Description

The present invention relates to a humidifying device for transmitting water vapor according to the preamble of claim 1. The present invention further relates to a method for operating a humidifier, and an automobile having such a humidifier.

Humidifiers for transferring water vapor from one fluid flow to another have long been known in the automotive field, but are of particular importance for their use in relation to driving fuel cells. In order to achieve both optimum power yield and relatively long service life / life, the operating temperature of a fuel cell used to drive an automobile is generally up to 80 ° C.

As a result of the relatively high operating temperature, the fuel cell during driving operation of the vehicle remains relatively moist due to its function, for example if the fuel cell is a proton exchange membrane (PEM) or polymer electrolyte membrane. There is a need. Otherwise, the membrane used in the fuel cell may dry out completely. Such complete drying has a particularly adverse effect on the service life / life of the membrane used and the efficiency of the fuel cell.

It is known that a fuel cell is kept moist by increasing the amount of water contained in the reaction gas passed through the fuel cell to a sufficient extent. This can be achieved, for example, with a humidifier integrated into the fuel cell. For example, a conventional humidifier known conventionally, such as the humidifier for a fuel cell system described in Patent Document 1, has a plate laminate composed of individual plates and has two or more fluids of a fluid channel system. Channels penetrate the plate laminate. Fluid channels are routed within the plate stack so that water and / or water vapor can move from one fluid flow to another. In particular, membrane plates that do not allow air to permeate but allow water and water vapor to permeate are placed between the fluid channels. Through the membrane plate, water and / or water vapor can be transferred from one fluid flow to another. This occurs, for example, when the fluid flow to be humidified flows over one side of the membrane plate and the wet fluid flow flows over the other side. Since the two fluid flows are fluidly separated from each other by the membrane plate, no substantial mixing of the two fluid flows occurs.

DE 11 2012 000 477 T5

The fact that the plate laminate must be sealed to the periphery is considered to be a disadvantage of known solutions. Since the fluid flowing through the fluid channel is generally under high operating pressure (eg, up to 2.0 bar for an ambient pressure of 1013.25 hPa), all plates of the plate laminate are sealed with the encapsulant used. In order to secure or improve the stopping effect, it is additionally necessary to tighten each other with a relatively large tightening force. In known humidifiers, this increases flow resistance and thus impairs the efficiency of the humidifier.

Therefore, it is an object of the present invention to provide an improved embodiment or at least another embodiment of a humidifying device.

In the invention, this object is solved specifically by the subject matter of the independent claims. A favorable embodiment is the subject of the dependent claims and the specification.

The basic idea of the present invention is to reduce the tightening force for tightening the plates to each other, thereby having a positive effect on the flow resistance in the plate laminate. Here, the present invention utilizes an innovative finding that the required tightening force depends on the amount of pressure gradient generated during the operation of the humidifier. It is established that the smaller the pressure gradient during operation of the humidifier, the smaller the tightening force for tightening the plates to each other can be selected.

Against this background, the present invention provides to reduce the pressure gradient in the humidifier. For this purpose, the humidifier comprises a humidifier. The humidifier has a plate laminate, two housing connectors each located on the front side of the plate laminate mounting surface of the plate laminate, and a fluid channel system. Further, the plate laminate defines a major axis along its main extension direction. The long axis can define, for example, the alignment direction in which one or more or more plates or groups of plates stacked in contact with each other to form a plate laminate are provided. However, in each case, the plate laminate is further placed within the fluid channel housing of the humidifier, especially completely inside. Since the fluid channel housing is in fact pressurizable or depressurized, the pressure difference or pressure gradient between the fluid channel housing and the rest of the fluid channel system can be freely adjusted. Thereby, for example, a relatively small pressure difference or a relatively small pressure gradient can be adjusted, so that a smaller force can be selected as the tightening force for tightening the plate laminate, and as a result, in the plate laminate. Has a positive effect on the flow resistance of. This has the advantage that the entire humidifier can be operated more energy-efficiently, and thus more cost-effectively, and more environmentally friendly.

