Definitions
- thermoelectric device comprising a hot side and a cold side, wherein the hot side is thermally coupled to an exhaust gas system of an internal combustion engine, a vehicle and a use of the thermoelectric device.
- Thermoelectric generators or devices and Peltier arrangements have been known for a long time, p- and n-doped semiconductors, which are heated on one side and cooled on the other side, transport electric charges through an external circuit, so that electrical work can be performed on a load in the circuit.
- the efficiency thereby achieved for the conversion of heat into electrical energy is thermodynamically limited by the Carnot efficiency.
- efficiencies up to approximately 6% have been achieved.
- Peltier arrangement works as a heat pump and is there- fore suitable for cooling equipment parts, vehicles or buildings. Heating by means of the Peltier principal is also more favorable than conventional heating, because more heat is always transported than corresponds to the energy equivalent supplied.
- thermoelectric generators are used in space probes for the generation of direct currents, for the cathodic corrosion protection of pipelines, for the energy supply of light and radio buoys, and for the operation of radios and televisions.
- the advantages of thermoelectric generators reside in their extreme reliability. They operate irrespective of atmospheric conditions such as relative humidity; no material transport susceptible to interference takes place, rather only charge transport.
- the thermoelectric device typically comprises p-and n-type pieces, which are connected electrically in series and thermally in parallel.
- a conventional structure comprises two ceramic plates, between which the individual pieces are fitted alternately. Two pieces are in each case contacted electrically conductively via the end faces. Besides the electrically conductive contacting, various further layers are normally also provided on the actual material, which serve as protective layers or as solder layers. The electrical contact between two pieces is established via a metal bridge.
- a thermoelectric material inside the thermoelectric device provides the actual effect. An electric current and a heat flux flow through the material in order to fulfil the function of the overall structure.
- thermoelectric devices in motor vehicles such as automobiles and trucks, in the exhaust system or the exhaust gas recirculation, in order to obtain electrical energy from a part of the exhaust gas heat.
- the hot side of the thermoelectric device is connected to the exhaust gas or tailpipe, while the cold side is typically connected to a cooler.
- the thermoelectric device is installed for use behind the exhaust gas catalytic converter in the exhaust system.
- the amount of electricity which can be generated depends on the temperature of the exhaust gas and the heat flux from the exhaust gas to the thermoelectric material.
- adsorbed natural gas ANG
- CNG compressed natural gas
- a solid, such as activated carbon or metal organic framework material is packed in a vessel to increase the storage density, enabling lower pressure operation with the same capacity or higher amounts of stored gas at the same pressure.
- Sorption which can be adsorption and/or absorption, is an exothermic process. Any sorption or desorption, as well as any compression and decompression, is accompanied by temperature changes in a storage system.
- the heat of sorption has a detrimental effect on performance dur- ing both charge- and discharge cycles of storage vessels, especially when the storage vessel comprises a sorption medium.
- the way of filling a storage system at a fuel station influences strongly the total fuel amount in the storage vessel that is available from the storage vessel at the end of a filling process.
- the fuel temperature in the storage vessel increases due to the heat of compression and/or sorption.
- the temperature in the storage vessel increases during filling to approximately 50°C above ambient temperature due to the heat of compression.
- the temperature in the storage can increase further to an absolute temperature of approximately 90°C due to the additional heat of sorption.
- the temperature increase constitutes a limitation especially for the ANG technique as for example carbon fiber tanks are presently only approved to operate at temperatures to up to 80°C.
- a charge cycle normally will be performed in a fuel station, at least for mobile applications, where the released sorption heat can be removed. Contrary to the charge cycle, the rate of discharge is dictated by the energy demand of the application.
- Heat management system have to be optimized with regard to a minimum of required space and a minimum of additional weight in mobile applications, a minimum of additionally required electrical power and limited costs.
- WO 2014/057390 A1 describes a sorption store for storing gaseous substances, wherein the tank comprises separating elements, which are configured in such a way that the interior of the tank is divided into at least one pair of channels.
- a method for removing gas from the sorption store is described, wherein the channel walls are flowed through by a heat transfer medium.
