Abstract

The utility model discloses a condensation heat exchanger for gas water heater. The utility model is characterized in that the heat exchanger mainly consists of a stainless heat transfer tube and a bracket; the stainless heat transfer tube is assembled and fixed through the bracket; the external surface of the stainless heat transfer tube is provided with a three-dimensional petal fin; and the internal surface of the tube is provided with a trench spiral groove. The utility model adopts the stainless tube and makes the installation and fixing through the stainless bracket. The utility model with excellent corrosion resistance and heat exchange effect can fully utilize the heat produced by the gas to pre-heat the water, effectively enhance the efficiency of the water heater, reduce the discharge of harmful gases and achieve high environmental efficiency, so as to provide a novel energy-saving and healthy gas water heater.

Description

A kind of condensed type combustion gas water heater heat exchanger
Technical field
The utility model relates to the condensed type combustion gas water heater field, more particularly relates to a kind of heat exchanger of condensed type combustion gas water heater.
Background technology
The tradition gas heater is equipped with related devices such as combustion chamber, heat exchanger usually, utilize heat exchanger to absorb the heat that combustion gas produced, pass to by the flow through cold water of heat exchanger of water inlet pipe, water temperature raises after heat exchange, hot water is discharged from outlet pipe, realize the function of flow heated water, the high-temperature flue gas that burning produces is extracted out outdoor by blower fan through smoke chamber.Because flue gas is taken away sizable a part of heat, causes the thermal efficiency of water heater limited, heat utilization ratio is difficult to promote.People set up a cover flue gas condensing system on the heat exchanger basis of traditional gas heater for this reason, the combustion chamber is by the combustion gas heating heat exchanger, produce high-temperature flue gas, be drawn into smoke chamber through blower fan, cold water enters condenser from water inlet pipe and absorbs the high-temperature flue gas heat preheating current that produce the combustion chamber, and cooled flue gas is separated out condensed water and inorganic salt simultaneously, condensed water arrives by drainpipe discharges behind the neutralization chamber outdoorly, and condensed flue gas is discharged outdoor by gas outlet, smoke chamber top.Through heat exchanger, hot water is discharged through outlet pipe after exchange heat through the current of preheating, and condensed type combustion gas water heater has utilized the flue gas heat flow heated water, and heat utilization efficiency is greatly improved.And the condensed heat exchanger of prior art all is to adopt finned copper pipe heat exchanger, in actual application, the exhanst gas outlet temperature that contains acid water steam is up to 250~270 ℃, heavy corrosion condenser fin and pipeline, using a period of time the condenser heat exchange efficiency to occur reduces, situations such as corrosion of piping perforation, cause water heater to run well, in order to solve the problem of high temperature corrosion, usually apply corrosion-inhibiting coating at the fin outer surface of matrix, but this scheme exists the heat exchanger long term reliability can be difficult to guarantee to influence with corrosion-inhibiting coating the drawback of heat exchanger overall thermal efficient.
Summary of the invention
The purpose of this utility model is exactly that provide for the deficiency that solves prior art a kind of not only has excellent corrosion resistance and heat exchange effect, and effectively reduces the condensed type combustion gas water heater heat exchanger of discharge of harmful gases.
The utility model is to adopt following technical solution to realize above-mentioned purpose: a kind of condensed type combustion gas water heater heat exchanger, it is characterized in that it is mainly reached to prop up by stainless steel heat-transfer pipe and is configured to, and stainless steel heat-transfer pipe installs and fixes by support.
As further specifying of such scheme, described stainless steel heat-transfer pipe road outer surface is provided with three-dimensional petal-shaped fin, and inner surface of pipeline is provided with ditch shape spiral cell body.
Described support adopts stainless steel material, and inside and outside surface, stainless steel heat-transfer pipe road is respectively equipped with screw thread or fin.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is: the utility model adopted and disposed the heat exchanger of being made of high heat exchange efficiency stainless steel heat-transfer pipe and support in gas heater, pipeline external surface at described heat exchanger is provided with three-dimensional petal-shaped fin, inner surface is provided with shallow ridges shape spiral cell body, make it to possess high heat exchange efficiency and excellent decay resistance rust prevention system, make it to have simultaneously high heat exchange efficiency and excellent decay resistance, thereby avoid heat exchanger to be subjected to the erosion of high-temperature flue gas, keep water heater overall thermal exchange efficiency and service life, can make full use of the heat preheating current that combustion gas produces, effectively improve water-heater efficiency, reduce discharge of harmful gases simultaneously, realize environment-friendly high-efficiency, the gas fired water heater of energy-saving health is provided for people.

The specific embodiment
As Fig. 1, Fig. 2 and shown in Figure 3, a kind of condensed type combustion gas water heater heat exchanger of the utility model, it is arranged on water heater at fume emission mouth place, mainly constitute by stainless steel heat-transfer pipe 1 and support 2, be used to absorb high-temperature flue gas heat preheating current, reduced waste heat losses, the thermal efficiency of elevator system, stainless steel heat-transfer pipe 1 installs and fixes by support 2, employing 304 or 316L material stainless steel tube, before heat exchanger assembling to stainless steel tube in, outer surface carries out heat conduction reinforced forming processes, make it to possess high heat exchange efficiency and excellent decay resistance rust prevention system, pipeline matrix 3 outer surfaces are provided with three-dimensional petal-shaped fin 4 or screw thread or fin, can reduce thin condensate film thickness, reduce and be detained the angle, promote the quick disengaging of condensate liquid from tube surface; Inner surface of pipeline is provided with shallow ridges shape spiral cell body or screw thread or fin, helps the thickness in attenuate boundary layer, the turbulence that excites the boundary layer, the separation that promotes the boundary layer, formation secondary stream.
In the use, water heater is equipped with the condenser system of being made up of stainless steel heat-transfer pipe and support at fume emission mouth place, absorb high-temperature flue gas heat preheating current, after the condenser cooling, N, S oxide contained in the flue gas are separated out in cooling, drain with condensed water, thereby reduced discharge of harmful gases, alleviated pollution environment.
The utility model is not limited to the foregoing description; described pipeline outer surface of matrix is except being provided with three-dimensional petal-shaped fin or screw thread or fin; can also adopt other frame mode to make the quick disengaging of condensate liquid from tube surface; be not limited to scope of the present utility model; those skilled in the art also can do numerous modifications and variations; under the spirit that does not break away from utility model, all in the claimed scope of the utility model.
