6, as shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5,6, Fig. 7, Fig. 8, Fig. 9, Figure 10, Figure 11, Figure 12, Figure 17, Figure 18, Figure 20, Figure 21, described branched cold water pipe 1, cold water pipe 1 limit is managed a location, arc surface tube wall side, termination and is suppressed with plane platform 12; Manage an adjacent cold water pipe 1 one location, arc surface tube wall side, termination with its limit and be suppressed with plane platform 12, another location, arc surface tube wall another side, termination is suppressed with plane platform 12; In the plane of plane platform 12, have successively cold water pipe connector 13; The tube wall of described cold water pipe connector 13 is to outer wall or to the straight wall pipe of inner chamber drawing turned welt flat mouth 14; Direct-cooled water connection pipe 2 inserts successively cold water pipe 1 and welds in turn serial connection UNICOM to outer wall or the straight wall circle of inner chamber drawing turned welt flat mouth 14; The corresponding end that is communicated with pipe 2 UNICOMs between adjacent cold water pipe 1 and adjacent cold water pipe 1 with direct-cooled water is provided with support member 11, the cold water pipe 1 that support member is adjacent; Or branched cold water pipe 1 location, two ends arc surface tube wall two sides is all suppressed with plane platform 12 has cold water pipe connector 13 in plane platform plane; Between described branched cold water pipe 1 and adjacent cold water pipe 1 tube chamber two ends tube wall all by direct-cooled water be communicated with pipe 2 successively through cold water pipe 1 to welding UNICOM each other mutually in turn in outer wall or the straight wall of inner chamber drawing turned welt circle flat mouth 14, between branched cold water pipe, support member 11 is not installed; Direct-cooled water is communicated with pipe 2 and welds UNICOM through cold water pipe connector 13 tube walls to straight wall pipe flat mouth 14 inherent cold water pipe 1 outside or the inner chamber of outer wall or inside drawing turned welt; In every described cold water pipe 1 tube chamber, pass and have only Zhi Nuanqi pipe 3 or combination heating installation pipe 17; Described heating installation is communicated with pipe 4 and is communicated with pipe 2 tube chambers through direct-cooled water, insert in the steam heating pipe connector 23 or the straight wall flat mouth 22 of steam heating pipe on connection pipe 25 tube walls in the straight wall flat mouth 22 of steam heating pipe connector 23 on only Zhi Nuanqi pipe 3 tube walls or steam heating pipe or on combination heating installation pipe 17, in heating installation pipe 3 mouths of pipe or connect in pipe 25 mouths of pipe and weld UNICOM; Described steam heating pipe closure plate 6 and heating installation pipe 3 or the limit that connects pipe 25 mouths of pipe merge, and in cold water pipe 1 mouth of pipe, are welded to connect; Described end socket closure plate 5 boss arc end sockets or concave shaped end socket have limit to be embedded in cold water pipe 1 mouth of pipe to weld and be connected to turning up; Described heating installation inlet connector tube 7, heating outlet pipe joint 8 connects pipe 25 top and end welding UNICOM with heating installation pipe 3 and/or combination heating installation pipe 17, be welded to connect with the 1 limit pipe import of cold water pipe and the outside end socket closure plate 5 of outlet again, form hot fluid circulation heat transfer fluid passages; Described cooling water inlet pipe joint 9 and cooling water outlet pipe joint 10 and cold water pipe 1 tube wall bottom, limit, both sides, top welding UNICOM, form Fluid Circulation heat recipient fluid passage.
Heating low-temperature heat source at present, steam heating pipe of technical scheme heating installation exchange water heater of prior art is little at cold water pipe tube chamber coiling heat transfer area, and the slow hot water storing of exchange rate flows out cold water heat exchange that the heat taken away newly enters and do not catch up with and occur that hot water flows out defects such as not being connected interruption weak effect.The cold fluid of water storage type heat exchanger cold water pipe tube chamber under static state and the hot fluid of steam heating pipe tube chamber are equal temperatures, in the time using interchanger to flow out hot water, the cold water that synchronously enters heat exchanger starts to carry out very first time heat exchange with the steam heating pipe of hot fluid heating outlet end, at this moment there is not heat exchange in fluid or the equal temperature of middle part cold water tube chamber and the intraluminal cold fluid of heating installation entrance point cold water and heating installation tube chamber, using heat exchanger to flow out internal memory hot water flow to hot fluid heating installation entrance point cold water heat exchange titting water outlet exit and flows out hot water and interrupt cooling off weak effect through exchanging to middle part because the long cold water newly entering of delivery time promotes flow of hot water because the rate of heat exchange of the low fluid of the little temperature of heat transfer area does not catch up with.
