PTC electric heaterAlso called PTC heating element, it is composed of PTC ceramic heating element and aluminum tube. This type of PTC electric heater has the advantages of low thermal resistance and high heat exchange efficiency. It is an automatic constant temperature and power saving electric heater. The outstanding feature of PTC electric heater is its safety performance. Under any application conditions, it will not produce the "reddening" phenomenon of the surface of electric heating tube heaters, thus avoiding safety hazards such as burns and fires.

The PTC electric heater is composed of a galvanized outer pressure plate, a stainless steel corrugated spring sheet, a galvanized inner pressure plate, a single-layer aluminum heat sink, a PTC heating sheet, a double-layer aluminum heat sink, a nickel-plated copper electrode terminal and a PPS high-temperature plastic electrode sheath. This product uses a U-shaped corrugated heat sink to improve its heat dissipation rate, and combines the advantages of adhesive and mechanical types, and fully considers the various thermal and electrical phenomena of the PTC heating element during operation. It has strong bonding force, excellent thermal conductivity and heat dissipation performance, and high efficiency. This type of PTC heater has the advantages of low thermal resistance and high heat exchange efficiency. It is an automatic constant temperature and power-saving electric heater.

PTC electric heaterIt has constant temperature heating characteristics. The principle is that after the PTC thermistor is powered on, the temperature rises by itself, causing the resistance value to enter the transition zone. The surface temperature of the constant temperature heating PTC thermistor will remain constant. This temperature is only related to the Curie temperature and the applied voltage of the PTC thermistor, and has little to do with the ambient temperature. The ptc electric heater is a heating device designed using the constant temperature heating characteristics of the constant temperature heating PTC thermistor. In small and medium power heating occasions, the ptc electric heater has advantages that traditional heating elements cannot match, such as constant temperature heating, no open flame, high heat conversion rate, minimal influence by power supply voltage, and long natural life. Its application in electric heating appliances is increasingly favored by R&D engineers. The constant temperature heating PTC thermistor can be made into a variety of shapes and structures and different specifications. Common ones are disc, rectangular, long strip, ring, and honeycomb porous. Combining the above-mentioned PTC heating elements and metal components can form various forms of high-power Pptc electric heaters.
