Definitions

  • the invention relates to a device for photothermal heating of a thermal energy converter with a transparent collector opening, a thermal contact point of the thermal energy converter and an optical element located in between.
  • thermoelectric generators as thermal energy converters
  • LIS20210202816A1 shows such a device in which a solar concentrator directs sunlight directly onto the hot side using optical elements such as mirrors or lenses, bundles infrared radiation onto a heat collector or couples it into a fiber optic cable.
  • the heat collected in the heat collector is used to heat air, which is used to heat the hot side of the Seebeck element to generate electricity.
  • the collected light can be coupled into the fiber optic cable and directed to the hot side.
  • the invention is therefore based on the object of simultaneously extracting the energy from a plurality of frequency ranges in a manner adapted to the respective frequency range using structurally simple means and with the lowest possible energy loss, and thereby minimizing mutual impairments of the energy extraction.
  • the invention solves the problem in that an interior space adjoins the collector opening along a main propagation direction of the incident light, which is delimited by the thermal contact point running in the main propagation direction and in which the light, which is at least partially surrounded by a heat accumulator, partially directs the light towards the thermal contact point reflecting and partially transmitting in the heat accumulator optical element is arranged.
  • the light penetrates the device via the collector opening along the main propagation direction and hits the optical element, which, due to its material and its arrangement in the optical path, reflects the high-frequency component of the light to the thermal contact point, while the low-frequency component of the light is reflected is transmitted to the heat accumulator.
  • the high-frequency component After reflection, the high-frequency component hits the thermal contact point, where the energy stored in the light is released to the thermal contact point in the form of heat. Since the direction of the high-frequency component changes more strongly in relation to the main propagation direction when it hits the optical element due to diffraction, refraction, reflection, etc. than in the case of the low-frequency component, the thermal contact point runs in the main direction of propagation, since this increases the effective cross section of the thermal contact point in the optical path of the high-frequency light.
  • the optical element is preferably designed in such a way that the portion of the light reflected onto the thermal contact point is bundled when it strikes the thermal contact point, in order to bring about a strong local temperature increase.
  • the low-frequency portion of the light is transmitted into the heat accumulator surrounding the optical element, impinges on it and gives off its energy to it as heat energy.
  • both the thermal contact point and the heat medium can be optimized for energy absorption in one frequency range, since the light of the complementary frequency range is efficiently absorbed by the other element in each case.
  • the heat accumulator is thermally conductively connected to the thermal contact point, so that the thermal energy absorbed in the heat accumulator can be released to the thermal contact point. Since the volume of the heat accumulator exceeds the volume of the thermal contact point many times over and the heat accumulator surrounds the optical element, the energy yield is increased compared to the prior art.
  • both the high-frequency and the low-frequency light component that does not emit energy in the intended manner or escapes from the device in an undesirable manner through scattering, reflection, diffraction, etc. via the collector opening inevitably either in transmitted to the heat accumulator, reflected onto the thermal contact point, or absorbed by the walls of the interior and thus transfers its energy to the device.
  • Another advantage of the device is that the heat accumulator still gives off its stored heat energy to the thermal contact point when no more light is shining through the collector opening, so that the heat energy converter can continue to be operated in this case because the heat energy absorbed by the heat accumulator is delivered to the thermal contact point of the thermal energy converter even without incident light.
  • the interior can be arranged within a compact housing, which is preferably thermally insulated from the outside.
  • the optical element can be a prism or, for example be a semi-transparent mirror.
  • the incident light can be divided into high- and low-frequency components depending on the light source and the materials used and does not have to be an absolute classification; it is only important that the high-frequency component of the light is in a higher frequency spectrum than the low-frequency component. It is self-evident that the spectrum of light visible to the human eye is not necessarily the only concern, but that infrared and ultraviolet radiation, for example, are also included in the use of the term “light” according to the invention.
  • the term thermal energy converter means any device that can convert the thermal energy obtained with the device into another form of energy.
  • the thermal energy converter can therefore be a thermoelectric generator, for example.
  • This thermoelectric generator can be a Seebeck element, which converts thermal energy into electrical energy.
  • the thermal energy can be used to generate steam and operate a turbine, so that the thermal energy is converted into mechanical and optionally subsequently into electrical energy.
  • the optical element does not necessarily lie in the optical path of all incident light beams, only part of the incident light can be reflected or transmitted according to the invention.