In practice, the fluid channel housing is removable or non-removable and is placed in contact on the two housing connectors. Here, it is clear that the fluid channel housing can be formed substantially integrally with the housing connector integral part, i.e., the housing connector, forming the fluid channel housing-housing connector component as a whole. However, in practice, the fluid channel housing can also be formed as a separate component and placed on the housing connector by any fastening means, such as fastening screws and / or adhesives. be. For example, the fluid channel housing can be placed between the housing connectors as an insert and fastened axially along the longitudinal axis between the housing connectors to permanently secure the fluid channel housing to the housing connector. This has the advantage that the humidifier can be more preferably made. Further, in practice, fluid pressure can be applied to the fluid channel housing by the fluid channel system or the pressure supply device of the humidifier to affect the pressure difference in the fluid channel system. This has the advantage that the pressure difference or pressure gradient between the fluid channel housing and the rest of the fluid channel system is adjustable.

In practice, a fluid channel system comprises one or more fluid channels formed between one plate laminate and the other fluid channel housing, through which the fluid channel is a first fluid flow or a second fluid flow. A fluid flow flows. Therefore, a fluid such as a compressible processing gas charged with the liquid can flow through the fluid channel housing. Further, in practice, the void flow cross sections of the fluid channels, laterally arranged along the major axis, are ranged between one plate laminate and the other fluid channel housing. In particular, the flow section completely encloses the plate laminate laterally to all sides with respect to the major axis, i.e., over the entire circumference. This has the advantage that pressure can be evenly applied to the plate laminate from all sides and, as a result, the energy efficiency of the humidifier is further improved. In addition to this, in practice, a constant spacing can be defined between the plate laminate and the fluid channel housing laterally with respect to the major axis over the entire circumference. This has the advantage that the plate laminate does not come into contact with the fluid channel housing.

In practice, one or more drain channels may be provided on the fluid channel housing. Each discharge channel has the function of discharging a fluid such as a leaking fluid or another fluid originating from a plate laminate. Here, the drain channel preferably extends along the fluid channel housing, eg, along the long axis of the fluid channel housing. Here, the drain channel can project laterally across the fluid channel housing with respect to the major axis to form a drain channel protrusion. In this regard, the drain channel also defines a major axis of the drain channel along its main extension direction and the drain channel can be placed on the fluid channel housing at an angle. For example, the discharge angle is formed between the major axis and the major axis of the discharge channel. For example, the discharge angle is 0.1 to 5 °, and the discharge angle is 0.1 °, 0.5 °, 1.0 °, 1.5 °, 2.0 °, 2.5 °, 3. 0 °, 3.5 °, 4.0 °, 4.5 °, 5.0 °. This has the advantage that the leaking fluid automatically flows out of the humidifier and enters, for example, a leaking fluid reservoir located on the fluid channel housing. Here again, the entire housing can be placed at an angle with respect to the direction of gravity. The angles are, in particular, 0.1 °, 0.5 °, 1.0 °, 1.5 °, 2.0 °, 2.5 °, 3.0 °, 3.5 °, 4.0 °. , 4.5 °, 5.0 °. In addition, there may be one or more drainage connections on one or both housing connectors capable of draining the leaking fluid. The discharge connection allows the discharge of a fluid that can be, for example, a liquid or a gas, such as a discharge fluid. Since the discharge connection is, for example, in the form of a connector, it may be conceivable that, for example, a hose or the like can be fixed to the discharge connection.

Alternatively, the drain connection can also be placed directly, especially in contact, on the housing.

In practice, the fluid channel housing further has a first fluid channel construct and a second fluid channel construct that both extend through the plate laminate, in particular completely penetrate the plate laminate. Here, the first fluid channel construct and the second fluid channel construct move water and / or water vapor from the first fluid stream to the second fluid stream, eg, via the membrane plate described below. For transmission, they may be interconnected and interconnected within the plate laminate. The first fluid channel construct or the second fluid channel construct is in fact communicatively connected to the fluid channel to achieve pressurization of the fluid channel housing.

