Connect method and device.
Background technology
With the development of the technology of air-conditioning and refrigeration industry and the further stringent control of environmental regulation, heat exchange unit is improved
The coefficient of heat transfer of itself is the overall heat exchange performance for improving heat exchanger, makes up the system caused by alternative refrigerant self reason
The necessary means of the reduction of cold performance.There are problems that refrigeration performance decline based on existing refrigerant and does not develop yet effective
Research object is switched to air-conditioning and the basic element of character-heat exchanger element of refrigeration by Substitute Working Medium, relevant enterprise and scientific research institution,
That is hollow copper tubing can effectively be solved the above problems by improving the heat exchange property of hollow copper tubing.
The copper pipe of air conditioner refrigerating is mostly the hollow copper core of thin-walled minor diameter, as shown in Figure 1, to provide buffering to refrigerant flowing
Area promotes refrigeration effect, is typically designed the bigger hollow copper tubing region of one section of caliber, and manufacture is in 1201 liang of hollow copper tubing
Side is socketed hollow copper core 1202, hollow copper core 1202 and 1201 clearance fit of hollow copper tubing respectively, to prevent refrigerant from flowing through sky
Heart copper pipe leaks, then hollow copper core 1202 and hollow copper tubing 1201 is carried out socket boxing processing, both ensure that sky in this way
The leakproofness of heart copper pipe 1201, and convenient refrigerant used cycle.
Welding mean common at present has argon arc welding, high frequency induction welding and soldering.Argon arc welding is that one kind relying primarily on electricity
The welding manner of metallurgical reaction occurs for arc heating fusing base material, and weld seam is difficult to be made tiny, and welding heat affected zone is larger so that its
The socket hollow copper tubing of large scale, wall thickness more than 1mm is generally used for weld, and it is hollow to be not suitable for tiny, thin-walled the socket of welding
Copper pipe；High frequency induction welding is the main method of welding socket hollow copper tubing, but since gap when different tube diameters copper pipe is socketed is matched
Property is closed, the kelvin effect both in its welding process is asynchronous with approach effect so that the base material of local melting is easy logical
It crosses gap and flows into inside copper pipe and form that weldering is stifled, and surface contaminants cleaning is not also easy to totally cause weld porosity, easy during military service
Leakage and problem of Cracking occurs, while the technological parameter welded is difficult to set up, significantly limit production efficiency and quality；For pricker
, then it is poor to there is welding joint mechanical property, it is difficult to which the deficiency for ensureing leakproofness directly affects the repetition of welding quality in weldering
Property, the problems such as crackle easily occurs during being on active service, leaks.
Laser welding is a kind of high-quality welding technology quickly grown in recent years, and hot spot is tiny so that weld seam
It is extremely narrow, welding heat affected zone is minimum, become many high-accuracy, high-quality welding preferred techniques.But for the overlap joint of socket pipe
For weldering, since its welding structure itself requires enough soldering areas to ensure telescopic lap splice integral strength mechanical property, singly
Road laser welding cannot be satisfied requirement, need multiple tracks built-up welding, this makes, and technique is cumbersome, cost increases, and limits laser welding and exists
The application in this field.
