Description

本発明は、印加される磁界の変化によって温度変化する磁性体を用いた温度調整装置および温度調整システムに関する。   The present invention relates to a temperature adjustment device and a temperature adjustment system using a magnetic material that changes in temperature according to a change in an applied magnetic field.

従来、冷蔵庫、冷凍庫やエアコン等の温度調整装置では、気体の圧縮および膨張による温度変化を利用した温度調整技術が用いられている。このような温度調整装置では、気体を圧縮するための圧縮機等が必要であり、効率の向上や小型化には限界がある。また、フロンガス等の環境破壊物質の排出が問題となっている。   2. Description of the Related Art Conventionally, in a temperature adjusting device such as a refrigerator, a freezer, or an air conditioner, a temperature adjusting technique using a temperature change due to gas compression and expansion is used. Such a temperature control device requires a compressor or the like for compressing gas, and there is a limit to improvement in efficiency and miniaturization. In addition, the discharge of environmentally destructive substances such as chlorofluorocarbon gas is a problem.

これらの問題を解決する一つの手段として、近年、印加する磁界の変化に伴い温度変化をする磁性体（以下、「磁気作業物質」と称す。）を用いた磁気温度調整技術が用いられている。この磁気作業物質は、磁気作業物質に印加する磁界を強めると磁気作業物質の温度が上昇し、磁気作業物質に印加する磁界を弱めると磁気作業物質の温度が低下する。この磁気作業物質が充填された領域に熱伝達媒体を流し、磁気作業物質の温度変化を熱伝達媒体に伝える。その熱伝達媒体をポンプにより熱交換器へ流すことで、磁気作業物質の温度変化を熱交換器へ伝達する。圧縮および膨張によって温度が変化する気体に代えて、このような、印加される磁界の変化によって温度が変化する磁気作業物質を用いることにより、効率の向上および小型化が可能となり、かつ環境破壊物質を排出しない温度調整装置が提供されている（例えば特許文献１参照）。   As a means for solving these problems, a magnetic temperature adjustment technique using a magnetic material (hereinafter referred to as “magnetic working substance”) that changes in temperature with changes in an applied magnetic field has been used in recent years. . When the magnetic field applied to the magnetic working material is increased, the temperature of the magnetic working material increases, and when the magnetic field applied to the magnetic working material is weakened, the temperature of the magnetic working material decreases. A heat transfer medium is caused to flow through the region filled with the magnetic working material, and a temperature change of the magnetic working material is transmitted to the heat transfer medium. By flowing the heat transfer medium to the heat exchanger by a pump, the temperature change of the magnetic working material is transmitted to the heat exchanger. By using a magnetic working material whose temperature changes due to a change in the applied magnetic field, instead of a gas whose temperature changes due to compression and expansion, the efficiency can be improved and the size can be reduced. There is provided a temperature control device that does not discharge (see, for example, Patent Document 1).

特許文献１に記載された技術思想によれば、磁気作業物質と巻線と永久磁石を並列に配置し、それぞれを磁性体のヨークにより接続している。巻線に電流を流すことにより磁界が発生し、永久磁石の磁界の向きと同方向に磁界を発生させたときが磁気作業物質へ磁場を印加している状態となり、永久磁石の磁界の向きと逆方向に磁界を発生させたときが磁気作業物質へ磁場を印加していない状態となる。この巻線に流す電流の向きを変えることにより、磁気作業物質への磁場の印加・除去を繰り返す。磁場の印加・除去の際生じる温熱・冷熱をポンプで熱輸送して、温熱と冷熱に分離する構成である。 According to the technical idea described in Patent Document 1, a magnetic working substance, a winding, and a permanent magnet are arranged in parallel, and are connected by a magnetic yoke. When a current is passed through the winding, a magnetic field is generated, and when a magnetic field is generated in the same direction as the direction of the magnetic field of the permanent magnet, the magnetic field is applied to the magnetic work substance. When the magnetic field is generated in the reverse direction, the magnetic field is not applied to the magnetic working substance. By changing the direction of the current flowing through the winding, the magnetic field is repeatedly applied and removed from the magnetic working material. This is a configuration in which hot / cold heat generated during application / removal of a magnetic field is transported by a pump and separated into hot / cold heat.

特開２００４−３１７０４０号公報JP 2004-317040 A

しかしながら、上記の構成では、永久磁石から発生する磁場を磁気作業物質へ通過させている間、巻線に大電流を流し続ける必要があるため、消費電力が大きく、また巻線に大電流を流し続けることで生じる発熱により、磁気作業物質に熱影響を与えてしまう問題がある。   However, in the above configuration, since it is necessary to keep a large current flowing through the winding while the magnetic field generated from the permanent magnet is passed to the magnetic working material, power consumption is large and a large current is passed through the winding. There is a problem in that the heat generated by continuing continues to affect the magnetic working material.

本発明は上記事情に鑑みてなされたものであり、磁気作業物質への磁場の印加・除去を容易に行うことでき、また消費電力を低減することができる構造の磁気温度調節装置を提供することにある。   The present invention has been made in view of the above circumstances, and provides a magnetic temperature control device having a structure capable of easily applying and removing a magnetic field to a magnetic working substance and reducing power consumption. It is in.