Further, the first fluid channel construct may comprise one or more first plate laminate fluid channels and a second plate laminate fluid channel extending in the longitudinal direction through the plate laminate. The first plate laminate fluid channel is interconnectably connected to the second plate laminate fluid channel via at least one first cross-flow passage. Further, in practice, the second fluid channel construct comprises one or more first functional fluid channels and a second functional fluid channel extending in the longitudinal direction through the plate laminate. The first functional fluid channel is interconnectably connected to the second functional fluid channel via at least one second interflow passage. Thus, the first fluid flow and / or the second fluid flow can flow through the humidifier. In addition, the first functional fluid channels, individually or together, were ranged between the fluid channel housing and the plate laminate via at least one mouse opening in the plate laminate. It is interconnectably connected to the fluid channels of a fluid channel system and can apply pressure, especially internal pressure, to the fluid channel housing.

The plate laminate may include, in particular, a plurality of laminates laminated in contact with each other in the alignment direction. Each laminate group is actually a plurality of plates loaded in contact with each other, that is, at least one interflow plate and at least one air or gas impermeable, water and water vapor permeable membrane plate. It has at least one mouse plate. For example, during the operation of the humidifier, the laminates may be, strictly speaking, an interflow plate, a membrane plate placed in contact with the interflow plate, and a mouth plate placed in contact with the membrane plate. It is possible to include a membrane plate placed in contact with the mouse plate. As a result, a relatively efficient layered body group is specified. With this group of laminates, the fluid channel can be relatively suitably pressured to allow fluid to flow through the plate laminate.

The interflow plate is formed, for example, by a flat body having a flat and wide front surface and a flat and wide rear surface facing away from the front surface. The flat body has recesses that form a first interflow passage. The recess completely penetrates the flat body from its wide front surface to its wide rear surface, thus forming a flat body frame as a whole. Here, the flat body frame actually has a first aisle structure and a second aisle structure. The first passage construct and the second passage construct each form a flat body frame, forming a first plate laminate fluid channel and a second plate laminate fluid channel from a wide front surface to a wide rear surface. Penetrates into, especially completely. In either case, the flat frame actually comprises a third aisle construct. The third passage construct, in all cases, completely penetrates the flat frame from the wide front surface to the wide rear surface to form the first functional fluid channel. Here, since the first passage structure and the second passage structure are connected to each other so as to be able to communicate with each other via the first flow passage, the first fluid flow or the first fluid flow is used during the operation of the humidifying device. The second fluid flow can flow from the first plate laminate fluid channel to the second plate laminate fluid channel and vice versa.

The mouse plate is actually formed by a flat mouse body. The flat mouse body has a wide front surface and a flat and wide rear surface facing in the opposite direction of the front surface. The flat mouse body may further include a recess forming a second interflow passage. This recess penetrates the flat mouse body from the wide front to the wide back, especially completely. Therefore, a flat mouse body frame is formed. In either case, the flat mouse body frame may comprise a first passage construct and a second passage construct. The first passage construct and the second passage construct are flat mouse bodies, forming the first plate laminate fluid channel and the second plate laminate fluid channel from the wide front surface to the wide rear surface in each case. Completely penetrates the frame in all cases. The flat mouse body frame may comprise a third passage construct and at least one mouse opening. The third passage construct penetrates the flat mouse body frame while forming the first functional fluid channel. The mouse opening substantially forms an opening in the flat mouse body frame towards at least one side while forming an opening in the fluid channel. Thus, the first fluid flow and the second fluid flow can flow from the third passage construct to the fluid channel and vice versa.

The first, second, and third passage configurations can each be formed by at least one recess. Each individual recess has a circular, oval, or rectangular void flow cross section so that fluid can flow through the recess.

