"Redness" on the heater surface
It is composed of galvanized outer pressure plate, stainless steel corrugated spring sheet, galvanized inner pressure plate, single-layer aluminum heat sink, PTC electric heating, double-layer aluminum heat sink, nickel-plated copper electrode terminal and pps high temperature plastic electrode sheath. The product adopts U-shaped corrugated heat sink, which improves its heat dissipation rate, combines the advantages of adhesive and mechanical, and fully considers the various thermal and electrical phenomena of ptc heating elements during operation, and its bonding force is strong , Excellent heat conduction 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 electric heater with automatic constant temperature and power saving. One of its outstanding features lies in its safety performance. Even when the fan fails and stops, the PTC heater will automatically drop its power due to insufficient heat dissipation. At this time, the surface temperature of the heater is maintained at about the Curie temperature ( Generally around 250℃), so as not to produce "redness" on the surface of heaters such as electric heating tubes.
