The fin draws heat away from the ceramic element, transferring it directly to a surface to be heated. As it heats up, the resistance increases and the current draw decreases. uses a similar extruded fin or honeycomb structure with a fan to increase the heat transfer rate. PTC stands for "Positive Temperature Coefficient," which is a reference to the resistance that it takes to put enough energy into an object before it starts to feel like it's heating up, then displays an increase in electrical resistance. This type of PTC heating element has the advantages of small thermal resistance and high heat exchange efficiency, and is an automatic constant temperature and power saving electric heater. In some applications, this self-regulating characteristic allows PTC heaters to be used without thermostats or overtemperature protection circuits.
