2, in every cold water pipe 2 tube chambers that described heating installation titting water outlet 9 ends are adjacent, the quantity of heating installation pipe 1 is more than the quantity of heating installation pipe 1 in cold water pipe 2 tube chambers of heater inlet pipe joint 10 ends; In cold water pipe 2 tube chambers of heating installation titting water outlet 9 ends, strengthen heat transfer area, minor diameter tubule strengthens heat transfer, and low-temperature heat source is utilized effectively.

In the utility model, header inner chamber is hot fluid circulation passage, household heating is by the closed cycle of mechanical water pump supply flow body, the pressure that header body bears is the mechanical pressure that water circulating pump is supplied with, it is constant pressure, before heat exchanger dispatches from the factory, adopt with the pressure of 1.25 times of the constant pressure multiplying factors of water circulating pump it is detected, can dispatch from the factory after qualified.Facts have proved, header zone of heat liberation has solved the technical problem that header body weld seam does not leak because of thermal expansion shrinkage stress deformation, and steady quality is reliable.

It is pipe that the utility model is selected branched cold water pipe, cold water communicating pipe is pipe, the branched minor diameter steam heating pipe arranging in cold water pipe chamber is pipe, and described branched thin heating installation pipe is connected closure plate 6 and is welded to connect with steam heating pipe, and header inner chamber forms circulating heat transfer fluid passage antileaking.Selecting thin-wall stainless steel is that orifice plate is welded to connect and reduces the complexity of manufacturing processing welding inside cold water pipe and thin-wall stainless steel steel plate header; thin-wall stainless steel steel plate is easy to punching drawing turned welt processing and fabricating pollution-free, and the simple cost of material manufacturing process of the same race is low.

In the utility model, cold water pipe is communicated with the welding connection of pipe reducing pipe with the tiny cold water of minor diameter 12mm, has reduced the weld length of interface weld seam, has reduced bonding area, reduces water leakage ratio.Cold water pipe 2 pipe diameter 76mm are communicated with pipe 7 reducing circular pipe communicateds with diameter 12mm pipe cold water, and the ability meeting with stresses is strong, can resist, eliminate the impact of thermal expansion shrinkage internal stress completely, cold water circular pipe communicated interface weld seam antileaking.Therefore, the technical scheme that technical solutions of the utility model and prior art file are recorded is compared cold water pipe and is connected fluid with header welding and does not communicate, and header inner chamber zone of heat liberation does not exist stress deformation, and the water-tight steady quality of all weld seams of header body is reliable.

Technical solutions of the utility model transformation this area heat exchanger is key, importance technological deficiency, overcomes technical problem, the little technical problem of solution heat transfer area that heat exchanger header body weld seam leaks.Reasonably the heat transfer area 45%～100% of the increase heat exchanger of science, overcomes a steam heating pipe in the irrational technological deficiency of cold water pipe tube chamber layout.The utility model in most of adjacent cold water pipe chamber, is set up the thin heating installation pipe of branched minor diameter to heater inlet pipe joint 10 at heating installation titting water outlet 9 ends, and small-diameter pipe can make the heat-transfer area of unit volume large, has produced unforeseeable technique effect.The heat that solution heat exchanger exchange outflow hot water is taken away with outflow hot water with the heat that newly enters cool water heating absorption equates, the hot water of internal memory flows out and newly enters cool water heating to the engagement technique problem flowing out, and overcomes water storage type heat exchanger and flows out the technological deficiency that hot water interrupts.

Entirety was communicated with heat conduction and had defect the only steam heating pipe of technical scheme of prior art and communicating pipe, its defect is undergone technological transformation and increases the heat transfer area of heat exchanger, invented the thin heating installation pipe combination of branched minor diameter and be communicated with formation circulating-heating fluid passage with header cavity.Change traditional concept and think that steam heating pipe must be the wrong views that pipe that diameter is thicker could be realized Fluid Circulation.Applicant overcomes technology prejudice, a traditional only thick steam heating pipe is decomposed into 6 thinner heat pipes, minor diameter 12mm pipe is arranged in each diameter 76mm cold water pipe tube chamber, many sub-minor diameter heating installation pipes are connected closure plate 6 and are welded to connect cavity connection with steam heating pipe in the mouth of pipe of cold water pipe two ends, overcoming the steam heating pipe of prior art content record or the connection of heating tube must be by welding series connection connection technology scheme communicating pipe, cause hot fluid resistance large, steam heating pipe or heating tube fluid center heat are not easy to be absorbed with inefficient technological deficiency by cold fluid exchange.The utility model has been taked the heating installation pipe mouth of pipe to be connected closure plate 6 with steam heating pipe and has been welded to connect the two ends mouth of pipe, and the two ends mouth of pipe and header cavity form the zone of heat liberation of amount of turbulence and shunting circulation, and fluid flow resistance is little.The described horizontal increase of branched thin heating installation pipe combination hot fluid metal surface and the conducting surface all standing of absorbing heat that contacts of cold fluid, the technical scheme of cold water tube chamber internal ratio prior art increases by 45%～100% heat transfer area, impels that branched thin heating installation pipe hot fluid center heat discharges fast, multitube passage heat transfer efficiency is high.Reached low-temperature heat source and effectively utilized, accelerated rate of heat transfer, technical solutions of the utility model exceeded expection less than technique effect good.

