Just as has been stated, the present invention relates to a kind of for carry out the plate of the heat exchanger of heat exchange between the first and second media.
The first and second media for heat exchange can be identical, for example gas/gas (such as air) or liquid/liquid (such as water).The first and second related media can be also two kinds of different media, for example gas/liquid or two kinds of different gas or liquid.
Especially as shown in Fig. 1-6, plate 1 has the first side A and the second side B.The first side A configuration of plate 1 has at least one heat and transmits elevated portion 2.
The first side A of plate 1 is also configured to allow the through-flow channel X(that is provided for first medium referring to Fig. 8).The second side B of plate 1 is configured to have at least one heat of the elevated portion 2 corresponding essentially on the first side A and transmits depressed part 3, be that depressed part defines the elevated portion 2 in described first side of plate, and there is substantially the same length and width, and its degree of depth equals the height of described elevated portion.Heat is transmitted through-flow channel Y(that depressed part 3 is configured to be defined for second medium referring to Fig. 7 and 8) a part.By making plate 1 stand for example punching press or perforation processing, make heat transmit elevated portion 2 and correspond to each other with heat transmission depressed part 3.If needed, can be respectively on the first side A of plate 1 and the second side B, a plurality of elevated portion 2 and corresponding depressed part 3 be set.
As particularly evident from Fig. 1,3 and 6, the first side A of plate 1 also configures has at least one heat transfer surface 4, and it transmits elevated portion 2 around heat.This heat transfer surface 4 disposes recess 5, and it allows to be provided for the through-flow channel X of first medium.Elevated portion 2 on the first side A of plate 1 defines the primary heat transfer region for first medium, and defines the secondary heat transfer area for first medium around the heat transfer surface 4 of described elevated portion.These primary and secondary heat transfer area, for example the region of described elevated portion 2 and the region sum of described heat transfer surface 4 are substantially equal to the overall area of the first side A of plate 1.Correspondingly, as being apparent that from Fig. 2,4 and 6, the second side B of plate 1 also configures has at least one mating surface 6, its corresponding to, there is identical extension with the heat transfer surface 4 on the first side A, and it correspondingly transmits depressed part 3 around heat.Depressed part 3 defines the primary heat transfer region for second medium.This primary heat transfer region, be the region that region that the region of depressed part 3 is substantially equal to described second side of plate deducts mating surface 6.According to above-mentioned, clearly, for the combination heat transfer area of first medium, be greater than the heat transfer area of second medium.When first medium has less heat transfer coefficient, such as the air with respect to water, and should be to flow than the less velocity/pressure of second medium so that when best heat transfer is provided, this feature is favourable.The heat exchanger that comprises the plate as above building will have the heat exchange performance of improvement.
Thereby, by the surface directly contacting on a kind of parts of plate of medium, provide primary heat transfer region as defined above, and the opposing surface of wherein said parts directly contacts another medium, and provide secondary heat transfer area by the surface directly contacting on a kind of parts of plate of medium, and the apparent surface of wherein said parts does not directly contact another medium.
