PTC heater is also called PTC fever body, which is composed of PTC ceramic fever element and aluminum tube. This type of PTC heater has the advantages of low thermal resistance and high heat exchange compliance. It is an electric heater with automatic constant temperature and power saving. The protruding feature lies in the safety function. In any use environment, there will be no signs of "redness" on the surface of the electric heating tube heater, which may cause burns, fires and other safety hazards.
It is composed of galvanized outer pressure plate, stainless steel corrugated spring sheet, galvanized inner pressure plate, single-layer aluminum heat sink, ptc fever sheet, double-layer aluminum heat sink, nickel-plated copper electrode and pps high-temperature plastic electrode sheath. Due to the U-shaped corrugated heat sink, the product has improved its heat dissipation rate, and summarized the advantages of adhesive and mechanical, and fully considered the various thermal and electrical signs of the ptc fever when working, and its connection force is strong. Excellent heat conduction and heat dissipation performance, high obedience, safety and reliability. This type of PTC heater has the advantages of low thermal resistance and high heat exchange compliance. It is an electric heater with automatic constant temperature and power saving. Its major feature lies in its safety function, that is, when the fan fails and stops, the power of the PTC heater will drop sharply due to insufficient heat dissipation. At this time, the surface temperature of the heater remains at about the Curie temperature. (Usually around 250℃), so as not to produce "redness" signs on the surface of heaters such as electric heating tubes.
PTC heater is a heating device that uses constant temperature heating PTC thermistor constant temperature fever feature plan. In small and medium-power heating places, PTC heating has the advantages of constant temperature fever, no open flame, high heat conversion rate, minimal influence on the power supply voltage, long natural life and other ancient fever components that cannot be compared. The use of electric heating appliances is becoming more and more popular. The love of R&D engineers. The constant temperature heating PTC thermistor can be made into a variety of appearance layouts and different specifications. The more common ones are disc, rectangle, strip, ring and honeycomb porous. Combining the above-mentioned PTC fever elements and metal components can form various forms of high-power PTC heaters.
PTC heaters are divided by conduction method
(1) PTC ceramic heater based on heat conduction. It is characterized by a multi-layered heat transfer layout such as electrode plates (electrical conduction and heat transfer) and insulation layer (electrical insulation and heat transfer) thermally conductive heat storage plates (and some with thermally conductive glue) mounted on the surface of the PTC fever element. The heat emitted is transferred to the heated object.
(2) Various PTC ceramic hot air heaters that conduct convective heat transfer by the formed hot air. It is characterized by high output power, and can automatically adjust the blowing wind and output heat smoothly.
(3) Infrared radiation heater. Its characteristics actually use the heat quickly emitted from the surface of the PTC element or the heat-conducting plate to simply or indirectly cause the far-infrared paint or far-infrared material that touches its surface to radiate infrared rays, which constitutes a PTC ceramic infrared radiant heater.
