Description
Technical Field
The present invention relates to a temperature control assembly, in particular for a vehicle seat of a motor vehicle, and to a vehicle seat comprising such a temperature control assembly.
Background
The seating area of a vehicle seat of a modern motor vehicle is usually temperature-controlled by means of cooled or heated air. However, in the case of such conventional temperature control assemblies, it is generally relatively complicated from a technical point of view to guide air to or from the seating area, and thus the production cost is high.
Disclosure of Invention
It is therefore an object of the present invention to show a new method for developing a temperature control assembly which is simple to construct from a technical point of view and is therefore cost-effective.
This object is solved by the subject matter of the independent claims. Preferred embodiments are the subject of the dependent claims.
The basic idea of the invention is therefore to temperature control a surface, in particular a surface of a vehicle seat, by means of a thermoelectric device which is thermally connected to said surface via a mechanically flexible heat conducting unit comprising at least one heat conducting element made of a heat conducting material. Particularly preferably, the material is a metal, so that the mechanically flexible heat-conducting element can be formed by a metal wire or a metal wire. Thus, the thermoelectric device forming the heat source or the heat sink can be arranged at a distance from the temperature control assembly, since the thermal coupling can take place via one or more of such heat conducting elements. If the surface to be temperature controlled is a seat area of a vehicle seat, an unnecessary reduction of the seat comfort, which may occur if the thermoelectric device is arranged directly in the seat area, can be counteracted by arranging a typical mechanically rigid thermoelectric device at a distance from the seat area interacting with the mechanically flexible heat-conducting element.
Independently of this, the heat conducting element described herein (which is essential to the invention) provides a flexible transition from a rather point-like heat source or heat sink (thermoelectric device) to surface cooling. The above-described implementation of a technically relatively complex fluid path for conducting air as a temperature control medium can therefore be dispensed with, which greatly simplifies the technical arrangement of the temperature control assembly.
A temperature control assembly according to the present invention includes a base having a top side and a bottom side opposite the top side. The substrate comprises or consists of a preferably flexible substrate material. The assembly further comprises at least one thermoelectric device, which is arranged in or at the base body, comprising a main side and a secondary side and at least one thermoelectrically active (active) element, preferably at least two thermoelectrically active elements, particularly preferably a plurality of thermoelectrically active elements, for heat transfer between the main side and the secondary side. Furthermore, the assembly comprises at least one heat-conducting element, which is arranged in the base body. In each case, a heat conducting unit is preferably provided for each thermoelectric device present. The at least one heat conducting unit in turn comprises at least one mechanically flexible heat conducting element, preferably at least two heat conducting elements, particularly preferably a plurality of heat conducting elements, and is formed for heat transfer between the assigned thermoelectric device and the top side or/and the bottom side of the base body. The heat conducting element comprises or consists of a heat conducting material. The material is preferably a metal.
For temperature control or cooling of the top side of the base body, heat can be transported from the top side of the base body to the main side of the assigned thermoelectric component via the heat conducting unit.
If the thermoelectric component is arranged completely within the base body, the heat which is further conducted from the primary side to the secondary side can be further conducted to the bottom side of the base body by means of a further heat conducting unit and can be discharged there to the surrounding region of the base body.
If at least the secondary side of the thermoelectric component is arranged directly on the underside of the base body or even outside the base body, the heat which is transferred by the at least one thermoelectric component from the primary side to the secondary side can be directly conducted out of the secondary side to the surrounding region of the secondary side and can thus be dissipated from the base body.
The thermoelectric device can be a Peltier element orIncluding peltier elements. As previously mentioned, such peltier elements can comprise a plurality of thermoelements, each element being made of a p-doped or n-doped semiconductor material, such as bismuth telluride (Bi) 2 Te 3 ) Or silicon germanium (SiGe) (not detailed in fig. 1). These thermoelements can be electrically connected to one another in a conventional manner, preferably in series, by means of electrically conductive bridges made of an electrical conductor, in particular a metal. The metal bridges can then alternately form the hot or cold side of the peltier element, in this example thus forming the primary or secondary side of the thermoelectric device. In a known manner, the peltier element can advantageously have two plates, each made of ceramic, in particular alumina ceramic, between which the thermoelectrically active element is arranged, advantageously welded.
The peltier element can advantageously have a lateral surface extension of 10mm × 10mm to 20mm × 20 mm. It goes without saying, however, that other dimensions are also conceivable in the alternative.
The exact construction or technical arrangement of the peltier element is not central to the present invention and is known to the person skilled in the art, so that a further explanation of the technical arrangement of the peltier element is dispensed with.
It goes without saying, however, that the assembly described here can have not only one thermoelectric device or one peltier element, but also two or more thermoelectric devices or peltier elements. If the temperature control assembly comprises two or more thermoelectric devices, according to the invention there is at least one heat conducting unit for each thermoelectric device.
