More specifically, the present invention is applicable to places with poor heat sources,
The present invention relates to magnetic fluid heat engines useful as heat pumps, coolers, etc. in spacecraft, deep-sea vessels, and the like.

Prior Art The concept of a magnetic fluid heat engine was proposed by Rozenswijk et al. in 1964, and it was subsequently experimentally confirmed that magnetic fluid actually moves. The magnetic fluid heat engine has a magnetic fluid 1 as shown in FIG.
A cooling device 7 and a heating device 8 are provided in the closed circuit of the pipe 3 through which the magnetic fluid 1 flows, and different The magnetic field device was arranged with magnetic poles facing each other.

ここで、磁性流体熱機関の動作原理を第3図に
基づいて説明すると、以下の通りである。
Here, the operating principle of the magnetic fluid heat engine will be explained based on FIG. 3 as follows.

That is, as shown in FIG. 3, the magnitude M of magnetization of the magnetic fluid 1 generally depends on the temperature T, and decreases as the temperature increases. The state of this change varies depending on the type of magnetic fluid 1, for example, Mn
-Magnetic fluid 1 composed of Zn ferrite particles
shows a remarkable change at a temperature that is not too high, around 100°C. When a magnetic field H is applied to the magnetic fluid 1, a force that attracts the magnetic fluid 1 by the magnetic field acts on the magnetic fluid 1, and the pressure P as the force that attracts the magnetic fluid 1 to the magnetic field H is as shown in the following equation. , is proportional to the magnetization magnitude M.

P=H OMdH That is, the magnetic fluid 1 with a low temperature and a large magnetization M is strongly drawn into the magnetic field, while the magnetic fluid 1 with a high temperature and a small magnetization is weakly drawn into the magnetic field. There will therefore be a net pressure difference between the magnetic fluid 1 in the left part of the magnetic field and the magnetic fluid 1 in the right part, as shown in FIG. Due to this pressure difference, the magnetic fluid 1 moves across the magnetic field from the low temperature side to the high temperature side. At this time, heating the magnetic fluid in the absence of a magnetic field, applying a magnetic field to the magnetic fluid isothermally,
The key is to cyclically repeat the four processes of heating the magnetic fluid in a magnetic field and isothermally separating the heated magnetic fluid from the magnetic field, that is, demagnetizing it. Additionally, in the process of the magnetic fluid 1 entering the magnetic field, the magnetic fluid 1 generates heat, and the cooling device 7 removes this heat. Further, in the process of demagnetizing the heated magnetic fluid 1, the magnetic fluid 1 absorbs heat. The heat is supplied from a heating device 8. This heat balance is the source of the kinetic energy of the magnetic fluid 1, which is why this device is called a heat engine, like an internal combustion engine or a steam turbine. The process corresponds to the piston-cylinder compression process, and the process corresponds to the piston-cylinder expansion process. Needless to say, the process is now an explosion process. However, the difference is that in the former engine, the working substance is gas, and in this device, the working substance is magnetic fluid 1.

Analyzing and studying the operation of such a magnetic fluid heat engine reveals that the conventional device shown in FIG. 3 is extremely unreasonable.

That is, in the case of this conventional device, the flow of the magnetic fluid 1 in the pipe 3 is slow, and even if a driving force extraction device such as a turbine is placed in the middle of the closed circuit of the pipe 3, the flow of the magnetic fluid 1 in the pipe 3 is slow. It was not possible to cause rotational motion in the system and extract it as kinetic energy outside the system.

The object of the present invention is to provide a magnetic fluid heat engine that can generate heat.

Composition of the Invention As a result of intensive research to achieve the above object, the present inventors have found that the flow velocity of the magnetic fluid in the pipe depends on the direction of the magnetic field applied to the magnetic fluid, and the direction of the applied magnetic field depends on the direction of the magnetic fluid. When it becomes the same as the direction of the flow,
It has been found that by keeping this direction the same and increasing the flow velocity, it is possible to generate rotational motion of the turbine. That is, as shown in FIG. 4a, in the case of a conventional heat engine, there is a gap between the cooling device 7 and the heating device 8, with respect to the pipe 3 through which the magnetic fluid 1 flows. Since different magnetic poles are arranged through the pipe 3 so that orthogonal magnetic fields are formed, the magnetic fluid 1
Since the magnetic particles 10 constituting the fluid are aligned in the direction of the magnetic field and perpendicular to the flow direction of the fluid, this state exhibits a plugging effect on the flow and increases the flow resistance.

On the other hand, when the magnetic field direction is the same as the flow direction as shown in FIG. 4b, the magnetic particles 10 are arranged in the flow direction, so the flow resistance of the magnetic fluid 1 hardly increases. Therefore, it is possible to extract the kinetic energy of the magnetic fluid through the heating/cooling cycle without being restricted by flow resistance.

