The invention is intended for power supply of agricultural production facilities, communication and control systems, in other areas of the national economy, in everyday life. The device contains a temperature sensor and a housing, in one part of which there is a combustion chamber, and the other part is communicating with the outside air. At the top they are connected by an exhaust pipe with the atmosphere. Hot junctions of the temperature sensor are located in the combustion chamber, and cold junctions in the other part of the body are covered with a layer of porous material and hydraulically connected to an ice cold accumulator. The invention provides conversion of thermal energy into electrical energy at the maximum temperature difference between junctions. This increases the efficiency of the device and its efficiency.
DESCRIPTION OF THE INVENTION
The invention relates to the field of creating power supplies and can be used for power supply to emergency and other objects of agricultural consumers, including communication and control systems. Can be used in other areas of the national economy and life.
And the invention is aimed at the implementation of the scientific and technical program for the integrated use of natural cooling in agriculture, an important renewable and environmentally friendly energy source in Russia.
One form of such use is the direct conversion of thermal energy into electrical energy, while ensuring the maximum thermal difference between natural natural bodies that store cold and heat, such as water, ice, air.
A device is known for powering consumers using natural cold, used as low-power electric power sources for feeding autonomous ocean buoys. It uses for the generation of electric power the temperature difference between the deep and surface layers of water (RU N 2031486 C1, 20.03.95. H01L 35/02).
The disadvantage of this device is the large redundancy of the element base and the design features that do not allow it to be effectively used on agricultural objects. In addition, it lacks a difference in the temperature of the refrigerants, since the natural cold accumulated in the form of ice water or ice is not used.
The closest in technical essence to the present invention is an apparatus for powering objects comprising a temperature sensor (thermoelectric batteries), a current collector, conductors, a cold accumulator (RU 2018196 C1, 15.08.94, H 01 L 35/22).
The disadvantage of this device is the relatively high temperature of the "cold" junction of the temperature sensor, obtained during operation, and the decrease in the efficiency and electric power due to this. This negatively affects the efficiency of the use of devices for power supply to agricultural consumers.
The technical goal of the invention is to increase the efficiency and efficiency of devices to provide power to more powerful, including agricultural consumers, by more fully utilizing the potential of naturally cold natural agents, in particular bodies that store natural cold in the form of ice and ice water.
In order to achieve this technical result, the power supply device comprising the temperature sensor, the current collector, the conductors, the cold storage battery is characterized in that it comprises a housing in which a combustion chamber is located in a part of which, coated with a thermal insulation layer, the cold junctions of the temperature sensor are located in the inner part of the housing connected With external air, and are covered with a layer of porous material hydraulically connected to the water-ice accumulator, and the hot junctions of the temperature sensor are placed in the combustion chamber, the upper parts of the combustion chamber and the inner part of the housing connected by an exhaust pipe to the atmosphere.
As a result of using the invention, the temperature difference of the cold and hot junctions of the thermobattery increases, the specific electric power increases and the material consumption of the device for supplying consumers, mainly agricultural consumers, decreases.

The invention is explained in the drawings, in which FIG. 1 schematically shows an apparatus for power supply, a general view, FIG. 2 - a temperature sensor in a section.
The device comprises a housing 1, an ice cold accumulator 2, a thermal sensor 3, conductors 4 electrically connected to a temperature sensor 3 electrically connected to the terminals of the current collector pad 5. A combustion chamber 7 is arranged in the housing part 1 covered with a thermal insulation layer 6. Cold junctions 8 of the temperature sensor 3 are located in the inner part 9 of the body 1 connected to the outside air and are covered with a layer 10 of the porous material hydraulically, for example by a hose 11 connected to a cold accumulator. Hot junctions 12 of the temperature sensor 3 are placed in the combustion chamber 7. The upper parts of the combustion chamber 7 and the inner part of the body 1 are connected by an exhaust pipe 13 to the atmosphere. In the combustion chamber 7 there are devices for burning both solid and gaseous fuels, including from local materials.
The porous material layer 10 may be hydraulically connected to the water supply source, but cooling of the junctions 8 in this case is less effective than the water-ice mixture from the cold accumulator 2.
The device for powering consumers using natural cold operates as follows:
Chilled water from the water-ice accumulator 2 or the water supply system enters the layer 10 of the porous material covering the cold junctions 8 of the temperature sensor 3 and is absorbed by it as a wick. In the same zone, external air is drawn in, drawn by the exhaust pipe 13, into which hot gases from the combustion chamber 7 are supplied.
The gases from combustion along the exhaust pipe 13 escape into the atmosphere, "pulling" the outside air, the blowing layer 10 of the porous material. The generated heat heats the hot junctions 12 of the temperature sensor 3.
When the porous material is blown by the outside air, the cooled water evaporates intensively, cooling the cold junctions 8 of the temperature sensor 3.
In accordance with the Seebeck effect, a difference in electrical potentials between the conductors 4 of the current collector pad 5 feeds the consumer's electrical receivers.
The generated electricity is of high quality, that is, low level of interference and high tension. This is especially important for powering communication and control systems, including in emergency modes.
