, which are divided into cable type and terminal type, etc. They are composed of PTC heating elements and corrugated aluminum strips bonded with high-temperature adhesive. This type has the advantages of low thermal resistance and high heat exchange efficiency. It is an automatic constant temperature, energy-saving electric heater. One of its outstanding features lies in safety performance. Under any application, it will not produce the surface "reddening" phenomenon like electric heating tube heaters, which can cause burns, fires and other safety hazards.
The most notable features are:
1. Cost saving, long life.
Because the heater is not only made of special materials, but also has an integrated chip connected internally, it can control its own heating in real time, avoiding damage caused by excessive temperature, thus giving it a much longer service life than other heaters.
2. Safe, green and environmentally friendly.
The heater body is designed with multiple temperature levels below 200°C. Under any circumstances, the body does not turn red and has a protective isolation layer. No asbestos or other insulating materials are needed for cooling in any application. It can be used with confidence without the risk of burns or fire.
3. Energy saving.
Compared with electric heating tubes and resistance wire heating products, this product relies on the characteristics of the material itself to adjust its thermal power output according to changes in ambient temperature. Therefore, it can optimize and minimize the power consumption of the heater. At the same time, the high heat efficiency material also greatly improves the utilization efficiency of electric energy.
• Rapid heating, self-controlled temperature even when the fan fails, long service life
• Wide voltage range, can be designed according to needs between 12V-380V
• Convenient design, can be designed from small power to large power arbitrarily, and the appearance can also be designed as required
• Non-combustible, safe and reliable, PTC does not turn red or produce open flame when heating
In medium and small power heating applications, PTC heaters have advantages that traditional heating elements cannot match, such as constant temperature heating, no open flame, high heat conversion rate, minimal influence from power supply voltage, and long natural life. Their application in electric heating devices is increasingly favored by R&D engineers.
Usage Notes
(1) PTC heating elements have the characteristic of automatic constant temperature, and their own heating temperature also has a maximum value, which effectively prevents damage to themselves and other components due to excessive heating in electrical equipment.
(2) When PTC heating elements are used to heat liquids (such as water), they will not be damaged after the liquid dries up.
(3) When PTC heating elements are used to heat cold air, they will not be damaged if no air is blown.
(5) Long service life: under normal environment, the life can reach more than 10 years.
(6) Reliable operation: using the internal characteristics of PTC heating elements to control temperature, it will never overheat.
(7) Very wide operating voltage: when the operating voltage changes by 2 times, the surface temperature changes very little.
(9) When multiple PTC heating elements are used together, they should be connected in parallel, not in series.
(10) Different heat dissipation conditions cause great differences in the heating power of PTC heating elements.
(11) The heating power decreases from high to low after power-on, and finally stabilizes. The stable power is related to the use conditions. For the same PTC heater, the power may differ by several times under different use conditions. The faster the heat dissipation, the higher the stable power; the higher the surface temperature of the PTC, the higher the power.
(12) The surface temperature of the PTC heating element is controlled by the PTC itself, or can be controlled by disconnecting the circuit, but cannot be controlled by adjusting the voltage.
(13) The PTC itself has high reliability and long life, but if improperly assembled, the product may experience unstable power and temperature.