In order to allow to be provided for the through-flow channel X of first medium, heat on the first side A of plate 1 is transmitted elevated portion 2 configurations and is had the first height h1, and recess 5 in heat transfer surface in described the first side has the second height h2, wherein h2 is greater than described the first height (especially referring to Fig. 5).Thus, recess 5 projects upwards higher than elevated portion 2.The heat corresponding to elevated portion 2 on plate 1 second side B is transmitted depressed part 3 so is configured to its degree of depth and is substantially equal to described the first height h1.Heat on plate 1 first side A is transmitted elevated portion 2 and in the illustrated embodiment of plate, is equipped with additional recess 7, to allow to be provided for the through-flow channel X of first medium.For this purpose, these additional recesses 7 are greater than described the first height with (first) height h1 sum of elevated portion 2.In the embodiment shown, the height h1 of the height of recess 7 and elevated portion 2 is substantially equal to the second height h2, the height of the recess 5 in instant heating transfer surface 4.Thereby the height of recess 7 is that h2 deducts h1.According in the described embodiment of the plate of Fig. 1-8, heat transmission elevated portion 2 on the first side A of plate has the first height h1 of the about 0.5-1 millimeter of the hot transfer surface 4 of distance, and corresponding heat transmission depressed part 3 on the second side B of plate has the degree of depth that is substantially equal to described the first height apart from mating surface 6, and recess 5 in the hot transfer surface of side A has the second height h2 of the about 2-2.5 millimeter of the described hot transfer surface of distance.Yet these highly can and will use the size of the heat exchanger of plate to change according to the application of expection therein.Can prepare in any suitable manner the recess 5 and 7 on the first side A of plate 1, punching press and the puncture of for example by being similar to heat, transmitting elevated portion 2/ depressed part 3 are processed, thereby on the second side B of plate, in mating surface 6 and depressed part, form respectively corresponding depressed part, and there is described elevated portion/depressed part simultaneously.The pattern of size, shape and the quantity of recess 5,7 and their settings also can change according to the size of desired application and heat exchanger.Plate 1 is larger, provides distance and the strong point to allow to be provided for the recess more than 5,7 of the through-flow channel X of first medium needs.Yet, it should be emphasized that, according to the present invention, can also be only by means of the recess 5 in heat transfer surface 4 or only transmit by means of heat the through-flow channel X that recess 7 in elevated portion 2 can allow to be provided for first medium.In an illustrated embodiment, recess 5,7 is circular substantially.
Shape, size, quantity and position that the heat transmission depressed part 3 of a part of the upper through-flow channel Y for second medium of the second side B of limiting plate and the corresponding heat on the first side A of plate are transmitted elevated portion 2 can change.Therefore, depressed part 3 and corresponding elevated portion 2 can be for example U-shapeds, comprise two straight, parallel or substantially parallel parts.Yet, in order to extend the heat exchanger time between the first and second media, depressed part 3 and corresponding elevated portion 2 can alternately have sinusoidal shape substantially, it has three or more straight, parallel or substantially parallel part, i.e. straight, the parallel or substantially parallel part of odd number (referring to Figure 10) or (referring to Fig. 1-8) even number.In order to maximize the heat exchange between the first and second media, advantageously, if the heat transfer area of depressed part 3 and corresponding elevated portion 2 is large as far as possible with respect to the volume of the through-flow channel Y for second medium.Therefore, the width w of depressed part 3 and corresponding elevated portion 2 is greater than the degree of depth of described depressed part and the corresponding height of elevated portion in the embodiment shown substantially, and for example large 5 times, and preferably in the embodiment shown, approximately 50-70 is doubly.Therefore, to have the first height h1 be about 0.5-1mm, heat transmits elevated portion 2 and have the corresponding heat that the degree of depth equals described the first height transmits in the illustrated embodiment of depressed part 3, the width w of elevated portion and respective recesses portion will be at least about 2.5mm, and preferred about 25-70mm.The width w of depressed part 3 and corresponding elevated portion 2 can be constant, or can change along its length, especially as shown in Fig. 1-4,6 and 10.In Fig. 1-4,6 and 10, first the width w that shows straight parallel portion reduces, and increases back its original width subsequently.Thereby if the first height h1 and respective depth are about 0.5mm, the width w that heat is transmitted elevated portion 2 and corresponding heat transmission compression unit 3 can be reduced to about 25mm from about 35mm, and is increased to about 35mm subsequently again.At depressed part 3, is connected the part place of its straight parallel portion with corresponding elevated portion 2, width w is far smaller than described straight portion office, is greater than in the embodiment shown the first h1 and corresponding to its approximately 20 times of the degree of depth highly.Similarly, in having the illustrated embodiment of rectangular slab 1, depressed part 3 and corresponding elevated portion 2 can be equipped with straight parallel portion, and it is advanced along the horizontal direction that longitudinally or substantially becomes that is transverse to plate.If needed, described straight parallel portion can plate 1 longitudinally on or in other required directions, alternately advance arbitrarily.
In order to prevent from compressing the through-flow channel Y of second medium, the heat on plate 1 second side B is transmitted depressed part 3 and is disposed resistance to compression recess 8.These resistance to compression recesses 8 are highly substantially equal to described the first height h1 in the embodiment shown, instant heating transmits the height of elevated portion 2, therefore and equal the degree of depth that heat is transmitted depressed part, thereby these recesses 8 finish in the outstanding same level of depressed part substantially.The horizontal plane identical by the mating surface 6 on the second side B with plate 1 finishes, described recess 8 can mesh the corresponding recess in another plate second side, to prevent from compressing the through-flow channel Y of second medium, and can contribute to safe by described recess is bonded to each other in the mode of matching and effectively the second side of described the second side and described other plates be assembled.By form turbulent flow in described flowing, recess 8 also promotes second medium to flow through through-flow channel Y, thereby has improved heat exchange effect.Yet if needed, the height of recess 8 can be less than described the first height h1.In an illustrated embodiment, recess 8 has circle and elongated shape.Some elongated recesses or bending.Recess 8 can also be set to the pattern of any appropriate, for optimization heat exchange effect.
In an embodiment who schematically shows at Figure 11, resistance to compression recess 8 is elongated, and transmit depressed part 3 extension that tilts in heat, preferably parallel to each other, and when the second side B of two boards 1 is together time, tilt by the through-flow channel Y of second medium, the preferred whole width of logical heat transfer depressed part/through-flow channel, and described elongated recess described heat transmit depressed part/through-flow channel longitudinally on be spaced apart from each other.Heat is transmitted some required some bifurcated that elevated portion 2/ depressed part 3 can be between elongated recess 8, and gang more at once subsequently, so that to the recess 5 extending from heat transfer surface 4 but not transmit from heat the recess 7 that elevated portion 2 extends space is provided, thereby, on the first side A of plate 1, only there is having the recess of the second height h2.Elongated recess 8 preferably has leg-of-mutton cross section substantially, but also can have other required cross sections arbitrarily, the example cross section of conical butt substantially as shown in figure 11.Recess 8 is arranged so that when the second side B of two boards 1 is adjacent to each other together, and described recess intersects advances, preferably rectangular each other, and a plurality of points for meshing are provided, and described recess can be assembled each other.
On the relative first side A of plate 1, thereby heat is transmitted elevated portion 2 by the elongated recess 8 in the heat transmission depressed part 3 on the second side B of plate and interrupts, described recess transmits in heat " groove " 8a that limits corresponding configuration in elevated portion thus, and it forms a part of the through-flow channel X of first medium.Therefore, these " grooves " 8a transmits elevated portion 2 updips in heat and tiltedly extends, and preferably from a side to opposite side, and is spaced apart from each other, and defines betwixt " rib-like " part 2a that heat is transmitted elevated portion.As described above, some such " rib-like " part 2a interrupt, and preferably in the central authorities of its longitudinal extension part, think that recess 5,6 provides space.As from Figure 11 clearly, the impression that this embodiment provides is, more appropriate is thinks that the heat of the first side A of plate 1 transmits elevated portion and comprise that a plurality of independently heat elongated, parallel and that tilt to extend transmits elevated portion, and what advance therebetween is the part (8a limits by " groove ") of heat transfer surface 4.
Above-mentioned and provide the strong through-flow channel Y that is used in particular for second medium as the embodiment being schematically shown in Figure 11, but according to above clearly, if needed, elongated recess 8 also can relative to each other extend with non-parallel direction, and the recess 7 that transmits " rib-like " part 2a extension of elevated portion 2 from heat can be provided.
In order to promote that by strengthening through-flow channel first medium flows through through-flow channel X and prevents that it from subsiding, the heat transfer surface 4 on the first side A of plate 1 is equipped with in a similar manner strengthens recess 9.These are strengthened recesses 9 and are highly substantially equal in the embodiment shown described the first height h1, and instant heating transmits the height of elevated portion 2, thus recess substantially with elevated portion 2 in same horizontal plane.Yet what need is that the height of recess 9 is less than described the first height h1, and preferably as far as possible little, so that minimize the mobile pressure drop of first medium in through-flow channel X, and still maintain the strengthening performance of recess.The height of recess 9 can also be greater than described the first height, as long as it does not exceed (second) height h2 of recess 5.In the embodiment shown, recess 9 has elongated shape.Recess 9 can also be set to the pattern of any appropriate, for optimization heat exchanger effectiveness.