In practice, each housing connector has a first fluid connection and a second fluid connection, respectively. The first fluid connection of the first housing connector and the first fluid connection of the second housing connector are actually fluidly connected to the first fluid channel construct. The second fluid connection of the first housing connector and the second fluid connection of the second housing connector are fluidly connected to the second fluid channel construct.

Here, it is conceivable that the fluid channel housing may be removably or non-removably fastened to the housing connector by fastening screws or adhesive. Alternatively, one or both housing connectors may be integrally molded onto the fluid channel housing. In either case, the fluid channel housing allows the plate laminate disposed within the fluid channel housing to be pre-defined by the fluid channel housing via the housing connector disposed on the fluid channel housing. Since it only does, the function of a fixed stopper (stop) can be assumed.

The present invention comprises a further idea to provide a method for operating a humidifier, particularly a humidifier having the above characteristics. Within the scope of this method, a step of providing and introducing a first fluid flow and a second fluid flow into the humidifier is first provided. Following this, a step of providing a first pressure level into the first fluid channel construct, a step of providing a second pressure level to the second fluid channel construct, and a third pressure level of the fluid. The process of providing in the channel housing is performed. However, the third pressure level is between the normal pressure of 1013.25 hPa and the first or second pressure level, or the third pressure level is the first pressure level and the second pressure level. Or the third pressure level is either higher than the normal pressure of 1013.25 hPa and higher than the first pressure level and / or higher than the second pressure level. .. This achieves the ability for the humidifier to operate relatively energy efficiently, as the pressure difference between the first and second fluid constructs and the fluid channel housing is minimized in all cases. To. As a result, there is an advantage that the pressure difference in the humidifier is lower than that of the conventionally known humidifier.

The present invention comprises the further idea of equipping the vehicle with a humidifying device for transmitting water and / or water vapor from a first fluid stream to a second fluid stream. For this purpose, a humidifier with a plate laminate, two housing connectors each located on the front side of the plate laminate equipment surface of the plate laminate, and a fluid channel system is proposed. The plate laminate comprises a plurality of laminates laminated in contact with each other in an alignment direction defining a major axis. The fluid channel system comprises at least two fluid channel constructs. The first fluid channel construct comprises a plate laminate fluid channel extending along the longitudinal direction through the laminate plate. The second fluid channel construct comprises a functional fluid channel. The functional fluid channel comprises a functional fluid channel plate laminate passage extending in the longitudinal direction through the laminate plate and a functional fluid channel housing passage connected to the functional fluid channel plate laminate passage. Here, the functional fluid channel plate laminate passage and the plate laminate fluid channel are interconnectably connected to each other within the laminate plate for transmitting water and / or water vapor. Here, the laminate plate is placed in or completely inside the functional fluid channel housing aisle, and at least one laminate plate opens towards the functional fluid channel housing aisle and the functional fluid channel plate laminate It is essential to create a fluid connection between the passage and the functional fluid channel housing passage.

In practice, the membrane plate is particularly impermeable to air, is water and water vapor permeable, and / or is formed from a round, oval, or polygonal flat membrane. The flat membrane has a flat and wide front surface and a flat and wide rear surface facing in the opposite direction of the front surface. For example, the membrane plate is a first fluid flow to a second fluid channel construct that flows through the first fluid channel construct between the interflow passage and the mouse flow passage during the operation of the humidifier. Arranged to transfer water and / or water vapor to a second fluid stream flowing through.

In summary, the present invention relates to a humidifying device for transmitting water and / or water vapor from a first fluid flow to a second fluid flow. For this purpose, the humidifier is a humidifier with a plate laminate that defines a major axis along the main extension direction and, in all cases, placed in front of the plate laminate equipment surface of the plate laminate 2 It has two housing connectors and a fluid channel system. The present invention is essentially that the plate laminate is placed within the fluid channel housing.

More important features and advantages of the invention are derived from the dependent claims, drawings, and the description of the relevant figures with the drawings.

It should be noted that the above features and the features described below may be used not only in the respective combinations described, but also in other combinations or themselves without departing from the scope of the present invention.

