The specific embodiment
The first embodiment of the present invention
Now, will specifically describe the first embodiment of the present invention referring to figs. 1 to 11.
Shown in Fig. 1 to 11, comprise metal plate component with rectangular shape according to the heat exchanger plate 10 of the first embodiment of the present invention.Plate member with the irregular pattern that forms by extrusion molding (press forming) comprises projection and depression.Projection is positioned on the surface of plate member 10, thereby is located at interval in more than the first parallel longitudinal line and with different pre-determining in more than first the horizontal parallel lines that are located at interval at perpendicular to more than first parallel longitudinal line separately with predetermined.Depression is positioned on the described surface of plate member 10, thereby be arranged in more than second parallel longitudinal line and more than second horizontal parallel lines, this more than second parallel longitudinal line be from half of the distance between wherein adjacent two lines of more than first parallel longitudinal line skew, and this more than second horizontal parallel lines are from half of the distance between more than first wherein adjacent two lines of horizontal parallel lines skew.Each projection is included in its downside and has the top boss part 11 of peripheral edge and the center protrusion part 12 of extending from the peripheral edge of top boss part 11 downwards.Each depression is included in that its upside has the bottom notch part 13 of peripheral edge and from the upwardly extending intermediate recess part 14 of the peripheral edge of bottom notch part 13.
More particularly, each top boss part 11 all has truncated cone shape (truncatedconical shape), top boss part 11 is formed on the upper surface of plate member, thereby in predetermined more than the first parallel longitudinal line that is located at interval at the vertical side of the edge that is parallel to plate, and be located at interval at perpendicular to more than first parallel longitudinal line and be parallel in more than first the horizontal parallel lines of transverse side edges of plate with pre-determining separately, this pre-determining separately is longer than above-mentioned predetermined interval at interval.The top side of top boss part 11 provides circular flat zone 11a, and downside provides the curved periphery zone, its smooth center protrusion part 12 that is connected to.
Has the plate member of the irregular pattern that comprises top boss part 11 and bottom notch part 13 with respect to longitudinal centre line and cross central line symmetry.
For projection that comprises top boss part 11 and the depression that comprises bottom notch part 13, be different from the distance separately between adjacent two on the longitudinal direction of plate member, promptly less than the distance separately between adjacent in a lateral direction two of plate member.The result, projection and depression are alternately arranged the straight line on institute edge with respect to the horizontal direction of the plate member about 30 degree angles (with respect to the longitudinal direction of plate member about 60 degree angles that tilt) that tilt, thereby present the irregular pattern with the rhombus that comprises projection or depression in front view.Alternatively, can use so irregular pattern, promptly wherein plate member vertically on distance separately between adjacent two projections or the depression greater than in transversely adjacent two projections of plate member or the distance separately between the depression, perhaps can use another irregular pattern, promptly wherein plate member vertically on distance separately between adjacent two projections or the depression equal in transversely adjacent two projections of plate member or the distance separately between the depression.
Each center protrusion part 12 is all extended downwards from the following peripheral edge of each top boss part 11.As shown in Figure 4, center protrusion part 12 has flat slightly truncated cone shape, its have and the last peripheral edge of the following peripheral edge of top boss part 11 and intermediate recess part 14 between the corresponding height of distance.Each intermediate recess part 14 all extends upward from the last peripheral edge of bottom notch part 13.As shown in Figure 3, intermediate recess part 14 has flat slightly reversing truncated cone shape, its have and the following peripheral edge of center protrusion part 12 and bottom notch part 13 on the corresponding degree of depth of distance between the peripheral edge.
Center between adjacent two intermediate recess parts 14 is between adjacent two top boss parts 11 and the center between adjacent two bottom notch parts 13 between adjacent two center protrusion parts 12 and in the x wire of plate member in the vertical line of plate member.This center is positioned at center protrusion part 12 and intermediate recess part 14 centre position at the thickness direction of plate member.
Above-mentioned heat exchanger plate 10 is positioned on another heat exchanger plate that has with spline structure, their same side toward each other, and adjacent two boards at the top area 11a of top boss part 11 or the lower surface that is formed at plate member to contact with each other with the corresponding top boss part of depression 15 places, thereby formation assembled unit, then, the assembled unit of Xing Chenging has the gap with formation, i.e. the heat exchanger of passage with the same manner and the combination of other assembled units like this.Heat-exchange fluid in these passages, flow with these fluids that the upper surface of plate contacts in a kind of fluid and with these fluids that the lower surface of plate contacts in one other fluid between carry out heat exchange.Plate combination with one another by this way is integral, thereby makes protuberance contact with each other, or as required by the diffusion bonding combination, thereby gain in strength.As a result, even apply between plate in the high pressure, heat exchanger also is not easy distortion.Can prevent the variation of distance between the plate, thereby make and to handle the situation that has the immense pressure difference between the heat-exchange fluid.
In this assembled state of plate, in the gap 51 on being formed at the upper surface of plate, the center protrusion part 12 that is positioned under the top boss part 11 is separated each other toward each other and with predetermined distance, the intermediate recess part 14 that is positioned at reduced levels is separated each other toward each other and with predetermined distance, is positioned at lower level bottom notch part 13 and is separated each other toward each other and with predetermined distance.Other gap portions that place the gap portion between the center protrusion part 12 and be formed between the bottom notch part 13 form single gap 51, and it is as the passage of heat-exchange fluid.Because the existence of projection and depression, such passage comprises the expansion area and the shrinking zone of the open area with variation.These districts alternately repeat, and an end of slave plate extends to its other end.
