Description
Technical field
The application is related to technical field of heat exchange, more particularly to heat exchanger and the domestic gas heat using the heat exchanger
Hydrophone and wall-hung boiler.
Background technology
The heat exchanger generally use fin-tube type heat exchanger for being traditionally used for boiler or gas heater carries out hot friendship
Change, when this kind of heat exchanger works, water at low temperature flows through from metal tube, and high-temperature flue gas is then from fin clearance by low temperature
Water carries out heat exchange by metal tube and its fin of outside with high-temperature flue gas, makes water temperature rise and flue gas temperature in pipe so as to reach
Spend the effect reduced.However, the defects of this mode, is, flue gas in fin-tube type heat exchanger by when easily form STATIC CORRECTION USING APPROXIMATE LAYER
The air-flow of shape so that the heat exchanger effectiveness of high-temperature flue gas and cold water is not especially desirable.
Utility model content
The purpose of the application is to provide a kind of heat exchanger and the gas heater using the heat exchanger, the letter of its structure
It is single and the heat exchanger effectiveness of flue gas and cold water can be improved.
This application discloses a kind of heat exchanger of Household gas water heating device, including it is hollow tubbiness shell, reciprocal circuitous
The water pipe set is returned, and is filled in porous foam metal (porous foam metal) filler of the enclosure；Institute
The one end for stating shell sets high-temperature flue gas entry, the other end to set low-temperature flue gas to export, the water inlet and delivery port of the water pipe
The side of the shell is arranged on, wherein, the water pipe is at least partially disposed on the enclosure and by the porous bubble
Foam metal charge coats, wherein, PPI (par per inch) index of the porous foam metal filler is 5~50.
In feasible embodiment, the porous foam metal filler be Porous foam aluminimun, porous foam copper or
One or more in porous foam stainless steel filler.
In feasible embodiment, the porous foam metal filler is fixedly connected on the pipe outer wall.
The application further simultaneously discloses a kind of domestic gas-fired water heater and a kind of Household gas-fired wall-mounted stove, using foregoing heat
Exchanger.
In order to be further understood that the feature of the application and technology contents, refer to below in connection with the detailed of the application
Illustrate and accompanying drawing, however accompanying drawing only provide with reference to and explanation use, be not used for being any limitation as the application.
Brief description of the drawings
The foregoing and other side of the application will be discussed in detail more completely to be managed by what is done with reference to the accompanying drawings
Solution and understanding, in the accompanying drawings：
Fig. 1 show a kind of schematic diagram of embodiment of the application；
Fig. 2 show the schematic diagram of the application another embodiment.
Embodiment
For help those skilled in the art definitely understand this application claims theme, below in conjunction with the accompanying drawings in detail
The embodiment of the application is described.
It is shown in Figure 1, it is a kind of embodiment of the application.This application discloses one kind to be used for gas heater
Heat exchanger, it includes hollow tubbiness shell 100, the water pipe 200 of reciprocal roundabout setting, and is arranged on the shell
Inside 100, be filled between reciprocal roundabout water pipe 200, the porous foam metal in space is filled out between water pipe 200 and shell 100
Fill thing 300.It is arranged on as shown in figure 1, water pipe 200 is most of inside shell 100, and is arranged on the water pipe 200 inside shell 100
Coated by porous foam metal filler 300.
One end of the shell 100 sets high-temperature flue gas entry 110, the other end to set low-temperature flue gas to export 120, the water
The water inlet 210 and delivery port 220 of pipe 200 are arranged on the side of shell 100 and respectively close to the both ends of the shell 100, its
In, the water inlet 210 is close to the high-temperature flue gas entry 110, and delivery port 220 is close to low-temperature flue gas outlet 120.Can be with
Understand, in other embodiments, water inlet 210 and delivery port 220 can also be arranged as required in the side of shell 100
Other rational positions.When heat exchanger works, the cold water in water pipe 200 is during the Internal Transfer of shell 100 with leading to
Enter the inside of shell 100 and the high-temperature flue gas through porous foam metal filler 300 fully carries out heat exchange.Described in herein
One end, the other end refer to the top or bottom of shell 100；Side refers to the lateral wall of shell 100.
The porous foam metal being related in the application is a kind of metal material containing high density micro-through-hole, is existing skill
Art.In various embodiments, the porous foam metal filler 300 can be Porous foam aluminimun, porous foam copper or
Porous foam metal or the foamed alloys such as person's porous foam stainless steel filler.High-temperature flue gas is entered outer by entrance 110
, it is necessary to be discharged again by exhanst gas outlet 120 through porous foam metal filler 300 behind the inside of shell 100.Due to porous foam metal
A large amount of micro-through-holes in filler 300 be present, flue gas can be forced to pass through these through holes in the form of very disorderly, thus in high temperature
During fumes cross porous foam metal filler 300 sufficient heat exchange is carried out with the current in water pipe 200.Relative to
For fin-tube type heat exchanger, the characteristic of the disorderly flowing of flue gas improves the coefficient of heat transfer in the application, while highdensity small
Through hole again increases the specific surface area of heat exchange, so that the heat exchange efficiency of heat exchanger has obtained great lifting.
As preferable embodiment, the PPI indexes of the porous foam metal filler are 5~50.In this aperture
Under size, the pore structure of porous foam metal both has good heat conduction specific surface area, is able to ensure that flue gas successfully leads to again
Cross, so as to be sufficiently carried out exchanging heat.
In addition, in order to ensure porous foam metal filler is not subjected to displacement in shell 100, and fully with water pipe 200
Outer wall is in contact, and in some embodiments, the porous foam metal filler 300 is fixedly connected by modes such as solderings
In the pipe outer wall.
It is shown in Figure 2, be the application another embodiment schematic diagram, it is different from aforementioned embodiments it
It is in water pipe 200 is provided entirely in inside shell 100.It is understood that this design can equally cause flue gas and cold
Sufficient heat exchange is carried out between water.
Similarly, it will be understood by those skilled in the art that gas heater or wall-hung boiler using aforesaid heat exchangers
Also there is the advantages of heat exchange efficiency is high.
Although having been shown and described the application based on specific embodiment, the application is not restricted to shown thin
Section.On the contrary, in the range of claim and its equivalent substitution, the various details of the application can be modified.
