Abstract
The utility model relates to a heat exchanger for gas heater, including heat exchanger fin, heat transfer shell, water pipe, the water pipe is fixed on heat transfer shell, and the heat exchanger fin is fixed on the water pipe, characterized by heat exchanger fin and heat transfer shell make by copper steel combined material. Because the utility model discloses a copper steel combined material makes heat exchanger fin, heat transfer shell, and the copper product of its outward appearance parcel can satisfy the requirement of heat exchange performance, and inside steel base plate has replaced the copper product, makes the use amount of copper product obviously descend, has reduced heat exchanger's manufacturing cost effectively. And through experimental verification, the utility model discloses can satisfy the requirement of gas heater to heat exchange performance.
Description
Technical field
The utility model relates to heat exchanger, especially a kind of heat exchanger that is used for gas heater.
Background technology
In the prior art, the heat exchanger fin in the heat exchanger of gas heater, heat exchange shell, water pipe are normally by adopting copper material soldering manufacturing to form, to satisfy the performance of its heat exchange.Yet Copper Product in China is rare, and international copper valency rises steadily, and causes the heat exchanger material cost of gas heater constantly to increase.For overcoming the too high defective of gas heater cost, need the gas heater material therefor is improved so that can reduce the production cost of heat exchanger under the prerequisite that guarantees heat exchange performance.
Summary of the invention
The purpose of this utility model is to overcome the too high defective of prior art heat exchanger material cost, and providing a kind of can satisfy on the basis of heat exchange performance, effectively reduces the heat exchanger that is used for gas heater of cost.
Realize that the technical scheme that the utility model purpose is adopted is: a kind of heat exchanger that is used for gas heater, comprise heat exchanger fin, heat exchange shell, water pipe, water pipe is fixed on the heat exchange shell, and heat exchanger fin is fixed on the water pipe, it is characterized in that described heat exchanger fin is to be made by copper-steel composite material.
Further, the heat exchange shell in the technique scheme is also made by copper-steel composite material.
Above-mentioned copper-steel composite material is for being substrate with steel, and it is wrapped with copper material.
The heat exchanger fin of described heat exchanger, heat exchange shell, water pipe are to be welded together by soldering.
Improve its service life for making copper-steel composite material be difficult for being corroded, terne metal or braze surface preservative treatment are soaked in exchange backing, heat exchange shell and water pipe surface.
The utility model with the beneficial effect that the prior art contrast is produced is:
Because the utility model adopts copper-steel composite material to make heat exchanger fin, heat exchange shell, the copper material of its appearance parcel can satisfy the requirement of heat exchange performance, and inner steel substrate has substituted copper material, and the use amount of copper material is obviously descended, and has reduced the production cost of heat exchanger effectively.And by verification experimental verification, the utility model can satisfy the requirement of gas heater to heat exchange performance.
Description of drawings
Fig. 1 is the structural representation of embodiment of the present utility model;
Fig. 2 is the structural representation of the employed copper-steel composite material of the utility model.
Omitted among the figure and the irrelevant miscellaneous part of the utility model design main points.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and embodiment.
With reference to figure 1, Fig. 2, the gas heater of present embodiment all adopts the copper-steel composite material manufacturing with heat-exchanging fin for heat-exchanger 1, heat exchange shell 2, and used copper-steel composite material is for being substrate with steel 5, and it is wrapped with copper material 6, as shown in Figure 2.Add man-hour, heat exchanger fin 1, water pipe 3 connect into a heat exchanger assemblies by the soldering welding manner, again heat exchange shell 2 is connected by the copper brazing welding manner with water pipe 3, form a heat exchanger, and exchange backing 1, heat exchange shell 2, water pipe 3 surfaces soak terne metal or braze surface preservative treatment, make it be difficult for being corroded and improve service life.
The utility model adopts copper-steel composite material to make heat exchanger fin 1, heat exchange shell 2, the copper material 6 of its appearance parcel can satisfy the requirement of heat exchange performance, and inner steel 5 substrates have substituted copper material of the prior art, the use amount of copper material is obviously descended, reduced the production cost of heat exchanger effectively.And by verification experimental verification, the utility model can satisfy the requirement of gas heater to heat exchange performance.