- thermoelectric module which is thermally conduc- tively connected to a micro-heat exchanger. Further, an exhaust system of an internal combustion engine, preferably of motor vehicles, comprising the thermoelectric module, is described.
- a thermoelectric generator is mentioned to produce electrical energy from heat of exhaust gases. An improved fuel economy can be achieved for a variety of engines including diesel, spark ignition, gas turbine and Stirling. Waste heat utilization concepts can include preheating, regeneration, turbo charging, turbo compounding and Rankine engine compounding. Electrical power, which is produced from the exhaust gas heat can be tapped into a battery to run a dc motor.
- thermoelectric device with an increased energy output and which is able to benefit from temperature changes occurring in a storage vessel comprising a sorption medium.
- thermoelectric device comprising a hot side and a cold side, wherein the hot side is thermally coupled to an exhaust gas system of an internal combustion engine and the cold side is thermally coupled to a storage vessel, wherein a sorption medium is disposed in the storage vessel and the storage vessels contains a fuel for the internal combustion engine.
- thermoelectric device and the storage vessel are mounted to one vehicle, which is driven by the internal combustion engine.
- the internal combustion engine runs with the fuel, which is contained in the storage vessel. Exhaust gas produced by the internal combustion en- gine is led through the exhaust gas system of the vehicle.
- the vehicle can additionally comprise an electric motor with corresponding electric drive system.
- the internal combustion engine is used to drive the vehicle, the fuel is consumed and the storage vessel is emptied while driving.
- An emptying of the storage vessel corresponds to a desorption process in the interior of the storage vessel as the fuel was sorbed to the sorp- tion medium.
- the term "sorption” generally covers adsorption as well as absorption. Sorption is an exothermic process whereas desorption is an endothermic process. Therefore, during driving the vehicle and desorption of the fuel from the sorption medium, the temperature of the sorption medium and the fuel still contained in the storage vessel decreases.
- this temperature decrease can be used to produce electrical energy and to run the thermoelectric device, which uses heat from an exhaust gas system in the vehicle more efficiently. It is a further advantage of the invention that by the described thermal coupling between the storage vessel and the thermoelectric device heat is transferred into the storage vessel. Due to the heat transfer to the storage vessel a larger amount of the fuel can be discharged from the storage vessel as desorption of the fuel from the sorption medium is accelerated. As a smaller amount of the fuel remains in a sorbed state on the sorption medium in the storage vessel, the range the vehicle can cover after one stop for filling the storage vessel is enlarged.
- the cold side is thermally coupled to the storage vessel by a heat exchanger.
- the heat exchanger can be an internal heat exchanger, located in the storage vessel comprising piping loops or double walls in the interior of the storage vessel, which can be filled with a heat transfer fluid. It is also possible to equip the storage vessel with a double wall mantle.
- the heat exchanger is an external heat exchanger applying the fuel from the storage vessel as a first heat transfer medium.
- the storage vessel is equipped with an outlet and an inlet, which both comprise shut-off elements which can be operated separately. During driving, fuel can be taken from the storage vessel via the outlet with the outlet shut-off element open and the fuel taken from the storage vessel can be led through the external heat exchanger.
- a first part of the fuel taken from the storage vessel can further be conducted to the internal combustion engine and a second part of the fuel taken from the storage vessel can be conducted back into the storage vessel through the inlet.
- the two parts of the fuel taken from the storage vessel can be divided before or after a passage trough the external heat exchanger. Both parts or only one of the parts can be conducted through the external heat exchanger.
- the second part of the fuel taken from the storage vessel reentering the storage vessel now has a higher temperature compared to the fuel still stored in the storage vessel. Therefore, the interior of the storage vessel and the sorption medium heat up and further fuel is desorbed from the sorption medium.
- thermoelectric, device is electrically connected to a battery which is electrically connected to an electric motor.
- the internal combustion engine is for example combined with the electric motor as auxiliary drive when the vehicle is a hybrid vehicle.
- vehicle typically comprises rechargeable batteries which, as electrochemical cell, convert chemical energy into electric energy.
