Below, based on accompanying drawing embodiments of the present invention are described.
Figure 10 is for example as the refrigeration cycle structure figure of the refrigerating circulatory device of air conditioner.
Among the figure, symbol 1 is a compressor, and its cold-producing medium with suction is compressed into the gas refrigerant of HTHP, and discharges to coolant conduits P.Compressor 1 is communicated with condenser 2 via this coolant conduits P, thereby will guide the gas refrigerant that comes to be condensed into liquid refrigerant.
Above-mentioned condenser 2 is communicated with expansion valve 3 as expansion gear via coolant conduits P, so that the liquid refrigerant adiabatic expansion that guiding comes.And expansion valve 3 is communicated with evaporimeter 4 via coolant conduits P, thereby makes cold-producing medium evaporation, and captures the evaporation latent heat of this moment and become cold air from heat exchange air.That is, played freezing (refrigeration) effect.
Above-mentioned evaporimeter 4 is communicated with storage tank 5 via coolant conduits P, thereby will guide next vaporized refrigerant gas-liquid separation.Have only isolated gas refrigerant to be inhaled into compressor 1, repeat above-mentioned kind of refrigeration cycle once more via coolant conduits P.By storage tank 5 is set, compressor 1 just can the inhalant liquid cryogen, can prevent that thus hydraulic pressure from contracting.
In addition, also use not shown oil eliminator and fluid box (liquid tank) etc. in the above-mentioned kind of refrigeration cycle, they are collectively referred to as " kind of refrigeration cycle container R " with above-mentioned storage tank 5.Below, the connected structure of kind of refrigeration cycle with container R and coolant conduits P described.
Fig. 1 is the front view of the kind of refrigeration cycle of first embodiment with container Ra.
This kind of refrigeration cycle comprises with container Ra: container body 10, and this container body 10 has separating plate 10a in inside; The first coolant conduits P1, this first coolant conduits P1 engages with container body 10 upper ends; The second coolant conduits P2, the end of this second coolant conduits P2 engages with the bottom surface sections of container body 10, and the other end erects formation in container body 10 inside; And the 3rd coolant conduits P3, the end of the 3rd coolant conduits P3 engages with the second coolant conduits P2 via the bottom surface sections of container body 10, and the other end becomes roughly U word shape in the outer bend of container body 10.
On refrigeration cycle structure, the first coolant conduits P1 is connected with above-mentioned evaporimeter 4, and at this, the cold-producing medium after the evaporation is directed in the container body 10 via the first coolant conduits P1.Be provided with separating plate 10a in container body 10 inside relative, vaporized refrigerant is flow through, thus it is separated into gas refrigerant and liquid refrigerant with the openend of the first coolant conduits P1.
Liquid refrigerant accumulates in the bottom in the container body 10, and gas refrigerant is inhaled into and is directed to the 3rd coolant conduits P3 from the openend of the second coolant conduits P2, is inhaled into compressor 1 then and compresses.The liquid refrigerant that accumulates in the bottom in the container body 10 is passed in time or is subjected to the temperature effect of extraneous air and evaporates, and becomes gas refrigerant thus and is inhaled into from the openend of the second coolant conduits P2.
The structure of kind of refrigeration cycle with container Ra described, said vesse main body 10 comprises again: lens barrel 11 cylindraceous, and the upper and lower end parts opening of this lens barrel 11, and embed in the upper end separating plate 10a is arranged; Top cover plate 12, this top cover plate 12 are welded into the upper end open portion of the above-mentioned lens barrel 11 of sealing; And bottom cover plate 13, this bottom cover plate 13 is welded into the lower ending opening portion of the above-mentioned lens barrel 11 of sealing.
In addition, on the side face of bottom cover plate 13 by welding processing across predetermined distance a plurality of support foots 14 are installed.The component parts of this container body 10 all adopts ironwork, comprises that the whole peripheral surface of support foot 14 has been carried out application.
The first coolant conduits P1 uses steel pipe.The connected structure of the top cover plate 12 of the first coolant conduits P1 and formation container body 10 as shown in Figure 2.
Central part at top cover plate 12 is provided with erection opening H, and the bottom of the first coolant conduits P1 is inserted into wherein, is kept temporarily.In addition, under this state, the side face of the first coolant conduits P1 and the perimembranous of erection opening H are carried out the processing of MIG solder brazing Y.
Because the scolder that uses in MIG solder brazing Y is main component with copper, and makes scolder self become electrode, therefore, is also referred to as " arc-welding of consumption of electrode formula ".That is, " arc-welding of consumption of electrode formula " is to utilize arc heat to carry out the method for soldering, and it has distortion that occurs because of local heat or the characteristics that pore is less and process velocity is fast.
