Beneficial effect of the present invention:
1, the present invention is the two cavity header body of a kind of novel circular tube shape or square tubular shape; In porous, plate is divided into interior half hot fluid cavity passage, outer half cold fluid water storage diffluence room cavity passage header.Pipe, sheet material are same metal " 304 " material design of material, cold water pipe arranges single, two or branched pipe opened type welding cavities and is communicated with, and in single file, duplicate rows or the many partitions of multirow passage and porous, plate synchronously absorbs the interior storage ability of swimming high-performance heat exchanger of heat.According to size and the heating surface area size of the number of the temperature of heat supply district heating and heating tube pipe, length, bore, select number, length dimension, the caliber size of cold water pipe pipe flexibly.Take full advantage of for heat energy expansion endotherm area and interior heat accumulation ability of swimming and, increase the heat transfer area that ladder heat transfer reasonably adds unit volume, abundant for the heat of hot fluid many partitions are absorbed conversion, reaches and reasonably increase heat-transfer surface area, improve the object of heat transfer effect.Both saved material to be also convenient to clean the technique effect that incrustation reduces manufacture and recruitment cost.
2, the advantage of cold water pipe pipe opened type cavity connects: the welding of cold water pipe straight length opened type is communicated with, without communicating pipe connection, straight length two-port cavity connects between cold water pipe tube and tube, bigbore pipe dirt not easily adsorbs blocking.Assuming that arrange certain cold water pipe of branched tubule to occur dirt deposits blocking etc. in different switching phase, do not affect other pipe and exchange absorption heat yet, the unchanged effect of cooling water outlet flow is without impact, and dirt not easily adsorbs blocking, even if produce incrustation scale blocking to be easy to manual cleaning.During cleaning, open half header plate outside one end and just can dredge cleaning, also manually can clean by acid filling liquid, pour into acid solution from header top delivery port, chemical reaction half header cavity outside the water storage diffluence room of two ends of generation occurs, and dirt is discharged through cold water pipe outlet simultaneously.Solve the inlet-outlet connector that prior art two ends is cold water pipe, single tube length at heating tube cavity inside enclosed reciprocating disk around once produce very small sediment incrustation, just be easy to block full tunnel, not water outlet or cold water water flow is very little cannot use, generate incrustation scale and can not pour into acid solution, cannot the technological deficiency of cleaning and dredging.The great advantage of cold water pipe opened type cavity UNICOM is, can press number, the caliber size of the mouth of pipe footpath size Selection cold water pipe of product specification or volume size and heating tube list arm flexibly.Not only save material but also reach the object design of heat transfer effect.
3, design feature of the present invention: header cavity is divided into interior half hot fluid cavity, outer half is cold fluid cavity water storage, and in porous, plate is divided into duplicate rows passage and is communicated with without the need to communicating pipe, and heating tube pipe and cold water pipe pipe two ends opened type cavity connects circulate; Cold water pipe is arranged according to flexibilities such as product casing specification size, single heating tube mouth of pipe caliber size, heating surface area size, water quality alkalinity, water hardness situations, arranges one, more than two or two cold water pipes as required.One, two cold water pipes are adapted to big-and-middle specification product and water quality alkalinity is large, water hardness is higher area is arranged, and reduce incrustation blocking cold water pipes, one, two is medium-large caliber pipe water storage heat absorption type.More than two cold water pipes are adapted to small dimension product, small-bore pipe water storage fast endothermic formula, but the higher regional small dimension product of the large water hardness of water quality alkalinity is also adapted to the setting of more than two heavy caliber cold water pipes, reduce incrustation blocking pipe.Saved material, be convenient to cleaning incrustation reach heat transfer effect again.Cold and hot two kinds of fluid opened types exchange the heat absorption of many partitions and inner storing water formula, reduce flow resistance, the heat transfer condition of cold and hot two kinds of fluids flowing space ambassador heat-transfer area both sides in heat exchanger is close, reduces the defects such as the round flow velocity erosion corrosion welding bead often of fluid turnover.In cold fluid water storage diffluence room and cold water pipe, stored hot water plays and enables large the supplementing of heat exchanger hourly water consumption, and the amount storing water makes up the slow defect of hot fluid temperature rate of circulating flow on the low side.The water-holding quantity of water storage diffluence room and the savings of cold water pipe is increasing cold fluid operation length in varying degrees, extends the time of heat exchange, and the hot water of savings internal memory adds heat transfer effect.In many partitions areola endothermic tube and hot fluid PARALLEL FLOW process, heat is all absorbed without staying dead angle, its technique effect reaches the heat output of maximum possible.