上記目的を達成するため、請求項１記載の磁気温度調節装置は、永久磁石と、印加磁界の変化により温度変化する磁性体である磁気作業物質を内部に充填した熱発生室と、前記永久磁石の一方の極と前記熱発生室とを磁気的に接続する磁性体で形成された第１磁性体コアと、前記永久磁石の他方の極と前記熱発生室とを磁気的に接続する磁性体で形成された第２磁性体コアと、前記第１磁性体コアと前記第２磁性体コアの間に配置され、前記第１磁性体コアと前記第２磁性体コアとを磁気的に接触した状態と、非接触の状態とを移動機構を介して切り替える可動磁性体コアと、を有することを特徴とする。   In order to achieve the above object, a magnetic temperature control apparatus according to claim 1 is a permanent magnet, a heat generation chamber filled with a magnetic working material that is a magnetic body that changes in temperature according to a change in applied magnetic field, and the permanent magnet. A first magnetic core formed of a magnetic body that magnetically connects one of the poles and the heat generation chamber; and a magnetic body that magnetically connects the other pole of the permanent magnet and the heat generation chamber. The second magnetic core formed in the above, and the magnetic core is disposed between the first magnetic core and the second magnetic core, and the first magnetic core and the second magnetic core are in magnetic contact with each other And a movable magnetic core that switches between a state and a non-contact state via a movement mechanism.

本発明によれば、磁気作業物質への磁場の印加・除去を容易に行うことでき、また消費電力を低減することができる。   According to the present invention, a magnetic field can be easily applied to and removed from a magnetic working substance, and power consumption can be reduced.

以下、本発明の実施の形態について、図１ないし図１０を参照しながら説明する。   Hereinafter, embodiments of the present invention will be described with reference to FIGS.

以下、本発明を温度調整装置１に適用した実施例１について、図１または図２を参照しながら説明する。図１は、温度調整装置１の斜視図を示している。図２は、温度調整装置１のＡ−Ａ断面図を示している。温度調整装置１は、コの字状に形成された第１磁性体コア２と第２磁性体コア３と、第１磁性体コア２と第２磁性体コア３の一方に挟まれて配置された永久磁石４と、第１磁性体コア２と第２磁性体コア３の他方に挟まれて配置された熱交換器５と、永久磁石４と熱交換器５との間に配置された可動磁性体コア６と、熱交換器５および可動磁性体コア６に電気的に接続された制御装置１００とから構成されている。   Hereinafter, a first embodiment in which the present invention is applied to a temperature control apparatus 1 will be described with reference to FIG. 1 or FIG. FIG. 1 shows a perspective view of the temperature adjusting device 1. FIG. 2 shows an AA cross-sectional view of the temperature control device 1. The temperature adjusting device 1 is disposed between a first magnetic core 2 and a second magnetic core 3 formed in a U-shape, and one of the first magnetic core 2 and the second magnetic core 3. The permanent magnet 4, the heat exchanger 5 disposed between the other of the first magnetic core 2 and the second magnetic core 3, and the movable disposed between the permanent magnet 4 and the heat exchanger 5. The magnetic core 6 includes a heat exchanger 5 and a control device 100 electrically connected to the movable magnetic core 6.

第１磁性体コア２および第２磁性体コア３は、鉄、フェライトコア等の磁性体で形成されている。第１磁性体コア２と第２磁性体コア３は、同形状で、コの字状に形成されており、線対称に対向して配置されている。また、第１磁性体コア２および第２磁性体コア３は、それぞれ中央部に円形の穴が形成されている。   The 1st magnetic body core 2 and the 2nd magnetic body core 3 are formed with magnetic bodies, such as iron and a ferrite core. The 1st magnetic body core 2 and the 2nd magnetic body core 3 are the same shape, are formed in U shape, and are arrange | positioned facing line symmetry. The first magnetic core 2 and the second magnetic core 3 each have a circular hole at the center.

永久磁石４は、例えばネオジム焼結磁石などで形成され、コの字状に形成された第１磁性体コア２の一端２ａと、その一端に対向する第２磁性体コア３の一端３ａとに挟まれた位置に接着剤などで固定されている。また、永久磁石４は、第１磁性体コア２の一端２ａおよび第２磁性体コア３の一端３ａと接する面方向に単極に磁化されており、例えば第１磁性体コア２と接触する側をＮ極とし、第２磁性体コア３と接触する側をＳ極としている。   The permanent magnet 4 is formed of, for example, a neodymium sintered magnet, and has one end 2a of the first magnetic core 2 formed in a U-shape and one end 3a of the second magnetic core 3 facing the one end. It is fixed to the sandwiched position with an adhesive. Further, the permanent magnet 4 is magnetized in a single pole in a surface direction in contact with the one end 2 a of the first magnetic core 2 and the one end 3 a of the second magnetic core 3, for example, the side in contact with the first magnetic core 2. Is the N pole, and the side in contact with the second magnetic core 3 is the S pole.

熱交換器５は、熱発生室７と、温熱部８と、冷熱部９と、ポンプ１０とが配管１１により接続されて構成されている。   The heat exchanger 5 is configured by connecting a heat generation chamber 7, a heating unit 8, a cooling unit 9, and a pump 10 through a pipe 11.

熱発生室７は、アクリル樹脂などの非磁性体の箱７ａと、箱７ａの内部に充填された粒子状の磁気作業物質７ｂとから構成されている。磁気作業物質７ｂは、例えばガドリニウム（Ｇｄ）強磁性体、もしくはランタン−鉄−シリコン（Ｌｅ−Ｆｅ−Ｓｉ）系などの磁性体を、例えば球状粒子、細粒子によって構成されている。これらの磁気作業物質７ｂは、上記磁性体に限られず、外部から磁界を加えると温度が上昇し、磁界を取り去るとその温度が下降するという磁気熱量効果を有する材料であれば良い。   The heat generation chamber 7 is composed of a box 7a made of a non-magnetic material such as acrylic resin, and a particulate magnetic working substance 7b filled in the box 7a. The magnetic working substance 7b is made of, for example, a gadolinium (Gd) ferromagnetic material or a magnetic material such as a lanthanum-iron-silicon (Le-Fe-Si) system, for example, spherical particles or fine particles. These magnetic working substances 7b are not limited to the above-described magnetic material, and may be any material having a magnetocaloric effect that increases in temperature when a magnetic field is applied from the outside and decreases when the magnetic field is removed.

