Specific embodiment
In order to which the purpose of the present invention, scheme and advantage is more clearly understood, with reference to embodiments, the present invention is carried out
It is further described.It should be appreciated that specific embodiment described herein is not used to limit this only to explain the present invention
Invention.In addition, as long as technical characteristic involved in invention described below different embodiments is not formed each other
Conflict can be combined with each other.
It please refers to Fig.1, traditional heat exchanger 100 includes:Multiple sequentially connected long U pipes 10 and multiple fins 20.Fin
20 is flaky, has certain surface area, (can depend on actually being answered for rectangular or other suitable profiled shapes
With environment).Multiple fins 20 are disposed on according to certain outside long U pipes 10, form the radiator structure with large surface area.
The operation principle of heat exchanger is by multiple fins being provided at predetermined intervals, and extends the surface area of long U pipes so that
Liquid or gas for being flowed through in long U pipes etc. can have great heat dissipation area, distribute heat in extraneous air.
The following assembly method of usual finned heat exchanger generally use：First, in accordance with the needs used, customization is multiple
Have figurate aluminum fin-stock, and on each fin 20, offer the mounting hole coordinated with long U pipes, multiple long U pipes 10
It sequentially passes through, so as to which multiple fins 20 be made to be set in outside long U pipes 10.Determining the opposite position between fin 20 and long U pipes 20
After putting, tube expansion is carried out to long U pipes 10 using hydraulic casing roller or other suitable tube-expanding devices to long U pipes 10, makes its pipe
Diameter expands.Long 10 meeting of U pipes after caliber expansion and mutually squeezed between the mounting hole of fin 20, make fin 20 and long U pipes 10 it
Between keep be in close contact, it is ensured that fin stabilization is fixed on long U pipes.
In the production process, long U pipes need have certain tube expansion and welding performance to traditional heat exchanger, and the welding of copper
It is better than the performance of aluminium with tube expansion performance, therefore the general selection copper pipe of traditional long U pipes is managed as long U, and fin material is then selected
Fin aluminium.As recorded in background technology, on the one hand, using copper pipe as refrigerant transmission channel, heat exchanger total quality meeting
It is relatively heavy；On the other hand, due to including the techniques such as tube expansion, welding, it is therefore desirable to which a large amount of personnel and equipment complete the system
Make technique；Also, during tube expansion, copper shape pipe and aluminum fin-stock can lead to degradation of heat exchange performance there are thermal contact resistance.
Based on this, the embodiment of the present invention provides a kind of novel heat exchanger, which uses aluminum pipe and foamed aluminium phase group
The mode of conjunction is to substitute the fin-tube type heat exchanger structure that traditional copper pipe and aluminum pipe coordinate, and the novel heat exchanger structure
Simply, manufacture craft is simple, needs not move through tube expansion and can obtain, also, due to the combination using aluminum pipe and foamed aluminium
It can be with relatively reduced thermal contact resistance, and the surface area of foamed aluminium is larger, increases heat exchange area, therefore the novel heat exchange utensil
There is good heat exchange property.
The concrete structure and manufacture craft of the heat exchanger described in detail below, referring to Fig. 2, Fig. 2 is the embodiment of the present invention
The structure diagram of a kind of heat exchanger 200 provided, as shown in Fig. 2, the heat exchanger 200 includes：Foam aluminum component 20 and aluminum pipe 22.

It is in close contact, by the foaming structure of foam aluminum component, the heat dissipation area of aluminum pipe 22 is extended, so as to fulfill the heat exchange work(of heat exchanger
Energy.
Wherein, can corresponding shape and size be made according to actual needs in aluminum pipe 22, be installed in foam aluminum component 20,
Form the pipeline flowed through for refrigerant.For example, aluminum pipe 22 can be made snakelike or U-shaped, it is installed in foam aluminum component 20.Foamed aluminium
Part 20 can be cut into corresponding shape and size according to actual needs, form radiator structure.Aluminum pipe 22 and foam aluminum component 20 it
Between any suitable mounting means may be used installed, form the heat exchanger 200.
Heat exchanger provided in an embodiment of the present invention is obtained using the combination of foam aluminum component and aluminum pipe, due to aluminum pipe
Density be less than the density of copper pipe, the overall weight of foam aluminum component is less than the weight of aluminum fin-stock, therefore, using foam aluminum component and aluminium
The heat exchanger of pipe composition advantageously reduces the weight of heat exchanger.In addition, heat exchanger entirety corrosion potential approaches, tradition is avoided
Heat exchanger and leads to seriously corroded because there are larger potential difference between copper pipe and aluminum fin-stock；Secondly, foam constructed of aluminium increases scattered
Hot area so that the heat exchange efficiency of heat exchanger greatly promotes.

In other embodiments, the shape of the first foamed aluminium board 24 and the second foamed aluminium board 26 can also carry out suitable according to actual needs
Change.
In the present embodiment, the first foamed aluminium board 24 and the second foamed aluminium board 26 are open cell foam aluminium, open cell foam
The heat exchange area of aluminium will be far longer than entity aluminium radiator, have good heat exchange function.In some embodiments, open-cell steeps
The inside of foam aluminium has several interconnected through-holes, which is convenient for air circulation, increases the heat dissipation of heat exchanger 200
Area so that the heat exchange efficiency of heat exchanger greatly promotes.
In the present embodiment, aluminum pipe 22 includes refrigerant inlet 222 and refrigerant exit 224 as shown in Figure 1, refrigerant inlet
222 and refrigerant exit 224 protrude from the end face of the first foamed aluminium board 24 and the second foamed aluminium board 26.Carry out heat exchange when
It waits, refrigerant is inputted from refrigerant inlet 222, and heat is sent to the first foamed aluminium board 24 and the second foamed aluminium board by aluminum pipe 22
26, to increase the surface area of aluminum pipe 22, distribute heat in extraneous air.
Heat exchanger provided in this embodiment uses the combination of foamed aluminium and aluminum pipe, on the one hand, due to foamed aluminium and aluminium
Corrosion potential approaches between pipe, reduces the corrosion rate of heat exchanger, avoids traditional heat exchangers because being deposited between copper pipe and aluminum fin-stock
In larger potential difference, and lead to seriously corroded；On the other hand the heat exchanger lighter weight obtained, and foam constructed of aluminium increases
Heat dissipation area so that the heat exchange efficiency of heat exchanger greatly promotes.
The embodiment of the present invention also provides a kind of production method of above-mentioned heat exchanger, and referring specifically to Fig. 4, Fig. 4 is the present invention
