Abstract
The utility model provides an improved heat-exchange device, particularly a heating gas boiler heat-exchange device, mainly composed of two heating pipes which respectively make reciprocating rotation from bottom to top as multilayer circulation pipes, besides, a water inlet and a water outlet are communicated with the return pipe and the water outlet pipe through a three-way pipe. The utility model has the advantages of high thermal efficiency, high rate of hot water production, and energy-saving.
Description
The utility model relates to a kind of improved heat-exchange device, particularly a kind of heat-exchange device of heating gas furnace.
At present, as the gas heater of heating, mainly formed by burner, temperature controller and heat-exchange device.Its heat-exchange device is by the return pipe that is wrapped in the chamber wall bottom, and outlet pipe, heating tube, combustion chamber and the heat transmission fin that is set on the heating tube are formed, and its heating tube is back and forth to be circled round on a horizontal plane by a copper pipe to be the individual layer circulation line.The thermal efficiency of this kind structure water heater is low, and generally all below 75%, the hot water productive rate of output is lower, and energy waste is bigger, and therefore, such water heater is unsuitable for as supplying dim equipment.
The purpose of this invention is to provide a kind of improved heat-exchange device, make it to have the higher thermal efficiency and hot water productive rate, it is changed on the general gas water heater, can be transformed into and be suitable for heating gas furnace.
The utility model is realized by following scheme:
The heat-exchange device of the utility model is made up of the return pipe that is wrapped in the chamber wall bottom, outlet pipe, heating tube, combustion chamber and the heat transmission fin that is set on the heating tube.For the efficiency of heating surface that improves recirculated water is provided with two heating tubes, and from bottom to top back and forth circles round respectively and be the multilayer circulation line, the water inlet end of heating tube is communicated with return pipe by three-way pipe, and the water side of heating tube is communicated with outlet pipe by three-way pipe.The circulation line axis of adjacent upper and lower interlayer is not on same vertical plane.
Adopt the heat-exchange device of said structure, improved the thermal efficiency, hot water productive rate greatly under equal energy resource consumption condition, its thermal efficiency can reach 93%, improves 5%-10 than general gas water heater.
The embodiment that provides below in conjunction with accompanying drawing is described in further detail the structure of the utility model.
Fig. 1 is the front view of the utility model.
Fig. 2 is that the A-A shown in Fig. 1 is to cutaway view.
Fig. 3 is that the I-I shown in Fig. 1 is to cutaway view.
Fig. 4 is that the II-II shown in Fig. 1 is to cutaway view.
Fig. 5 is that the III-III shown in Fig. 1 is to cutaway view.
Referring to figs. 1 through Fig. 5, the heat exchanger of the utility model is made up of the return pipe (1) that is wrapped in wall bottom, combustion chamber (7), outlet pipe (4), heating tube (2), (3) and the heat transmission fin (8) that is set on the heating tube, from bottom to top back and forth circle round respectively and are three layers of circulation line in heating tube (2), (3), the water inlet end of heating tube (2), (3) is communicated with return pipe (1) by three-way pipe (5), and the water side of heating tube (2), (3) is communicated with outlet pipe (4) by three-way pipe (6).The circulation line axis of adjacent upper and lower interlayer is not on same vertical plane.Return pipe (1), heating tube (2), (3), outlet pipe (4), three-way pipe (5), (6) and heat transmission fin (8) are all manufactured with surperficial wicking copper pipe.
During work, cold water enters heating tube (2), (3) from return pipe (1), and circulation heating back is flowed out from outlet pipe (4) and flowed to radiator.
Present embodiment employing caliber is that the copper pipe of Φ 18 is manufactured, through measuring hot water productive rate is 9L/min, the thermal efficiency reaches 90.3%, when injecting 25 ℃ of water, only promptly reach 40 ℃, when return water temperature during up to 70 ℃ with 45 seconds leaving water temperatures, exhaust gas temperature is 110 ℃, and the water heater return water temperature that uses at present is when reaching 50 ℃, and its exhaust gas temperature is up to 170 ℃-180 ℃, national standard requirement head and shoulders above.
Claims (3)
1. highly effective heating gas furnace heat-exchange device, formed by the return pipe (1) that is wrapped in wall bottom, combustion chamber (7), outlet pipe (4), heating tube and the heat transmission fin (8) that is set on the heating tube, it is characterized in that: be provided with two heating tubes (2), (3), from bottom to top back and forth circle round respectively and are the multilayer circulation line in heating tube (2), (3), the water inlet end of heating tube (2), (3) is communicated with return pipe (1) by three-way pipe (5), and the water side of heating tube (2), (3) is communicated with outlet pipe (4) by three-way pipe (6).
