The heat exchange fluid can flow along the apex of the zigzag branches (38) of the blades (flow direction indicated by arrow 9). According to the invention, a water flow gutter (50) extending downwards on both sides of the flat tubes (2) is designed next to the rear end region (52) of the zigzag blades (8), seen in the flow direction (arrow 9) of the outer heat exchange fluid.
Description
The present invention relates to have the flat tube evaporator that is used for automotive air conditioning device of the preamble feature of claim 1, it is particularly made with aluminum or aluminum alloy.This class flat tube evaporator is for example open from US-A-4350025.
When operation one is used for the flat tube evaporator of automotive air conditioning device, all make joint efforts automotive air conditioning device can be troublesomely in addition produce nocuously or even assemble moisture other be positioned at the zone at rear portion, prevent to blow over condensed water or other moisture under the washing away of heat-exchange fluid (normally air) externally.
Make separately in the known multithread channel flat-tube formula evaporimeter of good flat tube to single channel arrangement therein, stay vertical gap in these flat tubes that manufacturing is good separately, it can be simultaneously with the drain tank that acts on the moisture that is produced in needs.The water of this discharge can be collected and carrying-off (EP-A2-0709643) by a catch tray in needs.
But, when flat tube was not provided with separatedly, the problem of water carrying-off will appear.But, this class flat tube not separatedly application table reveal its manufacturing expense and be lower than and will be respectively make the expense of good flat tube assembling.According to US-A-4350025, when only adopting whole flat tube layout, just guaranteed the carrying-off of moisture especially, this moisture can be inner by thin plate generation in a zigzag at fin.That is to say that this invention shows, the moisture that is produced is can at first carry by outside heat exchange media in the zigzag thin plate fin and only be collected by fin at the terminal point of the distance that flows through as condensed water particularly.Therefore, in flat tube evaporator according to US-A-4350025, externally on the flow direction of heat-exchange fluid with the junction of the end region that is positioned at the back of zigzag thin plate, on a projecting part of making integratedly with flat tube, narrow end face side at flat tube, usually make from the top down a continuous gutter, this annex is made the T cross section, its middle pectoral plate is connected with the narrow end face side of flat tube, simultaneously it externally the flow direction of heat-exchange fluid cross that thin plate is outstanding in a zigzag.
In this known flat tube evaporator, the end region of T shape projecting part in the back that is positioned at the external heat exchange fluid flow direction of flat tube will strengthen the constructional depth of Master Cost and flat tube evaporator, and requires that expensive manufacturing process is arranged.In addition, the parts of freely giving prominence to from the zigzag thin plate can not receive and this moisture of carrying-off, this moisture one-tenth drips shape and keeps hanging in the inside in zigzag thin plate district, thereby can not be arranged on the rhone of zigzag thin plate back along its flow direction from the heat-exchange fluid arrival of outside.
Therefore, the present invention is based on such purpose, and the better simply manufacturing process of expense that can not need the material that adds and constructional depth obtains effective drain function with thin plate in a zigzag.
This purpose can solve in a flat tubular evaparator by claim 1.
Known, in a flat tube evaporator, its plate with flat tube the same all be capwise and between these plates, insert thin plate in a zigzag, usually form vertical gutter in the outside of plate.But, the plate of flat tube evaporator has its thicker channel walls, come compared with following flat tube, it is no problem forming a gutter therein, in the flat tube below described, directly in the scope that the single raceway groove of flat tube passes through therein, the configuration of this class ditch is normally got in touch by the cross section of inside groove and raceway groove and is formed, and condensed water discharges ditch by this inside groove formation.Therefore, the idea that this layout proposition of vertical condensed water discharging ditch in the flat outside of a flat tube all reckons without so far, promptly the whole thermodynamics operation of flat tube evaporator can remain to any degree with good efficiency at this moment.Aspect this meaning, the concrete solution of claim 2 is unique.
