TECHNICAL FIELD

The invention relates to a heat exchanger motor and electronic control method that generates energy with heat exchangers using heat difference without any fuel consumption.

BACKGROUND

Nowadays, many countries import a large part of their energy needs. Therefore, the money spent on energy is also very high. The high energy expenditure and the emissions emitted by energy production systems can be defined as problems. These problems can be solved with different methods and energy costs and emissions can be reduced as much as possible. It is very important that energy production systems must work as efficiently as possible, both economically and environmentally. Thus, emissions and air pollution will be reduced while reducing energy costs.

Various heat exchanger motors have been developed to reduce energy costs and environmental impacts. The heat exchangers transfer the heat of the high-temperature fluid to another low-temperature fluid. Using this temperature difference during transfer, energy, and power can also be obtained without using fuel. In the Stirling engine, the expansion of the volume of high-temperature gas is achieved by taking advantage of the narrowing of the volume of low-temperature gas, but its efficiency is quite low and an external heat source is needed. Therefore, methods that increase the overall efficiency of the system are studied as the heat of the high temperature fluid will be utilized through the heat exchanger without the need for any external heat and energy source.

DETAILED DESCRIPTION OF THE INVENTION

In this detailed description, the subject of the invention is explained without any restriction and only with reference to the examples to better explain the subject.

Figure 1 shows a schematic of a heat exchanger motor and an electronic control method according to the invention. Figure 2 illustrates a flowchart of the working arrangement in which the motor piston for a heat exchanger motor and the electronic control method according to the invention is located in the middle of the motor cylinder or close to the cold fluid line. Figure 3 is a flowchart of the working arrangement in a state in which the motor piston is close to the hot fluid line of a heat exchanger motor and the electronic control method of the invention. In the motor (10) of the invention, there is a 3-way cold fluid inlet control valve (12) in which the cold fluid (13) coming from a cold fluid inlet pipe (14) is introduced and the flow is controlled. A cold fluid line (15) through which the flow of cold fluid (13) from the cold fluid inlet control valve (12) is provided is connected to the valve (12). Herein is a 3-way cold fluid outlet control valve (16) in which the flow of the cold fluid (13) from the cold fluid line (15) is controlled and connected to a cold fluid outlet pipe (18). The cold fluid line (15) is also connected to a hot fluid line (24). The hot fluid line (24) is connected to a 3-way hot fluid inlet control valve (20) in which the flow of the hot fluid (21) is controlled and to a hot fluid inlet pipe (22) connected with the valve (20). Here, the hot fluid (21 ) comes through the hot fluid inlet pipe (22) and passes through the 3-way hot fluid inlet control valve (20). The hot fluid (21) coming from the hot fluid inlet control valve (20) comes through the fluid line (24) and reaches the 3-way hot fluid outlet control valve (26). And from there, it is discharged through a hot fluid outlet pipe (28). There is also a motor cylinder (30) in the motor (10) of the invention that contains gas and a motor piston (32). There is an adjustable crankshaft (36) in the motor cylinder (30), which turns the forward and backward movement of the motor piston (32). The connection between the crankshaft (36) and the motor piston (32) is provided with a motor rod (34). There is also an electronic control unit (38) in the motor (10), which is controlled in such a way that it provides fluid inlet and outlet from the hot and cold fluid inlet/outlet valves (12) (16) (20) (26) in the motor (10). In the motor (10) of the invention, the instantaneous position (46) (47) of the motor piston in operation, for example, the situation (46) in which the piston is in the middle of the cylinder or close to the cold fluid line, or the situation (47) in which the piston is close to the hot fluid line, that is, the motor piston position detection (44) is performed with the electronic control unit (38). According to the detection made here, the direction of the cold fluid (13) in the 3-way cold fluid inlet control valve (12) can be determined. The outlet direction of the cold fluid (13) in the 3-way cold fluid outlet control valve (16) can also be determined. For the hot fluid (21 ), the direction in the 3-way hot fluid inlet control valve (20) and the outlet direction of the hot fluid (21 ) in the 3-way cold fluid outlet control valve (26) can also be determined. In the invention, the heat exchanger motor (10) was obtained by transferring heat from the surface areas where the cylinder (30) contacts the fluid lines (15) (24). In the motor cylinder (30), the gas volume can be reduced due to the reduction of the temperature of the gas with the cold fluid (13), and the gas volume is increased due to the increase of the temperature of the gas with the hot fluid (21 ) in the motor cylinder (30).

In the electronically controlled method of the heat exchanger motor of the invention, first of all, the cold fluid (13) reaches the 3-way inlet control valve (42) by passing through the cold fluid inlet pipe (40). The electronic control unit (38) then detects the instantaneous position (46) (47) of the motor piston and sends the fluid (13) from the cold fluid line (50) or hot fluid line (62). Here, when the electronic control unit (38) performs a condition detection (44) in the middle of the motor cylinder or close to the cold fluid line, the following steps take place respectively;

• The cold fluid (13) reaches the hot fluid line (48) through the cold fluid inlet control valve (42),

• The cold fluid (13) passes through the hot fluid line (50) and reaches the cold fluid outlet control valve (52),

• Approximately, the fluid (13) reaches and exits the cold fluid outlet pipe (54) from the cold fluid outlet control valve (52),

• The hot fluid (21 ) reaches the cold fluid line (60) through the hot fluid inlet pipe (56) and the hot fluid inlet control valve (58),

• The hot fluid (21) reaches the hot fluid outlet control valve (64) through the cold fluid line (62),

• Approximately, the fluid (21) reaches and exits the hot fluid outlet pipe (66) from the hot fluid outlet control valve (64).

When the electronic control unit (38) performs a condition detection (44) in which the piston is close to the hot fluid line, the following steps take place respectively;

• The cold fluid (13) reaches the cold fluid line (60) through the cold fluid inlet control valve (42),

• The cold fluid (13) reaches the cold fluid outlet control valve (52) by passing through the cold fluid line (62),

• Approximately, the fluid reaches and exits the cold fluid outlet pipe (54) from the cold fluid outlet control valve (52),

• The hot fluid (21) reaches the hot fluid line (48) through the hot fluid inlet pipe (56) and the hot fluid inlet control valve (58),

• Hot fluid (21), passing through the hot fluid line (50), reaching the hot fluid outlet control valve (64),

• Approximately it reaches and exits the hot fluid outlet pipe (66) from the hot fluid outlet control valve (64).

In addition, the motor piston (32) of the heat exchanger motor (10) divides the motor cylinder (30) into two as high temperature and low temperature regions. High-temperature gas occupies more volume at the same pressure, while low-temperature gas occupies less volume at the same pressure. Due to the temperature difference, the piston (32) is moving. The mechanical movement of the piston (32) is transmitted to the crankshaft (36) by the motor rod (34). Thus, the back and forth movement of the piston (32) turns into a rotational movement in the crankshaft (36).
