Description
The invention relates to the technology of heating and UTILIZATION OF VESIDUAL HEAT IN aspect.
Radiator is used very wide aspect industrial heat exchange and civil heating.Many in recent years new inventions make radiator increase compressive resistance to improving the thermal efficiency, strengthen decay resistance and reduce metal material consumption, and directions such as expansion function of use develop.As " corrugated type radiator " (Chinese patent application number 86201952, classification number F28D1/06); " flanging steel column radiator " (Chinese patent application number 86208015, classification number F24D19/00); " cast iron sheet-type radiator " (Chinese patent application 86203729, classification number F28D1/00); " dual purpose heat radiator " (Chinese patent application 86200060, classification number F24J2/04).The characteristics of these radiators are that heating agent is directly flowed through and is full of radiator inside, and corrosivity that it is entrained and fouling are difficult for eliminating.
The successful Application of " heat pipe " this superconduction hot body of utilization phase transition of vacuum two phase flow principle has driven the invention of many patents in the thermal technology field.As " cluster type heat pipe " of the U.S., " separate heat pipe " of Japan, " the finned heat-pipe radiator " of domestic application etc.High heat transfer coefficient under the gentle low temperature differences such as the common feature of these inventions is and the big heat that transmits.But at present " heat pipe " also inconvenience be common in the system such as various steam and hot waters.
The applicant imagines a kind of new radiator, makes its tool efficient heat transfer radiating principle, and very the light material consumption is few for wall, the high long service life of compression resistance.Through research of the study over 8 years and unremitting test, trial-produce successfully finally.
Purpose of the present invention provides that a kind of thermal medium and internal pressure and heating system separate, and can bear the high-efficient energy-saving radiator of higher operating pressure.
Another object of the present invention is further to reduce the metal material consumption of radiator.Improve radiator resistant to rust resistive connection dirt freezing tolerance, prolong its service life, guarantee its usage safety performance.
The 3rd purpose of the present invention is in order to enlarge the scope of application of " heat pipe " and " vaccum phase conversion heat exchanger ".
This radiator be with some columnar metal pipes vertical side by side with up and down each one be welded into a column comb level communicating pipe, become radiator body by monolithic or several piece column comb assembly welding.One or two the straight garden of metal pipes pass lower body part level communicating pipe and with its joint, two ends sealing, this is an isolated tube.Be through on the isolated tube outer surface in level communicating pipe and be covered with porous layer alveolation imbibition core.Put the row's of vacuumizing fixed gas dual-purpose valve at main body top one end, the other end is put a pressure safety valve.This column comb combining structure vacuumizes through Cleaning and Passivation and annotates working medium sealing and appearance and cover with paint, lacquer, colour wash, etc. processing and be this radiator finished product.During use isolated tube being linked to each other with the heating system pipe network can the efficient heat transfer heat radiation.
The column comb of this radiator can adopt two kinds of methods to make.First method is to stitch weldering with sheet metal after compression molding to make.Second method is with making after the metal pipe material cutting welding.The kind of sheet metal or tubing, specifications and models thickness design according to the compatibility and the economic technology condition of heat sink applications scope pressure vessel code and working medium.Generally to select for use the air-tightness that allows to be used in vacuum range to inhale the few metal vacuum structural material of discharge quantity well.Commonly used have mild steel, stainless steel, red copper, brass, aluminium and aluminium alloy and a composite.The column comb of metal sheet is advisable with every block of compacting 3～6 pillar-shaped pipes.Are pressed into column comb and top and the bottom level communicating pipe thereof and are convenient to the shape that assembly welding can bear high vacuum negative pressure and internal heat expansion normal pressure again.According to the size of required thermal power and area of dissipation, every group of radiator can be welded into by 4～20 column combs.The column comb of metal pipe material moulding is welded into 6～30 arms with every block of comb and is advisable, and every group of radiator is made up of 1～10 block of column comb.