温熱部８は、熱発生室７の一面から配管１１を介して接続されており、冷熱部９は、熱発生室７の一面に対向する裏面から配管１１を介して接続されている。温熱部８は温熱を排熱可能な熱回収部として機能し、冷熱部９は冷熱を蓄積または排気する熱回収部として機能する。ポンプ１０は、配管１１を介して温熱部８と接続されている。また、ポンプ１０は、制御装置１００と電気的に接続されている。熱発生室７、温熱部８、冷熱部９、ポンプ１０および配管１１の内部には、水や不凍液などの熱伝達媒体が充填されており、制御装置１００からの信号を受けてポンプ１０を作動することにより、熱伝達媒体が熱発生室７、温熱部８、冷熱部９の間を配管１１を介して流動可能な構成となっている。これにより、磁気作業物質７ｂで発生した温熱／冷熱が、熱伝達媒体を通じて温熱部８、冷熱部９にポンプ１０により輸送されることで熱交換可能に構成されている。   The heating unit 8 is connected from one surface of the heat generation chamber 7 through a pipe 11, and the cooling unit 9 is connected from the back surface facing the one surface of the heat generation chamber 7 through the piping 11. The heating unit 8 functions as a heat recovery unit that can exhaust the heat, and the cooling unit 9 functions as a heat recovery unit that accumulates or exhausts the cooling heat. The pump 10 is connected to the heating unit 8 via the pipe 11. The pump 10 is electrically connected to the control device 100. The heat generation chamber 7, the hot and cold section 8, the cold section 9, the pump 10, and the pipe 11 are filled with a heat transfer medium such as water or antifreeze, and the pump 10 is activated in response to a signal from the control device 100. By doing so, the heat transfer medium can flow between the heat generation chamber 7, the hot part 8, and the cold part 9 through the pipe 11. Thereby, the heat / cold heat generated in the magnetic working material 7b is transported by the pump 10 to the hot and cold parts 8 and 9 through the heat transfer medium so that heat exchange is possible.

可動磁性体コア６は、鉄やフェライトなどの磁性体で円柱状に形成され、永久磁石４と熱交換器５の間に配置されており、第１磁性体コア２および第２磁性体コア３の中央部に形成された円形の穴を通じて移動可能な構成となっている。可動磁性体コア６の一端には、リニアアクチュエータ（例えば、リニア誘導モータ、リニアパルスモータ、リニア直流モータ、リニア電磁ソレノイド）などで構成される移動機構１２が接続されている。移動機構１２は、制御装置１００と電気的に接続されており、制御装置１００の信号を受けて移動機構１２を作動させることにより、第１磁性体コア２と第２磁性体コア３を磁気的に接触・非接触とすることが可能となる。   The movable magnetic core 6 is formed in a cylindrical shape with a magnetic material such as iron or ferrite, and is disposed between the permanent magnet 4 and the heat exchanger 5. The first magnetic core 2 and the second magnetic core 3 are arranged. It is configured to be movable through a circular hole formed in the central portion of the. One end of the movable magnetic core 6 is connected to a moving mechanism 12 constituted by a linear actuator (for example, a linear induction motor, a linear pulse motor, a linear DC motor, a linear electromagnetic solenoid) or the like. The moving mechanism 12 is electrically connected to the control device 100, and operates the moving mechanism 12 in response to a signal from the control device 100, thereby magnetically connecting the first magnetic core 2 and the second magnetic core 3. It is possible to make contact or non-contact.

次に、上記構成の温度調整装置１の動作について説明する。   Next, the operation of the temperature control apparatus 1 having the above configuration will be described.

移動機構１２を動作させることにより、可動磁性体コア６が図２（ａ）に示すように第１磁性体コア２と第２磁性体コア３を磁気的に接続する。この状態においては、永久磁石４のＮ極から出た磁束は、第１磁性体コア２、可動磁性体コア６、第２磁性体コア３に至る磁路を経て、永久磁石４のＳ極に戻り、閉磁路Ｌ１を構成する。これは、非磁性体の箱７ａで形成された熱発生室７側は、閉磁路Ｌ１と比較して磁気抵抗が大きいため、磁束が通りにくくなることによる。この時、熱発生室７内の磁気作業物質７ｂには磁場が印加されていない状態となる。   By operating the moving mechanism 12, the movable magnetic core 6 magnetically connects the first magnetic core 2 and the second magnetic core 3 as shown in FIG. In this state, the magnetic flux emitted from the N pole of the permanent magnet 4 passes through the magnetic path to the first magnetic core 2, the movable magnetic core 6, and the second magnetic core 3, and reaches the S pole of the permanent magnet 4. Returning, the closed magnetic circuit L1 is configured. This is because the heat generation chamber 7 side formed by the non-magnetic box 7a has a larger magnetic resistance than the closed magnetic path L1, and therefore it is difficult for the magnetic flux to pass therethrough. At this time, a magnetic field is not applied to the magnetic working substance 7b in the heat generation chamber 7.