- the thermoelectric device is preferably coupled to an electric system, which can comprise the battery and which supplies the electric motor or an air conditioning system or other electrically driven components of the vehicle or combinations thereof. Also a supply from the thermoelectric device to a dynamo of the vehicle might be considered.
- thermoelectric device comprises p- and n-conducting thermoelectric material pieces which are alternately connected to one another via electrically conductive contacts, and the thermoelectric device is thermally conductively connected to a micro heat exchanger, which comprises a plurality of continuous channels having a diameter of at most 1 mm, through which a second heat transfer medium can flow, which is preferably the exhaust gas.
- micro heat exchanger By using micro heat exchangers, it is possible to ensure an improved heat flux from the exhaust gas to the thermoelectric device, with at the same time a sufficiently low temperature loss.
- the term "micro heat exchanger” is intended to mean heat exchangers which have a plurality of continuous channels with a diameter of at most 1 mm, particularly preferably at most 0.8 mm.
- the minimum diameter is set only by technical feasibility, and is preferably of the order of 50 ⁇ , particularly preferably 100 ⁇ .
- the micro channels may have any suitable cross section, for example round, oval, polygonal such as square, triangular or star-shaped, etc.
- the shortest distance between opposite edges or points of the micro channel is considered as the diameter.
- the micro channels may also be formed so as to be flat, in which case the diameter is defined as the distance between the bounding surfaces. This is the case in particular for heat exchangers which are constructed from plates or layers.
- the second heat transfer medium flows through the continuous micro channels while transferring heat to the heat exchanger.
- the heat exchanger is on the other hand thermally connected to the thermoelectric device, so that good heat transfer is obtained from the heat exchanger to the thermoelectric device.
- the micro heat exchanger is formed integrally with the thermoelectric device.
- the micro heat exchanger is formed integrally with the thermoelectric device in a way that the micro heat exchanger has an integrally molded container which receives the p- and n-conducting thermoelectric material pieces, which are alternately connected to one another via electrically conductive contexts, to form an integrated assembly of micro heat exchanger and thermoelectric device.
- the micro heat exchanger and container may be constructed in any suitable way from any suitable materials. It may for example be made from a block of a thermally conductive material, into which the continuous channels are introduced.
- Suitable materials are for example plastics, for example polycarbonate, liquid crystal polymers such as Zenith ® from DuPont, polyether ether ketones (PEEK), etc.
- Metals may also be used, such as iron, copper, aluminum or suitable al- loys such as chromium-iron, Fecralloy®.
- Ceramics or inorganic oxide materials may furthermore be used, such as aluminum oxide or zirconium oxide or cordierite. It may also be a composite material made of a plurality of the aforementioned materials.
- the micro heat exchanger is preferably made of a high temperature-resistant alloy (1000-1200°C), Fecralloy®, iron alloys containing Al, stainless steel, cordierite.
- the microchannels may be introduced into a block of a thermally conductive material in any suitable way for example by laser methods, etching, boring, etc.
- the micro heat exchanger and container may also be constructed from differ- ent plates, layers or tubes, which are subsequently connected to one another, for example by adhesive bonding or welding.
- the plates, layers or tubes may in this case be provided in advance with the microchannels and then assembled.
- the container which receives the p- and n-conducting thermoelectric material pieces is integrally moulded to at least one of the plates, layers or tubes.
- the micro heat exchanger and container from a powder by means of a sintering method.
- Both metal powders and ceramic powders can be used as the powder. Mixtures composed of metal and ceramic, composed of different metals or composed of different ceramics are also possible. Suitable metal powders comprise, for example, powders composed of ferritic steels, Fecralloy® or stainless steel.
- SLS Selective Laser Sintering
- micro heat exchanger and container affords the advantage of a good thermal conductivity.
- ceramics have a good heat storage capability, and so they can be utilized, in particular, to compensate for temperature fluctuations.
- plastics are used as material for the micro heat exchanger and container, it is necessary to apply a coating that protects the plastic from the temperatures of the exhaust gas flowing through the micro heat exchanger. Such coatings are also referred to as "thermal barrier coating”. On account of the high temperatures of the exhaust gas, it is necessary to coat all surfaces of the micro heat exchanger composed of the plastics material.