  • the inner wall of the interior space be designed to be reflective, at least in sections.
  • the reflective inner wall is thermally conductively connected to the heat accumulator, so that this absorbed energy can also be supplied to the heat accumulator.
  • the free inner wall of the interior be designed to be reflective.
  • the free inner wall is the inner wall that is not formed by built-in components such as the thermal contact point or shaded by such built-in components. This free inner wall can consequently be provided with the largest possible reflective surface without impairing other components of the device, such as the thermal contact point.
  • the device can be designed to be translucent in the main propagation direction if an emitter opening delimiting the interior space is opposite the collector opening in the main propagation direction. As a result of these measures, part of the light running in the main propagation direction can pass through the device and exit again from it. Although this reduces the efficiency of energy extraction, it allows the device to be integrated in transparent surfaces, such as glass doors, windows or facades, so that these surfaces can be used for energy generation. In addition, several devices according to the invention can be connected in series in this way.
  • the collector opening preferably has a plurality of converging lenses arranged in a grid, so that the beam path of the incident light can be defined largely independently of the location at which the light strikes the collector opening.
  • the device can be designed as compact as possible in combination with the thermal energy converter if the thermal energy converter comprises a Seebeck element, preferably several Seebeck elements, the heated end of which forms the thermal contact point or is thermally conductively connected to it.
  • Seebeck elements have large-area heated ends with low thicknesses.
  • the heated end as a thermal contact point of a Seebeck element already forms a large irradiation cross-section for the reflected light and can therefore easily absorb energy without further modifications.
  • the small thickness of the Seebeck element, running orthogonally to the heated end thus enables a compact combination of thermal energy converter and the device. If the heated end of the Seebeck element or elements is thermally conductively connected to the thermal contact point, the Seebeck element or elements can be arranged outside of the device and can therefore be replaced more easily.
  • the cold end of the Seebeck element or of the Seebeck elements can be cooled, for example, by means of cooling fins and/or fans, or it can be connected to the ground as a heat sink.
  • a Seebeck element is understood to mean a thermal energy converter which uses the Seebeck effect to obtain electrical current from a temperature difference and which can be constructed similarly to a Peltier element. Since Seebeck elements are usually compact, it is advisable to connect several Seebeck elements to the thermal contact point in a thermally conductive manner in order to increase the energy yield of the device.
  • the thermal energy converter can include a reservoir for an energy carrier fluid, which is thermally conductively connected to the thermal contact point.
  • the heat energy transferred to the thermal contact point is fed via the thermal line to the energy carrier fluid and thus to the reservoir, which heats up.
  • This heated energy carrier fluid already serves as a heat store, so that energy can still be converted when there is no longer any light input into the device.
  • a heat engine or one or more Seebeck elements, for example, can subsequently be operated with the heated fluid.
  • the supplied heat cannot be completely converted into mechanical energy, part of the supplied heat remains in the energy carrier fluid. In contrast to other energy stores, however, this can be easily transported, for example by being pumped through tubes, with which the waste heat can be used to operate a heating system, for example.
  • the energy carrier fluid is water.
  • the thermal energy converter include a steam turbine.
  • the energy carrier fluid can be further heated via the phase transition from liquid to gaseous, as a result of which the energy density of the energy carrier fluid can be increased.
  • the gas can subsequently be used to operate a steam turbine, in which case the waste heat from the energy carrier fluid can also be used in both states of aggregation.
  • water is preferably used as the energy carrier fluid.
  • the thermal contact point can still be heated with the heat energy stored in the heat accumulator even when no more light is shining through the collector opening.
  • the period over which the stored thermal energy is released can be further increased if the heat store is a latent heat store. Since the thermal energy supplied to the latent heat storage device is used not only for a temperature increase but also for a phase transition from a phase of lower energy to a phase of higher energy, thermal energy can continue to be supplied from a certain phase transition temperature in a transition area without causing a further increase in temperature.
  • the latent heat storage device gives the Energy that is released during the transition from the phase of higher energy to the phase of lower energy decreases slowly, since the phase transition and thus the transfer of the latent heat to the thermal contact point can extend over a longer period of time.
  • the incident light can be divided particularly easily into the low-frequency and high-frequency components and forwarded accordingly if the optical element is a prism which has a surface facing the collector opening and a surface facing the thermal contact point.
