Description
Technical field
Thereby the present invention relates to a kind of through at high temperature two materials being heated the brazing device that it is bonded together; More detailed; Relate to a kind of on as the steam condensation heat pipe of core component that is applied to the air-cooled type refrigerating module in the extensive generating equipment, the device of brazed aluminum fin.
Background technology
In nuclear power station or thermal power plant, uranium, oil, coal etc. are acted as a fuel and produce heat, and come the water that circulates in the heating system, thereby form steam with these heats.Formed steam generates electricity through the rotary turbine machine, and the steam that has passed through turbine is cooled in condenser and becomes water again.Especially, in the vapor recycle generation mode, need a large amount of cooling waters, therefore use seawater with as the employed cooling water of condenser because water is accomplished the water-cooling pattern of condensation process.Therefore, for the seawater of supplying smoothly and discharge is used as cooling water, thereby be arranged on nearer place, limit off sea usually.
But, at cooling system, and discharge with heated state through the power station as the seawater of cooling water.Now, per hour there is the draining of heated condition about hundreds of tons, that discharge from the power station to be discharged to the ocean.Therefore there is following problem, that is,, ocean temperature risen, thereby cause destroying the environmental problem of marine ecosystems etc. owing to be discharged to the draining of the heated condition of ocean.
In addition, in the country that the major part on territory is made up of land,, therefore, be difficult to water cooled condenser is used as cooling system because it is definitely not enough to be supplied to the amount of cooling water of stram condenser.
Consider these problem points, proposed to use the generating equipment of air cooled condenser recently, and the seawater supply that is widely used in China and the U.S. etc. is also on the generating equipment of ill hinterland.When using these air cooled condensers; Though compare with existing water cooled condenser; Exist the volume of equipment might become big problem, but, therefore compare with using the generating equipment of water cooled condenser owing to also can be arranged on the hinterland that is not the seashore; Has the advantage that to select the address, power station relatively neatly; And the ocean temperature that causes owing to inflow and the outflow do not worried by cooling water rises and causes marine pollution thus, is therefore extensively paid close attention to as the generating equipment of close environment.
A large amount of use heat pipes (tube) in above-mentioned air cooled condenser, and above-mentioned heat pipe can be divided into aluminium bag rectangular tube (AL Clad 0blong Tube) and multirow galvanized pipe (Multi Row Galvanized tube, MRG) heat pipe according to its shape.
Generating equipment has following structure with steam condensation heat pipe, that is, through at the cladding (clad tube) of the range upon range of material of aluminium and steel thus the two sides on the brazed aluminum fin with its structure that is bonded together.Because generating equipment is with steam condensation heat pipe, the outer surface of aluminium is oxidized and its tissue degeneratiaon is an alumdum after soldering, so the surface corrosion more than in air, can not taking place to a certain degree.In addition, because the interface of the aluminium packet materials of the outer surface of aluminium radiator fin and the molten cladding that applies is that therefore the joining tissue of complete metal molten condition can not corrode, thereby but have the advantage of perennity heat transfer effect.
Because compare with columniform small-sized (1 "～2 ") heat pipe of the required vacuum of easy acquisition steam condensation, generating equipment keeps wide cross section more than 5～10 times with the cross section of steam condensation heat pipe, so has the sectional area of relative broad; Thereby; Owing to promptly remove the inner air as non-condensing gas (non-condensable gas) easily, therefore initial device start running is rapid, and; Compare with the heat pipe that the cross section is less; The flow of condensed water is more, therefore, has the advantage that the inner icing phenomenon of condensed water can not take place when turning round in the winter time.
In addition, under the situation of the heat exchanger that uses as tradition, adhere to cold sink with the whole bag of tricks in cylindrical shape heat pipe outside, to improve heat-conducting effect with the MRG pipe heat pipe of heat pipe form.Realize that the method that the metallicity fusion engages has; Utilize the method for metallic resistance welding manner of the same race, and the cold sink of welding, the most approaching with the mode of the effect that can obtain original heat pipe; But in order cold sink to be possessed be suitable for the cross section of resistance welded; And need increase the thickness of cold sink, therefore, are difficult to dispose a large amount of cold sinks.And the reduction of this cooling effectiveness that will cause causing by the minimizing of heat-conducting area.
In order to address the above problem; Make though can insert cold sink on the surface of heat pipe, can have following problem, promptly with (embedded) mode that embeds; Begin to rotate the back under holding state, to be exposed and after having passed through 2～3 months; On the boundary layer between the different kinds of metals, corrode, thereby original function of heat pipe is that capacity of heat transmission reduces rapidly, causes the problem on the performance of entire equipment the most at last.
So far, MRG pipe heat pipe is mainly used in the heat conduction of air cooling heat exchanger both domestic and external, and its reason is, generating equipment is relatively poor with the resistance to pressure of steam condensation heat pipe, and managing heat pipe with MRG, to compare its manufacturing cost higher.But; The condensation of the high more then steam of condensing plant in the generating equipment, vacuum is easy more, and; Vacuum differential pressure can act on steam condensation heat pipe inside in generating equipment; Therefore use heat pipe as the condensing plant in the generating equipment, compare with MRG pipe heat pipe, generating equipment is more excellent relatively with the effect of steam condensation heat pipe.
After nineteen ninety; Especially, the existing generating equipment of being used by American-European countries's exploitation is with steam condensation heat pipe, because the mode of production that falls behind; And the non-yield rate in the soldering operation of aluminium radiator fin and cladding is very high, therefore becomes a key factor that increases production unit cost.
In the prior art; For braze clad pipe and aluminium radiator fin; And dispose the fixing framework of using of steel matter up and down, and the order with aluminium radiator fin, cladding, aluminium radiator fin is configured between this, and at above-mentioned aluminium radiator fin and the opposed part coating of cladding solder flux; Afterwards, put in the electric furnace with steel wire bundle with fixing.So, inner at the electric furnace of high temperature since above-mentioned steel matter fixing aluminium radiator fin is pressed with the deadweight of framework, thereby said aluminium radiator fin is deposited on the surface, upper and lower part of above-mentioned cladding.But when above-mentioned aluminium radiator fin partly was heated excessively or receives excessive power, above-mentioned aluminium radiator fin also might be deposited on the framework except that cladding.At this moment, carry out operation in order to separate aluminium radiator fin and framework with welding gun etc., thereby cause damaged products, and then become the state that can't continue to use.
