Description
The present invention relates to the installation in an evaporator plate inner capillary tube road, an instrument that is suitable for this purpose and an evaporator plate that uses described method and/or tool production.
Being used for the evaporator plate of refrigeration plant, particularly so-called cold wall evaporimeter produces by traditional mode.Wherein the thin plate plane earth of two varying strengths interfixes, and wherein that of certain described thin plate position that should form the evaporator refrigerant pipeline keeps not connecting.By a kind of fluid being pressed between described two flat boards, described unconnected zone struts mutually, and so refrigerant tubing is opened, wherein because the varying strength of described two thin plates makes the bigger shape that in fact remains unchanged of intensity in these two thin plates.It is smooth that described stronger thin plate keeps, and this practicality for evaporimeter has very big meaning, because must be bonded in outwardly on the lateral surface of storage in the refrigeration plant entirely in order to reach this thin plate of effective refrigeration.The out-of-flatness of thin plate will cause including air chamber between it and interior storage.This air chamber will hinder the heat exchange between refrigeration plant inner chamber and the evaporimeter, and therefore causes the higher power consumption of refrigeration plant.
On evaporimeter, a supply line that is used for cold-producing medium must be connected with a discharge tube.Traditionally, supply line is a capillary channel, it before entering evaporimeter in the inner guiding of discharge tube, so that by making the cold-producing medium of the liquefaction of in capillary channel, carrying realize pre-cooled with thermo-contact that be output, vaporized cold-producing medium.In order to connect this two pipelines, on an evaporimeter 1 shown in the perspective view of Fig. 1, be provided with a connecting pipe section 2 usually, it comes out to extend to the inside of evaporimeter 1 from a side, and its cross section is so definite, makes that face injects a discharge tube 4 and closely fixing hermetically here.On the end of the inside of connecting pipe section 2, on the extendible portion of straight line, be connected with the part 3 that a taper is shunk, this contraction carries out the transition to a capillary channel passage 6 at last, the cross section of this capillary channel passage be suitable for injecting therein one by discharge tube 4 guiding capillary supply line 7 and fix.At the end away from capillary channel passage 6, the cross section of the refrigerant tubing 5 of evaporimeter 1 extends again.This refrigerant tubing extends on the whole surface of evaporimeter agley, can be combined in again on the connecting pipe section 2 of leading on tapered segment 3 passages at last.
By being pressed into the inside span width that fluid can not reach connecting pipe section 2 and capillary channel passage 6, this width is necessary for inserting discharge tube 4 or supply line 7 individually.In order to reach this necessary inside span width, insert well-known expansion plug, it is pushed in the connecting pipe section 2 from the outside, so that expand this connecting pipe section or capillary channel passage 6 on desirable cross section.
In traditional expansion plug, can not get rid of the distortion of the bigger flat board 8 of intensity in two flat boards 8,9 that described expansion also causes evaporimeter 1.The consequence of such distortion is that evaporimeter 1 no longer can be bonded on the interior storage of refrigeration plant whole plane, must avoid this situation.Because this uses traditional expansion plug successfully not reach reliably, in traditional approach, before expansion, earlier a pit mold pressing is worked in the bigger flat board 8 of intensity on the position of connecting pipe section 2 and capillary channel passage 6, the degree of depth of this pit is typically about 0.8mm, and the projection of therefore bigger than the intensity of being expected when expanding connecting pipe section 2 or capillary channel passage 6 flat board 8 is bigger.Guaranteed that so described projection is no more than the part that is not molded on dull and stereotyped 8 surface, although therefore so that distortion is arranged, yet dull and stereotyped 8 is that whole plane ground is cohesible to the full extent.
Adopt this technology, though reach effective heat exchange in the inside of evaporimeter and refrigeration plant, this technology is because other do not expected former thereby do not prove fully gratifying technology.Same also because this opens wide towards the edge by remaining after evaporimeter is bonding usually at the pit that mold pressing produced on the evaporimeter, so moisture can enter this pit and condensation inside.Moisture will freeze when evaporator operation, and the ice that is produced at this moment struts evaporimeter storage in the refrigeration plant.Enlarged the volume that moisture can enter in this way.During operation, this finally can cause evaporimeter to come off from interior storage in large area, and therefore can cause relatively poor refrigerating efficiency.
Another problem when connecting pipe section 32 and capillary channel passage 6 are carried out reaming is to have the danger that damages, and for example in two flat boards 8,9 damages with the form that penetrates, and this damage will make whole evaporimeter not use.
