Definitions
- the invention relates to a method for transferring thermal energy, the thermal energy being introduced via a first heat exchanger into an interior of a rotating centrifuge, in which interior there is a gaseous energy transfer medium, and wherein the heat is removed from the centrifuge via a second heat exchanger.
- thermodynamic cyclic processes make it possible to transport thermal energy from a medium which is at a low temperature to a medium which is at a higher temperature.
- Such cycles are used for example in cooling devices, heat pumps and the like.
- the supply of energy is necessary to maintain the cycle.
- the aim of the present invention is to provide a method and a device with which such a cycle process for heat transport from a low temperature to a higher temperature is possible, the energy used for this being significantly reduced.
- Such a method can be used on the one hand for cooling and on the other hand for heating similar to a heat pump, if it is possible to extract heat from another medium, such as is the case when geothermal energy is used.
- the object of the present invention is to minimize the energy expenditure which is necessary for transporting thermal energy from a state of lower temperature to a state of higher temperature. Another object of the invention is that such a method is simple to carry out and that the required device is inexpensive, feasible and has a simple structure.
- the method is characterized in that the gaseous energy transmission medium in the interior of the rotor is in a state of equilibrium and in that the heat flow is directed radially outward.
- the temperature of the energy transfer medium increases from the inside to the outside and that the temperature difference of the energy transfer medium between the inner region of the rotor and the outer region of the motor is at least 5 K, preferably at least 50 K, particularly preferably at least 100 K and further particularly preferably at least 200 K. In this way, optimal efficiency can be achieved.
- the heat transport in the rotor takes place primarily by heat conduction.
- Radiation effects within the energy transfer medium in the rotor can also play a role in the solution according to the invention.
- the extent of the radiation effects occurring depends essentially on the average temperature level of the geometric design of the rotor, on the type of gas and on the nature of the surfaces of the gas space.
- the highest degree of efficiency is achieved when the thermal conductivity effects dominate. It is essential for the invention, however, that convection currents conditions are largely prevented since they are disadvantageous for the exploitation of the effects according to the invention.
- a cyclical process in which losses due to transient effects can largely be avoided is achieved in that the rotor is operated at an essentially constant speed.
- the invention relates to a device for transferring thermal energy with a rotor, which has an interior space which is filled with a gaseous energy transfer medium, a first heat exchanger being provided in the region of the axis of the rotor and one in the region of the outer circumference of the rotor second heat exchanger is provided, which two heat exchangers are in contact with the gaseous energy transfer medium.
- the device is characterized in that the gaseous energy transmission medium is in a state of equilibrium in the interior of the rotor.
- the achievable temperature difference can be increased in that several rotors are provided and that a device for energy transfer from the second heat exchanger of a first rotor to the first heat exchanger of a further rotor is provided.
- a device for energy transfer from the second heat exchanger of a first rotor to the first heat exchanger of a further rotor is provided.
- the first rotor and the further rotor are filled with different energy transmission media.
- each stage can be optimized for itself depending on the average temperature level within this stage.
- a mechanically simple structure is achieved in this context in particular by the fact that the rotors are firmly connected to one another.
- Thermal losses can be avoided in a particularly preferred manner by accommodating at least one rotor in an insulated protective jacket.

- Fig. 1 is a schematic representation of a device according to the invention
- Fig. 2 and Fig. 3 diagrams to show the pressure and temperature curve at rest or in operation
- Fig. 4 is a schematic representation of a rotor of another embodiment of the invention.
- the apparatus of Fig. 1 comprises a drive motor 1 and a rotor designed as a centrifugal separator 2, which can be rotated at high speed, for example at 10,000 min "1 in rotation.
- the rotor 2 has an annular inner space 3, in the inside, a first heat exchanger 4 and the outside, a second heat exchanger 5 are located.
- the radius in respect to the axis la of the apparatus is designated by ⁇ , and for the second heat exchanger 5 r a to the internal heat exchanger 4. in the interior space 3 while a suitable gas is sealed.
- the diagram of FIG. 2 shows the pressure and temperature profile of the gas in the interior of the interior 3 in the idle state, ie without rotation.
- a constant pressure p 0 is established in the interior 3, and without the addition or removal of heat via the heat exchangers 4 and 5, a temperature equilibrium is established at the temperature T 0 , which is shown with a solid line in FIG. 2.
- a temperature gradient is formed in a known manner, which is shown in accordance with the broken line Ti in the diagram in FIG. 2.
- the steepness of the temperature gradient depends mainly on the heat flow and the geometry of the rotor 2 and the thermal properties of the gas in the interior 3.
- the heat flows in a manner known per se from a state of higher temperature to a state of lower temperature.
- FIG. 3 shows the pressure and temperature curve during operation of the device according to the invention. Due to the centripetal acceleration occurring during the rotation, the pressure p r of the gas in the interior 3 increases towards the outside and reaches its outer diameter r a of the interior 3 greatest value. A similar curve profile results for the temperature T r0 of the gas in the interior 3, which is shown in FIG. 3 with a solid line. The temperature rises continuously from a temperature T i0 on the inner diameter ⁇ to a temperature T a0 at r a .
- the heat exchanger 4 can be operated at a lower temperature than the heat exchanger 5.
- the heat exchanger 4 can be arranged in a cooling circuit and the heat exchanger 5 essentially dissipate the heat to the environment.
- the heat exchanger 4 can be connected to a heat source at ambient temperature, and the heat exchanger 5 can be used to deliver heat at a correspondingly higher temperature level.
- FIG. 4 shows a rotor 12 of another embodiment variant of the invention.
- Two inner spaces 3a, 3b are provided side by side in the rotor 12, each of which is provided on the inside with a first heat exchanger 4a, 4b and on the outside with a second heat exchanger 5a, 5b.
- the rotor 12 has an insulating layer 6 on the outside to avoid heat losses.
- the heat transfer media for feeding the heat exchangers 4a, 4b; 5a, 5b are preferably fed in or discharged axially, with 7 schematically denoting a first line for supplying a first heat exchanger 4a, and 8 denoting a second line through which the heat exchanger 5a opposite the first heat exchanger 4a and the other first Heat exchanger 4b is connected and with 9 a line through which the heat from the second heat exchanger 5b is removed from the rotor 12.
- the lines 7, 8, 9 only indicated here each consist of a supply and discharge line and that corresponding pumps or the like for circulating the heat exchanger media are provided, which are not shown here for reasons of simplification.
- the device according to the invention makes it possible to provide a thermodynamically highly effective device which can be used in many different ways.
