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 9 of the paddy portion (bottom) of the ripple of upside heat transfer plate 2 and the end 10 of the mountain portion of lower side panel, formation is in abutment 11 (contact site) short size, upper and lower plates (upside heat transfer plate 2 and downside heat transfer plate 3) from the 2-3 of outer peripheral edges portion at short-axis direction (Z direction).Like this, can shorten size a among the figure (from the size of outer peripheral edges portion 12) and be characteristic towards short-axis direction (Z direction).Size a is from the size of the 2-3 of outer peripheral edges portion towards short-axis direction (Z direction).
And, be in the abutment of short size at short-axis direction (Z direction) and refer to the abutment that occurs at first from the occasion that the 2-3 of outer peripheral edges portion has advanced at short-axis direction.
More specifically describe below.In Fig. 2, the solid line on the surface of upside heat transfer plate 2 is represented waveform, and dotted line representes to be in the waveform of downside heat transfer plate 3 of the downside of upside heat transfer plate 2.The scope 32 that has surrounded with interrupted wire frame is represented the cross sectional shape of the ripple of upside heat transfer plate 2.Dotted line x1, y1, z1 represent mountain, paddy, mountain successively.The scope 33 that has surrounded with interrupted wire frame is represented the cross sectional shape of the ripple of downside heat transfer plate 3.Dotted line x2, y2, z2 represent paddy, mountain, paddy successively.In Fig. 2 (stacked direction to looking); The wave crest portion of imaginary many bottom crest lines 21 that extend as the wave base portion upside heat transfer plate 2 of the plate that adjoins each other and downside heat transfer plate 3, expression upside heat transfer plate 2 and in the direction different with the direction of long limit 2-2 etc. and expression downside heat transfer plate 3 and imaginary many top crest lines 22 that extend in the direction different with the direction of long limit 3-2 etc. intersect, and form intersection point 23.So, engage (contact) and form abutment (contact site) at intersection point 23 by each bottom crest line the wave base portion that representes and the wave crest portion that representes by each top crest line.In this constitutes; Upside heat transfer plate 2 and downside heat transfer plate 3 be present in a certain root bottom part crest line for example in the intersection point on the crest line 21 of bottom, near intersection point 23 corresponding engagement points 11 along the end of the 2-3 of outer peripheral edges portion of long limit 2-2, be formed on along the 2-3 of outer peripheral edges portion of length limit 2-2 consistent location roughly.
Fig. 3 representes the occasion that the size b corresponding with size a is longer than size a with respect to Fig. 2.Promptly; Occasion at Fig. 3; Be present in the intersection point of bottom on the crest line 21, near intersection point 23 corresponding engagement points 11, from leaving the formation of size b ground in (Z direction) position of having left to the inside along the 2-3 of outer peripheral edges portion of long limit 2-2 along the end of the 2-3 of outer peripheral edges portion of long limit 2-2.In this size b short occasion as the size a of Fig. 2, the stream broadening, for this reason, the flow velocity when flowing through same flow descends, and the pressure loss reduces.In addition, in the short occasion of size a, can reduce the hold-up of solder, for this reason, effectively heat transfer area increases, and heat exchange performance improves.Through shortening size a in this wise, can suppress pressure loss increase, and can improve heat exchange performance.Therefore; Can make the necessary plate number with respect to the heat-exchangers of the plate type of the necessary ability of air conditioner is Min.; And; Can the delay of foreign matters such as the refrigerator oil in the heat-exchangers of the plate type, grit be suppressed, so, can provide and suppress cost and the high heat-exchangers of the plate type of reliability.If heat-exchangers of the plate type 100 then also can use hydrocarbon, the low so big fluid of the pressure loss of GWP cold-producing medium.
Heat-exchangers of the plate type 100 by embodiment 1 can obtain following effect.
(1) crushing: heat-exchangers of the plate type 100 can make the pressure loss of fluid reduce effectively.Form the configuration of the roughly consistent ripple of the abutment that is in the upper and lower plates of short size at short-axis direction with respect to the outer peripheral edges portion of the long axis direction of plate and the outer peripheral edges portion of long axis direction.Like this, with respect to outer peripheral edges portion short-axis direction be in the distance at the abutment of the upper and lower plates of short size (size a) shortens, so, can reduce the hold-up of the solder that circumference outside forms, enlarge stream, for this reason, can reduce the pressure loss.
(2) efficient: in addition,,, the board-like heat exchanger with good heat exchanger effectiveness can be provided so the heat transfer effective area also increases because stream enlarges.
(3) miniaturization: the heat-exchangers of the plate type that improve heat transfer between plate in this wise, has reduced the pressure loss can reduce the sheet number of range upon range of plate, can cut down manufacturing costs such as fee of material, processing charges significantly.