Preferred exemplary embodiments of the invention are shown in the drawings and will be described in more detail below. The same reference numeral refers to a component having the same or similar function or the same function.

The drawings are exemplary in all cases.

FIG. 1 is a perspective view of the humidifying device. FIG. 2 is a diagram showing the humidifier of FIG. 1 with the fluid channel housing removed so that the plate laminate tightened between the two housing connectors can be better seen. FIG. 3 is a cross-sectional view of the humidifying device of FIG. 1 along the cutting line III-III of FIG. 1, showing a plate of a plate laminate of the humidifying device, that is, a mouse plate. FIG. 4 is a plan view showing a further plate of the plate laminate of the humidifier of FIG. 1, i.e., an interflow plate. FIG. 5 is a plan view showing a further plate of the plate laminate of the humidifier of FIG. 1, i.e., a membrane plate.

FIGS. 1 to 5 show the entire humidifying device 1. The humidifying device 1 has a function of transmitting water and / or water vapor from the first fluid flow 2 to the second fluid flow 3. For this purpose, the humidifier 1 includes a humidifier 4 and a fluid supply device (not shown) connectable to the humidifier 4 for supplying the fluid to the humidifier 4. In the field of automobiles, the humidifying device 1 has, for example, a function of keeping a fluid passed through a fuel cell relatively moist. In the following description, individual figures will be referred to.

In FIG. 1, it can be seen that the humidifier 1 actually includes the humidifier 4. The humidifier 4 includes, for example, a plate laminate 7 shown in FIG. 2, two housing connectors 9 and 10 arranged on the front side of the plate laminate equipped surface 8 of the plate laminate 7, and a fluid channel shown in FIG. Equipped with a system. The humidifier 4 extends along the main extension direction 5, and a major axis 6 and a horizontal axis 55 lateral to the major axis 6 are defined along the main extension direction 5. The major axis 6 and the horizontal axis 55 are shown by broken lines in FIGS. 1 and 2, respectively. The humidifier 4 has a fluid channel housing 12 that completely surrounds the plate laminate 7. The fluid channel housing 12 is preferably a thin-walled component. This thin-walled component may be configured as a single body or may be composed of a plurality of parts. The fluid channel housing 12 is preferably made of a plastic material, a metal material, or a composite material.

In FIG. 1, it can be further seen that the first housing connector 9 and the second housing connector 10 are arranged on the plate laminated body mounting surface 8 of the plate laminated body 7. Each housing connector 9, 10 has, for example, a rectangular parallelepiped shaped substrate, preferably made of a plastic material, a metal material, or a composite material. Further, the housing connectors 9 and 10 connect a fluid conduction fluid line, particularly with a reinforcing portion for reinforcing each substrate, and a connecting means for connecting each substrate to the fluid channel housing 12 and / or another substrate. It is provided with a connection part for making a connection. The first housing connector 9 and the second housing connector 10 shown in FIG. 1 have two connecting portions (first and first) having a function of introducing or discharging a first fluid flow 2 and a second fluid flow 3, respectively. 2. The fluid connection portions 53 and 54) are provided. In FIG. 1, the fluid flows 2 and 3 are indicated by arrows, respectively. Of course, the direction of the flow shown in the figure may be reversed or may be directed in the same direction.

In FIG. 1, it can be seen that the discharge channel protrusion 17 is arranged on the fluid channel housing 12. Further, the draining fluid or the leaking fluid may be drained from the humidifier 1 through the drain channel protrusion 17. The discharge channel 16 ranged by the discharge channel protrusion 17 or the discharge channel protrusion 17 shown in FIG. 3 defines the discharge channel major axis 18 along its main extension direction. In FIG. 1, the discharge channel major axis 18 is indicated by a broken line. Since the discharge angle 19 is ranged between the discharge channel major axis 18 and the major axis 6, the discharge channel protrusion 17 is disposed on the fluid channel housing 12 at a substantially certain angle. The discharge angle 19 is, for example, 1 ° or any other acute angle. It is pumped out via the drainage connection 56 located on the first and / or second housing connectors 9, 10 where the drainage fluid or leaky fluid is automatically drained from the drainage channel protrusion 17. It has the effect of being able to be pumped or discharged.