  • the dispersive behavior of the prism is exploited and the light can be divided by a simple and easy-to-manufacture optical element via the angle of incidence and the frequency-specific refractive index.
  • the beam path can be easily optimized via the position of the prism in the interior through testing, calculation or simulation.
  • the inclination of the prism with respect to the main direction of incidence can be adjusted.
  • the prism can be rotatably mounted.
  • the prism preferably has a triangular base area, with the area facing neither the collector opening nor the thermal contact area running at an angle to the main propagation direction. This surface can thus preferably face the emitter opening.
  • the free interior space i.e. the interior space with the exception of the optical element and any other built-in components, be completely filled with the heat accumulator. Since, as a result of these measures, the largest possible volume of the interior is filled with heat storage, more heat energy can obviously also be stored.
  • the optical element can preferably be connected directly to the collector opening and/or to the thermal contact point, so that the high-frequency component of the light is reflected onto the thermal contact point and not into the heat accumulator is steered.
  • a heat accumulator can be selected whose material only minimally influences the high-frequency component in terms of its beam path and its intensity.
  • the heat accumulator is translucent, so that the device is still translucent in the main direction of propagation, despite the heat accumulator.
  • water can be used to store heat.
  • the water can be filled into the interior and the collector and any existing emitter opening can be closed with a translucent material, such as a translucent plastic plate.
  • the optical element can also be completely surrounded by the heat accumulator.
  • the thermal energy converter includes a reservoir for water as the energy carrier fluid
  • this reservoir can be fluidly connected to the heat accumulator, so that the thermal energy is not only fed into the energy carrier fluid by thermal conduction, but also by convection.
  • the amount of energy that can be extracted from the incident light with a constant size of the collector opening can be increased by combining several devices to form a thermal power plant, in which the emitter opening of one device connects to the collector opening of a device downstream in the main propagation direction.
  • the interiors of the individual devices of the thermal power plant form a large common interior area, with the light only being able to escape through the collector opening of the first device and the emitter opening of the last device, regardless of the number of combined devices and thus the size of this interior area.
  • the volume of the interior increases while the exit area bounded by the collector opening and the emitter opening remains the same.
  • the combination of several devices in the thermal power plant according to the invention can thus increase the probability of the light being present in the thermal power plant, and thus the energy that can be drawn.
  • the thermal power plant can thus increase the probability of the light being present in the thermal power plant, and thus the energy that can be drawn.
  • Probability of presence can be further increased by the last device in the thermal power plant being followed by a reflecting or absorbing wall, so that the light does not reach the thermal power plant via the last emitter opening can leave.
  • the optical elements of successive devices in the thermal power plant can have a different refraction, reflection or diffraction behavior, so that in the main direction of propagation successively lower-frequency components of the incident light are diverted to the thermal contact points.

  • the thermal contact points of at least two devices are thermally conductively connected to a common reservoir for an energy carrier fluid.
  • the energy carrier fluid can not only be tempered more evenly, namely by convection within the reservoir, but heat losses are also minimized, since a common reservoir clearly has less surface area over which heat can radiate unused than several small reservoirs.

L'invention concerne un dispositif pour le chauffage photothermique d'un convertisseur d'énergie thermique, comprenant une ouverture de collecteur laissant passer la lumière (1), un point de contact thermique (3) du convertisseur d'énergie thermique et un élément optique intercalé (5). Pour concevoir un dispositif du type défini au début, de sorte que, avec des moyens simples du point de vue de la construction et avec des pertes d'énergie aussi faibles que possible, l'énergie d'une pluralité de plages de fréquence puisse être prélevée simultanément d'une manière adaptée à la plage de fréquence respective, et que la perturbation réciproque du prélèvement d'énergie soit ainsi réduite au minimum, on propose qu'un espace intérieur (4) soit adjacent à l'ouverture de collecteur (1) le long d'une direction de propagation principale (2) de la lumière incidente, ledit espace intérieur étant délimité par le point de contact thermique (3), qui s'étend dans la direction de propagation principale, et au sein duquel est agencé l'élément optique (5), qui est entouré, au moins dans certaines sections, par un accumulateur de chaleur (6) et qui réfléchit une partie de la lumière vers le point de contact thermique (3) et transmet une partie de la lumière à l'intérieur de l'accumulateur de chaleur (6).