According to a preferred embodiment of the invention, the at least one base fluid path of the temperature control assembly according to the invention is formed separate from the at least one heat conducting unit. The matrix fluid path is therefore particularly preferably arranged at a distance from the heat conducting unit in the matrix. In this way, it can be ensured that heat transfer through the heat conducting unit can take place independently and without being disturbed by heat transfer of air guided through the fluid path. This therefore results in an increase in the heat transfer efficiency, which can be achieved in assemblies remote from the top side of the base body.
According to an advantageous further development, the at least one base body fluid path opens into an upper path opening through an upper end facing away from the heat exchanger fluid path, which upper path opening is arranged on the top side of the base body. Air from the surrounding area of the top side can be introduced into the base fluid path via this path opening. This will result in an efficient cooling of the top side of the basic body. It goes without saying that when the top side of the substrate is to be heated, it is also conceivable to provide hot air via the substrate fluid path of the top side.
According to a further advantageous further development, the at least one base body fluid path opens into a lower path opening via an end facing away from the top side, which lower path opening is provided on the bottom side of the base body. Air from the at least one base fluid path can be introduced into the heat exchanger via this lower path opening in a technically simple manner. This makes it possible to use air (as described above) as a medium which can also absorb the heat provided by the heat exchanger without much technical effort.
According to a preferred embodiment, the at least one heat conducting element is directly surrounded by the matrix material. Particularly preferably, the heat conducting unit can be embedded in the matrix material. If a material with a low thermal conductivity and a low heat capacity, such as foam, is used as the matrix material, it can be ensured in this way that a large part of the heat absorbed from the top side is efficiently transferred to the assigned thermoelectric device and dissipated from the bottom side of the matrix through the latter.
According to a preferred embodiment, at least one heat conducting element thermally connects a main side of the thermoelectric device to a top side of the base body. Alternatively or additionally, the heat conducting unit can thermally connect the secondary side of the thermoelectric device to the bottom side of the base body. Depending on the position of the at least one thermoelectric device in the base body, in the case of the present embodiment, the heat conducting unit can also thermally connect the secondary side of the respective thermoelectric device to the bottom side of the base body if the thermoelectric device is arranged within the base body at a distance from the bottom side of the base body. In this way, heat can be efficiently transported from the top side to the bottom side of the base body independently of the position of the thermoelectric device in or at the base body.
The assembly advantageously comprises a heat exchanger arranged on the secondary side of the at least one thermoelectric device, through which heat exchanger air can flow for transferring heat between the thermoelectric device and the air. The heat exchanger is particularly advantageously formed for the flow of air for absorbing/delivering heat from/to the secondary side of the thermoelectric device.
At least one of the matrix fluid paths is advantageously in fluid communication with the heat exchanger fluid path. This makes it possible to dissipate the heat, which is transmitted by the heat-conducting unit via the at least one thermoelectric device to its secondary side, into the same medium which also serves to cool the top side of the seat body directly, i.e. the air which is conducted through the base fluid path and subsequently through the heat exchanger fluid path. This significantly improves the heat transfer efficiency compared to conventional assemblies.
At least one matrix fluid path is preferably realized by an air duct formed in the matrix material of the matrix. It is therefore possible to dispense with the provision of a separate duct material for the limiting air duct, since in the case of the present embodiment the matrix material (for example an airtight foam) takes over this function. This alternative is associated with significant cost advantages in the production of the component.
According to a further advantageous further development, an additional heat conducting unit for heat transfer between the at least one thermoelectric device and the air conducted through the heat exchanger fluid path is provided between the secondary side and the heat exchanger fluid path. This measure also improves the heat dissipation at the top side of the base body.
According to a further advantageous further development, the fin structure is arranged in the heat exchanger fluid path on the secondary side of the thermoelectric device or in the region of the (additional) heat conducting unit. The fin structure is configured to improve heat transfer between air directed through the heat exchanger fluid path and the at least one thermoelectric device.
According to another preferred embodiment, the assembly can include a fan in fluid communication with the heat exchanger fluid path to draw air from the heat exchanger fluid path or from the base fluid path. In this way, the intake of air from the top side of the basic body can be improved, so that the cooling effect obtained can be increased.
At least one thermoelectric device can advantageously be arranged in the base body. This design requires particularly little installation space. However, in the alternative, the thermoelectric device can also be arranged outside the substrate. Such a design is particularly easy for the worker to implement, especially in situations where, for example, maintenance of the thermoelectric device is required. It is also conceivable that, in a further development, at least one thermoelectric device is arranged within the base body and at least one further thermoelectric device is arranged outside the base body.
The at least one thermoelectric component is particularly preferably arranged in the base body at a distance from the top side or/and the bottom side of the base body. In the alternative, the thermoelectric device can be arranged on the top side or on the bottom side of the base body. The thermoelectric device can thus be arranged in or on the substrate in an application-specific manner virtually anywhere. This increases the flexibility when integrating further components, which are not part of the assembly according to the invention, into the base body.
