Description PTC heater, using PTC ceramic heating element and aluminum tube composition. This type of PTC heater has the advantages of small thermal resistance and high heat transfer efficiency, and is an automatic thermostat and power-saving electric heater. One of its outstanding features is the safety performance, that is, in case of fan failure stop, PTC heater because of insufficient heat dissipation, its power will automatically drop sharply, at this time the surface temperature of the heater to maintain the Curie temperature or so (generally in the 230 ℃ up and down), so as not to produce such as electric heaters of the surface "red" phenomenon.