Central heating toll administration at present, point family independent pipe network design low-temperature heat source heating.The present invention flows out in order to solve heat exchanger the technical problem that hot water interrupts, and heating exchanger is taked branched cold water pipe welding UNICOM to form overall sheet and formed straight tube parallel fluid circulation heat absorption passage.The one: rational science connects branched cold water pipe increase moisture storage capacity can extend swap time, and it is long that the cold water delay entering from hot fluid port of export cold water pipe portion adds heat exchange process.The 2nd: the combination steam heating pipe of the interior branched narrow tube composition arranging of the branched cold water pipe of part tube chamber that hot fluid heating outlet pipe joint 8 ends are adjacent increases heat transfer area, and the amount of turbulence of enhance fluid change fluidized bed, and reinforcement is conducted heat.The 3rd: in order to prevent that the cold water that newly enters heat exchanger from reducing effect with mixing of interior stored hot water, cold fluid of the present invention is communicated with pipe by butt welding wall connecting leg 24 or direct-cooled water and forms straight tube PARALLEL FLOW heat transfer path.The delay exchange and the operation length raising that increase cold fluid are efficient, solve water storage type heat exchanger and flow out the unbroken technical problem of hot water.The present invention compared with prior art have expection less than technique effect.
It is the branched tubule composition of minor diameter 12mm that the present invention arranges combination heating installation pipe in the most of adjacent cold water pipe of exchanger heat fluid outlet chamber, thin heating installation pipe forms the tower design stepped heating of step, and its object very first time enters the branched steam heating pipe metal covering of combination heating installation pipe in cold water and first cold water pipe of heating outlet pipe joint 8 end of heat exchanger and starts exchange and absorb heat.The hot water that branched cold water pipe chamber stores extends the cold water that newly enters flow through second, the 3rd by cross over pipe first cold water pipe tube chamber exchange grow swap time by that analogy, the long flow path heat time is long, cold fluid is detained and adds heat exchange area long flow path at tube chamber, to reach abundant exchange heat absorption flow process to hot fluid heating installation inlet connector tube 7 pipeline sections, basic identical stopping exchanges for cold fluid outlet temperature and hot fluid tube wall temperature.Therefore, the heat exchange area that technical solution of the present invention reasonably improves heat exchanger unit volume increases by 55%～100% heat transfer area, and being arranged in each cold water pipe tube chamber of science.This project organization compactness, science, economical rationality, realize output hot water amount and flow out greatly, continuously the unbroken technique effect of hot water.
In the present invention, in hot fluid port of export cold water tube chamber, increase by propping up the combination heating installation pipe 17 that arranges or increase branched thinner diameter heating installation pipe composition, accelerate rate of heat transfer, improve heat transfer effect.Also can design flexibly according to product specification the number of heating installation pipe, in each cold water pipe chamber of the little product of specification, all arrange 6 or prop up above minor diameter 12mm combination heating installation pipe, can realizing small dimension product, also to flow out hot water uninterrupted, the product that specification is larger, 4 minor diameter 12mm combination heating installation pipes of tiny steam heating pipe circle are set in the most of adjacent cold water pipe of hot fluid port of export chamber, it is that output channel is used that an only heating installation pipe is set in cold water pipe chamber corresponding to hot fluid entrance point, so, save material, guarantee again heat transfer effect.
In the present invention, described branched thin heating installation pipe heat conduction has not only increased the heat exchange area of heat exchanger, combine heating installation pipe and arrange in each cold water pipe chamber, import department and the exit of combination heating installation pipe form repeatedly amount of turbulence, effectively change the fluidized bed of fluid, accelerate rate of heat transfer, cold fluid coolant-temperature gage increases in gradient, impel the cold water that is introduced into heat exchanger tube chamber to contact at the many partitions of the first exchange area and hot fluid the abundant exchange heat absorption of looking swap time, the hot water heat of draining and the cold water that simultaneously enters heat exchanger that heat exchanger flows out absorbs combination heating installation pipe liberated heat and is directly proportional in retaining state or the process of flowing through, cause the temperature that the very first time enters heat exchanger cold fluid to improve constantly along metal heat transfer face, the temperature of hot fluid declines along metal heat transfer face is disconnected, cold fluid flow absorbs heat and is circulated to the basic identical heat transfer of hot fluid heating installation import thermal balance pipeline section fluid temperature (F.T.) and stops in process.Therefore, the only steam heating pipe of technical scheme that the heat conduction of tiny combination heating installation pipe makes up prior art is set in exchanger heat fluid heating outlet pipeline section cold water pipe and causes the disappearance weak effect of the required area of cold water and temperature because of the reduction of heat supply temperature.The arranging of cold water pipe of the present invention chamber clinical practice increase the number combination of tubule heating installation pipe cold fluid obtain the heat output of maximum possible, thereby the heat that makes hot fluid center obtains rationally discharging and utilizing, effectively prevent that heat exchanger from flowing out the interruption of hot water, set up the combination heating installation pipe branched pipe heat conduction liberated heat being formed by minor diameter steam heating pipe, effectively solve heat exchanger heat transfer area little, stored hot water flows out the cold water covering and exchanges the technical problem not catching up with.Solving an only steam heating pipe arranges unreasonable fluid central heat source and can not get the technical problems such as effectively utilization.Therefore, technique scheme of the present invention reaches fully effectively utilizes heat, saves the material energy, its intensity is enough, heat transfer property reliable, reasonable in economy, compact conformation, guarantees to meet needed hot water flow in the process of having a bath.Comprehensively above-mentioned, this technical scheme has effectively solved the deficiency of the technical scheme heat exchange area of prior art, a steam heating pipe arranges the technical problems such as layout is unreasonable, the effective utilization rate of thermal source is low at cold water pipe tube chamber.The present invention more adapts to dependability requirement, and the thermal efficiency is high, flow out the unbroken technique effect of hot water.
