Description

本考案はU字型磁性コアによる電磁誘導加熱式ラジエーターに関する。  The present invention relates to an electromagnetic induction heating radiator using a U-shaped magnetic core.

従来の暖房用等のラジエーターとしてはスチームラジエーターや電熱ラジエーターなどが知られている。また、E字型磁性コアを用いる電磁誘導式発熱器には鉄道レールの融雪装置(例えば、特許文献1参照)や電磁誘導型発熱器(例えば、特許文献2参照)がある。  As a conventional radiator for heating or the like, a steam radiator, an electric heat radiator, or the like is known. In addition, there are a railroad snow melting device (for example, see Patent Document 1) and an electromagnetic induction type heat generator (for example, see Patent Document 2) as an electromagnetic induction type heater using an E-shaped magnetic core.

特開2002−21003JP2002-21003 実用新案登録第3112603号Utility model registration No. 3112603

従来のラジエーターは高温度の熱源を利用するもので、スチームラジエーターはボイラーで発生した水蒸気を用いるので設備の大型化が避けられず、また、電熱ラジエーターは電気ヒーターを用いるのでエネルギー効率が悪く経済性に課題があった。一方、エネルギー効率を改善するために磁性コアを用いる電磁誘導式発熱器が上記特許文献1及び2に開示されている。特許文献1はE字型磁性コアをレール側面に密着させ、該コアに配線した励磁コイルに高周波電流を通電することによりレールに渦電流を発生させ、発熱したレールでレール上に積雪する氷雪を融かすと言う融雪装置であり、特許文献2は励磁コイルを配線したE字型磁性コアを発熱用金属薄板に固定して一体化した電磁誘導式発熱器で、高周波電流を励磁コイルに通電することにより発熱用金属薄板に渦電流を生じさせて金属薄板を発熱させると言う発熱器である。  Conventional radiators use a high-temperature heat source, steam steam uses steam generated in the boiler, so the size of the equipment is unavoidable, and electric heaters use electric heaters, making them less energy efficient and economical There was a problem. On the other hand, Patent Documents 1 and 2 disclose electromagnetic induction heaters using a magnetic core in order to improve energy efficiency. In Patent Document 1, an E-shaped magnetic core is brought into close contact with a rail side surface, and an eddy current is generated in the rail by energizing a high-frequency current to an exciting coil wired to the core. This is a snow melting device that melts. Patent Document 2 is an electromagnetic induction type heat generator in which an E-shaped magnetic core with an exciting coil wired is fixed to a heating metal thin plate and integrated, and a high-frequency current is passed through the exciting coil. Thus, the heat generator generates heat by causing an eddy current to be generated in the heat generating metal thin plate.

ところで、E字型磁性コアの電磁誘導により発生する電磁界は、E字コアの中心極と外側極の両極間とに閉磁路を形成するので金属発熱体(特許文献1ではレール、同2では金属薄板)に渦電流を効率良く発生させることができると言う効果があるが、しかし、そのためにコア外側両極から外側に向かう磁束の発生が弱いので、隣り合うコア同士の相互誘導作用が小さく、コア間には渦電流の発生が小さい。広い面積を加熱するためには多数個のコアを近接して配置する必要があり、大面積加熱用には適さない。本考案は広い面積を加熱することができるエネルギー効率の高いU字型磁性コアによる電磁誘導加熱式ラジエーターを提供することを目的とするものである。  By the way, the electromagnetic field generated by the electromagnetic induction of the E-shaped magnetic core forms a closed magnetic circuit between the center pole and the outer pole of the E-shaped core. It has the effect that eddy currents can be generated efficiently in the metal thin plate), but because of this, the generation of magnetic flux from the core outer poles to the outside is weak, so the mutual inductive action between adjacent cores is small, There is little generation of eddy current between the cores. In order to heat a large area, it is necessary to arrange many cores close to each other, which is not suitable for large area heating. An object of the present invention is to provide an electromagnetic induction heating type radiator using an energy-efficient U-shaped magnetic core capable of heating a large area.

