On plate, can also be provided with the flange plug surface of circumferential projection, when two plates are stacked mutually, the mutually tight butt of a part for the flange plug surface between plate and plate.
As shown in Figure 6, guiding device 4 is the waveform bonding jumper with several U-shaped bendings of a strip, the opening direction that comprises several bending parts, the first sprue 41 and the second sprue 42, the first sprues 41 that form by bending is contrary with the opening direction of the second sprue.
This guiding device 4 wave to width be not more than the width of plate, the height of the wave of this guiding device 4 is not more than heat transfer zone on the plate length on plate length direction, optionally, on two ends of the waveform guiding device 4 of this strip, hold back extended the first epitaxy part 43 in oriented both sides and the second epitaxy part 44.
When in the certain situation of the size of heat exchanger, the number of the U-shaped bending of guiding device 4 is more, heat transferring medium in the runner of heat exchanger flow more complicated, the coefficient of heat transfer is higher, the number of U-shaped bending is required to determine by size and the concrete heat exchange of heat exchanger, here the number of U-shaped bending is not limited.
Here the shape of guiding device 4 is not unique, can also be V-type, sinusoidal waveform etc., can also be in the U-shaped bending of this guiding device 4, to do hypotenuse processing, the aperture area from bending opening to bending part is reduced gradually.This guiding device 4 can also be other waveform shape or class waveform shape, here the shape of guiding device 4 is not limited, as long as waveform or the class waveform shape that can meet design requirement can be served as guiding device 4.
Optionally, guiding device 4 adopts the waveform bonding jumper of U-shaped bending, simple in structure, handling ease, and cost is low.
As shown in Figure 7, guiding device 4 is arranged between the first plate 2 and the heat transfer zone of the second plate 3, after plate closed assembly, the concave and convex direction of four port zone on the first plate 2 is contrary with the concave and convex direction of four port zone of the second plate 3, heat exchange is carried out in the heat exchange region that Shi Yi road heat transferring medium can enter between plate, stop another road heat transferring medium to enter this heat exchange region but enter the heat exchange region forming on adjacent heat exchanger plates face, heat exchange is carried out in the isolation having realized between two kinds of heat transferring mediums.The space between two adjacent plate is divided into two parts by guiding device, be respectively the first space and second space, transverse concave groove on the first space, second space and plate forms the mobile runner of heat transferring medium, and the space namely forming after closed assembly between the first plate 2, the second plate 3 and guiding device 4 is for the mobile runner of heat transferring medium.
The closed assembly mode of the first plate 2 and the second plate 3 can have two kinds, be respectively: 1, the setting that is staggered of the transverse concave groove on the transverse concave groove on the heat transfer zone on the first plate 2 reverse side and adjacent the second plate 3 fronts, i.e. projection on the first plate 2 reverse side and the corresponding setting of depression on the second plate 3 fronts; 2, the transverse concave groove of the heat transfer zone on reverse side and the corresponding setting of transverse concave groove on adjacent the second plate 3 fronts on the first plate 2.
As shown in Figure 8, Figure 9, in the time adopting the first closed assembly mode, in the time that plate is stamping, the transverse concave groove of the heat transfer zone in the first plate 2 fronts is arranged and is arranged identical with the transverse concave groove of the heat transfer zone in the second plate 3 fronts, if the first plate 2 adopts concavo-convex mode to arrange, the second plate 3 also adopts concavo-convex mode to arrange.
As shown in figure 10, optionally, depth of groove and the height of projection of the port zone on two plates are D, the degree of depth of the transverse concave groove of heat transfer zone is d, the depth of groove D of port zone is greater than the depth d of heat transfer zone transverse concave groove, like this, because the depth of groove D of port zone is greater than the depth d of heat transfer zone transverse concave groove, after the first plate 2 and the second plate 3 are stacked, between the first plate 2 and the second plate 3, can reserve certain space, the width in this space is the difference sum between the depth of groove D of port zone and the depth d of heat transfer zone transverse concave groove of two plates.
In the time that two plates are stacked, port zone butt on port zone on the first plate 2 and adjacent the second plate 3, because the depth of groove D of port zone is greater than the depth d of heat transfer zone transverse concave groove, certain space is left in the heat transfer zone of two plates, guiding device 4 can be arranged in the space between the projection of the first plate 2 reverse side and the projection in the second plate 3 fronts, the thickness H of guiding device 4 be difference between the depth of groove D of port zone and the depth d of heat transfer zone transverse concave groove of two plates and.
Certainly the thickness H of guiding device 4 might not be 2*(D-d), also can be less than 2*(D-d).Here the thickness H of guiding device 4 is set to 2*(D-d), make can fit together closely between plate and guiding device 4, by welding manners such as solderings, plate makes together with can be welded and fixed with guiding device 4, make heat-exchangers of the plate type compacter, also can prevent the displacement of guiding device 4 between plate.
