Abstract
The thin-walled small-diameter aluminium alloy pipe plumb joint structure that the utility model provides, two soldered aluminium-alloy pipe [1] end overcoats have an aluminium-alloy pipe adapter sleeve [2], and aluminium-alloy pipe adapter sleeve two ends are welded with aluminium-alloy pipe respectively.The thin-walled small-diameter aluminium alloy pipe plumb joint structure that the utility model provides, overlap an aluminium-alloy pipe adapter sleeve outward at the joint for pipe of docking, and directly weld with two tube outer walls that will dock at its two ends, its effect is equivalent to the roll line connection having had lining.Compared with prior art, the utility model only needs to prepare aluminium-alloy pipe adapter sleeve and just can construct at the scene, convenient and reliable, more can not occur the joint affecting flow regime on coolant channel.
Description
Technical field
The utility model relates to a kind of thin-walled small-diameter aluminium alloy pipe plumb joint structure.
Background technology
For reducing the cost of freezer construction and improving refrigerating efficiency, the thin-wall aluminum alloy pipe of the band of freezer evaporimeter extensive use now radiating fin, but thin-wall aluminum alloy pipe can cause tube wall to subside when docking welding, serious meeting causes perforation, and butt-welded connection fastness is also not enough.Therefore someone proposes welding after pipe end makes roll line socket, but still has and subside and be connected unstable phenomenon.For stopping the generation of subsiding, Chinese invention patent ZL200410084415.8 " thin-walled small-diameter aluminium alloy pipe joint structure and welding and welding method thereof " is had to describe a kind of plumb joint structure serving as a contrast a copper pipe in pipe end junction again.But this plumb joint structure going back roll line, inherently has cost of manufacture higher and be not suitable for the defect of site operation, more within it serve as a contrast and both added working procedure with copper sheathing, again in the little pipe inner passage section of this place limit, flow and fluid state are affected.
Summary of the invention
The utility model is exactly to provide a kind of thin-walled small-diameter aluminium alloy pipe plumb joint structure at the additional cover of pipe.
The thin-walled small-diameter aluminium alloy pipe plumb joint structure that the utility model provides, two soldered aluminium alloy pipe end overcoats have an aluminium-alloy pipe adapter sleeve, and aluminium-alloy pipe adapter sleeve two ends are welded with aluminium-alloy pipe respectively.
The thin-walled small-diameter aluminium alloy pipe plumb joint structure that the utility model provides, overlap an aluminium-alloy pipe adapter sleeve outward at the joint for pipe of docking, and directly weld with two tube outer walls that will dock at its two ends, its effect is equivalent to the roll line connection having had lining.Compared with prior art, the utility model only needs to prepare aluminium-alloy pipe adapter sleeve and just can construct at the scene, convenient and reliable, more can not occur the joint affecting flow regime on coolant channel.
Thin-walled small-diameter aluminium alloy pipe plumb joint that the utility model provides structure, have radiating fin outside described aluminium alloy tube wall, the outer wall that aluminium-alloy pipe is inserted in aluminium-alloy pipe adapter sleeve part is smooth, and smooth section is greater than and is inserted in part void.
The thin-walled small-diameter aluminium alloy pipe plumb joint structure that the utility model provides, radiating fin is had outside the wall of described aluminium-alloy pipe and aluminium-alloy pipe adapter sleeve, wherein aluminium-alloy pipe is inserted in the outer wall of aluminium-alloy pipe adapter sleeve part is smooth, and smooth section is greater than and is inserted in part void.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model one embodiment, and Fig. 2 is A in Fig. 1---A to sectional view, in figure: 1-aluminium-alloy pipe, 2-aluminium-alloy pipe adapter sleeve, a-radiating fin;
Fig. 3 is the structural representation of the utility model one embodiment, and Fig. 4 is B in Fig. 3---B to sectional view, in figure: 3-aluminium-alloy pipe two, 4-aluminium-alloy pipe adapter sleeve two, b-radiating fin two, c-adapter sleeve radiating fin.
Detailed description of the invention
1, as shown in Figure 1, 2, two aluminium-alloy pipes 1, dock with straight port, pipe is outer radiating fin a, one section of radiating fin is removed at joint, be socketed with aluminium-alloy pipe adapter sleeve 2 outside it, after socket, Shang Yuyi is greater than the gap of welding requisite space, is directly that sleeve pipe two ends are welded with aluminium-alloy pipe by solder with sleeve end.
2, as shown in Figure 3,4, two aluminium-alloy pipes 23, dock with straight port, pipe is outer radiating fin two b, removes one section of radiating fin at joint, is socketed outside it with aluminium-alloy pipe adapter sleeve 24, after socket, Shang Yuyi is greater than the gap of welding requisite space, have adapter sleeve radiating fin two c outside aluminium-alloy pipe adapter sleeve, adapter sleeve radiating fin two is the same with the outer radiating fin two of aluminium-alloy pipe, is directly that sleeve pipe two ends are welded with aluminium-alloy pipe by solder with sleeve end.
