Abstract
Description
本発明は、発熱体に関し、特に、真水等に発熱体を浸漬した場合にでも発熱を生じさせることの出来る発熱体合金に関する。 The present invention relates to a heating element, and more particularly to a heating element alloy capable of generating heat even when the heating element is immersed in fresh water or the like.
例えば、水道水を給湯する場合、通常のジュール熱を発生させるニクロム線を用いた給湯器では、スイッチオンして30〜60秒以上の時間で常温から40℃の給湯ができる。また、家庭用でもオフィスビル用でも、通常の場合、給湯器は使用する蛇口から遠い所に設置され、必要なお湯が出るまで給湯器から蛇口までの水は捨てることになる。 For example, when tap water is supplied, a water heater using a nichrome wire that generates ordinary Joule heat can supply hot water from room temperature to 40 ° C. in a time of 30 to 60 seconds or more after switching on. Also, for both home and office buildings, the water heater is usually installed far from the faucet to be used, and the water from the water heater to the faucet is discarded until the required hot water comes out.
ビルなどは使用頻度が高いので、配管内に待機している温水が有るが、配管内に待機する場合、常に温度が大気中に放散されエネルギーロスとなり、使用電力や各種の使用エネルギーの浪費となってしまう。 Since buildings are frequently used, there is hot water waiting in the pipes, but when waiting in the pipes, the temperature is always dissipated into the atmosphere, resulting in energy loss, which wastes power and various types of energy. turn into.
また、例えば、ガス調理器で鍋を使用して調理をする場合、ガスの炎は瞬間的に鍋の側面を通過してしまい、鍋を温めるエネルギーの効率が低く、更に、ガスの炎から発散している熱の多くは鍋による反射として放散してしまい、鍋を温めるエネルギーの多くは発散してしまう。換言すると、ガスの炎から出される熱風の一部はほんの少しだけ鍋に接し、多くの熱は鍋の表面に触れ、熱伝導することなく放散されてしまう。 Also, for example, when cooking using a pot with a gas cooker, the gas flame momentarily passes through the side of the pot, the energy efficiency for heating the pot is low, and the gas flame diverges. Most of the heat generated is dissipated as a reflection of the pot, and much of the energy that heats the pot is dissipated. In other words, some of the hot air from the gas flame touches the pot only a little, and much of the heat touches the surface of the pot and is dissipated without heat conduction.
このため、例えば、特許文献1に示されるように、ニッケルに、インジウムとチタンと他の金属を含んだニッケル基合金を用いた発熱体が提案されている。 Therefore, for example, as shown in Patent Document 1, a heating element using a nickel-based alloy containing indium, titanium, and other metals in nickel has been proposed.
特許文献1の発熱体によれば、インジウム/ニッケルの質量比が0.001〜0.2、チタン/ニッケルの質量比が0.03〜0.3であるので、通電したときに瞬時に所定の高温に到達することができ、発熱効率に優れ、かつ通電耐久性が優れ、そして加工性が良好な発熱体を経済的有利に提供することができる、としている。 According to the heating element of Patent Document 1, the mass ratio of indium / nickel is 0.001 to 0.2 and the mass ratio of titanium / nickel is 0.03 to 0.3, so that it is instantly determined when energized. It is said that it is possible to economically advantageously provide a heating element that can reach the high temperature of the above, has excellent heat generation efficiency, has excellent energization durability, and has good workability.
また、特許文献2に示されるように、鉄クロムに、インジウムとチタンと他の金属を含んだ鉄クロム基合金を用いた発熱体が提案されている。 Further, as shown in Patent Document 2, a heating element using an iron-chromium-based alloy containing indium, titanium and other metals in iron-chromium has been proposed.
特許文献2の発熱体によれば、インジウム/鉄クロムの質量比が0.001〜0.2、チタン/鉄クロムの質量比が0.02〜0.3であるので、通電したときに瞬時に所定の高温に到達することができ、発熱効率に優れ、かつ通電耐久性が優れ、そして加工性が良好な発熱体を経済的有利に提供することができる、としている。 According to the heating element of Patent Document 2, the mass ratio of indium / chromium iron is 0.001 to 0.2, and the mass ratio of titanium / chromium iron is 0.02 to 0.3. It is said that a heating element that can reach a predetermined high temperature, has excellent heat generation efficiency, has excellent energization durability, and has good workability can be economically advantageous.
また、それぞれに、合金中における元素の成分比、印加電圧および発熱体の形状を調整すれば、発熱体の発熱量を所望の水準に自動調整することができる、としている。 Further, by adjusting the component ratio of the elements in the alloy, the applied voltage and the shape of the heating element, the calorific value of the heating element can be automatically adjusted to a desired level.
しかしながら、特許文献1に記載されたニッケル基合金を用いた発熱体および特許文献2に記載された鉄クロム基合金を用いた発熱体によれば、以下のような問題があった。
(1)インジウムを含んだ発熱合金は、瞬間発熱と電気的低抵抗値が特徴であり、抵抗値が低いゆえに大電流が流れてしまうという問題があった。
(2)真水等の水に発熱体を浸漬したり取り出しを行うと、平板電極表面には錆が発生したり、即座に平面が歪んで変形してしまい、精密環境の収容容器中に収納して発熱させる場合、錆が溶出してしまったり、歪みで金属同士が接触してショートしてしまったり、発熱体と装置との接触面が不均等になって熱伝導率低下が発生したり、樹脂で覆った場合に歪みが原因で被覆に亀裂が生じたりするという問題があった。
(3)突入電力が瞬間的に大きくなり、それに対応する定格以上の配線等が必要になるという問題があった。
(4)電源ONの瞬間のオーバー電力による消費電力の損失や、突入電力上昇による消費電力削減の為に、一秒間に1〜10回又は20回等のスイッチングスイッチの採用などには突入電力上昇現象は不都合であるという問題があった。However, the heating element using the nickel-based alloy described in Patent Document 1 and the heating element using the iron-chromium-based alloy described in Patent Document 2 have the following problems.