4, the present invention arranges cold water pipe one, the advantage of two by the specification size of product: the large long flow path of large-scale specification product (specification product of more than 1m) heating surface area arranges branched cold water pipe waste material, a cold water pipe is set in heating tube cavity and adopts external diameter 25 ~ 38mm bore pipe, not only heat-absorbing water-storage formula exchanges, and saves material but also can reach best heat transfer effect.Medium-sized specification product (specification product of below 1m is containing 1m) arranges two cold water pipes in heating tube cavity, adopt external diameter 18 ~ 22mm bore pipe, manage the stored hot water in half header cavity outside interior stored hot water and water storage diffluence room, play and enable large the supplementing of heat exchanger hourly water consumption, the amount storing water makes up the slow defect of hot fluid temperature rate of circulating flow on the low side, it is long that the cold water that during output hot water, heat exchanger lower end covers stops the heat time in cold water pipe cavity, in cold fluid and hot fluid PARALLEL FLOW process, heat is all absorbed without staying dead angle to exchange, its technique effect reaches the heat output of maximum possible.Prior art fixedly touch formula one-pipe closed communication reciprocating disk around, cannot by the technological deficiency that product specification size selects the number of cold water pipe, caliber size calculate required heating surface area.Small dimension product heat exchange efficiency is low cannot be used, and it is also very poor that big-and-middle specification product wastes material result.
5, the present invention arranges the branched advantage of cold water pipe by the specification size of product: small-sized specification product (specification product of below 80cm is containing 80cm) the little flow process of heating surface area is short, must branched small-bore cold water pipe be set in heating tube cavity, increase heating surface area, branched cold water pipe is set and is covered with heating tube cavity many partitions intussusception heat Fast Heating, form the MTD that cold fluid multichannel adverse current can be larger, the thinner hot fluid of cold water pipe caliber flows through the water-holding quantity that heat conduction penetrates the many partition heat absorption of cold flow layer and water storage diffluence room, cold fluid obtain fully conversion by absorption heat to etc. boundary's point, improve the heat exchange efficiency of small-sized specification product, namely the technique effect of material is saved.
6, the technology of the present invention structure brings new technique effect: low temperature heating can be changed hot water taking and continuously export, solve heating water temperature lower than under 45 ° of water temperature condition, heating installation transition heat hydrophone can reach cold fluid delivery outlet coolant-temperature gage and the synthermal technique effect of hot fluid inlet water temperature degree, exports hot water and successively flows the Best Practical that can meet user and have a bath.Based on current low temperature heating heat transfer conditions, prior art " hot Bao Leng " heat exchanger with collected boxes, the output in 1 ~ 3 minute of the hot water of cold water pipe tubule internal memory is cooled off to exchange again exports hot water use (because cold fluid flow speed fast cold water pipe absorption heat is few).Cold water pipe opened type UNICOM of the present invention can need to arrange cold water pipe by product specification size, formed in heating tube arrange cold water pipe one, two for stored hot water in the heat absorption of heavy caliber passage and with or the many partitions of small-bore branched passage absorb that heat is fast, two ends opened type welding cavity connectivity structure designs, in outer half header reservoir chamber, porous, plate absorbs heat and Upwards channel heat transfer, strengthens heat absorption and improves heat output.Expansion heat transfer area increases ladder heat transfer, two kinds of parallel reverse flows of fluid, mean temperature difference can be made to improve and transmit more heat, larger increase heat absorption radius, reduce heat loss, its object, to absorb completely from each position of low-temperature space exchange without dead angle often propping up heat that heating tube flows through.It is inwhole that preheating one-phase absorbs heat, water storage diffluence room internal memory hot water to hoist conversion heat from lower, the flow regime of cold water pipe passage alter is entered from outer half header cavity, improve turbulence pulsation degree, realize absorbing heat fast in second stage, temperature of going round and beginning again increases boundary's points such as reaching in gradient.Realizing exchanging the equal two kinds of relatively independent fluid PARALLEL FLOW directions of radius of curvature contrary, increase mean temperature difference, is most Wang heat transfer coefficient, the most desirable heat exchanger effectiveness, preferably heat transfer effect.
By changing heat-transfer surface shape and size, in order to increase convection transfer rate, cold water pipe also can adopt special pipe as elliptical tube, helix tube, bellows etc.

Can avoid producing electrochemical corrosion in use procedure with metal material to leak, the electrode potential of the metal of unlike material is different and form the galvanic corrosion that galvanic couple battery produces, and affects the defects such as life of product.
Header duplicate rows passage; The small-bore branched passage heat absorption of cold water pipe or the welding of single heavy caliber passage many partition heat absorptions two ends mouth of pipe opened type are communicated with (for manifold).Straight tube and screw thread emboss pipe, bellows etc. can be adopted to further increase the tt surface area of heat transfer by changing heat-transfer area structure cold water pipe, heat transfer area is increased in unit volume, two kinds of fluid PARALLEL FLOW directions are contrary, under the condition that the import and export temperature of fluid is identical, the mean temperature difference of adverse current is maximum.It is that cold water imports and exports one-pipe coiled coil or " Z " or serpentine coiling in traditional two ends, single Zhi Guanbi absorbs on the basis of heat, application augmentation of heat transfer, the present invention is under given state of temperature, make the heat of fluid by abundant Appropriate application to absorbing all kinds of heat exchanger of tradition completely, the important technical reform carried out.