The material of the matrix can advantageously be or can comprise a foam. Since the foam is a flexible material, it is easier in this way to integrate various components, such as thermoelectric devices and heat conducting elements, into the matrix.
Alternatively or additionally, the base body can comprise or be a support structure, which is preferably made of mechanically rigid support elements, particularly preferably of mechanically rigid wires. In this alternative, the heat-conducting elements of at least one heat-conducting unit are arranged between their supporting structures or supporting elements. In this way, a high mechanical stability of the substrate can be ensured even if the heating element is formed in a mechanically flexible manner. Advantageously, the material of the support element is plastic.
An embodiment in which the lateral extent of the upper element section along the primary side of the thermoelectric device is greater than the lateral extent of the lower element section along the secondary side of the thermoelectric device has proved to be particularly advantageous. In this way, a larger lateral extension of the top side of the base body can be thermally coupled to the main side of the thermoelectric component having a smaller lateral extension.
According to a further preferred embodiment, the heat conducting unit can taper from the top side of the base body towards the at least one thermoelectric device. Thus, the larger lateral extension of the top side of the base body can be coupled to the main side of the thermoelectric device having the smaller lateral extension in a thermally efficient manner.
According to a preferred embodiment, the at least one heat conducting unit extends over the entire top side of the base body at least through the upper end portion. In this way it is prevented that the desired temperature control cannot catch individual areas of the top side.
According to a further preferred embodiment, the at least one heat conducting element of the at least one heat conducting unit is at least partially formed by wires or/and threads, respectively, made of metal. The thread or wire can particularly preferably be at least partially wound together or/and can be partially fanned out in a non-wound manner.
According to a further preferred embodiment, the threads or filaments of the at least one heat conducting element of the at least one heat conducting unit can at least partially form a woven fabric. In this case, the threads or filaments form the warp and weft of such woven fabrics. The entire at least one heat-conducting element can preferably be formed as a woven fabric. Particularly preferably, this applies to two or more or even all heat conducting elements of the at least one heat conducting unit. In all alternatives, the formation as a woven fabric will provide a particularly uniform temperature control of the entire top side of the base body.
According to an advantageous further development, the woven fabric comprises, in a longitudinal section of the assembly, an upper element section which is arranged on the top side of the base body and is connected to a lower element section of the woven fabric which is arranged on the bottom side of the base body via an intermediate element section which extends through the base body.
According to an advantageous further development, the woven fabric has a U-shaped geometry in longitudinal section of the assembly, which comprises two U-shaped legs and a U-shaped base connecting the two U-shaped legs. In this further development, the first U-shaped leg comprises an upper element section, the second U-shaped leg comprises a lower element section, and the U-shaped base comprises an intermediate section. This U-shaped geometry allows a space-saving thermal connection of the main side of the thermoelectric component to the top side of the base body.
According to a further advantageous development, the woven fabric can have an H-shaped geometry in a longitudinal section of the assembly, which comprises two H-shaped legs and an H-shaped base connecting the two H-shaped legs. This H-shaped geometry connects the entire main side of the thermoelectric component to the entire top side of the base body in a simple manner via the heat conducting element. Thus, a planar thermal connection to the top side of the base body can be achieved by the upper element section. Since the intermediate element section requires only little installation space in the transverse direction (i.e. perpendicular to the heat transport direction), these regions of the base body can be used for other applications or technical components.
The wires or threads particularly preferably extend in a non-twisted manner from the main side of the thermoelectric component to the top side of the base body.
The at least one heat-conducting unit is particularly preferably arranged/embedded in the material of the base body and is directly surrounded by the base material of the base body. In this way the heat conducting element of the heat conducting unit is protected from damage or even destruction. When a material having a low thermal conductivity or/and heat capacity is selected as the matrix material, efficient heat transfer can be further ensured. The effect is that heat is transferred from the top side of the base body to the thermoelectric device via the heat-conducting element and further to the bottom side of the base body via the latter with low losses. Thereby counteracting unwanted heating of the substrate.
The cover can advantageously be arranged on the top side of the base body. In this way, the top side of the basic body can be protected against contamination, damage, etc. If the temperature control assembly is used for temperature control of a vehicle seat, the covering body can be a seat cover, in particular a leather cover or a textile cover. In this case, the cover serves to increase the sitting comfort. The cover can also replace the function of the design element.
According to an advantageous further development, the temperature control assembly has two or more thermoelectric devices, whereby for each thermoelectric device there is at least one heat conducting unit as described above. Large-area temperature control assemblies can also be subjected to effective temperature control, in particular cooling, in this way.
At least two thermoelectric devices (preferably electrically connected in parallel or series) can advantageously be electrically connected to each other. This simplifies the electrical wiring of the temperature control assembly according to the invention and the current supply of the thermoelectric device.