In the gap 52 on being formed at the lower surface of plate, the rear side of the rear side of top boss part 11, center protrusion part 12 and the rear side of intermediate recess part 14 are respectively with predetermined apart from distinguishing toward each other separately.Place these separately the gap portion between the side form another single gap 52, it is as the passage of another heat-exchange fluid.Such passage also comprises alternately repeated expansion area and shrinking zone, and its end with the mode slave plate identical with above-mentioned gap 51 extends to its other end.
The degree of depth of the bottom notch part 13 of extending downwards from the height of the upwardly extending top boss part 11 of last peripheral edge of middle jut 12 and following peripheral edge from middle sunk part 14 is different, so the lower surface of the relative plate of upper surface of plate is asymmetric.Make up such plate and make its identical surface toward each other, be formed on the gap 51 and 52 that differs from one another on spatial configuration and the size.As a result, gap 52 is less than gap 51, and gap 51 provides different heat exchange characteristics with 52 according to spatial configuration and size.Consider the characteristic of two kinds of heat-exchange fluids that will use, by regulate from the height of the upwardly extending top boss part 11 of last peripheral edge of middle jut 12 and from the following peripheral edge of middle sunk part 14 downwards the degree of depth of the bottom notch part 13 of extension the spatial configuration and the size of each gap 51 and 52 are set, so that the appropriate heat transfer character that is complementary with these heat-exchange fluids to be provided.Also the universal architecture to heat exchanger carries out suitable setting, makes suitable heat-exchange fluid introducing gap separately, and these gaps have the appropriate heat transfer character at these fluids respectively.
Now, will describe the operation of heat exchanger below, be applied to this heat exchanger according to the heat exchanger plate of the first embodiment of the present invention.Confined state in heat exchanger plate 10 combinations parallel to each other, heat-exchange fluid is introduced into and 51 releases from the gap, top boss part 11 is outstanding in gap 51, another heat-exchange fluid is introduced by gap 52 simultaneously, this gap 52 is positioned at a side relative with the raised sides of top boss part 11, by with gap 52 from the gap 51 heat exchanger plates of separating 10, thereby between two kinds of heat-exchange fluids, carry out heat exchange.
Under exemplary cases, heat-exchange fluid flows according to countercurrent flow system, heat-exchange fluid flows in the channel part that is mainly limited by bottom notch part 13 and intermediate recess part 14, should flow along with top boss part 11 have the bottom notch part 13 of identical setting alignment direction separately, begin, 51 carry out from the entrance side that places the precalculated position in the gap, the top boss part is at the upper surface upper process of plate in this gap 51.
On being formed at the lower surface of plate in the gap 52 of a side relative with top boss part 11, another kind of heat-exchange fluid is mobile in the channel part that is mainly limited by the rear side of the rear side of top boss part 11 and center protrusion part 12, and the flow direction of the heat-exchange fluid in its flow direction and the gap 51 above-mentioned is opposite.As a result, heat-exchange fluid flows in gap 51 and 52 respectively, and the recurrence of laying equal stress on is loose (divergence) and compiled (confluence), thereby scatters in each zone on the apparent surface of heat exchanger plate 10.
Heat-exchange fluid scatters in each zone of plate, to improve the heat conduction between plate and the heat-exchange fluid.In addition, heat-exchange fluid flows in gap 51 and 52, this gap 51 and 52 forms between plate, and has a given shape of alternately arranging extended area and throat region, thereby for the apparent surface of every block of plate provides separately passage, this passage has the particular space structure at heat transfer character of the characteristic that has taken into full account heat-transfer fluid.Therefore can cause effective heat conduction separately between the heat-exchange fluid, thereby can between by heat exchanger plate 10 and heat-exchange fluid, carry out heat exchange reposefully, thereby significantly improve the heat exchanger effectiveness between the fluid.
Heat exchanger plate according to the first embodiment of the present invention, about irregular pattern, wherein all have the projection of top boss part 11 and center protrusion part 12 and all have bottom notch part 13 and the depression of intermediate recess part 14 regularly arranged, the official post of the degree of depth of the height of top boss part 11 and bottom notch part 13 get the reference planes of plate and be formed at plate upper surface projection to lower surface that the distance between the highest level face of upper process is different from the reference planes of plate and is formed at plate with and be formed at distance between the corresponding projection of depression of upper surface of the plate floor level face recessed down.As a result, when plate self stacked with the formation heat exchanger, according to the outstanding length of projection 11 and the recessed degree of depth of depression 13, the gap between a certain plate and the last adjacent panels was not equal to the gap between this plate and the following adjacent panels.This makes along the flow of the mobile heat-exchange fluid of this plate upper and lower surface or flow velocity significantly different each other.Two kinds of adjacent segments 51 and 52 provide the flow channel with the characteristic that differs from one another, thereby cause different heat transfer properties.The flow channel that forms according to the characteristic of heat-exchange fluid makes the heat conduction between plate and the heat-exchange fluid effectively to carry out, thereby forms effective heat exchange between fluid.In addition, the height by regulating top boss part 11 and the degree of depth of bottom notch part 13, need not to revise the basic layout of irregular pattern just can be easily and the plate freely realizing self stacking between the gap setting.Not only can realize the simple flexibly design and the manufacturing of heat exchanger, also be like this concerning plate.
The second embodiment of the present invention
Now, will specifically describe the second embodiment of the present invention referring to figs 12 to 15.
