Abstract

PURPOSE:To stably convert thermal energy into dynamic energy in high thermal efficiency by using an amorphous magnetic material as a magnetic material. CONSTITUTION:A rotatably or linearly moving magnetic engine is formed of the arraying shape of magnetic material 1 plates. If the material 1 is thick, the surface temperature and the interior temperature are different, and its thermal efficiency is lowered. If the material 1 is formed in a continuous shape, a quantitative temperature difference is scarcely imparted to the material 1 in a magnetic field, and its thermal efficiency is reduced. As a method of solving a decrease in the thermal efficiency, in addition to a method of forming the amorphous material in a thin plate shape, connecting them at a suitable interval and bending it in a wavy plate shape, a method of forming grooves at a suitable interval and opening holes, a method of forming an inner cavity, there are various methods such as a method of forming a lattice structure or a honeycomb structure.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a magnetic engine that converts thermal energy into mechanical energy using magnetic force.

(Prior art) Ferromagnetic materials have traditionally been used as magnetic materials in magnetic engines that convert thermal energy into mechanical energy by utilizing the property that the magnetic permeability and magnetic susceptibility of magnetic materials change with temperature. The magnetic permeability and magnetic susceptibility of ferromagnetic materials, which had previously been used, show an exponential decreasing characteristic as the temperature rises, so the temperature difference between high and low temperature regions becomes large, and the conversion efficiency of thermal energy is low. Ta.

(Problems to be Solved by the Invention) The present invention solves the above problems and has extremely high thermal efficiency.
The purpose of this invention is to provide a magnetic engine that stably converts thermal energy into mechanical energy.

(Means for solving the problem) In a magnetic engine that converts thermal energy into mechanical energy by utilizing the property that the magnetic permeability and magnetic susceptibility of magnetic materials change depending on temperature, amorphous (amorphous) is used as the magnetic material. ) A magnetic engine characterized by the use of magnetic materials.

(Function) The magnetic engines currently being devised can be broadly classified as follows.

1. Create a magnetic field with a magnetic field applying means, pass a magnetic material (continuous shape or a shape of magnetic material pieces connected at appropriate intervals) through this magnetic field, and apply heating means or cooling means to the magnetic material in the magnetic field. is used to provide a temperature difference region between a high temperature region and a low temperature region according to the Curie temperature of the magnetic material, and move the magnetic material or the magnetic field applying means.

2. Create a magnetic field with a magnetic field applying means, pass a magnet through this magnetic field with a means of shielding it with a magnetic material, and heat the magnetic material in the magnetic field using a heating means or a cooling means. Provides a temperature difference range between high temperature range and low temperature range according to Curie temperature.

Move the magnet side or the magnetic field applying means side.

3 The magnets are arranged with polarities that generate magnetic repulsion, and furthermore, a means is taken to shield the magnets with magnetic material between the magnets,
The magnetic material is heated to an arbitrary temperature or higher based on the Curie temperature of the material and cooled to an arbitrary temperature or lower using a heating means or a cooling means, and the magnet is moved (face-to-face movement or lateral movement).

There are the above three types of methods.

The magnetic permeability and magnetic susceptibility of ferromagnetic materials such as N, F, and C0 and their compounds generally decrease as the temperature increases, based on the Curie-Weiss law, resulting in an exponential decrease. Show characteristics.

On the other hand, the magnetic permeability and magnetic susceptibility of amorphous magnetic materials rapidly decrease near the Curie temperature unique to the material, and furthermore, compared to general ferromagnetic materials,
It has excellent properties such as dramatically high magnetic permeability, magnetic susceptibility, and thermal conductivity.

In the present invention, amorphous (am o
r p h o u s ) Since a magnetic material is used, the temperature difference between the high temperature region and the low temperature region near the Curie temperature, which is necessary to convert thermal energy into mechanical energy, is small, and the high magnetic permeability makes it highly magnetic. Since the material can be made thinner and has high thermal conductivity, it is possible to create a magnetic engine with extremely high thermal efficiency.

(Example) In Figure 1, a magnetic field is created using a magnetic field applying means (2).

In this magnetic field, the magnetic material (1) plates are passed in series at appropriate intervals, and the magnetic material (1) plates in the magnetic field are heated using the heating means (3) or the cooling means (4). FIG. 2 is a configuration diagram of an embodiment of a magnetic material engine that provides a temperature difference region between a high temperature region and a low temperature region according to the Curie temperature and moves a magnetic material (1) plate or a magnetic field application means (2).

Depending on the arrangement shape of the magnetic material (1) plates, a magnetic material engine capable of rotational movement or linear movement can be created.

When the magnetic material (1) is thick, its surface temperature and internal temperature are different, resulting in a decrease in thermal efficiency.

Furthermore, when the magnetic material (1) has a continuous shape, it is difficult to impart a quantitative temperature difference to the magnetic material (1) in a magnetic field, resulting in a decrease in thermal efficiency.

As a method to solve these problems, as shown in Figure 1,
There are two methods: making amorphous magnetic material into a thin plate shape and arranging them at appropriate intervals, or bending them into a corrugated shape, or creating grooves or holes at appropriate intervals as shown in Figure 2, or drilling holes at appropriate intervals as shown in Figure 3. In addition to the method of creating an internal hollow body, there are various solutions such as creating a lattice structure or a honeycomb structure.

Amorphous magnetic materials are still under development, and there is a possibility that materials with even better magnetic properties will be developed in the future.

If a device with a Curie temperature close to room temperature is developed, natural energy such as solar heat, geothermal heat, ocean temperature difference, etc., or waste heat from various heat engines can be effectively used as heating means (3).

Furthermore, if a device with a Curie temperature below room temperature is developed, the cooling energy of nature such as spirits and ice can be effectively utilized as the cooling means (4).

In particular, when a low-temperature liquefied gas such as liquid nitrogen is used as the cooling means (4), a completely pollution-free heat engine system can be constructed using both cold energy and physical energy of volumetric expansion.