In FIG. 2, since the fluid channel housing 12 is removed, the plate laminate 7 of the humidifier 4 can be seen. The plate laminate 7 extends along the long axis 6. The plate laminate 7 has a plurality of plates 31. The plurality of plates 31 are laminated in contact with each other in the alignment direction 29 parallel to the major axis 6, and are connected, for example, with a sealing material and / or a sealing paste (not shown) in the middle. As described above, the plate laminate 7 defines a total of two plate laminate mounting surfaces 8 at its free front end. The housing connectors 9 and 10 are arranged on the mounting surface 8 of the two plate laminates. The plate 31 of the plate laminate 7 may form, for example, a plurality of laminate groups 30. Each of the plurality of laminated body groups 30 is composed of different plate types 31. For example, one or more laminate groups 30 are provided, each laminate group 30 is composed of an interflow plate 32, a membrane plate 33, a mouse plate 34, and / or other plates described in more detail below. To.

In either case, FIG. 2 further shows the fluid channel system 11 penetrating the plate laminate 7. For example, the fluid channel system 11 comprises first and second fluid channel constructs 20, 21. The first and second fluid channel configurations 20, 21 have the function of passing the fluid from the fluid connection portions 53, 54 to the other fluid connection portions 53, 54, respectively. The first fluid channel construct 20 comprises, for example, one or more plate laminate fluid channels 22 and 23 extending in the direction of the major axis 6 through the plate laminate. The second fluid channel configuration 21 comprises, for example, one or more functional fluid channels 25 that also extend in the direction of the major axis 6 through the plate laminate 7. The plate laminate fluid channels 22 and 23 and the functional fluid channel 25 are located relatively close to each other in the plate laminate 7 and are simply separated by the membrane plate 33 so that water and / or water vapor is the first fluid. It can be transmitted from the stream 2 to the second fluid stream 3 via the membrane plate 33.

FIG. 3 shows a cross-sectional view taken along the cutting line III-III of the humidifier 1 or the humidifier 4 of FIG. The cross-sectional view shows the two plates 31, ie the mouse plate 34 of the laminate group 30, the membrane plate 33 of the same laminate group 30, and the discharge channel 16 ranged by the fluid channel housing 12. Further, a horizontal axis 55 introduced in FIG. 1 and a vertical axis 57 orthogonal to the horizontal axis 55 are shown. The discharge channel protrusion 17 can be seen on the fluid channel housing 12. The discharge channel protrusion 17 projects in the direction of the horizontal axis 55 so as to be away from the plate laminate 7, and defines the discharge channel 16. The fluid channel 13 of the fluid channel system 11 through which the first fluid flow 2 or the second fluid flow 3 can flow is ranged between the plate 31 and the fluid channel housing 12. The fluid channel 13 defines a void flow cross section 14. The flow cross section 14 is configured to surround the plate 31 in the direction of the horizontal axis 55 and the vertical axis 57, i.e., toward all sides, to form a complete island. Here, since a constant interval 15 is defined between the plate 31 and the fluid channel housing 12 over the entire circumference, the fluid channel housing 12 is arranged without contacting the plate 31 and also in the humidifying device 1. During operation, it does not hit the plate due to vibration.

