The heat radiators are adhered on two sides of the heating body by heat conductive adhesives. The heating body and internal aluminum bars, the internal aluminum bars and heat radiator fins, and the heat radiator fins and external aluminum bars are all directly connected by the heat conductive adhesives. An original brazing welding mode is improved, and the processing is simpler and has higher efficiency. Lead pollutions caused by brazing welding are prevented, and the adhesive type ceramic PTC heater is more environment-friendly. The adhesive type ceramic PTC heater can be used as an auxiliary electric heater on a split indoor unit of an air conditioner, a cabinet air conditioner, a movable air conditioner, and an air heater. Due to the fact that channels which are originally air gaps are compactly filled by the heat conductive adhesives, the thermal transmission efficiency is higher, and the heating effect is obviously improved as compared with that of other common PTC heaters.

The integral body that aluminum pipe, PTC sheet, electrode and dielectric film the are consisted of setting of exerting pressure obtains above-mentioned heater.
Described PTC sheet two sides evenly are coated with the metal electrode powder, are coated with heat-conducting glue on the described metal electrode powder.
Contact resistance between described PTC sheet and the electrode is 3 to 10 ohm.
Described metal electrode powder is the aluminium powder electrode powder.
Described heat abstractor comprises interior aluminum strip, fin and outer aluminum strip, and the medial surface of described interior aluminum strip and the medial surface of outer aluminum strip evenly are coated with heat-conducting glue, and described fin is bonded on the medial surface of the medial surface of interior aluminum strip and outer aluminum strip by heat-conducting glue.Wherein collision deformation is avoided in interior aluminum strip and outer aluminum strip protection fin two sides.
Described fin is rectangle, U-shaped, waveform or zigzag.
Described interior aluminum strip two ends are provided with the flanging that cooperates with outer aluminum strip; The end face of flanging protection fin is avoided collision deformation.
Described heat-conducting glue is silica gel material; These silica gel material dielectric property are good, heat conduction is rapid.
The beneficial effects of the utility model: the adhesive type ceramic PTC can be used as the environmental-friendly lead-free heating material, uses as electrical auxiliary heater on air-conditioning split indoor set, cabinet-type air conditioner, mobile air conditioner, warm-air drier.Because heat-conducting glue is that the duct of air-gap is filled and to be compacted with many scripts, heat transference efficiency is higher, and heating effect obviously improves than other common ptc heaters.