The at least one thermoelectric device particularly preferably comprises a peltier element or is a peltier element. Such peltier elements are commercially available in various technical designs, so that a person skilled in the art will be able to select them in an application-specific manner for the temperature control assembly according to the invention and they will be able to be integrated into the assembly without any problems.
According to an advantageous further development, an additional heat-conducting unit can be arranged between the secondary side and the heat exchanger, which additional heat-conducting unit comprises at least one additional heat-conducting element for heat transfer between the at least one thermoelectric device and the heat exchanger. In this way, the thermal coupling between the heat exchanger and the thermoelectric device can be improved. The additional heat conducting unit can be formed in the same manner as the (non-additional) heat conducting unit described above, so that the above description about the heat conducting unit also applies to the additional heat conducting unit as necessary.
For further temperature control or cooling of the top side, the temperature control assembly introduced here preferably comprises at least one base fluid path which is guided through the base and opens into the top side of the base for guiding air from the top side to the bottom side of the base or, conversely, from the bottom side to the top side of the base. In this way, the temperature of the surface can be controlled particularly effectively and cooling can be carried out in particular.
The invention also relates to a vehicle seat for a motor vehicle, comprising a seat bottom and a seat back. The vehicle seat further comprises the above-described temperature control assembly according to the invention, wherein the base body is at least part of the seat bottom or/and the seat back. The above-mentioned advantages of the assembly according to the invention are therefore also applicable to the vehicle seat according to the invention.
The above-described temperature control assembly according to the present invention can be installed not only in the seat bottom or the seat back of the vehicle seat as described above but also in the headrest (if present) of the vehicle seat.
It is also conceivable to provide the temperature control assembly according to the invention in other components of the motor vehicle. In particular, the center armrest, the inner door panel, the hand-operated steering wheel and the roof of the motor vehicle, in particular the headliner, can be used. The vehicle interior for controlling the gear lever of the motor vehicle and the dashboard (dashboard), in particular the dashboard (instrument panel), can also be equipped with a temperature control assembly according to the invention.
Furthermore, the temperature control assembly according to the invention can be provided not only in a vehicle seat, but generally in any seat, in particular for any vehicle. In all these alternatives, the arrangement of the temperature control assembly at the seat bottom, the seat back and possibly the headrest can be envisaged in a similar manner.
A use of the temperature control assembly according to the invention other than vehicle applications is also conceivable. In particular, applications of the temperature control assembly according to the invention in homes and buildings are envisaged, preferably on chairs or handles, in particular on door or window handles.
Finally, the use of the temperature control assembly according to the invention in the interior of buildings is also envisaged, for example on walls which laterally delimit the respective interior, and on ceilings which delimit the interior ceiling. The temperature control assembly can in particular be provided on or in a wallpaper covering a wall.
Further important features and advantages of the invention emerge from the dependent claims, the figures and the corresponding figure description based on the figures.
It goes without saying that the features mentioned above and those yet to be described below can be used not only in the respectively specified combination but also in other combinations or alone, without departing from the scope of the present invention.

Detailed Description
Fig. 1 shows an example of a temperature control assembly 1 according to the invention in a schematic view. It comprises a base body 4, having a top side 2 and a bottom side 3, made of a flexible base material. The top side 2 is opposite to the bottom side 3 in the heat transport direction W. The heat transport direction W extends in a direction of a normal vector of a plane (not shown in the figure) extending parallel to the top side 2 or/and the bottom side 3.
The assembly 1 further comprises a thermoelectric device 5 which is arranged at the base body 4 and has a main side 6 and a secondary side 7, and a plurality of thermoelectrically active elements (not shown) for heat transfer between the main side 6 and the secondary side 7. The primary side 6 is opposite to the secondary side in the heat transfer direction W. The main side 6 faces the bottom side 3.
The thermoelectric device 5 can be or comprise a peltier element. Such peltier elements can comprise said thermoelectrically active element, for example made of a p-doped or n-doped semiconductor material, respectively, such as bismuth telluride (Bi) 2 Te 3 ) Or silicon germanium (SiGe) (not detailed in fig. 1). These thermoelements can be electrically connected to one another in a conventional manner by means of electrically conductive conductor bridges made of electrical conductors, in particular metals. Said conductor bridges can then alternately form the hot and cold sides of the peltier element, thus forming in this example the primary side 6 or the secondary side 7 of the thermoelectric device 5.
In a known manner, the peltier element can advantageously have two plates made of ceramic, in particular alumina ceramic, between which the thermoelectrically active element and the conductor bridge can be arranged and advantageously welded.
The peltier element can particularly advantageously have a transverse extent of 10mm × 10mm to 20mm × 20 mm. It goes without saying, however, that other dimensions are also conceivable.
The detailed technical design of the peltier elements which can be used in the present invention is not at the heart of the present invention and is known to the person skilled in the art, so that a further explanation of the technical arrangement of such peltier elements is dispensed with.
It goes without saying that the assembly described here can have not only a single thermoelectric device 5 or a single peltier element, but also two thermoelectric devices 5 or peltier elements.