The isolated tube of this radiator also has two kinds of methods to make.First kind of column comb with metal sheet is supporting, adopts one or two the straight garden of metal pipes to make.Second kind of column comb with the metal pipe material moulding is supporting, adopts every block of column comb that an isolated tube is set, and the isolated tube of one group of radiator is made up of the isolated tube serial or parallel connection of some column combs.The isolated tube length of this radiator is greater than the length of column comb.Isolated tube also can be the independently part of the section of condensing of heat pipe or another heat pipe.When isolated tube during as a heat pipe a part of, can weld or adopt connections such as diaphragm valve through encapsulation process, the loose joint of ring flange screw thread mutually with its adiabatic section, make this combination heat pipe become secondary connection phase transition of vacuum cooling system with radiator body.The material of isolated tube, according to corrosivity and the corrosion resistance of metal material and the compatibility design alternative of working medium of heating agent in the scope of application.The specifications and models of isolated tube design according to heating system maximum working pressure pressing force pipeline standard.The wall thickness of isolated tube generally is selected within 2mm～3.5mm.The internal diameter of isolated tube designs by the pipeline engineering standard according to the kind of heat flux and heating agent.
The isolated tube of this radiator is the transmission channel of thermal source, is again the isolating device of radiator and thermal source medium and pressure.In thermal source transmission pipeline and isolated tube, pressure can be several, the dozens of gauge pressure, and in the radiator of pressing the operation of phase transition of vacuum principle of isolated tube packing, because can select the different saturated vapor pressures and the working medium of filling weight seldom, pressure can be by design and operation several or one below the gauge pressure.Otherwise, also can design the scheme that the column comb group internal pressure of sening as an envoy to is greater than or equal to thermal source and transmission pipeline internal pressure.In the occasion that only needs temperature and heat, design based on the scheme of transmission with the heat of thermal source isothermal or the little temperature difference, but and the reduction of pressure several times, saving is used for the metal material consumption of pressure security aspect, and can further reduce thermal resistance.Needing pressure can be main occasion, can design the pressure that uprises based on transmission can scheme.It is constant and make heat supply and scheme with the isolation of hot two system medias to design the pressure and temperature heat.Seemingly as power transformer.Though its primary coil and secondary coil separate, directly be not communicated with, the primary and secondary coil that is arranged on the same iron core can be with voltage and current conversion expeditiously.This radiator has more easily solved the energy change of variable of heat temperature and pressure.
The porous layer of this radiator is the porous mass with alveolation and capillary imbibition characteristic on the isolated tube outer surface that is through in level communicating pipe.Porous layer can be the stacked of net, also can adopt method surfaces, garden outside isolated tube such as electrochemistry, sintering, machining and spraying directly to make.The effect of porous layer, the one, draw working medium for the isolated tube heat exchange, the 2nd, strengthen alveolation, improve the boiling heat transfer coefficient of working medium.
The row's of vacuumizing fixed gas dual-purpose valve of this radiator is integrally manufactured, can be needle-valve class, combination valve class.Specification requirement is that vapour lock is urinated and is convenient to annotate working medium in the preparation vacuum, and the instrument of being convenient to is by hand driven the pressure fixed gas.The leak rate of allowing under this valve standstill seal state is 1.33 * 10
-8Handkerchief liter/second.
The safety valve of this radiator declines with non-return and opens safety valve and be advisable.The leak rate of allowing under its standstill seal state is 1.33 * 10
-8Handkerchief liter/second.Its opening pressure is determined according to the radiator maximum working pressure.Exhaust capacity should be greater than the safety relief amount of radiator internal volume.If the maximum working pressure design is in 1 gauge pressure in the radiator, this valve can not established.Because can be by the best filling weight of working medium in the design control radiator.When the heat source temperature superelevation in the design maximum operating temperature after, the working medium evaporation capacity is greater than condensation number.When its liquid level is lower than porous layer lower edge deposited on the isolated tube, " drying up " phenomenon takes place promptly, relatively weaken and stop the phase transformation evaporation, steam inside is pressed and is also rested under the design maximum pressure.That is to say that pressure change-vacuum-phase change radiator will automatically be operated within the extreme design pressure.
Filling the working medium kind in this radiator can be good with column comb group and the used metal material compatibility of isolated tube, and the working medium quality factor is high, meets the various liquid or solid materials with thermal storage effect of design serviceability temperature scope.The operating temperature range that is used for the interior working medium of radiator of heating is advisable with 0～150 ℃.Working medium also can be certain phase-change material with thermal storage effect.Can be single working medium.It also can be compound or mixed working fluid.In fill working medium quantity according to the saturated vapor pressure of working medium, radiator body internal volume, use factor such as operating pressure to select.Working medium commonly used has pure water, alcohol, methyl alcohol, Fu Liang, acetone, Dowtherm, sulfide etc.
