What is a ptc heater?
PTC heater is a kind of heater with automatic temperature control and power saving. It is a heater composed of PTC components as the heat source and aluminum sheet as the radiator through bonding and welding. The PTC heater has the remarkable characteristics of light appearance, rapid heating, safety without open flame, automatic temperature control when the ventilator fails, and long service life.
What is a PTC heater?
As a new type of thermistor material, ptc is mainly used for switching and heating. The use of PTC material has the characteristics of thermal sensitivity, current limiting, delay, etc. and non-contact, noise-free and long service life. It can be applied to refrigerator startup, motor transformer protection, program-controlled switch protection, mosquito repellent, curling hair perm , Electric irons and other small household appliances. Utilizing the characteristics of stable performance of heating PTC, rapid heating, and little influence by power supply voltage fluctuations, various heater products made have become the most ideal substitute products for metal resistance wire heating materials. At present, it has been widely used in heaters, clothes dryers, air curtains, air conditioners, etc.
Principle of PTC heater:
The PTC type ceramic heater is composed of PTC ceramic heating element and corrugated aluminum strip through high temperature bonding. 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 features is its safety performance. In any application, it will not produce "redness" on the surface of electric heating tube heaters, which may cause burns, fires and other safety hazards.
ptc electric heater thermal protector (plastic package), water pump motor thermal protector (plastic package) is a kind of bimetallic sheet after a fixed temperature as a heat sensitive reaction element, when the heat generated by the electric appliance reaches a predetermined temperature value, it will act quickly , Make the contact open, cut off the circuit, when the temperature drops to the preset reset setting value, the bimetallic strip quickly recovers to close the contact and connect the circuit. The thermal protector has a small volume and an insulated shell (PBT high temperature engineering) Plastic), good sealing, flexible installation and other characteristics.