Furthermore, the heat-conducting unit 9 of the assembly 1 is arranged in the base body 4. If the assembly 1 comprises two or more thermoelectric devices 5, at least one separate heat conducting unit 9 is provided for each thermoelectric device 5. The heat conducting unit 9 comprises at least one mechanically flexible heat conducting element 10, which is configured for heat transfer between the thermoelectric device 5 and the top side 2 or/and the bottom side 3 of the base body 4. Thus, the heat transfer is substantially performed in the heat transfer direction W. Thus, the heat conducting element 10 can also extend at an angle to the heat transport direction W.
The heat-conducting unit 9 is arranged in or embedded in the matrix material of the matrix 4 and is therefore directly surrounded by the matrix material. The material of the heat conducting element 10 is advantageously a heat conducting material. For this reason, metals (e.g. copper) are preferably possible. The material of the base body 4 can preferably be foam. In the example of fig. 1, the assembly 1 further comprises a plurality of base fluid paths 20, which are respectively guided through the base 4 and open into the top side 2 of the base 4 for guiding air L from the top side 2 of the base 4 to its bottom side 3 or in the opposite direction from the bottom side 3 to the top side 2.
As shown in fig. 1, the base fluid path 20 is formed spatially separated from the heat conducting unit 9 and is arranged in the base 4 at a distance from the heat conducting element 10 of the heat conducting unit 9. The assembly 1 further comprises a heat exchanger 21, which is partially arranged on the secondary side 7 of the thermoelectric device 5, for transferring heat between the thermoelectric device 5 and the air L. The heat exchanger 21 has a heat exchanger fluid path 22 through which the air L can flow.
Furthermore, a matrix fluid path 20 can be provided in the matrix 4 in order to be thermally separated from the heat conducting elements 10 of the heat conducting unit 9 by means of a thermal insulation. The foam can thus be formed by means of the material of the matrix. In the alternative, in particular when the material of the base body 4 is not foam, an insulating body can be formed by an insulating layer (not shown in the figures), which is preferably made of foam or another material, in particular with a low thermal conductivity, as the base body material.
According to fig. 1, all of the base fluid paths 20 are in fluid communication with the heat exchanger fluid path 22. In each case, the base fluid path 20 can be realized by an air duct 28 formed in the material of the base 4. In this case, the air conduit 28 or the matrix fluid path 20 is directly limited by the material of the matrix 4 (e.g. the foam). The base fluid paths 20 each open via an upper end 23 facing away from the heat exchanger fluid paths 20 into an upper path opening 24 which is provided on the top side 2 of the base body 4 and via which air L from a surrounding area 25 of the top side 2 can be introduced or sucked into the respective base fluid path 20. The base fluid paths 20 open out through a common lower end 26 facing away from the top side 2 into a lower path opening 27 which is provided on the bottom side 3 of the base 4 and via which air L can be conveyed from the base fluid paths 20 to the respective heat exchanger fluid paths 22. As previously mentioned, air may also be delivered in the opposite direction from the lower pathway opening 27 into the upper pathway opening 24.
Furthermore, as can be seen from fig. 1, an additional heat conducting unit 29 for heat transfer between the thermoelectric device 5 and the air L guided through the heat exchanger fluid path 22 can be provided between the secondary side 7 of the thermoelectric device 5 and the heat exchanger fluid path 22 of the heat exchanger 21. The additional heat-conducting unit 29 can be constructed in exactly the same way as the heat-conducting unit 9 in the base body 4 and can therefore comprise a plurality of heat-conducting elements 30. Therefore, the above explanations relating to the heat conducting unit 9 also apply to the additional heat conducting unit 29. Such additional heat conducting elements 29 can optionally be provided for each heat conducting element 9 present in the base body 4.
Furthermore, a fin structure (not shown) can be provided in the heat exchanger fluid path 22 in the region of the secondary side 7 of the thermoelectric device 5 or the additional heat conducting unit 29 for improving the heat transfer between the air L guided through the heat exchanger fluid path 22 and the thermoelectric device 5.
In an example scenario, the assembly 1 further comprises a fan 31 in fluid communication with the heat exchanger fluid path 22 to draw air L from the heat exchanger fluid path 22 or from the base fluid path 20. The fan 31 can advantageously be arranged downstream of the heat exchanger 21.
The cover body 8 can advantageously be arranged on the top side 2 of the base body 4. The top side 2 of the basic body 4 can in this way be protected against soiling, damage and the like. The cover 8 can comprise one or more cover layers. For example, a two-layer arrangement comprising a leather layer on the top side and a foam layer on the bottom side is conceivable.
Fig. 2a to 2k show various configuration options of the heat conducting unit 9 with the heat conducting element 10.
