Abstract
A heat exchanger with offset pipe bundles in parallel connection can reduce the volume and improve the heat efficiency. A plurality of offset heat exchange pipes are connected to pipelines in parallel, one ends of the heat exchange offset pipes are connected with a feeding pipe, the other ends of the heat exchange offset pipes are connected with a discharging pipe, a pipe wall heat exchange area of the heat exchanger is enlarged by over twice of that of a heat exchanger with a single offset pipe, no fin accessory is required, the heat exchanger can be applied widely in fields of air conditioners and gas water heaters, the problem that main heat exchangers of gas water heaters can not absorb latent heat is solved, and manufactured gas water heaters are not required to be dismantled frequently and the heat exchangers of manufactured gas water heaters are not required to be cleaned.
Description
Technical field
The utility model belongs to the gas heater field.Be a kind of parallel heat exchanger of circuitous tube bank of augmentation of heat transfer specifically.
Background technology
Gas heater is to adopt circuitous single tube fin formula heat exchanger at present, and the thermal efficiency of this structure is low, and the big more thermal efficiency of heat exchanger tube diameter is low more, and fin does not have the effect of direct heat transfer, in fact mainly still will lean on the tube wall of heat exchanger tube to come heat exchange.Under the powerful heat exchange situation, this is a technical bottleneck, the gas heater aspect; Also be to increase condensing heat exchanger in addition; Improved cost, complex structure, waste material, soon will the accumulate smoke dust between the fin of artificial coal gas water heater, cause flue to block.
Summary of the invention
are in order to solve the high problem of heat exchanger heat inefficiency, manufacturing cost of prior art; Basis is practical to provide a kind of circuitous tube bank parallel heat exchanger; Save fin, increase the heat exchange area that small quantity of material has just enlarged heat exchanger tube greatly.
are originally practical to be the parallel heat exchanger of a kind of circuitous tube bank specifically.Mainly form a heat exchange body by influent stream pipe, outflow tube and circuitous heat exchanger tube doublet; Circuitous heat exchanger tube is made up of straight tube and bend pipe, and circuitous heat exchanger tube pipeline has two or more, is connected in parallel on the pipeline of influent stream pipe and outflow tube; Fluid in the pipe comes out just to be diverted in every circuitous heat exchanger tube of parallel connection from the influent stream pipe; Carry out being flowed to outflow tube again after the heat exchange and flow away, during heat exchange, the work that several circuitous heat exchanger tubes are united.The caliber that the caliber ratio of circuitous heat exchanger tube advances (going out) stream pipe is little; When the quantity of circuitous heat exchanger tube is four; And the caliber sum is when equaling into (going out) stream pipe caliber; The tube wall girth of circuitous heat exchanger tube but is into (to go out) 2 times of stream pipe, and 2 times of just circuitous heat exchanger tubes are to the tube wall that advances (going out) stream pipe.
the utility model has the advantages that: fin is changed into need not be increased material behind the heat exchanger tube and just can improve the heat exchanger effectiveness of heat exchange greatly; Reduced the production cost of condensed type combustion gas water heater greatly.
Below in conjunction with accompanying drawing and embodiment to this practical further specifying.
Description of drawings
Fig. 1 is the cross section structural map of the utility model embodiment.
Fig. 2 is the front schematic view that the utility model is applied to gas heater embodiment.
1. outflow tubes among Fig. 1,2. influent stream pipe, 3. circuitous heat exchange is changed, 4. straight tube, 5. bend pipe, 6. pipe section.
1. outlet pipes among Fig. 2, the coil pipe of 2. intaking, 3. circuitous heat exchanger tube, 4. straight tube, 5. bend pipe, 6. water (flow) direction arrow.
The specific embodiment
In the embodiment shown in fig. 1, form a parallel heat exchanger of circuitous tube bank by four circuitous heat exchanger tubes (3), outflow tube (1), influent stream pipe (2).Every circuitous heat exchanger tube (3) is formed by connecting five straight tubes (4) and four bend pipes (5) respectively.Form a circuitous pipeline.Circuitous heat exchanger tube (3) one ends are communicated with outflow tube (1), and the other end is communicated with influent stream pipe (2), and four circuitous heat exchanger tubes (3) are communicated with influent stream pipe (2) and outflow tube (1) with parallel form.Tube fluid is diverted to every circuitous heat exchanger tube (3) after influent stream pipe (2) comes out; Carry out confluxing into outflow tube (1) after the heat exchange; The caliber of every circuitous heat exchanger tube is 1/4 of influent stream pipe (2) or outflow tube (a 1) caliber, and circuitous heat exchanger tube (3) tube wall girth sum is influent stream pipe (2) or outflow tube (1) tube wall girth 2 times.
In embodiment illustrated in fig. 2; The gas heater outer wall of combustion chamber is a water coil pipe (2) into; One end of one end and the outlet pipe (1) of water inlet coil pipe (2) several circuitous heat exchanger tubes (3) that are being connected in parallel; Make whole pipe form the passage of parallel connection, every straight tube (4) is arranged in parallel, and integral body becomes the angle of inclination shape with the burner flame plane.Running water flows along water (flow) direction arrow (6), absorbs the heat of straight tube (4) tube wall, and the condensed water that straight tube (4) pipe outer wall condenses can be unlikely to drop onto on the burner along the pipe range direction toward dirty.
Claims (1)
1. one kind is made a circulation to restrain parallel heat exchanger; Form by influent stream pipe, outflow tube and circuitous heat exchanger tube; Circuitous heat exchanger tube is formed by connecting straight tube and bend pipe, it is characterized in that: circuitous heat exchanger tube pipeline has two or more, is connected in parallel on the pipeline of influent stream pipe and outflow tube.
