The heat exchanger is characterized in that the water heat exchange passage is arranged in the wall of the casing; one part of the heat exchange unit is arranged in the heat exchange chamber, and the other part is arranged in the combustion chamber; and the casing and the heat exchange unit are integrally cast and formed by aluminum alloy material. The utility model can effectively enhance the contact area between the water heat exchange passage and the casing, and then further enhance heat exchange efficiency, structure strength and the like.
Description
Technical field: the utility model relates to the condensing heat exchanger of a kind of heat exchanger of gas heater, particularly a kind of condensed type combustion gas water heater.
Background technology: in the prior art, the heat exchanger of gas heater adopts formations such as housing, heat exchange unit, water heat exchanger channels usually, heat exchange unit is arranged in the interior Heat Room of housing, the water heat exchanger channels is separately positioned on the outer wall of housing and in the Heat Room in the housing, and water heat exchanger channels and housing are by being welded to connect, cause to exist water heat exchanger channels and housing contact area less, limited the defectives such as heat exchange efficiency of heat exchanger.For overcoming these defectives, the heat exchanger of gas heater is developed.
Summary of the invention: technical problem to be solved in the utility model is the heat exchanger that a kind of gas heater will be provided, and it can improve the contact area of water heat exchanger channels and housing effectively, and then improves the heat exchange efficiency and the structural strength of heat exchanger.
The technical scheme that its technical problem that solves the utility model adopts is: it comprises housing, heat exchange unit, water heat exchanger channels, the inner chamber of housing is provided with combustion chamber and Heat Room, be provided with the water heat exchanger channels in the wall of described housing, the part of described heat exchange unit is arranged in the Heat Room, another part is arranged in the combustion chamber, and housing and heat exchange unit are the aluminum alloy materials integral casting forming.
The cross section of described water heat exchanger channels is circular.
The cross section of described water heat exchanger channels is oval.
The cross section of described water heat exchanger channels is square.
Heat exchanger fin in the described heat exchange unit is a cylinder.
Heat exchanger fin in the described heat exchange unit is a square cylinder.
Heat exchanger fin in the described heat exchange unit is a triangle cylinder.
Heat exchanger fin in the described heat exchange unit is the waveform cylinder.
The inwall of described water heat exchanger channels is provided with spoiler.
The utility model is compared the beneficial effect that is produced with background technology:
1, owing to is provided with the water heat exchanger channels in the wall of the utility model employing housing, the part of described heat exchange unit is arranged in the Heat Room, another part is arranged in the combustion chamber, housing and heat exchange unit are the structure of aluminum alloy materials integral casting forming, so it can improve the contact area of water heat exchanger channels and housing effectively, and then improve the heat exchange efficiency and the structural strength of heat exchanger.
Description of drawings: Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the annexation schematic diagram of Fig. 1 middle shell 2, water inlet 5, delivery port 6.
Fig. 3 is the annexation schematic diagram of Fig. 1 middle shell 2, water heat exchanger channels 3, heat exchange unit 4.
Fig. 4 is the structural representation of heat exchanger applications in the gas heater among Fig. 1.
The specific embodiment: shown in accompanying drawing 1, accompanying drawing 2, accompanying drawing 3, accompanying drawing 4, present embodiment comprises housing 2, heat exchange unit 4, the inner chamber of housing 2 is provided with combustion chamber 1 and Heat Room 8, the part of heat exchange unit 4 is arranged in the Heat Room 8, another part is arranged in the combustion chamber 1, be provided with water heat exchanger channels 3 in the wall of housing 2, the cross section of water heat exchanger channels 3 can be circle, ellipse or square, be provided with heat exchange unit 4 in the combustion chamber 1, the heat exchanger fin 11 in the heat exchange unit 4 can be cylinders such as cylinder, square cylinder, triangle cylinder or waveform cylinder.
The heat exchanger of gas heater uses the red copper material to make usually, China's copper scarcity of resources, and bauxite resource is abundant relatively, for avoiding the copper material price to sharp rise product cost is gone up, and housing 2, heat exchange unit 4 and water heat exchanger channels 3 can be aluminum alloy materials and make.
Water heat exchanger channels 3 can be evenly distributed in the wall of housing 2, also can be non-uniformly distributed in the wall of housing 2, and water heat exchanger channels 3 is evenly distributed in the wall of housing 2 in the utility model.
The inwall of water heat exchanger channels 3 can be provided with spoiler, set up spoiler after, can increase the heat exchange efficiency of heat exchanger, also can prolong the service life of heat exchanger simultaneously.
When the utility model is applied on the gas heater, heat exchanger is installed in the end of burner 10 in the gas heater, the two ends of water heat exchanger channels 3 are provided with water inlet 5 and delivery port 6, and water inlet 5 is communicated with water inlet pipe 9 in the gas heater, and delivery port 6 is communicated with outlet pipe 7 in the gas heater.
During gas heater during operate as normal, the combustion gas of ejection is in the combustion chamber of heat exchanger 1 internal combustion in the burner 10, cold water flows into water heat exchanger channels 3 from water inlet 5, in heat exchanger, fully become hot water from delivery port 6 outflow water heat exchanger channels 3 after the heat exchange, flow to outlet pipe 7, flow out from outlet pipe 7 at last and use for the user.
Because water heat exchanger channels 3 is arranged in the wall of housing 2, the contact area of water heat exchanger channels 3 and housing 2 effectively increases, and heat exchange unit 4 is arranged in the combustion chamber 1 and Heat Room 8 in the housing 2 simultaneously, and then improves the heat exchange efficiency of heat exchanger.
Heat exchanger is an integral casting forming, does not weld or the expanded joint point structural strength height.Water heat exchanger channels 3 is arranged in the wall of housing 2 and makes the heat exchange better effects if, also make housing 2 bulk temperatures of heat exchanger even, and temperature is lower, and the heat exchanger heat transfer stationary performance is better, and volume compact can effectively be saved the space simultaneously.
Because heat exchanger adopts integral casting process to make, the aluminium alloy of its surfaces externally and internally forms the oxide layer of consistency of thickness by high-temperature oxydation, need not to carry out surface treatment again, therefore has good Corrosion Protection, also can prolong the service life of water heater.
