PTC heater with Al shell for container heat-1

PTC heater with shell

1. Configuration.
Type	Specialty	Excellence	shortcoming	Others
Aluminium shell	Aluminium shell, with wire and insulating film	Fast heat conduct, large power	The shell is electric conductor, may affect the circuit; it’s can not be very small in bulk	Suitable for liquid heating, air heating, heating a surface
Ceramic shell	Ceramic shell, with wire and ceramic insulation	Low cost, small bulk, insulating shell	Not suitable for large power, easy to crack	Suitable for very small bulk, low power
Plastic shell	Plastic shell, with wire and plastic insulation	Low cost, small bulk, insulating shell	Not suitable for large power, and high temperature	Suitable for very small bulk, it can insert on a circuit board
Resin coating shell	Resin coating, with wire, resin insulation	Low cost, small bulk, insulating shell	Very small power, bad heat conduction, low temperature only	Suitable for very small bulk, it can insert on a circuit board
Heater with temperature controller	With a temperature controller to control the temperature of heating object	the temperature of heating objectcan can be ±2℃ of accuracy	High cost, large bulk, more complex structure	Suitable for controlling the temperature in a small range

Other configurations are shown in the picture of “Various kinds of aluminum shells”

2. Some samples of uses.

1) Aluminum shell. It is very easy to fit, constant temperature, safety, long last time. PTC heater is very appropriate under 260℃ temperature. Main appliances: hair straightener, hair curler (crimper), wax melting heater, humidifier, water boiler, liquid warmer, coffee warmer, polymer press-coating heater, hot glue gun, chocolate extruder. Other aluminium shell heater, such as water heater, diesel heater, air heater, hair straightener, hair crimper, see other page in this website.

2) Ceramic shell. It is very appropriate for low power and 50~250℃, Main appliances: mosquito destroyer, aroma emanater, massager, hair straightener.

3. Notice in appliance.

1) After switching on, the initial heating power is large, and then decrease, finally it become steady state. The steady state power depends on appliance conditions. Faster is the heat conduction, higher is the steady state power; higher is the surface temperature, higher is the steady state power.

2) The surface temperature of PTC can be controlled by itself, control circuit and protecting circuit may be omitted in most appliances.

3) The surface temperature increases (or decreases) about 8℃, when supplied voltage increases (or decreases) 2 time.

4) Our PTC products are reliable, long aging, but if they are assembled improperly, the end product may be loose, power or temperature may be instable.

5) Parallel connection is necessary for two or more PTC connection.

4. Current products.

PTC heater with temperature controller

Alumniunm shell, ceramic shell heating element could be controlled by a temperature controller. One type is temperature control type, needed temperature can be set by customer and controlled itself. Another type is voltage adjusting type, the applied voltage can be adjusted lower or higher, and then the temperature will be lower or higher.