That is, as illustrated in FIG. 1, the present invention includes a magnetic fluid 1 as a working substance to be filled, a pipe 3, a cooling device 7, a heating device 8, a driving force extraction device 4, and a magnetic field device. 5, the magnetic field device 5 is arranged between the cooling device 7 and the heating device 8, different magnetic poles (N, S) are arranged parallel to the pipe 3, A magnetic fluid heat engine is provided which forms a magnetic field in a direction parallel to or close to the flow direction of a magnetic fluid 1.

To explain in more detail, first, the pipe 3 is filled with the magnetic fluid 1 to form a loop so as to form a hollow part 2. Then, at a required position of this loop, a magnetic fluid 1 is attached to the pipe 3.
A cooling device 7 and a heating device 8 are arranged for heating and cooling.

The locations of the cooling device 7 and heating device 8 are as follows:
A magnetic field device 5 is arranged. At this time, the direction of the magnetic field is
The direction of flow is the same as that of the magnetic fluid 1. By doing so, the magnetic fluid 1 flows from the low temperature side to the high temperature side in the pipe 3, as indicated by the arrow in the figure. The force generated by this flow rotates a turbine, which is the driving force extraction device 4, and is extracted as kinetic energy.

To further explain the positional relationship between the cooling device 7, the heating device 8, and the magnetic field device 5, in the conventional device (FIG. 3), the cooling device 7 and the heating device 8 are placed outside the magnetic field device 5; is unreasonable, and as mentioned above, in this arrangement, only the weak magnetic field leaked to the outside of the magnetic field device 5 effectively contributes to energy conversion. On the other hand, in the method of applying a magnetic field parallel to the pipe 3 as in the present invention, the magnetic field is strongest at the center of both magnetic fields. The downstream part (right side in the figure) was heated. The cooling device 7 and the heating device 8 were arranged so that a low-temperature cooling region and a high-temperature heating region were formed in this magnetic field. By doing this, the magnetic field device 5
The maximum magnetic field generated can be effectively used for the movement of the magnetic fluid 1. Furthermore, in the air space between the two magnetic poles, a wider space is provided in the direction perpendicular to the pipe than in the conventional device, so that it is possible to incorporate the cooling device 7 and the heating device 8 inside the magnetic field device 5.

In addition, regarding the arrangement of the magnets constituting the magnetic field device 5 in the case of the example shown in FIG. 1, it is sufficient that the magnetic field is in the same direction as the flow of the magnetic fluid 1, for example, as illustrated in FIG. 2 a. A magnetic field device 5 having a hole through which the pipe 3 can pass is placed around the pipe 3 so that the N and S poles of the magnets face each other through the pipe 3, and a cooling device 7 is installed.
A heating device 8 may be placed in the hole via a heat insulating tube 6.

In the example shown in FIG. 2a, the diameter of the pipe 3 in the region heated by the heating device 8 is made smaller than the diameter in the region cooled by the cooling device 7. By doing so, even if the viscous resistance of the magnetic fluid 1 increases in a low temperature range, the flow velocity of the magnetic fluid 1 within the loop of the pipe 3 can be effectively made uniform.

もちろん、このようなパイプ3の径の変更は、
本発明にとつては必ずしも必要ではない。
Of course, such a change in the diameter of pipe 3,
This is not necessary for the present invention.

In addition, in the above example, the driving force extraction device 4
The turbine rotates due to the flow of the magnetic fluid 1 and converts the kinetic energy of the magnetic fluid 1 into rotational kinetic energy. Rotating is not always easy. Therefore, in the present invention, it is also effective to provide a cavity 2 above the fluid circuit of the magnetic fluid 1, as shown in FIGS. 1 and 2. When the heat engine is stopped, this air space 2 remains at the same level above the circuit, but when the engine starts operating, the liquid level of the magnetic fluid on the right side of the circuit begins to rise.
The magnetic fluid 1 circulates further and is filled up to the upper part of the turbine 4 (turbine inlet). On the other hand, the liquid level of the magnetic fluid 1 on the left side of the circuit is lowered, and the turbine is exposed to the gas. That is, the empty space 2 moves to the turbine 4 area while maintaining the same volume. In this way, the turbine is able to rotate at high speeds. In the sky part 2,
Inert gas etc. can be sealed.

Made of low carbon material. The width of the opposing gap between the different magnetic poles where the magnetic field is generated was 50 mm. A hole with a diameter of 25 mm is drilled through this magnet, and the pipe 3 is inserted into this hole.

Effects of the Invention According to the magnetic fluid heat engine of the present invention, since the direction of the magnetic fluid flow and the direction of the magnetic field are parallel, the fine particles of the magnetic fluid are aligned in the direction of the magnetic fluid flow, and are perpendicular to the flow direction. The flow resistance is significantly reduced compared to the case of conventional devices with magnetic fields applied. In addition, the demagnetizing field of the magnetic fluid generated by applying a magnetic field becomes smaller, and as a result, the effective magnetic field applied to the magnetic fluid increases, which contributes to further increasing the flow speed of the magnetic fluid in the pipe. However, it is also possible to give rotational motion to a turbine placed in the middle of the pipe and extract kinetic energy outside the system.
