Abstract

The utility model discloses a cold medium liquid storage device for an air conditioner, which chiefly ccomprises a top cylinder and a bottom cylinder, wherein the top cylinder and the bottom cylinder are correspondingly provided with an aboral part in the opening form. The periphery of two aboral parts is formed into a welding part with the larger diameter to cause the two cylinder bodies to mutually involute before the welding. By a direct argon welding mode, the welding part is directly dissolved into a sealing part. The welding part is integrally welded, and the strengthened connection structure is formed outside the sealing part to cause the cylinder body not to generate the form of stress concentration. The welded whole structure is improved, and the purposes of high safety and high stability are realized.

Description

Air conditioning for automobiles refrigerant liquid reservoir

Technical field

The utility model is a kind of air conditioning for automobiles refrigerant liquid reservoir, is at employed liquid reservoir in the automotive air-conditioning system, by this structure the bulk strength of liquid reservoir is improved, to reach the purpose of high degree of safety and high anti-internal pressure.

Background technology

Automobile or the employed air-conditioning of other vehicle are in matchmaker's liquid reservoir at present, its must storage high pressure refrigerant, therefore the necessary ten minutes of the structure of its combined outside is intrepid, can be enough to resist inner compressive resistance, otherwise cause the unnecessary phenomenon that leaks outside very easily, but the design of its liquid reservoir elder generation the sky promptly has the impropriety to cause can't be certain in the seam, please cooperate shown in Figure 6, the structure of its liquid reservoir B, what have top takes blame for others 40 and the end cylinder 50 of bottom, its take blame for others 40 with end cylinder 50 in relative part mutually seam be integral, for being taken blame for others, it 40 can dock mutually with end cylinder 50, the holding part 41 that is provided with stratum's form in 40 opening parts of taking blame for others in addition is for cylinder 50 opening parts of the ccontaining end, so when herein mutually during seam, cooperate scolder to be provided with a seam portion 60 in holding part 41 outside place welderings, the structure of this seam is owing to the basic structure form of holding part 41 outsides causes the following disappearance that can't overcome itself; Such as:

1, very easily causes the disappearance of outwards destroying by inside: because the surface and the out-of-flatness of seam portion 60 inside in seam portion 60 places, promptly in the holding part 41 outside surfaces that form a height fluctuating, so unnecessary stress concentration point is very easily caused on the surface, when internal pressure increases, have the strength of outwards opening herein, seam portion 60 promptly causes the seam 61 that splits very easily thus, even the structure of the seam 61 seam portions 60 of so splitting produces destroys, and cause unnecessary leakage, so necessity of improvement is arranged.

2, the variable thickness of one-piece cylinder: for make take blame for others 40 with end cylinder 50 can be certain involutory mutually, therefore, take blame for others and 40 holding part 41 must be set, so taking blame for others 40 thickness must be greater than end cylinder 50, have nothing in common with each other in the thickness top of cylinder body, bottom, but the internal pressure of cylinder body is owing to the relation at the same space, its force value is identical, so, the end cylinder 50 of thinner thickness promptly is difficult to bear, or if the thickness of end cylinder 50 still can bear, and 40 the thickness of taking blame for others promptly shows unnecessary, cause the waste on the material, so necessity of improvement is arranged.

3, waste to some extent on the material cost: the waste on material, it is too high and the waste that causes except that described 40 thickness of taking blame for others of preceding paragraph are arranged, in addition because the mode of its welding must cooperate scolder for it, basically in the use of material, the increase of cost on the scolder is promptly arranged, and with regard on the intensity of material, because the material of this material is inevitable and original taking blame for others 40 had nothing in common with each other with the material of end cylinder 50, so, in relatively descending of structural strength, the branch of power is promptly arranged, the weak part of structure is promptly very easily destroyed by internal pressure, therefore the structure of these seam portions 60 very easily causes the inequality on the structural strength.

The utility model content

Intrepid more really for the structure that makes the liquid reservoir seam, the design of one-piece cylinder is more reasonable, and the utility model provides a kind of a kind of air conditioning for automobiles refrigerant liquid reservoir that meets above-mentioned condition.

Main purpose of the present utility model is to provide a kind of air conditioning for automobiles refrigerant liquid reservoir, be by by relative with the end cylinder weld part that protrudes that oral area place outer rim is formed of taking blame for others, and directly it is fused all-in-one-piece seam portion in when welding, make this structure form incorporate structure, and can reach the purpose of the low waste of material of high strength oral area.

This structure has following advantage, such as:

1, seam portion 30 and the one-body molded intensity height of cylinder body: since the agent structure of seam portion 30 promptly by take blame for others 10 with end cylinder 20 oral area 1121 one are extended formed flanged structure after, the all-in-one-piece structural form is fused in the row heating mutually again, its structure promptly with the cylinder body all-in-one-piece structural form of integral body, therefore the seam portion 30 after its seam there is no the general inside surfacing whether problem of knowing as usual, there is no the situation of stress concentration point, so when the internal pressure increase is outwards opened herein, the strength that its seam portion 30 can support is promptly very high, the seam 61 that splits that also unlikely generation is unnecessary is so that seam portion 30 remains best intensity and state.

2, the thickness of one-piece cylinder is identical: take blame for others and 40 only carry out involutory with plane configuration to

oral area

11,21 with end cylinder 50, therefore two involutory taking blame for others 10 can keep identical with end cylinder 20 thickness, so after forming seam portion 30, the thickness of its cylinder body integral body is suitable, so that internal pressure can be certain be evenly distributed, and reach the advantage that internal stress is on average disperseed, more make material obtain the best use that rationalizes, to save the cost on the material.

3, letter economizes on the material cost: the letter on material economizes, promptly just like the advantage of the described one-piece cylinder material thickness of preceding paragraph homogeneous, and also only being the

weld part

12,22 to

oral area

11,21 with former protrusion, the process of its welding is fused into one, it is the waste on the open, and the structure seam portion 30 that seam forms, its material matter and cylinder body are identical, and so the uniform intensity on the cylinder block material there is no the branch of power, the unlikely situation that causes stress to concentrate and destroy.