本考案は、高周波電源装置と励磁コイルを配線したU字型磁性コアを2個以上配置固定した電気伝導性放熱板とを組み合わせたことにより上記課題を解決したものである。すなわち、良く知られていろようにU字型磁性コアは、コア1個を励磁すると、U字型磁性コアの両極から発生する磁束は、両極の内側間には閉磁路を形成するが、外側間には外に放散する磁束を形成するので、コアから発生する磁束が分散し、対向する金属板など電気伝導性板に生じる渦電流は弱く、E字型磁性コアより発熱効果が劣るものである。しかしながら、U字型磁性コアを電気伝導性放熱板上に間隙を空けて2個を配置固定すると、励磁されたU字型磁性コアから発生する磁束は、コア両極の内側間に閉磁路を形成し、また、外側極から放散する磁束も隣り合ったU字型磁性コアの間に相互誘導作用による閉磁路を形成するので、隣り合ったU字型磁性コアの間隙にも渦電流が発生して発熱する。このことを利用して、2個以上のU字型磁性コア用いることにより、より広い面積の電気伝導性板を少数のU字型磁性コアで均等に、しかも高いエネルギー効率で加熱することが出来るU字型磁性コアによる電磁誘導加熱式ラジエーターを完成した。The present invention solves the above-mentioned problems by combining a high-frequency power supply device and an electrically conductive heat radiating plate in which two or more U-shaped magnetic cores wired with excitation coils are arranged and fixed. That is, as is well known, when a U-shaped magnetic core excites one core, the magnetic flux generated from both poles of the U-shaped magnetic core forms a closed magnetic path between the two poles. A magnetic flux radiating to the outside is formed between them, so the magnetic flux generated from the core is dispersed, the eddy current generated in the electrically conductive plate such as the opposing metal plate is weak, and the heat generation effect is inferior to the E-shaped magnetic core. is there. However, if two U-shaped magnetic cores are placed and fixed on an electrically conductive heat sink with a gap, the magnetic flux generated from the excited U-shaped magnetic core forms a closed magnetic circuit between the inner sides of the core poles. In addition, the magnetic flux dissipated from the outer pole also forms a closed magnetic path due to the mutual induction action between the adjacent U-shaped magnetic cores, and eddy currents are also generated in the gaps between the adjacent U-shaped magnetic cores. Fever. Utilizing this, by using two or more U-shaped magnetic cores, it is possible to heat an electrically conductive plate having a larger area evenly with a small number of U-shaped magnetic cores and with high energy efficiency. An electromagnetic induction heating radiator with a U-shaped magnetic core was completed.

本考案のU字型磁性コアによる電磁誘導加熱式ラジエーターは、U字型磁性コアを2個以上用いることにより、隣り合ったU字型磁性コアの間にも有効に渦電流を発生するので、広い面積の電気伝導性放熱板を少ない磁性コアを用いて均等に加熱することができると言うエネルギー効果と、使用電力のエネルギー効率が高いと言う経済効果を奏する。また、高温の熱源を使用しないので安全であり、高周波電流を用いることで懸念される電磁波漏洩もU字型磁性コアが電気伝導性放熱板に固定して一体化しているので、電気伝導性放熱板が発生する電磁波を吸収して電磁波漏洩を防止する効果を発揮する。  The electromagnetic induction heating type radiator using the U-shaped magnetic core of the present invention generates eddy currents effectively between adjacent U-shaped magnetic cores by using two or more U-shaped magnetic cores. There is an energy effect that an electrically conductive heat radiation plate having a large area can be heated evenly using a small number of magnetic cores, and an economic effect that the energy efficiency of the power used is high. In addition, it is safe because it does not use a high-temperature heat source, and electromagnetic leakage that is a concern due to the use of high-frequency current is integrated with the U-shaped magnetic core fixed to the electrically conductive heat sink. Absorbs the electromagnetic waves generated by the plate and exhibits the effect of preventing electromagnetic leakage.

The electrically conductive heat radiating plate 1 uses a stainless steel plate having a width and width of 500 mm and a thickness of 1.0 mm. The U-shaped magnetic core 2 uses a composite material made of manganese zinc ferrite powder and 12 nylon resin as a soft magnetic material. The shape is formed into a U-shape with a length of 50 mm, a height of 20 mm, a width of 30 mm, and a core pole thickness of 8 mm. Four pieces are arranged on the heat sink 1 with a gap of 200 mm as shown in FIG. Fix with thermosetting adhesive. Next, the exciting coil 3 uses four bundles of 114 enamel thin wires having a diameter of 0.15 mm / bundle and two bundles of PVC-coated litz copper wires, and the four U-shaped magnetic cores are wired in series as shown in FIG. . The high frequency power supply device 4 was a commercially available IH stove power supply unit having an electric capacity of 1.4 kilowatts, and an excitation coil 3 was connected to the terminal 5 to create an electromagnetic induction heating radiator with a U-shaped magnetic core. .

次に、作成したU字型磁性コアによる電磁誘導加熱式ラジエーターのスイッチ6を、100ボルトの交流電源7に接続し、高周波電源装置4により周波数20キロヘルツ、出力100ワットで励磁コイル3に通電した。そして、放熱板1の表面に設置した熱電温度計(図示せず)により放熱板1の表面温度の変化を測定した。また、熱電温度測定制御装置(図示せず)により放熱板1の表面温度を35℃に設定した。また、電磁波の漏洩はFMラジオを用いて雑音発生の有無で観測した。  Next, the switch 6 of the electromagnetic induction heating type radiator using the created U-shaped magnetic core was connected to a 100 volt AC power supply 7, and the excitation coil 3 was energized by the high frequency power supply device 4 at a frequency of 20 kHz and an output of 100 watts. . And the change of the surface temperature of the heat sink 1 was measured with the thermoelectric thermometer (not shown) installed in the surface of the heat sink 1. FIG.

Further, the FM radio placed in the vicinity of the heat sink 1 did not generate noise.
