Description
Technical field
The present invention relates to a kind of gas heater heat-exchanger rig, particularly to a kind of heat-exchanger rig of condensing type water heater.
Background technology
The heat exchanger of condensed type combustion gas water heater typically adopts two heat exchangers, carries out based on the heat exchanger of first time heat exchange
Heat exchanger, most heat exchange completes in this heat exchanger, the structure of this heat exchanger and the heat exchanger structure of common water heater
Identical.The heat exchanger carrying out second heat exchange is time heat exchanger, mainly cements out the heat of water vapour in flue gas, here
During can produce a large amount of condensed waters, this condensed water has certain acidity, and therefore this heat exchanger must be able to corrosion-resistant, Er Qieleng
Solidifying water must collect discharge water heater.
The secondary heat exchanger of existing general condensed type combustion gas water heater, the fin of its finned tube is all using copper sheet system
Make, described fin surface is coated with corrosion-resistant coating, and its corrosion-resistant coating can not effectively prevent acid condensate water to copper sheet in a long time
The corrosion of heat exchanger, therefore many producers begin with rustless steel and make secondary heat exchanger, with condensate water-proof to secondary heat exchanger
Corrosion.But rustless steel is poor compared with copper exchange capability of heat it is therefore desirable to substantial amounts of rustless steel to increase heat exchange area to improve the thermal efficiency,
Increased cost；Simultaneously in order to improve the thermal efficiency, flue gas must keep Long contact time to carry out more heat exchange with rustless steel, but its
Considerably increase the resistance of fume emission, have impact on the combustion conditions of water heater；In addition, the condensed water that secondary heat exchange produces meets row
When putting smooth, water heater can not quit work, and can overflow water spilage tray to a heat exchanger and burner, may damage water heater
Internals.
Content of the invention
It is an object of the invention to the above-mentioned deficiency in the presence of overcoming prior art, provide a kind of simple and compact for structure,
Heat exchange area is big, and heat exchanger can be allowed to be automatically stopped the heat exchange of the condensed type combustion gas water heater of work when condensed water elimination is not smooth
Device.
In order to realize foregoing invention purpose, the invention provides technical scheme below：
