Abstract
The anticorrosive steel-made radiator is characterized by that at least one kind of metal-anode is inserted into the interior of the radiator, at least part of the anode is immersed in the water,a nd between the anode and radiator it is metallic contact. Said invention uses the method of sacrificial corrosion to prevent the corrosion of steel-made radiator. It is simple in structure, excellent in internal anticorrosive performance, and can raise the use effect of steel-made radiator and steel-made connector and prolong their service life.
Description
The present invention relates to a kind of steel radiator of corroding of can preventing, it is the technological improvement that belongs to the equipment that heats.
Steel radiator is to use more a kind of heating equipment at present, heating equipment adopts open tank, water oxygen level is generally greater than the 0.1mg/ liter, it has caused the corrosion of steel radiator and steel loose mail and joint, time has been grown, wall is bored a hole, and leaks, and some heating sub-district can be missed about 80 tons of water in one day.Because inner corrosion, being not only influences result of use and life-span, and badly other must change by part, causes economic loss in various degree.And, leak and can damage furniture, cause other economic loss.Foreign technology is to take closed system, makes its isolation from oxygen, reduces corrosion, and shortcoming is that its volume is big, and maintenance is difficult, and investment is big.Owing to adopt the foreign technology cost big, and the internal corrosion phenomenon of domestic general use steel radiator is more serious, has influenced the service life and the effect of steel radiator.
The object of the present invention is to provide a kind of employing to add metal anode, prevent the steel radiator that corrodes.This heat spreader structures is simple, utilizes sacrificial anode to come the oxygen in the consumption systems or absorbs oxygen, makes the water of system gradually present alkalescence again and reaches anticorrosion purpose.
The objective of the invention is to realize by following technical measures.
Iron and steel is in water or aqueous environment, and main corrosion is electrochemical corrosion.The metal that electrode potential is lower than iron connects in radiator, constitutes galvanic cell, and the metal of insertion is anode and slowly dissolving, and the iron and steel of radiator has been avoided corrosion as negative electrode, and has obtained protection, has so just formed etch-proof radiator of the present invention.
At the metalwork formation anode of the inner insertion of steel radiator with the radiator unlike material, anode with respect to the current potential of steel radiator be no less than-| 800|mV, between anode and the radiator Metal Contact must be arranged, and anode submerges preferably to small part immersion water.For the enhanced protection effect, also can link between anode and the radiator with a direct current external power supply.Described anode can directly contact with radiator, guarantees the electric conductivity between them, also can have other conductor between anode and radiator, and the connection by other conductor guarantees the electric conductivity between them.The material of described anode can be selected from magnesium and magnesium alloy or zinc and kirsite or electrode materials such as aluminium and aluminium alloy.Described anode can be that integral body is made by electrode material entirely, also can be by rod iron as core, wrap up in electrode material outward and make.Described anode can be that one or more cross section is circle or rectangle or foursquare rod, and sheet or silk are formed, and its diameter, thickness or width generally are not more than 50mm.Anode can be placed on and not add fixingly in the radiator, or described anode and radiator is fixed together.Such as, can be fixed on the vent valve, or be fixed on the plug.
The explanation of accompanying drawing drawing
Accompanying drawing 1 heat spreader structures figure of the present invention
Accompanying drawing 2 radiators of the present invention use anode construction figure
Accompanying drawing 3 radiator anode of the present invention cross section legends
The present invention will be described in more detail below in conjunction with one embodiment of the present invention and accompanying drawing thereof, but the present invention also is limited in the scope of embodiments never in any form, the change on all any structures that does not break away from spirit of the present invention or the replacing of material all should be included in the scope of the present invention.Embodiment
Referring to accompanying drawing 1, be the structure chart of radiator of the present invention.Symbol is respectively radiator body (1) among the figure, plug (2), anode (3), vent valve (4).As seen from the figure, adopt solder technology among this embodiment, anodic bonding is connected on radiator inside, anode metal directly contacts with the radiator metal, and after the radiator water inlet, anode can reach and submerge, wherein the structure of anode (3) is referring to accompanying drawing (2), the centre is steel core (3-1), and the outside is anode material (3-2), and anode material uses magnesium alloy among this embodiment.This embodiment middle-jiao yang, function of the spleen and stomach very cross section is circular rod, participates in accompanying drawing 3.In the galvanic cell of being made up of anode and radiator, the magnesium alloy metal anode that adds in the radiator is dissolved gradually, has protected the radiator metal like this, makes it not to be subjected to corrode, and has prolonged the service life of radiator.
The advantage of anticorrosion heat sink of the present invention is: simple in structure, inner antiseptic property is good; Because it prevents from the corrosion of steel radiator from making radiator system with sacrificial anode protection Middle oxygen consumption, radiator system gradually becomes alkalescence by acidity, and anticorrosion, has increased Service life and effect reduce economy and change mistake.
