Mouthful, have heating channel outlet in the second water box, it is parallel on heat collector to be connected respectively with the first water box, the 3rd water box equipped with both ends
The 3rd water main, the 4th water main that first water main, the second water main, both ends connect respectively with the second water box, the 3rd water box,
Both ends are respectively provided in first water main, the second water main and stretch out the first water box, the first inner tube of the 3rd water box respectively, in second
Pipe, be respectively provided in the 3rd water main, the 4th water main both ends stretch out respectively the second main water box, the 3rd main water box the 3rd in
Pipe, the 4th inner tube, the first inner tube stretch out one end and the life feeder connection fittings of the 3rd water box and stretch out the first water box
One end that one end stretches out the first water box by the first connecting tube with the second inner tube connects, and the second inner tube stretches out one end of the 3rd water box
The one end for stretching out the 3rd water box with the 3rd inner tube by the second connecting tube connects, and one end that the 3rd inner tube stretches out the first water box passes through
One end that 3rd connecting tube stretches out the first water box with the 4th inner tube connects, and the 4th inner tube stretches out one end of the 3rd water box and life is led to
Road exports the cross-sectional shape respectively annular shape of fittings, each water main and each inner tube, the first water main and the first inner tube
Between have first supervisor's spring being spirally wound on the first outer wall of inner tube, Spiral distribution has the first inner tube bullet on the first inner tube wall
Spring has second supervisor's spring being spirally wound on the second outer wall of inner tube, in the second inner tube between the second water main and the second inner tube
Spiral distribution has the second inner tube spring on wall, is spirally wound between the 3rd water main and the 3rd inner tube on the 3rd outer wall of inner tube
3rd is responsible for spring, and Spiral distribution has the 3rd inner tube spring on the 3rd inner tube wall, has spiral shell between the 4th water main and the 4th inner tube
Rotation is wrapped in the 4th supervisor's spring on the 4th outer wall of inner tube, and Spiral distribution has the 4th inner tube spring on the 4th inner tube wall.
Above-mentioned each water main thickness of pipe wall is 0.5~1mm.
Above-mentioned each supervisor's spring is tubulose, and thickness of pipe wall is 0.3~1mm, and by warming oneself, channel entrance enters in water main
Water some also to be flowed through through being responsible for the passage that is formed in spring, fully absorbed heat, the thermal efficiency is high.
The cross sectional shape of above-mentioned each supervisor's spring is annular shape, and annulus outer diameter is 3.5~10mm.
The screw pitch of supervisor's spring in above-mentioned each water main is 10~20mm.
The screw pitch of above-mentioned each inner tube spring is 5~10mm, by the corrosion resistant solid material system of a diameter of 1~2.5mm
Into.
Water main carries out heat exchange with the water in pipe：Water main wall is thicker, and heat is transmitted to time of water and just grows, thus it is more thin more
It is good, but to consider the relation of water main intensity and corrosion resistance, therefore wall thickness uses 0.5-1 ㎜ just.In addition the heat transfer of water
It is very slow, it is 0.2 ㎜ per second generally in the heat transfer rate of normal-temperature water, certain temperature more high heat transfer is faster, and increases into multiple.Therefore
General requirement increases flow-disturbing, increases the disturbance of water, improves the heat transfer rate of water.Flow-disturbing is to use tubular material in the utility model
Make spring-like, it can be evenly spaced with water main by inner tube, makes inner tube in the centre of water main, moreover it is possible to make the water of water main into
Helical flow plays the role of flow-disturbing, and being responsible for spring can also be flowed using tubular material, that is, inside
Water has heat transfer extraordinary effect.Namely water mixes again through feeder connection of warming oneself into the first water box by water box
Afterwards, the gap between water main and inner tube is passed through（There is supervisor's spring in gap）, make the spiral movement of water, water allowed mutually to hand over
Melt, reach better heat exchange, and it is also tubulose to be responsible for spring, also wants circulating water, and here it is the heat exchange of heating passage.Through overheat
Water after exchange is through channel outlet outflow of warming oneself, thermal efficiency height.
Domestic water exchanges heat：Cold water enters inner tube through life feeder connection connector, is carried out by interior one layer of hot water in tube outside
Heat exchange, also, internal tube is also equipped with spring, and the water for reaching internal tube carries out flow-disturbing stirring action, to improve the thermal efficiency.
Water after heat exchange is through channel outlet connector outflow of living, for people's domestic water.
The utility model has the following advantages：
1st, water main, inner tube are pipe, facilitate processing, prevent and burn out, greatly improve product qualification rate, water main,
Inner tube quantity is respectively 4, than similary model heat exchanger weight reduce 200-300 grams, substantially reduce cost, reduce copper
The consumption of material, saves material, and qualification rate is high；
2nd, using supervisor's spring, inner tube spring, heat moment is taken away, improved the heat-exchange capacity of water, reduces material and disappears
It consumes and greatly improves rate of heat exchange, the thermal efficiency is high；
3rd, safety.

Flue gas flow direction：By burner combustion, the exchange of heat is carried out through over-heat-exchanger, after being absorbed heat by heat absorbing sheet, then is connect
Petticoat pipe, burning waste gas are just discharged.
Combustion system：First, the flame envelope of flame combustion heat absorbing sheet lower part in heat collector, the temperature one of combustion of natural gas
As at 800-1200 DEG C or so, this temperature range is influenced by combustion system, offering oxygen way etc.；By heat after heat absorbing sheet heat absorption
Each water main welded together with heat absorbing sheet is passed to, each water main transfers heat to water again, just will be in each water main
Water heated, here it is heating passage heat supply.The followed by heat supply of life passage, be by the hot water for passage of warming oneself,
The inner tube of the life passage of each inner tube and connecting tube composition is passed to, inner tube passes to the water of life passage again.
Due to lower part, a part of heat of central absorbent, the temperature on top is more lower, generally exist on heat absorbing sheet top
Between 110-300 DEG C, according to inference, in general solstics can be some larger apart from pipe inner wall, too big waste of materials again,
Absorption and releasing contribution to heat is little, that is to say, that it is recommended that solstics is apart from pipe inner wall no more than 40 ㎜.
Heat absorbing sheet and the heat transfer of water main welding：There are two types of modes at present for welding.A kind of to use soldering, one kind is to use
Hot dipping slicker solder welds together heat absorbing sheet and water main.Regardless of welding manner, all there is the quality connected, welding
It conducts heat well all right, the bad of welding will generate thermal resistance, cause heat transfer not smooth, once heat transfer is not smooth, heat is just gathered at this, very
The temperature at this will rise soon, also be easy to cause at this and first burn out, and just progressively be spread at the place of burning out after burning out, cause large area
It burns out.
Above-described embodiment is that the above of the utility model is further described, but should not this be interpreted as this reality
Above-described embodiment is only limitted to the scope of new above-mentioned theme.It is all that this practicality is belonged to newly based on the technology that the above is realized
