Description

The invention relates to a thermoelectric conversion device and a vehicle.

The thermoelectric effect, also known as the Seebeck effect, is a physical solid-state effect that occurs when there is a temperature difference between two contact points of different electrical conductors in a circuit. An electrical voltage is generated between the two contact points. The thermoelectric effect converts thermal energy into electrical energy without going through a thermodynamic cycle. This results in the advantage that no moving parts are necessary for energy conversion by a thermoelectric conversion device. The thermoelectric conversion devices include thermoelectric generators, which convert thermal energy into electrical energy. These are used as stationary energy converter systems that use a temperature difference between a cold and a warm side of the thermoelectric generator to convert thermal energy into electrical energy. Series applications of thermoelectric generators are known, for example, from space travel (for example in the Mars Rover Curiosity, NASA JPL).

The reverse process is known as the Peltier effect and describes the formation of a temperature difference due to a voltage difference in different electrical conductors. The Peltier effect is used in so-called Peltier elements, for example to enable cooling, heating or thermal conditioning of components that are connected to the Peltier element. Since the thermoelectric conversion devices are scalable in terms of their size and conversion area used, specific systems can be designed in various application areas (applications in the mW to kW range) depending on the application.

With regard to a motor vehicle, thermoelectric conversion devices are conceivable for thermal energy recovery from hot exhaust gases, or for thermal preconditioning of electrical energy stores at cold temperatures.

A thermoelectric conversion device usually comprises a p- and an n-doped semiconductor forming a pair of thermoelectric legs which are electrically connected to each other. The thermoelectric materials can also be doped along a temperature gradient to increase efficiency so that the thermopower of the thermoelectric conversion device can be maximized. Since the thermoelectric power of the thermoelectric conversion device is typically in µV/K, a corresponding number of units of leg pairs must be connected in series in order to be able to make the system usable.

A thermoelectric conversion device is disclosed in US Pat DE 10 2018 130 761 A1 described. The thermoelectric conversion device has a first thermal contacting element and a second thermal contacting element opposite the first thermal contacting element and facing the first contacting element, each directly adjoining at least one common element arrangement of thermoelectric elements. The respective contacting element has a base body and a plurality of convex structural bodies which are connected to the base body and protrude from the base body, the convex structural bodies being arranged at a distance from one another, so that between two of the structural bodies there is a respective receiving area and each of the convex structural bodies one of the thermal Contacting elements engages in a respective one of the receiving areas of the corresponding other contacting element. The thermoelectric element assembly is arranged between the convex structural bodies.

The DE 10 2007 063 168 A1 describes a thermoelectric module and a thermoelectric generator. The thermoelectric module has electrical conducting elements arranged in a first layer, with electrical conducting elements arranged in a second layer spaced apart from the first layer, with a plurality of thermoelectric elements arranged between the first layer and the second layer. The thermoelectric module has at least one insulating layer, by means of which the electrical conducting elements arranged in the first layer can be electrically insulated relative to a heat source or the electrical conducting elements arranged in the second layer can be electrically insulated relative to a heat sink.

The EP 2 630 670 B1 discloses a thermoelectric device. The thermoelectric device includes at least one p-layer coupled with at least one n-layer to create a pn junction; and an insulating layer partially interposed between the p-layer and the n-layer. It is provided that the p-layer has a plurality of carbon nanoparticles arranged in a polymer matrix and the n-layer has a plurality of n-doped carbon nanoparticles that are arranged in a polymer matrix.

Prior art thermoelectric conversion devices have complex geometry to achieve higher efficiency. However, this also increases production costs.

It is an object of the invention to provide a thermoelectric conversion device that is inexpensive to manufacture.

According to the invention, this object is achieved by a thermoelectric conversion device and a vehicle. Advantageous embodiments of the invention are the subject of the dependent patent claims and the description.

A first aspect of the invention relates to a thermoelectric conversion device. The thermoelectric conversion device includes a first insulating layer and a second insulating layer which are arranged at an interface with each other. In other words, the first insulating layer and the second insulating layer are connected to each other at the interface. Provision can be made for the first insulating layer and the second insulating layer to be respective layers of a combined insulating layer which is intended for separating two different heating areas in order to thermally insulate the two heating areas from one another. The first insulating layer and the second insulating layer can be glued to one another at the interface, for example. The first insulating layer has first areas of material at the interface and the second insulating layer has second areas of material at the interface. In other words, the insulating layers have the respective material surfaces at their boundary surfaces. The material surfaces can lie flat against the boundary surface and can be regions of a layer of the respective insulating layer that are arranged parallel to the boundary surface and are spatially separated from one another.

