Abstract
The utility model relates to a heat exchange coil in a condensing gas heater. A multi-connected multi-layer heat exchange coil is formed by a plurality of spiral coils in parallel and adopts the multi-connected multi-layer structure of multi-connected arrangement in parallel in the horizontal direction and multi-layer arrangement in the vertical direction; the water inlet ends of the multi-connected multi-layer heat exchange coil are integrated into a water inlet water separator and are connected with water inlet pipes ; and the water outlet ends thereof are also integrated into a water outlet water separator and are connected with water outlet pipes. The utility model abandons a sheet heat exchanger structure, saves timber, and simplifies the structure; the three-dimensional space inside a vice heat exchanger is used fully, so that the structure is more compact; and compared with the vice heat exchanger of the sheet heat exchanger, the thermal efficiency of the vice heat exchanger of the multi-connected multi-layer heat exchange coil can be improved by two to three percentage points.
Description
Technical field
The utility model relates to domestic gas-fired water heater, particularly the heat exchange coil in the 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 a kind of multi-joint multilayer heat exchange coil and replaces original sheet heat exchanger fin, described multi-joint multilayer heat exchange coil, and the heat exchange efficiency height, structure is simple relatively, and materials are less, and cost is lower.
A kind of multi-joint multilayer heat exchange coil of the present utility model, it is characterized in that: described heat exchange coil is arranged in parallel by many spiral coils, and forming has the multi-joint multi-joint sandwich construction that has multilayer to arrange side by side, in vertical direction in the horizontal direction.
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.
Advantage of the present utility model is:
1. given up the sheet heat exchanger structure, saved and used material, simplified the structure.
2. multi-joint sandwich construction coil pipe is fully utilized the solid space of secondary heat exchanger inside, make the more compact structure of secondary heat exchanger, the thermal efficiency is higher, by test, compare with the secondary heat exchanger of general employing sheet heat exchanger, adopt the auxiliary heat exchanger thermal efficiency of multi-joint multilayer coil pipe of the present utility model can improve 2～3 percentage points.Realize further energy savings, reduced the target of toxic emission.
Description of drawings
Fig. 1 is a sheet heat exchanger structure schematic diagram of the prior art;
Fig. 1 is the structural representation of multi-joint multilayer heat exchange coil of the present utility model.
Among the figure: 1 coil pipe, 2 water inlet pipes, 3 water inlet water knockout drums, 4 water outlet water knockout drums, 5 outlet pipes.
The specific embodiment
Now the utility model is described in further detail in conjunction with an embodiment and accompanying drawing 2.
Multi-joint multilayer heat exchange coil of the present utility model is arranged in parallel twist by many coil pipes 1, and forming has the multi-joint multi-joint sandwich construction that has multilayer to arrange side by side, in vertical direction in the horizontal direction.
The water inlet end of described multi-joint multilayer heat exchange coil 1 is concentrated to a water inlet water knockout drum 3 and is connected with water inlet pipe 2, and its water side also is concentrated to a water outlet water knockout drum 4 and is connected with outlet pipe 5.
Figure 2 illustrates 33 layers of coil pipe that are arranged in parallel and form by 3 spiral coils.
