PTC heater is also called PTC heating element, which is composed of PTC ceramic heating element and aluminum tube. This type of PTC heater has the advantages of small thermal resistance and high heat exchange efficiency. It is an automatic constant temperature and power-saving electric heater. The outstanding feature is the safety performance. In any application situation, there will be no "redness" phenomenon on the surface of the electric heating tube heater, which will cause scalding, fire and other safety hazards. It consists of galvanized outer pressure plate, stainless steel corrugated spring sheet, galvanized inner pressure plate, single-layer aluminum heat sink, ptc heating plate, double-layer aluminum heat sink, nickel-plated copper electrode terminal and pps high temperature plastic electrode sheath. Due to the use of u-shaped corrugated heat sinks, this product improves its heat dissipation rate, and combines the advantages of adhesive and mechanical type, and fully considers various thermal and electrical phenomena of the ptc heating element during operation, and its bonding force is strong. , Excellent thermal conductivity and heat dissipation performance, high efficiency, safety and reliability. This type of PTC heater has the advantages of small thermal resistance and high heat exchange efficiency. It is an automatic constant temperature and power-saving electric heater.
One of its outstanding features is its safety performance, that is, when the fan fails and stops, the power of the PTC heater will automatically drop sharply due to insufficient heat dissipation. At this time, the surface temperature of the heater is maintained at about the Curie temperature ( Generally around 250°C), so as not to produce the phenomenon of "redness" on the surface of heaters such as electric heating tubes. The constant temperature heating PTC thermistor has the characteristics of constant temperature heating. The Curie temperature of the thermistor is related to the applied voltage, but has nothing to do with the ambient temperature.
PTC heater is a heating device designed by using constant temperature heating PTC thermistor constant temperature heating characteristics. In small and medium power heating applications, PTC heaters have the advantages of constant temperature heating, no open flame, high thermal conversion rate, little influence by power supply voltage, long natural life and other advantages that traditional heating elements cannot match. favored by R&D engineers. The constant temperature heating PTC thermistor can be made into a variety of shape structures and different specifications. Combining the above-mentioned PTC heating elements and metal components can form various forms of high-power PTC heaters.
