The specific embodiment is as follows:
As shown in fig. 1 to 7, the embodiment, a copper pipe connected evaporator, comprises an evaporator main body 10 and a copper pipe inlet pipe 20, wherein a plurality of axially extending long grooves 12 are formed on the inner side wall of an inlet end 11 of the evaporator main body 10, an extension connecting part 21 with the outer diameter smaller than that of the discharge end of the copper pipe inlet pipe 20 is formed at the end part of the discharge end of the copper pipe inlet pipe 20, a plurality of axially extending outer long grooves 22 are formed on the outer side of the extension connecting part 21, the extension connecting part 21 is inserted and sleeved in the inlet end 11, the outer side wall of the extension connecting part 21 is clung to or close to the inner side wall of the inlet end 11, annular grooves 23 are formed on the bottom end and the outer side wall of the upper end of the extension connecting part 21, and the annular grooves 23 are communicated with all the outer long grooves 22. The welding flux is filled in all the long grooves 12, the outer long grooves 22 and the annular grooves 23, and during welding, the welding flux is melted and fills all the long grooves 12, the outer long grooves 22 and the annular grooves 23 through brazing, and as the conical expansion part is formed on the outer side wall at the outer end of the inlet end 11, the welding flux is in the conical expansion part when the excessive welding flux flows out, so that the welding flux is prevented from flowing out.
All outer long grooves 22 of the extension connecting portion 21 are uniformly distributed on the outer side wall of the extension connecting portion 21 by taking the central axis of the extension connecting portion 21 as the center, all long grooves 12 formed on the inner side wall of the inlet end 11 are uniformly distributed on the inner side wall of the inlet end 11 by taking the central axis of the inlet end 11 as the center, all outer long grooves 22 and the long grooves 12 are staggered, so that the welding wall surface is increased, the welding firmness and the welding sealing effect are further improved, and the generation of air holes is reduced.
After the welding is finished, the same heat shrinkage sleeve 1 is sleeved on the outer wall surface of the inlet end 11 and the discharge end of the copper pipe inlet fitting 20, and the inner wall surface of the heat shrinkage sleeve 1 is tightly attached to the outer wall surface of the inlet end 11 and the outer wall of the discharge end of the copper pipe inlet fitting 20 through heat shrinkage, so that sealing is realized.
Then, the elastic heat preservation sleeve 2 is sleeved on the outer side walls of the inlet end 11 and the discharge end of the copper pipe inlet fitting 20, part of the outer side walls of the inlet end 11, part of the outer side walls of the discharge end of the copper pipe inlet fitting 20 and the outer side walls of the heat shrinkage sleeve 1 are pressed against the inner side walls of the elastic heat preservation sleeve 2, and therefore heat preservation and sealing effects are achieved.
The copper pipe inlet pipe fitting 20 with the required length is designed, so that the length is short, however, the whole copper pipe fitting is a copper pipe body, the problem that air holes are formed in the middle of the copper pipe body when the copper pipe fitting is welded with the inlet end 11 of the evaporator main body 10 is avoided, meanwhile, the staggered long grooves 12 and the outer long grooves 22 are arranged in the copper pipe fitting greatly improve the welding area, improve the welding effect and ensure firm welding and sealing effect of the copper pipe inlet pipe fitting 20 and the inlet end 11.