続いて、移動機構１２を動作させることにより、可動磁性体コア６を図２（ｂ）に示すように第１磁性体コア２と第２磁性体コア３を磁気的に非接続とするように移動する。この状態においては、永久磁石４のＮ極から出た磁束は、第１磁性体コア２、熱発生室７、第２磁性体コア３に至る磁路を経て、永久磁石４のＳ極に戻り、閉磁路Ｌ２を構成する。この時、ブロック内の磁気作業物質７ｂには磁場が印加されている状態となる。磁気作業物質７ｂに磁場が印加されると、磁気作業物質７ｂは、その粒子の格子系の電子スピンが磁場の方向にそろった状態になるため磁気エントロピーが小さくなり、エネルギーが格子系に与えられるようになり格子振動が激しくなり磁性体の温度を上昇することで温熱が発生する。   Subsequently, the moving mechanism 12 is operated so that the movable magnetic core 6 is magnetically disconnected from the first magnetic core 2 and the second magnetic core 3 as shown in FIG. Moving. In this state, the magnetic flux emitted from the N pole of the permanent magnet 4 returns to the S pole of the permanent magnet 4 through a magnetic path that reaches the first magnetic core 2, the heat generation chamber 7, and the second magnetic core 3. The closed magnetic circuit L2 is configured. At this time, a magnetic field is applied to the magnetic working substance 7b in the block. When a magnetic field is applied to the magnetic working material 7b, the magnetic working material 7b is in a state where the electron spins of the lattice system of the particles are aligned in the direction of the magnetic field, so that the magnetic entropy is reduced and energy is given to the lattice system. As a result, the lattice vibration becomes intense and the temperature of the magnetic material is raised, so that heat is generated.

その後、ポンプ１０を作動し、磁気作業物質７ｂに発生した温熱を、熱伝達媒体により配管１１を通じて温熱部８に輸送する。温熱を輸送後、ポンプ１０を停止する。   Thereafter, the pump 10 is operated, and the warm heat generated in the magnetic working material 7b is transported to the warm temperature section 8 through the pipe 11 by the heat transfer medium. After transporting warm heat, the pump 10 is stopped.

続いて、移動機構１２を動作させることにより、可動磁性体コア６を図２（ａ）に示すように第１磁性体コア２と第２磁性体コア３を磁気的に接続状態とする。この状態においては、上記したように、永久磁石４のＮ極から出た磁束は、第１磁性体コア２、可動磁性体コア６、第２磁性体コア３に至る磁路を経て、永久磁石４のＳ極に戻り、閉磁路Ｌ１を構成する。この時、先ほどまで磁場が印加されていた熱発生室７内の磁気作業物質７ｂの磁場が除去された状態となる。磁気作業物質７ｂから磁場が除去されると、磁気作業物質７ｂはその粒子の格子系の電子スピンがランダムな向きの状態をとり、磁気エントロピーが大きくなり、磁気作業物質７ｂは吸熱することで冷却される。   Subsequently, by operating the moving mechanism 12, the movable magnetic core 6 is brought into a magnetically connected state between the first magnetic core 2 and the second magnetic core 3 as shown in FIG. In this state, as described above, the magnetic flux emitted from the N pole of the permanent magnet 4 passes through the magnetic path to the first magnetic core 2, the movable magnetic core 6, and the second magnetic core 3, and the permanent magnet Returning to the 4th S pole, the closed magnetic circuit L1 is formed. At this time, the magnetic working substance 7b in the heat generating chamber 7 to which the magnetic field has been applied is removed. When the magnetic field is removed from the magnetic working material 7b, the magnetic working material 7b takes a state in which the electron spin of the lattice system of the particles is in a random direction, the magnetic entropy increases, and the magnetic working material 7b cools by absorbing heat. Is done.

その後、ポンプ１０を作動し、磁気作業物質７ｂに発生した冷熱を、熱伝達媒体により配管１１を通じて冷熱部９に輸送する。冷熱を輸送後、ポンプ１０を停止する。   Thereafter, the pump 10 is operated, and the cold heat generated in the magnetic working material 7b is transported to the cold heat section 9 through the pipe 11 by the heat transfer medium. After transporting the cold heat, the pump 10 is stopped.

このような温熱輸送／冷熱輸送の熱サイクルを所定時間（例えば約１秒程度）毎に繰り返すことで、温熱／冷熱を効率良く輸送することができる。   By repeating the heat cycle of such heat transport / cold heat transport every predetermined time (for example, about 1 second), the heat / cold heat can be efficiently transported.

本実施例によれば、可動磁性体コア６を移動させ、第１磁性体コア２と第２磁性体コア３との間を磁気的に接続／非接続とすることで、磁気作業物質７ｂへの磁界の印加および除去を容易に変化させることができ、さらに消費電力を低減することができる。   According to the present embodiment, the movable magnetic core 6 is moved, and the first magnetic core 2 and the second magnetic core 3 are magnetically connected / disconnected to the magnetic working material 7b. The application and removal of the magnetic field can be easily changed, and the power consumption can be reduced.

また、可動磁性体コア６を移動させる移動機構１２を磁気作業物質７ｂから遠ざけて構成することができるため、移動機構１２で発生した熱が磁気作業物質７ｂへ影響を与えることを妨げることができる。   Further, since the moving mechanism 12 for moving the movable magnetic core 6 can be configured away from the magnetic working material 7b, it is possible to prevent the heat generated by the moving mechanism 12 from affecting the magnetic working material 7b. .

図３は、本発明の実施例２を示すもので、前述の実施例１と異なるところは、第１磁性体コア２および第２磁性体コア３と、可動磁性体コア１３との接触部分にある。なお、実施例１と同一部分については同一符号を付して説明を省略し、異なる部分を中心に説明する。   FIG. 3 shows a second embodiment of the present invention. The difference from the first embodiment is that the first magnetic core 2 and the second magnetic core 3 are in contact with the movable magnetic core 13. is there. Note that the same portions as those in the first embodiment are denoted by the same reference numerals, description thereof is omitted, and different portions are mainly described.

