What the solid arrow in accompanying drawing meaned is the flow direction of cold water in heat transfer process, and what dotted arrow meaned is the direction of heating installation current.

The present invention adopts stainless steel to make, can install and use on family's heating network, but not only heating but also interchangeable hot water taking, with the daily water consumption such as carry out bathing, scrub.

Cold water pipe in the present invention is at least more than two, be communicated with pipe by cold water between the cold water pipe and weld in turn connection, be provided with closure plate in the mouth of pipe of cold water pipe, the closure plate upper punch is pressed with at least one heating installation pipe connecting hole, go back punching press on some closure plates cold water inlet/outlet pipe connecting hole is arranged, have at least a heating installation pipe to be connected and to be communicated with the heating installation pipe connecting hole welding of termination closure plate through the tube chamber of cold water pipe, the hot fluid in the heating installation pipe and the inner chamber of header form circulation.In this structure, the heating installation pipe connects without bend pipe, fluid resistance is little, cold water pipe and cold water are communicated with pipe in the outside connection of the casing of header, cold water pipe and cold water be communicated with pipe select different tube diameters, compression resistance strong, bear the thin-wall stainless steel pipe of internal pressure, strong with respect to the bearing capacity of header.

Select the stainless steel thin-wall pipe can save material, the corrosion resistance of stainless pipe is strong, produces incrustation scale and is easy to clean, and the water after heat exchange is pure clear, pollution-free, can be used as domestic water, also can have a bath.The stainless steel tube heat conduction of thin-walled is fast, with the tubing of same outer diameter as, compares, and cavity volume is large, stored hot water is many.Cold water pipe and cold water are communicated with pipe and are straight tube, directly outside exposed, once leak, also are easy to the welding maintenance, after the incrustation scale of heating installation circular tube external wall absorption cleans with acid, are communicated with pipe by direct-cooled water and are easy to discharge (or pouring out).

The present invention in use, the heating supply pipe network is supplied with water circulating pump, belong to closed cycle, the header inner chamber is the hot fluid circulation passage, the pressure born is the mechanical pressure that water circulating pump is supplied with, and is constant pressure, before heat exchanger dispatches from the factory, employing takes advantage of the coefficient pressure of 1.5 times to be detected it with the constant pressure of water circulating pump, can dispatch from the factory after qualified.Facts have proved, the weld seam of header zone of heat liberation is leakiness not, and steady quality is reliable.The water stored in the tube chamber of cold water pipe can produce thermal expansion stresses, and the ability that the cold water pipe meets with stresses can be made as 2 times of header voltage endurance capability.The bearing capacity of cold water circular pipe communicated can resist, eliminate the impact of thermal expansion shrinkage internal stress fully.Cold water pipe in the present invention and heating installation pipe all adopt stainless pipe to make, and the connection water storage between pipe has been eliminated the expansive force of header body cool water heating with respect to traditional heat exchangers, reduced stress deformation, has alleviated the bearing capacity of header inner chamber.Therefore, the advantage that the circular pipe communicated water storage is not easy to leak is more than traditional heat exchanger header body.

Steam heating pipe list branch pipe(tube) on average arranges that layout is unreasonable, heat exchange area is little, can not form amount of turbulence, rate of heat transfer is slow in the cold water tube chamber of the water storage type heat exchanger in the state of the art scheme.Cold fluid in heat exchanger under inactive state the intraluminal cold water temperature of cold water circle and heating installation to justify intraluminal hot fluid temperature identical, the cold water simultaneously entered when heat exchanger output hot water starts heating, because single the little cold water heat conduction be introduced into of steam heating pipe heat transfer area is not connected with the hot water of output and has occurred that hot water flow interruption heat transfer effect is poor slowly, moreover single Zhi Nuanqi pipe central hot measures and is lost less than effectively utilizing, therefore heat transfer effect is poor, and hot water can not continuous wave output.

The present invention adopts this technical measures, the branched thinner heating installation pipe of installation in adjacent cold water pipe is divided in the heat exchanger exit end, form the tower setting of step, increase heat transfer area 35% one 100% than prior art scheme, improve rate of heat transfer, divide the hot fluid of heating installation pipe branched thinner pipeline to change flow regime, increase flow velocity, improve the turbulence pulsation degree, effectively impel the heat at heating installation pipe center to be fully utilized to strengthen and conduct heat, add strong disturbance to change fluidised form, hot fluid is the heat transfer coefficient that the turbulence state increase is larger.Impel the cold water that is introduced into heat exchanger to contact fully and absorbed heat with the hot fluid wall at retention areas, the heat that heat exchanger output hot water is drained and the cold water simultaneously entered absorb heating installation pipe liberated heat and are directly proportional in retaining state is flowed through process.Cause the temperature that the very first time enters the heat exchanger cold fluid to improve constantly along heat-transfer area, the temperature of hot fluid descends along heat-transfer area is disconnected, and cold fluid flow absorbs heat and is circulated to heat exchanger and approaches the heater inlet pipe place and entered the basic identical heat transfer of thermal balance pipeline section temperature and stop in process.Therefore reduce the quantity of heating installation pipe in heating installation import pipeline section cold water pipe, namely fluid circulation channel of a heating installation pipe is installed in the cold water pipe of steam heating pipe import, not only save material but also improve heat transfer effect.

Therefore, the number that increases the heating installation pipe at heat exchanger heating outlet pipeline section makes up the disappearance that heating installation pipe Yin Wendu reduction causes the required temperature of cold water, the number that reasonably increases the heating installation pipe in cold water pipe chamber cold fluid obtains the heat output of maximum possible, thereby the heat energy of fluid is rationally utilized, effectively prevent the discontinuity of prior art heat exchanger output hot water.Technical solution of the present invention reaches fully effectively utilizes heat energy, and its intensity is enough, heat transfer property is reliable, reasonable in economy, assurance meet needed hot water flow in the process of having a bath, and it is uninterrupted continuously that its technique effect obtains best hot water flow.

In the present embodiment, the header orifice plate of described D font header is converted into the channel steel type strip plate, during the punching stretching round mouth, can reduce the inside contraction distortion in the horizontal phase of edges of boards edge, edges of boards uneven, be not easy to merge or butt-welded defect, rectangular flat board is converted into the intensity that channel steel shape can increase orifice plate, the channel steel type orifice plate can increase the ability of orifice plate opposing stress deformation, reduce in welding process and be subject to thermal stress deformation, effectively prevent that four weld seams of header from leaking.

In the present embodiment, the merging of semi arch plate forms the round tube shape header, and the cold water pipe engages the anti-planted agent's ability of formation reduced pipe UNICOM with the semi arch orifice plate strong, and effectively opposing or the minimizing of elimination welding deformation are leaked.

The above-mentioned design of the present invention, set positions is imported and exported in arranging according to the flow process of heating installation pipe network closed cycle of heating installation pipe, in heat exchanger heating installation water outlet pipe end cold water pipe, step is tower arranges branched thinner heating installation pipe, thinner heating installation pipe center heat is easy to by the cold fluid favorable for absorption, thereby the heat of fluid is fully changed.The cold fluid that makes the very first time enter heat exchanger in the delay process by Fast Heating, thereby when specific heat is definite value, the variation of fluid temperature (F.T.) is directly proportional to the heat of absorption (or heat release), enters cold water in the time of heat exchanger output hot water and absorbs heat to heater inlet pipe mouth in the process of flowing through substantially to reach temperature equal.Therefore, good effect of heat exchange of the present invention, solved the technical problem that prior art scheme water storage type heat exchanger can not provide the hot water continuous wave output.
