Abstract
The utility model relates to a kind of heat exchanger tube expanded and welded tube joint clad tubesheet structures, including heat exchanger tube and clad tubesheet, clad tubesheet is combined by layers of copper and steel layer, heat exchanger tube is connected in the pore of clad tubesheet, the clad tubesheet layers of copper outer end face is equipped with the circle partition grooves concentric, circular with pore, and there are a circle boss fusion weldings to connect heat exchanger tube between partition grooves and pore.Its structure is simple, is conducive to improve welding efficiency, quality, beautifies weld seam, reduces consumptive material, reduce cost.
Description
Technical field
The utility model relates to a kind of heat exchanger apparatus, the heat exchanger tube expanded and welded tube joint of specifically a kind of shell-and-tube heat exchanger is compound
Tube plate structure.
Background technique
Traditional heat exchanger tube and clad tubesheet expanded and welded tube joint generally directly adopt argon arc welding addition welding wire and are welded, welded after welding
It is seamed into shape unsightly, undercut easily occurs and be formed in situ zigzag fashion, and since the weld seam periphery that is influenced by heat is also easy to produce minute crack,
Influence overall structure quality.
Summary of the invention
In view of the above-mentioned problems, to provide a kind of structure simple for the utility model, be conducive to improve welding efficiency, quality, beauty
Change weld seam, reduces consumptive material, reduce the heat exchanger tube expanded and welded tube joint clad tubesheet structure of cost.
The technical solution adopted in the utility model is: a kind of heat exchanger tube expanded and welded tube joint clad tubesheet structure, including heat exchanger tube and multiple
Tube sheet is closed, clad tubesheet is combined by layers of copper and steel layer, and heat exchanger tube is connected in the pore of clad tubesheet, it is characterised in that:
The clad tubesheet layers of copper outer end face is equipped with the circle partition grooves concentric, circular with pore, and there are one between partition grooves and pore
It encloses boss fusion welding and connects heat exchanger tube.
It further, is chamfering structure outside the boss inner periphery.
Still further, the clad tubesheet pore is equipped with an above seal groove of circle in the inner wall of steel layer part interlude,
Heat exchanger tube intensity is swollen to wear and connects in steel layer part interlude.
The beneficial effects of the utility model are: adding partition grooves in clad tubesheet layers of copper, clad tubesheet when welding is considered
The metal heated of surface unevenly advantageously reduces heat affected area, and partition grooves separate heat transfer, reduce heating surface, and layers of copper exists
Crackle is missed after welding;Using the boss of partition grooves inner circumferential as wlding, fusion welding connects heat exchanger tube, reduces wlding consumption, reduce at
This;Chamfering is set outside boss inner periphery, the binding force for being conducive to boss fusion welding and heat exchanger tube is stronger, welding quality is improved,
Be conducive to appearance of weld and beauty.The utility model has many advantages, such as that structure is simple, and welding efficiency is high, high-quality.
Detailed description of the invention
Fig. 1 is the utility model clad tubesheet structural schematic diagram;
Fig. 2 is the utility model heat exchanger tube expanded and welded tube joint clad tubesheet structural schematic diagram.
In figure: layers of copper 1, partition grooves 2, chamfering 3, boss 3, steel layer 4, seal groove 5, clad tubesheet 6, fillet 7, heat exchanger tube 8,
Chamfering 9.
Specific embodiment
It is described further below in conjunction with drawings and examples.
Fig. 1, shown in 2: a kind of heat exchanger tube expanded and welded tube joint clad tubesheet structure includes heat exchanger tube 8 and clad tubesheet 6, clad tubesheet 6
It is combined by layers of copper 1 and steel layer 4, heat exchanger tube 8 is connected in the pore of clad tubesheet 6, and 6 layers of copper of clad tubesheet, 1 outer end face is set
The partition grooves 2 for having a circle concentric, circular with pore, there are circle 3 fusion welding of a boss connection heat exchange between partition grooves 2 and pore
Pipe, boss inner periphery collar extension are equipped with chamfering 9, and clad tubesheet pore is equipped with a circle or more in the inner wall of steel layer part interlude and seals
Slot 5, heat exchanger tube Final 8 degree is swollen to be worn and connects in steel layer part interlude, and clad tubesheet pore is equipped with fillet 7 in steel layer collar extension, fillet
Pore mouth is convenient for the insertion of heat exchanger tube.
