Aluminum reducer pipe for refrigeration equipment
Technical Field
The utility model relates to a rate reducing pipe, especially aluminium reducing pipe for refrigeration plant.
Background
At present, more and more evaporators adopt a heat exchange pipeline structure with aluminum pipes and copper pipes, the pipeline structure is low in cost, but the connection position of the aluminum pipes and the copper pipes needs to be provided with copper-aluminum joints to realize the communication between the copper pipes and the aluminum pipes, so that the pipelines are not convenient to connect.
Disclosure of Invention
The utility model aims at providing a make things convenient for refrigeration plant of tube coupling to use aluminium reducing pipe.
Realize the utility model discloses the technical scheme of purpose as follows:
the aluminum reducer pipe for the refrigeration equipment comprises a thin pipe section, a transition section and a thick pipe section, wherein a first guide ring and a second guide ring are arranged on the inner wall of the thick pipe section, the first guide ring and the second guide ring are respectively welded and fixed with the thick pipe section, a gap is formed between the first guide ring and the second guide ring, a first brazing filler metal layer is arranged in the gap, a second brazing filler metal layer is arranged between the second guide ring and the outer port of the thick pipe section, a plurality of through holes are formed in the second guide ring, a third brazing filler metal layer connected with the first brazing filler metal layer and the second brazing filler metal layer is arranged in the through holes, the first brazing filler metal layer, the third brazing filler metal layer and the second brazing filler metal layer are of an integrated structure, and the cross section of the first brazing filler metal layer.
After adopting above-mentioned structure, thick pipeline section department sets up first guide ring and second guide ring, has made things convenient for the copper pipe to insert in the thick pipeline section, forms the support to the copper pipe simultaneously, has made things convenient for the insertion of copper pipe, and first brazing filler metal layer, third brazing filler metal layer and second brazing filler metal layer can realize brazing of thick pipeline section and copper pipe fixed, and the structure of first brazing filler metal layer, third brazing filler metal layer and second brazing filler metal layer has improved the joint strength between thick pipeline section and the copper pipe simultaneously, the utility model discloses a do not need copper aluminium to connect also can be connected between aluminum pipe and the copper pipe, simple to operate, structural strength is high simultaneously, is difficult for receiving vibration or external force influence and damaging.
Preferably, in order to avoid the second brazing filler metal layer from falling off due to the influence of external force, an annular positioning block is fixed at the outer port of the thick pipe section, and a protective sleeve is sleeved on the annular positioning block.
Preferably, in order to improve the structural strength of the aluminum-variable reducer pipe, the outer walls of the thin pipe sections and the transition sections are provided with a plurality of strip-shaped reinforcing ribs.
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.
In the figure: 1 is the tubule section, 2 is the changeover portion, 3 is thick pipeline section, 4 is first guide ring, 5 is the second guide ring, 6 is the clearance, 7 is first brazing filler metal layer, 8 is the second brazing filler metal layer, 9 is the through-hole, 10 is the third brazing filler metal layer, 11 is annular locating piece, 12 is the protective sheath, 13 is the bar strengthening rib, 14 is the copper pipe.