For this purpose, fig. 2a to 2k show the base body 4 comprising the thermoelectric component 5 in a substantially schematic and highly simplified illustration and in a longitudinal section along the heat transport direction W. The various alternatives can be combined with each other as far as this is reasonable. If two or more heat conducting units 9 are provided (not shown in the figures), they can be formed identically or differently, according to different alternatives.
In the example of fig. 2a to 2e, the heat conducting element 10 is formed by a wire 12 or wire made of metal.
In the example of fig. 2a, the single heat conducting unit 9 comprises only a single heat conducting element 10 consisting of wires or threads, which are wound together in an exemplary manner. For this purpose, the heat-conducting element 10 has a greater lateral extension along the top side 2 than the same heat-conducting element 10 along the main side 6 of the thermoelectric device 5. In this way, a larger lateral extension of the top side 2 of the base body 4 can be thermally coupled to the main side 6 of the thermoelectric device 5 having a smaller lateral extension.
In the example of fig. 2b, the heat conducting unit 9 comprises not only a single heat conducting element 10 in an exemplary manner, but also two heat conducting elements 10 arranged adjacent to each other, wherein each heat conducting element 10 can be formed in the manner described above on the basis of fig. 2 a. The two heat-conducting elements 10 can be arranged at a distance from one another. It goes without saying that in a further development of this example, the heat-conducting unit 9 can also have three or more such heat-conducting elements 10.
In the example of fig. 2a and 2b, the two heat-conducting elements 10 extend substantially in the heat transport direction W, so that the shortest possible connection is achieved between the top side 2 and the bottom side 3 of the basic body 4.
Fig. 2c shows an alternative to the example of fig. 2a, in which (only) the heat conducting element 10 extends from the thermoelectric device 5 to the top side 2 at an angle α, preferably an acute angle, with respect to the heat transport direction W. This angled arrangement makes it possible to thermally connect the thermoelectric device 5 to generally any lateral region of the top side 2 via the heat conducting unit 9.
It goes without saying that a combination of the examples of fig. 2c and 2b is also conceivable.
In the example of fig. 2d, the heat conducting unit 9 again comprises only one heat conducting element 10. In the example of fig. 2d, the heat conducting element 10 is divided into a first element segment 11a and a second element segment 11b with respect to the heat transport direction W. The two element segments 11a, 11b merge into one another in the heat transport direction W. The first element section 11a faces the main side 6 of the thermoelectric element 5. The second element section 11b faces the top side 2 of the basic body 4. In the first element segment 11a, the wires or threads are wound together. In the second element segment 11b the wires or lines 12 are not twisted together but are fanned out towards the top side 2 in a non-twisted manner. Since the heat-conducting element 10 is subdivided into the second element segment 11b of the wire 12 or line, which is fanned out, and the first element segment 11a, which is wound together, the heat-conducting element 10 tapers from the top side 2 to the bottom side 3. The larger lateral extension of the top side 2 of the base body 4 can in this way be coupled in a thermally efficient manner to the main side 6 of the thermoelectric component 5 having the smaller lateral extension. In the example of fig. 2d (and in the examples of fig. 2a to 2 c), the lateral extension of the heat conducting element 10 along the top side 2 is therefore also larger than the lateral extension of the same heat conducting element 10 along the main side 6 of the thermoelectric device 5.
Fig. 2e shows an alternative to the example of fig. 2 d. Unlike the example of fig. 2d, the heat-conducting element 10 in the example of fig. 2e is not formed by fanned-out threads or filaments 12 that are not wound together, but by a woven fabric 13 of threads or filaments 12. The threads or filaments 12 thus at least partially form the warp and weft threads (not shown in fig. 2 e) of the woven fabric 13.
In the example of fig. 2e, the heat conducting unit 9 thus comprises a first element section 11a, in which the heat conducting element 10 is formed as a wound wire or/and thread 12, and a second element section 11b, in which the heat conducting element 10 is formed as a woven fabric 13. The threads or filaments 12 wound in the first element section 11a thus merge towards the top side 2 to the warp and weft threads of the woven fabric 13. Such a woven fabric 13 arranged in the region of the top side 2 allows a particularly uniform temperature control of the top side 2. In the alternative, the woven fabric 13 and its warp and weft threads can also be formed separately from the heat-conducting element 10 and can be connected thereto for heat conduction. For this purpose, suitable material bonds, in particular adhesive bonds or welded bonds, can be used.
The examples of fig. 2c to 2e can also be combined with the example of fig. 2b, i.e. a heat conducting unit 9 can also be provided, which is assigned to the respective thermoelectric device 5, in the examples of fig. 2c to 2e respectively comprises two or more heat conducting elements 10.
Fig. 2f to 2i show further examples in which the heat-conducting element 10 is formed by a woven fabric 13 made of threads or filaments 12, forming warp threads or weft threads (not shown) of the woven fabric 13.
In the example of fig. 2f, the woven fabric 13 comprises, in the shown longitudinal section of the assembly 1 in the heat transport direction W, an upper element section 14o arranged on the top side 2 of the base body 4, which is connected to a lower element section 14u of the woven fabric 13 arranged on the bottom side 3 of the base body 4 via an intermediate element section 14m extending through the base body 4.