The utility model adopts stainless pipe welding UNICOM, incrustation scale adsorption time is adsorbed, extended to the inside and outside smooth generation incrustation scale of the tube wall difficulty or ease of stainless pipe of the same race, stainless steel tube reducing circular pipe communicated 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 (outwelling), 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 hot fluid heating outlet end and be detained and add that heat exchanger time is long, long flow path, the cold water entering contact with branched thin steam heating pipe metal covering again exchange heat absorption soon, the heat of hot fluid can all exchange and discharge cold fluid and absorbed.In steam heating pipe port of export cold water pipe chamber, set up branched minor diameter heating installation pipe, small-diameter pipe can make the heat transfer area of unit volume large, strengthen the cold water very first time and hot fluid partition and exchange needed heat transfer area acceleration heat transfer, low-temperature heat source is effectively utilized.Solved the cold water heat exchange titting water outlet outflow that water storage type heat exchanger internal memory hot water arranges from hot fluid heater inlet pipe joint 10 ends, the cool water heating exchange process hot water newly entering with the cold water inlet joint of hot fluid heating installation titting water outlet 9 end settings flows out the technical problem not being connected.

3,, as shown in Fig. 2,3,4,5,6, the cross sectional shape of described header body is round tube shape; Zigzag weld is logical in succession in turn between described branched cold water pipe 2 and adjacent cold water pipe 2, to be communicated with pipe 7 by cold water; In every cold water pipe 2 tube chambers, be provided with two above minor diameter heating installation pipes 1, minor diameter heating installation pipe 1 quantity arranging in every cold water pipe 2 tube chambers is identical or different; Hot fluid in minor diameter heating installation pipe 1 communicates with header inner chamber 12 and forms circulating heat transfer fluid passage.

4, the quantity that described every cold water pipe 2 tube chambers arrange described heating installation pipe 1 is from hot fluid heater inlet pipe joint 10 end cold water pipe 2 tube chambers arrange a heating installation pipe 1; To the adjacent branched cold water pipe tube chamber of hot fluid heating installation titting water outlet 9 end successively by increasing progressively or several times increase, to heating installation pipe 1 quantity of hot fluid heating installation titting water outlet 9 end cold water pipe 2 tube chambers be branched; The hot fluid of branched heating installation pipe 1 tube chamber and header inner chamber 12 form hot fluid amount of turbulence, multitube heat transfer cycle flow channel.

Current heating low-temperature heat source, 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 the heat of taking away and does not catch up with and occur that hot water outflow is not connected defects such as interrupting weak effect with the cold water heat exchange newly entering.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 heating.The utility model flows out in order to solve heat exchanger the technical problem that hot water interrupts, and heating exchanger takes branched cold water pipe and orifice plate inside header 4 to be welded to connect into entirety, forms cold fluid straight tube independent parallel flow circuit heat recipient fluid passage.The one: rational science connects branched cold water pipe increase moisture storage capacity can extend the exchange heat time, and it is long that the cold water entering is detained heat transfer flow time.The 2nd: branched minor diameter steam heating pipe can be set in the adjacent branched cold water pipe of the part tube chamber of hot fluid heating installation titting water outlet 9 ends increases heat transfer area, and the amount of turbulence of enhance fluid changes fluidized bed, strengthens conducting heat.The 3rd: the cold water that newly enters heat exchanger in order to reduce reduces effect with mixing of interior stored hot water, the utility model arranges cold fluid, and to be communicated with circular pipe communicated by cold water be independent parallel flowing heat transfer passage, the delay exchange and the operation length raising that increase cold fluid are efficient, realize water storage type heat exchanger outflow hot water and do not interrupt reaching Instant heating type heat transfer effect.The utility model compared with prior art have expection less than technique effect.

In the most of adjacent cold water pipe of exchanger heat fluid outlet chamber, branched thinner heating installation pipe being set is minor diameter 12mm, thin heating installation pipe forms the tower design stepped heating of step, its object allows the branched steam heating pipe metal covering that the very first time enters in cold water and first cold water pipe of heating installation titting water outlet 9 end of heat exchanger start exchange heat absorption, the hot water that branched cold water tube chamber stores extends the cold water newly entering and exchanges by flowing through second communicating pipe at first cold water pipe tube chamber, the 3rd by that analogy swap time long, the long flow path heat time is long, cold fluid is detained and adds heat exchange area long flow path at tube chamber, exchange to reach abundant exchange heat absorption flow process to hot fluid heater inlet pipe joint 10 pipeline section cold fluid outlet temperatures and basic identical the stopping of hot fluid tube wall temperature.Therefore, the heat exchange area that technical solutions of the utility model reasonably improve heat exchanger unit volume increases by 45%～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 utility model, in hot fluid port of export cold water tube chamber, arrange or increase branched thinner diameter 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, in each cold water pipe chamber of the little product of specification, all arrange 6 or prop up above the thin heating installation pipe of minor diameter 12mm, 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 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 the utility model cold water pipe chamber clinical practice increase the number of heating installation pipe tubule 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 minor diameter 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 arranges unreasonable fluid central heat source and can not get the technical problems such as effectively utilization.
