Abstract

Non-combustion thermal motor with a rotary cycle of condensable fluid in a closed circuit powered by the energy of a temperature difference. # The system is a rotary motor based on the heating and cooling of a fluid immersed in a closed circuit, where the hot zone of the An engine in which heat is supplied causes the gas to increase the pressure and tends to expand through a zone of rotating blades. Once expanded it cools in an area with heatsinks and another area of rotating blades attached to the same axis of expansion compresses it again to take it to its initial situation.

DESCRIPTION

Non-combustion thermal motor with a rotary cycle of condensable fluid in a closed circuit powered by the energy of a temperature difference.

Object of the invention

The object of the invention is to take advantage of only a temperature difference external to the engine to perform a job. In this way the residual heat of any operation, or the heat of the sun, can be used more efficiently. Given that concentrating solar rays is relatively easy, it is only necessary to find a temperature difference for the rotor to rotate and perform work.

This would simplify the fact that anyone can use a temperature difference to get energy, without going through the difficulties of steam boilers, or combustion.

Another use would be to take advantage of heat and cold cycles for convenience, such as a heat pump in a home.

Background of the invention

The steam engine was the first machine that used external heat to do a job. Currently turbines are used to perform work through water vapor or gas combustion. There is a thermal engine without internal combustion, Stirling, which uses an alternate movement but uses non-condensable fluids. This report explains the operation of a fluid-driven rotary cycle thermal engine that can be condensable and that uses only the energy of a temperature difference.

The performance of an ideal thermal engine according to Sadi Carnot is based on the difference between temperatures. Therefore, the greater the difference in temperature contributed, the greater the yield.

The fact that there are incombustible and condensable gases that significantly change their pressure before a minimum temperature difference makes this engine possible. An example of these gases is any non-combustible refrigerant gas, but also the air.

Description of the Invention 40

The engine consists of two main parts, one where the fluid is heated and another where it cools.

In the hot part the energy source is provided in the form of heat to a chamber that surrounds the expansion part of the engine. The fluid is introduced into the engine, and when heated it moves the blades in the direction of the area of least pressure, as if it were a turbine. Only that this turbine sucks fluid and heats it inside itself, through its walls or the stator. So it creates a rotational movement in the axis of the blades. Once the necessary blades have been run, the expanded and hot fluid passes to the cooling zone where other blades in the cold zone go.

sucking and compressing to cool again to re-enter the heating zone. These compression blades use the movement of the rotor to compress the fluid again, and it is necessary to cool to absorb the heat of compression. In this way, the blades in the expansion zone provide a work on the rotating rotor, and part of this work is used in the cold zone to reintroduce it 5 tablets. The rest of the work is usable, discounting friction. That is why it is fulfilled that the greater the temperature difference between the cold and hot zone of the engine, the greater the performance is obtained.

Description of a preferred embodiment 10

We have a kind of turbine and outside it is surrounded by a chamber (2) where we circulate hot thermal oil from a solar collector or residual heat. The working fluid would be a non-combustible refrigerant gas under pressure. The fluid would be before entering the engine in a liquid state, and upon entering the engine (1) it would go into a gaseous and warming state. The increase in pressure due to the heat supplied causes the gas to circulate to an area of lower pressure to expand. To reach that area you must cross all the blades (3) that are necessary, depending on the expected temperature difference. And it also crosses all the stators or walls of the turbine where heat is supplied. In this way the blades give the rotor a rotating movement 20.

Once the expansion blades have passed, the gas passes to a chamber where the heat input is removed, therefore it cools to ambient air. Depending on the heat applied, this chamber will be more or less large or it will be necessary to introduce the necessary heat sinks (4).

After this chamber the same rotor moves other blades (5) that compress the gas again to reinsert it into a tube in a liquid state (6). This would be the compression zone, where it is important to apply the coldest temperature, to also remove the heat from the compression of the gas.

It is interesting to have a reservoir (7) to accumulate condensed fluid at low temperature. So much for the continuity of work of the engine, as to deposit lubricants, as well as to have gas to cool for direct use. 35