As shown in fig. 2f, the upper element section 14o extends transversely (i.e. perpendicular to the heat transport direction W) on the top side 2 of the basic body 4. The lower element section 14u therefore extends laterally beyond the main side 6 of the thermoelectric device 5. The intermediate element section 14m connects the upper element section 14o to the lower element section 14u and extends for this purpose in the heat transport direction W. Thus, in the longitudinal section shown, woven fabric 13 has an H-shaped geometry, comprising two H-shaped legs 16a, 16b and an H-shaped base 16c connecting the two H-shaped legs. The upper element section 14o forms a first H-shaped leg 16a and the lower element section 14u forms a second H-shaped leg 16 b. The intermediate element section 14m forms an H-shaped base 16 c.
The illustrated H-shaped geometry allows an effective connection of the entire main side 6 of the thermoelectric device 5 to the entire top side 2 of the base body 4 via the heat conducting element 9. A planar thermal connection to the top side 2 of the base body 4 is thus possible via the upper element section 14 o. Since the intermediate element section 14m requires only little installation space in the transverse direction (i.e. perpendicular to the heat transport direction W), these regions of the basic body 4 can be used for other applications or technical components, in particular the basic body fluid path 20 shown in fig. 1.
Fig. 2g shows an alternative to the example of fig. 2 f. In the example of fig. 2g, the woven fabric 13 does not have an H-shaped geometry in the shown longitudinal section as in the example of fig. 2f, but a U-shaped geometry. This means that the woven fabric 13 has two U-shaped legs 15a, 15b and a U-shaped base 15c connecting the two U-shaped legs 15a, 15b, as shown. Similar to the H-shaped geometry of fig. 2, the first U-shaped leg 15a in the example of fig. 2g forms the upper element section 14o and the second U-shaped leg 15b forms the lower element section 14U. The U-shaped base 15c forms the intermediate element section 14 m. The U-shaped geometry also allows a space-saving thermal connection of the main side 6 with the top side 2, similar to the example of fig. 2 f.
Fig. 2h shows a further alternative to the examples of fig. 2f and 2 g. In the example of fig. 2h, the heat-conducting elements 10 of the heat-conducting unit 9 are also formed by a woven fabric 13, wherein the threads or wires 12 of the heat-conducting elements 10 form the warp and weft of the woven fabric.
As shown in fig. 2h, the upper element section 14o of the woven fabric 13 extends only partially on the top side 2 of the base body 4. The lower element section 14u also extends only partially on the main side 6 of the thermoelectric element 5. With respect to the transverse direction LR extending perpendicular to the heat transport direction W, the upper element sections 14o and the lower element sections 14u of the woven fabric 13 of threads or wires 12 are arranged on mutually opposite ends 37a, 37b of the top side 2 or the bottom side 3, respectively. The intermediate element section 14m is arranged at an obtuse angle β to the upper element section 14o and the lower element section 14 u. By the alternative shown in fig. 2h, the lateral portions of the top side 2 and the bottom side 3 which are opposite to each other with respect to the lateral direction LR can be connected to each other in a thermally efficient manner.
Fig. 2i shows a simplified alternative to the example according to fig. 2f to 2 h. In the example of fig. 2i, the heat-conducting element 10 of the heat-conducting unit 9 further comprises a woven fabric 13 made of warp and weft threads, which are formed by the threads or wires 12 of the heat-conducting element 10, respectively. In the example of fig. 2i, in contrast to the examples of fig. 2f to 2h, the thermoelectric component 5 is arranged in the region of the top side 2 of the base body within the base body 4. This provides a simplified arrangement of the woven fabric 13, since the intermediate element sections 14m and the lower element sections 14u can be discarded.
In the example of fig. 2i, the woven fabric 13 is provided only in the region of the top side 2 and extends in the transverse direction LR over the entire top side 2. With its woven fabric bottom 13u, the heat-conducting element 10 or the woven fabric 13 contacts the main side 6 of the thermoelectric device 5 in the region of the lateral contact section 13 k.
Fig. 2j and 2k show two further design alternatives of the heat-conducting unit 9, in which case the heat-conducting element 10 has in each case a thread or wire 12 which is arranged in a non-twisted manner and at a distance from one another. In both examples, the wires extend from a main side 6 of the thermoelectric component 5, which is arranged outside the base body 4 on the bottom side 3 of the base body, through the base body 4 to the top side 2 of the base body 4.
In the example of fig. 2j, the individual wires or filaments 12 extend substantially in the heat transport direction W. In contrast, the heat conducting unit 9 or the heat conducting element 9 formed by the line 12 tapers in the illustrated longitudinal section from the top side 2 of the base body 4 to the main side 6 of the thermoelectric device 5 or the bottom side 3 of the base body 4, respectively (in the example of fig. 2j and 2k, the bottom side 3 and the main side 6 coincide). As a result, in the example of fig. 2k, a larger lateral area of the top side 2 of the base body 4 is thermally connected to the main side 6 of the thermoelectric device 5 via the heat conducting unit 9 than in the example of fig. 2 j.