As shown in figure 11, in the time adopting the second closed assembly mode, in the time that plate is stamping, the transverse concave groove of the heat transfer zone in the first plate 2 fronts is arranged and the setting that is staggered of arranging of the transverse concave groove of the heat transfer zone in the second plate 3 fronts, if the first plate 2 adopts concavo-convex mode to carry out groove and arranges, the second plate 3 adopts the mode of convex-concave convex-concave to carry out groove to arrange.
Optionally, depth of groove and the height of projection of the port zone on two plates are D, the degree of depth of the transverse concave groove of heat transfer zone is d, the depth of groove D of port zone is greater than the depth d of heat transfer zone transverse concave groove, like this, because the depth of groove D of port zone is greater than the depth d of heat transfer zone transverse concave groove, after the first plate 2 and the second plate 3 are stacked, between the first plate 2 and the second plate 3, can reserve certain space, the width in this space is the difference sum between the depth of groove D of port zone and the depth d of heat transfer zone transverse concave groove of two plates.
In the time that two plates are stacked, the port zone butt on the port zone on the first plate 2 and adjacent the second plate 3.Because the depth of groove D of port zone is greater than the depth d of heat transfer zone transverse concave groove, guiding device 4 can be arranged in the space between the projection of the first plate 2 reverse side and the projection in the second plate 3 fronts, and the thickness H of guiding device 4 is the difference sum between the depth of groove D of port zone and the depth d of heat transfer zone transverse concave groove of two plates.
Certainly the thickness H of guiding device 4 might not be 2*(D-d), also can be less than 2*(D-d).Here the thickness H of guiding device 4 is set to 2*(D-d), make can fit together closely between plate and guiding device 4, by welding manners such as solderings, plate makes together with can be welded and fixed with guiding device 4, make heat-exchangers of the plate type compacter, also can the displacement of mode guiding device 4 between plate.
The mode to angular flux due to what adopt in present embodiment, the first plate 2 and the second plate 3 need two templates to make, those skilled in the art is understood that, here the depth of groove of the port zone on the first plate 2 and the second plate 3 is set to identical, but be not restricted to the first plate 2 identical with the depth of groove of port zone the second plate 3, the depth of groove of the port zone on two plates can be not identical yet, same, the transverse concave groove degree of depth of the heat transfer zone on two plates can be not identical yet.But the relation of the thickness of guiding device 4 and plate upper groove and transverse concave groove is constant, the thickness of guiding device 4 is still the difference sum between the depth of groove of two plate port zone and the degree of depth of heat transfer zone transverse concave groove.The set-up mode adopting in the present embodiment, not only makes heat-exchangers of the plate type compacter, can also make the distribution of heat transferring medium in runner more even.
As shown in figure 12, the drainage trough on plate is transverse concave groove, when two plates are stacked, together with the groove of port zone is connected to mutually with projection, owing to having certain distance h between the top of the drainage trough on the relative plate face of two adjacent plate and top.Thereby, heat transferring medium flows into the space between plate from projection and the groove relative separation placement of port zone, part heat transferring medium directly flows into heat transfer zone downwards from port zone, another part heat transferring medium flows into heat transfer zone after by the space between drainage trough, the inflow heat transfer zone that can make heat transferring medium disperse, prevents the problems such as the heat exchange that the concentrated inflow heat transfer zone of heat transferring medium causes is inhomogeneous, heat exchange efficiency is low.
Here the groove setting that it should be pointed out that drainage trough is not unique, can also be other set-up mode, has the structure in the mobile space of heat transferring medium can be applied in the drainage trough structure in plate between the drainage trough between two plates as long as make.In the present embodiment, the transverse concave groove that the transverse concave groove of drainage trough is set to heat transfer zone is identical, processes simplyr, and cost is low.
Because the type of flow of heat transferring medium between each plate is similar, below by Figure 13 and Figure 14, flowing as mobile describe of example heat exchanging medium in heat-exchangers of the plate type take heat transferring medium on the second plate 3 and guiding device 4.
As shown in figure 13, heat transferring medium is from the seven apertures in the human head mouth 331 as import of seven apertures in the human head mouth region 33 flows into, and a part of heat transferring medium directly flows into heat transfer zone downwards from port zone, and another part heat transferring medium flows into heat transfer zone after by the space between drainage trough.Afterwards, owing to being provided with guiding device 4 between two adjacent plate, so just entered the heat transferring medium of heat transfer zone owing to being subject to stopping of guiding device 4, will flow downward along the first opening up sprue 41 of the waveform bonding jumper of U-shaped bending, but owing to being subject to the obstruction of U-shaped bending part of guiding device 4, heat transferring medium can not flow to along the first sprue 41 of guiding device 4 aperture at lower exit place.
