Abstract
The utility model provides a condensing type gas heat exchanger, which comprises a housing, a combustor arranged in the housing, and a main heat exchanger arranged at the upper part of the combustor and provided with main heat collecting sheets. The top of the housing is provided with a flue gas outlet. The condensing type gas heat exchanger is characterized in that the top of the main heat exchanger is provided with a secondary heat exchanger with secondary heat collecting sheets. Heat-collecting tubes provided with a water inlet and a hot water outlet sequentially penetrate through the housing, the secondary heat collecting sheets and the main heat collecting sheets. A thermal insulation plate supported on the housing is arranged between the main heat exchanger and the secondary heat exchanger. The condensing type gas heat exchanger is high in thermal efficiency and reduces the consumption of copper material. The condensing type gas heat exchanger is also convenient to machine, energy-saving and environment-friendly.
Description
Technical field:
The utility model is relevant with gas heat exchanger, and is special relevant with the condensed type combustion gas heat exchanger.
Background technology:
Heat exchanger generally is divided into six types: plain edition heat exchanger, environment-friendly type heat exchanger, single channel wall hanging furnace heat exchanger, binary channels wall hanging furnace heat exchanger, plate type heat exchanger and condensed heat exchanger.Present domestic plain edition heat exchanger is to soak slicker solder with red copper (being fine copper T1-T3) at last through processing to form, and it is 55% that existing market is occupied ratio; The environment-friendly type heat exchanger is to form through the last soldering of processing with oxygen-free copper (being fine copper TP1-TP3 or TU1-TU3), and it is 40% that existing market is occupied ratio.Copper material is non-renewable metal, and its present price is very high, and it also is the armament goods and materials, and various countries' homogeneous phase is hoarded, and holds at high price, now still about 60,000/ton.It is 5% that the hot water exchanger existing market of split condensing is occupied ratio.Traditional condensing type water heater is by two heat exchangers separately, through flue flue gas is entered condensing heat exchanger again and carries out heat exchange.
The utility model content:
The purpose of the utility model is in order to overcome above deficiency, to provide a kind of thermal efficiency high, can reducing the copper material consumption, and is easy to process, the condensed type combustion gas heat exchanger of energy-conserving and environment-protective.
The purpose of the utility model realizes like this:
The utility model condensed type combustion gas heat exchanger comprises the housing that contains the top outlet flue, is positioned at the burner of housing; Be positioned at the main heat exchanger that contains main heat collecting sheet on burner top; It is characterized in that being positioned in the housing main heat exchanger top has the secondary heat exchanger that contains secondary heat collecting sheet, and the thermal-collecting tube that contains water inlet and hot water outlet is through on housing and secondary heat collecting sheet and the main heat collecting sheet successively, and the thermal insulation board that is supported on the housing is arranged between main heat exchanger and secondary heat exchanger; Cold water and hot water constitute connected component; Release heat under fuel gas buring, through the heat collecting sheet heat absorption, the heat of heat collecting sheet is passed to thermal-collecting tube water is heated; Cold water at first gets into secondary heat exchanger through thermal-collecting tube, behind smoke pre-heating, is recycled to main heat exchanger and heats.
On the above-mentioned thermal insulation board condensation water channel is arranged; The place is easy to generate condensed water at secondary heat exchanger; Let flue gas by the marginal flow of thermal insulation board to secondary heat exchanger; The condensed water of collecting can be discharged into and reach discharge in PH6.5-8.5 o'clock after a processor is handled, because it is a slightly acidic water, does not handle also can directly be discharged in the sewage pipe.
In the utility model when work,, by burner combustion, flue gas carries out the exchange of heat for the first time through main heat exchanger, through thermal insulation board stop the back flue gas through the slit flow between housing and the thermal insulation board to secondary heat exchanger, the petticoat pipe on outlet flue again, flue gas is just discharged.Cold water is introduced into secondary heat exchanger through thermal-collecting tube, carries out preliminary heat exchange with secondary heat collecting sheet, flows to main heat exchanger again and main heat collecting sheet carries out heat exchange, and the water of outflow supplies people's domestic water.
The utility model thermal efficiency is high, and the low copper material consumption that can disappear is easy to process, energy-conserving and environment-protective.
Description of drawings:
Fig. 1 is the utility model structural representation.
Fig. 2 is the thermal insulation board structural representation.
Fig. 3 is the utility model fundamental diagram.
The specific embodiment:
Referring to Fig. 1～Fig. 3; Present embodiment condensed type combustion gas heat exchanger; Comprise the housing 2 that contains top outlet flue 1; Be positioned at the burner 3 of housing, be positioned at the main heat exchanger 5 of containing of burner top of main heat collecting sheet 4, being positioned at the main heat exchanger top in the housing has the secondary heat exchanger 7 that contains secondary heat collecting sheet 6.The thermal-collecting tube 10 that contains water inlet 8 and hot water outlet 9 is through on housing and secondary heat collecting sheet and the main heat collecting sheet successively.The thermal insulation board 11 that is supported on the housing is arranged between main heat exchanger and condensing heat exchanger.Condensation water channel 12 is arranged on the thermal insulation board.
Claims (2)
1. condensed type combustion gas heat exchanger; Comprise the housing that contains the top outlet flue; Be positioned at the burner of housing, being positioned at burner top has the main heat exchanger that contains main heat collecting sheet, and it is characterized in that being positioned in the housing main heat exchanger top has the secondary heat exchanger that contains secondary heat collecting sheet; The thermal-collecting tube that contains water inlet and hot water outlet is through on housing and secondary heat collecting sheet and the main heat collecting sheet successively, and the thermal insulation board that is supported on the housing is arranged between main heat exchanger and secondary heat exchanger.
2. condensed type combustion gas heat exchanger as claimed in claim 1 is characterized in that condensation water channel is arranged on the thermal insulation board.
