Abstract
Disclosed is an aluminum /aluminum alloy heat exchanger for gas water heater, comprising heat exchanging shell, water pipe fixed on the heat exchanging shell, heat exchanging fins fixed on the water pipe, technically characterized in that the heat exchanging fin, water pipe and heat exchanging shell are made of aluminum/aluminum alloy material. The invention has properties in effective cost-saving in heat exchanger based on heat exchanging performance that is satisfied.
Description
Technical field:
The present invention relates to a kind of gas heater aluminium/Al-alloy heat exchanger.
Background technology:
In the prior art, heat-exchange fin, water pipe, heat exchange shell adopt copper material soldering manufacturing usually in the heat exchanger of gas heater.The copper material of China is rare, and international copper valency rises steadily, and causes the material cost of heat exchanger to increase.For overcoming existing gas heater material cost defective, gas heater is developed with aluminium/Al-alloy heat exchanger.
Summary of the invention:
Technical problem to be solved by this invention provides a kind of gas heater aluminium/Al-alloy heat exchanger, and it can reduce cost effectively satisfying on the basis of heat exchange performance.
The technical scheme that the present invention solves its technical problem employing is: it comprises heat-exchange fin, water pipe, heat exchange shell, water pipe is fixed on the heat exchange shell, heat-exchange fin is fixed on the water pipe, and described heat-exchange fin, water pipe, heat exchange shell are by aluminium/aluminum alloy materials manufacturing.
Described heat-exchange fin, water pipe, heat exchange shell surface are provided with the overlay film layer.
Described water pipe and heat exchange shell, heat-exchange fin and water pipe weld with soldering.
Described overlay film layer is an electrodeposited coating.
Described overlay film layer is the coat of paint.
The present invention compares the beneficial effect that is produced with prior art:
1,, and, can satisfy heat exchange performance, so it can reduce cost effectively satisfying on the basis of heat exchange performance by verification experimental verification because the present invention adopts aluminium/aluminum alloy materials to make heat-exchange fin, water pipe, heat exchange shell.
Description of drawings:
Fig. 1 is a structural representation of the present invention.
The specific embodiment:
Referring to accompanying drawing 1, the heat-exchange fin 1 of gas heater, water pipe 2, heat exchange shell 3 adopt aluminium/aluminum alloy materials manufacturing, heat-exchange fin 1 connects into a gas heat exchanger assembly with water pipe 2 by soldering or other connected mode, heat exchange shell 3 connects into a gas heat exchanger with water pipe 2, heat exchanger assemblies by soldering or other connected mode, and to the processing of electroplating or paint of heat-exchange fin 1, water pipe 2, heat exchange shell 3 surfaces, produce overlay film layers such as the electrodeposited coating or the coat of paint, make it be difficult for being improved service life by aqueous corrosion.