Provision is made for the first material surfaces and the second material surfaces to be arranged in an alternating thermoelectric pattern along a parallel direction aligned parallel to the interface, with directly adjacent material surfaces of the thermoelectric pattern making contact at a respective common contacting surface. In other words, a thermoelectric pattern is formed by the first material surfaces and the second material surfaces, which is arranged at the interface and extends along the parallel direction of the interface. The first and the second material surfaces are arranged in an alternating manner along the parallel surface. The first areas of material may comprise a material that has a different thermal sensitivity than a material of the second areas of material.

In other words, the first material surfaces are arranged at a distance from one another along the parallel direction. Areas of the first insulating layer which do not have any of the first material surfaces can be arranged between them. The second material surfaces are also arranged spaced apart from one another along the parallel direction. Areas of the second insulating layer which do not have any of the second material areas can be arranged between them. Material surfaces and spaces can thus alternate along the parallel direction in the insulating layers. In the parallel direction, the first material surfaces can be arranged offset to the second material surfaces, wherein a respective space between two second material surfaces can be arranged opposite the respective first material surface and a respective space between two first material surfaces can be arranged opposite the respective second material surface. The material surfaces can, for example, be thin strips which extend on the insulating layers.

Directly adjacent material surfaces of the thermoelectric pattern make contact at respective common contacting surfaces. In other words, adjacent material surfaces are electrically conductively connected to one another at contacting surfaces. A first material surface can have, for example, the common contacting surfaces with the adjacent second material surfaces. The first and the second material surfaces are thus connected in series along the parallel direction via the contacting surfaces as a thermopile or thermochain.

The advantage resulting from the invention is that the material surfaces can be applied to the respective insulating layers in a simple manner, as a result of which a thermoelectric conversion device that can be implemented cost-effectively can be provided.

A development of the invention provides that at least one of the insulating layers has respective thermal insulating elements between its respective material surfaces, which have a lower thermal conductivity than the respective insulating layer. In other words, thermal insulating elements are arranged in at least one of the insulating layers. The thermal insulating elements have a lower thermal conductivity than the insulating layer. The thermal insulating elements are arranged between the respective material surfaces of the respective insulating layer. It can be provided that the first material surfaces and the second material surfaces are arranged spaced apart from one another in the respective insulating layer, it being possible for the respective insulating elements to be arranged in a region between the material surfaces. The further development results in the advantage that the areas arranged between the material surfaces of the respective insulating layer have a lower thermal conductivity than the areas of the material surfaces. This results in the advantage that a flow of heat through the respective insulating layer to or from the interface is primarily conducted through the respective material surfaces. Thereby, an efficiency of the thermoelectric conversion device can be increased.

A development of the invention provides that the thermal insulating elements are designed as gas inclusions in the respective insulating layer. In other words, gas inclusions are arranged in the respective insulating layer between the material surfaces. This results in the advantage that no material has to be provided to provide the insulating elements.

A development of the invention provides that the material surfaces include metals. In other words, the material surfaces have metals or consist of metals. This results in the advantage that the material surfaces comprise a material that is easy to apply.

A development of the invention provides that the material surfaces have doped semiconductors. In other words, it is provided that the material surfaces are made of or have doped semiconductors. This results in the advantage that higher efficiency can be achieved than with metals.

A further development of the invention provides that the material surfaces are inserted into the insulating layers as material inserts. In other words, it is provided that the material surfaces are produced as material inserts, which are arranged in respective depressions or trenches in the insulating layers.

A development of the invention provides that the material surfaces are printed. In other words, it is provided that the material surfaces are applied to the respective insulating layers by means of a material printing process. This enables cost-effective application of the material surfaces.

A development of the invention provides that the material surfaces are applied to the insulating layers by a vapor deposition process. Provision can be made, for example, for a mask to be placed on the respective insulating layers in order to cover regions of the insulating layers that are not to be coated. The material surfaces were then formed by the vapor deposition of the respective materials in the non-covered areas of the insulating layers.

A development of the invention provides that the thermoelectric conversion device has monitoring and/or power electronics that are set up to regulate a voltage at connection elements of the thermoelectric conversion device. In other words, the thermoelectric conversion device comprises electronic components which enable the voltage generated and/or the heat converted to be monitored and/or regulated. The power electronics are set up to set a desired voltage. This results in the advantage that the electronics required for operation can be provided in the conversion device itself.

Provision can be made, for example, for sockets to be provided for the monitoring and/or power electronics during the additive manufacturing process, into which sockets the electronic components are subsequently inserted. The electronic components can include, for example, voltage converters, sensors and/or microcontrollers. The monitoring/power electronics can be set up to exchange data for operation and diagnosis with an energy management system of the vehicle via a data bus (e.g. LIN, CAN...).

