5, as shown in Figure 13, Figure 15, Figure 16, often propping up described heating installation pipe 1 quantity arranged in cold water pipe 2 tube chamber is one, two or branched; Often prop up heating installation pipe 1 quantity arranged in cold water pipe 2 tube chamber identical to the quantity of often propping up heating installation pipe 1 in cold water pipe 2 tube chamber that heating installation inlet connector tube 5 end is adjacent successively from heating outlet pipe joint 11 end; Or heating outlet pipe joint 11 end adjacent often to prop up the quantity being provided with heating installation pipe 1 in cold water pipe 2 tube chamber not identical more than the quantity of heating installation pipe 1 in cold water pipe 2 tube chamber of heating installation inlet connector tube 5 end.
6, as shown in Figure 6, the quantity being provided with described heating installation pipe 1 in cold water pipe 2 tube chamber that manifold arranges flexibly is one, two or branched; The intraluminal quantity of cold water pipe 2 that the quantity being installed with heating installation pipe 1 in cold water pipe 2 tube chamber of described manifold arrangement arranges from described hot fluid heating outlet pipe joint 11 end to described hot fluid heating installation inlet connector tube 5 end is successively decreased by propping up; Or describedly often prop up the quantity being installed with described heating installation pipe 1 in cold water pipe 2 tube chamber, from hot fluid heating installation inlet connector tube 5 end cold water pipe 2 tube chamber is installed with a heating installation pipe 1; Increase progressively or several times increase by propping up in hot fluid heating outlet pipe joint 11 end adjacent manifold arrangement cold water pipe 2 tube chamber successively, heating installation pipe 1 quantity to hot fluid heating outlet pipe joint 11 end cold water pipe 2 tube chamber is branched; In branched heating installation pipe 1 tube chamber, the circulation of hot fluid multitube strengthens heat transfer.
Described heating installation water storage type heat exchanger, the cold fluid of cold water pipe tube chamber and the hot fluid of heating installation pipe tube chamber are equal temperatures in the quiescent state, 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 heating installation pipe of hot fluid heating outlet pipe joint 11 end, at this moment middle part cold water tube chamber and the intraluminal cold fluid of heating installation inlet connector tube 5 end cold water and heating installation tube chamber fluid or there is not heat exchange in equal temperature, use heat exchanger flow out internal memory hot water because of the delivery time longer, the cold water promotion hot water newly entered flows through and exchanges to middle part, because heat transfer area is little and the rate of heat exchange of the unreasonable heat source temperature of heating source area layout low fluid does not again catch up with and flow to hot fluid heating installation inlet connector tube 5 end cold water exchanged heat water outlet pipe joint 3 place and flow out hot water and interrupt cooling off weak effect.
Not only heating exchanger of the present invention is taked to be welded to connect integrally heating installation sheet between branched cold water pipe and is dispelled the heat but also exchange hot water bathing for, form cold fluid straight tube independent parallel flow circuit heat recipient fluid passage.One is: 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 entered is detained heat transfer flow time.Two are: arranging branched 6 minor diameter 12mm heating installation pipes in the part branched cold water pipe tube chamber that hot fluid heating outlet pipe joint 11 end is adjacent increases heat transfer area, and the amount of turbulence of enhance fluid changes fluidized bed, strengthens heat transfer.Three are: reduce effect in order to reduce the cold water newly entering heat exchanger with mixing of interior stored hot water, cold fluid cavity of the present invention arranges cold fluid flow distribution plate 7, shunted by cold fluid flow distribution plate 7 and form PARALLEL FLOW heat recipient passage, what increase cold fluid adds heat retention length swap time and operation length, improve heat exchange efficient, realize water storage type heat exchanger and flow out the heat transfer effect that hot water does not interrupt reaching practicality.The present invention compared with prior art have expection less than technique effect.
In actual installation, exchanger heat fluid heating outlet pipe joint 11 and cooling water inlet pipe joint 12 overwhelming majority are arranged on the bottom of heat exchanger, arrange branched thinner heating installation pipe in lower part adjacent cold water pipe chamber is minor diameter 12mm for this reason, thin heating installation pipe forms step tower design stepped heating, its object allows the very first time branched steam heating pipe metal covering entered in cold water and heating outlet pipe joint 11 end first cold water pipe of heat exchanger contact to start to exchange and absorb heat, the hot water that branched cold water tube chamber stores is extended the cold water that newly enters and to be divided by cold fluid flow distribution plate first cold water pipe tube chamber exchange and flow through second, 3rd by that analogy swap time long, the long flow path heat time is long, cold fluid is detained at tube chamber and adds heat exchange process prolongation, thus reach and fully exchange heat absorption flow process and exchange to stop substantially identical with hot fluid tube wall temperature of hot fluid heating installation inlet connector tube 5 pipeline section cold fluid outlet temperature.Therefore, technical solution of the present invention reasonably improves heat exchange area increase by 50% ~ 100% heat transfer area of heat exchanger unit volume.This invention project organization is compact, hot water flow out do not interrupt continuously user satisfied, economical and practical, scientific and reasonable, prolong life, durable, economize on resources.
