The specific embodiment
According to the accompanying drawing of the combustion chamber of gas fired-boiler of the present invention, specifically describe below, but identical with the structure in past of describing in the prior art, or similarly part adopts same title and same label.
Fig. 2 is the inner composition diagram in the side of gas fired-boiler of the present invention combustion chamber, and Fig. 3 is the positive inner composition diagram of gas fired-boiler of the present invention combustion chamber.
In addition, Fig. 4 is an another embodiment of the present invention, and the inner composition diagram in the side of gas fired-boiler combustion chamber, Fig. 5 are another embodiment of the present invention, the positive inner composition diagram of combustion chamber shown in Figure 4.
As shown in Figures 2 and 3, the combustion chamber of gas fired-boiler of the present invention have with prior art in the similar structure in combustion chamber described.
That is, this combustion chamber 10 forms like this, that is, it comprises heat supply water inflow pipe 25, and this heat supply water inflow pipe 25 is coiled type and is formed on the shell 15 of combustion chamber 10, by heat supply flow inlet 20, heat supply water is flowed into; Heat-exchange tube 30, this heat-exchange tube 30 adopt the combustion heat of burner when above-mentioned heat supply water flows, directly carry out heat exchange; Heat supply water outflow portion 40, this heat supply water outflow portion 40 make by the heat supply water of above-mentioned heat-exchange tube 30 heating and discharge.
Obviously, on the outer peripheral face of above-mentioned heat-exchange tube 30, be provided with the heat absorption fin 35 that is used to make the rate of heat exchange raising.
At this moment, the combustion chamber of gas fired-boiler of the present invention is not limited to the gas fired-boiler in on-condensing, and it is applicable to the gas fired-boiler of condensing.
Here, the essence of technical scheme of the present invention is characterised in that, the inside in above-mentioned combustion chamber 10 is provided with the heat supply water inflow pipe 25 of the outside be wound in combustion chamber 10 in the past, and the outside at the shell 15 of above-mentioned combustion chamber 10 has heat insulating member 45.
Like this, by above-mentioned heat supply water inflow pipe 25 being arranged at the inside of combustion chamber 10, compensated its volume that occupies by being wound in the outside, so 10 miniaturizations of above-mentioned combustion chamber, outward appearance is succinct, makes overall compact.
In addition, be arranged at the inside of combustion chamber 10, increase heat transfer area, can absorb more heat directly, indirectly by the heat supply water inflow pipe 25 that heat supply water will be flow through.
In addition, on the outer wall of the shell 15 of above-mentioned combustion chamber 10, heat insulating member 45 is set, thus that combustion chamber 10 is isolated towards the thermal source of outside drain, can be in the combustion chamber 10 inside, absorb more heat.
On the other hand, as shown in Figure 4 and Figure 5, in an also embodiment of the present invention, form above-mentioned heat-exchange tube 30, it is characterized in that, this pipe is formed by dual structure, the good copper pipe 30a of conductivity is adopted in the inside of this pipe, aluminum tube 30b is adopted in the outside of this pipe, then, forms the heat absorption fin 35 on the outer peripheral face that is arranged at heat-exchange tube 30 by the roll forming mode.
Like this, the aluminum that the pyroconductivity that above-mentioned heat-exchange tube 30 is changed employing in the past is lower and the pipe of stainless steel material, and adopt the good copper pipe 30a of pyroconductivity, form dual structure in inside, thus, obviously can improve the thermal efficiency, also can prevent inner corrosion.
In addition,, form above-mentioned heat absorption fin 35, thus,, simplify the advantage of qualification rate raising so have procedure of processing without the complex steps of the hard solder in past owing to change the roll forming mode into from the hard solder mode in past.
Obviously, though not shown in the drawings,, also can form like this, that is, at this moment, above-mentioned heat-exchange tube 30 is made of the copper pipe as a whole, has single structure, and simultaneously, the endothermic tube 35 that is arranged on the outer peripheral face of heat-exchange tube 30 forms by the roll forming mode.
Effect and effect to the combustion chamber of the gas fired-boiler of the present invention that forms by scheme as described above is described below.
If adopt from outside leaked-in air, at the said burner burning gases, then calory burning in the combustion chamber 10 internal delivery, by the inwall that is formed at combustion chamber 10, the heat supply water inflow pipe 25 that heat supply water is flowed into carries out preheating to heat supply water.
Then, above-mentioned heat supply water is directly heated by in the heat-exchange tube 30, and heat supply water is discharged by heat supply water outflow portion 40 after accumulation of heat, being discharged in the atmosphere of burning.
At this moment, heat insulating member 45 can be passed through in the inside in above-mentioned combustion chamber 10, carries out further a large amount of heat exchanges.
In addition, because above-mentioned heat supply water inflow pipe 25 is not arranged at the outside of combustion chamber 10, and be arranged at the inside of this combustion chamber 10, so in the past only receive the heat of shell 15 radiation of combustion chamber 10 and the heat supply water inflow pipe 25 of preheating can strengthen heat transfer area and absorbs heat at a side joint.
In addition, owing to adopt copper pipe 30a in the inside of above-mentioned heat-exchange tube 30, its outside aluminum tube 30b that adopts, form the state of dual structure, on the outer peripheral face of above-mentioned aluminum tube 30b, form heat absorption fin 35 by the roll forming mode, so needn't require to use in addition as before the hard solder process, so procedure of processing is simplified, qualification rate improves.
In the superincumbent description, above-mentioned combustion chamber 10 provides as general gas fired-boiler by example and figure, owing to the objective of the invention is in the combustion chamber 10 inside, form heat supply water inflow pipe 25, on the shell 15 of combustion chamber 10, be provided with heat insulating member 45, improve heat conduction efficiency, so obviously can be suitable for seeking all boilers of such purpose.
That is, the invention is not restricted to aforementioned such scheme,, can understand easily, in the scope that does not break away from design of the present invention and field, can make amendment and change according to multiple mode for those of ordinary skill in the art.
Effect of the present invention
As mentioned above, if adopt the combustion chamber of gas fired-boiler of the present invention, supplying hot water is flowed into And the supplying hot water inflow pipe that flows through is not arranged at the outside of combustion chamber, and is arranged at its inside, in combustion Burn on the shell of chamber, heat insulating member is set, strengthen thus heat transfer area, prevent that heat is discharged to the outside And wasting situation obviously can absorb more heat in the inside of combustion chamber, forms little The device of type, compact conformation. In addition, the present invention when forming heat-exchange tube, the material of heat-exchange tube Material is formed by dual structure, and wherein, aluminum tube is adopted in the outside of this pipe, and adopt the inside of this pipe simultaneously With the good copper pipe (copper pipe) of pyroconductivity, or at the shape that is formed whole heat-exchange tube by copper pipe Attitude forms thermofin by the roll forming mode, this thermofin be arranged at heat-exchange tube outside On the side face, thus, the handling ease of heat-exchange tube can with economized form production, make life simultaneously Production capacity power improves, extremely useful effective invention.
