The invention relates to electric power sources and is a device for direct conversion of thermal energy into electrical energy. The electric current is generated in an electrical circuit consisting of the p-branches 1 and n-branches of the thermocouple 2, the switching plates 3 and the active load 6, due to the temperature difference on the hot 4 and cold 5 junctions when placed in the cavity of the hot stream 8 and the cavity Of the cold flow 9 of the vortex tube 7 obtained as a result of the temperature separation of the gas coming from the compressed gas source. Thus, the operation of the thermoelectric generator does not require the combustion of fuel, and the environmental and fire safety of electricity generation is improved.
DESCRIPTION OF THE INVENTION
The invention relates to electric power sources and is a device for direct conversion of thermal energy into electrical energy.
The closest device of the same designation to the claimed invention is a thermoelectric generator (TEG), comprising an electrical circuit consisting of p and n branches of a thermoelement (having different signs of thermoelectromotive force), switching (connecting) plates, hot and cold Junctions and active load, in which the consumption of the electric power produced by the thermoelement occurs (see Eordanishvili, EK, Thermoelectric Power Sources, Moscow: Soviet Radio, 1968. P.23, Fig. 4, Fig. 1), and adopted for prototype.
The reasons preventing the achievement of the following technical result when using a known thermoelectric generator (TEG), taken as a prototype, is that its work is provided by burning fuel to heat hot junctions, which is associated with fire hazard and pollution of the environment by the combustion products of the fuel. In addition, the efficiency of cooling cold junctions with natural convection in the environment is quite low, and the use of heat exchangers for cooling significantly increases the cost of electricity.
The technical result is fuel economy, reduction of environmental pollution by combustion products, increase of fire safety of the thermoelectric generator.
Said technical result in the practice of the invention is achieved by the fact that in the proposed thermoelectric generator comprising an electric circuit consisting of p and n branches of the thermoelement (having different signs of the coefficient of thermoelectromotive force), switching plates, hot and cold junctions and an active load , In which the electrical energy released by the thermoelement is consumed, the feature is that hot junctions are placed in the cavity of the hot vortex tube flow, and cold junctions into the cavity of the cold flow of the vortex tube formed in the vortex tube during the temperature separation of the compressed gas.
The applicant's prior art analysis, including the search for patent and scientific and technical information sources, and the identification of sources containing information about the analogues of the claimed invention, made it possible to establish that the applicant did not find an analogue characterized by features identical to all the essential features of the claimed invention. The determination from the list of identified analogues of the prototype, as the closest in the aggregate of the essential characteristics of the analogue, made it possible to identify a set of essential characteristics with respect to the result to be observed in the claimed device, set forth in the claims. Therefore, the claimed invention corresponds to the condition of "novelty".
In order to verify the compliance of the claimed invention with the "inventive step" condition, the applicant conducted an additional search for known solutions to identify features that coincide with the features of the claimed device that are distinct from the prototype.
The results of the search have shown that the claimed invention does not clearly follow from the prior art for a specialist, since the prior art defined by the applicant has not revealed the effect of the transformations required by the essential features of the claimed invention to achieve a technical result, in particular the claimed invention does not provide the following transformations:
- the addition of a known means by any known part (parts), attached (attached) to it according to known rules for achieving a technical result, in respect of which it is determined precisely such additions;
- replacement of any part (parts) of the known means with another known part to achieve a technical result, in respect of which the effect of such a substitution has been established;
- the exclusion of any part (element) of the facility with the simultaneous exception of the function due to its presence and the achievement of the usual result for such an exception (simplification, reduction of mass, dimensions, material intensity, increase in reliability, etc.);
- an increase in the number of the same type of elements to enhance the technical result due to the presence in the facility of just such elements;
- the execution of a known means or a part (s) thereof of a known material to achieve a technical result due to the known properties of this material;
- the creation of a means consisting of known parts, the choice of which and the relationship between which are implemented on the basis of known rules, recommendations, and the resulting result is due only to the known properties of parts of this tool and the connections between them.
The described invention is not based on changing the quantitative characteristic (s), the representation of such characteristics in the relationship or a change in its type. This refers to the case when the fact of influence of each of the indicated characteristics on the technical result is known, and new values of these characteristics or their interrelation could be obtained proceeding from known dependencies, regularities.
Therefore, the claimed invention corresponds to the condition "inventive step".
