Description
Technical Field
The utility model relates to a copper aluminum joint, in particular to a copper aluminum joint with stable connection.
Background
The pipeline of heat exchanger generally adopts the copper pipe, however because of cost reason, more and more heat exchangers adopt the aluminum pipe now on some pipelines, therefore need adopt copper aluminium to connect usually to realize the connection of different material pipelines at the junction of copper pipe and aluminum pipe, however current copper aluminium joint design is too simple, copper pipe and simple welded connection of aluminum pipe junction, joint strength is low, especially the copper aluminium union coupling department of copper aluminium joint is easy to break under the radial condition that receives external force, poor stability.
Disclosure of Invention
The utility model aims at providing a stable connection copper aluminium joint that joint strength is high, difficult disconnection.
Realize the utility model discloses the technical scheme of purpose as follows:
connect stable copper aluminium and connect, including copper pipe and aluminum pipe, the tip of copper pipe is equipped with first annular step, the tip of aluminum pipe is equipped with second annular step and third annular step, second annular step adjusts direct formation with the third annular and supplies annular step male slot, first annular step is equipped with the first through-hole of multiunit, second annular step is equipped with the second through-hole of multiunit respectively with first through-hole one-to-one, be equipped with the third through-hole of multiunit respectively with first through-hole one-to-one on the third annular step, set up the brazing filler metal layer in first through-hole, second through-hole and the third through-hole, copper pipe and aluminum pipe are through brazing filler metal layer fixed connection, and the junction cover of the outer wall of copper pipe and aluminum pipe is equipped with the pyrocondensation pipe.
After the structure is adopted, the first annular step, the second annular step and the third annular step are fixedly connected through brazing of the brazing filler metal layer, the connection strength of the copper pipe and the aluminum pipe is improved, the connection part of the copper pipe and the aluminum pipe is not prone to being broken under the condition that external force is applied, and the stability of the copper-aluminum joint is improved.
Preferably, in order to improve the connection strength of the first annular step, the second annular step and the third annular step, grooves are formed in the inner wall and the outer wall of the first annular step, the grooves are communicated with the first through holes, and a brazing filler metal layer is arranged in the grooves in the same way.
Preferably, in order to improve the connection strength of the first annular step, the second annular step and the third annular step, two first through holes, two second through holes and two third through holes are arranged in each group, a connecting hole is arranged between the two third through holes in the same group for communication, the first through holes, the second through holes, the third through holes and the connecting holes form a U shape, and a brazing filler metal layer is also arranged in the connecting holes.
Drawings
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a schematic view of a connection structure of the first annular step, the second annular step and the third annular step of the present invention.
In the figure: the heat-shrinkable tube comprises a copper tube 1, an aluminum tube 2, a first annular step 3, a second annular step 4, a third annular step 5, an insertion groove 6, a first through hole 7, a second through hole 8, a third through hole 9, a brazing filler metal layer 10, a heat-shrinkable tube 11, a groove 12 and a connecting hole 13.