Being processed into kind of refrigeration cycle is when top cover plate 12 is in independent state with top cover plate 12 before lens barrel 11 engages with the processing sequence of container Ra, utilizes MIG solder brazing Y that the first coolant conduits P1 is engaged with top cover plate 12.
The second coolant conduits P2 also can be an iron pipe, but the 3rd coolant conduits P3 uses copper pipe.When bottom cover plate 13 is in independent state with bottom cover plate 13 before lens barrel 11 engages, utilize MIG solder brazing Y that the second coolant conduits P2 and the 3rd coolant conduits P3 are engaged with bottom cover plate 13.
In more detail, at first, utilize MIG solder brazing Y that the second coolant conduits P2 is engaged with bottom cover plate 13, after this, against junction surface, and utilize MIG solder brazing Y to engage the end of the 3rd coolant conduits P3 to the bottom cover plate 13 and the second coolant conduits P2 end.
In addition, will engage the upper end of top cover plate 12 welding processing of the first coolant conduits P1, thereby the upper end open portion of lens barrel 11 has been sealed to lens barrel 11.Then, will engage the bottom of bottom cover plate 13 welding processing of the second coolant conduits P2 and the 3rd coolant conduits P3, thereby the lower ending opening portion of lens barrel 11 has been sealed to lens barrel 11.Thus, finish the assembling of container body 10.
For example, when the first coolant conduits P1 is connected with top cover plate 12, attempt the existing situation of silver brazing of carrying out is compared with the situation of carrying out MIG solder brazing Y that illustrates in the present invention.
Engaging on the process time that a place needs, adopt silver brazing to need about 40 seconds, and adopt MIG solder brazing Y to need only about 10 seconds.On the cost of scolder, the silver solder per kilogram is 20,000 7 thousand yen (during applications), and the spelter solder per kilogram that uses among the MIG solder brazing Y 5,000 yen (during applications) just can have been bought.
On actual job, silver brazing has to carry out operation by operator's (craft), and MIG solder brazing Y can easily carry out automation.In addition, silver brazing needs solder flux and hot water injection's treatment process as preceding post-processed, and MIG solder brazing Y does not need to carry out preceding post-processed.
Like this, MIG solder brazing Y compares with silver brazing has a lot of favourable parts, therefore, can realize the labour that minimizing container body 10 and engaging of coolant conduits P1～P3 are required and shorten process time, thereby help reducing cost.
Fig. 3 A, Fig. 3 B, Fig. 3 C be the explanation top cover plate 12 that constitutes container body 11 manufacturing sequence and with the figure that engages of the first coolant conduits P1.Though do not illustrate especially, bottom cover plate 13 is also identical with the joint of the second coolant conduits P2.
At first, as shown in Figure 3A, prepare to overlook and observe rectangular plate body D, and erection opening H is set at the central part of plate body D.Then, shown in Fig. 3 B, the rectangle plate body D that central part is provided with erection opening H is formed the cross section semicircular in shape by pull and stretch processing.Alignd on same position in all ends, form roughly bowl-shape top cover plate 12 thus.
Shown in Fig. 3 C, the cross section of the previous erection opening H that is provided with is the outer surface side diameter taper bigger than inner surface side diameter of top cover plate 12.This is the cross sectional shape that must form by the rectangle plate body D with regulation thickness of slab being carried out pull and stretch processing, after inserting the first coolant conduits P1, its with the erection opening H periphery of the outer surface side of top cover plate 12 between generation gap to a certain degree.
That is,, also can be processed to form roughly bowl-shape top cover plate 12, and make that the cross section of erection opening H is tapered owing to rectangle plate body D is carried out pull and stretch even the diameter erection opening H identical with the diameter of the first coolant conduits P1 is set in the rectangle plate body D stage.
After the first coolant conduits P1 is inserted erection opening H, between the coolant conduits P1 of the outer surface side of top cover plate 12 and erection opening H periphery, can form enough tangible gap.The scolder of MIG solder brazing Y enters above-mentioned gap easily, thereby makes the bond strength of the top cover plate 12 and the first coolant conduits P1 become big.
In addition, in the above-described embodiment, all select for use the situation of ironwork to be illustrated to the lens barrel 11 that constitutes container body 10 and top cover plate 12 and bottom cover plate 13, but be not limited to this.
By using the component parts of highly corrosion resistant clad steel sheet as container body 10, thus, not only do not need to carry out external coating, can also obtain good rust-proof effect.Also not a halfpenny the worse on intensity, simultaneously to cost also not influence.