In both alternatives, therefore in the example of fig. 2j and in the example of fig. 2k, a support structure 18 made of metal wires 19 is provided in the base body 4 in addition to the wires 12. Unlike the wires 12 of the heat-conducting unit 9, these metal wires 19 are not used for heat transfer, but for mechanical reinforcement of the base body 4. For this purpose, the metal wires 19 of the support structure 18 form a so-called spacer fabric. The support structure 18 advantageously extends transversely in the heat transport direction W and also over the entire substrate 4.
Based on the general schematic diagrams of fig. 3a to 3d, various alternatives of the example of fig. 1 will be described below, which differ from each other in particular with regard to the preferred position of the thermoelectric device 5 in or at the substrate 4.
The arrangements of fig. 3a to 3b described below can be combined with the arrangements of fig. 2a to 2k, as long as this is reasonable.
In the example of fig. 3a, the thermoelectric component 5 is arranged outside the base body 4 and is arranged adjacent to the base side 3 of the base body with its main side 6. The thermoelectric component 5 is thus arranged on the bottom side 3 of the base body in a space-free manner by means of its main side 6. In other words, the main side 6 and the underside 3 coincide in fig. 3 a.
An additional heat conducting unit 29, which has been described with reference to fig. 1, comprising an additional heat conducting element 30, is arranged between the secondary side 7 of the thermoelectric device 5 and the heat exchanger fluid path 22 of the heat exchanger 21. The additional heat conducting unit 29 and the thermoelectric device 5 are arranged outside the base body 4 at a distance from the base body 4.
The alternative of fig. 3b differs from the example of fig. 3a in that the thermoelectric device 5 is arranged in the base body 4. In the example of fig. 3b, the bottom side 3 of the base body 4 and the secondary side 7 of the thermoelectric element 5 coincide. In the example of fig. 3b, an additional heat conducting unit 29 comprising an additional heat conducting element 30 adjoins the bottom side 3 of the base body 4 and thus also the secondary side 7 of the thermoelectric device. In the example of fig. 3b as well as in the example of fig. 3a, the additional heat conducting unit 29 is also arranged outside the base body 4.
The alternative shown in fig. 3c differs from the example of fig. 3b in that the thermoelectric device 5 is arranged at a distance from the top side 2 as well as the bottom side 3 within the base body 4. In the example of fig. 3c, the additional heat conducting unit 29 shown in fig. 3a and 3b is also not required. In contrast, in the example of fig. 3c, the heat conducting unit 9 comprising two heat conducting elements 10 is formed such that one of the two heat conducting elements 10 thermally connects the primary side 6 of the thermoelectric device 5 to the top side 2 of the base body 4 and the other heat conducting element 10 thermally connects the secondary side 7 of the thermoelectric device 5 to the bottom side 3 of the base body 4. In the example of fig. 3c, the heat exchanger 21 with the heat transfer fluid path 22 adjoins the bottom side 3 of the base body 4, so that the secondary side 7 of the thermoelectric device 5 is thermally connected to the heat exchanger 21 via the heat conducting unit 9.
In the example of fig. 3d, the thermoelectric component 5 is likewise arranged in the base body 4, but in contrast to the example of fig. 3c adjoins the top side 2 of the base body 4. In the example of fig. 3d, the main side 6 of the thermoelectric element 5 and the top side 2 of the base body 4 thus coincide.
In the example of fig. 3d, a heat conducting unit 9 comprising a heat conducting element 10 connects the secondary side 7 of the thermoelectric device 5 to the bottom side 3 of the base body 4. In the example of fig. 3d, a heat exchanger 21 with a heat exchanger fluid path 22 (similar to the example of fig. 3 c) also adjoins the bottom side 3 of the base body 4, so that the secondary side 7 of the thermoelectric device 5 is thermally connected to the heat exchanger 22 via the heat conducting unit 9. In the example of fig. 3d, the heat conducting unit 9 connects the secondary side 7 of the thermoelectric device 5 to the bottom side 3 of the base body 4 and thus also to the heat exchanger 21.
In the example of fig. 3c, the heat conducting unit 9 connects the top side 2 of the base body 4 to the primary side 6 of the thermoelectric device 5 and the secondary side 7 of the thermoelectric device 5 to the bottom side 3 of the base body 4, and thus also to the heat exchanger 21. In the example of fig. 3b, a heat conducting unit 9 connects the top side 2 of the base body 4 to the main side 6 of the thermoelectric device 5. In the example of fig. 3a, the heat conducting unit 9 connects the top side 2 of the base body 4 to the bottom side 3 of the base body 4 and thus also to the main side 6 of the thermoelectric device 5.
