However, in the conventional heater, water is supplied in an area adjacent to the burner installed at the lower part of the heater, and thus the lower end of the water tank is low temperature and maintains high temperature toward the upper end, so that the heat exchange efficiency is lowered, resulting in a problem due to heat loss. .

In addition, since heat exchange is performed by convection in one chamber space, the heat transfer area cannot be maximized, resulting in reduced combustion efficiency and excessive fuel loss, and delayed hot water generation due to late heat exchange. There was a problem.

In addition, the waste gas combusted in the combustor is exhausted without being recycled after being exchanged with the water chamber only in the flue, thereby resulting in an uneconomical use.

On the other hand, the tube 18 is provided with a baffle 86 for increasing turbulence and agitation of the combustion gas.

On the other hand, Figure 3 is a perspective view showing the flow rate of the water chamber 20 and the associative 18 is formed in a single form, one independent association 18 is disposed in the water chamber 20 so that the fluid of the water chamber 20 is lower As a result, the gas in the tube 18 has a structure flowing upward.

In addition, the heat exchange fin 74 is formed by tearing the upper portion of the circular tube into several strands as shown in FIGS. 7A, 7B, and 7C attached to the outer surface of the tube 18, and then bending only the upper portion to the outside.

On the other hand, the water chamber 20 and the associating 18 to be used in various forms by applying a gas to the corresponding fluid heating device not limited to the fluid.

8A and 8B, square and round pipes 94 and 96 may be formed to overlap each other in a concentric manner and may be configured as an independent indoor ventilation heat exchanger 90 and 92.

According to the present invention having the above configuration, the water supplied through the water supply port 22 formed in the upper portion of the heat exchanger 30 or 30a in the shape of a circle or a square forms a turbulent flow from the top to the bottom into the water chamber 20. do.

Filled water in the water chamber 20 is the combustion of the combustion through the combustion member 60 by the combustion operation of the burner 16 provided at the lower end of the heat exchanger 30 is injected into the upper portion of the heat exchanger (30) It is discharged | emitted to the exhaust port 14 through the several connection pipe | channel 18 formed in the.

That is, as shown in FIG. 3, the gas of the plumbing 18 rises to the top to exchange heat with the water chamber 20, and the water in the water chamber 20 descends to form heat exchange, thereby generating hot water.

The generated hot water is discharged through the discharge port 24 attached to the bottom of the heat exchanger 30 and stored in the hot water storage tank 84 or used as heating or hot water.

3 is an embodiment in which one tube 18 and the water chamber 20 correspond to the liquid or gas in the water chamber to exchange heat with the heat of the tube 18 to obtain hot water or hot wind.

That is, the fluid or gas that descends from the water chamber 20 is heat-exchanged with the combustion gas rising through the pipe 18 provided in the center of the water chamber 20.

The present invention experiments with the generation of hot water, placing the tube 18 in the water chamber 20 of 7 meters in length (height), 23 ° C water is injected into the chamber and lowered by injecting water, 82 ° C below the tube 18 When the heat exchange was performed by raising the hot water of the water, the generated hot water warmed to the lower part of the water chamber 20 became 62 ° C, and the cooled hot water discharged to the top of the pipe 18 became 52 ° C.

As a result, the heat exchange efficiency becomes high according to the length (height) of the water chamber 20 and the tube 18, thereby maximizing the thermal efficiency.

On the other hand, the water supply port 22 and the discharge port 24 has pumps 80 and 82 to induce forced water supply and forced drainage to improve the flow of water in the water chamber 20.

In this heat exchange process, the water flow can be efficiently moved from the upper side to the lower side by the plurality of diaphragms 26 and 26a arranged in a plurality of states arranged in the water chamber 20.

On the other hand, by installing a heat exchange ring 78 on the outer surface of the tube 18 can be improved heat exchange efficiency in the water chamber (20).

That is, as shown in FIG. 7A, when the upper part of the pipe end pipe is generally torn into multiple strands, only the upper part of the pipe end pipe is bent to the outside, thereby obtaining a shape as shown in FIG. 7B, and a plurality of heat exchange fins 76 are formed on the upper part as shown in FIG. 7C. When one or more heat exchange rings 78 are coupled to the tube 18, a plurality of heat exchange fins 76 are provided in the water chamber 20 to increase the heat transfer area of the heat exchange, thereby increasing heat exchange efficiency.

If it is used as (92), it is possible to obtain a pleasant indoor environment by the ventilation action.

On the other hand, in the present invention, by using the gas in the water chamber 20 without limiting only the liquid to the allowable region, a wide range and preferable use is also used for using a gas such as a dryer as a medium.

As described in detail above, the present invention maximizes the heat transfer area by stacking a plurality of diaphragms at the bottom to form a flow of water in the chamber of the heat exchanger from the top to the bottom, and the associated combustion gas flows from the bottom to the top. The lower end of the tank maintains a high temperature and gradually forms a low temperature at the top, thereby enabling heat exchange while water supplied from the top flows downward, thereby increasing heat exchange efficiency, and forming a three-way air ejection zone on the combustion member to supply combustion air. By making the stable and good to improve the combustion efficiency, the heat exchange efficiency of the heat exchanger is improved and thus there is an effect that can achieve an economical boiler operation.
