And, in fig. 8, illustrate section AA ' (Fig. 1 (c)), cross section BB ' ~ cross section DD ' (Fig. 2).
(form and illustrate)
As shown in Figure 1, in heat-exchangers of the plate type 100, multiple there is minor face (the minor face 2-1 of upper-side heat transfer plate 2, the minor face 3-1 of lower-side heat transfer plate 3), long limit (the long limit 2-2 of upper-side heat transfer plate 2, the long limit 3-2 of lower-side heat transfer plate 3) and formed to the rectangular slab of the edge, periphery (edge, the periphery 2-3 of upper-side heat transfer plate 2, edge, the periphery 3-3 of lower-side heat transfer plate 3) in the space that fluid seals by long limit each other, minor face each other, the mode that overlaps each other of edge, periphery is stacked.Each plate is embodied in the processing of the waveform that stacked direction (X-direction) conjugates.
Fig. 2 is the front view of heat transfer plate.Fig. 2 is the enlarged drawing of the scope Y of Fig. 1 (f).In fig. 2, the end 10 in the end 9 of the valley (bottom) of the ripple of upper-side heat transfer plate 2 and the mountain portion of lower side panel, formed from the 2-3 of edge, periphery short-axis direction (Z-direction) be in the shortest size, the abutment 11(contact site of upper and lower plates (upper-side heat transfer plate 2 and lower-side heat transfer plate 3)).Like this, size a(can be shortened in figure from edge, periphery 12 towards the size of short-axis direction (Z-direction)) be feature.Size a is the size from edge, periphery 2-3 towards short-axis direction (Z-direction).
And, the abutment occurred at first in the occasion that short-axis direction has advanced from edge, periphery 2-3 is referred at the abutment that short-axis direction (Z-direction) is in the shortest size.
More specifically be described below.In fig. 2, the solid line on the surface of upper-side heat transfer plate 2 represents waveform, and dotted line represents the waveform of the lower-side heat transfer plate 3 of the downside being in upper-side heat transfer plate 2.The scope 32 surrounded with interrupted wire frame represents the cross sectional shape of the ripple of upper-side heat transfer plate 2.Dotted line x1, y1, z1 represent mountain, paddy, mountain successively.The scope 33 surrounded with interrupted wire frame represents the cross sectional shape of the ripple of lower-side heat transfer plate 3.Dotted line x2, y2, z2 represent paddy, mountain, paddy successively.In Fig. 2 (stacked direction to looking), as the plate adjoined each other upper-side heat transfer plate 2 and lower-side heat transfer plate 3, the wave base portion that represents upper-side heat transfer plate 2 and imaginary many bottom crest lines 21 extended in the direction different from the direction of long limit 2-2 etc. with represent the wave crest portion of lower-side heat transfer plate 3 and imaginary many top crest lines 22 etc. extended in the direction different with the direction of long limit 3-2 intersect, formation intersection point 23.So the wave base portion represented by each bottom crest line engages (contact) with the wave crest portion represented by each top crest line at intersection point 23 and forms abutment (contact site).In this is formed, upper-side heat transfer plate 2 and lower-side heat transfer plate 3 with in the intersection point be present on a certain root bottom part crest line such as bottom crest line 21, closest to along abutment 11 corresponding to the intersection point 23 of the end of edge, the periphery 2-3 of long limit 2-2, be formed in the position roughly consistent with edge, the periphery 2-3 along long limit 2-2.
Fig. 3, relative to Fig. 2, represents the occasion that the size b corresponding with size a is longer than size a.Namely, in the occasion of Fig. 3, with in the intersection point be present on the crest line 21 of bottom, the closest abutment 11 corresponding along the intersection point 23 of the end of edge, the periphery 2-3 of long limit 2-2, formed with leaving size b from edge, the periphery 2-3 position that (Z-direction) have left to the inside along long limit 2-2.In the occasion that this size b is short as the size a of Fig. 2, stream broadening, for this reason, flow velocity when flowing through same flow declines, and the pressure loss reduces.In addition, in the occasion that size a is short, can reduce the hold-up of solder, for this reason, effective heat transfer area increases, and heat exchange performance improves.By shortening size a in this wise, can suppress pressure loss increase, and can heat exchange performance be improved.Therefore, the necessary plate number that can make the heat-exchangers of the plate type of the necessary ability relative to air conditioner is Min., and, can suppress the delay of the foreign matters such as the refrigerator oil in heat-exchangers of the plate type, grit, so, can provide and inhibit cost and the high heat-exchangers of the plate type of reliability.If heat-exchangers of the plate type 100, then the fluid that the pressure loss that hydrocarbon, low GWP cold-producing medium also can be used such is large.
