The invention has the advantages of simple structure, high voltage endurance and remarkable heat-exchanging efficiency.
Description
One, technical field
The present invention relates to a kind of improved volume-type condensing gas furnace heat exchanger.
Two, technical background
Existing condensing gas furnace heat exchanger adopts fin split type mostly, and promptly heat exchanger and condenser be for dividing body structure up and down, the manufacturing process complexity, and the cost height, through the fin conduction, the heat conduction approach is long, the near ideal of heat conduction efficiency.Volume-type condensing combustion gas heat-exchanger rig is also arranged, but its flat heat exchange pipe broad all, resistance to pressure is bad.
Existing condensing gas furnace mostly is infrared ray sealing combustion system again, no matter is finned or positive displacement, and its combustion chamber inwall does not all have the infrared ray selectivity to absorb the top layer, and this has just lost the absorption of radiant energy.Therefore, also just lost certain thermal efficiency.
The objective of the invention is to overcome the problems referred to above, a kind of volume-type condensing gas furnace heat exchanger is provided, by being coated with the combustion chamber inwall of infrared ray selectivity absorption plated film, infrared energy is fully absorbed, absorb sensible heat and latent heat through narrower, super flat flat heat exchange pipe again, thereby effectively raise heat exchange efficiency and voltage endurance capability, domestic water water heat exchange coil adopts corrugated pipe coil simultaneously, therefore the heat exchange area than the common coil pipe of equal length increases about one times, simple in structure, work simplification, thereby when improving heat exchanger effectiveness, reduce cost.
Three, summary of the invention
The object of the present invention is achieved like this: volume-type condensing gas furnace heat exchanger, be by stainless steel cylinder, the combustion chamber, the infrared ray selectivity absorbs plated film, flat heat exchange pipe, low head, domestic water water heat exchange corrugated pipe coil, life cold water water supply connector, life hot water effluent's joint, the heating hot water out splice going splice, heating low temperature backwater joint, life is formed with water outlet thermal insulation gum sleeve and water capacity chamber.
For further realizing purpose of the present invention, at least 30 compositions of flat heat exchange pipe.
For further realizing purpose of the present invention, the width of flat heat exchange pipe should be in 20-30mm, and thickness is between 6～7mm.
For further realizing purpose of the present invention, the physical wavelength of combustion chamber inwall selectivity absorption Coating Materials should be between 1.3～5 microns.
For further realizing purpose of the present invention, the degree of depth of combustion chamber should be between 65-95mm.
At least enclose outer wall of combustion chamber around 5 circles for further realizing purpose of the present invention, domestic water water heat exchange corrugated pipe coil.
Compared with the prior art the present invention has following distinguishing feature and good effect: the present invention is heat exchange, the condensation integrative-structure, adopt the combustion chamber in last upside down, and be coated with the infrared ray selectivity at the combustion chamber inwall and absorb plated film, improved the assimilation effect of infrared energy, several stainless steel flat tubes have been welded on the lower arcuate surface of (dash have several flat holes) of going to the bottom in the combustion chamber, the cambered surface of (having dashed several flat holes are arranged) on the low head of stainless steel flat tube and urceolus bottom is welded and is connected, constitute top-down flue gas heat exchange nest of tubes, carrying out the transition to latent heat gradually from the sensible heat absorption absorbs, the condensation assimilation effect is obvious, between combustion chamber skin and cylindrical shell, be wound with a few domestic water water heat exchange corrugated stainless steel tubings, bellows two is drawn by the heat-exchanger rig lower end, and under the corrugated pipe coil hot water outlet pipe, draw (in the volume water cavity) section and install the thermal insulation gum sleeve additional, thereby can not influence the condensation segment operating mode, owing to adopt the heat exchange of corrugated pipe coil water water, in limited length, increased heat exchange area, reduced cost, it is simple to coil technology.
Four, description of drawings
Below in conjunction with accompanying drawing and example the present invention is described in further detail.
Figure one is a kind of structural representation of the present invention.
Figure two is schematic cross-section of the present invention.
Figure three is partial structurtes schematic diagram of the present invention.
Five, specific embodiments
Embodiment one, volume-type condensing gas furnace heat exchanger, with reference to Fig. 1, Fig. 2, Fig. 3, top in cylindrical shell 1 is provided with combustion chamber 2, the inwall of combustion chamber 2 is coated with the infrared ray selectivity and absorbs plated film 3, on the lower arcuate surface of combustion chamber 2 (dashed several flat holes are arranged), flat heat exchange pipe 4 has been welded, flat tube 4 passes water capacity chamber 12, its lower end is welded with the arcwall face of low head 5 (dashed several flat holes are arranged) and is connected, form the heat exchange flue, domestic water water heat exchange corrugated pipe coil 6 also is housed between combustion chamber 2 and cylindrical shell 1, the two ends of corrugated pipe coil 6 cause life under the inwall of staving 1 and also are connected with cold water water supply connector 7 with hot water effluent's joint 8 and life, in addition with the bellows (in the water capacity chamber) that is connected with hot water effluent's joint 8 of life under draw and overlap a thermal insulation gum sleeve 11 on the straight section, heating hot water out splice going splice 9 and heating low temperature backwater joint 10 are housed two ends respectively up and down at cylindrical shell, above structure member is that the corrosion-resistant stainless steel material is welded and screw connects to form except that heat insulation gum sleeve 11.
Embodiment two, volume-type condensing gas furnace heat exchanger, with reference to Fig. 1, Fig. 2, Fig. 3, on the basis of embodiment one, the degree of depth of combustion chamber 2 should be between 65～95mm, present embodiment adopts the 95mm degree of depth, the Material Physics wavelength present embodiment that combustion chamber inwall infrared ray selectivity absorbs plated film 3 adopts between the 1.3-5 micron, and flat heat exchange pipe 4 present embodiments have adopted 54 of wide 30mm * thick 6.5mm flat tube, and other and embodiment one are identical.