The mouse plate 34 shown in FIG. 3 has a flat mouse body 43. The flat mouse body 43 includes a flat and wide front surface 44 and a flat and wide rear surface 45 facing in the opposite direction of the front surface 44. The flat mouse body 43 further has a central, particularly large area, recess 38. The recess 38 forms a so-called second flow passage 27. The second interflow passage 27 starts from the wide front surface 44 and extends to the wide rear surface 45, and completely penetrates the flat mouse body 43 while forming the flat mouse body frame 46. For example, the flat mouse body frame 46 has a base 60 and two legs 58, 59 disposed on the base 60. The flat mouse body frame 46 further comprises first and second passage constructs 47, 48. The first and second passage constructs 47, 48 completely penetrate the flat mouse body frame 46 while forming the first and second plate laminate fluid channels 22, 23. In addition to the first and second passage configurations 47, 48, the flat mouse body frame 46 further comprises a third passage construct 49 and at least one mouse opening 28. The first passage construct 49 completely penetrates the flat mouse body frame 46 while forming the first functional fluid channel 25. Since the mouse opening 28 opens the flat mouse body frame 46 toward at least one side while forming the opening 51 with respect to the fluid channel 13, the first or second fluid flow 2, 3 is the third. It is possible to flow from the passage structure 49 through the second interflow passage 27 to the fluid channel 13 and vice versa. When flowing through the second interflow passage 27, for example, water and / or water vapor may be transmitted through the membrane plate 33. Each of the passage constructs 47, 48, 49 or the plate laminate fluid channels 22, 23 and the functional fluid channel 25 has a void flow cross section 52.

The orientation of the channels shown in FIG. 3 does not correspond to the actual installation position in any case. Preferably, since the discharge channel 16 is downward, especially in the direction of gravity, any fluid separated in the discharge channel 16, especially water, collects in the discharge channel 16 and is discharged. Apart from this, the humidifying device 1 can also be installed at an angle, especially with respect to the direction of gravity, so that water can be discharged in the direction of gravity.

FIG. 4 shows two plates 31, namely the interflow plate 32 and the membrane plate 33 located behind the interflow plate 32. The membrane plate 33 is arranged in contact with the interflow plate 32. In reality, the interflow plate 32 is formed by the flat body 35. The flat body 35, like the mouse plate 34, has a flat and wide front surface 36 and a flat and wide rear surface 37 facing in the opposite direction of the front surface 36. The flat body 35 also has a central, particularly large area, recess 38. The recess 38 extends from the wide front surface 36 to the wide rear surface 37, completely penetrates the flat body 35 while forming the flat body frame 39, and forms the so-called first interflow passage 24. The flat frame 39 is similarly penetrated by the first and second passage constituents 47, 48, and the flat frame 39 comprises two plate laminated fluid channels 22, 23. The flat frame further has a third passage construct 49. The third passage structure 49 penetrates the flat frame 39 while forming the functional fluid channel 25. In either case, the first and second passage configurations 47, 48 can communicate with each other via the first interflow passage 24. Therefore, the fluid can flow from one plate laminate fluid channel 22 to the other plate laminate fluid channel 23. When flowing through the first interflow passage 24, water and / or water vapor may be transmitted, for example, via the membrane plate 33.

According to FIG. 5, an additional plate 31, i.e., a membrane plate 33, is visible. The membrane plate 33 is particularly impermeable to air, is water and water vapor permeable, and / or is formed by a round, oval, or polygonal flat membrane 61. The flat film body 61 has a flat and wide front surface 62 and a flat and wide rear surface 63 facing in the opposite direction of the front surface 62. For example, the membrane plate 33 has a first fluid flow 2 to a second fluid flow that flows between the interflow plate 32 and the mouth plate 34 through the first fluid channel structure 20 during the operation of the humidifying device 1. Arranged to transfer water and / or water vapor to a second fluid stream 3 flowing through the fluid channel construct 21. The membrane plate 33 separates the first and second flow passages 24, 27 from each other. The membrane plate 33 further comprises three passage constructs 47, 48, 49.

During operation of the humidifier 1, the plates 31 are in contact with each other and are arranged in particular congruently to form the plate laminate 7. The respective passage constructs 47, 48, 49 of the plate 31 are stacked and laminated together in tandem with each other, and together, the plate laminate fluid channels 22, 23 and the second fluid channel of the first fluid channel construct 20 are stacked. The functional fluid channel 25 of the structure 21 is formed.