(1) The heat-generating alloy containing indium is characterized by instantaneous heat generation and a low electrical resistance value, and has a problem that a large current flows because the resistance value is low.
(2) When the heating element is immersed in fresh water or taken out, rust is generated on the surface of the flat plate electrode, and the flat surface is immediately distorted and deformed, and the heating element is stored in a storage container in a precision environment. When heat is generated by heating, rust may elute, metals may come into contact with each other due to strain and short-circuit, or the contact surface between the heating element and the device may become uneven, resulting in a decrease in thermal conductivity. There was a problem that the coating was cracked due to distortion when covered with a resin.
(3) There is a problem that the inrush current increases momentarily, and wiring or the like corresponding to the rated power or the like is required.
(4) Inrush power increases when switching switches are used 1 to 10 times or 20 times per second in order to reduce power consumption due to overpower at the moment when the power is turned on and power consumption due to inrush power increase. There was a problem that the phenomenon was inconvenient.
これらの原因は、インジウムの電子量が少なく、それによる高い熱膨張率、硬度および剛性率に起因することや突入電力が瞬時に高くなることにある。 These causes are due to the small amount of electrons in indium, which results in high coefficient of thermal expansion, hardness and rigidity, and the instantaneous increase in inrush current.
従って、本発明の目的とするところは、電源を印加した瞬間に電圧が急上昇することなく、瞬時に所定の高温度帯に到達することができ、真水等に発熱体を浸漬した場合にでも発熱体に歪みを生じさせることのなく、発熱効率に優れ、かつ通電耐久性が優れ、かつ加工性が良好な発熱体を提供することにある。 Therefore, an object of the present invention is that the voltage can reach a predetermined high temperature zone instantly without a sudden rise in voltage at the moment when a power source is applied, and heat is generated even when a heating element is immersed in fresh water or the like. It is an object of the present invention to provide a heating element which is excellent in heat generation efficiency, excellent in energization durability, and good in workability without causing distortion in the body.

より具体的には、鉄クロム基合金、ニッケル基合金に対して、1)チタンとインジウム2)インジウムとパラジウム、3)インジウムとビスマス、4)チタンとインジウムとパラジウムとビスマス、5)ロジウムとルテニウム、6)チタンとインジウムとビスマス、7)チタンとインジウムとパラジウムとルテニウムの7通りの何れかの配合を行うことが望ましい。 More specifically, for iron-chromium-based alloys and nickel-based alloys, 1) titanium and indium 2) indium and palladium, 3) indium and bismuth, 4) titanium, indium, palladium and bismuth, and 5) rhodium and ruthenium. , 6) Titanium, indium and bismuth, 7) Titanium, indium, palladium and ruthenium are preferably blended in any of seven ways.
これらを配合するのは、剛性率が強く(チタン44、ロジウム150、ルテニウム173)、膨張率が低く(チタン8.6、ロジウム8.2、ルテニウム4.4、パラジウム11.8)、モース硬度が硬く(チタン6、ロジウム6、ルテニウム6.5、パラジウム4.75)、電気抵抗が少ない(チタン420Ω、ロジウム43Ω、ビスマス1.29Ω、ルテニウム71Ω、パラジウム105Ω)ので発熱の抵抗が小さく、突入電力が大きくならないことに加え、密度も高い(チタン4.506、ロジウム12.4、インジウム7.3、チタン4.5、ニッケル8.9、クロム7.19)ことから変形しにくい上に錆びにくさも兼ね備えているためである。配合比としては、それぞれ同量の配合量とする。 These are blended with high rigidity (titanium 44, rhodium 150, ruthenium 173), low expansion rate (titanium 8.6, rhodium 8.2, ruthenium 4.4, palladium 11.8), and moth hardness. Is hard (titanium 6, rhodium 6, ruthenium 6.5, palladium 4.75) and has low electrical resistance (titanium 420Ω, rhodium 43Ω, bismuth 1.29Ω, ruthenium 71Ω, palladium 105Ω), so heat generation resistance is small and plunge. In addition to not increasing the power, the density is high (titanium 4.506, rhodium 12.4, indium 7.3, titanium 4.5, nickel 8.9, chromium 7.19), so it is hard to deform and rusts. This is because it also has difficulty. The blending ratio shall be the same amount for each.
これらの元素の酸化物の使用量は、合金を100質量%としたときに、鉄クロム、ニッケルおよびインジウムの酸化物の量を100質量%から差し引いたバランス量を用いる。 As the amount of oxides of these elements used, the balance amount obtained by subtracting the amount of oxides of iron chromium, nickel and indium from 100% by mass is used when the alloy is 100% by mass.
さらに、これらの元素の鉄クロム基合金、ニッケル基合金に対する配合比は、0.01〜5%であることが、より良好な発熱体の発熱量の大きさ、発熱即応性および長期使用時の劣化防止の観点から望まれる。 Further, the compounding ratio of these elements to the iron-chromium-based alloy and the nickel-based alloy is 0.01 to 5%, which is better for the magnitude of calorific value of the heating element, heat generation responsiveness, and long-term use. It is desired from the viewpoint of preventing deterioration.
