A kind of electric heater of air conditioner, the electrical heating elements of electric heater comprises electric heating body and the aluminum thermal fin that is positioned at electric heating body both sides, fin surface is formed with anti-corrosion layer, even if fin is formed with ponding, also can not cause corrosion to fin.
Wherein, anti-corrosion layer is the oxide layer that is formed on fin surface.
Or anti-corrosion layer is the dope layer that is sprayed on fin surface.
Preferably, dope layer is teflon layer.
Electric heater as above, fin is arranged into wave-like or rectangle is wavy or rhombus is wavy or be trapezoidally arranged on electric heating body after wavy.
Electric heater comprises many group electrical heating elements, between electrical heating elements, joins by support member, and the two ends of electrical heating elements are arranged on mount pad.
Electric heater as above, in order to ensure the stability of electrical heating elements, the middle part of electrical heating elements is provided with fixture.
Based on the design of above-mentioned electric heater, the utility model has also proposed a kind of air-conditioning, air-conditioning comprises electric heater, the electrical heating elements of electric heater comprises electric heating body and is positioned at the aluminum thermal fin of electric heating body both sides, fin surface is formed with anti-corrosion layer, even if fin is formed with ponding, also can not cause corrosion to fin.
Compared with prior art, advantage of the present utility model and good effect are: the utility model by forming anti-corrosion layer on the fin of electric heater, even in air-conditioning use procedure, on fin, form condensation ponding, the anti-corrosion layer of fin surface also can stop condensed water directly to contact generation chemical reaction with aluminium, on the one hand, avoid the fin aqueous corrosion that is condensed, after dry, produce white powder, and the problem blowing out with air conditioning air flow, can not affect the result of use of air-conditioning; Improve on the other hand the service life of fin.
Read by reference to the accompanying drawings after the detailed description of the utility model embodiment, other features of the present utility model and advantage will become clearer.