可動磁性体コア１３は、その先端部が第１磁性体コア２より突出する様に形成され、突出した部分の比透磁率が先端に向かう程、小さくなるように構成されている。具体的には、最先端部１３ａから第１磁性体コア２に接触する部分１３ｂまでの比透磁率が７０００以下の鉄材で形成し、第１磁性体コア２に接触する部分１３ｃから第２磁性体コア３に接触する部分１３ｂまでの比透磁率が７０００程度の４％ケイ素鉄で形成することで、図４に示すように、可動磁性体コア１３の先端にいくに従い徐々に比透磁率を小さくするように構成されている。   The movable magnetic core 13 is formed so that the tip portion protrudes from the first magnetic core 2, and is configured such that the relative permeability of the protruded portion decreases toward the tip. Specifically, the relative magnetic permeability from the most advanced portion 13a to the portion 13b in contact with the first magnetic core 2 is made of an iron material having a relative magnetic permeability of 7000 or less, and the second magnetic from the portion 13c in contact with the first magnetic core 2 By forming 4% silicon iron having a relative permeability up to the portion 13b in contact with the body core 3 of about 7000, the relative permeability gradually increases toward the tip of the movable magnetic body core 13 as shown in FIG. It is configured to be small.

本実施例によれば、可動磁性体コア１３を移動させ、第１磁性体コア２と第２磁性体コア３との間を磁気的に接続／非接続とすることで、磁気作業物質７ｂへの磁界の印加および除去を容易に変化させることができ、さらに消費電力を低減することができる。   According to the present embodiment, the movable magnetic core 13 is moved, and the first magnetic core 2 and the second magnetic core 3 are magnetically connected / disconnected to the magnetic working substance 7b. The application and removal of the magnetic field can be easily changed, and the power consumption can be reduced.

また、可動磁性体コア１３の比透磁率を先端に向かう程小さくなるように構成することにより、可動磁性体コア１３を第１磁性体から引き抜くときに、第１磁性体コア２と可動磁性体コア１３の磁気吸引力を少しずつ低下させながら、可動磁性体コア１３を移動させることができる。これにより、可動磁性体コア１３を容易に移動させることができるので、移動機構１２の低出力化や低消費電力化を図ることができ、もって温度調整装置１全体の消費電力を低くすることができる。   Also, by configuring the relative magnetic permeability of the movable magnetic core 13 so as to decrease toward the tip, the first magnetic core 2 and the movable magnetic body are removed when the movable magnetic core 13 is pulled out from the first magnetic body. The movable magnetic core 13 can be moved while gradually decreasing the magnetic attractive force of the core 13. Thereby, since the movable magnetic core 13 can be easily moved, the output of the moving mechanism 12 can be reduced and the power consumption can be reduced, thereby reducing the power consumption of the entire temperature adjusting device 1. it can.

図４に示す本実施例の構成に限られず、図５に示すように段階的に比透磁率を変化させて構成しても同様の効果を得ることができる。   The configuration is not limited to the configuration of the present embodiment shown in FIG. 4, and the same effect can be obtained even when the relative permeability is changed stepwise as shown in FIG.

図６は、本発明の実施例３を示すもので、実施例１と異なるところは、第１磁性体コア２および第２磁性体コア３と、可動磁性体コア１４との接触部分にある。なお、実施例１と同一部分については同一符号を付して説明を省略し、異なる部分を中心に説明する。   FIG. 6 shows a third embodiment of the present invention. The difference from the first embodiment is in the contact portion between the first magnetic core 2 and the second magnetic core 3 and the movable magnetic core 14. Note that the same portions as those in the first embodiment are denoted by the same reference numerals, description thereof is omitted, and different portions are mainly described.

可動磁性体コア１４は、図６に示すように、その先端部が第１磁性体コア２の端面より突出する様に形成され、突出した部分１４ａが、先端に向かって細くなるように形成されている。本実施例では、先端テーパ角度を４５度としている。   As shown in FIG. 6, the movable magnetic core 14 is formed such that the tip thereof protrudes from the end surface of the first magnetic core 2, and the protruding portion 14 a is formed so as to become narrower toward the tip. ing. In this embodiment, the tip taper angle is 45 degrees.

本実施例によれば、実施例１と同様に、可動磁性体コア１４を移動させ、第１磁性体コア２と第２磁性体コア３との間を磁気的に接続／非接続とすることで、磁気作業物質７ｂへの磁界の印加および除去を容易に変化させることができる。   According to the present embodiment, similarly to the first embodiment, the movable magnetic core 14 is moved so that the first magnetic core 2 and the second magnetic core 3 are magnetically connected / disconnected. Thus, the application and removal of the magnetic field to the magnetic working material 7b can be easily changed.

また、本実施例によれば、さらに以下の効果を得ることができる。図７（ａ）〜（ｃ）は、可動磁性体コア１４が第１磁性体コア２から引き抜かれる過程を示している。第１磁性体コア２の表面と可動磁性体コア１４との距離が、第１磁性体コア２と可動磁性体コア１４との磁気吸引力に依存する。本実施例のように、可動磁性体コア１４の突出した部分が先端に向かって細くなるように形成することで、図７（ａ）〜（ｃ）に示すように第１磁性体コア２の表面と可動磁性体コア１４との距離が緩やかに広がっていく。このため、可動磁性体コア１４が引き抜かれる際の磁気吸引力を緩やかに低下させていくことが可能となる。これにより、可動磁性体コア１４を容易に移動させることができるので、移動機構１２の低出力化や低消費電力化を図ることができ、もって温度調整装置１全体の消費電力を低くすることができる。   Moreover, according to the present Example, the following effects can be acquired further. 7A to 7C show a process in which the movable magnetic core 14 is pulled out from the first magnetic core 2. The distance between the surface of the first magnetic core 2 and the movable magnetic core 14 depends on the magnetic attractive force between the first magnetic core 2 and the movable magnetic core 14. By forming the protruding part of the movable magnetic core 14 so as to become narrower toward the tip as in the present embodiment, the first magnetic core 2 of the first magnetic core 2 is formed as shown in FIGS. The distance between the surface and the movable magnetic core 14 gradually increases. For this reason, it becomes possible to gently reduce the magnetic attractive force when the movable magnetic core 14 is pulled out. Thereby, since the movable magnetic core 14 can be easily moved, the output of the moving mechanism 12 can be reduced and the power consumption can be reduced, thereby reducing the power consumption of the entire temperature adjusting device 1. it can.