According to the present invention, flat tube when cutting off, coiled material can be shaped as needed separately discharging ditch simultaneously by punching press and that do not need to make, on the material and constructional surcharge.Can be provided with more discharging ditch by inside groove on demand this moment, so that in the zigzag sheet pack even sometimes have under the situation of condensed water of early stage generation in the back of the smaller section of circulation, even also intercept the condensed water of generation like this at the extension area of zigzag thin plate, and in fact in generative process, just it drained.
It is interesting especially when the fin that forms by the zigzag thin plate according to another configuration of claim 2 has close leg adjacent one another are.That is to say, it shows, on the one hand when making flat tube evaporator, moulding according to claim 2 is fairly simple, on the other hand, and near the gutter, narrower spacing between the leg of thin plate causes moisture to be assembled in these narrow places automatically in a zigzag, grow up bigger set gradually, finally when growing up in entering condensed water discharging ditch, can in the discharging ditch, further be drained on noresidue ground again later on.Further stoped moisture carrying secretly by the external heat exchange fluid that flows into like this at flow direction.
For function of the present invention, also require the discharging ditch to be arranged on condensed water in the thin plate in the scope of this place formation.But this discharging ditch will interrupt at the link of flat tube, for example will carry out the soldering with tube bottom plate at this place.Claim 3 is stipulated herein, and the inside groove that can form the gutter is not set at brazing area.For this purpose, must cut off especially, so just need one for example by amputating or the following process of the complexity that mill off carries out according to the T shape web that US-A-4350025 will locate.Within the scope of the invention, can obtain same effect like this in no problem ground, promptly needn't when the coiled material sizing is cut off, in the scope of the end of flat tube, form inside groove simultaneously from the beginning.
To illustrate in greater detail the present invention according to the schematic diagram of a plurality of embodiment below, in the drawings:
Fig. 1 shows the perspective view of flat tube evaporator, and at this moment, the longitudinal extension of flat tube 2 is vertical;
Fig. 2 shows the cross-sectional view along the flow direction of external heat exchanger body in a cross section arranging by the flat tube and the bulk of thin plate in a zigzag, and is showing details at the figure of Fig. 2 than the rear end along the flow direction of external heat exchange fluid;
Fig. 3 shows the plane that is connected two zigzag thin plates between the adjacent flat tube with the ratio of amplifying, and line of vision is the flow direction along external heat exchange fluid.
Flat-tube heat exchanger shown in Figure 1 make two runners and as the evaporimeter configuration of cooling medium circulation.
But this do not get rid of yet can with shown in feature similarly transfer on the flat-tube heat exchanger with different runner numbers.
Flat tube evaporator has following common structure:
A lot of be generally 20 to 30 flat tubes 2 that vertically extend, they are arranged to, and spaced-apart and end side 4 is in alignment with each other with constant distance.Between the planar side 6 of flat tube, sandwich thin plate 8 in a zigzag separately sandwich style.Also respectively be provided with thin plate 8 in a zigzag equally at two outer surface 4 places of the flat tube that is positioned at the outside.Each flat tube has a plurality of interior strengthening webs 10, and they are separated out the chamber 12 of working as continuous raceway groove in flat tube.According to the constructional depth difference, the number of chamber 12 is generally 10 to 30.
The typical range of the number of given flat tube 2 and its chamber 12 can only regard as preferably herein, rather than restrictive.
In an automotive air conditioning device,, arrange and to flow through with the heat exchange media of outside air in the constructional depth direction along Fig. 1 and arrow 9 shown in Figure 3 as the outside with the block that flat tube 2 and zigzag thin plate 8 are made at finished product state.
In evaporimeter, for example particularly fluorohydrocarbon (Fluorkohlenwasserstoff) is as inner heat exchange media with cooling medium, and it enters heat exchanger by input pipe 14, and comes out from heat exchanger again by output duct 16.Input pipe comes out from its condenser in the cooling medium circulation.Output duct 16 passes to the compressor of cooling medium circulation.
Cooling medium to the distribution of the input side of each flat tube is undertaken by so-called distributor.At outlet side the cooling medium of collecting is delivered to output duct 16.Though can task the chest that separates with distributing, all these two functions are combined in the common gatherer 18 with collecting branch.
