Description

Novel brazing pipeline structure

Technical Field

The utility model relates to the technical field of welding, in particular to a novel brazing pipeline structure.

Background

Along with the increasing shortage of traditional energy sources, the application of solar energy is more and more widespread, and especially the application of solar water heaters is more and more popular, wherein the plate-type solar water heater is favored by more and more consumers due to the advantages of simple structure, safe and convenient use and the like, and the heat collecting plate is a main component of the plate-type solar water heater, and the quantity and thickness of the arranged pipelines influence the heat absorption and heat exchange effects during use;

the material of the pipeline of common plate solar water heater heat collecting plate is mainly red copper material or silver titanium tubular product matter, and main water inlet and outlet pipeline and branch pipe pipeline adopt the welding mode to connect generally, but because the pipe wall of main water inlet and outlet pipeline and branch pipe pipeline is thinner, deformation or formation leak point easily causes the infirm condition of welding when welding.

Disclosure of Invention

The technical problem to be solved by the utility model is to overcome the defects of the technology and provide a novel brazing pipeline structure.

In order to solve the technical problems, the technical scheme provided by the utility model is a novel brazing pipeline structure, which comprises a main pipe and branch pipes, wherein a plurality of welding holes are formed in the main pipe, the branch pipes are inserted into the main pipe through the welding holes, the branch pipes are mutually perpendicular to the main pipe, and the lower ends of the main pipe and the branch pipes are connected through brazing.

Further, the welding open hole is of an inwards concave elliptic structure, and two openings are respectively formed in the front side and the rear side of the welding open hole along the extension direction of the main pipe.

Further, the branch pipe is a buckling pipe formed by a first pipe fitting and a second pipe fitting, a cavity is formed in the first pipe fitting, and the second pipe fitting is buckled in the cavity of the first pipe fitting.

Further, the outer diameter of the second tube is smaller than the inner diameter of the first tube.

Further, the brazing welding is specifically flame or high-frequency heater heating brazing.

Compared with the prior art, the utility model has the advantages that: the device has reasonable structural design, the branch pipe is formed by buckling the first pipe fitting and the second pipe fitting, the branch pipe is roughened by buckling and pressing and is provided with the convex root, the adhesive suction effect on the hot-melt brazing material is better, and the welding is firmer than the traditional smooth pipe welding; the welding trompil has been seted up on being responsible for, and the welding trompil has seted up two openings respectively in the front and back both sides along being responsible for extending direction, and when welding, the hot melt filler is fuller, and the welding is more firm than traditional welding.