本実施例の構成に限られず、可動磁性体コア１４の先端テーパ角度を別の値（例えば、３０度）として構成しても同様の効果を得ることができる。また、先端をテーパではなく、球面としても同様の効果を得ることができる。   The same effect can be obtained even when the tip taper angle of the movable magnetic core 14 is set to another value (for example, 30 degrees) without being limited to the configuration of the present embodiment. Further, the same effect can be obtained even when the tip is not a taper but a spherical surface.

図８は、本発明の実施例４を示すもので、実施例１と異なるところは、第１磁性体コア２および第２磁性体コア３と、可動磁性体コア１５との接触部分にある。なお、実施例１と同一部分については同一符号を付して説明を省略し、異なる部分を中心に説明する。   FIG. 8 shows a fourth embodiment of the present invention, which differs from the first embodiment in the contact portion between the first magnetic core 2 and the second magnetic core 3 and the movable magnetic core 15. Note that the same portions as those in the first embodiment are denoted by the same reference numerals, description thereof is omitted, and different portions are mainly described.

可動磁性体コア１５は、その外周にネジ溝が形成されており、また第１磁性体コア２および第２磁性体コア３の穴部にも同様にネジ溝が形成されている。   The movable magnetic core 15 has screw grooves formed on the outer periphery thereof, and also has screw grooves formed in holes of the first magnetic core 2 and the second magnetic core 3.

また、移動機構１２は、モータで形成し、回転部である軸１６にはウォームギア１７が固着されている。さらに、ウォームギア１７は可動磁性体コア１５のネジ溝にかみ合う様に移動機構１２が固定されている。   The moving mechanism 12 is formed of a motor, and a worm gear 17 is fixed to a shaft 16 that is a rotating portion. Further, the moving mechanism 12 is fixed to the worm gear 17 so as to engage with the thread groove of the movable magnetic core 15.

本実施例によれば、実施例１と同様に、可動磁性体コア１５を移動させ、第１磁性体コア２と第２磁性体コア３との間を磁気的に接触・非接触させることで、磁気作業物質７ｂへの磁界の印加および除去を容易に変化させることができる。   According to the present embodiment, similarly to the first embodiment, the movable magnetic core 15 is moved, and the first magnetic core 2 and the second magnetic core 3 are brought into magnetic contact / non-contact with each other. The application and removal of the magnetic field to the magnetic working substance 7b can be easily changed.

図９は、本発明の実施例５を示すもので、実施例１と異なるところは、可動磁性体コア１６の構成にある。なお、実施例１と同一部分については同一符号を付して説明を省略し、異なる部分を中心に説明する。   FIG. 9 shows a fifth embodiment of the present invention. The difference from the first embodiment is the configuration of the movable magnetic core 16. Note that the same portions as those in the first embodiment are denoted by the same reference numerals, description thereof is omitted, and different portions are mainly described.

可動磁性体コア１６は、鉄やフェライトなどの磁性体で、第１磁性体コア２の中央の突起部および第２磁性体コア３の中央部に挟持されている。また、可動磁性体コア１６の周囲には巻線１７が巻装されている。可動磁性体コア１６は、リニアアクチュエータ（例えば、リニア誘導モータ、リニアパルスモータ、リニア直流モータ、リニア電磁ソレノイド）などで構成される移動機構１２と移動ガイド１８により、移動ガイド１８に沿って、可動磁性体コア１６を第１磁性体コア２および第２磁性体コア３と接触する方向・非接触とする方向に移動する構成となっている。 The movable magnetic core 16 is a magnetic body such as iron or ferrite and is sandwiched between the central protrusion of the first magnetic core 2 and the central portion of the second magnetic core 3. A winding 17 is wound around the movable magnetic core 16. The movable magnetic core 16 is movable along the movement guide 18 by a movement mechanism 12 and a movement guide 18 constituted by a linear actuator (for example, a linear induction motor, a linear pulse motor, a linear DC motor, a linear electromagnetic solenoid). The magnetic core 16 is configured to move in a direction in which the magnetic core 16 is in contact with the first magnetic core 2 and the second magnetic core 3 or in a non-contact direction.

ここで、可動磁性体コア１６を第１磁性体コア２および第２磁性体コア３と接触状態から非接触状態にする際の可動磁性体コア１６の動作について説明する。   Here, the operation of the movable magnetic core 16 when the movable magnetic core 16 is brought into contact with the first magnetic core 2 and the second magnetic core 3 from the contact state to the non-contact state will be described.