This radiator have removable transsexual and regeneration characteristics.If internal vacuum descends too much, when the spreader surface non-uniform temperature has obvious cold-zone, can adopt bleed regeneration or adopt the regeneration of thermal vacuum method row fixed gas of factory by the user.The specific implementation process of thermal vacuum method is: will need the isolated tube of the radiator of regenerating to add the heat (can use a lot of methods such as mixed-pressure boiler water, steam, Oil-burning blow torch or electric heater) of higher temperature.Deploying a temperature-measuring range on the radiator at the thermometer more than 120 ℃, after the spreader surface temperature rises to more than the normal maximum operating temperature, available hand tools is opened the row's of vacuumizing fixed gas dual-purpose valve venting, venting to the sound of giving vent to anger hour is closed dual-purpose valve, after temperature to be heated rose, it was promptly renewable to repeat twice of exhaust according to preceding method.
At present, differently there is the following deficiency in various radiators:
1. the big steel consumption of the heat radiation thicker thermal resistance of wall is many, and fouling and corrosion problem are serious, and the voltage endurance capability difference is leaked vapour and leaked more general.
2. existing heat pipe and vaccum phase conversion heat exchanger still can not generally be common in the various heat transfer cooling system heat supply networks.
3. the transmission range of cluster type heat pipe is subjected to certain limitation.Separate heat pipe is because big at a distance of tens of meters the big vapour lock of whole system internal volume, and general high vacuum acquisition equipment is difficult to the requirement of competent evacuation process.Manufactory can not once make, and can only use the thermal vacuum manufactured in the erecting bed.Therefore, fill the working medium amount and be difficult for accurately control, vacuum can only satisfy low requirement, and the thermal efficiency is affected.
Compared with the prior art the present invention has promptly adopted efficient heat transfer radiating principle such as phase transition of vacuum boiling alveolation, is provided with this special construction of isolated tube again dexterously.Changed the routine that heating agent is directly flowed through and is full of the radiator internal volume.Be spaced inside and outside the radiator, the radiator internal pressure can be manually designed be controlled at certain scope that is higher than heating system pressure of being less than or equal to.Can select to press in the radiator ratio with heating system pressure in people's wish as transformer, make it to be operated in optimum range.Be spaced inside and outside the radiator, the general entrained sincere of the abundant of rotten green onion of heating agent gets over fish hawk billy goat halter strap and closely questions difficult wholesale and sprinkle thoroughly and entangle Guang and chant loess hills Fu and appoint and wait upon ancient term for country school and stand up that to wander that suburb candy ∩ ⑷ herds around the Li of halter strap Venezuelan be that the ellipse Qi of declining Engel curve dental caries shelves is copied outspoken several waste time fine and soft reed Gou that lays down of southern mould that plants and sipped the surplus of sword and reflect な gown lemon unconventional Mian and post gown and emit and step on legendary venomous insect Pi, the Yihe River, Yun county and take off dog section С and kill only ┱ ridge to the purple of have eaten one's fill file bosom ditch＞Sui silk mountain
The present invention compared with the prior art, range of application is wider.Be convenient to long-distance transmissions with hot.Can adopt existing two-tube circulating vapour or water, the carbonated drink mixed transport also can be transmitted with the heat pipe-type single tube, even can dispel the heat with the normal air heat of compression transmission that waste heat air or heat pump provide.Because this radiator internal volume often is under the vacuum state, the boiling point of internal working medium and freezing point are than much lower under the normal atmosphere pressure condition, there is not the problem of freezing spalling heat radiation wall in very a spot of in addition working medium, and is therefore freeze proof respond well, is specially adapted to extremely frigid zones and intermitting heating system.
Compared with the prior art the present invention can make change-vacuum-phase change radiator be convenient to obtain equipment batch production manufacturing with high vacuum, can guarantee to fill the accuracy and the optimised quantity of working medium.Guarantee the acquisition of radiator internal volume high vacuum, guarantee high efficiency and safety in utilization.
