Current heating low-temperature heat source, technical scheme heating installation exchange water heater steam heating pipe of prior art is little at cold water pipe tube chamber coiling heat transfer area, and the hot water that exchange rate stores slowly 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 water storage type heat exchanger in the quiescent state cold fluid of cold water pipe tube chamber and the hot fluid of steam heating pipe tube chamber is equal temperature, when using interchanger to flow out hot water, the cold water synchronously entering 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 middle part cold water tube chamber and the intraluminal cold fluid of heating installation entrance point cold water and heating installation tube chamber fluid or there is not heat exchange in equal temperature, use heat exchanger to flow out cold water that internal memory hot water newly enters because the delivery time is long promotes hot water and flows through and exchange to middle part and flow to hot fluid heating installation entrance point cold water heat exchange titting water outlet exit because the rate of heat exchange of the low fluid of the little temperature of heat transfer area does not catch up with and flow out hot water and interrupt cooling off weak effect.
Current central heating toll administration, point family independent pipe network design low-temperature heat source heating.The technical problem of hot water interruption is flowed out in the present invention in order to solve heat exchanger, heating exchanger is taked branched cold water pipe welding UNICOM to form overall sheet and formed straight tube parallel fluid circulation heat absorption passage.One is: rational science connects branched cold water pipe increase moisture storage capacity can extend swap time, and it is long that the cold water delay entered from hot fluid outlet ports end cold water pipe portion adds heat exchange process.Two are: the combination steam heating pipe of the branched narrow tube composition arranged in the part branched cold water pipe tube chamber that hot fluid heating outlet pipe joint 8 end is adjacent increases heat transfer area, and the amount of turbulence of enhance fluid changes fluidized bed, strengthens heat transfer.Three are: in order to prevent the cold water newly entering heat exchanger from reducing effect with mixing of interior stored hot water, and 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 that increase cold fluid improve 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 adjacent cold water pipe chamber of exchanger heat fluid outlet major part, thin heating installation pipe forms step tower design stepped heating, and its object very first time branched steam heating pipe metal covering of combination heating installation pipe entered in the cold water of heat exchanger and heating outlet pipe joint 8 end first cold water pipe starts to exchange and absorbs heat.The hot water that branched cold water pipe chamber stores is extended the cold water that newly enters and exchanges at first cold water pipe tube chamber and to be flowed through to by cross over pipe that second, the 3rd is grown by that analogy swap time, the long flow path heat time is long, cold fluid is detained at tube chamber and adds heat exchange area long flow path, fully exchange heat absorption flow process to hot fluid heating installation inlet connector tube 7 pipeline section to reach, stop substantially identical with hot fluid tube wall temperature exchanges cold fluid outlet 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 is compact, science, economical rationality, realize output hot water amount large, flow out the unbroken technique effect of hot water continuously.
In the present invention in hot fluid outlet ports end cold water tube chamber by increasing the combination heating installation pipe 17 arranging or increase branched thinner diameter heating installation pipe composition, accelerate rate of heat transfer, improve heat transfer effect.Also the number of heating installation pipe can be designed flexibly according to product specification, 6 or more minor diameter 12mm are all set in each cold water pipe chamber of the little product of specification and combine heating installation pipe, can realizing small dimension product, also to flow out hot water uninterrupted, the product that specification is larger, tiny steam heating pipe circle 4 minor diameter 12mm are set in the adjacent cold water pipe chamber of hot fluid outlet ports end major part and combine heating installation pipe, arranging an only heating installation pipe in the cold water pipe chamber that hot fluid entrance point is corresponding is that output channel is used, so namely, save material, ensure heat transfer effect again.
In the present invention, described branched thin heating installation pipe heat conduction not only increases the heat exchange area of heat exchanger, and combination heating installation pipe is set in each cold water pipe chamber, import department and the exit of combination heating installation pipe form repeatedly amount of turbulence, the fluidized bed of effective alter, accelerate rate of heat transfer, cold fluid coolant-temperature gage increases in gradient, the cold water being introduced into heat exchanger tube chamber is impelled to contact to look swap time at the many partitions of the first exchange area and hot fluid and fully exchange heat absorption, the hot water heat of draining that heat exchanger flows out and the cold water simultaneously entering heat exchanger absorb at retaining state or flow through in process and combine heating installation pipe liberated heat and be directly proportional, the temperature causing the very first time to enter heat exchanger cold fluid improves constantly along metal heat transfer face, the temperature of hot fluid is disconnected along metal heat transfer face to decline, cold fluid flow absorbs recycle heat and stops to the substantially identical heat transfer of hot fluid heating installation import thermal balance pipeline section fluid temperature (F.T.) in process.Therefore, in exchanger heat fluid heating outlet pipeline section cold water pipe, arranging the only steam heating pipe of technical scheme that the heat conduction of tiny combination heating installation pipe makes up prior art because of the reduction of heat supply temperature causes the disappearance of area needed for cold water and temperature and weak effect.The number combination heating installation pipe that the arranging of cold water pipe chamber of the present invention clinical practice increases tubule then cold fluid obtains the heat output of maximum possible, thus make the heat at hot fluid center rationally be discharged utilization, effectively prevent heat exchanger from flowing out the interruption of hot water, set up the combination heating installation pipe branched pipe heat conduction liberated heat be made up of minor diameter steam heating pipe, effective solution heat exchanger heat transfer area is little, and stored hot water flows out the cold water covered and exchanges the technical problem do not caught up with.Solve an only steam heating pipe to arrange unreasonable fluid central heat source and can not get the technical problems such as effective utilization.Therefore, technique scheme of the present invention reaches and fully effectively utilizes heat, saves the material energy, its intensity is enough, heat transfer property reliable, reasonable in economy, compact conformation, ensures to meet hot water flow required in process of having a bath.Comprehensively above-mentioned, this technical scheme effectively solves 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.
