Description
Technical field
The present invention relates to a kind of heat exchanger, particularly relate to a kind of condensing heat exchanger.
Background technology
Heat exchanger has been widely used for industry and civil area at present, and heat exchange mode is with traditional tubulation fin
Pattern is main.This traditional tubulation finned heat exchanger not only structure and complex process, manufacture and material becomes
This higher (the red copper material of costliness must be used), but also need to be arranged on below heat exchanger burner.
The flue gas that burner combustion produces is from bottom to top through heat exchanger, and water flows through tubulation and absorbs flue gas by fin
In heat and heat up, and flue-gas temperature heat transfer process decline, the thermal efficiency of heat exchanger only has about 85%.
For gas fired-boiler, due to gas fuel combustion process, to there is not solid, liquid fuel incomplete
The heat loss that the phenomenon of burning, ash and chemistry are imperfect combustion is almost nil, the mainly smoke evacuation of its heat loss
Heat loss, account for about the 80% of whole heat loss.Want to improve further the thermal efficiency of gas fired-boiler,
It is accomplished by reducing the temperature of smoke evacuation.
Further, for gas fired-boiler, owing to the combustion gas major part of gas fired-boiler is hydrocarbon, i.e. contain a large amount of
Protium, combustion process formed steam with flue gas discharge.When exhaust gas temperature is less than flue gas dew point temperature
Time, the steam in flue gas can be condensed into condensed water and drip downwards, having a strong impact on and be arranged on below heat exchanger
The normal work of burner.
Being limited by its structure just because of traditional heat exchangers, the exhaust gas temperature not only resulting in gas fired-boiler cannot
Less than 150 DEG C, and cause the latent heat of vaporization of steam to make full use of, cause the wave in vain of the energy
Take.
As can be seen here, the temperature effectively reducing smoke evacuation is to improve heat exchanger with making full use of steam gasification latent heat
Two key points of the thermal efficiency, are also simultaneously industry technical barriers urgently to be resolved hurrily.
Summary of the invention
It is an object of the invention to the deficiency existed for prior art described above, it is provided that a kind of rational in infrastructure,

Office, uses this structure, and when high-temperature flue gas passes through the heat exchanger tube of third layer genesis analysis, heat exchanger tube can be by cigarette
Edema caused by disorder of QI is slit into parallel longitudinal airflow layer.Parallel longitudinal airflow layer wants changing by second layer cross direction profiles
During heat pipe, horizontally-parallel airflow layer will be converted into.During this conversion, high-temperature flue gas is forced
Surface along the heat exchanger tube of second layer cross direction profiles circles and produces strong forced heat-exchanging.
In like manner, during the heat exchanger tube of horizontally-parallel airflow layer ground floor to be passed through genesis analysis, will be converted into
Parallel longitudinal airflow layer, forced heat-exchanging can occur again again.
Owing to the arrangement mode of adjacent two layers heat exchanger tube is vertical arrangement, high-temperature flue gas is by each layer of heat exchange
Guan Douhui reappears the process of forced heat-exchanging, and the effect of forced heat-exchanging is better than the effect of traditional heat convection,
Therefore the thermal efficiency of heat exchanger can be improved further.
(4) present invention is equipped with shell passage in forward and backward, the side, left and right of heat exchanger body so that shell
Heat exchanger high-temperature region can completely be surrounded by the water in passage, and this shell structure is possible not only to substantially reduce heat
Amount is scattered and disappeared, but also can significantly reduce the operating temperature of heat exchanger, is effectively improved the working environment of heat exchanger.
The normal working temperature using the heat exchanger of this structure is generally not more than leaving water temperature.
(5) heat exchanger of the present invention has the high thermal efficiency, even with the aluminium alloy that thermal conductivity is poor
Material, also can reach the heat-conducting effect being satisfied with very much, can substitute the expensive red copper that traditional heat exchangers uses
Material, not only contributes to reduce the material cost of heat exchanger, and is also beneficial to popularizing of heat exchanger.