(4) CO

In above embodiment 1; Heat-exchangers of the plate type is by the multi-disc plate stack of the via hole that is provided with the gateway that becomes fluid at four jiaos and constitute; In this heat-exchangers of the plate type, explain that disposing the rolling land by abutment that is in the upper and lower plates of short size with respect to the outer peripheral edges portion of the long axis direction of plate at short-axis direction and the outer peripheral edges portion of long axis direction roughly consistent mode has carried out the heat-exchangers of the plate type that engages.
In above embodiment 1; The end points 9 (terminal of bottom crest line) of the trough portion through making upside heat transfer plate 2 is consistent with the end points 10 (terminal of top crest line) of the mountain portion of downside heat transfer plate 3, makes the 2-3 of outer peripheral edges portion of plate and the distance that is in the abutment 11 of the upper and lower plates of short size at short-axis direction (Z direction) for minimum.That is, make this abutment 11 roughly consistent with the 2-3 of outer peripheral edges portion.Like this, make the pressure loss reduce.Below, in embodiment 2, the abutment of the upper and lower plates of short size has the occasion of particular distance (the specific dimensions b that afterwards states) be at short-axis direction (Z direction) in the outer peripheral edges portion of the long axis direction of display plate (along the outer peripheral edges portion on long limit).
Describe with reference to the Fig. 3 that in embodiment 1, has used once more.In embodiment 1, explained that the occasion of degree that size b is short to size a is to the effective this point of the minimizing of the pressure loss.In this embodiment 2, do not have little degree to size a even size b is described, if be in the scope of regulation, then stream obtain guaranteeing, suitable occasion.
If the outer peripheral edges portion of plate is too small with the size b that is in the abutment 11 of the upper and lower plates of short size at short-axis direction (Z direction); Promptly; Size b is not small enough to size a degree, and is small enough to the such halfway degree of effect that can not obtain size a, the problem below then existing.The solder with abutment solder circumference outside compiles during soldering, and solder is detained between size b, and stream narrows down.On the other hand; If size b is wide; Then the abutment 11 of upper and lower plates shortens with the size at the abutment 13 (on top crest line 22, being only second to abutment 11 second near outer peripheral edges portion) on the next door at abutment 11, and the solder at abutment 11 and abutment 13 gathers; Solder is detained between these abutments, and stream narrows down.In the plate of embodiment 2, size b is set at the size of the regulation that solder is not detained.Like this, also work as the stream of fluid in the zone of size b.If have the heat-exchangers of the plate type of such structure, then pressure loss minimizing and heat transfer area enlarge and become possibility.
For example, when the short-axis direction of plate was of a size of 70mm, size b was preferably 3～4.5mm.Size b can adjust corresponding to size, wave angle degree θ, wave pitch, the rerum natura of fluid, the service condition of the short-axis direction of plate.For example in Fig. 3, when size b was 3～4.5mm, that preferably wave angle degree θ (the wave angle degree θ 1 of upside heat transfer plate 2, the wave angle degree θ 2 of downside heat transfer plate 3) is 60 degree was above～below 70 degree about.If the scope of 62.5 degree～67.5 degree is then better.
As above; Upside heat transfer plate 2 and downside heat transfer plate 3 each other with the intersection point that is present on the root bottom part crest line in, near intersection point corresponding engagement point (contact site) along the end of the outer peripheral edges portion on long limit; Corresponding to the direction of the extension of direction of the extension of bottom crest line (by the direction of the bottom crest line of wave angle degree θ 1 decision) and top crest line (by the direction of the top crest line of wave angle degree θ 2 decisions), be formed on from outer peripheral edges portion and left distance (3～4.5mm) the position of stipulating at short side direction (Z direction) along long limit.
And, the direction of approaching with the direction of the top crest line direction quadrature with long limit of upside heat transfer plate 2 with the direction of the bottom crest line of downside heat transfer plate 3, then the junction surface is formed on the outer peripheral edges portion of growing the limit from the edge and leaves position far away more.That is, preferably wave angle degree θ 1 and wave angle degree θ 2 are more near 90 degree, and then size b increases about " 3～4.5mm " more.
In above embodiment 2; Heat-exchangers of the plate type is by the multi-disc plate stack of the via hole that is provided with the gateway that becomes fluid at four jiaos and constitute; In this heat-exchangers of the plate type, explained plate long axis direction outer peripheral edges portion be in the abutment of the upper and lower plates of short size at short-axis direction and left the heat-exchangers of the plate type of the size b of regulation.
With reference to Fig. 4 embodiment 3 is described below.In above embodiment 1,2, be the abutment that relates to upper and lower plates and the occasion of the size (distance) between the outer peripheral edges portion.Below, in embodiment 3, the occasion of crest line of ripple of a side's who has shortened upper and lower plates plate is described.