可動磁性体コア１６は、第１磁性体コア２および第２磁性体コア３と接触しているときは、永久磁石４からの磁束により第１磁性体コア２および第２磁性体コア３側へ磁気吸引力が強く働いている。ここで、可動磁性体コア１６に巻装された巻線１７に電流を流し、永久磁石４からの磁束と反対の方向へ磁束を発生させる。これにより、可動磁性体コア１６内は、永久磁石４からの磁束と巻線１７による磁束とが拮抗した状態となる。このとき、第１磁性体コア２および第２磁性体コア３と可動磁性体コア１６との間の磁気吸引力はほぼゼロとなり、移動機構１２からの小さな力で可動磁性体コア１６を移動することができる。可動磁性体コア１６が第１磁性体コア２および第２磁性体コア３と非接触となったときに、巻線１７への電流を止める。   When the movable magnetic core 16 is in contact with the first magnetic core 2 and the second magnetic core 3, the first magnetic core 2 and the second magnetic core 3 are moved by the magnetic flux from the permanent magnet 4. Magnetic attraction is working strongly. Here, a current is passed through the winding 17 wound around the movable magnetic core 16 to generate a magnetic flux in a direction opposite to the magnetic flux from the permanent magnet 4. Thereby, the inside of the movable magnetic core 16 is in a state in which the magnetic flux from the permanent magnet 4 and the magnetic flux by the winding 17 are antagonized. At this time, the magnetic attractive force between the first magnetic core 2 and the second magnetic core 3 and the movable magnetic core 16 becomes substantially zero, and the movable magnetic core 16 is moved with a small force from the moving mechanism 12. be able to. When the movable magnetic core 16 is not in contact with the first magnetic core 2 and the second magnetic core 3, the current to the winding 17 is stopped.

一方、可動磁性体コア１６を第１磁性体コア２および第２磁性体コア３と非接触状態から接触状態にする際は、移動機構１２を動作し、可動磁性体コア１６を第１磁性体コア２および第２磁性体コア３に近づけることで、磁気吸引力が働き、容易に可動磁性体コア１６を移動させることができる。また、巻線１７に電流を流し、永久磁石４からの磁束と同じ方向へ磁束を発生させると、より大きな磁気吸引力が働き、容易に可動磁性体コア１６を移動させることができる。   On the other hand, when the movable magnetic core 16 is brought into contact with the first magnetic core 2 and the second magnetic core 3 from the non-contact state, the moving mechanism 12 is operated to move the movable magnetic core 16 to the first magnetic body. By moving closer to the core 2 and the second magnetic core 3, a magnetic attractive force works and the movable magnetic core 16 can be easily moved. Further, when a current is passed through the winding 17 to generate a magnetic flux in the same direction as the magnetic flux from the permanent magnet 4, a larger magnetic attraction force acts and the movable magnetic core 16 can be easily moved.

本実施例によれば、第１の実施例と同様に、可動磁性体コア１６を移動させ、第１磁性体コア２と第２磁性体コア３との間を磁気的に接続／非接続とすることで、磁気作業物質７ｂへの磁界の印加および除去を容易に変化させることができる。   According to the present embodiment, as in the first embodiment, the movable magnetic core 16 is moved, and the first magnetic core 2 and the second magnetic core 3 are magnetically connected / disconnected. By doing so, application and removal of the magnetic field to the magnetic working substance 7b can be easily changed.

また、可動磁性体コア１６に巻装された巻線１７に電流を流し、可動磁性体コア１６に磁束を発生させることで、第１磁性体コア２および第２磁性体コア３との間の磁気吸引力をほぼゼロに近づけることができる。これにより、可動磁性体コア１６を容易に移動させることができる。   Further, by passing a current through the winding 17 wound around the movable magnetic core 16 and generating a magnetic flux in the movable magnetic core 16, a gap between the first magnetic core 2 and the second magnetic core 3 is generated. The magnetic attractive force can be brought close to zero. Thereby, the movable magnetic core 16 can be easily moved.

また、可動磁性体コア１６を移動させるときのみ巻線１７に電流を流すので、温度調整装置１全体の消費電力を低くすることができる。 Further, since the current is passed through the winding 17 only when the movable magnetic core 16 is moved, the power consumption of the entire temperature adjusting device 1 can be reduced.

図１０は、実施例６示すもので、実施例５とは可動磁性体コア１６の移動機構に違いがある。なお、実施例５と同一部分については同一符号を付して説明を省略し、異なる部分を中心に説明する。   FIG. 10 shows the sixth embodiment, which is different from the fifth embodiment in the moving mechanism of the movable magnetic core 16. In addition, about the same part as Example 5, the same code | symbol is attached | subjected and description is abbreviate | omitted and it demonstrates centering on a different part.

可動磁性体コア１６は、鉄やフェライトなどの磁性体で、第１磁性体コア２の中央の突起部および第２磁性体コア３の中央部に挟持されている。また、可動磁性体コア１６の周囲には巻線１７が巻装されている。可動磁性体コア１６は、さらに、移動ガイド１９と、移動ガイド１８の先に配置された第２永久磁石１９とを備えている。なお、本実施例では、第１磁性体コア２の一端２ａおよび第２磁性体コア３の一端３ａに挟持された永久磁石を第１永久磁石４と称する。本実施例の第２永久磁石１９の磁化方向は、第１永久磁石４と逆方向とする。 The movable magnetic core 16 is a magnetic body such as iron or ferrite and is sandwiched between the central protrusion of the first magnetic core 2 and the central portion of the second magnetic core 3. A winding 17 is wound around the movable magnetic core 16. The movable magnetic core 16 further includes a movement guide 19 and a second permanent magnet 19 disposed at the tip of the movement guide 18. In the present embodiment, the permanent magnet sandwiched between the one end 2 a of the first magnetic core 2 and the one end 3 a of the second magnetic core 3 is referred to as a first permanent magnet 4. The magnetization direction of the second permanent magnet 19 in this embodiment is opposite to that of the first permanent magnet 4.

ここで、可動磁性体コア１６を第１磁性体コア２および第２磁性体コア３と接触状態から非接触状態にする際の可動磁性体コア６の動作について説明する。   Here, the operation of the movable magnetic core 6 when the movable magnetic core 16 is brought into a non-contact state with the first magnetic core 2 and the second magnetic core 3 will be described.

