The content of utility model:
The purpose of this utility model provides a kind of simple in structure, the condensed heat exchanger that heat exchange efficiency is high.
The utility model is achieved in that
The utility model condensed heat exchanger, the cylindrical shell 13 that has endothermic tube 7 coilings or axially-aligned to constitute in the horizontal cylindrical outer casing 8, the inwall of the outer wall of cylindrical shell 13 and shell 8 is gapped, the two ends of endothermic tube 7 are connected with water out adapter 2 with water supply connector 1 respectively, exhaust opening 9 is arranged on the shell 8, under condensation-water drain 12 is arranged, for the combustion chamber of gas burner is set, at least one end of shell 8 has burner installing hole 15 in the cylindrical shell 13.
Endothermic tube 7 is some straight tubes, along shell 8 axially and inwall be arranged in one deck formation cylindrical shell 13 at least, the bottom of fixed disk 6 and back fixed disk 10 was tightly connected with it before the two ends of cylindrical shell 13 were passed respectively, before, rear fixed plate is an annular, its axial cross section is a flute profile, respectively with front shroud 4 with before back shroud 11 is tightly connected, back hydroecium, before, there is water-stop sheet 5 that it is divided into the plurality of sub hydroecium in the back hydroecium, the front and back hydroecium is communicated with by endothermic tube 7, a sub-hydroecium of front water chamber is communicated with water supply connector 1, another sub-hydroecium is communicated with water out adapter 2, and the burner installing hole is arranged on the front shroud 4, and back shroud 11 is a closure plate.
The cross section of endothermic tube 7 is oval or circular.
Endothermic tube 7 is that a coil pipe coiled coil constitutes cylindrical shell 13, shell 8 one ends seal and have water out adapter 2 to be communicated with water outlet cavity 14, water outlet cavity 14 is communicated with an end of endothermic tube 7, the other end of shell 8 has installing hole 15 and water inlet cavity 14, water inlet cavity 16 is communicated with the water supply connector 1 and endothermic tube 7 other ends, some burner mounting screws 3 around the installing hole 15.
Gap between the inwall of the outer wall of cylindrical shell 13 and shell 8 is at least 10mm.
The utility model is simple in structure, easy to manufacture, and is easy to install, with low cost, the heat exchange efficiency height.
The utility model utilizes the water cooling flue gas that temperature is lower in the endothermic tube, flue-gas temperature is reduced, the cylinder body outer wall condensation that water vapour constitutes at endothermic tube in the flue gas, condensed water is discharged by condensate drain outlet, and the flue gas that is cooled is discharged by exhaust opening, realizes that obvious heat of smoke discharges and water recovery latent heat discharges, and in the endothermic tube water heat absorption and be heated, realize energy recovery, improve boiler thermal output, can improve rate of heat exchange more than 8%.Pernicious gases such as CO in the flue gas and NOX are reduced greatly.Endothermic tube is compared with existing heat exchanger tube, and heat conductivility has improved more than 2 times.

The specific embodiment:
Embodiment 1:
Wall hung gas boiler constitutes heat absorption cylindrical tube 13 with condensed heat exchanger by endothermic tube 7 coiled coils, the endothermic tube two ends are connected with water inlet cavity 16 with water outlet cavity 14 respectively, endothermic tube 7, water outlet cavity 14 and water inlet cavity 16 are positioned at shell 8, the outer wall of cylindrical shell 13 and shell 8 inwalls have the 10-20mm gap, water out adapter 2 is connected with water inlet cavity 16 with water outlet cavity 14 respectively with water supply connector 1, shell has burner installing hole 15, burner is installed in the cylindrical shell 13 by this installing hole, the shell upper end connects exhaust opening 9, and the lower end connects condensation-water drain 12.
Embodiment 2:
Some straight endothermic tubes 7 are arranged in one deck or two-layer formation cylindrical shell 13, and being arranged in one deck available cross-section is oval-shaped endothermic tube, are arranged in two-layer available cross-section and are circular endothermic tube.Bottom surface and its welding of fixed disk 6 and back fixed disk 10 before the cylindrical shell two ends are passed respectively.Forward and backward fixed head is an annular, its axial cross section is a flute profile, form forward and backward hydroecium with annular front shroud 4 and 11 welding of circular back shroud respectively, there are four water-stop sheets 5 to be divided into four sub-hydroeciums in the front water chamber, one of them sub-hydroecium is communicated with water supply connector 1, and another sub-hydroecium is communicated with water out adapter 2.Hole in the middle of the front shroud 4 is an installing hole 15, and its periphery is evenly equipped with 6 burner mounting screws 3.There are three water-stop sheets 5 to be divided into 3 sub-hydroeciums in the back hydroecium.Exhaust opening 9 is arranged on the shell 8, condensation-water drain 12 is arranged down.