A second aspect of the invention relates to a vehicle having a thermoelectric conversion device. In other words, the vehicle in which the thermoelectric conversion device is mounted is provided. This results in the advantage that the thermoelectric conversion device can be used to utilize waste heat or to heat components of the vehicle. Provision can be made, for example, for the thermoelectric conversion device to be arranged on an internal combustion engine of the vehicle and to convert the heat given off by the engine into electrical energy.

A development of the invention provides that the thermoelectric conversion device is arranged on an electrical component of the vehicle. In other words, the thermoelectric conversion device is in direct contact with the electrical component of the vehicle. This results in the advantage that waste heat from the electrical component can be converted into electrical energy. It can be provided, for example hen that a processor of the vehicle is positively connected to a surface of the thermoelectric conversion device, so that the heat of the processor diffuses into the thermoelectric conversion device and can be used for energy conversion. The electrical component can also be used for active cooling of the component when the thermoelectric conversion device is used as a Peltier element.

A development of the invention provides that the thermoelectric conversion device is arranged in a form-fitting manner on an inner surface of the vehicle interior or on an outer surface of the vehicle. In other words, the thermoelectric conversion device is arranged on a surface that defines the vehicle interior or on a surface that is on an outside of the vehicle. For example, the thermoelectric conversion device may be arranged on an underside of the vehicle.

A development of the invention provides that the thermoelectric conversion device is arranged on an electrical energy store of the vehicle. In other words, the thermoelectric conversion device has a common area with the electrical energy store. This results in the advantage that the thermoelectric conversion device can be used for heating or cooling the electrical energy store. It can be provided, for example, that the thermoelectric conversion device can be used to heat an electrical energy storage device designed as an accumulator, so that the temperature of the electrical energy storage device can be adjusted to an operating temperature.

1 shows a schematic representation of a thermoelectric conversion device 1. The thermoelectric conversion device 1 can be provided to be arranged in an area between two components with different temperatures T1, T2 to a temperature difference between the temperature T1 and the temperature T2 for generating electrical energy use. The thermoelectric conversion device 1 may have a first insulating layer 2 and a second insulating layer 3 . The first insulating layer 2 and the second insulating layer 3 can be intended to be glued together at a common interface 4 . The first insulating layer 2 can have first material areas 5, which can have a metal or a doped semiconductor. The first material surfaces 5 can, for example, be vapour-deposited on the first insulating layer 2, printed or inserted as inserts in depressions in the first insulating layer 2. The first material surfaces 5 can be separated from one another by respective intermediate regions. The first material surfaces 5 can be strips, which can be arranged in a pattern along a direction running parallel to the interface 4 . The second insulating layer 3 can have second material surfaces 6, which can have different materials than the first material surfaces 5. The second material surfaces 6 can like the first material surfaces 5, can be spaced apart by distances. The second material surfaces 6 can be arranged offset in relation to the first material surfaces 5 in the parallel direction 7 , so that one of the second material surfaces 6 can be arranged opposite a gap 13 of the first insulating layer 2 between two of the first material surfaces 5 . In order to be able to tap the voltage, the thermoelectric conversion device 1 can have a first electrical connection and a second electrical connection. The first electrical connection can contact one of the first material surfaces 5 and the second electrical connection can contact one of the second material surfaces 6 . An advantage of the thermoelectric conversion device 1 is that the material surfaces are applied to the respective insulating layers. This can avoid providing complex structures, which is common in thermoelectric conversion devices 1 according to the prior art.

The figure shows the side view of the two insulating layers. The first insulating layer 2 and the second insulating layer 3 each contain strip-shaped metal inserts or inserts with materials with p- and n-doping in the z-direction. For example, these inserts can be inserted mechanically or produced using a printing process comparable to inkjet printing. The electrical contact is preferably contained in an insulating layer, outlined by the electrical connections.

2 shows a further schematic representation of a thermoelectric conversion device 1. The thermoelectric conversion device 1 can in 1 shown thermoelectric conversion device 1 after arranging the two insulating layers at their interface 4. The material surfaces can be arranged offset to one another, so that an alternating pattern is formed along the parallel direction 7, in which the first material surfaces 5 and the second material surfaces 6 alternate. The material surfaces of one of the insulating layers 2, 3 can rest against the intermediate area of the opposite insulating layers 2, 3. The material surfaces can overlap at the interface 4 and form contact surfaces 8 with the adjacent material surfaces of the other insulating layer. The material surfaces can be electrically conductively connected and connected in series via the contact surfaces 8 .

The figure shows the side view of the insulating layers joined together in a form-fitting manner. The electrical contacting of the metal inserts or inserts with materials with P and N doping can also be seen here. There is either a metal layer between the two materials with P and N doping or the direct connection of the metal inlays or inlays with materials with P and N doping is sufficient.