Following effect can be obtained by the heat-exchangers of the plate type 100 of embodiment 1.
(1) crushing: heat-exchangers of the plate type 100 can make the pressure loss of fluid reduce effectively.The edge, periphery be formed as relative to the long axis direction of plate is in the configuration of the abutment of the upper and lower plates of the shortest size ripple roughly consistent with the edge, periphery of long axis direction at short-axis direction.Like this, be at short-axis direction relative to edge, periphery the abutment of the upper and lower plates of the shortest size distance (size a) shortens, so, the hold-up of the solder that circumference is outside formed can be reduced, expand stream, for this reason, can the pressure loss be reduced.
(2) efficiency: in addition, because stream expands, so heat transfer effective area also increases, and can provide the board-like heat exchanger with excellent heat exchanger effectiveness.
(3) miniaturized: to improve the heat transfer between plate in this wise, decrease the sheet number that the heat-exchangers of the plate type of the pressure loss can reduce stacked plate, the manufacturing cost such as fee of material, processing charges can be cut down significantly.
(4) CO
2discharge and reduce: according to the air-conditioning equipment being loaded with this heat-exchangers of the plate type, cheap, and also power consumption amount is inhibited, CO
2discharge rate also can reduce.In addition, the minimizing of the pressure loss can suppress the refrigerator oil, sludge, grit blocking etc. be detained in a heat exchanger, and its reliability also improves.
In above embodiment 1, heat-exchangers of the plate type is folded by the multi-disc flaggy of the via hole being provided with the gateway becoming fluid in corner and forms, in this heat-exchangers of the plate type, the edge, periphery illustrating by the long axis direction relative to plate is in the abutment of the upper and lower plates of the shortest size mode roughly consistent with the edge, periphery of long axis direction and configures the heat-exchangers of the plate type that rolling land engages at short-axis direction.
Embodiment 2.
In above embodiment 1, by making the terminal of crest line bottom the end 9(in the trough portion of upper-side heat transfer plate 2) with the terminal of 10(top, the end crest line in the mountain portion of lower-side heat transfer plate 3) consistent, make edge, the periphery 2-3 of plate be minimum with the distance being in the abutment 11 of the upper and lower plates of the shortest size at short-axis direction (Z-direction).That is, make this abutment 11 roughly consistent with edge, periphery 2-3.Like this, the pressure loss is reduced.Below, in embodiment 2, edge, periphery (edge, periphery along long limit) and the abutment being in the upper and lower plates of the shortest size at short-axis direction (Z-direction) of the long axis direction of display plate have the occasion of specific distance (specific dimensions b described later).
Be described referring again to the Fig. 3 employed in embodiment 1.In embodiment 1, describe the effective this point of the minimizing of occasion to the pressure loss that size b is short to the degree of size a.In present embodiment 2, even if illustrate that size b does not have the little degree to size a, if place within the limits prescribed, then stream obtain guaranteeing, suitable occasion.
If the edge, periphery of plate is too small with the size b being in the abutment 11 of the upper and lower plates of the shortest size at short-axis direction (Z-direction), namely, size b is not small enough to size a degree, and is small enough to the such halfway degree of the effect that can not obtain size a, then there is following problem.The collecting with the solder at the abutment of solder of circumference outside during soldering, solder is detained between size b, and stream narrows.On the other hand, if size b is wide, then the abutment 11 of upper and lower plates and the abutment 13(on the side at abutment 11 are on top crest line 22, be only second to abutment 11 second close to edge, periphery) size shorten, abutment 11 is gathered with the solder at abutment 13, solder is detained between these abutments, and stream narrows.In the plate of embodiment 2, size b is set as the size of the regulation that solder is not detained.Like this, also work as the stream of fluid in the region of size b.If have the heat-exchangers of the plate type of such structure, then pressure loss minimizing and heat transfer area expand and become possibility.
Such as, when the short-axis direction of plate is of a size of 70mm, size b is preferably 3 ~ 4.5mm.Size b can adjust corresponding to the size of the short-axis direction of plate, wave angle degree θ, wave pitch, the physical property of fluid, service condition.Such as in figure 3, when size b is 3 ~ 4.5mm, best wave angle degree θ (the wave angle degree θ 1 of upper-side heat transfer plate 2, the wave angle degree θ 2 of lower-side heat transfer plate 3) is about more than 60 degree ~ less than 70 degree.If the scope of 62.5 degree ~ 67.5 degree is then better.
