Abstract

The utility model discloses an improved structure of a heat exchanger for a gas water heater, which comprises a cold water inlet pipe, a coiled pipe, a hot water outlet pipe and a heat exchanger body. A part of the coiled pipe penetrates through a portion which is provided with heating fins and arranged on the heat exchanger body, the remaining coiled pipe is wound on the outer portion of the heat exchanger body, the cold water inlet pipe is communicated with a port, which is close to the heating fins of the heat exchanger body, of the coiled pipe, and the hot water outlet pipe is communicated with another port, which is far away from the heating fins of the heat exchanger body, of the coiled pipe. The improved structure realizes smaller temperature difference between the heat exchanger body and the coiled pipe on the outer portion of the heat exchanger body, flue gas generated by combustion cannot be suddenly cooled when passing the position during exhaustion, flue exhaustion temperature is increased, accordingly, condensate water on the inner wall of the heat exchanger is reduced, and the service life of the water heater is prolonged.

Description

Gas heater heat exchanger structure-improved
Technical field
The utility model relates to a kind of gas heater heat exchanger, particularly a kind of gas heater heat exchanger structure-improved.
Background technology
At present, use in the heat exchanger at gas heater commonly used, cold water inlet is connected with the end of coil pipe away from heat exchanger body heating fin, the hot water outlet pipe is connected with the other end of coil pipe near heat exchanger body heating fin, cold water is entered the coil pipe that heats an end of fin away from heat exchanger body by cold water inlet, coil pipe along the outside that is set around heat exchanger body flow to the other end of coil pipe near heat exchanger body heating fin again, flows out from the hot water outlet pipe at last.
Use in the heat exchanger at gas heater commonly used, because cold water just is heated coil pipe when heat exchanger body is provided with the part coil pipe that the position of heating fin passes flowing through, so enter the outside that is set around heat exchanger body coil pipe all be cold water, the temperature difference that is set around the coil pipe of heat exchanger body outside and heat exchanger body is bigger, this kind structure exhaust gas temperature is lower, cause the saturated steam air pressure in the flue gas on the low side easily, separate out condensed water at the heat exchanger position easily, and the generation of condensed water exists great harm to gas heater, shortens its service life.
The service life of general gas heater is about 8 years, if condensed water in use usually appears in gas heater heat exchanger main body section, can cause the minimizing in its service life, this is because the condensed water that produces can mix with NOx in the flue gas that burning produces etc., produce the heat exchanger body of acidic materials corrosion gas heater, reduce the service life of gas heater; On the other hand, because the high temperature fin is original just relative less with the spacing of high temperature fin, the condensed water of generation is adsorbed between the fin easily, adds the colloid residue that fuel gas buring is incomplete and produce, formed carbon distribution, be adsorbed on around the fin, the spacing between obstruction and minimizing fin, then can produce a large amount of imperfect combustions this moment, CO and NOx content can significantly rise in the flue gas, cause environmental pollution easily,, then can have a strong impact on the normal use of gas heater if stop up seriously.
Summary of the invention
In order to overcome above-mentioned defective, the utility model provides a kind of gas heater heat exchanger structure-improved, and this gas heater can improve exhaust gas temperature with the heat exchanger structure-improved, reduces the generation of heat exchanger body inwall condensed water.
The utility model for the technical scheme that solves its technical problem and adopt is: a kind of gas heater heat exchanger structure-improved, comprise cold water inlet, coil pipe, hot water outlet pipe and heat exchanger body, the part coil pipe passes from the position that heat exchanger body is provided with the heating fin, all the other coil pipes are set around the outside of heat exchanger body, cold water inlet is connected with the port of coil pipe near heat exchanger body heating fin, cold water is heated when the coil pipe of an end of the close heat exchanger body heating fin of flowing through, and the hot water outlet pipe is connected with the another port of coil pipe away from heat exchanger body heating fin.
As further improvement of the utility model, described heat exchanger body is arranged on gas heater inside, and heat exchanger body one end is provided with the flue gas access port that produces flue gas when receiving burning, and the other end is provided with the fume emission mouth.
The beneficial effects of the utility model are: this gas heater heat exchanger structure-improved, cold water inlet is connected with the end of coil pipe near heat exchanger body heating fin, make that the temperature difference of the coil pipe of heat exchanger body outside and heat exchanger body is less, when discharging, can not cooled off suddenly the flue gas that burning produces in this position, exhaust gas temperature is improved, thereby reduce the generation of heat exchanger inwall condensed water, prolong the service life of water heater.

The specific embodiment
Embodiment: a kind of gas heater heat exchanger structure-improved, comprise cold water inlet 1, coil pipe, hot water outlet pipe 3 and heat exchanger body 2, the part coil pipe passes from the position that heat exchanger body 2 is provided with the heating fin, all the other coil pipes are set around the outside of heat exchanger body 2, cold water inlet 1 is connected with the port of coil pipe near heat exchanger body 2 heating fins, cold water is heated when the coil pipe of an end of the close heat exchanger body 2 heating fins of flowing through, and hot water outlet pipe 3 is connected with the another port of coil pipe away from heat exchanger body 2 heating fins.
Described heat exchanger body 2 is arranged on gas heater inside, and heat exchanger body 2 one ends are provided with the flue gas access port that produces flue gas when receiving burning, and the other end is provided with the fume emission mouth.
This gas heater with the structure improved course of work of heat exchanger is: cold water is directly entered the coil pipe that heats an end of fins near heat exchanger body 2 by cold water inlet 1, cold water heats by coil pipe herein, coil pipe along the outside that is set around heat exchanger body 2 flow to the other end of coil pipe away from heat exchanger body 2 heating fins again, flows out from hot water outlet pipe 3 at last.Since cold water flow through from heat exchanger body 2 be provided with the heating fin the position pass the part coil pipe time coil pipe, be heated, so enter the outside that is set around heat exchanger body 2 coil pipe all be hot water, the temperature difference that is set around the coil pipe of heat exchanger body 2 outsides and heat exchanger body is less, when discharging, can not cooled off suddenly the flue gas that burning produces in this position, its exhaust gas temperature is improved, thereby reduces the generation of heat exchanger inwall condensed water.