3 shows a schematic representation of a thermoelectric conversion device 1 with insulating elements 11. It can be provided that respective thermal insulating elements 11 are arranged in the gaps 13 between material surfaces, which can have a lower thermal conductivity than the insulating layer itself. The thermal insulating elements 11 can be gas insulators, for example. As a result, a flow of heat, which can run through the insulating layers, is conducted to the material surfaces of the respective insulating layer. This results in the advantage that a larger temperature gradient can be provided between the different material surfaces.

The figure shows the side view of the form-fitting assembled insulating layers with an additional air or gas insulation. The purpose of this is to increase the thermal insulation or to direct the temperature gradient to the thermoelectric system. The electrical contacting of the metal inserts or inserts with materials with P and N doping can also be seen here.

4 shows a schematic representation of the insulating layers. Areas of the insulating layers which form the interface 4 in an assembled state of the thermoelectric conversion device 1 are shown. The layers of material can be square or oblong.

The figure shows the top view of the insides of the two insulating layers 2, 3. This shows the strip-like structure of the metal inserts or inserts with materials with p- and n-doping. The additional air or Gas insulation is not shown herein.

5 shows a schematic representation of a connecting layer for gluing the insulating layers. A wetting of the two insulating layers with adhesive to form a connecting layer is shown. A functional thermoelectric system is created by the form-fitting assembly with the corresponding offset of the metal inserts or inserts with materials with P and N doping. Optionally, the electrical contacting surface can contain an overhang or roughness to improve the pressure and the electrical conductivity.

6 Fig. 12 is a schematic representation of a side view of the thermoelectric conversion device 1 having the bonding layer. The respective material surfaces can protrude slightly from the respective insulating layer, so that the intermediate areas between two material surfaces are lowered. The adhesive of the connecting layer can be introduced into these intermediate areas. By raising the material surfaces, contact between the first material surfaces 5 and the second material surfaces 6 can be ensured and/or improved.

The figure shows the thermoelectric conversion device 1 in a bonded state in side view. The electrical contacting of the metal inserts or inserts with materials with P and N doping can also be seen here. The thermoelectric materials are thus electrically connected in series in strips. The series connection of a sufficient number of strip-shaped elements results in a sufficiently high electrical voltage. This can be the voltage of the vehicle electrical system, i.e. 9..16 V, for example.

7 shows a schematic representation of a connection of the thermoelectric conversion device to an on-board network of a vehicle. Provision can be made for the monitoring and power electronics 14 to be integrated into the thermoelectric conversion device 1 in order to connect the thermoelectric conversion device 1 to the vehicle electrical system 15 of the vehicle 16 . For this purpose, printed, integrated sockets for microchips can be arranged in the thermoelectric conversion device 1, which can comprise a diode. The electronics can be provided for temperature monitoring or voltage monitoring, for example. Voltage converters can also be provided, or components that enable diagnosis and/or error detection. Manufacture of the thermoelectric conversion device 1 allows almost any configuration of shape and size. This results in the advantages that optimal use of space, cost-effective production, use of different heat sources and provision of integrated electronics and fault monitoring components are made possible.

8th shows a further schematic representation of a connection of the thermoelectric conversion device to an on-board network of a vehicle. Shown is a connection of the thermoelectric conversion device 1 to the vehicle electrical system 15 of the vehicle 16 via monitoring and power electronics 14, which can include a DC voltage converter.

9 shows a further schematic representation of a connection of the thermoelectric conversion device to an on-board network of a vehicle. Shown is a connection of the thermoelectric conversion device 1 to the vehicle electrical system 15 of the vehicle 16 via monitoring and power electronics 14, which can include an output stage and a switch.

The electrical coupling to the vehicle electrical system according to the figure can take place on the one hand in the case of using the Seebeck effect, i.e. by using the temperature gradient to generate electricity, by a diode or by a DC voltage converter. With the DC converter, a so-called maximum power point control can be implemented to maximize the overall efficiency. On the other hand, if the Peltier effect is used, an electrical feed into the thermoelectric system can generate heating or cooling, i.e. a temperature gradient between the two insulating layers and the adjacent rooms. This results in a simple and material- and cost-saving method for the integration of thermoelectric systems in insulating surfaces, including the electrical contacting.

Basically, there is the problem that the energy consumption in the parked vehicle leads to a discharge of the traction or on-board power supply battery and thus reduces the downtime of the vehicle or the starting of the vehicle is impaired after a long period of inactivity. Thus, additional power sources are useful to mitigate the problem. Furthermore, thermal problems are known both in the case of cooling components and in the heating of components, for example to ensure the performance of a traction storage system in the thermal limit range.

Insulating layers or insulating foils, which primarily separate two areas with different temperatures, are designed in two parts with an integrated thermoelectric system. The thermoelectric system is used either to generate electricity (Seebeck effect, use of different temperature levels) or for heating or cooling (Peltier effect, generation of different temperature levels).