In addition, will engage with said vesse main body 10 by coolant conduits P1～P3 that copper pipe is made by MIG solder brazing Y.Use with copper constantly as this point of scolder, just each coolant conduits P1～P3 can be engaged with container body 10 securely as the material of main component.
Fig. 4 is the front view of the kind of refrigeration cycle of second embodiment with container Rb.Container body 10 is with before different on total height and diameter at container body illustrated in fig. 1, but since structurally identical, thereby omit its special instruction.
Coolant conduits comprises: two connection coolant conduits P4, P5, and these two connections are outstanding towards top from the top cover plate 12 that constitutes container body 10 with coolant conduits P4, P5; And U font coolant conduits P6, this U font coolant conduits P6 connects with above-mentioned the connection with coolant conduits P4, P5 by top cover plate 12 by MIG solder brazing Y, and is housed in container body 10 inside.
At this, use copper pipe to connect, and U font coolant conduits P6 uses iron pipe to be feature with coolant conduits P4, P5.That is, be copper product from container body 10 with the outside coolant conduits that is connected, be ironworks identical and be housed in container body 10 interior U font conduit P6 with container body 10.
Though have only U font coolant conduits P6 to use ironwork, get rusty because this coolant conduits P6 is housed in container body 10 inside and does not contact with extraneous air, thereby be difficult for.By using cheap ironwork, can help cost and reduce.Certainly, can not bring influence on any performance to kind of refrigeration cycle with container Rb yet.
Two coolant conduits P engage in order to incite somebody to action up and down by container body 10, use such connected structure shown in Fig. 5 A or Fig. 5 B.
In Fig. 5 A, erection opening H is inserted from the top of container body 10 in the end of the upper side coolant conduits Pa that will be made by copper pipe.Then, by MIG solder brazing Y upper side coolant conduits Pa is engaged with the container body of being made by ironwork 10.Owing to use with copper to the material of main component as scolder, thereby can obtain firm joint at short notice.
After this, propping up the openend of the lower side coolant conduits Pb that makes by iron pipe from the lower side of container body 10 mode relative, and lower side coolant conduits Pb is engaged with container body 10 by welding U with erection opening H.
Like this, engaging operation and become two stages, but owing to can guarantee air-tightness by using MIG solder brazing Y, therefore, is that lower side coolant conduits Pb carries out common welding processing U with the container body of being made by ironwork 10 and gets final product to iron pipe.Because container body 10 inside of finishing do not have oxygen, therefore, lower side coolant conduits Pb is difficult for getting rusty.
Fig. 5 B represents other example of connected structure.
The open end of lower side coolant conduits Pd is inserted erection opening H from the bottom of container body 10, and make its upper surface side outstanding to a certain degree towards container body 10.This state of interim maintenance makes the openend of upper side coolant conduits Pc relative with the openend of lower side coolant conduits Pd from the top of container body 10.
Then, simultaneously MIG solder brazing Y is carried out in container body 10, upper side coolant conduits Pc end and lower side coolant conduits Pd end.Engage operation and need only a stage, Y just can guarantee air-tightness by MIG solder brazing.In addition, the lower side coolant conduits Pd of container body 10 inside is difficult for getting rusty, and this puts constant.
Fig. 6 represents the horizontal kind of refrigeration cycle container Rc as third embodiment of the invention.
Kind of refrigeration cycle herein is with among the container Rc, and the axial of container body 10A of putting along quilt engages many (two) coolant conduits P each other by MIG solder brazing Y at least across L ground, interval.Above-mentioned interval L must be set at more than about 150mm.
That is, but MIG solder brazing Y automation carry out this point with above-mentioned be identical.Specifically, need to keep the welding torch of scolder, on one side this welding torch is moved around coolant conduits P, carry out MIG solder brazing Y on one side.
Therefore, when after first coolant conduits P carried out MIG solder brazing Y, second coolant conduits P being carried out MIG solder brazing Y, if first coolant conduits P and second coolant conduits P are in the position that is close, then can't carry out the MIG solder brazing Y of second coolant conduits P.
By as mentioned above coolant conduits P interval L each other being increased to more than about 150mm, just can avoid when carrying out the MIG solder brazing Y of second coolant conduits P interference, thereby can realize clog-free processing welding torch.
Fig. 7 is the front view of the kind of refrigeration cycle of four embodiment of the invention with container.
It is also constant herein by MIG solder brazing Y coolant conduits P to be engaged this point with container body 10B.
In addition, said vesse main body 10 is directly carried out welding processing by top cover plate 12 and bottom cover plate 13 and is engaged and form.That is, do not use the lens barrel 11 shown in Fig. 1 to constitute container body 10B, even but lens barrel 11 is located at do not have any influence between top cover plate 12 and the bottom cover plate 13 yet.
