Background technique

The advantages that ptc heater is due to its service life length, safety, energy conservation, reliable operation is deeply by electric-heating technology field personnel Like, common ptc heater radiator structure is generally by upper aluminium flake, cooling fin, lower aluminium flake by being welded to form aluminum strip at present Component, aluminum strip component are adhered on aluminum pipe tube body by silica gel, and the height of adhesive strength will have a direct impact on the thermal diffusivity of heater Can, there are aging phenomena for silica gel in the long-term use, and heating properties is caused to be decayed.

Chinese patent application is that CN201210105959 discloses a kind of tubular PTC electric heater, including PTC fever member PTC heater element and electrode strip are packaged and placed on aluminum pipe with insulating materials by part, electrode strip, aluminum pipe, insulating materials and radiator Interior, the tube wall up and down of aluminum pipe is plane, and the tube wall up and down of aluminum pipe is arranged in radiator, and the both ends of tube wall are equipped with four above and below aluminum pipe A flange extended radially out, flange rivet together with radiator.Using this structure, aluminum pipe and radiator are mechanically Connection, realizes good heat dissipation effect.Preferably, by the tube wall at aluminum pipe both ends be set as protrusion triangle, it is trapezoidal or Any one of arc further improves the heat dissipation effect of PTC electric heater.But this kind of equipment still has connection by force Spend low, the more bulky defect of connector.

Utility model content

It is caused by the prior art to solve the purpose of this utility model is to provide a kind of follow-on ptc heater Drawbacks described above.

A kind of follow-on ptc heater, including aluminum pipe, cooling fin and lower aluminium flake, the cooling fin are set in lower aluminium flake, The lower aluminium flake has two pieces to be symmetrically welded the two sides for being fixed on aluminum pipe, and the cooling fin is also integral with Al pipe butt welding fixation, Be equipped with insulating paper on the inside of the aluminum pipe, be equipped with electrode assembly on the inside of the insulating paper, the electrode assembly include electrode plug and Electrode interface, the electrode plug have two pieces it is symmetrical above and below be distributed on the inside of insulating paper, one end of the electrode plug is connected to Electrode interface, is equipped with heater element on the inside of the electrode plug, and the heater element includes potsherd and PTC fever tablet, described Potsherd and PTC fever tablet are spaced apart on the inside of electrode plug.

Preferably, the insulating paper has muti-piece, and the insulating paper is closely set on the outside of electrode assembly, and insulating paper stretches out aluminum pipe There is a distance, insulating paper extend out to the side of electrode interface.

Preferably, the electrode interface is equipped with circular hole.

Preferably, the cooling fin is waveform.

Preferably, described aluminum pipe or so outer wall is recessed inwardly.

Utility model has the advantages that structure is simple, in the long-term use without silica gel aging attenuation problem, reduce Aluminium flake material and bonding silica gel, have saved the cost of material, no silica gel bonding process simplifies processing flow, reduces life Cost is produced, meanwhile, high by being welded to connect intensity, good airproof performance, connector weight is small, high-efficient.