This gatherer is arranged on the end side 4 of flat tube 2 for 18 this moments, and only produces a flow inversion on the other end of flat tube 2 side 4 between runner usually, carries out in the gatherer 22 oppositely common turning to according to Fig. 1 herein.
Under the limiting case of single channel heat exchanger, oppositely gatherer 22 can replace with a unshowned output gatherer.
The design of multithread road means to have one time flow divert at least in each flat tube 2 in the scope of the independent raceway groove that is formed by chamber 12.In two flow passage structures that two runner is separated from each other in each flat tube 2 by a strengthening web 10a in Fig. 1, turn to gatherer 22 not need other medial compartment demarcation strip, but need only the function that turns to that must guarantee once.Under situation about turning to, in turning to gatherer 22, need at least one central dividing plate, so that under the situation that four runners are arranged, carry out dual simply turning to more than two runners.Also want under the situation how at the runner number, must improve the number of central dividing plate where necessary.
Gatherer 18 is combined by a tube bottom plate 26 and a lid 28 under the situation of restriction of generality not, at this moment, where necessary other parts can also be set on the structure of gatherer 18.
The free end that the leaving of flat tube 2 turns to gatherer 22 and the inner space of gatherer 18 closely are bonded on the tube bottom plate 26 communicatively, and this tube bottom plate correspondingly is provided with engaging groove and is provided with interior and/or outer jointing in case of necessity.
Because input function and output function with cooling medium in gatherer 18 combine, gatherer 18 needs the configuration of at least one two Room, and it separates input side and outlet side.For this purpose, the chamber demarcation strip is at least a flat web for vertical web 32 on configuration, and it separates input area that is communicated with input pipe in the gatherer 18 and the output chamber 34 of running through gatherer 18, and this output chamber is communicated with output duct 16.
Under the situation of evaporimeter, also further need as far as possible equably the cooling medium of input side to be delivered to all flat tubes 2.Under extreme case, can deliver to each single flat tube 2 respectively by the cooling medium that a so-called distributor will be carried.But majority all is to deliver to adjacent flat tube group 2, and at this place, at least one group has one greater than one flat tube number, and at this, the number of the flat tube 2 of each group can also change.Each flat tube group 2 all is equipped with the input chamber of oneself, and the direct and relevant flat tube group 2 in this input chamber is communicated with.Cross web by flat web form when separate in the chamber this self input chamber separates each other.
In dual flow evaporator, cross web usually only extends out from a side of vertical web 32 with meeting at right angles.
In one or four runner evaporimeters, except the vertical web 32 adjacent, also be provided with parallel therewith other vertical web with output chamber 34.The latter begins to intersect to being connected with vertical web 32 from the cross web that the input chamber separately of flat tube group is separated with meeting at right angles.On the extensions of cross web, between two vertical webs, usually be separated out one with separately oneself the adjacent reversal chamber in input chamber that is positioned at the outside, to be used for second runner being diverted to the 3rd runner at gatherer 18.
When the runner number of 18 guiding of the gatherer by having the function of turning to for a long time, to correspondingly strengthen vertical web number and in turn to the number of chambers, they usually along gatherer laterally in the inside and be clipped between the input chamber of flat tube group 2 separately and between the output chamber.
In the finished product heat exchanger, by flat tube 2 and in a zigzag the block formed of thin plate 8 in the side with usually being side plate 36 sealings adjacent, so that side plate 36 formation one are used for the outside framework of the extraneous air of inflow heat exchanger block with outer zigzag thin plate.
The tube bottom plate 26 of flat tube 2, zigzag thin plate 8, gatherer and lid 28 and the chamber separator that is provided with where necessary and the side plate 36 of heat exchanger, preferably as input pipe 14 and output duct 16, all use aluminium and/or aluminium alloy manufacturing, and comprise the portion section adjacent of pipe joint, all become the finished product evaporimeter with solder brazing with heat exchanger.