7,, as shown in Fig. 5, Fig. 9, Figure 10, Figure 17, Figure 18, Figure 20, cold water pipe 1 tube wall arc-shaped surface local positioning is suppressed with plane platform 12; Plane platform 12 plane upper punches are pressed with cold water pipe connector 13, and cold water pipe connector 13 tube walls are to outer wall drawing turned welt Cheng Zhibi pipe flat mouth 14; It is cylindrical flat mouth that described direct-cooled water is communicated with pipe 2 mouths of pipe, direct-cooled water is communicated with the pipe 2 two ends mouths of pipe and inserts cold water pipe 1 in the straight wall pipe flat mouth 14 of outside drawing turned welt, respectively direct-cooled water is communicated with to pipe 2 welds UNICOM in cold water pipe 1 straight wall pipe flat mouth 14 outsides; Or described cold water pipe 1 tube wall arc-shaped surface local positioning is suppressed with plane platform 12; Plane platform 12 plane upper punches are pressed with cold water pipe connector 13, and connector tube wall is to inner chamber drawing turned welt Cheng Zhibi pipe flat mouth 14; It is cylinder flat mouth that described direct-cooled water is communicated with pipe 2 mouths of pipe, and direct-cooled water is communicated with the pipe 2 two ends mouths of pipe and inserts in the straight wall pipe flat mouth 14 on cold water pipe 1, in cold water pipe 1 tube chamber inner plane girth welding welding UNICOM (as shown in Figure 17, Figure 18, Figure 20).
Realizing cold water pipe supervisor is communicated with pipe and welds UNICOM at outside reducing pipe with the direct-cooled water of arm; Must be suppressed with plane platform in stainless-steel pipe cold water pipe arc surface tube wall local positioning, plane platform is interior concave plane platform or evagination plane platform, circle flat mouth at the mouth of plane platform plane upper punch, in flat mouth, drawing turned welt is that straight wall pipe flat mouth edge is neat, after the cutting of direct-cooled water connection pipe arm, must not reprocess is the cylindrical flat mouth of straight tube, arm inserts the outside weldings of the inherent cold water pipe of the straight wall pipe flat mouth of supervisor, take inwall applying argon gas protection weldering outside weldings communicating pipe, the advantage of gas shielded arc welding is: electric arc good linearity, easily realizes all-position welding; In arc heat quantity set, molten bath is little, and speed of welding is fast, and heat affected area is narrower, and weldment distortion is little, and anti-crack ability is strong, and weldquality is good.Operation is easier to, stability is easy to control well grasp, intercrystalline corrosion be can prevent or slow down, weld strength and weldquality improved, its welding even weld is closely knit, have advantages of firmly durable, strength of joint is high, tightness good, cost is low, use after not often maintenance management.And process time, the saving energy, the reduction amount of labour used of saving parts, raise labour efficiency, reduce production costs.It is that oval mouth is saddle port to arc in-flanges that relative and prior art scheme is blurted out on supervisor's arc surface tube wall, in tube chamber, on saddle port, the bonding crack of welding saddle port is not easy to grasp bad control with rising and the decline stability of circular arc, and low being easy to of weld seam poor welding quality intensity leaked.
Realize cold water pipe supervisor and be communicated with the inner reduced pipe plane-welding of pipe UNICOM with the direct-cooled water of arm; Must be suppressed with plane platform in cold water pipe arc surface tube wall local positioning; The location punching press of plane platform has cold water pipe connector, and connector tube wall is to inner chamber drawing turned welt Cheng Zhibi pipe flat mouth; It is cylindrical flat mouth that direct-cooled water is communicated with the pipe mouth of pipe, and direct-cooled water is communicated with pipe and inserts in the straight wall pipe of cold water pipe flat mouth; In cold water pipe tube chamber inner plane girth welding welding UNICOM; It is concordant that two weldment interfaces are sewn on a plane upper edge hole limit, adopts the little electric current face bonding of argon arc welding stability to be easy to grasp, the reliable antileaking of welding quality stable in cold water pipe 1 mouth of pipe.Take in tube chamber welding to hide weld seam, outside without welding bead vestige, outward appearance is without manual polishing polishing section saving working hour, material, and attractive in appearance being conducive to of product design sells.
