Preferably, the heat collecting sheet is perpendicular to heat exchanging water pipe's outer surface and is provided with some, every two neighboring heat collecting sheet
Between be provided with spacing.
Using such scheme, the heat collecting sheet for making the arrangement for being capable of rule on heat exchanging water pipe most.Semiorbicular projection can
Heat exchanging water pipe's external surface area is increased, the contact area with combustor is increased, heat exchange rule is improve.
Preferably, the heat collecting sheet is that semiorbicular lamellar is raised.
Using such scheme, the outer surface of the heat exchanging water pipe that preferably can coincide, the heat absorbed by heat collecting sheet is enable more preferably
Be delivered in heat exchanging water pipe.
Preferably, also including top cover, the top cover is welded on the outer surface of heat exchanging water pipe to cover described in any two
The gap formed between heat exchange straight tube.
Using such scheme, the gap covered between heat exchanging water pipe with top cover, prevent the heat in combustor from passing through
Gap between heat exchanging water pipe is scattered and disappeared, and improves the heat utilization efficiency of heat exchanging water pipe.
Preferably, also including combuster, the heat exchanging water pipe, heat collecting sheet and top cover constitute main heat exchanger, described
Main heat exchanger is parallel to combustor and the main heat exchanger is fixedly connected with combustor, and the heat collecting sheet is located near burning
The side of room.

Specific embodiment
This utility model is described in further detail below in conjunction with accompanying drawing.
Disclosed in the present embodiment, a kind of gas-heating water heater, shown in Figure 1, including main heat exchanger 1 and combustor
2, main heat exchanger 1 is welded with the one of heat collecting sheet 3 and faces down and is welded on the top of combustor 2 in parallel.Intensive heat collecting sheet 3 is increased
External surface area of the heat exchanging water pipe 4 near 2 that face of combustor, absorbs the heat in combustor 2 to the full extent.Main heat exchanger 1
Overall be made up of rustless steel, it is therefore prevented that the current in heat exchanging water pipe 4 and the condensed water on heat collecting sheet 3 are for main heat exchanger
1 corrosion, improves the service life of gas-heating water heater.
Shown in Figure 2,4 shape of heat exchanging water pipe is serpentine-like and 7 length of straight tube that exchanges heat is identical, such as the water pipe of several S-shapeds
It is connected.Whole main heat exchanger 1 is presented a shape for being similar to cuboid, is provided with thermal-arrest in the side near combustor
Piece 3.The heat collecting sheet 3 perpendicular to 4 outer surface of heat exchanging water pipe and be provided with it is some, between being provided between two neighboring heat collecting sheet 3
Away from.The heat collecting sheet 3 is that semiorbicular lamellar is raised.And the space only minimum between straight tube 7 that exchanges heat of arranged adjacent, and
It is trapezoidal casting coping 6 that cross section has been welded in the top in gap, blocks the dispersed heat from gap, it is therefore prevented that combustor
The waste of heat in 2, causes the waste of the energy, improves heat utilization efficiency.
Shown in Figure 3, the external screw thread at 7 two ends of straight tube that exchange heat is arranged enables heat exchange straight tube 7 convenient and heat exchange bend pipe 8
Screw thread dismounting is fixed, and facilitates the replacing of 4 broken parts of heat exchanging water pipe.
Shown in Figure 4, flow-disturbing projection 5 is shape that is oval and slowly gathering towards centre upwards for bottom surface, flow-disturbing projection 5
All it is close to the inwall of heat exchanging water pipe 4, it is in arc surface that surface is the junction of the flow-disturbing raised 5 and inwall of smooth arc surface, is not had
Have and produce unnecessary gap and gap, it is to avoid be capable of the dead angle of sediment incrustation.4 inwall of heat exchanging water pipe is in smooth surface, can be with
4 inwall of original heat exchanging water pipe gap that may be present is reduced, the possibility of incrustation scale deposition is reduced.Strengthen heat exchanging water pipe 4 simultaneously
Heat exchange rule.Being welded on 4 inwall of heat exchanging water pipe for flow-disturbing 5 helical arrangement of projection, makes flow-disturbing projection 5 for the impact of current
It is overlapped mutually, makes water turbulence state more violent.In the cross section of heat exchanging water pipe 4, the height of flow-disturbing projection 5 is less than horizontal stroke
/ 10th of/3rd of diameter of section, simultaneously greater than cross-sectional diameter, such flow-disturbing projection 5 will not because of excessive and
Blocking heat exchanging water pipe 4, will not have the effect for making water turbulence because of too small yet.Have and only in heat exchange 7 spiral of straight tube
It is provided with some flow-disturbing projections 5.The flow-disturbing projection 5 of diverse location makes the current in heat exchanging water pipe 4 for 4 inwall of heat exchanging water pipe is rushed
Hit more comprehensively, reduce the deposition of incrustation scale in current, while washing away the deposited incrustation scale of 4 inwall of heat exchanging water pipe, reduce interior
The incrustation scale for having been deposited on wall.Only flow-disturbing projection 5 is welded in 7 part of heat exchange straight tube, be to change current in original heat exchange straight tube 7
Situation about directly flowing through, by flow-disturbing raised 5 so that turbulent condition occur in the current in heat exchange straight tube 7, reaches impact and changes
The effect of the inwall of hot-water line 4；When current are through heat exchange bend pipe 8, because the bending part in heat exchange bend pipe 8 can occur current stream
The change in dynamic direction, makes current also realize exchanging the inwall that impacts of hot-bending pipe 8, therefore increases without welding flow-disturbing projection 5
Impact of the current to inwall.
In gas-heating water heater when in use, current are begun to warm up in heat exchanging water pipe, and heat collecting sheet will burn indoor
After heat absorption, start heat exchange, the preferential heating of current of heat exchanging water pipe lower half by heat exchanging water pipe and current.In current
Affected by flow-disturbing projection in flowing, flow direction there occurs change, make current be in turbulent condition, so as in heat exchanging water pipe
Top and the bottom current start mixing, and temperature becomes uniform.Because the raised surface of pipe inner wall and flow-disturbing is all arc surface, in current
Entrained impurity will not find the gap that can be deposited on heat exchanging water pipe's inwall, also because the turbulent condition impurity quilt of current
Current drive, and will not deposit in heat exchanging water pipe's inwall.Meanwhile, deposited incrustation scale on heat exchanging water pipe's inwall, by the water of turbulent flow
Stream constantly impacts, and by erosive wear slowly, leaves heat exchanging water pipe's inwall, extends the service life of gas-heating water heater.
This specific embodiment is only which is not to restriction of the present utility model, ability to explanation of the present utility model
Field technique personnel can make the modification for not having creative contribution after this specification is read as needed to the present embodiment, but
As long as all being protected by Patent Law in right of the present utility model.
