Description
Technical field
The present invention relates to the welding structure and the welding method of aluminum accumulator and heat exchanger with welding structure of aluminum accumulator.
Background technology
Usually, in the heat exchanger in being used in domestic refrigerator etc., the welding structure of aluminum accumulator and aluminum tubular conductor is known following hydraulic accumulator welding structure: the connecting portion of aluminum accumulator and aluminum tubular conductor interior week insert the stainless steel sleeve, and be welded to connect the periphery of portion.But, in recent years,, in heat exchanger, also require to improve soldering reliability for the leakage of weld part as the inwall functional part for household appliances such as refrigerator use combustible refrigerant in using cold-producing medium.In order to realize further cost degradation, in heat exchanger, also require productivity height and the low product of cost again.But, because the aluminium weld part is the structure that is easy to generate failure weldings such as leakage, and cause productivity variation on welding is adjusted or produced, so cost degradation is difficult as reason.
By above situation as can be known, need a kind of almost do not have failure welding, welding structure and welding method that productivity is high.
Fig. 4 is that the spy opens the existing aluminum tubular conductor welding structure profile that the 2002-188765 communique is put down in writing.
As shown in Figure 4, the aluminum accumulator welding structure prevents that by the aluminium penetration of cold-producing medium when the aluminum tubular conductor 4 of internal flow, aluminum accumulator 5 and the welding stainless steel sleeve 10 of usefulness from constituting.The part of aluminum tubular conductor 4 is provided with pit part 11, and stainless steel sleeve 10 is inserted into the position until this pit part 11.In addition, in order to prevent that because of cold-producing medium directly is back to the compressor fault that causes in the compressor aluminum tubular conductor 4 bendings are not so that aluminum tubular conductor outlet 4a directly exports 5a towards aluminum accumulator, aluminum tubular conductor 4 has the 4b of bending machining portion.Then, after aluminum tubular conductor 4 is inserted in the aluminum accumulator 5, the periphery of the superimposed connecting portion 7 of welding of aluminum conduit 4 and aluminum accumulator.The aluminum accumulator welding structure is such aluminum tubular conductor welding structure.
But, in above-mentioned existing structure, promptly in above-mentioned so-called structure, in the aluminum tubular conductor 4 that inserts, have the 4b of bending machining portion to aluminum accumulator 5 insertion aluminum tubular conductors 4.Like this, when aluminum tubular conductor 4 was inserted in aluminum accumulator 5, the inner end diameter of aluminum accumulator 5 must be considered the insertion of aluminum tubular conductor 4, and is promptly fully wide than the external diameter of aluminum tubular conductor 4.Therefore, sometimes produce failure welding because of following situation, thereby thereby when promptly welding the gap of the insertion section between aluminum tubular conductor 4 and the aluminum accumulator 5 become in the time of can not guaranteeing this situation of gap that is suitable for welding and welding greatly aluminum tubular conductor 4 easily motion be easy to generate this situation that departs from.
And then, depart from the inside dimension deterioration in accuracy that fixing this situation of position of aluminum tubular conductor 4 of being difficult to causes the aluminum accumulator 5 of aluminum tubular conductor 4 thereby on aluminum tubular conductor 4, be easy to generate.So, be difficult to sometimes to keep to prevent that cold-producing medium from being the curved shape of the aluminum tubular conductor 4 that is provided with of purpose to the direct backflow of compressor, on the position of aluminum tubular conductor front end 4a, produce skew, thus the flowing instability of cold-producing medium.
Again, in order to determine the insertion position of aluminum tubular conductor 4, the use of insertion position decision anchor clamps is absolutely necessary.Sometimes be difficult to improve the productivity of product because of following situation, promptly anchor clamps install or the insertion of aluminum tubular conductor 4 on expend time in this situation or the 4b of bending machining portion etc., production process must be set or production this situation that necessitates man-hour being inserted in stainless steel sleeve 10 in the aluminum tubular conductor 4 more deeply after.
Summary of the invention
The welding structure of aluminum accumulator, comprise and have that first welding bead (beading) adds aluminum tubular conductor, the pull and stretch processing aluminum pipe two ends of the Ministry of worker and the aluminum accumulator and the stainless steel pipe that are shaped, stainless steel pipe is inserted in the aluminum tubular conductor, aluminum tubular conductor is inserted in the aluminum accumulator and adds the Ministry of worker until first welding bead, and aluminum tubular conductor, aluminum accumulator and stainless steel pipe are soldered at superimposed connecting portion.
Heat exchanger has the welding structure of above-mentioned aluminum accumulator.
The aluminum accumulator welding method, comprise and have that first welding bead adds aluminum tubular conductor, the pull and stretch processing aluminum pipe two ends of the Ministry of worker and the aluminum accumulator and the stainless steel pipe that are shaped, be inserted in the aluminum tubular conductor after first welding bead adds the Ministry of worker at stainless steel pipe, aluminum tubular conductor is inserted to the aluminum accumulator end, and aluminum tubular conductor, aluminum accumulator and stainless steel pipe are soldered at superimposed connecting portion.
