Description
Technical field
The utility model relates to a kind of Wiper blade type heat exchanger tube, also relates to a kind of Wiper blade type condensed heat exchanger that comprises Wiper blade type heat exchanger tube.
Background technology
Wall-hung boiler is the abbreviation of burnt gas wall hanging furnace, burnt gas wall hanging furnace is using natural gas, artificial coal gas or liquefied gas as fuel, fuel is exported through burner, after burning Indoor Combustion, by heat exchanger, by heat absorption, the recirculated water in heating system is when by way of heat exchanger, through heating in reciprocating mode, thereby constantly heat is exported to building, for building provides thermal source.
Wall-hung boiler has two large classes at present: air suspended type wall-hung boiler and condensing type wall-mounted furnace.Air suspended type wall-hung boiler adopts ordinary burner and semi-open combustion chambers burn natural gas, in optimized situation, operate at full capacity and can reach 93% the thermal efficiency (disregarding the latent heat that steam contains), along with reducing the thermal efficiency, also reduces gradually load, during to 30% load, the thermal efficiency is about 75%, and in its exhaust oxynitrides and carbon monoxide content all higher, can only reach national grade III Standard.Product after combustion of natural gas is carbon dioxide and water, and water is to emit with the form of steam, contains a large amount of latent heat in steam.Condensed water wall-hung boiler is the method that adopts premixed burning, make flue gas force to pass through heat exchanger, greatly reduce flue-gas temperature, steam transforming in flue gas becomes condensed water elimination to go out, can make like this thermal efficiency at full capacity time, reach 103%, when 30% load, reach 108% (establishing the whole calorific values of natural gas is 113%), and the fume emission of condensing furnace is lower than the half of country-level standard.
Heat exchanger is the core component of condensing type wall-mounted furnace.Household central heating wall-hung boiler often adopts tube coil type heat exchanger and cast aluminum heat exchanger at present.Because spatial limitation, some producers adopt cylindrical shape burner, have used the heat exchanger of upright cylindrical shape serpentine coil formula, and the power of this heat exchanger is larger, and volume is just huger, also there is no in the market 35kw and above Domestic wall stove thereof.Whole world consumption maximum is the horizontal condensate and heat exchanger of Stainless Steel Coil that Italian Giannoni produces at present, its advantage is that material corrosion resistance is the strongest, cost is low, but horizontal coiled-tube heat exchanger has the feature of exhaust problem, because water (flow) direction is not from low to high, but around helix from high to low more from low to high, each circle has peak, gas can stop at peak, and because stainless steel tube internal diameter is little, water resistance is large, in practice, heating water flow all can be less than design load, cause the temperature difference large, operating mode is very unstable.The vertical condensation heat exchanger of Italy Valmex, adopt the structure of similar air suspended type boiler main heat exchanger as the internal structure of condensation chamber, by outside fin in Al pipe butt welding as heat sink, due to all-aluminium construction, under soldering condition, welding temperature can only be lower than the fusion temperature of aluminium, not prison welding is leaned on, and after the time is long, can loosening cause heat conduction bad.
