PTC heater adopts element effect, adopts PTCR thermal ceramic element, which is composed of several single pieces combined with corrugated heat dissipation aluminum strip and bonded by high temperature glue. It has the obvious advantages of low thermal resistance and high heat exchange efficiency. Its biggest feature lies in its safety, that is, when the fan is blocked due to a fan failure, the power of the PTC heater will automatically drop due to insufficient heat dissipation. At this time, the surface temperature of the heater is limited to the Curie temperature (usually 220 ℃), so as not to produce the phenomenon of "redness" on the surface of the electric heating tube heater, eliminating the hidden danger of accidents.
Principle and function of PTC heater PTC type ceramic heater is composed of PTC ceramic heating element and corrugated aluminum strip through high temperature bonding. This type of PTC heater has the advantages of low thermal resistance and high heat exchange efficiency. It is an electric heater with automatic constant temperature and power saving. One of its outstanding features is its safety performance. In any application, it will not produce "redness" on the surface of electric heating tube heaters, which may cause burns, fires and other safety hazards. The most notable features are:
1. PTC type ceramic heater saves cost and has a long life. It does not require special temperature controllers and temperature sensors such as thermal resistance thermocouples to perform temperature feedback to control the heating of the heater. Its temperature adjustment is based on its own material characteristics, so that the product has a service life that is much longer than other heaters .
2. The PTC ceramic heater is safe and environmentally friendly. The heater body is designed to have multiple levels of heating temperature below 200 degrees Celsius. In any case, the body does not redden and has a protective isolation layer. Any application does not require asbestos and other heat insulation materials to cool down, so it can be used with confidence. There are problems of burns to the human body and fire.
3. PTC type ceramic heater saves electric energy. Comparing electric heating tube and resistance wire heating products, this product relies on the characteristics of the material itself and adjusts its own thermal power output according to the change of the ambient temperature, so it can optimize the heater's power consumption to a minimum, and at the same time, it is a material with high heating efficiency. It also greatly improves the utilization efficiency of electric energy.
PTC type ceramic heater use attention
1. The PTC heating plate has the characteristics of automatic constant temperature, no temperature control system is needed, and the PTC heating plate can be directly energized.
2. When the PTC heating plate is used to heat liquid (such as water), the PTC heating plate will not be damaged after the liquid is dried.
3. If the PTC heating plate is used to heat the cold air, when the air is not supplied, the PTC heating plate will not be damaged.
4 . Long service life, under normal environment, the service life can reach more than 10 years.
5. Reliable work, using the internal characteristics of PTC heating plate to control the temperature, never over-temperature.
6. The working voltage is very wide: when the working voltage changes 2 times, the change in surface temperature is very small.
7. When multiple PTC heaters are used together, they should be connected in parallel, not in series.
In the occasion of low and medium power heating, PTC heater has the advantages of constant temperature heating, no open flame, high heat conversion rate, minimal influence of the power supply voltage, long natural life and other traditional heating components. The application in electric heating appliances is becoming more and more popular. Favored by R&D engineers.