Crucial being characterised in that at the junction surface coiling stainless steel wire (SUS line) 15 of the top cover plate 12 that constitutes container body 10B with bottom cover plate 13, and carried out welding processing from this stainless steel wire 15.
In common welding processing, after this, need carry out application, but after long-term the use, in most cases can get rusty container body 10B.Therefore, repair application, not only require great effort, and also have hidden danger on the effect for the application that thickens welding portion.
Therefore, after as mentioned above stainless steel wire 15 being wound to the junction surface, carry out welding processing.By this, the stainless steel material that the bonding part is had rust-proof effect covers, and does not need at least application is repaired in the bonding part.
Fig. 8 A, Fig. 8 B are the figure of the joint method of explanation fifth embodiment of the invention, and Fig. 8 A is the cutaway view of top cover plate 12, and Fig. 8 B is its vertical view.
When coolant conduits P was machined to top cover plate 12 by MIG solder brazing Y, when the beginning operation, top cover plate 12 all was a normal temperature with coolant conduits P, owing to do not improve temperature, therefore, was difficult for engaging.If finish with incomplete joint, then refrigerant gas is easily from this part leakage, and lacks reliability.
Therefore, when the operation of beginning MIG solder brazing Y, the part that scolder is propped up the side face certain distance that leaves coolant conduits P heats.Just carry out so-called preheating, and wait for that the temperature of top cover plate 12 rises.
With this state continuance stipulated time, and make after the temperature of the erection opening H periphery of top cover plate 12 fully rises, carry out MIG solder brazing Y, can realize engaging reliably of coolant conduits P and top cover plate 12 thus by side face to coolant conduits P.
Fig. 9 A, Fig. 9 B are the figure of the joint method of explanation sixth embodiment of the invention, and Fig. 9 A is the vertical view of bottom cover plate 13, and Fig. 9 B is a cutaway view.
When the erection opening H of bottom cover plate 13 is located in the open end insertion of coolant conduits P, make the inner surface side outstanding certain distance of the open end of coolant conduits P towards bottom cover plate 13.This state of interim maintenance will carry out MIG solder brazing Y from open end side face and the bottom cover plate 13 of the outstanding coolant conduits P of the inner surface side of bottom cover plate 13, thus bottom cover plate 13 be engaged with coolant conduits P.
If can confirm the result of leak test is that bottom cover plate 13 does not leak with the place, junction surface of coolant conduits P, just no problem.When confirming to exist when leaking, then to carry out MIG solder brazing Y to the side face of coolant conduits P and repair from the outer surface side of bottom cover plate 13 at above-mentioned junction surface.
That is,, also to consider in leak test, to find to have the situation of leakage after the outer surface side of bottom cover plate 13 and coolant conduits P carry out MIG solder brazing Y as common manufacturing process.At this moment, scolder after soldering has been arranged in the outer surface side of bottom cover plate 13, even it is after this repair the MIG solder brazing Y of usefulness, also relatively poor on the effect.
If from the inner surface side of bottom cover plate 13 coolant conduits P is carried out MIG solder brazing Y in advance as mentioned above, even in leak test, find to have leakage, owing to do not carry out any processing in the outer surface side of bottom cover plate 13, and therefore, can repair easily and reliably.
In addition, in being engaged to the coolant conduits P of bottom cover plate 13, if along the length long enough of its axial linearity part, as long as be flexed into roughly L font therefrom, from the outer surface side of bottom cover plate 13 coolant conduits P being carried out MIG solder brazing Y just can be so not difficult.
Yet, also have along the length of the axial linearity part of the coolant conduits P that is engaged to bottom cover plate 13 very shortly, not have to be flexed into the roughly situation of L font under the state at abundant interval with bottom cover plate 13.
At this moment, carrying out perfect MIG solder brazing Y from the outer surface side of bottom cover plate 13 is difficult eventually.Therefore, preferably can carry out perfect MIG solder brazing Y and defective (NG) can leak test, not occur from the inner surface side of bottom cover plate 13.
In sum, for container body and coolant conduits are carried out MIG solder brazing, use the scolder of copper-aluminium class as the scolder of wire rod.
As scolder, also there is the scolder of copper-silicon class, but in case actual the use, the hole can occur or break in the solder brazing part, and can't guarantee airtight construction.Experimental result is if use copper-aluminium class (aluminium bronze), then can engage without a doubt.
In addition, the present invention is not limited to above-mentioned embodiment, the implementation phase can be in the scope that does not break away from its purport inscape distortion back be specialized.And, can form various inventions by the appropriate combination of the disclosed a plurality of inscapes of above-mentioned embodiment.
Industrial utilizability