As shown in Figure 13 and Figure 14, because the pressure in exit is less than the pressure of import department, the second sprue 42 is communicated with the octal mouth 341 of octal mouth region, downstream 34, so heat transferring medium can flow and inlet opening the second sprue 42 that is positioned at downstream down to the both sides of the first sprue of guiding device 4 by the second transverse concave groove 351 on the second plate 3, the heat transferring medium that flows into the second sprue 42 directly flows to the octal mouth 341 at lower exit place along the second sprue 42.Like this, in the process that heat transferring medium flows downward along the first sprue 41, constantly flow into the second sprue 42 by the transverse concave groove on plate, final, heat transferring medium all can flow out and flow to the octal mouth 341 that is positioned at lower exit from the second sprue 42.
In order to prevent that heat transferring medium is not subject to stopping of guiding device 4 directly to flow to the aperture that is positioned at lower exit place from two edges in plate edge, need guiding device 4 wave to width and the width of plate between difference keep within the specific limits, optionally, the width of plate and guiding device 4 wave to width between the half of difference be less than the width of U-shaped sprue on guiding device 4, more optional, the width of plate and guiding device 4 wave to width between the half of difference be less than the width of the transverse concave groove of heat transfer zone on plate.
Here can there be two kinds of set-up modes, a kind of is the direct edge near heat exchange plate by the limit of U-shaped sprue, another kind is on the both ends of guiding device 4, to hold back the first epitaxy part 43 and the second epitaxy part 44 that extend outward, preferably, in order to improve the heat exchange efficiency of plate edge, present embodiment adopts holds back the first epitaxy part 43 and the second epitaxy part 44 that extend outward on two ends of guiding device 4.Like this, the heat transferring medium that flows downward along the limit of sprue in plate edge can directly carry out heat exchange by plate.And directly by the limit of U-shaped sprue during near heat exchange plate edge, owing to being subject to stopping of guiding device 4, the heat exchange efficiency of edge is not high.So adopt and on guiding device 4, epitaxy part be set and improved heat exchange area in present embodiment, thereby improved heat exchange property.
Like this, in the runner of heat transferring medium between plate in mobile process with the runner of plate another side in another heat transferring medium carry out heat exchange.
As shown in figure 14, because in the runner of heat transferring medium between plate being flows along the transverse concave groove on the first sprue 41, the second sprue 42 and the heat transfer zone of guiding device 4, runner is simple, particularly heat transferring medium is along the streamlined flow of the first sprue 41 and the second sprue 42, and the pressure loss is little.Meanwhile, because heat transferring medium need to flow to the second sprue 42 from the first sprue 41 along the transverse concave groove of heat transfer zone, effectively utilized the heat exchange area of plate heat transfer zone, heat exchange efficiency is relatively still higher.
Figure 15 is the plate schematic diagram of the second embodiment of the present invention, and Figure 16 is plate and the guiding device 4 closed assembly schematic diagrames of the second embodiment, and Figure 17 is the local enlarged diagram of Figure 16.Below by Figure 15, Figure 16 and Figure 17, the second embodiment of the present invention is elaborated.
The difference of present embodiment and the first embodiment is, the transverse concave groove of the heat transfer zone in present embodiment on each plate is not linearity, but corrugated.Other structure of heat-exchangers of the plate type in present embodiment is identical with the first embodiment, repeats no more here.
As shown in figure 15, on the heat transfer zone 55 of plate 5, be provided with waveform transverse concave groove 551, optional, the crest of all adjacent wave shape wave transverse concave grooves 551 and trough be alignment mutually all.Wherein, the crest of the waveform transverse concave groove 551 on heat transfer zone and the quantity sum of trough are not less than the bending number of guiding device 4, and optional, the crest of the waveform transverse concave groove on heat transfer zone is identical with the bending number of the quantity sum of trough and guiding device 4.When closed assembly, the setting of aliging with the crest of waveform transverse concave groove of the first sprue 41 on guiding device 4, the setting of aliging with the trough of waveform transverse concave groove of the second sprue 42 on guiding device 4.
