Description
Technical field
The utility model relates to domestic gas-fired water heater, particularly condensed type combustion gas water heater.
Background technology
Existing pot-type boiler generally has only a heat exchanger, but a heat exchanger is difficult to fully absorb latent heat in the flue gas, and exhaust gas temperature is very high, so the thermal efficiency is not high.Condensing type water heater is to increase a secondary heat exchanger again on the basis of existing pot-type boiler above main heat exchanger, in normal working conditions, flue gas is during by secondary heat exchanger, steam in the flue gas is by partial condensation, and the latent heat that discharges, and absorbed by secondary heat exchanger, with the efficient of further raising water heater.
The structure of general secondary heat exchanger is similar to main heat exchanger, adopt slice structure, as shown in Figure 1, its heat exchanger is made up of the sheet heat exchanger fin 102 and the single coil 101 of many dense arrangement, after the flue gas that is ejected by main heat exchanger entered secondary heat exchanger, the latent heat in the flue gas was absorbed by heat exchanger fin by the gap between heat exchanger fin and the coil pipe time, the water in the heat(ing) coil, water at low temperature flows into from water inlet, and high-temperature water flows out from delivery port.The secondary heat exchanger of this form, complex structure, the material of use is more, and cost is higher, and the thermal efficiency awaits further to improve.
Summary of the invention
The purpose of this utility model is to propose the secondary heat exchanger of a kind of multi-joint multilayer heat exchange coil formula, and described secondary heat exchanger adopts multi-joint multilayer heat exchange coil to make heat exchanger, and structure is simple relatively, and materials are less, and cost is lower, and the thermal efficiency is also higher.
The secondary heat exchanger of a kind of multi-joint multilayer heat exchange coil formula of the present utility model, comprise a housing, be provided with smoke air inlet in described housing one side, the housing top side is provided with the waste gas escape pipe, in described housing inner chamber, be provided with heat exchange coil, the housing bottom side is provided with the condensed water outlet pipe, and described heat exchange coil is arranged twist side by side by many coil pipes, and forming has the multi-joint multi-joint sandwich construction that multilayer is closely arranged side by side, in vertical direction in the horizontal direction.
In described housing, multi-joint multilayer heat exchange coil above be provided with a flue gas guide diaphragm.This flue gas guide diaphragm direction offside on air inlet extends, and along the downward bending of heat exchange coil, is lower than the lower edge of air inlet to its lower edge, and the housing inner chamber is separated into heat exchanging chamber and exhaust passage two parts.
The water inlet end of described multi-joint multilayer heat exchange coil is concentrated to a water inlet water knockout drum and is connected with water inlet pipe, and its water side also is concentrated to a water outlet water knockout drum and is connected with outlet pipe.
Further, in described housing multi-joint multilayer heat exchange coil above and forwards extend and be provided with a flue gas guide diaphragm.The minimum point of the place ahead extension of described flue gas guide diaphragm is lower than the minimum point of the air inlet on the housing.
Further, the upside at described housing 2 disposes temperature sensor or temperature relay.
The advantage of secondary heat exchanger of the present utility model is:
1. improved the heat exchange efficiency of secondary heat exchanger:
Water inlet is adopted by one the tunnel and is become multichannel, and water outlet is two to become one tunnel structure by multichannel, and the heat that makes water to absorb in the flue gas more fully to be produced has improved the thermal efficiency; Sandwich construction has then further utilized the inner space of whole secondary heat exchanger, makes full use of the heat in the flue gas as much as possible; Set up the flue gas guide diaphragm, path and the time of staying of flue gas in secondary heat exchanger further extended, heat exchange is more abundant, thereby reaches higher heat exchange efficiency.Survey secondary heat exchanger of the present utility model and compare with the secondary heat exchanger of the chip of Fig. 1, the thermal efficiency can improve 2-3 percentage point, reaches energy savings, reduces the effect of toxic emission.
2. increased the security of water heater:
It is acid that the condensed water that secondary heat exchanger is separated out is, as stopping up when the condensed water discharge outlet 11 of housing bottom side or during impeded drainage, being acid condensed water has corrosiveness to equipment, the service life of meeting shortening heat hydrophone.But because the position (referring to the 3a line among Fig. 3 and Fig. 5) of air inlet of the present utility model is higher than the minimum point (referring to the 9a line among Fig. 3 and Fig. 5) of flue gas guide diaphragm the place ahead extension, so when the height of condensed water rises to the 9a line, because gas channel is blocked, controller in the water heater will be controlled water heater and quit work, and can prevent effectively that condensed water from pouring in down a chimney; Equally, when case temperature surpassed normal design temperature, the temperature sensor or the temperature relay 10 that are configured in the housing upside just can send signal, by the controller in the water heater water heater are quit work, thereby guaranteed the security of water heater.
3. simplify the structure, saved material, reduced cost.
