Abstract
The utility model discloses a kind of radiator with anti-corrosive metal coating, the radiator includes radiator ontology and is sprayed at the anti-corrosive metal coating in the radiator inner body wall by metal spraying mode.The anti-corrosive metal coating carries out physical shielding to radiator ontology and synergy is protected in negative (sun) pole, substantially reduces the electrochemical corrosion of radiator inner wall, greatly improves the service life of radiator.
Description
Technical field
The utility model relates to a kind of radiator more particularly to a kind of metal spray coating technique is utilized to carry out the warm of inner wall protection
Gas piece.
Background technique
Radiator is a kind of heating equipment, is mainly used in the northern area of winter cold, is had the function of warming.Heating
Piece generallys use cast iron, steel, fine copper, cast aluminium, Bi-metal Steel Aluminum, albronze and is made.
Existing radiator in use, since radiator inner wall is directly contacted with water, causes electrochemical corrosion tight
Weight and oxidation corrosion are serious.In order to extend the service life of radiator, the prior art is using perfusion anticorrosive paint and anode is added
Metal bar carries out anti-corrosion.
Anticorrosive paint is one kind of paint, although playing physically-isolated efficiency, after water impregnates for a long time just
It can fall off, not have anodic protection function, when perfusion needs to carry out heating drying, consuming energy, in addition anticorrosive paint and heating
The combination of piece inner wall is insecure, and uniformity is also bad, and anti-corrosion effect is undesirable always, and to the unshielded effect of electrochemical corrosion.
The anti-corrosion mode of anode metal stick is added although electrochemical corrosion can be slowed down, does not have physical isolation function,
Oxidation corrosion can not be completely cut off, and at high cost, the anode metal stick additionally incorporated corrosion to a certain extent after just will appear fragmentation,
Slag-off phenomenon causes caliduct to block.
It is above-mentioned now all the service life of radiator to be caused at 10 years or less there are two types of anti-corrosion mode.
It can be seen that existing radiator is in structure and use, it is clear that there are still inconvenient and defects, it would be highly desirable to be subject into one
Step is improved.
Utility model content
The purpose of this utility model is that overcoming, anti-corrosion effect present in existing radiator is undesirable, service life is low
Under problem, a kind of novel radiator with anti-corrosive metal coating is provided.
Embodiment according to the present utility model, the radiator with anti-corrosive metal coating include radiator ontology and
The anti-corrosive metal coating in the radiator inner body wall is sprayed at by metal spraying mode.