Certainly, those skilled in the art it should be understood that in the time of closed assembly, can be also that the first sprue 41 on guiding device 4 aligns with the trough of waveform transverse concave groove 551, and the second sprue 42 on guiding device 4 aligns with the crest of waveform transverse concave groove 551.The difference of two kinds of closed assembly modes is, when the first sprue 41 on guiding device 4 aligns with the crest of waveform transverse concave groove 551, when the second sprue 42 on guiding device 4 aligns with the trough of waveform transverse concave groove 551, heat transferring medium flow direction and heat transferring medium in the first sprue 41 are an acute angle along the angle of the flow direction of waveform transverse concave groove 551, and first sprue 41 of working as on guiding device 4 aligns with the trough of waveform transverse concave groove 551, when the second sprue 42 on guiding device 4 aligns with the crest of waveform transverse concave groove 551, heat transferring medium flow direction and heat transferring medium in the first sprue 41 are an obtuse angle along the angle of the flow direction of waveform transverse concave groove 551.
Mobile phase comparison with heat transferring medium in transverse concave groove, heat transferring medium mobile pressure drop in guiding device the first sprue is less than heat transferring medium mobile pressure drop in transverse concave groove, so heat transferring medium more easily flows in the first sprue 41 of guiding device 4, so can cause being greater than by the heat transferring medium amount of flow of transverse concave groove on bottom, heat transfer zone the heat transferring medium amount of flow on top, have the problem of the upper and lower region heat exchange of heat exchange plate inequality.
In the present embodiment, as shown in figure 17, preferably, the first sprue 41 on guiding device 4 aligns with the crest of waveform transverse concave groove 551, the second sprue 42 on guiding device 4 aligns with the trough of waveform transverse concave groove, heat transferring medium flow direction and heat transferring medium in the first sprue 41 are an acute angle along the angle of the flow direction of waveform transverse concave groove, the heat transferring medium trend that flows downward in the first sprue 41 and in waveform transverse concave groove, heat transferring medium can easierly flow into the second sprue 42 along waveform transverse concave groove in the process mobile along the first sprue 41, the heat transferring medium amount of flow that effectively solves the bottom of heat transfer zone is greater than the problem of the heat transferring medium amount of flow on top, make the heat transfer zone heat exchange of plate more even.
Like this, heat transferring medium is from the aperture as import of port zone flows into, and a part of heat transferring medium directly flows into heat transfer zone 55 downwards from port zone, and another part heat transferring medium flows into heat transfer zone 55 after by the space between drainage trough.Afterwards, owing to being provided with guiding device 4 between two adjacent plate, can be subject to stopping of guiding device 4 so enter the heat transferring medium of heat transfer zone 55, will flow downward along the first sprue 41, then, due to the obstruction of the U-shaped bending part of guiding device 4, heat transferring medium can not flow to along the first sprue 41 of guiding device 4 aperture at lower exit place.
Because the pressure in exit is less than the pressure of import department, the second sprue 42 is communicated with the aperture at lower exit place, so heat transferring medium need to be by the waveform transverse concave groove 551 on plate to the second sprue 42 that is positioned at downstream, the heat transferring medium that flows into the second sprue 42 directly flows to the aperture at lower exit place along the second sprue 42.
Because the first sprue 41 on guiding device 4 aligns with the crest of waveform transverse concave groove, the second sprue 42 on guiding device 4 aligns with the trough of waveform transverse concave groove, heat transferring medium has the trend flowing downward in the first sprue 41 and in waveform transverse concave groove, and heat transferring medium constantly flows into the second sprue 42 along waveform transverse concave groove in flowing downward in the first sprue 41.Finally, heat transferring medium all can flow out and flow to the aperture that is positioned at lower exit from the second sprue 42.
Certainly, it can also be other form that the waveform transverse concave groove of the heat transfer zone 55 on plate 5 arranges, for example, the heat transfer zone 55 of plate 5 is divided into upper and lower two parts, the crest of the waveform transverse concave groove of the first half and trough setting arrange contrary with crest and the trough of the latter half corresponding section, or, the heat transfer zone 55 of plate 5 is divided into upper, middle and lower three parts, the crest of the waveform transverse concave groove of the first half and trough setting arrange contrary with crest and the trough of point corresponding section, bottom, mid portion is the transverse concave groove of the wire in the first embodiment, or other mode, here be described no longer one by one, as long as making the uniform structure of heat transfer zone heat exchange can.And the mechanism that present embodiment adopts is simple, easy to process, is beneficial to and quantizes to produce.
The above, be only specific embodiments of the invention, not the present invention done to any pro forma restriction.Although the present invention discloses as above with preferred embodiment, but not in order to limit the present invention.Any those of ordinary skill in the art, are not departing from technical solution of the present invention scope situation, all can utilize above-mentioned announcement technology contents to make many possible variations and modification to technical solution of the present invention, or be revised as the equivalent embodiment of equivalent variations.Therefore, every content that does not depart from technical solution of the present invention,, all still belongs in the scope of technical solution of the present invention protection any simple modification made for any of the above embodiments, equivalent variations and modification according to technical spirit of the present invention.