Perhaps the burr that is produced when reaming hinders flowing of cold-producing medium and causes undesirable noise.
Task of the present invention is to provide a kind of method, a kind of instrument and evaporator plate that is used for this purpose that is used for installing capillary channel in an evaporimeter.Can so that on the bigger flat board of the intensity of evaporimeter, may hinder in flat board and the refrigeration plant degree thermo-contact between the storage, out-of-flatness to reach minimum, when mounted defect rate and when evaporimeter move noise produce and reach minimum.
A kind of method of the feature of this task by having claim 1, a kind of instrument of feature with claim 11 and a kind of evaporator plate with feature of claim 14 are finished.
When inserting plug, one first flat board of its flat side and evaporimeter contacts, the power that is acted on when can be implemented in insertion is like this passed through the whole surface distributed of this flat side on first flat board, and the mask of masterpiece being used on second flat board thereon has minimum width.The pressure that acts on the contact-making surface of expander tool and described second flat board is bigger than the pressure on the contact-making surface that acts on first flat board actually here, so that the distortion that is produced on first flat board is insignificant.
Can insert two different instruments, they are inserted into successively and are drawn out again, so that expansion connecting pipe section cross section and capillary channel passage.The order that described in this case instrument inserts is arbitrarily.
Particularly also can expand connecting pipe section cross section and capillary channel passage simultaneously by means of the instrument of a combination.A kind of like this instrument can be an one, and it has second plug that sends from the first plug top.
In a preferred scheme of instrument, second plug is slidably in the passage of first plug.This can at first expand connecting pipe section cross section with such instrument, under the situation of not pulling out first plug passage of second plug by described first plug is inserted in the capillary channel passage then.The passage of first plug has guaranteed the accurate guiding of second plug in this case, and the danger that this guiding fractures second plug minimizes, described formation and the dull and stereotyped destruction that fractures and can cause too much distortion, burr.
Carry out mold pressing processing, preferably roll die and die carries out by means of a pair of for the capillary channel passage that wherein is inserted with capillary channel, wherein die is pressed two chase forms the flat board that enters into evaporimeter in the both sides of capillary channel.
Carry out described mold pressing processing under heat and/or the action of ultrasonic waves in order between capillary channel and evaporimeter, to set up the connection that material merges, to be preferably in.
Other features and advantages of the present invention with reference to accompanying drawing from following for the description of embodiment draw.Accompanying drawing illustrates:
That Fig. 1 had discussed, a perspective view with evaporator plate of the bonding pipeline of reeling;
One group of perspective view that is used on the evaporimeter of Fig. 1, installing the expander tool of capillary channel and discharge tube of Fig. 2;
One of Fig. 3 has the expander tool of combination integrally;
One of Fig. 4 has each other the slidably expander tool of the combination of plug;
Fig. 5 by the capillary channel passage area of the evaporimeter of the processing that is molded and by being used to carry out a constructed profile that rolls a die and a die of mold pressing processing;
The perspective view of a vicissitudinous expander tool of Fig. 6;
The profile of the connecting portion of the evaporator plate that one of Fig. 7 goes out by the tool processes of using among Fig. 6.
Fig. 2 has shown one group of perspective view with expander tool of plug 11 and 12.These two plugs can be inserted in the capillary channel passage of a connecting pipe section cross section or an evaporator plate, so that expand described passage, are used to hold discharge tube or capillary channel.
Fig. 3 has shown the expander tool of a combination, can be understood as being rigidly connected of these two plugs 11 and 12, and the second wherein narrower plug 12 sends from the top of broader plug along the equidirectional of broad plug and extends.This instrument allows connecting pipe section 2 and capillary channel passage 6 to expand at an in-process.The length of the length of second plug 12 and connecting pipe section determines whether the time at first to carry out the expansion of capillary channel 6 in expansion, at first carry out the expansion of connecting pipe section 2 or the two is expanded simultaneously.
That expander tool with the combination shown in the perspective view in Fig. 4 comprises a set interior plug 12 of capillary channel passage that is used to expand evaporator plate, and plug is bootable slip outside in the passage 13 of plug 11 in this.
The details of plug 11,12 also with the same realization the in Fig. 2 and 3 embodiment, illustrates with identical Reference numeral in Fig. 4, no longer is repeated in this description.Interior plug 12 is the interior guiding of a boring of plug 11 outside, and 17 places carry out the transition to the passage 13 that an edge opens wide in the side in this boring.The side 17 of the side 15 of interior plug 12 plug 11 in this passage 13 and outside having is positioned at a plane.