- External dimensions of the micro heat exchanger are preferably from 60 x 60 x 20 to 40 x 40 x 8 mm 3 .
- the specific heat transfer area of the micro heat exchanger, in relation to the volume of the micro heat exchanger, is preferably from 0.1 to 5 m 2 /l, particularly preferably from 0.3 to 3 m 2 /l, in particular from 0.5 to 2 m 2 /l.
- Suitable micro heat exchangers are commercially available, for example from the Institut fur Mikrotechnik Mainz GmbH (IMM).
- the IMM offers various geometries of microstructured heat exchangers, and in particular microstructured high-temperature heat exchangers for a maximum operating temperature of 900°C.

- thermoelectric material 5 to 6 % of heat taken from an exhaust gas stream can be transformed into electric energy. This value is predominantly limited by the selection of the thermoelectric material. Especially suitable materials can provide a transformation of up to 10 %. At a temperature difference between 100°C and 650°C, commercially available materials can provide an efficiency of 6 to 7 % for the transformation of heat into electric energy. Considering heat losses in the system, an overall efficiency of 5 % can be achieved. Typically a cooling capacity of 10 to 15 kW is required on the cold side of the thermoelectric device for applications in cars.
- a protective layer for protecting against excessive temperatures is provided between the thermoelectric device and the micro heat exchanger.

- Suitable metal salts are for example fluorides, chlorides, bromides, iodides, sulfates, nitrates, carbonates, chromates, molyb- dates, vanadates and tungstates of lithium, sodium, potassium, rubidium, cesium, magnesium, calcium, strontium and barium. Mixtures of suitable salts of this type, which form double or triple eutectics, are preferably used.
- thermoelectric device may be encapsulated with the protective layer, in particular when using metals such as nickel, zirconium, titanium, silver and iron, or when using alloys based on nickel, chromium, iron, zirconium and/or titanium.
- the micro channels of the micro heat exchanger are coated with a motor vehicle exhaust gas catalyst.
- the micro channels are preferably coated with an exhaust gas catalyst, which in particular catalyzes one or more of the conversions: NOx to nitrogen, hydrocarbons to C0 2 and H 2 0, and CO to C0 2 . Particularly preferably, all these conversions are catalyzed.
- Suitable catalytically active materials such as Pt, Ru, Ce, Pd are known, and are described for example in Stone, R. et al., Automotive Engineering Fundamentals, Society of Automotive En- gineers 2004. These catalytically active materials are applied in a suitable way onto the micro channels of the micro heat exchanger. Preferably, application in the form of a washcoat may be envisaged. In this case, the catalyst is applied in the form of a suspension as a thin layer onto the inner walls of the micro heat exchanger, or onto its channels. The catalyst may then consist of a single layer or various layers with identical or varying composition. The applied catalyst may then fully or partially replace the normally used exhaust gas catalytic converter of the internal combustion engine during use in a motor vehicle, depending on the dimensioning of the micro heat exchanger and its coating.
- thermoe- lectric device Due to the washcoat directly provided in the micro heat exchanger, the hot side of the thermoe- lectric device can be further heated up, due to the catalyzed reaction occurring at the washcoat.
- the micro heat exchanger may be installed in the exhaust system at the position of the original exhaust gas catalytic converter. In this way, a high exhaust gas temperature can be supplied to the micro heat exchanger. The temperature may be increased even further by the chemical conversion at the exhaust gas catalyst of the micro heat exchanger, so that much more efficient heat transfer takes place than in known systems.

The pressure loss in the exhaust system of the internal combustion engine is low, in particular when the micro heat exchanger is coated with the washcoat of the exhaust gas catalyst.
- the structure of the exhaust system can be simplified significantly by the one integrated component. Since the integrated component can be integrated closer to the internal combustion engine in the exhaust system, higher exhaust gas temperatures can be supplied to the thermoelectric device. By the reverse use of the thermoelectric device as a Peltier element, the exhaust gas catalyst can be heated during a cold start of the engine.
