Many customers don't know what PTC heater is or how PTC heater works, so today we'll give you a brief introduction to PTC heater.
PTC heater
is also known as PTC thermistor ceramics, it is a kind of semiconductor
functional ceramics with positive temperature coefficient. PTC
resistance decreases with the increase of temperature before the
transition temperature. The resistance increases significantly with the
increase of temperature from the transition temperature to the thermal
runaway temperature.
PTC
heater has many advantages, such as constant temperature heating, long
natural life, energy saving, no open fire, good safety performance, easy
regulation of heat and less affected by power supply voltage. Domain.
The PTC heater can be made into various shapes and specifications according to the requirements.
Scope of application:
Heating
fan, air conditioning heating, dryer, mosquito killer, motorcycle
carburetor, automotive damper door, automotive cold start preheating,
electric humidifier, electrical instrument moisture-proof heating plate
(plate), massager, thermotherapy device, melt gun, curling hair, hair
straightener heating, coffee heater, milk heater, boiling water heater,
water heater, steam Beauty, etc.
Production process of PTC heater：
PTC
heater refers to the automatic temperature control PTC ceramic heating
body, is a special ceramic material. The principle of constant
temperature heating of PTC heater is: when PTC heater is energized,
because the resistance at room temperature is small, the initial current
is large, which can make PTC heater heating up quickly, and lead to the
resistance value rapidly increasing into the transition zone. At this
time, the current through PTC heater is very small, so that the surface
temperature of PTC heater remains constant. The temperature is only
related to Curie temperature and applied voltage of PTC heater, but has
nothing to do with ambient temperature. The production process of PTC
heater is as follows:
