Abstract
The utility model relates to a heat exchanger of a gas water heater. The heat exchanger comprises a combustion chamber, a water pipe and heat exchange pieces, wherein one end of the water pipe is a cold water inlet end, one end of the water pipe is a hot water outlet end, the heat exchange pieces are arranged on the top in the combustion chamber, and the hot water outlet end stretches out of the top of the combustion chamber; and the particular points of the heat exchanger are that the cold water inlet end of the water pipe is arranged on the lower part of the combustion chamber and is in a fence shape, and the water pipe is enwound on the external surface of the middle of the height direction of the combustion chamber. As the structure is adopted, the cold water inlet end of the water pipe firstly utilizes middle flame on the bottom of the combustion chamber to preheat, then, the top of the combustion chamber utilizes the heat exchange pieces to heat, the heat energy is fully utilized, and the heat efficiency is improved.
Description
Technical field
The utility model relates to a kind of device of gas heater, especially a kind of heat exchanger of gas heater.
Background technology
Present prior art; A kind of heat exchanger of gas heater comprises combustion chamber, water pipe and heat exchanging fin, and an end of water pipe is that cold water water inlet end, an end are hot water effluent's end; Heat exchanging fin is arranged on the top in the combustion chamber, and hot water effluent's end stretches out at the top of combustion chamber; The cold water water inlet end of water pipe is begun to twine by the bottom of combustion chamber outer surface, and water pipe back and forth passes heat exchanging fin at the top of combustion chamber.Existing problems are: existing problems are: the thermal efficiency, heat exchanging fin is away from flame.
Summary of the invention
The purpose of the utility model is: a kind of heat exchanger of gas heater is provided, and it can effectively utilize middle part flame, and cold water is carried out preheating, in the top of combustion chamber heating, has improved the thermal efficiency.
The utility model is achieved in that a kind of heat exchanger of gas heater; Comprise combustion chamber, water pipe and heat exchanging fin; One end of water pipe is that cold water water inlet end, an end are hot water effluent's end, and heat exchanging fin is arranged on the top in the combustion chamber, and hot water effluent's end stretches out at the top of combustion chamber; Its special character is: the bottom of cold water water inlet end in the combustion chamber of said water pipe is paliform, and water pipe twines on the outer surface at the middle part of combustion chamber short transverse.
The heat exchanger of described a kind of gas heater, its special character is: cold water water inlet end type of being bent into of said water pipe falls " U " shape and passes the left and right sidewall of combustion chamber.
The heat exchanger of a kind of gas heater of the utility model; Owing to adopt such structure, the cold water water inlet end of water pipe at first utilizes the flame at middle part to carry out preheating in the bottom of combustion chamber, utilizes heat exchanging fin to heat at top of combustion chamber then; Make full use of heat energy, improved the thermal efficiency.
Description of drawings
Fig. 1 is the front view of the utility model.
Fig. 2 is A-A view of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1; A kind of heat exchanger of gas heater comprises combustion chamber 1, water pipe 2 and heat exchanging fin 3, and an end of water pipe 2 is that cold water water inlet end 21, an end hold 22 for the hot water effluent; Heat exchanging fin 3 is arranged on the top in the combustion chamber 1, the hot water effluent hold 22 in the combustion chamber 1 top stretch out; The bottom of cold water water inlet end 21 in combustion chamber 1 of said water pipe 2 is paliform, and water pipe 2 twines on the outer surface at the middle part of combustion chamber 1 short transverse.The condensation of paliform portion reduces the carbon deposit of sulfide on heat exchanging fin 3.
Cold water water inlet end 21 types of being bent into of said water pipe 2 fall " U " shape 23 and pass the left and right sidewall of combustion chamber 1.
Above-described only is the preferential embodiment of the utility model.Should be pointed out that for the person of ordinary skill of the art under the situation that does not break away from the utility model principle, can also make some improvement and modification, this also is regarded as the protection domain of the utility model.
Claims (2)
