Embodiment
Below, the present invention is specifically described by exemplary embodiment.It should be appreciated, however, that not entering one
In the case of step narration, element, structure and features in an embodiment can also be advantageously incorporated into other embodiment
In.
In the description of the invention, it is necessary to explanation, the instruction such as term " interior ", " outer ", " on ", " under ", "front", "rear"
Orientation or position relationship be based on position relationship shown in the drawings, be for only for ease of description the present invention and simplify description, and
It is not instruction or implies that signified device or element there must be specific orientation, with specific azimuth configuration and operation, therefore
It is not considered as limiting the invention.
It is the structural representation of refrigerant fin of the present invention referring to Fig. 1-Fig. 3.As illustrated, the refrigerant radiating of the present invention
Piece, including radiator 1, the radiator 1 can be tabular, sheet or bulk, or other irregular shapes, herein for it
Concrete shape is not limited.Interference fit in heat dissipation channel, the heat dissipation channel is formed with the radiator 1 negotiable cold
The hot channel 2 of matchmaker, refrigerant circulates out of described hot channel 2, so that the hot channel 2 exchanges heat with the radiator 1.Make
Used time, refrigerant fin is positioned over by heater, refrigerant circulates out of hot channel, refrigerant is changed with hot channel first
Heat, then hot channel further exchanged heat with heater, because of the interference fit between hot channel and radiator so that
Refrigerant in circulation hot channel can rapidly complete heat exchange, improve heat exchange efficiency.
Referring particularly to Fig. 2, the hot channel 2 has shape on refrigerant import 21 and refrigerant exit 22, the hot channel 2
Into there is bending part 23, the bending part 23 is formed at the side of radiator 1, the refrigerant import 21 and the refrigerant exit 22
It is formed at the radiator 1 opposite side relative with the bending part 23.It should be noted that showing refrigerant import 21 in Fig. 2
The right side of refrigerant exit 22 is arranged at, and in invention, the specific set location for refrigerant import and refrigerant exit is not limited
It is fixed, also do not limited for the spacing between refrigerant import and refrigerant exit.
In addition, the radiator 1 is preferably the rigid material with thermal conductivity;The hot channel 2 is preferably can be outside
The soft materials of the lower deformation of power effect.Based on this, the radiator 1 is preferably aluminum alloy material, and the hot channel 2 is preferably
Metal copper material.Radiator 1 selects aluminum alloy material, it is advantageous that, not only thermal conductivity is high, and hardness is high, and aluminum alloy material
Relatively economical cost is smaller;And hot channel 2 selects metal copper material, its advantage is lain also in, and thermal conductivity is higher and belongs to soft
Material, financial cost is relatively low.
In addition, the heat dissipation channel of the present invention is two parallel channels through radiator 1.The hot channel 2
For " U " type or " Qian " type.When hot channel 2 is matched with radiator 1, its two ends end stretch to two of heat dissipation channel it is parallel logical
In road, kink indwelling is in the outside of radiator 1.In addition, above-mentioned hot channel 2 is preferably U-shaped, because of U-shaped kink transition
It is more round and smooth, larger stress will not be produced, service life is extended.
Referring to Fig. 4, present invention also offers a kind of air-conditioning, including heater 3, fit and be provided with the heater 3
The refrigerant fin stated.Specifically describe, will not be repeated here for refrigerant fin because above-mentioned.Wherein, the heater 3 can
For frequency conversion substrate or blower fan module.Meanwhile, in the present invention, other structures for air-conditioning and without modification are cold only for its
Matchmaker's fin is improved, therefore, and air-conditioning of the invention does not refer to that structure is prior art, in the present invention no longer to it
Concrete structure is repeated.
In addition, present invention also offers a kind of processing method of refrigerant fin, for processing refrigerant radiating described above
Piece, comprises the following steps:The hot channel is inserted in the heat dissipation channel;The swollen head of electric tube expander is stretched into radiating tube
In road, and hot channel is swollen, be interference fitted until hot channel is swollen to heat dissipation channel.
Further, above-mentioned expansion method is specifically described:Electric tube expander can select hydraulic casing roller or mechanical expanding
Machine, two kinds of electric tube expanders are prior art, and its structure is not specifically described at this.It is preferably mechanical expanding in the present invention
Machine.
Wherein, when from hydraulic casing roller, hot channel is inserted in heat dissipation channel first, Hydraulic Expansion is ready for
Pipe machine:Copper tube aluminum string is good, and header type elbow is all welded, lead to high pressure refrigerant (such as water), hydraulic pressure is increased to 1200-
200kg/cm2When, copper pipe is swollen with hydraulic coupling, itself and aluminium flake is in close contact, until hot channel it is swollen to and heat dissipation channel
Interference fit.This processing method is that technique is simple to operation.The disadvantage is that, needing to clean equipment after tube expansion.
When from mechanical expanding machine, the explanation by taking expander roll formula mechanical expanding as an example:Because hot channel is soft, and radiate
Body is hard state, and the swollen head of steel alloy is pushed into hot channel internal diameter by force with mechanical force, hot channel is swollen, the calculating of tube expansion amount
It is finally that guarantee hot channel and radiator are tight including hot channel external diameter overgauge, aluminium flake hole internal diameter minus deviation, poling spacing
Close combination, further increases bulk, so as to form interference fit between hot channel and radiator.The value of the magnitude of interference can be advance
Setting, the value standard of the magnitude of interference will also ensure thermal shock for that should ensure self shrinking of the hot channel after mechanical expanding
In the presence of, hot channel is combined closely with radiator inwall, to reduce thermal resistance, it is ensured that heat transfer.It is not required in the processing method
Additionally to open up gabarit mould, the size of hot channel and heat dissipation channel is typically all standardization, thus process into
Product uniformity preferably, also relatively unify by heat-sinking capability.
Below, in order to further protrude creativeness of the invention, by the processing method of the present invention and existing preferable punching press
Heat-sinking capability of processing method etc. carries out Experimental Comparison and is analyzed as follows:
In this experiment, the refrigerant fin of expansion method of the present invention will be used respectively with using prior art punching press
The heat-sinking capability of the refrigerant fin of mode is contrasted, it is necessary to illustrate, in this experiment, the refrigerant fin of selection, which is removed, to be added
Work mode is different, and other structures etc. are consistent.
The Experimental Comparison table of the present invention of table 1 and prior art
By the above-mentioned experimental result of table 1, using the processing method of the present invention, its heat-sinking capability is significantly stronger than existing skill
The processing method used in art, and the processing method of the present invention is easily operated, and with more practicality, cost performance is higher.
