There is defect in the only steam heating pipe of technical scheme of prior art and communicating pipe entirety UNICOM heat conduction, its defect is carried out to technological improvement and increase the heating surface area of heat exchanger, invented branched thin heating installation pipe combination and formed circulating-heating fluid passage with header cavity UNICOM.Change traditional thought and think that steam heating pipe must be the wrong views that pipe that diameter is thicker could be realized Fluid Circulation.Applicant is decomposed into 6 thinner arm heat conduction diameter 12mm by a traditional only thicker steam heating pipe and is arranged in each cold water pipe official jargon, form header inner chamber UNICOM, the zone of heat liberation resistance of shunting circulation is little, branched thin steam heating pipe impels hot fluid center heat to discharge fast, the described horizontal increase of branched thin heating installation pipe combination hot fluid metal surface contacts with cold fluid, the multitube passage heat conduction of branched thin heating installation pipe composition, the technical scheme of cold water tube chamber internal ratio prior art increases by 45% one 100% heat transfer areas, make full use of the limited heat of the low coolant-temperature gage of current heating and accelerate rate of heat transfer, improve heat exchange efficiency, realize and flow out continuously the continual technique effect of hot water.
The utility model adopts the smooth generation incrustation scale of stainless pipe inside and outside wall to be difficult for absorption, extends incrustation scale adsorption time, stainless steel tube reducing pipe UNICOM compression resistance is strong, corrosion-resistant, it is durable to prolong life, heating installation circular tube external wall produces incrustation scale and is easy to acid filling and cleans, pour out and outwell, it is clear that exchange hot water is pollution-free, pure, is that domestic water can also be had a bath.The stainless pipe heat conduction of thin-walled is fast, larger than the tubing cavity volume of same outer diameter, stored hot water is many.Use package cavity stores when heat exchanger hot water can extend cold water that the very first time enters cold water pipe tube chamber from heating outlet end and be detained that to add heat exchanger time long, long flow path, at this moment the cold water entering contacts again exchange heat absorption with branched thin steam heating pipe metal covering fast, it is high that the heat of hot fluid can all discharge the thermal efficiency, in steam heating pipe port of export cold water tube chamber, set up the heat transfer area that branched heating installation tubule strengthens the exchange of the cold water very first time, the hot water that has solved water storage type heat exchanger internal memory flows out from the cold water heat exchange titting water outlet of heater inlet pipe joint 10 ends settings, the cool water heating exchange process newly entering with the cold water inlet joint of heating installation titting water outlet 9 end settings is not connected this technical problem.
3, as shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5 Figure 18, Figure 19, Figure 21, the cross sectional shape of described header body is D word shape; Between described branched cold water pipe 2 and adjacent cold water pipe 2, be communicated with pipe 7 by cold water and weld UNICOM, be provided with two above thin heating installation pipes 1 in every cold water pipe 2 chambeies, thin heating installation pipe 1 quantity arranging in every cold water pipe 2 chambeies is identical or different; Hot fluid in thin heating installation pipe 1 communicates with header inner chamber 12 and forms circulating heat transfer fluid passage.
4, as shown in Fig. 3, Fig. 4, Fig. 5, the quantity of the described heating installation pipe 1 arranging in described every cold water pipe 2 chambeies increases progressively or several times increase by propping up to heating installation titting water outlet 9 ends successively from heater inlet pipe joint 10 ends, forms multitube heat conduction circulation of fluid passage near hot fluid and header inner chamber 12 in the intraluminal heating installation pipe 1 of heating installation titting water outlet 9 end cold water circle.
At present heating circulating hot water temperature is low, and steam heating pipe of technical scheme heating installation exchange water heater of prior art flows out at the slow hot water storing of the little exchange rate of cold water pipe tube chamber coiling heat transfer area cold water heat exchange that the heat taken away newly enters and do not catch up with and occur that hot water is not connected defects such as interrupting 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 heat exchange with the steam heating pipe of heating outlet end, at this moment middle part cold water tube chamber and the intraluminal cold fluid of heating installation entrance point cold water and heating installation fluid or heat exchange does not occur equal temperature, using cold water that the prolongation of flowing out the hot water time when heat exchanger newly enters to promote flow of hot water does not catch up with to flow through and flows out hot water to heating installation entrance point cold water heat exchange titting water outlet exit and interrupt cooling off through exchanging to the rate of heat exchange of middle part cold fluid.