As described above, upper-side heat transfer plate 2 and lower-side heat transfer plate 3 each other with in the intersection point be present on a root bottom part crest line, closest to along abutment (contact site) corresponding to the intersection point of the end of the edge, periphery on long limit, corresponding to the direction (direction of the top crest line determined by wave angle degree θ 2) of the direction (direction of the bottom crest line determined by wave angle degree θ 1) of the extension of bottom crest line and the extension of top crest line, be formed in the position of the distance (3 ~ 4.5mm) that have left regulation from the edge, periphery along long limit at short side direction (Z-direction).
And the direction that upper-side heat transfer plate 2 is orthogonal with direction that is more close with the direction of top crest line and long limit, the direction of the bottom crest line of lower-side heat transfer plate 3, then junction surface is formed in and leaves position far away from the edge, periphery along long limit.That is, best wave angle degree θ 1 and wave angle degree θ 2 is more close to 90 degree, then size b more increases from " 3 ~ 4.5mm " left and right.
In above embodiment 2, heat-exchangers of the plate type is folded by the multi-disc flaggy of the via hole being provided with the gateway becoming fluid in corner and forms, in this heat-exchangers of the plate type, the edge, periphery describing the long axis direction of plate have left the heat-exchangers of the plate type of the size b of regulation with the abutment being in the upper and lower plates of the shortest size at short-axis direction.
Embodiment 3.
Referring to Fig. 4, embodiment 3 is described.In above embodiment 1,2, for relating to the occasion of the size (distance) between the abutment of upper and lower plates and edge, periphery.Below, in embodiment 3, the occasion of the crest line of the ripple of the plate of the side shortening upper and lower plates is described.
Fig. 4 is the front view of the plate of embodiment 3.Upper-side heat transfer plate 2 and lower-side heat transfer plate 3 is showed in the same manner as Fig. 2.Such as shown in Fig. 4, shorten the crest line of ripple of upper-side heat transfer plate 2, make the terminal of crest line bottom the end 9(of ripple) compare the terminal of 10(top, the end crest line of lower side panel) be formed in inside plate.Like this, the stream of region c that surrounds of formation dashed line in the diagram.
By such stream c is formed in side, edge, periphery, solder collecting outward between circumference and " being in the abutment of the upper and lower plates of the shortest size at short-axis direction " can be avoided to cause flow path width to reduce.In addition, the plate of a side owing to being waveform, so, the pressure loss can be reduced when maintain the heat transfer facilitation effect produced by the stirring action that flows and being constant.In addition, at fluid of more than two kinds along the dynamic occasion of plate current, also can lose the mode compoboard that large fluid side is the short plate of the crest line of ripple, the pressure loss is little fluid side is the long plate of the crest line of ripple by pressing force, form heat exchanger.Fig. 4 at two outer circumferential side forming region c of the short-axis direction of plate, but also can make the distribution of the differential pressure in plate become equably only at the outer circumferential side setting area c of a side corresponding to the direction, gateway of fluid.
In above embodiment 3, heat-exchangers of the plate type is folded by the multi-disc flaggy of the via hole being provided with the gateway becoming fluid in corner and forms, in this heat-exchangers of the plate type, describe the heat-exchangers of the plate type of the crest line of the ripple of the plate of the side shortening upper and lower plates.
Embodiment 4.
Referring to Fig. 5, embodiment 4 is described.In aforementioned embodiments 3, describe the occasion of the crest line of the ripple of the plate of the side shortening upper and lower plates.In present embodiment 4, the occasion of crest line of the ripple shortening upper and lower plates two side is described.
Fig. 5 is the front view of the heat transfer plate of embodiment 4.If shorten the crest line of the ripple of upper and lower plates two side, then the stream of the region d surrounded with dashed line in formation figure.Side, circumference forms such stream outside, prevents the flow path width caused that collects of solder from reducing.Comprise dirt, cellulosic fluid easily becomes the starting point of stream obturation at the abutment of upper and lower plates, if but the formation of Fig. 5, then dirt, cellulosic are from the flow path of region d, thus effectively.In addition, even if to there is pressure increase due to the obturation of stream at high-pressure fluids such as cold-producing mediums, likely develop into pipe arrangement and to break such occasion in the past, refrigerator oil accumulate make in a heat exchanger to compressor oil return delay, likely made the damaged such occasion of compressor in the past, the stream of the region d of Fig. 5 becomes bypass flow path, can prevent above-mentioned occasion.
As described in above embodiment 3,4, as at least either party the plate in the upper-side heat transfer plate 2 of adjacent plate and lower-side heat transfer plate 3, there is distance W(Fig. 4, the Fig. 5 by the regulation from the direction (Z-direction) gone to another long limit along edge, the periphery 2-3 on long limit) scope and size L(Fig. 4, Fig. 5 from the direction that a minor face goes to another minor face) the region c of undressed waveform or region d.