Though be not illustrated, in practice, for the cooling medium evaporimeter that is used for according to the air conditioning equipment of car of Fig. 1, input pipe 14 that can flow through by the corresponding connecting branch in gatherer 18 and output duct 16 are connected on two corresponding connecting branches of a shutoff valve of can hot static(al) ground regulating.This shutoff valve has two the other input pipe sides and the connecting branch of outlet side at invisible opposite side.
Tube bottom plate 26 and lid 28 are formed by the plate with the cored solder coating.The edge of lid engages with tube bottom plate 26 at this moment and has at least one to stress to fold.
Can know when investigating Fig. 3 that at first relevant cutaway view is that a raceway groove 12 by the flat tube 2 of two capwises parallel to each other cuts out.But it is situation by the strengthening web 10 of same flat tube 2 that following explanation also is suitable for working as the section of being investigated.
Show the flow direction 9 rectangular special layouts of zigzag thin plate 4 and external heat exchange fluid, and be that streamwise is looked.The single leg of thin plate vertically is connected to each other by circular arc summit 40 along the flow direction extension of the arrow 9 of external heat exchange fluid and in the continuity direction while of zigzag thin plate for 38 this moments in a zigzag.This summit 40 usually is fixed on the adjacent plane side of adjacent flat tube 2 by the position 42 of solder brazing.The layout of leg 38 and summit 40 and configuration will so be carried out at this moment, so that in the rate of curving of summit 40 part, be used for flowing freely cross section greater than the cross section that flows freely in the scope of the free distance 44 of two summits adjacent with this flat tube 2 according to the external heat exchange fluid of arrow 9.What thus, the medial compartment 46 between the adjacent legs 38 of zigzag thin plate 8 was done than in the adjacent body of summit 40 in the scope of free distance 44 is narrow.So just cause in the scope at the narrow place that delimit separately by free distance 44, under capillary influence, can accomplish that the capillary type of the moisture carried secretly by external heat exchange fluid deposits 48.
This liquid deposition 48 is collected in according to collecting on the rear end of the width extension of zigzag thin plate 8 on the flow direction of the external heat exchange fluid of arrow 9 or by its leg 38.Should consider within the scope of the invention, when arranging and designing the zigzag thin plate according to Fig. 3, or when relating to the similar arrangements that produces liquid deposition 48 and designing, guarantee to deposit 48 and can not rest in a zigzag in the thin plate 8 and make cross section stenosis in it, but at least often on purpose by carrying-off.
To this, advantageously, near liquid deposition 48, promptly along the flow direction of external heat exchange fluid one device with the liquid carrying-off collected is being set in the zone of back according to arrow 9.
To this, in the embodiment shown in all three, all according to arrow 9 along the flow direction of external heat exchange fluid near the rearward-facing end of zigzag thin plate or from its leg 38 beginnings vertical continuous gutter 50 from the top down of each self-forming on each of two adjacent flat tubes 2.
At this moment, all set out thus in all embodiments, promptly along the direction of arrow 9, thin plate 8 all surpasses adjacent flat tube 2 nose section length 52 usually in a zigzag, and this normally is used to realize characteristics of the present invention.
Corresponding to the embodiment as Fig. 2, vertical gutter 50 separately forms at the vertical inside groove on the planar side of adjacent zigzag thin plate 60 by adjacent flat tube 2, and at this moment, inside groove is preferably on the wall of a raceway groove 12 and makes.Though relevant inside groove 60 also can be made on the rearmost raceway groove 12 of separately flat tube 2 along the flow direction of external heat exchange fluid according to arrow 9, but it also is same good as shown in Figure 2, formation being gone up at the raceway groove (streamwise is looked at the penult raceway groove) of a front herein in the gutter.At this moment, suitable is that these inside grooves are provided with respect to the free distance 44 between the adjacent legs 38 of zigzag thin plate 38 separately.
In addition, as can be seen from Figure 1, do not form separately inside groove 60 at the link 62 of flat tube 2.