Central heating at present, point family independent pipe network design heating charge management.The technical problem that the utility model interrupts in order to solve the discontinuous outflow hot water of heat exchanger, heating exchanger takes branched cold water pipe and orifice plate inside header 4 to be welded to connect into entirety, forms cold fluid independent parallel circulation heat absorption fluid passage.The one: connect branched cold water pipe increase moisture storage capacity and extend swap time.The 2nd: in branched cold water pipe tube chamber, can hold branched thin steam heating pipe increases heat exchange area and exchange long flow path.The 3rd: the cold water that newly enters heat exchanger in order to reduce reduces effect with mixing of interior stored hot water, it is independent parallel circulating heat transfer passage that the utility model arranges cold fluid, and the exchange operation length that increases cold fluid improves heat exchange efficiency and solves the unbroken technical problem of outflow hot water.In the most of adjacent cold water pipe of exchanger heat fluid outlet chamber, branched thinner heating installation pipe being set is diameter 12mm, thin heating installation pipe forms the tower design of step, the branched steam heating pipe metal covering that its object very first time enters in cold water and first cold water pipe of heating installation titting water outlet 9 end of heat exchanger starts exchange heat absorption, the hot water that branched cold water tube chamber stores extends the cold water newly entering and flows through second first cold water pipe tube chamber exchange through cross over pipe, the 3rd by that analogy swap time long, the flow process heat time is long, cold fluid reaches abundant exchange heat absorption flow process to heater inlet pipe joint 10 pipeline section cold fluid outlet temperatures and hot fluid tube wall temperature basic identical stop with branched steam heating pipe at exchange area long flow path in tube chamber delay and exchanges.Therefore, the heat exchange area that technical solutions of the utility model improve unit volume heat exchanger increases by 45% one 100%, and this design of heat exchanger compact conformation, economical rationality realize output hot water amount and continuously outflow greatly continuously the technique effect of hot water.
In the utility model, in hot fluid port of export cold water tube chamber, arrange or increase branched thinner heating installation pipe by propping up to increase, accelerating rate of heat transfer, improving heat transfer effect.Also can design flexibly according to product specification the number of heating installation pipe, the little product of specification all arranges 6 tiny heating installation pipes of diameter 12mm in each cold water pipe chamber, can realizing small dimension product, also to flow out hot water uninterrupted, the product that specification is larger, tiny steam heating pipe circle is set branched 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, ensure again heat transfer effect.
In the utility model, described branched thin heating installation pipe heat conduction has not only increased the heat exchange area of heat exchanger, and branched heating installation pipe is set in each cold water pipe chamber, import department and the exit of the branched thin heating installation pipe of header inner chamber 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 heat that the hot water that heat exchanger flows out is drained and the cold water that simultaneously enters heat exchanger absorb branched thin heating installation pipe liberated heat and are 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 heating installation pipe makes up prior art is set in heat exchanger heating outlet pipeline section cold water pipe and causes the disappearance of the required area of cold water and temperature because of the reduction of heat supply temperature.In the utility model cold water pipe chamber reasonably the number of the increase heating installation pipe tubule of science cold fluid obtain the heat output of maximum possible, thereby the heat that makes hot fluid center can obtain rationally discharging and utilizing, effectively prevent that heat exchanger from flowing out the interruption of hot water, set up tiny heating installation pipe branched pipe heat conduction liberated heat, effectively solve the little stored hot water of heat exchanger heat transfer area and flow out the cold water covering and exchange the technical problem not catching up with.Solving an only steam heating pipe fluid center heat cold fluid obtains abundant heat-shift and effectively utilizes low technical problem.
