Description
Technical field
The present invention relates to air-conditioning technical fields, more particularly to a kind of metal adapter, frequency converter and air conditioner
Group.
Background technique
Current centrifugal refrigerating machines and other large-size air conditioning units, there are the service life of frequency converter well below
The phenomenon that its projected life, or even there is a phenomenon where frequency converters to burn in unit running process.To the unit to break down into
It is found when row case study, the frequency converter for not using switching copper sheet is significantly larger than using the frequency converter failure rate of switching copper sheet.It is right
For the frequency converter using switching copper sheet, the source that frequency converter breaks down is that unit is transferred copper sheet in the process of running mostly
The generation for phenomena such as being melted by burning, causing frequency converter short-circuit.
It is generated heat according to copper sheet serious phenomenon, finds out following two points reason:
One reason for this is that it is one of most important factor that contact area, which is unable to reach theoretical value, between copper sheet and copper sheet.Copper sheet
It is contacted between copper sheet by plane, it is to lead to copper sheet and copper sheet contact area that copper sheet machining accuracy, which is unable to ensure, at present
The main reason for being unable to reach theoretical value, since copper sheet machining accuracy is irregular, the contact area between copper sheet and copper sheet is remote
Theoretical value is far not achieved.In actual use, perfect condition is face contact, and is more that point connects in actual operation
Touching, contact area greatly reduces between copper sheet and copper sheet, and resistance value between copper sheet and copper sheet is caused to increase, and fever is serious, leads to copper
Piece, which is burnt, to be melted
Another reason is then the heat dissipation capacity of the unit time of copper sheet lower than the calorific value in its unit time.Copper sheet is long-term
In the state that fever can not seriously radiate in time, and nearby there is no effective cooling measures for copper sheet, are easy to happen copper sheet change
The phenomenon that shape is even burnt.
Summary of the invention

Through-hole 14, the through-hole on two metal adapters is coaxial.
It should be noted that recess portion or protrusion can also only be arranged in the present invention on metal adapter.For example, two
In metal adapter, recess portion is set in the mating surface of one of metal adapter, the mating surface of another metal adapter
The protrusion of recesses fit on the upper one of metal adapter of setting；It is arranged in the mating surface of one of metal adapter convex
Portion, the recess portion of setting and the protrusion cooperation on one of metal adapter in the mating surface of another metal adapter.
But it is equipped with recess portion and protrusion simultaneously on metal adapter, it transfers without in addition designing with the metal of this type
The metal adapter that part specially cooperates largely realizes the generalization of metal adapter, a kind of metal switching of type
Part is achieved that the switching between metal adapter.It such as is all to be provided with recess portion and convex on two metal adapters in Fig. 3
Portion, it is only necessary to the metal adapter of this kind of type.
As shown in figure 4, second embodiment and the first embodiment the difference is that: in order to which metal is transferred
The heat that part generates is radiated in time, the heat dissipation effect of raising metal adapter, in the non-mating surface 15 of metal adapter 10
Equipped with the radiator structure to radiate for metal adapter 10.In the present embodiment, radiator structure is radiating groove 17, and radiating groove 17 increases
The contact area of metal adapter and air, increases heat dissipation area, the heat that metal adapter generates by radiating groove into
Row heat dissipation, can reduce the heat of metal adapter.
The non-mating surface 15 of metal adapter 10 is equipped with the first protrusion 16, and the first protrusion 16 is by the non-of metal adapter 10
Mating surface 15 outwardly protrudes to be formed, and radiating groove 17 is formed between two neighboring first protrusion 16.
The shape of radiating groove may be configured as linear type, zigzag, rectangular-ambulatory-plane or other irregular shapes.
Cold converter module is provided in the frequency converter of centrifugal refrigerating machines, when cooling down to frequency converter, on a small quantity
Cold air pass through metal adapter when and can take away compared to the existing more heats of metal adapter, the lost efficiency of heat
Increment rate depending on metal adapter surface area.
As shown in figure 5, the third embodiment and second of embodiment the difference is that: in order to which metal is transferred
The heat that part generates is radiated in time, improves the heat dissipation effect of metal adapter, and radiator structure is fin 18, metal adapter
Heat be transmitted on fin 18, the heat dissipation of metal adapter is realized in contact by fin 18 with air, can be reduced metal and be turned
The heat of fitting.
The second protrusion 19 is additionally provided in the non-mating surface 15 of metal adapter 10, the second protrusion 19 is by metal adapter 10
Non- mating surface 15 outwardly protrudes to be formed, and mounting groove is formed between two neighboring second protrusion 19, and fin 18 is set in mounting groove simultaneously
With the non-cooperation face contact of metal adapter.Certainly, the non-mating surface 15 of metal adapter 10 can also be protruded to form three outside
Second protrusion, four the second protrusions, it is even more.
Fin 18 is fixed in mounting groove by fixing piece 60, and fixing piece 60 is column and is bent into U-shaped, and fixing piece 60 is worn
Be located in the second protrusion 19 and fin 18, so that fin 18 is fixed in mounting groove, the both ends of fixing piece 60 respectively with screw
Cooperation.Fin can or inclination vertical with the non-mating surface of metal adapter.
As shown in Figure 6 and Figure 7, in the present embodiment, fixing piece 60 is two, and two fixing pieces 60 are between the upper and lower every setting.
The shape of fin may be configured as round or rectangle, and fin is vertical with the non-mating surface of metal adapter or inclination is closed
System.
It should be noted that radiator structure may include radiating groove and fin, the calorific value of metal adapter is being reduced in this way
While, the heat dissipation effect of metal adapter is also improved, the calorific value and fever of reduction metal adapter that can be more obvious
Serious phenomenon.
As shown in figure 8, the 4th kind of embodiment and the first embodiment the difference is that: 12 shape of recess portion is Back Word
Rectangular-ambulatory-plane is surrounded between shape or multiple recess portions 12；13 shape of protrusion surrounds Back Word between rectangular-ambulatory-plane or multiple protrusions 13
Shape；Or rectangular-ambulatory-plane is surrounded between multiple recess portions 12 and multiple protrusions 13.
In other embodiments, lobe shape may be zigzag, and recess shapes can be zigzag.
The present invention also provides a kind of frequency converter, frequency converter includes above-mentioned metal adapter.
The present invention also provides a kind of air-conditioner sets, and including above-mentioned frequency converter, air-conditioner set is centrifugal refrigerating machines.
Above specific embodiment is only to the design illustrated the present invention, and those skilled in the art are in this hair
Various deformation and variation can be made under bright design, these deformations and variation are included within protection scope of the present invention.
