Description
Technical field
The utility model is related to heat exchanger technology fields, and in particular to a kind of condensed heat exchanger.
Background technology
Condensed type combustion gas water heater is compared with general gas water heater, more level-one condensing heat exchangers, by absorbing high temperature
Flue gas and preheating cold water.So as to improve thermal conversion efficiency, combustion gas is saved.
Condensed heat exchanger includes combustion chamber and waterway, and high-temperature flue gas is generated to water flowing by burning in combustion chamber
Water in road is heated.Since combustion chamber is lower further away from burning point temperature, the water in waterway also cannot be by uniform
Heating, there are the efficiency of heating surface it is low the problem of.
To solve the above problems, the Chinese utility model patent that notification number is CN204084860U discloses a kind of condensing
The exhaust heat recovery structure of burnt gas wall hanging furnace, technical solution are mainly in the direction that burning chamber inner sidewall is reduced along ignition temperature
Closeness gradually increased heating column is provided with, increases the utilization rate to high-temperature flue gas, to enhance the efficiency of heating surface.The structure is one
Determine to be conducive in degree the water thermally equivalent in waterway, have the advantages that enhance the efficiency of heating surface, but there is also shortcomings.Heat conduction
Column is provided only on to add and not extended into waterway in combustion chamber, and water body can only pass through the cavity wall that burns and absorb heat, heat transfer efficiency
It is not high.And columned heating column is relatively thick, is unfavorable for the conduction of heat, so as to the absorptivity of heat in flue gas not
Height, it is whole so that the efficiency of heating surface of heat exchanger is not high.
Utility model content
In view of the above-mentioned problems, the utility model is intended to provide a kind of condensed heat exchanger so that it can preferably utilize
High-temperature flue gas heats cold water, improves the efficiency of heating surface, and used technical solution is：
A kind of condensed heat exchanger including heat exchange housing and is arranged on the inlet and outlet to exchange heat on housing,
The heat exchange housing includes inner housing and outer housing, water flowing layer is formed between the inner housing and outer housing, the inner housing encloses
Around formation combustion chamber.The combustion chamber inner housing is provided with the heat for absorbing flue gas and heat, and it is conducted to the more of water flowing layer
Group heating column.
The heating column is staggered, and the heating column is set as polygon prism shape along the layering of flow of flue gas direction,
Side wall is frosting.Exhaust gases passes are formed between the side wall of the heating column of adjacent layer, the heating column is through described interior
Housing, both ends are located in combustion chamber and water flowing layer respectively；The water barrier for increasing water route is provided in the water flowing layer.
Through the above technical solutions, heating column is set as polygon prism shape and layering is staggered, relative to cylindric entirety
Heating surface area bigger is more advantageous to quickly absorbing heat transfer to water flowing layer, the water body in water flowing layer is heated.Heating column
