The specific embodiment
Referring to accompanying drawing 1, accompanying drawing 2, accompanying drawing 3, accompanying drawing 4, accompanying drawing 5, accompanying drawing 6, accompanying drawing 7, shown in the accompanying drawing 8, present embodiment comprises housing 6, the heat exchanger main body, smoke evacuation cover plate 4, gas approach 8, housing seal bar 9, smoke evacuation cover plate 4 is provided with exhanst gas outlet 5, housing 6 comprises inlet opening and apopore, the heat exchanger main body comprises inlet water divider 1, water outlet water collector 2, set of heat exchange tubes 3, inlet water divider 1, the centre that water outlet water collector 2 is made for the stainless steel material of nickel postwelding is the cuboid of cavity, the outside is provided with the water pipe that is communicated with cavity, the inboard is provided with the through hole corresponding with set of heat exchange tubes 3, the water inlet pipe of inlet water divider 1 is by the inlet opening of housing 6 and outside pipeline connection, the outlet pipe of water outlet water collector 2 is by the apopore of housing 6 and outside pipeline connection, set of heat exchange tubes 3 is comprised of the continuous U corrugated stainless steel tubing more than two, one-body molded and adjacent two bellowss of each bellows are Heterogeneous Permutation side by side, one end of every corrugated stainless steel tubing is welded on the through hole of inlet water divider 1, and the other end is welded on the through hole of water outlet water collector 2.The periphery of housing 6, housing seal bar 9, smoke evacuation cover plate 4 is respectively equipped with corresponding screwed hole, smoke evacuation cover plate 4 is placed in the top of housing 6, the centre installs the housing seal bar 9 that a silicon rubber or acrylonitrile-butadiene rubber are made additional, then with screw three's locking is located, good sealing effect guarantees that flue gas is outside through whole discharge machines behind the heat exchanger.
The heat exchanger main body is simple with respect to fin type heat exchanger structure, can simplify manufacturing process, enhances productivity.In addition, because Copper Product in China is rare, original copper finned heat exchanger cost is higher, corrosion-resistant, and set of heat exchange tubes 3 of the present utility model adopts stainless steel material, can effectively reduce material cost, improves the corrosion resistance of heat exchanger.The continuous U corrugated stainless steel tubing group of Heterogeneous Permutation can effectively increase heat exchange area, improve heat exchange efficiency side by side, and compact conformation, space availability ratio are high.
Further, present embodiment also comprises the smoke deflector 7 that stainless steel or high-temperature resistance plastice (such as anti-combustion PC, PPC) are made, smoke deflector 7 is installed in housing 6 middle parts and is positioned at the smoke air inlet place, because set of heat exchange tubes 3 Heterogeneous Permutations, therefore smoke deflector 7 is provided with the tongue corresponding with set of heat exchange tubes 3, U-shaped bending degree according to set of heat exchange tubes 3, tongue can also can be semicircle for square, if set of heat exchange tubes 3 dislocation are fewer and feweri, also can make water wave type or even straight plate, present embodiment is square tongue.Can exchange heat pipe heat plays certain fixation to smoke deflector 7 on the one hand, on the other hand, can allow flue gas discharge behind a circle along heat exchanger again, and the fume side resistance is little, flue-gas temperature can be reduced to condensation point, takes full advantage of the heat of high-temperature flue gas.