可動磁性体コア１６に巻装された巻線に電流を流し、第１永久磁石４からの磁束と反対の方向へ磁束を発生させる。これにより、可動磁性体コア１６内は、第１永久磁石４からの磁束と巻線１７による磁束とが拮抗した状態となる。このとき、第１磁性体コア２および第２磁性体コア３と可動磁性体コア１６との間の磁気吸引力はほぼゼロとなる。ここで、可動磁性体コア１６の磁化方向に対して、第２永久磁石１９の磁化方向は逆向きとなっているため、可動磁性体コア１６は、第２永久磁石１９に引き付けられる。この吸引力により移動ガイド１８に沿って可動磁性体コア６を移動させることができる。可動磁性体コア１６が第１磁性体コア２および第２磁性体コア３と非接触となったときに、巻線１７への電流を止める。   A current is passed through the winding wound around the movable magnetic core 16 to generate a magnetic flux in a direction opposite to the magnetic flux from the first permanent magnet 4. Thereby, the inside of the movable magnetic core 16 is in a state in which the magnetic flux from the first permanent magnet 4 and the magnetic flux by the winding 17 are antagonized. At this time, the magnetic attractive force between the first magnetic core 2 and the second magnetic core 3 and the movable magnetic core 16 is substantially zero. Here, since the magnetization direction of the second permanent magnet 19 is opposite to the magnetization direction of the movable magnetic core 16, the movable magnetic core 16 is attracted to the second permanent magnet 19. The movable magnetic core 6 can be moved along the movement guide 18 by this attractive force. When the movable magnetic core 16 is not in contact with the first magnetic core 2 and the second magnetic core 3, the current to the winding 17 is stopped.

逆に、可動磁性体コア１６を第１磁性体コア２および第２磁性体コア３と非接触状態から接触状態にする際の可動磁性体コア１６の動作について説明する。   Conversely, the operation of the movable magnetic core 16 when the movable magnetic core 16 is brought into contact with the first magnetic core 2 and the second magnetic core 3 from the non-contact state will be described.

可動磁性体コア１６に巻装された巻線１７に電流を流し、第２永久磁石１９の磁化方向と同方向に磁束を発生させる。これにより、可動磁性体コア１６は、第２永久磁石１９との間に反発力が働く。さらに、可動磁性体コア１６は、第１磁性体コア２および第２磁性体コア３との間に磁気吸引力が働く。この第２永久磁石１９との反発力および第１永久磁石４との磁気吸引力により、移動ガイドに沿って可動磁性体コア１６を移動させることができる。可動磁性体コア１６が第１磁性体コア２および第２磁性体コア３と接触状態となったときに巻線への電流を止める。   An electric current is passed through the winding 17 wound around the movable magnetic core 16 to generate a magnetic flux in the same direction as the magnetization direction of the second permanent magnet 19. Thereby, a repulsive force acts between the movable magnetic core 16 and the second permanent magnet 19. Further, the magnetic attractive force acts between the first magnetic core 2 and the second magnetic core 3 in the movable magnetic core 16. The movable magnetic core 16 can be moved along the movement guide by the repulsive force with the second permanent magnet 19 and the magnetic attraction force with the first permanent magnet 4. When the movable magnetic core 16 comes into contact with the first magnetic core 2 and the second magnetic core 3, the current to the winding is stopped.

本実施例によれば、実施例１と同様に、可動磁性体コア１６を移動させ、第１磁性体コア２と第２磁性体コア３との間を磁気的に接続／非接続とすることで、磁気作業物質７ｂへの磁界の印加および除去を容易に変化させることができる。   According to the present embodiment, similarly to the first embodiment, the movable magnetic core 16 is moved so that the first magnetic core 2 and the second magnetic core 3 are magnetically connected / disconnected. Thus, the application and removal of the magnetic field to the magnetic working material 7b can be easily changed.

また、可動磁性体コア６に巻装された巻線１７に電流を流し、可動磁性体コア１６に磁束を発生させることで、第２永久磁石４との吸引力・反発力を利用した可動磁性体コア１６の移動が可能となる。これにより、リニアアクチュエータなどの移動機構１２が不要となり、簡単な構成の磁気温度調整装置１を提供できる。さらに、移動機構１２が不要となることおよび可動磁性体コア１６の移動時のみ巻線１７に電流を流すことで、可動磁性体コア１６を移動するときの消費電力を低減することができる。   In addition, a current is passed through the winding 17 wound around the movable magnetic core 6 to generate a magnetic flux in the movable magnetic core 16, so that the movable magnetic utilizing the attractive force / repulsive force with the second permanent magnet 4 is used. The body core 16 can be moved. Thereby, the moving mechanism 12 such as a linear actuator is not necessary, and the magnetic temperature adjusting device 1 having a simple configuration can be provided. Furthermore, the power consumption when moving the movable magnetic core 16 can be reduced by causing the current to flow through the winding 17 only when the moving mechanism 12 becomes unnecessary and the movable magnetic core 16 is moved.

However, the first magnetic core 2 and the second magnetic core 3 are not limited to this shape. It may be disc-shaped or rod-shaped.

また、可動磁性体コアは、第１磁性体コア２と第２磁性体コア３を磁気的に接触状態と非接触状態を切り替えることができればよく、角柱等、種々の形状をとることができる。   Further, the movable magnetic core only needs to be able to magnetically switch the first magnetic core 2 and the second magnetic core 3 between a contact state and a non-contact state, and can take various shapes such as a prism.

また、上記実施例では、永久磁石４、可動磁性体コア、熱発生室７の順に配置することとしたが、この配置に限られず、例えば、永久磁石４、熱発生室７、可動磁性体コアの順でもよいし、熱発生室７、永久磁石４、可動磁性体コアの順でも同様の効果を得ることができる。   In the above embodiment, the permanent magnet 4, the movable magnetic core, and the heat generation chamber 7 are arranged in this order.
