ptc electric heater, also known as PTC heating element, PTC heating element, is composed of selected high-quality PTC heat-sensitive ceramic heating components as the heating source, and is composed of corrugated aluminum strips that are glued, welded and molded at high temperature.
PTC heating has the advantages of constant temperature heating, no open flame (no redness), high heat conversion rate, minimal influence of the power supply voltage, long natural life and other traditional heating components that cannot be compared. Loved by R&D engineers.
ptc electric heaters, PTC heaters, PTC ceramic heaters, duct heaters, PTC duct electric heaters, heaters and high-power industrial hot fans, etc.
PTC heating has the characteristics of high withstand voltage, low residual current, low power consumption, good flame-retardant performance, short response time, and long service life. It uses PTC heating chip as heat source and aluminum alloy corrugated sheet for heat dissipation. The heater is a heater composed of high temperature, bonding, brazing, and molding. Long service life (can be used continuously for more than 10 years), energy saving, no open flame (no redness when heating), no oxygen consumption, high safety performance, automatic heat adjustment and a series of other traditional electric heating devices, such as being less affected by power supply voltage fluctuations Incomparable advantages.
PTC heating element is also called PTC heater, which is composed of PTC ceramic heating element and aluminum tube.
It is composed of galvanized outer pressure plate, stainless steel corrugated spring sheet, galvanized inner pressure plate, single-layer aluminum heat sink, ptc heating sheet, double-layer aluminum heat sink, nickel-plated copper electrode terminal and pps high temperature plastic electrode sheath. Due to the U-shaped corrugated heat sink, the product has improved its heat dissipation rate, combined the advantages of adhesive and mechanical, and fully considered the various thermal and electrical phenomena of the ptc heating element when it is working, and its separation force is strong. , Excellent heat conduction and heat dissipation performance, high efficiency, safe and reliable. 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 characteristics lies in its safety performance. Even when the fan stops running due to a fan failure, the PTC heater will automatically drop its power sharply due to insufficient heat dissipation. At this time, the heater's surface temperature is maintained at about the Curie temperature ( Normally around 250℃), so as not to produce the phenomenon of "redness" such as the appearance of electric heating tube heaters.
