The heat exchanger of the existing gas water heater has low heat efficiency and high energy consumption. The heat exchanger of the gas water heater (1) comprises a water service pipe (2) and a fin (3) arranged on an outer pipe wall; the utility model is characterized in that the water service pipe (2) is of an elliptical pipe or a ribbon shape flat pipe, the fin (3) can be punched with burbling holes (4) and is provided with a temperature measuring element and an explosion proof safety device so as to continuously supply the water with stable temperature.
Description
The utility model relates to a kind of gas heater.
The heat exchanger of existing gas heater is that the fin that circular water service pipe and pipe outer wall are equipped with is formed by the cross section, and the thermal efficiency is low, the energy consumption height.
The purpose of this utility model provides a kind of thermal efficiency height that has, the gas heater of the heat exchanger that energy consumption is low.
The fin (3) that the heat exchanger (1) that the purpose of the present utility model is achieved in that this gas heater is installed by water service pipe (2) and pipe outer wall is formed, and it is characterized in that water service pipe (2) is elliptical tube or banded flat tube.Fin (3) is installed on the outer wall of water service pipe (2), can stamp out flow-disturbing hole (4) on the fin (3).
Water service pipe (2) is the metal tube that is provided with in horizontal direction, when water service pipe (2) when being elliptical tube, the long axis of ellipse direction is consistent with the airflow direction of burning gases, fin (3) is a sheet metal, have and the identical hole of water service pipe (2) cross sectional shape, and, be installed on the outer wall of water service pipe (2).In heat exchanger (1), water service pipe (2) can adopt the individual layer set-up mode, also can adopt the multilayer set-up mode, and when adopting the individual layer set-up mode, the water service pipe of elliptical tube (2) is assembled into continuous serpentine.In this case, except that union elbow, all the other straight-tube portions are parallel to each other.Two terminations after the assembling are communicated with (as shown in Figure 1) with inlet channel and outlet conduit respectively.When adopting the multilayer set-up mode, the water service pipe of elliptical tube (2) is assembled into continuous serpentine in every layer, again upper strata and lower floor's water service pipe (2) successively are together in series, and make its two terminations be communicated with (as shown in Figure 2) with inlet channel and outlet conduit respectively.
When water service pipe (2) when being banded flat tube, the length direction in banded flat tube cross section is consistent with the airflow direction of burning gases, and in heat exchanger (1), water service pipe (2) can adopt the individual layer set-up mode, also can adopt the multilayer set-up mode.When adopting the individual layer set-up mode, banded flat tube is made continuous serpentine, in this case, except that bent tube section, all the other straight-tube portions are parallel to each other, and fin (3) is a sheet metal, make continuous " Z " shape, be installed on the pipe outer wall between the flat tube that is parallel to each other.Two terminations after the assembling are communicated with (as shown in Figure 3) with inlet channel and outlet conduit respectively.When adopting the multilayer set-up mode, the water service pipe (2) of banded flat tube is made continuous serpentine in every layer, and the water service pipe (2) with upper strata and lower floor successively is together in series again, and its two terminations are communicated with inlet channel and outlet conduit respectively.
In order further to improve the thermal efficiency, can on fin (3), stamp out flow-disturbing hole (4), flow-disturbing hole (4) hole wall projection, Open Side Down.
The other parts of the present utility model gas heater, same as the prior art as combustion chamber (5), shell (6) etc.
The present utility model and prior art are compared has following advantage: water service pipe (2) resistance in red-hot air-flow of the heat exchanger in the present utility model gas heater (1) is little, the afterbody eddy current loss is little, under same pipe inner flow passage cross section, heat transfer perimeter is long, and heat exchange area is big.Under identical heat exchanger appearance and size, the water service pipe that the present utility model adopted (2) can be arranged closelyr, and the heat output of heat exchanger unit volume is significantly increased.Stamp out flow-disturbing hole (4) on the fin (3), can destroy the flow boundary of red-hot air-flow, augmentation of heat transfer, therefore, and the present utility model gas heater thermal efficiency height, energy consumption is low, simultaneously, can also load onto temperature element.Explosion-proof security personnel's annex etc. is used for hot water without interruption or boiling water.