For discharge tube 4 and capillary channel 7 are installed by means of this instrument, at first outer plug is pushed into by in the connecting pipe section 2 that is pressed into fluid part expansion.Wherein plug 11 is so located, and makes its flat side 17 be close on the bigger flat board of evaporimeter intensity 8, and this flat board should not be out of shape.When expansion, be applied to this two flat boards 8 by plug 11, the fully elongation of power on 9 by side 15 so be distributed in 8 of bigger flat boards of intensity towards the side on, so that be positioned at flat board 9 opposite, that intensity is more weak on the effect pressure compare, in fact a very little pressure acts on dull and stereotyped 8, and dull and stereotyped 9 only contact in the outside, edge of plug 12 tangently.In expansion process, kept dull and stereotyped 8 planarization like this, and do not needed that first mold pressing goes out a pit as used up to now method.
In case it has formed the edge of connecting pipe section 2 of the terminal point of the side 17 of outer plug 11-at a touch shoulder 18-, outer plug 11 has just reached the necessary degree of depth that enters.Plug 12 passes the passage 13 of outer plug 11 in making now, and plug 12 directly guides in this way and enters in the capillary channel passage 6 in this.During the expansion of capillary channel passage 6, outer plug 11 remains in its position in discharging joint 2.Plug 12 side direction in connecting pipe section 2 fractures in getting rid of in this way under the effect of the propulsive force that is acted on vertically, and the flat board 8 or 9 of getting rid of possible in addition bending and evaporimeter 1 is penetrated or the damage of alternate manner.
After expansion, supply line 7 and discharge tube 8 are inserted in capillary channel passage 6 or the connecting pipe section 2 and are fixing inside.The described fixing of supply line rolls die and a die is undertaken by punching press by means of one, and wherein the fixing of discharge tube for example can be undertaken by welding.
Fig. 5 has shown that when being separated from each other motion after mold pressing processing this is to rolling die 20 and die 21 and the perspective cross-sectional view in a cross section by evaporator plate 1 on the height of the capillary channel passage 6 of mold pressing processing.Roll die 20 and/or die 21 and be equipped with (not illustrating among a figure) heater, this heater is used to weld an aluminium lamination between flat board 8,9 and capillary channel 7, and makes this capillary channel 7 and dull and stereotyped 8,9 realize being connected of sealing.Replace heater that a sonotrode that is used for ultrasonic bonding also can be set.Roll die 20 and have a groove 22 that extends along its length that is essentially semi-cylindrical form, be parallel to this groove and on die 21 surfaces, extend two gussets 23.The shape of groove 22 and gusset 23 is to determine like this, makes after mold pressing processing, and dull and stereotyped 8,9 surround supply line 7 on its whole circumference hermetically.Wherein the gusset 23 of these two cusped edges just is expressed to two parallel ripples 25 in the bigger flat board of intensity 8 at the early stage of mold pressing processing, and these two ripples are used for fixing the position of supply line 7, and stops the undesired deformation in cross section when mold pressing.
Characteristic and stability that pit 24 that therefore forms on dull and stereotyped 8 outer surface does not hinder evaporimeter 1, because its area is especially little, so that can not hinder the heat exchange between the storage in evaporimeter and the refrigeration plant, storage and evaporimeter are bonding in the described refrigeration plant, and because described pit does not extend to the edge of evaporator plate, so the moisture that does not also have evaporimeter 1 is come off enters into pit.
Fig. 6 shows the perspective view of an expander tool, and this instrument is a scheme that is changed slightly by instrument shown in Figure 4.This about plug 11 has a columniform part 28 between the shoulder 27 of a top 16 that its taper is shunk and a taper, the diameter of this part is littler than the overall diameter of discharge tube 4 to be installed in connecting pipe section 2.The diameter of part 28 even can be so little, so that this part is being insertable by being pressed in the connecting pipe section that fluid expands only, and the distortion that this connecting pipe section is added.The shape on the top 16 of taper is corresponding to the shape of the duct section 3 of taper.When this instrument that changes to some extent inserted, connecting pipe section 2 was not expanded on whole length, but as shown in Figure 7, the shoulder 29 of one of formation and shoulder 27 complementations in connecting pipe section 2.This shoulder is as the backstop of discharge tube 4.Therefore this discharge tube 4 does not need to measure entering the degree of depth and just can being advanced to by shoulder 29 formed backstops always of it in connecting pipe section 2, and does not have such danger: discharge tube 4 will take on 29 and the section 3 of taper between the refrigerant tubing 5 that enter in the connecting pipe section 2 block.