Mainly contain following some:
One is that heat supply housing pipe and cold water pipe pipe adopt manual argon arc welding to pinch the equidirectional welding of limit two wall, the optional stainless steel pipe compared with thin-walled, sheet material manufacture, reduces metal consumption, reduces costs, and it is water-tight to pinch limit welding quality stable.Heating tube is chosen as Φ 50 ~ 76mm pipe or rectangular shaped tube etc., general wall thickness is 0.7 ~ 0.91mm, cold water pipe pipe adopts small-bore stainless steel tubule, rule of thumb data roughly calculate required endotherm area to economize on resources, and the economy objectives design that heat transfer effect accomplishes to make the best use of everything can be reached, by size of product or the difference of volume size or the height situation of user area heating water temperature, and the pipe number of heating tube, length and mouth are through size, pipe number and caliber size that cold water pipe is set can be increased and decreased flexibly.In the ordinary course of things, in a heating tube pipe in various degree cold water pipe pipe 2 ~ 5 arm bore is set at 9.5 ~ 16mm, large gauge product arranges 2 ~ 3 cold water pipe pipes in a heating tube pipe, small dimension product arranges 4 ~ 5 cold water pipe pipes in a heating tube pipe, and it is heavy caliber 25 ~ 38mm that maximum specification product arranges single cold water pipe pipe in a heating tube pipe.

Three are through repeatedly repetition test, facts have proved, prior art cold water endothermic tube pipe and the same length of cold water pipe pipe of the present invention, same to bore, stack pile, synthermal, pressure definite value, heating tube housing same specification, one-pipe length coiling one-pipe absorb heat, absorbing heat opened type with the many partitions of the branched pipe of the present invention is communicated with compared with inner storing water, exchanges heat outputting coolant-temperature gage difference but very large.Compared with the prior art the present invention improves the heat transfer effect of three times, and cooling water outlet coolant-temperature gage and heat supply heating installation inlet water temperature degree reach boundary's point such as synthermal, successive heat outputting washing bath.Solve existing heat exchanger technology and export hot water 1 ~ 3 minutes with regard to the non-serviceable defect that progressively cools off.
The present invention meets and to be combined with sheet material to adopt the equidirectional limit face bonding of pinching of flange from fusing welding procedure structure at the adapt pipe that is not subject to destruction of temperature and pressure condition, and the connecting mode of tube sheet and pipe is more suitable for dependability requirement.Thin-wall stainless steel tube sheet piercing and flanging pinch side weld connect reduce argon arc welding welding difficulty save solder, welding bead is attractive in appearance, and weld seam be can't see in partial appearance junction.Pipe and connecting plate embed and coincide that neat direction, bead limit is consistent pinches limit argon arc welding, the high-strength products life-span that improve welded seam is long, pinch side weld to connect the intensity adding weld seam and not easily crack or rupture, within the allowed band of thermal expansion force generation temperature difference pressure, thermal stress and compression, double-walled tube sheet coincide and pinches side weld and connect and reduce thermal stress at welding point place and may cause stress corrosion and break, and solves the technical barrier of intercrystalline corrosion welded seam fatigue life.Realize the new technology that each parts of tube sheet connect welding obstacle and dysopia welding operation, the present invention is welded to connect parts and is less than prior art, decrease welding procedure, the simple cost of manufacturing process is low, production and processing steady quality is reliable, and finishing convenience, economical rationality, reliable, reduction labour intensity and recruitment cost, saved human resources, save welding wire energy and material, enhance productivity or product quality, product practical periodically long-life long.
Compact conformation of the present invention, each attaching parts are same metal material material, and decreasing complicated technology and the recruitment waste of the manufacture of various metals material, is most economical one optimal design.Metal consumption is few, cost is low, heat transfer area increases, plate heat absorption circulation in header duplicate rows passage porous, cold water pipe opened type is communicated with the synchronous many partitions of branched cold water pipe and absorbs the hot water Upwards channel transmission prolongation heat exchanger time stored in heat, change the flow regime of cold fluid, improve turbulence pulsation degree and increase ladder heat transfer, cold water output water temperature degree successive flow identical with heat supply inlet water temperature degree improves heat exchange efficiency, effective, meet user's requirement, installed vertical is laterally convenient, flexible, lightweight convenient transportation, and save logistics transportation cost, it is the product that a kind of high-performance heat exchanger of novel energy-conserving practicality can replace prior art.The present invention has Substantial technical difference, compared with the prior art has outstanding substantive distinguishing features and marked improvement is apparent, has novelty creativeness.
