くなつて圧力が低くなる。 The illustrated embodiment of the present invention has the above-mentioned configuration, and to explain the operation and effect, a magnetic fluid is a fluid such as oil or water with extremely fine ferromagnetic material suspended in it. Compared to ordinary fluids, it has extremely high magnetic permeability, and by placing it in a magnetic field, ferromagnetic substances suspended in the fluid are attracted and pressure is generated. The magnitude of the pressure P (Kgf/cm 2 ) is expressed as P=1/4π∫H 0J dH, where the magnetization strength is J (Gauss) and the magnetic field strength is H (Oe). Since a large magnetic field is applied by the magnet, the magnetization strength J of the magnetic fluid X is saturated and becomes a substantially constant value. Therefore, as shown in FIG. 5, when a magnetic field is applied to a container 14 with one side open and filled with magnetic fluid X so that lines of magnetic force S are generated,
Pressure is generated in the direction of magnetic flux, and the pressure is highest in the center, and as you move to the right, the magnetic flux density decreases and the pressure becomes lower.

力が発生する。 However, the fine magnetic material in the magnetic fluid
As shown in FIG. 6, it is known that the magnetic susceptibility decreases significantly where the temperature of the magnetic fluid is higher than the Curie point Te. Therefore, when the temperature of the magnetic fluid X is changed in the magnetic field, the values when the pressure increases and when the pressure decreases change. As shown in FIG. 5, the left and right pressure changes are not symmetrical, but as shown in FIG. 7. This is because when the temperature of the magnetic fluid exceeds the Curie point, the magnetic susceptibility of the magnetic material contained in the magnetic fluid decreases, and the magnetic properties of the magnetic fluid become significantly weaker, returning to a normal fluid. hand,
At this time, the characteristics of the magnetic fluid disappear and even if the magnetic flux density is high, it is not governed by the above equation and the pressure remains almost constant. Therefore, pressure is generated at the right end of the container 14 in FIG.

重ね合せられて高められる。 The above-mentioned magnetic fluid pressurization device uses the above-described principle, and can be a device that can obtain a large pressure and a large flow rate of the magnetic fluid.
A flow path 5 for flowing a high temperature heat medium Y from a high heat source is provided on the upper surface of the flow path 4 filled with the magnetic fluid X, and a flow path 6 for flowing a low temperature heat medium Z from a cold heat source is provided on the lower surface. Heating and cooling are repeated alternately according to the flow of the flow path 4, and the flow path 4 of the heating section 5a is heated and cooled repeatedly.
When a large magnetic field is applied to the part, as shown in Figure 8,
The temperature in the flow path 4 increases in the heating section 5a, and when the temperature reaches a certain point, the magnetic susceptibility of the magnetic fluid X decreases. As a result, the pressure increases almost to the center of the magnet, and then decreases slightly, but since the magnetic susceptibility has decreased, the amount of the decrease is small. By arranging a large number of magnets at appropriate intervals along the flow paths 4, 5, and 6, the pressures are superimposed and increased as shown in FIG.

うな温度分布となる。 Note that in FIG. 8, the direction in which the magnetic fluid X flows is indicated by an arrow, but since there is no initial velocity at the time of startup, it does not flow to the right or left. For this purpose, as shown in FIG. 9, by providing a flow path for the high-temperature heating medium Y only in a part of the wake side of each of the multiple stages of magnets, the magnetic field of the magnet is reduced as shown in FIG. It is possible to create a temperature gradient within and obtain an initial velocity. Once the magnetic fluid has a velocity, there is a time delay in the temperature rise of the magnetic fluid during heating, resulting in a temperature distribution as shown in FIG.

模の昇圧装置とすることができる。 According to the experimental results, a pressure difference of 0.1 to 0.2 Kgf/cm 2 per stage was obtained by heating to 100 to 160 °C using a magnetic fluid with a saturation magnetic flux density of 300 Gauss in a magnetic field of 5000 Gauss, and a pressure difference of 0.1 to 0.2 Kgf/cm 2 was obtained per stage. By combining several tens of stages of magnets, it is possible to create a practical pressure booster. In addition, it is not a good idea to make the magnets too large because the magnetic resistance will increase.
By forming a row or a set of several hundred rows, a practical scale booster can be obtained.
